with modded BIOS?

Anyone know why my 2nd card voltage will not stay at 1.175 and goes up and down?? The core clock also is at 1319 at start and throttles like hell to low/mid/high 1200's.... Temp is low 60's...

1st cards voltage and clock stable...

This all while running 3d heaven

anyone else having their 670 drop voltage from 1.175v to 1.162v ?



iannotti, everything set to performance in nv control panel ? are you using afterburner or prec-x ?

Weird enough there wasn't any artifacts throughout heaven. Someone care enough or can explain it to me? 1 last thing, How is my result? Any feedback will be great. Cheers.smile.gif PX 160-550.docx 656k .docx file

Artifacts are most likely caused by your memory being clocked too high, but i have seen the GPU clock causing it as well. It is completely normal, and just means you hit your overclock limit tongue.gif. You got a fairly average overclock on that card, no reason to be disappointed tongue.gif

Some reason, it wouldn't let me adjust mem voltage?? It just reset back to 0 when I offset it.... I just playd with it a week ago and it worked... strange..
Now I'm getting about the same score as I did last night in Heaven 3D, BUT....GPU-Z is showing my clock to be much lower than last night... MSI AB graph shows a completely different max clock speed as GPU-Z......How silly is this?
Last Heaven3D was 2423 at max setting..Last night I was at around 2450...Gonna see how far I can push it in AB....
Yeah temps are up...Almost hit 70 on 1 card with the side panel off.... How the hell can you keep them cool?

In heaven i max out at around 71C (i don't get any throtlleing, so i don't care). I got a 180MM fan blowing straight at the GPU, along with 2 Gentle Typhoons in the front @ 1450rpm, so it is in no way starving for air :S. I am considering doing The Mod, since the card is pretty noisy :S

Thanks! That's a bit assuring as I don't have anything to compare it on tongue.gif. Is it true that if you OC your 670 mildly you can get a par performance as the 680?

Is the 2nd card running at full load?

You can indeed, but as soon as you overclock the 680, the gap stays the same tongue.gif

I found this thread pretty interesting, as it shows just how big a difference lies in the PCB alone, and what the 670 chip is actually capable of (it should be mentioned, that the 670 he got, was pretty damn nice):

wow, If what are you talking about is true, I'm quite disappointed that I only reach 1333 Mhz @1.3v

Maybe my search skills, but how you can enable the voltage monitoring on your afterburner? I search that feature on mine, but didn't found it.

My multimeter says 1.306 smile.gif
I got to 1359, i would love to do The Mod, and see if lowering the temperatures will allow me to go even higher (anything beyond +60 voltage doesen't allow me to go higher on my overclock, although it still adds more voltage, i fear that the GPU is very sensitive to high temperatures :S)
Just make sure you are using Afterburner 2.2.3, that is the only version that supports overvolting (later versions had it removed, and previous versions didn't support it).
If you are using the Twin Frozr cooler, you should hit very high temperatures, when overvolting on this card. If you are able to stay below 70C on air, you are probably not overvolted.

Yes, I am using 2.2.3, and Yes, I was doing it too, but the voltage monitoring didn't appear on the monitoring tab.

Maybe I should test it myself, to make sure my voltage is beyond 1.175v. I remember on the 670 PE thread, someone test his PE, and the voltage is not beyond 1.175v

and Yes, I always using 2.2.3 since that AB is the only one which is the best for the PE 670 card.
