This result is amazing. I was considering buying these two chips:
https://www.ebay.es/itm/Intel-Xeon-...=item2604adc264:g:FzIAAOSwDYxbsOFO:rk:14:pf:0 and possibly OC them to 3.6GHz. Are these QS chips a good idea? I was looking for 18 core xeon, but non-ES chips are still quite expensive.
QS chips are usually production stepping. Make sure never to get anything that is QExx.
QFxx, QGxx appear to be same stepping as retail usually.
What is the max turbo for all cores that someone managed to achieve using E5-2698 v3 or E5-2697 v3?
What you see in the screenshot is the absolute max overclock I was able to get. That was actually not stable and I had to back off to 105.3 MHz in bios, was getting some Nvidia driver crashes and some PCIE related errors in event viewer.
I tried for the full 3.9 GHz, but one of the procs failed to initialize at 105.8 MHz bus.
I'm satisfied with the result, turned out a lot better than I thought it would.
Hi one additional question ...
what this mean ? where did you left the microcode update ? in Windows ?
Thanks !
Would be great to run e5 2697 v3 [QS] at x37
@ziollos - I have QS version of CPU and it does work flawlessly !
Yes, I left the latest Intel microcode update that Microsoft pushed out to address some of the Spectre exploits. Apparently Microsoft will be releasing mitigation for performance issues related to Spectre, so I don't really feel the need to play around with the older microcodes.
I had for e5 2697 v3[QS] :
- 1-11 cores - turbo 3.6 ghz (x36)
- 12-13 cores - turbo 3.5 ghz (x35)
- 14 cores - turbo 3.4 ghz (x34)
But now I see the x37 can be even achieved ... need to check that
I think the turbo boost you will see are dependent on your board and possibly how good your procs are. Also different workloads will produce different all-core turbo.
Also, if you're running a Z10PE-D8 WS or the -D16, you probably will have to get a bios programmer and a separate bios chip to program with the modded bios.
I was completely unable to use bios flashback to get the modded bios in place.
