Here's my conservative OC attempt : Gigabyte GTX460 1gb OC (windforce dual-fan)

Stock core/shader/mem : 715/1430/3600mhz
VDDC stock idle/load : 0.875v/0.987v
Fan : Auto
Idle temperature (at core/shader/mem : 51/101/540mhz) : 36-40'c (non air-con, depending on weather)
Load temperature (gaming/benchmark @ 1680x1050): Up to 71'c
- Starcraft 2 : 63-64'c
- Heaven benchmark (DX11) : 70-71'c
- Battlefield bad company 2 : 71'c

3Dmark vantage at stock


Stress program : OCCT (GPU) 15 min (twice), 1680 x 1050, full screen, error check

Core/shader/mem : 715/1430/3600mhz (Stock)
VDDC : Stock
Load temperature : 80'c
Fan : Auto

Load temperature : 76'c
Fan : set to 100% above 70'c

Core/shader/mem : 715/1430/4006mhz
VDDC : Stock
Load temperature : 81'c
Fan : Auto (went up to 82% at 81'c)

OC stable at core/shader/mem : 785/1570/4006mhz
OC VDDC voltage idle/load : Stock
Load temperature : 83'c
Fan : Auto (went up to 88% at 83'c)




Could do normal gaming at core 830mhz but unigine benchmark will show minimal artifacts.....
At core 840mhz, gaming will cause the Nvidia driver to stop responding.....

At the moment, gonna run the card at stock. Not planning to OC 24/7.....

The high temp due to OCCT la. I think at stock speed also quite high temp when stressed with OCCT. Can't remember how high, tonight will see what is the GPU temperature at stock during OCCT.

Will post up GPU temp when using MSI kombustor too. Lower temps but can't remember how much.....

Yeah, no aircon. Core max OC is 785mhz (with stock memory). At 792mhz, got 2 errors on OCCT.

I have never removed a GC's heatsink before. I think should be quite simple but don't see the need for it as the temp for normal gaming is not so high like in OCCT.

Wow! That's a lot! Makes my hands really itchy!!!

Arrrggghhh!!! I was already happy with my GC as it is.....

Maybe I'll do it next week after I receive my Thermalright Venomous X + Silverstone F12 (x2) fans.... (Still worried about it's performance compared to my current Xigmatek S1283.... )

Removing the GC's cooler and reappying the TIM won't void warranty right?

Any tips? Just unscrew and pull?

Wah! Missing screws also can RMA ka?

Ok ok you've convinced me. Will reapply the TIM soon.... maybe even today!!!

I see. Thx for the tips! Have to go back to check whether there is any warranty sticker or not. I think not.

Opened up my rig. Took out graphic card. No warranty sticker on screws.... look at GPU/heatsink interface..... looks ok leh (thinking to myself).... think, think, think..... think, think, think..... decided to be a good boy and not touch the screws......

GC back in my rig. Gonna play some starcraft!!!

Cooler than mine.

Ler, in MSI afterburner, you can define your own fan speed la. Even better, you can set many points when you define your temperature/speed. Like the picture below (just an example):



I set 2 points, 50% until 50'c, then linearly increase to 100% at 70'c. In OCCT, I'm getting 4'c lower at 76'c instead of 80'c!!!!

Gigabyte twin fan also very silent, not like vacuum cleaner!

Unigine benchmark just press F9 to start right?

Here's mine:




Here's 3Dmark vantage. See my low CPU score (Q6600 quad at 3.12mhz)

Nice temp there. Try the OCCT GPU stress test. Interested to see the temp in OCCT.

Nice. Mine 76'c at full fan speed.

So, no errors in OCCT at 830mhz for 15 mins? If so, you have a good card! Mine can only go 785mhz......

Also probably the cooling on Gigabyte is not as good as MSI or ASUS. Imagine 81'c on OCCT!!

Nice. MSI more expensive ler..... how much you bought yours?

So cheap? What model? MSI Cyclone GTX460 1gb OC?

Damn! That's cheap! Prices for the GTX460 is coming down fast..... next time our GC no value......

How come your Feature test 1 is 1.3k???

Nice. Use a stress program to check for stability e.g. OCCT, furmark. Unless you want only gaming stability then no need to stress so much....

I don't see the point to OC above my stability point la..... let you all do the benchmarking.

My PCI-E v1.1 is also a bottleneck, not to mention my aging Q6600......

Anyway, just for fun, benchmark above stability point at 1680x1050!

MSI afterburner can tweak the voltage. I dare not touch it..... for now.....

Wah! Nice.

Are you planning to run at 1.075v VDDC?

How's the fan noise at 80%? (Ya, I know it is subjective, just wanna know whether it is noticeable or not)

Push higher!!!

Wow! I don't even dare touch my VDDC.... yet....

Nice! What's the software at the lower left corner, which shows the "Performance state"? Wanna install one too!

So you pushed your VDDC to 1.037v?
