Phenom II X4 965 BE @ 4.08GHz, voltages ok? - Page 2

post #11 of 15
CnQ off normally does nothing to improve stability, just so you know
For the sake of power saving, chip longetivity, and user benefit, leave it on. Turning it off is a common misconception. I run my 4Ghz OC with CnQ on.

Ouch... I guess I will just count my blessings that I got a nice chip... I guess it doesn't really matter much on your end though since your temps are kept in such good ranges with the H100. So just give it whatever voltage it wants and be happy with it.

I'm testing it at 1.4625v right now, and have updated a couple of settings, but I don't know if I will be keeping it here permanently; it all depends on the results:

CPU Settings are:

Running Speed: 4080MHz
Bus speed: 240MHz
Multiplier: x17
CPU-NB: 2640MHz (x11 multi, up from 2400MHz)
VCore: 1.4625v (down from 1.4875v)
CPU-NB volts: 1.2875v (auto setting led to crashes)
CPU VDDA volts: 2.60v ({poor} compensation for vdroop)

Cool N Quiet Disabled
ACC Enabled, +4% (whatever that does is beyond me, but it's been suggested on a few forums)

HT Link Speed: 1920MHz (x8 multi, down from 2400MHz)
HT Link Width: 16 bit
HT Link Volts: Auto

RAM settings are the same, I know that the RAM is 100% stable at it's current overclock.

Anyway, I'm getting ready to run 10 passes of Intel Burn Test, and if it passes, an overnight Prime95 Blend Test. If stable, I will keep everything where it's at and call it good; been f***ing with this for way too long.
Hey man. Noticed you dont know what Acc is for. It basicaly Just Calbrates the proccessors, Lets say you got a high overclock. When your up close or go over your Overclocking wall. atleast 1 core can Often Fall behind Thus slowing down the rest. Now If you find which of the cores are falling behind you can use ACC to + 2,+4,+6,ect to bring it up with the others while also benificial to -2,-4,-6, ect the others Achieves better overclocks x) hope i help yea

Oh yea 1 more thing. All Chips are different some might need 1 core pushed up while others need back. So if someone Needed + 4% on 1 core doesnt mean at all the rest do too. catch the drift

Awesome man, thanks for that info.

After running P95 all night without errors, I tweaked my setup a little bit more to lower temps/voltages and take into account your guys' suggestions.

Currently getting ready to start a round of P95 tests @:

Running Speed: 4080MHz
Bus Speed: 240MHz
Multiplier: x17
CPU-NB: 2640MHz
CPU-NB v: 1.35v (third processor core always gets rounding error if CPU-NB voltage is too low, this continued to happen last night until raising it to 1.35v)
CPU VCore: 1.4875v, down from 1.5v (noticed that @ 1.5v, under load the voltage would drop down to +/-1.4875v anyway, so I just lowered it to match that)
CPU VDDA: 2.80v (to allow the CPU to overvolt to ~1.5v when idling, so that high loads bring it back down to ~1.4.75v-1.4875v)


CNQ: Enabled per suggestion
ACC: Enabled, Core 0: -2%, Core 1: -2%, Core 2: +4%, Core 3: +2% (3rd and 4th cores fall behind in P95 with ACC off)

This setup has already passed an initial bank of Intel Burn Test. I did 10 runs at the Standard Stress level. Will test with Prime95 all day while I'm not home, and if the results are good, will run CPU-Z validation and post my desktop

Bah. It still isn't stable, and I'm not going to push my voltages any higher than they already are.

I revised a few things due to memory related BSOD's.

Bus: 250MHz
Multi: x16
VCore: 1.5v
CPU-NB: 2500MHz
CPU-NB v: 1.325v
VDDA: Auto

HT Link: 2000MHz
HT Width: 16-bit
HT v: Auto

DRAM Frequency: 1333MHz
Timings: 7-7-7-23-31 2t
Voltage: 1.5v

CNQ and C1E Enabled
ACC: Core 0: 0%, Core 1: +2%, Core 2: +6%, Core 3: +4%

This overclock is 100% stable so I'm just gonna stay here, I don't think I can go any higher due to either the CPU, the RAM or the mobo. Either way I managed to get an extra 11-13 GFlops out of my chip. Thanks for all the help though I learned a few things that I was previously unaware of.
