What's a safe volt for the GTX 260? - Overclock.net

Admiral Mudkipz · 08-28-09

Yea, I'm preparing to volt mod my GTX 260. I was wondering if you guys can give me a safe, but reasonable volt, meaning that it has to be stable, but not with the addition of extremely high temperatures.

I was able to hit 733/1539/1250 with no volt modding, which is actually incredibly good. However, I want to boost up all my clocks a bit more, so apparently, volt modding was the only thing I could do.

Temperatures with the current clocks are:
39*C idle
61*C load
50*C folding

My temperatures are low because my computer is in a basement that's always cool year-round, and I keep my GTX 260 fan on at 100% at all times. I don't mind the noise because I already have 8 high speed fans on my radiator anyway, so I've gotten used to it.

Volts are 1.0625V. I don't know a safe level of voltage yet because this is my first time volt modding a GPU. That's where you guys come in.

I will also include a screenshot of all my clocks/voltage/temperatures.

Thanks in advance.

not really sure about the gtx 260 sorry m8 but have you seen this link?:
http://www.xtremesystems.org/forums/...d.php?t=215521 perhaps you
can get some info from that

also gputool can do some voltmodding
i know.

Yea, thanks. I will be using GPUTool to do my voltage modding. I just needed a guide for the safest volts, and I think you provided me with a good one. Thanks!

EDIT: Actually GPUTool seems to be as easy as a little slide of the bar, without all the hexadecimals and thinking required

not absolutely sure but from what i can read 1.37v seem to be the max safest. but like with cpu overclocking 1.40-1.55v+ are not uncommon. 1.6v can properly be done, 1.7v would be stupid

so it's a lot like overvolting a cpu/nb although i believe a gpu can take just a little more beating

Well, what I plan on doing is keeping my clocks right now, but pushing the volts until my GPU is unstable on Furmark.

Then...I start overclocking my GPU.

heh well ye

that would be a way to find your max voltage

sry can't really help u. my 4870 havent got a soft modable voltage
regulator.

why would u want to up your voltage isnt your current clocks stable enough??

They are stable. But I want higher clocks.

oh yeah got it now

lol for a minut i thought you just were gonna
up the volt without a plan

edit: most be slow today just read the last line on post #5

edit2: your card should be able to handle 70-80c+ temps..90c will properly shorten
it's life.100-130c in extreme situations. but then again you won't be running furmark for years.

Alright, thanks again for the help. I keep my fan on 100%, so 70-80C probably won't be happening unless I seriously up the volt.

Anymore recommendations people?
