Can't seem to OC my GTX 285 "FTW" cards

post #1 of 7
Thread Starter 
Allllright. I have two EVGA GTX 285 "FTW" edition cards, they come stock clocked at 702mhz core, 1584 Shader, and 1323 memory. I have two of these in SLi.... Both cards are watercooled with full-cover blocks, idling at 30-40C (highly dependent on ambient and system uptime) and load at no higher than 55*C on the hottest days

I've tried just setting the core to 740mhz and i don't get any artifacting with Furmark but when I game i notice that I tend to get a lot of crashing (IE: BFBC2.exe has stopped working, and so forth... hl2.exe has stopped working) causing games to crash to desktop

Voltage tuner does not seem to be available for this specific card so I really don't know what to do to get more performance out of these cards. I'm not one to turn down graphic settings (come on look at my rig man) so I would rather burn up the hardware and upgrade when needed. I'm avoiding an upgrade right now (reason for attempting to OC the card) because I'm waiting on my new case to finish before changing anything.

Halp?

Are you using Evga precision? I know with my 275 FTW I don't think I ever saw an option to change voltage there. Have you tried MSI Afterburner? If you haven't, see if you can adjust the voltage with the 2.1 Beta version. If not, then I don't know what to say

I am using EVGA Precision - they have a separate tool for voltage - cleverly named EVGA voltage tuner. It only supports specific product numbers, my cards are not on that list.

MSI afterburner is the same thing - they're both based off of the Riva Tuner engine, IIRC

FTW cards are already highly clocked, you will get very little or nothing at all from them. My 285 cannot hit FTW clocks for example, even on the core.

There is no voltage control on those cards, but they should overclock decently. I had a 285 FTW, on stock cooling/stock voltage it would bench at ~760/1700/1400 pretty comfortably. I didn't use it for extended periods though except in tri sli.
Are the cards revisiion 1 or revision 2? There is a very easy volt mod that can be done on rev.1 cards only needing conductive ink.

I really don't like hard volt mods due to warranty purposes and I won't be keeping them long, however I'm still interested in such a thing. No idea what Rev. they are.. most likely 1 since I got them early, but they are an RMA pair.

I can't really get my cards past 740 yet, still testing water on OC's but hopefully it gets better.
