Gainward 260GTX overclock
- Thread starter dokko
- Start date
Hi,
When i press the test (using the EXPERTtool), nothing really happens, it looks like its about to load something, completes the load then nothing.
Is that it, for the test i mean? Is it safe to play?
Edit: Was having a look on rivatune, where do you overclock on it, i cannot see any options?
mine clocked to 700core 1500 shader and 1200 (2.4ghz) ram.
the ram clock is a given since the ram is 0.8ns samsung stuff so your guaranteed 1.2ghz on the ram no problem.
i used gpu tool to do some testing with and 735mhz core caused screen to black out.
going beyond 1500 shader speed is not easy. also use the new occt gpu stress tester tool its does auto error checking so its very simple to overclock with.
also expertool is awsome its really simple to use and you can play around with fan speeds as well.

no the blackout was not caused by expertool it was caused by gputool.
i used gpu tool to do automatic overclocking, so it runs and clocks my card up by 5mhz and does artifact testing then clocks up more and more and more it got to 735 on the core and screen blacked out. so i found the limit of my core which is gonna be below 735mhz.
i currently doing some more oc testing now since this thread has made me want to find out how high my card will clock up to. will post updates later on.

GPU Tool currently doesn't find the core clock very well on the 200 series cards. Tho it does give you an indication of the top end of the core - the real stable clock is approx 20Mhz lower IMO. Usually it either blacks out or goes corrupt and keeps lowering the core clock without any results.
Also its max shader clock detection is a bit enthusiastic I think - the real stable value is probably 54MHz lower.

thats the tool in the link above im using to stress test with now. after the reading up the occt forum it turns out that its better to run the tester in fullscreen mode. i just did that and its picked up errors in fullscreen mode where it never did in windowed mode.
fiddling around with it now but its deffo the shader clock which seems to be too high. gonna do some testing with it now but i rekon shader clock will be going down by atleast 50mhz to get fully stable. will post updates.

I went to 750 core before I noticed artifacts in crysis bench, so I stuck it on 700/1470/1100, nice round numbers lol.
I read that you should always un-lock shaders as the the core can go much higher whereas shaders get stuck around 1500
p.s I didn't mess with the fan speeds, my 260 is quiet and I like it that way, really impressed with 260

yep roff your correct, i used rivatuner here since the shaderclock is a real tricky git to oc properly. try a 10mhz oc and it shoots up by 54mhz so its real tricky to know what its actual clock rate is without rivatuner.
my card been running occt artifact tester now for 40 mins and no errors detected.
clocks are 700core 1200ram and 1440 shader. the 1440 shader is the actual speed shown by rivatuner monitoring.
not a spectacular oc but any free performance is always welcomed.
oh peak temp reached on gpu is 75c but thats using my custom fan profile. its making a real racket.

knowing my luck out of all those 216 stream processors its probably just 1 of them that doesnt like going over 1440mhz where as the other 215 are happy with 1550mhz lol
haha yeah, but like you said, any free performance is such a bonus.
I never overclocked before but now I have, pre-overclocked cards look like such a rip-off
good stuff. what sort of temps do you guys get??
without my modded fan profile i was getting around 83c max load.
one thing iv noticed about this card is that case cooling is very important. if i remove my front fan intake dust filter while the card is stressing i can see the temps drop and the noise drop considerably too.
may fiddle around with some ducting to the card later on too.

With a modified fan profile I max out at 75-76C on extreme stress tests and 68C in normal gaming situations.
Infact the second card, which is 55nm (the top card is 65) never really goes above 60C - the top card also has the NB venting on it
which makes it even warmer - I prolly should switch those 2 around but its a bit of an effort.
