My GTX 570

[mytrados]

Hia folks! I have the MSI gtx 570 twin frozr III and I'm in dire need of your help.

Core clock 770 Mhz
Memory 2000 Mhz

When it isn't overclocked I have temperatures ranging from:

Idle: 32-40 degrees celsius.
Load: 55-65 degrees celsius in MSI kombustor.

When I try to overclock it, it almost instantly buckles under and starts GPU throttling when using MSI kombustor, or I can often get crashes in the witcher 2 and Ghost recon future soldier (Yes I know the last game has had it's stability problems).

I was then curious of what's causing my card to crash or throttle, does anyone here have any feedback on the topic?
I would really like to overclock my GPU to squeeze out some extra power, but from what it looks it's running a bit unstable at times. So as I mentioned, please share your input on the topic and any solution will be tried =)

My system as it is now:

Motherboard = Asus Sabertooth P67
CPU = Intel core I5 2500K clocked to 4.5 Ghz
PSU = Corsair HX 850W plus silver modular
RAM = Corsair vengance 16 gb of 1600MHz
GPU = MSI gtx 570 twin frozr III

How far are you trying to overclock it at once? Sounds like you're jumping a bit too far to start with. Try just 10 MHz above stock and see if it is stable. Only do the core first; find your core's max then move on to memory.

If you haven't already done it, you should enable GPU voltage control in Afterburner. If you can't get a stable overclock even a little bit, try bumping voltage and then raising clocks. You'll need to use voltage to get further at some point anyway.

Once you get going...if your temps are still good you can flash your 570's bios to get it to go up to 1.2v (iirc, afterburner, once unlocked, gets you to about 1.1). If you want to go that route, search for NiBiTor if you want to mod your own or pm me...I made a bios for the same card as your's.

Hia guys! Thanks for the reply.

I've gone up about 10MHz each time, but it throttles right away. I've not touched the memory at all seeing as I've read that it could cause even more stability problems. I ran furmark now and in the stress test it doesn't down throttle, but it does down throttle in the benchmark test (No idea why).

I also tested out some new games to see if I got the same results there, and in Battleforge I got a black screen and then got the error message from windows. In Guild wars 2 on the other hand I don't have a single problem. And yeah running both at full graphics.

I've fiddles a bit with the voltage, and right now I'm on +43 on the core voltage, and +10 on both memory voltage and Aux voltage. Not experiencing any more stability though =/

Right now I'm playing guild wars 2 with a core clock of 900mhz, and shader clock at 1800mhz, and the memory clock is at a standard 2000Mhz.

Poke me back if I can supply you with any additional info =)

You need to increase cooling first, then voltage if you have headroom. What are your load gpu temps? You should set a custom fan profile so it provides more cooling (although it'll definitely get louder).

 

[mytrados]

The temps are 32-40 degrees C on idle (depending on room temp) and on load it varies from 65-75 depending on the game.
I just played ghost recon future soldier and it crashed, here is the dxdiag file. Hope I managed to do it right though. Just ran dxdiag right after the crash then saved it.

Sorry...I'm of no help in deciphering the file...clueless there :/

Temps seem good! Did you unlock msi afterburner? That'll give you a little more voltage (about 1.18 iirc).

 

[mytrados]

Aye I've unlocked the voltage control, but I don't get the the voltage number. I get +1 to + 150, so I don't know how much voltage I'm putting through.

 

[funsoul]

in msi afterburner...on the right...you should be able to see the voltage. iirc...stock is .975v so when you push the slider up to +150 your voltage is 1.125v. If you're at 75C load at 1.125v you're still fine (and could even add more voltage if you want). A modded bios can get you up to (again, iirc) 1.21v, the one I did takes it to 1.20.

 

[mytrados]

Cheers man! I'm at 1.031 volt right now, though I'm not sure if it's fluctuating or stable at 1.031.

 

[funsoul]

Cool. How are your load temps doing? Are you able to get a better overclock?

 

[mytrados]

Let's see... I did two stress tests, one in Furmark and the other in MSI kombustor. Both with 1920x1080 and 8x MSAA.

In Furmark I reached temps up to 69 degrees C, and in MSI kombustor I reached 67 degrees C. I did not experience any GPU throttling what so ever, but I'm not sure if this will apply when I launch a buggy, gpu heavy game such as Ghost recon future soldier. I've had stable runs in MSI kombustor before and then crashed in GRFS later.
This could be temperatures in the room fluctuating 5 degrees up or down, but I wouldn't think that would have that effect.

I'll run the game later on and see if it crashes or so, but I'm starting to get worried about the fact that it might be my PSU...

Cheers for the help so far!

 

[mytrados]

Damn it! I've jinxed it... I ran a benchmark 1080 preset in furmark now and it started to throttle like crazy...

 

[funsoul]

Try using afterburner instead of kombustor. Are you overclocking your cpu, too? Is it your 570 or cpu that's throttling? If you're overclocking the cpu, too...make sure you've found a nice, stable overclock there first.

For now...you might want to run the cpu at stock.
