First Intel Quad Core Ready Desktop Mobo Spotted

CowboyNeal posted more than 8 years ago | from the hot-off-the-presses dept.


MojoDog writes "Today Universal Abit launched their AW9D and AW9D-MAX motherboards based on the Intel 975X chipset. There has been much anticipation in the industry for this series and as far as looks go, these boards are built to please. One interesting bullet point in the spec list is that these boards are "Quad Core Ready", in line with a possible year-end release of Intel's Quad-Core Kentsfield CPU perhaps? Time will tell!"

Will that make the Mac Pro any cheaper? Or maybe a quad-core iMac a possibility?

Re:But! (5, Informative)

nxtw (866177) | more than 8 years ago | (#15940950)

no, these motherboards are for the LGA775 socket, not the LGA771 socket used by the Xeons in the Mac Pro or the Socket 479 used by the iMac/Mac notebooks/Mac mini.

"Clovertown" may be a quad-core version of the "Woodcrest" Xeon chips used in the Mac Pro, although I couldn't find anything definitive.

I'm not sure if Intel has any plans for quad-core mobile chips (the Core Duo used in the iMac/Mac Mini is the mobile-oriented chip, but has shown up in smaller desktop computers incl. the Macs).

Re:But! (5, Informative)

FuturePastNow (836765) | more than 8 years ago | (#15941147)

Clovertown and Kentsfield are identical except for the socket and bus speeds they use. So, yes, Clovertown is the quad core version of Woodcrest (like Kentsfield, it's actually two dual-core processors on one package) and will work fine in the Mac Pro (unless Apple does something silly and uses firmware to block upgrades).

Re:But! (2, Interesting)

Tycho (11893) | more than 8 years ago | (#15941749)

Just for the heck of it I thought that I would list all of the things I could think of that would not allow one to use a quad core processor on a Mac Pro.

First off the new Clovertown processors must use the same socket and bus protocols as the Woodcrest processors. Even if the Clovertown processors use the same socket, the new processor must have the same pinout and must be electrically compatible with the Woodcrest processors. Another potential problem is that Clovertown could require new VRM specifications.

Finally that is all Intel can do to make the Mac Pro incompatable with the Clovertown processors. Additionally the proper microcode to support the Clovertown processor has to be in the firmware. (This may not be totally necessary as there are some x86 systems that will boot without the proper microcode for their processor. Additional software must be run to have the processor to work properly though.)

Finally, Apple could release a firmware "upgrade" that could make it so that on boot up on detection of a Clovertown processor the computer would not boot. Apple did this with the Blue and White G3 systems before releasing the G4 towers. Even though there is a G4 tower that uses the same chipset as the B&W G3, in their default state, after the firmware upgrade the B&W G3 systems will not boot with a G4 processor in a B&W G3. However, some enterprising individual made a firmware patch of their own to bypass this G4 ROM Block. Someone else could add the proper microcode and remove any firmware block on the Clovertown, but the problem would be how to flash the new firmware. (I would imagine that Apple/Intel might make flashing a third party firmware hard to do though.)

Re:But! (1)

FuturePastNow (836765) | more than 8 years ago | (#15942059)

Well, the motherboard should support the new processors just fine, as far as electrical and bus compatibility. It may well require a firmware update to work, but unless Apple plans to redesign the Mac Pro's motherboard in January, they will have to make such an update. If they don't make that update available to existing Mac Pros, someone will get their hands on it and release it. Likewise, if Apple modifies the firmware to exclude newer CPUs, someone will hack it pretty quickly.

I can think of one other reason why Clovertown may not work in a Mac Pro- heat. Woodcrest has a TDP of 65W; Clovertown, which is little more than two Woodcrests stuck together, is 100+W. Being obsessed with quiet/silent computing, Apple may be running the Mac Pro's processors hot already so the fans spin very slowly (I don't know how hot the Mac Pro's processors get- I suspect, with those huge heatsinks, they actually run pretty cool).

That's something I've never even thought of. Are you allowed to upgrade a CPU in a Mac? I usually just throw away my old Macs when I get a new one and have never even considered the possibility of upgrading the components in them.

I think he was actually meaning that because quad-core will be available in a 'desktop' chip, the 'quad core' systems Apple is selling should drop in price. (After all, if you could get a quad core iMac at 2.93 GHz, why pay $2000 more for a quad core Mac Pro at 3.0 GHz?)

But, I have it on good authority (inside information, hence my AC posting,) that the server quad-core chips will come out first. So it will be more likely that the Mac Pro will become an eight-core system. (I have no inside info at Apple, only Intel.) The quad core Xeons will be coming out this year. The desktop chips aren't so certain, and may be delayed until January. (Also, the desktop chips WILL be moving to a 1333MHz bus, at least for the 'Extreme' parts, so if you want 'future-proofing', I would avoid any motherboard that doesn't support this bus speed.)

You'd pay $2000 more to get a double quad core cpu, but still I do agree with you that the price of the Mac Pro isn't justified, the iMac's aren't that much worse for a _really_ big difference in price.

Their 965-based AB9 Pro is not very good. (2, Interesting)

nxtw (866177) | more than 8 years ago | (#15940921)

I have a AB9 Pro Intel 965-based board here with a Core 2 Duo E6400, and I can't get it to boot half the time. I get an error code 8.7. on the motherboard's LCD, which means "Check CPU Core Voltage". When it does boot, I occasionally get an error or "Device Verify Failed" from the AHCI BIOS while identifying my hard drives.

The system is impressively fast when it actually boots and works, but those two issues make the motherboard very difficult to actually use.

DeadMeat (TM) (233768) | more than 8 years ago | (#15941693)

Unfortunately, I can verify the AHCI problem. In my case, it claims the device verification fails whenever I soft-reboot. It's annoying enough that I just run the SATA controller in Legacy IDE mode.

Otherwise, though, my AB9 Pro has been reasonably solid. Considering the dearth of good 965 motherboards -- and the expense of Conroe-compatible 975 motherboards -- it's probably the best of a limited pack right now.

As far as I know ECC capability depends on the chipset used. The intel 875, 925, 955 and 975 chipsets have ECC capability, the 865, 915, 945 and 965 do not. These new ABit mainboards probably have ECC support although their website says they don't.

I've run multiple systems with non-ECC memmory. Uptime was originaly limited by time between brownouts/blackouts (~3 months). Then I got a UPS and uptimes have only gone up. If you need ECC to keep your system up for more than a week, you've got problems.

Re:Why no ECC? (4, Interesting)

ctr2sprt (574731) | more than 8 years ago | (#15941148)

Agreed, but bear in mind that a single-bit error doesn't have to crash your system (or an app). In fact, it usually won't, because the amount of "critical" memory is very small relative to the total amount of RAM installed. Instead it will silently corrupt data. This could result in a momentary glitch in what's shown on the screen; it could result in an app delivering nonsensical results; or, far worse, it could result in bad data being written to disk or an app delivering subtly wrong results. Since all modern operating systems use all memory in your box for something (cache, usually) pretty much every single-bit error is going to screw something up.

I work with many ECC-using servers and there are typically one to five single-bit errors per month. Even though I understand the reasons for it, I am kind of bewildered that ECC isn't more common on high-end desktop systems. The RAM costs ~15% more, but gamers, for instance, are already willing to pay 50% markups (or more) for a 1% performance bump (if that). You could even market it as overclocker-friendly: the error checking will tell you when you're overclocking too high, and the error correcting will help you when you're right on the edge. It could also allow overclockers to identify DIMMs which can't keep up without the laborious process of "pull out a stick, run memtest overnight; put stick back in, pull out a different one, run memtest overnight; etc." (Or the worse one when DIMM has to be installed in pairs. Then you get the joy of testing every combination.)

It's true that you probably won't get a system-crashing memory error every week, but memory errors do occur, and they can crash systems or applications and corrupt data. Certainly you recognize that.

Re:Why no ECC? (3, Insightful)

DrDitto (962751) | more than 8 years ago | (#15941483)

If you live in high altitude areas, ECC RAM is really necessary if you want reliable computing. Even with ECC, higher-end servers will "scrub" memory by periodically reading out every memory block to correct single-bit errors before they become double-bit errors.

The Virginia Apple Supercomputer initially used non-ECC nodes. Couldn't keep the machine up and they ended up selling off all of the original Xserve machines to get ECC Xserve's.

At Los Alamos altitude, the problem is even worse. It isn't uncommon for non-ECC workstations to crash every other day.

Re:Why no ECC? (2, Informative)

Ironsides (739422) | more than 8 years ago | (#15941571)

Uh.. What does altitude have to do with ECC? I'm guessing you mean the Virginia Tech apple supercomputer. Altitude in blacksburg VA is maybe 1000 feet above sea level.

Re:Why no ECC? (4, Informative)

VENONA (902751) | more than 8 years ago | (#15941770)

Cosmic rays can flip a bit, and have biological effects. Cosmic ray arrival rates are related to your altitude. Blacksburg VA may be only a thousand feet up, but Los Alamos is more like 8-9K--can't remember, exactly. But it's considerably higher than Santa Fe, which is about 7K.

Also, you may not be able to accept single-bit errors, even at the lower rate you'd experience at sea level. What's good enough for a Joe Gamer's PC in Denver (5K feet) may not be remotely good enough for mission-critical servers. Wall Street is at sea level, for the purposes of this discussion. But you can bet they don't always look at random bit-flips kindly.

As usual, how you spec a machine depends upon what you're planning to do with it. That even filters down into whatever spares you may stock for a server farm. Compare mfg. memory prices for large multi-CPU (think 8-64 CPUs, not some generic 4-way) servers running Solaris or HP-UX to memory available from the mass market vendors. Last time I did that, the mfg. memory was about 10X more expensive than something generic that would at least boot your system.

In that environment you need to be sure that the memory you're buying really is equivalent--not just that the machine will still boot. In that case, BTW, it turned out that there was equivalent memory available, without paying a huge vendor markup. It wasn't as cheap as the rock-bottom stuff (which would still have yielded a bootable machine) but it was cheap enough to justify buying a (much cheaper) machine just to stress test it before adding it to the ready spares bin for production systems. Sometimes a four hour support contract is still too slow, but you don't want to pay six figures for a hot backup system. Which also has to be under that expensive service contract.

If you have TB of memory to deal with, and mission-critical means minimize or eliminate flipped bits, the rules change considerably. It's a whole different world.

God only knows what gyrations the NSA must go through. Oh, wait, they just pay vendor rates, no matter the cost. My tax dollars at work...

No kidding: I have a Dell 6850 in my basement handling Asterisk and various Xen/VMware tasks. I've bought an additional 24GB of buffered ECC RAM from NewEgg and saved well over $5K vs buying the same memory from Dell... Dell's diagnostics don't even notice the non-Dell memory and if the system ever notices an ECC error it lets you know the exact bank that is to blame. But buffered & ECC 2G and 4G sticks are still pricey, even at NewEgg prices.

tuxicle (996538) | more than 8 years ago | (#15941863)

At high altitudes, there's less atmosphere between you and outer space, so cosmic rays and other ionizing radiation don't face as much resistance through scattering.

I work at a research radar near Fort Collins, CO (alt: 1432m), and we have a Sun Blade 1000 with ECC, whose motherboard emits a curious "burp" sound each time it detects a memory error. It seems to do this about once every two hours. Also, the radar transmitters can sometimes emit small amounts of X rays. I've not noticed any increase in the "burps" when we've got the transmitter on.

The Quad Core chips are not final yet and that will say support in till they are out and you may need a bios update or newer mother board rev.

Any ways AMD is Better because they say that am2 cpus will work with am2 boards not like Intel where some boards with the same chip set do not alleys support new cpus.

Of course some people are always going to want to have the fastest game machine on the block. But seriously, it's amazing the kind of performance you can get these days with cheap, low-end hardware. Yesterday I built a machine for $300 with a 3 GHz P4 and 1 Gb of ram. (I reused a hard disk, so that cut the price a little.) Sure I could have built a dual-core system, but I would have ended up with a machine that cost many times more, used tons of power, and had almost identical performance except when I had two cpu-intensive processes running at once (i.e., almost never).

Re:insanity (0)

Pretty sure a low-end AMD X2 will draw less (/w Cool'n'Quiet taken into consideration) than your P4. It wouldn't be as cheap though. In fact, the X2s will draw about the same as the single cores [] . The P4 is great for short-term up front cost, but long term, not so nice.

ECC is a good thing (1)

lsatenstein (949458) | more than 8 years ago | (#15952604)

For non critical application systems, (home computers, or systems with small databases, you can do without ECC memory. Just as you can do without car insurance.

Suppose you have a terrabyte database and you have not used ECC memory. Suppose that a single bit error got into the database undetected. And some months later, the records or pointers or tree of data with the corrupted bit is corrupted. What would be the cost of repair against the cost of having ECC memory installed?

My understanding of ECC Memory operation.

Memory addresses are divided into words. The simplist design of ECC memory takes a check sum of the bits of a word of memory and of itself. Thus, for example, a 32 bit word would need 5 bits to hold a check sum, but then we have the ecc memory that is needed to store the checksum and of course, its own check sum. That adds at least a few more bits. To check 64 bit words only takes another bit, over using a 32 bit word.

The theory is, that for any single bit error, the error would be corrected on the fly and would be transparent to the application. In more sophisticated systems, the same holds true, but the error would also be reported as a soft error. A diagnostic processor in the system would analyse the ECC errors and distinguish between random soft and persistent hard failures.

ECC hardware detection would detect errors with more than a single bit would halt the system.

When ECC memory systems are well designed, you can pull out a card with faulty memory and replace the card with a repaired one. System design would have the card only support a single bit in a word, distributed over many the words of memory. After replacement, the access of memory would result in the rewrite of memory in the replacement card, resulting in generating the correct bit setting.

Our lowly PCs do not have that sophistication, but some mainframe systems do.

Well, the dual cores kind of suck because they only have one math co processor. The cores have to share it, so you really don't get double the power for real math stuff.

That was a real bummer for me.

Fashonably Late or Not Fast Enought? (2)

Probably both. AMD released there press announcement [] on Tuesday. Intel, are you slacking off or are you not as fast as AMD?

Clovertown has been taped out for a while. Trust me on that one. Intel also has the ability to go from tape-out to production faster than AMD.

Quad Core vs Dual Core vs 3 Cores? (1)

In queuing theory, and in practice, it is well known that in a multiple server environment, the shortest time to service occurs when there is a single queue facing multiple servers. The first task in the ready queue goes to the next available server. Service is from task initiation to task completion.

With this above configuration, the average queuing time, and hence service time is much less than if there is a dedicated queue per server.

From what I have seen, with multiple core systems, there appears to be a dispatcher per server, so that queues are the type that you find in grocery store check out counters (a queue per server). Throughput time is longer than if there was one server dedicated to dispatching and the others dedicated to running tasks.

The other thing that comes out of all the research and experience, is that 2 servers that execute twice as fast as the 4 servers provide higher throughput.

So, why the big fuss about quad core, unless it is to save real-estate or electrical connections. Give me dual core that executes twice as fast and I will be happier.

I actually think that a three core system, (a dispatcher cpu, and two server cpus) would be just fine. Now, to confirm that all operating systems use a single dispatcher and multiple server configuration I count on the operating system developers to check things out.

FYI. My background is that I have more than 40 years in Computer Capacity Planning, System Tuning and system development. I am a mathematician (applied) who uses this talent to my max.

You should be, I survived 50 years in the business and still going strong. And I have a well respected reputation. I love what I do and I do teach others. I even soldered an old backplane computer together. Thank you for the accolades.

Are you sure you didn't make that up after watching an episode of the tv show called "Numbers"?
