Hmm... I'm pretty sure ECC and or ECC Registered in certain circumstances is required for dual CPU operation. BUT, I can't swear to that.

Asus tech support yesterday mentioned a known issue with these boards, v2 Xeons and NON ECC RAM - check it out to be sure this isn't your problem?

In W8 I only had CPU1 avail but all RAM, now in W7 I have both CPU but apparently only RAM sticks 1 & 2 are working (CPU-Z info) which cannot be the case if CPU2 is working.

Running tests and updates now, will report back.

Hi
I was looking around this thread of the forum and couldnt find this info.
I was on ebay and looked at two Xeon e5-2687w c0 stepping QB7R and i was thinking on buying them and use them with the Asus Z9PE-D8. I was afraid of buying them for the fact of being es cpu's.
I have some Quetions: 1.Will i run in with any issue with the bios ?
2.Do they have the same performance as the release one?
3. Will any feature be missing?
4. Will i see any decrease in performance in casual gaming ?
5.Are they usable toguether as I heard that some steppings wont work?

Thanks

From what little I know... C0 stepping e5 v1 Xeons are "QS" production CPUs. Translation = nearly retail. Rarely are there changes in the process once a product goes from QS to retail production. QS is not a typical engineering sample, it's a quality sample and typically the type sent to magazines and websites for review.

Compatibility should not be a problem as several websites which reviewed this motherboard at release were using C0 QS chips. However, you might need to "downgrade" your BIOS to achieve stability.

Performance, stability, features... should be nearly if not exactly all the same as retail.

BTW, what defines casual gaming to you? I do not recommend this board for gaming.

After work playing some video games maybe put a gtx 780 ti would that work ?

Oh certainly, it will work... if gaming is truly a secondary function of your build, then it's not a bad idea. If gaming is your main objective, you can do so much (in fact, a LOT) better for a ton less money. biggrin.gif

The 780ti matched to a nice Xeon will play games just fine, although, you might find driver issues and or motherboard/bios quirks get in the way from maximum performance.

i Think i read somewhere that this xeons at release had c1 and c2 steppings.
Will the bios from the motherboard interfier with upgradability like in the future a raid card or new gen gpu's ?
As i have limited time for gaming I wanted to try to do some youtube vidios of gaming and tutorials also livestream at the same time thats why I dont really want to go with something like an i7 extreme

Probably... retail always gets a separate designation, however, that doesn't always mean there are functional differences with the fabrication.

As for the BIOS, it is certainly possible that at some point (Asus may already have) a release will disable compatibility with the C0 stepping CPUs. That is the risk you take with ES CPU's. Sure you save a ton of money, but down the line it might cost you a lot more to correct.

Basically, all you can do if you desire ES chips is build a system that is compatible with todays hardware and software... acknowledging the possibility that in the future you might not be able to upgrade any or all of the hardware in your system without the purchase of newer "retail" CPU's.

Ok I did some research around and there was one page that shows the model and it is a match as the problem with the virtualization can you be a little more specific does it still work ?

From everything I've read, some C0, even C1 revision ES CPU's demonstrate a problem with VT-d virtualization... which appears to be a problem many, MANY Intel ES CPU's suffer from.

They still work fine for virtualization in general, just not using the VT-d enhancements. Which, not being an expert on virtualization myself, doesn't seem all that important anyways. Assuming you follow proper security methodology, I don't see how isolation of data flow directly to client would provide much benefit.

If you're building this system for a corporate environment, and will be providing high level secure connectivity options, then you shouldn't be buying ES chips from God knows who anyways. wink.gif
