i7 920 on ASRock x58 Extreme: help getting from 3.8GHz to 4GHz

post #1 of 70
Thread Starter 
I have successfully OCed my i7 920 to 3.8GHz (24h prime95 stable, 15h Linx). Temps are OK, 83C max.
My settings:
200x19
vCore: 1.3v
VTT: 1.34v
CPU PLL: 1.82
HT: Yes
CStates, Throttling, Speedstepping: Yes. I wan't to keep these and HT on.
Everything else is at stock.

If I set it to 200x20 I can't even boot.
191x21 and vCore at 1.35v I can boot, but I get a BSOD after <1h of Linx.

I've tried playing with the other voltages (CPU PLL, IOH, ICH, etc) but I haven't been able to get it stable, and I haven't kept a proper log, so I'm ready to start from scratch.

Any help is appreciated smile.gif

Try increasing CPU PLL, ICH and IOH, check this, its all in here.

Try these settings out. I'm assuming this is a D0, so you may need to make adjustments if it's a C0:

Ai Overclock Tuner : Manual
CPU Ratio Setting : 21
Intel SpeedStep Tech: Disabled
Intel Turbo Mode Tech isabled
Bclk Frequency: 191
PCIE Frequency: 101
DRAM Frequency: DDR3-1528Mhz
UNCLK Frequency: 3056Mhz
QPI Link Data Rate: 6876 MT/s
CPU Voltage: 1.325v
CPU PLL Voltage :1.88v
QPI/DRAM Core Voltage :1.35v
IOH Voltage: 1.18v
IOH PCIE Voltage :Auto
ICH Voltage :1.1v
ICH PCIE Voltage: Auto
DRAM Bus Voltage: 1.64v

You might also try 211x19 to get your RAM running at 1688Mhz.

Just explain a thing: u should disable speedstep, and HT....and try make the OC stable.
after some time of prime95, you may get them able able again.

The thing is I'd rather be at 3.8GHz w/ all that stuff than 4GHz without, so I'm shooting for getting it stable with all that, or not.

@everyone else: thank's for the replies. I'll reread (I had read it before, but forgot to come back to it) that thread, and try those settings. I'll leave it testing throughout the night, I'll report back tomorrow (unless I smell smoke or something, lol)

What I've figured out:
x20 multi sucks on my CPU: with 211x19 or 191x21 I can boot windows, but with 200x20 I just can't, no matter what settings.
IOH, ICH, CPU PLL, etc don't do anything for me: I tried them one by one, together, and in pairs, and none of them helped me.
1.34v VTT is the right point for 3.8GHz, and 1.41v for 4GHz (based on the BSOD meanings of the thread that Darren linked)

The stablest (1-4m Linx) I got was 191x21 @ 1.35< vcore (i.e., I tried up to 1.4v, and it didn't help), 1.34v VTT, 1.82v CPU PLL, evereything else at stock (voltage wise, I disabled spread spectrum, set QPI to the lowest multi, and adjusted RAM settings).

Even though I think it can be quite challenging overclocking with the power saving features enabled, I'm sure your goal can be achieved.

One thing that will help is to manually set as many options in the BIOS as you can. Especially, your RAM settings (DRAM Voltage: 1.600V, DRAM tCL: 8, DRAM tRCD: 8, DRAM tRP: 8, DRAM tRAS: 24, DRAM Command Rate: 2T).

Read through this guide, and see what progress you can make.

Then, come back and post your latest settings. If you encountered a BSOD during stress testing, post that error code, and I'll see if I can point you in the right direction.

Note: Try not to let your load temps get any higher.

typical for bloomfields that 20 multiplier is crazy.

my tip. loose timings on ram, or if oced, set to original clocks or as near as possible. or even try to lower them below the rated clocks for finding your way for 4.0 GHz. memory overclock got influence on cpu overcklock. try to push your pci-e clock for 101 or more.

check your vrm cooler. if you will find that all mosfets are imprinted on thermalpad its ok, but when one is not, you should be carefull and dont try to oc your cpu.

one more thing. D0? or C0?

My latest settings:
Everything set manually to stock. IEST, C1E and C-States enabled.
VTT: 1.34.
191x21.
@1.3625v vcore: temps get up to 88C, computer shut down after 5m of Linx.
@1.5v vcore: 3B BSOD
Now testing 1.5625 (I think it was) vcore.

EDIT: that was 1.3625v, not 1.625v, LOL.
