CPU bottleneck hell.

[IBM_THINKPAD_R51]

So I have an HP Z820, and I am getting some pretty poor gaming performance, I game at 1440p.

Specs:

Dual Xeon E5-2667 V2 OR Dual Xeon E5-2697 V2

68GB FB-DIMM DDR3 in octa-channel (quad per cpu)

EVGA GTX 1070 SC Gaming

some SSD's and SAS drives

1280W Delta PSU (forgot what 80plus version it was.)

 

with the either CPU's, it will never turbo boost, it will always stay at base speeds no matter what

 

2667 v2 is supposed to turbo to 4GHz single core and 3.9GHz dual core...but its stays at 3.3GHz the entire time

 

the 2697 V2 is supposed to turbo to 3.5GHz single core and 3.4GHz dual core...but it stays at 3GHz the entire time.

 

in very rare cases, the GTX 1070 will be the bottleneck but 9 time out of 10 im cpu bottlenecked and the CPU's will never turbo....

 

 

ive tried to overclock with the intel extreme tuning utility but everything is greyed out....ive also tried to overclock with throttlestop but it will not do anything, i can underclock my cpu but it wont go over base speeds.

 

 

I really need help with this....i dont want to spend money on another platform like the HP Z840...i was going to wait for a gpu so i can run raytracing, but it wont help my performance otherwise.

Not gonna lie, it just sounds like you want something thats simply not what those CPUS were designed to do. I wouldnt bother with ray Tracing anything with that type of CPU.

 

Intel Extreeme utility is only available on platforms that support it, i dont think that board and cpu ever were supported by it.

Ensure that the required options for Turbo Boost are enabled in BIOS. These CPU's and platform are not capable of OC.

Well, it is a workstation with Intels workstation chipset C602, you simply can't overclock (more or less) either the with the chipset or the Xeon-CPU. That is also why Intel XTU doesn't work, there is no support for the CPU. The only XEON CPU that is supported in the current version is Intel® Xeon® W-3175X Processor (38.5M Cache, 3.10 GHz), hell it won't even work on the most older CPU:s then the latest couple of generations.

 

If it doesn't turbo-boost you need to check in the BIOS if that feature is disabled.

I can't remember what chipsets it is available on but there is a hack that will allow you to run all cores at the single boost clock speed.

 

Tech Yes City has more info on this. The issue is because your games are not using one core. Like, when they say for example one core can boost to 4ghz they mean when only one core is being used. As soon as you start using more it will go to those tables for the clocks. So basically you can't run the one core at 4ghz, then the rest as it seems to describe. There are set clock tables depending on how many cores are in use.

 

One thing the hack will not do is raise the power limits. So you will still be limited to the TDP of the CPU.

nice gpu, the rest seems ancient? i doubt its enough to play modern games, upgrading the gpu wouldn't really change that, in fact the gpu is already the best part, you need to update the rest - sorry i know that seems obvious, but you really need a better balanced system.

It is enabled, i just think that ANY amount of utilization on a core, even like 0.1% will make it boost that core too

There are some games that i play that happen to be multithreaded that completely destroy the GTX 1070

The E5-2697 V2 is boosting just fine. It has a base clock of 2.7GHz and a boost for 6+ cores of 3GHz. Nowadays, you're not going to see those higher boost speeds outside of synthetic tests because modern applications and games are multithreaded, which is a good thing for you considering that you are running a dual-socket setup. It would be bad if what you were doing was limited to a single thread. The extra 500MHz would not be worth losing a bunch of cores helping with the task.

 

The E5-2667 V2 should boost to 3.6GHz on 5+ cores. Are you sure you have Turbo Boost enabled on that machine and that you are not power or thermal constrained?

I have the Liquid cooler upgrade for the HP Z820 and the temps dont go over 75 degrees. Also Turbo Boost is enabled soooo
