ASrock 880G Extreme 3, Extreme voltage drop.

[Sodapopjones]

I'm not quite understanding whats going on, regardless of stock speeds on my 1055T or OC'ed to 3.8ghz, after several hours I will lose voltages.

I have the voltage set to 1.38, runs 1.38 under load prime95 even for 6-8 hours, I will come back and see my voltage drop to 1.24 and obviously stuck at the 800-900mhz range.

I'm pretty sure its not my PSU, the 12v rail sits solid at 12.77 under load with no fluctuations.

My guess is its the voltage regulator on the board, after several resets it comes back to the voltage I set and not 1.24...

I have tried the bios 1.0, 1.2 and 1.4, 1.4 seems to be the best as far as stability atm...

I'm just curious what do you guys think?

3.8ghz with no issues...just the insane volt drop.

is turbo kicking in at all, and why still use prime why not somehting better like occt or lineX

[PatRaceTin]

does it has loadline option in BIOS

[crazydiamond]

whats wrong with prime zanzabar? i always felt prime blend was one of best all around stability tests..

to OP, are cool & quiet, c1e, & turbo all disabled in bios? also check to see that windows is set to high performance not powersaving mode. if all this is how u have it then not sure, maybe bios?

If you have 800-900Mhz frecuency, sure you have cool & quiet activated, dezactivated it. And 6-8 hours it's much, 2 hours is enough. X6 consumes very much power, in overclocking is above i7 860/930.
You use the stock cooler(profile picture?), what temperatures you have, the vdroop and the drop of frecuency appears in prime at 100% load, than we might have an X6 throttle...or after stopping prime?
And even if you have good temperatures in real temp, the processor is heating and think otherwise. Touch the heatpipes from cooler under load if they are hot than you have higher temperatures than shown.

Does this voltage behaviour cause any instability ?

[Lightman]

I'm sure it's C'n'Q!
Low power state - 1.25V stock for 1090T
Normal power state - 1.3V to 1.35V varies between batches
Turbo power state - 1.475V

So what OP is observing is normal, but if C'n'Q is disabled in BIOS and this is still happening then simply wait for better BIOS.

One suggestion - start AOD and click on that green dot in top right corner, it will change to one with red ring, you CPU will not go to low power state and stay in Normal/Turbo only

Yes, they're disabled and windows is running under "ASRock OC Tuner"... not power saver or balanced.

No it just drops my clock speed down to 800-900mhz with a multi of 4...

This makes sense, maybe I can snag a beta bios from ASrock, I dig the 880G board.

I'm going to sound like a "Ratard" but AOD? It is late lol...

also, you could try enabling all the power saving features in BIOS, then in windows set the power scheme to always be at 100% clocks/volts.

Sounds to me that CPU starts throttling due to too much heat. When the multiplier drops down to 4x, I bet the vcore also goes very low. And this happens repeatedly in about 5-10min cycles. You know, when you are stressing your CPU there's no point that it should lower it's clocks while working. When your CPU idles, then it should go lower.

I've got this thing happening in less than 60'C temps. With lowering frequency a little (100-150MHz) and perhaps VCore also, you won't see your CPU going down to 4x multiplier anymore.


Get better cooling or lower your clocks.

OHH, ok thanks man!

It does this at stock speeds, 0 load at 38 degrees lol....

i dont like prime as it dosnt get the cpu as hot, and since i have a liquid system with a cpu/gpu loop, ii normally use the occt psu test as it loads the gpu with the occt test and cpu with lineX

and +1 i would guess its bios.

I think it is a BUG in the BIOS, it lests the C&Q options on...

If the board doesnt BSOD, then there is no problem...

[mäggäri]

There IS a problem if it drops the multiplier to 4x under constant stress. Or you do guys press brake pedal while accelerating ? :--D

It doesn't BSOD, its just annoying

its cool and quiet or turbo kicking in, when something goes and reloads work units the load goes down and when that happens im guessing that the turbo is kicking in or cool and quiet is kicking in. it wont have any real ill effects its just annoying. if u did get 0.1V droop i would expect a BSOD but if it is not then dont worry

as sod said
