GTX 400 Overclocking/Modding Thread - Page 84

post #831 of 926
It could be triggering an OVP or OCP (Over Volt Protection) but I am not really sure, the Giga SOC series is designed differently than the reference card so I dont know what they put on it for protection.

I wouldnt be too worried about it tho, I doubt the added 0013mV would add all that much performance difference..

Curious if you have tried 1210 or 1212 rather than 1213?

Did that and everything was just fine except for 1213mV. I think it might be a protection thing. I'll go and check out the BIOS to see.

The 470 can be hard modded to get past the protection, but as far as I know the most we can do via bios is 1213, which may or may not be the actual voltage.

Whenever making voltage adjustments you should always use a DMM (Digital Multi Meeter) to test the settings.
You can pick one up at Radio shack for $20 if your here in the states, otherwise look at you local electronics store.

My card does 825/1650 @ 1100, but even if I push it to 1213 it will crash bench tests any higher, tried 850/1700 @ 1200 and up....

Hello I have a asus 480 not OCed yet. It has the stock fan. Can someone walk me through with a stable OC settings ?

Do i have to flash the bios ? Because i cant see V setting in MSI afterburner.

So what gives?
I noticed with my reference 480s as soon as I go over 1.2V it feeds more voltage than set, for example at 1.2V set in afterburner the DMM read 1.22V (going from memory, may not be exact), at 1.213 went up to 1.26v or so, I do remember setting 1.25V & the DMM had it at 1.35V actual.
Probably just a bit too much V for the cooling.

You have to unlock voltage control in the afterburner settings, you probably won't have to flash the bios to max the card on the stock cooler.

What if i want to go up to 1.2 V ?
post #837 of 926
For 1.2V you would have to edit & flash the bios, you would probably need some aftermarket air or water cooling to go there though, heat will likely be a limit before you get up to 1.2V.

Unless you are in Antarctica, heat will limit you before you can use anywhere near that voltage on stock. If you can't find a decent aftermarket air cooler (there are only 3 that I know of) you could;
A. Change the thermal paste on the GPU itself. I lost about 5C under load doing mine.
B. Find an EVGA back plate. Though difficult to locate, you could easily loose about 10C off your load temps with this.
and
C. Arrange the fans in your case so they point directly at the cards.

Hope this helps! Good luck!

I hit 800/1600 @ 1050 on the stock cooler, but would see temps in the 80's in any demanding game...

The VF3000F has done wonders for me, temps are in the mid 60's most of the time, I have noticed Dirt 3 pushes me into the 70's at times. But thats about the max at settings in my sig..

Probably just a bit too much V for the cooling.
Well, the only reason why I wouldn't suspect that is because my system gives out immediately after setting the voltage to 1.213v (I hit "Apply" and my screen goes blank). However, I'm pretty satisfied with my OC for the most part, and after looking into the BIOS I figured it wasn't worth the effort for just an extra 0.013v. Thanks for that tidbit of info though, I never even thought that I might be sending more voltage than what Afterburner is saying.
