GTX 460 Max overclock

post #1 of 23
Thread Starter 
Sup yall!

Ok, so this is the story...

When I bought my GTX460 the box had a large badge saying 'Voltage tweak!' and well you can imagine my first impressions... "no way I'm going to do any voltage changes on this baby..." lol. Well I did a little research and found that there really isnt anything to worry about changing the voltage on the GTX460, as the max limit in MSI Afterbuner is safe.

So this morning I did a little overclocking on it to see how high I could go...
Here are my results...
Overclock.jpg
885MHZ! and 2000MHZ! on the memory! total ownage if you ask me.
It's 10 minutes Furmark stable and seems to run smoothly in Bad Company 2 at max settings.
I threw in my cpu clock too, hehe smile.gif

Stock voltage on the card is 0.975v and I have raised it to 1.035v to achieve 885mhz, it also maxes out at 74c at full load.
It's an Asus Geforce gtx460 1gb version.

The max that MSI Afterburner allows is 1.087v, I'm pretty sure I could get it to 900mhz although I dont want to push my luck.

One thing I noticed about this card while overclocking, is that it never artifacts? Instead when it becomes unstable it simply crashes furmark, BSOD's or locks up. This makes it slightly harder to interperate weather the card is running stable kookoo.gif

Also the card makes an almighty whining noise from the onboard capacitors when it's under full load, this baby is pulling more than 300w at 885mhz!

Really happy with the results and would love to know what you think cheers.gif

I had mine at 900MHz, but I don't remember the specs I had it at. I've got a Sparkle GTX 460 1GB.

I ended up getting a messed up driver and it just threw up my GPU, had to uninstall and reinstall, and I lost my GPU specs for it's OC. So I copied yours. Thanks. biggrin.gif

nice overclock, but you need to run OCCT for a min 20min in full screen with shader complaxity 8 and enable error check. if you get no errors then you got a stable over clock.

Nice oc, my max stable OC was 950/1900 (core/shader) and 2100 mem. but my 24/7 clock is 900/1800/2100

mine are very similar just the memory it's @2000MHz and run everything stable all day playing games and watching movies, also making some benchmarks and stress test like kombustor (of course not at the same time, i won't push my luck to much lol)

voltage 1.087v
core 900MHz
shader 1800MHz
memory 2000MHz

16llgu9.jpg

then i raise 930/1860/2200 and there was problems, with this setting the heaven benchmark run fine but in crysis and aliens vs predator (DX11) the graphics are not good, in both games the buildings and vegetation seems their images are repeated in the sky it's like the kaleidoscope effect, I don't know exactly how to explain, and in crysis the map only see the bottom half, the other half is blurry, and objects marked on the minimap are also fuzzy.
The OS never crash but is not fun to playlike this, and every time the game just frozen and had to close and restart again

I think that's happen because of the memory @2200MHz, i will try again with the memory at stock speed

I forgot to tell my card is the 768Mb version but i think is similar in the core and shaders frecuency

Nice overclocks!
Been pushing my card a little further and have managed to achieve this...
gtx460cc.jpg
OCCT 20 minutes stable at shader complexity 8.
Furmark stable for 10 minutes.
Will test my card for longer though.
So far 100% stable though.
Only thing worring me now is the temps, my 460 hit 80c in occt :/

Anywayz, it runz beast tho, lol.

Peace everyone smile.gif

Mine only goes to 850:(

Need to up the voltage i think. What's the max voltage i can push through this thing??? 1.050???

Might be getting 570 at the end of the month so i'd like to hit this cards peak.
