Still some people with 2667v2 experience around?
I can't get it to turbo higher than 36x, but it is supposed to have a 40x Multiplier on 1T loads. I can get it to 39x when i limit to two cores in the BIOS, but whenever all cores are active i can't get higher clocks than 3600mhz even if the workload is purely signlethreaded. I trief hwinfo and it never leaves the 36x multimplier. I tried all the settings, c-states, no EIST, with EIST, additional turbo voltage, voltage offset minus/plus, undervolting, overvolting, etc.
Is it my cheap board with shitty VRM limiting me? The CPU runs a lot cooler than the 1650v1 and it never draws more than 95Watts too, while the former could easily best 165W at 4.2Ghz, so the board must have had some reserves. It feels like all the power settings for turbo power, current limit, etc. don't apply to 2600v2 xeons.
If i set the Multiplier manually to 40, my BIOS displays a 4Ghz clockspeed, but it never does that in windows. Is this a known windows10 problem, maybe because of the meltdown patches?
My board is an Asrock Xtreme3 with BIOS Version 2.90A with NVME support. It only has 5+1 Phases, but i added a beefier heatsink which improved VRMtemps by 10Degrees under load (its now 89C with 170W).
Is there some sort of turbo boost unlock with V2 Xeons too or was that limited to x99? I'd really like to achieve the 40x Multiplier.
