Help with underperforming e5 2690 v3

[all things hardware]

Hey all, I am in need of help from people with experience with the v3 xeons. My xeon is only getting 1867 in cinebench and is peaking at 3 GHz. I ran a userbenchmark test and my cpu was underperforming in it. What's the fastest speed i can get all the cores to run at and how can I do it? I'll gladly apply a bios mod or whatever I have to do to fix the problem as I have very adequate cooling.

Userbenchmark is crap for actual performance testing, and you shouldn't take the results there seriously.

That Xeon is 2.6 GHz base, and has an all core turbo of 3.1 GHz as far as I'm able to tell. Based on my past testing of Haswell, I'd estimate 12 cores at 3.1 GHz with HT on would have a Cinebench R15 score of 1871, so your actual score of 1867 is pretty much spot on.

 

I have heard of a way to overclock those CPUs but it was so painful I never even started it on my E5-2683v3. In essence, you had to somehow load onto the CPU an old microcode from before they locked down the multipliers. I think the preferred method was bios mod. Also ensure the rest of the system doesn't override that too e.g. you have to specifically stop Windows from applying newer microcode on boot. Even then, I think there was still a limit of the max turbo. A lot of pain for not a lot of gain.

Ok thanks, in the bios I can set the all core turbo to a multiplier of 35 but it never goes above 3Ghz no matter what settings I change, even when I increased the voltage
