460 gtx voltage problem

post #1 of 9
Thread Starter 
Greetings all have a slight problem that I havent been able to find any sort of answer for so Im hoping someone here will be able to help me out.

Started out with a evga 460 gtx 768mb and recently bought a second. Been pretty happy with the additional power in sli but, the problem Im now having though is the second card rarely uses the assigned voltage. Im running msi afterburner and have them both overclocked to 850/1700/1900 and the voltage at .987 but the voltage on the second regularly drops to .888 or if my voltage is set at .975 it regularly sits at .875 .

I recently upgraded my PSU from a 600 watt to this corsair 850 watt so I wouldnt have a problem with power.

As this item was bought used I cant return it and I dont think I can send it to the manufacturer without original receipt. Any ideas what the problem or more-so some sort of solution?

Did you select "use constant voltage" in MSI Afterburner?

Don't quote me on this, but if I remeber rightmy GTX 460 would use 1.1v

The first thing you should do is remove both cards, and test the used GPU you just got. also, what brand make and model are the cards? that might make a diff too.

Both EVGA 460's although my first is the "super-clocked" edition while the second one I bought is just their standard performance boost edition. I have them both clocked the same since that was really the only difference in them I could find. I wasnt able to find out specifically what the stock voltage is on the one Im having a problem with (perf boost edtn) but since it responds to whatever voltage I set it to just regularly dips -0.100 to whatever I set it as I'm rather confused.

I've tried using it as just a single card and get the same results poke.gif


PS- Stock voltage for most 460s Ive seen is around .975

As I said, don't quote me:) I have an SSC EVGA 460 sitting on my desk right now, same clocks as your's are. What mobo do you have these guys plugged into? and good luck with EVGA is you are not the original buyer of the card:(

Motherboard is Asus Sabertooth 990FX, and yea EVGA is real strict about their support and unless you have original receipt its pretty much impossible to get them to help you out...
