(1st OC) Help evaluate my 970@4ghz

post #1 of 6
Thread Starter 
After a few weeks of testing I think I have found my stable comfort zone on my first overclock....but I've been having a few strange issues, so I wanted to run some things by you guys.



HT on
LLC turned off
Turbo off
All power saving features off

Mult @ 25
[BCLK] 160
[CPU Voltage] 1.26875
[DRAM Bus Voltage] 1.5v
[QPI] 1.26875
CPU PLL 1.8
ICH 1.1

12gb gskill 3x4 @1600 -Tried to get closet to memory stock

Prime95 blend for 22 Hours No errors + 25 passes of intel burn test

My temps seem too high with my Noctua NH-D14 (fans @ 900rpm) :*( The nocuta is the loudest thing in my case right now, whoever said it was quiet was lying. -Thing is a freakin wind tunnel.
33c Idle average
64c Load average
OCCT linpack got to 75c!


1) What can I do better at this point? Everything is stable.
-Does it matter that my ram is @ 1.5v Would raising it help stability?

2) Here are some weird problems:

-Windows and cinebench report my old OC @ 3.8ghz and wont change no matter what i do
-Three different monitoring programs report my voltage wrong.
-Hardware monitor in bios reports voltage wrong from manual setting, (cleared cmos and installed new bios rev, and it reports lower voltage by about .025-.05v
-Only Asus TurboV shows my true voltage
-During one of my earlier OC trials I had my vcore and QPI @ 1.24. I ran 20 hours of prime95 and it looked awesome, but then OCCT linpack errored after 10min..thought that was strange.

sometimes a higher mult,can cause instability. I recommend 20x200.
200bclk= higher RAM clocks, so u shall raise qpi voltage (only if it become necessary)

Your system could be throttling the multi under load back to the stock 24x, hence it seems you're at 3.8Ghz. I'd suggest enabling LLC to keep a handle on the voltage droop you're experiencing. If LLC doesn't help, it may be worth monitoring the voltage ripple coming out of your PSU, it may be a mechanical problem.

It looks like my voltage is dropping about .04v under load.
I thought enabling LLC was a bad thing?
Could it be the PSU? All my rails seem good under load (thats why i spent so much on this seasonic x750 gold unit ....but maybe its wack :*(

Load Line Calibration is designed to lock your voltage right around what you set it in BIOS. Its function is to remove vDroop, the exact phenomena you're experiencing here.

Update
Changed to 200x20
Enabled LLC
Just for a test i lowered the vcore to 1.225
Left everything else the same ram @1600

-My vdroop is gone, no spiking.
-Prime95 has been running for almost 10 hours and no errors. Ill keep in on throughout the day.
-My temps are about 5c higher though.
-Windows is now reading my cpu @ 4ghz!

I was under the impression that higher fsb would require more voltage! Im thinking maybe I should drop it even lower, or go revisit my 25x160 with LLC on to see if its stable!
