Precision T3600 Workstation CPU upgrade, cpu stepping
Hello.
I am going to upgrade my T3600 Workstation with a new CPU. There are a number of them sold on ebay now, but there is no info in those announcements regarding which of the 3 steppings intel produced of the E5-2670 cpu is inside them.
Does anyone have this cpu installed in their T3600 machine out there? Could you help a fellow? Should be in the bios under system information... or on the actual purchase receipt when you upgraded.
There are 3 steppings:
www.cpu-world.com/.../Intel-Xeon%20E5-2670.html
What it says there is that the 3 steppings are "C0" (QB7A), "C1" (QBF5, SR0H8) and "C2" (QBV7, SR0KX). Now, if you don´t know the specifics of your cpu, just look in the bios for any of the above numbers that are in parenthesis, aka "QBV7, SR0KX", anything like that.
Also, if you could give the bios version and revision of the revision of the motherboard/mainboard, that would of course be genius, but I´ll take anything anyone has to offer me at this point.
Thanks for any help!
Best Regards

There wont be any Spec with a Q in it. Q numbers are Engineering samples. Therefore C1 or C2 would be the only ones in production.

Always update to the latest bios BEFORE changing CPU.
"C0" (QB7A), "
C1" (QBF5, SR0H8)
"C2" (QBV7, SR0KX).

Thanks a lot for the info. But does this mean that any of the two steppings C1 or C2 will work??

I can confirm, with A12 BIOS, the SR0KX works, just did the upgrade this morning from the quad core E5-1603.

Thanks "SpeedStep" for the answer, good to know C0 is not a real revision/stepping!

Thanks a lot for your answer. I have the other C1 here, gonna try to downgrade to the A12 bios (I currently have A14) and try to get this one to work.
By the way, did you try the diagdostics software? My cpu was fine until i tried to start Windows 8.1 or the diagnostic, which was initially fine, until it got stuck on the memory modules.
Thanks again for the reply!!

I have not upgraded BIOS, still on A12.
Using 4x8gb DDR3 1333 UDIMM memory from Kingston 2Rx4.

" I can confirm, with A12 BIOS, the SR0KX works, just did the upgrade this morning from the quad core E5-1603. "
Okay so this is the C2 stepping, did you upgrade to the A14 bios by any chance? Also what´s your memory type, configuration and speed? (like ""4 x 4GB DDR3 1333mhz RDIMM ECC 2Rx4"" or so, the rank seems important and weather it´s RDIMM or UDIMM...)
Thanks for all the info you can give!!

Okay, but is that ECC or just UDIMM Non-ECC?
I actually reverted my BIOS from A14 to A13, and now my C1 E5-2670 is working with no issues, but with UDIMM ECC 4GB installed!
Thanks for telling me about A12, made me think!

Thanks! Just what I wanted to know. The prices on used E5-2670's are good since the market got flooded with them a while back.

I know this is old but ... It depends on what you want to do with it. For "normal" use, either the C1 or C2 stepping would work. However, be aware that the C1 stepping has broken support for VT-d.
That should not bother a Windows user. If you want to run a VMware hypervisor though, you won't be able to use DirectPath I/O (passthru), if you wanted to use that option. If not, you're good to go with either.
