If you have room temp wise put a tad more volts in it,say 1.03 under 5 mv extra.
See how it goes.

I don't the AC turned on atm here in the living room but even with low temps I still can't OC my card frown.gif it doesn't matter how much more voltage I add. I can't get past 928mhz core clock which only needs 1.0v to be stable.
and btw I have 2x 80mm silverstone fans on the side panel pointing directly to my video card so at full load temps are always great. I was able to OC my 8800 Ultra on this same pc and it overclocked like a champ

btw thanks for the help guys. + rep to all

edit:

lemme add somethign dunno if it means anything. when I'm folding even if I get it to 975mhz it will not hang but only when I'm running benchmarks and games it will crash. like what I said on my first post it will run fine for 20-30 seconds then display will turn off then gpu fan will be running at full speed

Wait a minute. Are you running the 560Ti with that 40" TV? That is a huge screen to run probably it will crash running benchmarks on that screen. Just wondering.

yes I am. it would make no difference because even if this is a 100" TV the resolution is still 1080p or 1920x1080 even smaller resolution than my 24" monitor on my sig rig which is 1920x1200.

even at low res benchmarks like 3dmark06 (which is 1280x1024) it is still crashing

I'm no pro look at my specs. I'm moving up to a 560Ti Twin Frozr or a 6950 soon but I actually had that in mind as long as you run in low resolutions but that is a darn huge screen hehe. Why don't you send it back if possible and get a Twin Frozr? Seems like a very reasonable video card. Out of the box overclocked and best cooling system. Just hoping if that is possible with you.

P.S. what does it mean anyway when your pc suddenly crashes and gpu fan speed is rev'ed up to 100%? I don't have much experience with nvidia cards. I'm really an amd/ati guy
could be a bios issue... could be something else...

and as far as your P.S...
sounds like you just found your alibi to trade your card in... that is a bad card.

this is actually an htpc/folding rig so I've been wanting to OC it more for more PPD

I doubt I can get a different card. I can prolly rma it for the same card but It's hard to make up a problem if it's working fine

but it doesn't do that when I'm st stock settings

oh just when you over clock it... my bad... but what that means is your card is heating up way fast, and shutting itself down. Sounds like the cooler isnt seated right... or something like that.

Well my card have the same problem, its from gigabyte tho, i got it to 920 cclock and have to pump as much as 1,100 v into it for it to be stable, I knew that not all gtx 560 hit 1 ghz but i thought i could atleast hit 950, but know, i doubt it.

Well i put it back on stock at 900 clock, becuz even at that clock its still run all my games on max without a sweat, and ill probably sli another one later next year, so no need to OC on my part.

All this blah blah from me just to tell you that your card is probably fine, even a gigabyte card with ultra durable material still have trouble hitting 1 ghz like mine =(.
As ROCK!

928 does seem a little low but I wouldn't say that "most 560 hit 950 without voltage" is true. If you think that temperatures might be a problem based on the fact that it shuts down without warning and then comes back up running at 100% fan speed then you might try resetting the cooler and reapplying some new thermal paste but it seems like you don't believe temps are the problem in which case I would guess that either your card is at it's limit as far as core speed goes (you could test this by seeing if the max allowable voltage in afterburner gives you stability any higher than 928 but I would only suggest that if you are sure temps are a problem), or it could in fact be a limitation of the palit bios as yourself and others seem to think.

EDIT: actually looking closer at pictures of your card it seems that your VRMs do not have any sort of cooling other than incidental airflow so in that case I would guess that that is why you are not getting any more stability when increasing voltage because it's actually your VRMs over heating first. In that case I would not recommend trying to max out the voltage in afterburner to see if that gives you more headroom because it appears that it's your VRMs holding you back. I would recommend some form of VRM cooling if you want to try going any higher but even that wouldn't be guaranteed, here are some that look like they would be appropriate if you cut some of them in half to cover all of your VRMs

Not really, my Gainward wouldn't do that even with additional voltage. Its because the palit doesn't have any VRM cooling (afaik) that you're crashing and the PCB is a pretty cheap design as opposed to Gigabyte or ASUS - But the main reason is the missing cooling on VRMs. I wouldn't push it if i were you, unless I want a dead card. Palit probably wont accept the RMA, they have a very strict policy :/. Its a really good card for small builds because its very small, but aside from that I would go for a different 560 if i was overclocking. Why use a GTX 560 for HTPC anyway? :/
