Palit gtx 560 Ti OC'ing problem - Page 3

post #21 of 30
That crash sounds like the graphics driver crashing and no card is guaranteed to OC, youre just lucky or your not, try to push more volts at a temperature you feel good with.

As for when your system hangs: does it eventually blue screen or reboot? If I hang an OC, the screen will freeze for about 2 minutes then the monitor goes to no detect, followed in a few seconds by the desktop coming up with a 'system detected driver hang' message, at which time all seems 'normal' though no ramped up gpu fan ever occurs. The reality is that your 560 is probably a weak overclocker, it's a bummer but it happens (at least you're not the only one). My 560 is so so; I can run msi kombuster (essentially furmark) at 975mhz at stock voltages with no problem. Otherwise if I'm stress testing using 3dmark11, my best stable stock voltage OC is 925mhz . I can hit a solid 960mhz with 1.06v, but anything beyond that is eventually unstable regardess of voltage.

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? :/
prolly the lack of vrm cooling is the reason. rma is different here in Manila. we just return it to the shops where we bought it and the shops return it to the local distributors. I've been a long time customer so rma may be a lot easier for me. I'll just say that sometimes my card randomly crashes even at stock settings and tried it at my 2 computers.

folding@home. gtx 560 Ti = 16-17k PPD

I've come to the conclusion that it just plainly sucked at overclocking. I'll try me best to get it rma'd. thanks everyone, +reps

If it's a big hassle for either you or the store to get it RMA'd it might not be worth it seeing as you can only exchange it for the same model which will still have the same limitation of no VRM cooling. I wouldn't expect more than maybe 20 MHz better out of a new card if your lucky and possibly worse if your unlucky. Like I mentioned above if you really want to get more out of the card either additional VRM heatsinks or a different card entirely would be the best bet but still not guaranteed. Hope this or my previous post helped.

what will 30 mhz give you? 1-2fps?

you won't be able to tell the difference.

60mhz shader clock would be a fair boost in folding@home

You're lucky - mine is unstable even at the factory-overclock of 900Mhz. Playing a number of games (Modern Warfare 2, Bioshock 2, Crysis 2 MP Demo), I was getting black-screens/freezes every 5 minutes. Tried uninstalling/cleaning/reinstalling drivers without success, then thought of using nVidia Inspector to lower the clock from 900Mhz to 850Mhz. Touch wood, but I could playing Bioshock 2 for an hour without any problem.

my card gigabyte gtx 560 ti oc
using msi afterburner
stock =1000mv
coreclock =900
shader =1800
memory clock =2004
fan speed = around 80% to 85% when running crysis
Room temp = 26'c

play crysis at ( advance setting ) - fps 55 minimum / heat bettween 70'c to 73'c / smooth + never crush
When set crysis (hardcore setting ) - all the same except heat . 74 to 77 around now

Oc to 950 require 1.025 volt atleast for me and which is quite stable except heat around 78'C . Since i never experience gpu above 70'c heat I rather use stock 900 with stock voltage Hope my experience will help someone
forgive my bad english ^^

My card's stock voltage is 0.987 and is a pre overclocked card from 822mhz to 900mhz core clock. I can't OC it much. I'm really struggling on getting it stable even with only 928mhz clock speed.
Jeez, you're lucky. I had to underclock my one to get it stable; otherwise I was getting black-screens in many games.
