Trying to Push Xeon X5675 Past 4.3GHz

Too high QPI (or too low voltage on ICH/QPI).

Hmmm okay, I've kept the QPI as low as possible on each one. What should I raise the voltages to?

agent_x007 · Jul 16, 2017

If you can't do Slow mode on QPI, you need to up the ICH voltage at least.

Is there a way to know what the auto ICH voltage is set to?

agent_x007 · Jul 16, 2017

Sure. In ASUS it's lowest value you can set (1,1V)
But in some other boards, default value can be a bit higher (1,2-1,25V).
For 6,8GT/s QPI I would go 1,3V+ and see what it does.

RickyRozay · Jul 16, 2017

I'm guessing I'm near to the limit, I put all these voltages but it didn't want to play any more

Any last suggestions, or should I call it a day?

I don't really understand these results. It seems like everything less than a 25x multi just gets a big fuck you.

There is not too much to understand, it's all about if the CPU is a good overclockable one or not and board quality.

agent_x007 · Jul 16, 2017

UCLK = 3688MHz (max.), lower it below 3,6GHz if you still have stability problems.
CPU PLL = 1,9V

BSOD 3688MHz

Take it from me

It's not the CPU

Remember me going through this some time back and everyone thought it was my CPU

agent_x007 · Jul 16, 2017

Kinda high PLL but ok use 2,0V.
Did you lower the BCLK below 3500MHz ?
Up voltage on QPI to 1,325V

BSOD 3504MHz too!

Tried also 2.0v PLL and still BSOD.

agent_x007 · Jul 16, 2017

OK. Change DRAM Frequency to a lower one (1656MHz I think).

Just to add, when I put UCLK to 3872MHz, and change all voltages to Auto (except CPU Vcore 1.35v) it boots to Windows without BSOD and seems fine...

Weird... anyway

[DRAM] 1476MHz
[UCLK] 3135MHz

BSOD

agent_x007 · Jul 16, 2017

Really ?
That's interesting... wish you would know what that AUTO voltages are.

EarthDog · Jul 16, 2017

Why not check them and find out....

RickyRozay · Jul 16, 2017

I think I'll give up here, it's clearly very unstable above 4.5GHz!

Thank you very much for all your help

and everybody else involved too

How?

agent_x007 · Jul 16, 2017

Check sensors in HWMonitor.

Okay I got HWmonitor, which sensors am I looking at?

Ignore the high idle temps, I used regedit to disable the idle state in Windows cos it makes coil whine if I don't. My load temps are only like 10c above idle.

agent_x007 · Jul 16, 2017

You don't have them

HWInfo is also a good program to check, but I think it will show the same values :/

FilipM · Jul 16, 2017

QPI voltage, set manually, use max limit of 1.35 on that.

Norton · Jul 16, 2017

The IMC on the chip may be holding you back. Drop down to one stick of ram and try your overclocks again.

EDIT- found this online tool also (haven't tried it):

Do me a favor

Clock it to where you think it's stable

Run Cinebench R15 and after it finishes, screen shot Hwinfo

I want to see if the CPU is thermal caping

What cooler are you using as well ?

Noctua NH D-14

For some reason the multi drops from 25, to 23, when under load... any ideas? Voltage appears to stay the same

RickyRozay · Jul 16, 2017

So I flashed my board to a P6T Workstation Pro. Basically it turns out the P6T Deluxe has a TDP throttle as @Durvelle27 mentioned earlier.

Now I can keep my multi locked at 25, and it doesn't drop under load!

The bad news is, now that I'm seeing the "genuine" performance, it's only stable at 4.2GHz. Anything higher gives me a BSOD under load... kind of super disappointed :/
