*** Nvidia GTX 460 Overclocking Thread ***

[Unrealer]

Am I missing something how is it in 3dMark11 I have the 768mb version but it seems like that shouldn't be reason enough for half the score? My graphics score is 3655

Like I beat this guy 734 MHz 1024mb Graphics Score 3261

But I get stomped by this guy with the same core clock as me 801?? Graphics Score 6291
http://3dmark.com/3dm11/1816392

Please explain how the 2nd guy doubled me and this other dude

6291points on Entry Preset, not Performance.

Oh so thats why some people are E's and other are P's... What's entry preset?
Well it seems like my scores are normal then... Someone on here was saying my scores were low before.

Entry preset
This preset is designed for benchmarking with a low level of load on the graphics card. The benchmark runs in 1024 x 600 resolution making it suitable for most DirectX 11 capable systems including notebooks and netbooks.

Performance preset
This preset is designed for benchmarking with a moderate load on the graphics card. The benchmark runs in 1280 x 720 (720p) making it suitable for most DirectX 11 capable gaming

eXtreme preset
This preset is designed for benchmarking with a very heavy load on the graphics card. The benchmark runs in 1920 x 1080 (1080p). Although this setting may well bring many PCs to their knees today it represents the likely loads used by high end games in years to come. This preset is particularly well suited to high-end gaming PCs.

Awesome! Thanks unrealer, that was really helpful. How hot does your card run at idle? Did you need to do a voltage mod to go to 930? I'm leary about going to 900 after Kets first 460 blew itself up.

By the way install the 285.27's I bet you'll get a big jump. I got a 400pt increase.

35-40º idle, and i get 930 with vcore bump, of course...

And the score is old ("12/7/10 10:32:31 PM")...

Regardless try the new betas then run the test, I'm real curious what you'll hit now

Hey, in the end I managed to flash with Ket's modified bios that unlocks up to 1.2volts and all went flawlessly. I also installed heatsinks on the voltage regulators. Max I can get to stable is 880/4100 in SLI with 1.1volts...even if I give it more juice, it will crash and give a black screen when it heats up too much (cards go over 90C if I give more than 1.1volts).

I suppose that's the limit?Any tweaks you can suggest?

90C is really high, you sure the HSF is mounted properly? What about fanspeed?

[utilizatori]

my GTX 460 AMP needs 1.2 for 950 mhz

[Ket]

Ouch... unless those VRMs are kept really cool I wouldn't pump that much voltage through 24/7. Around 1.1v max for 24/7 and even then you still need to make sure the VRMs have a good heatsink on with good TIM at least.

[dafour]

Is that msi 1gb bios on the page with all the modified bios'ses good for my Cyclone 460 1GB?

@ket Looks like we had the same trouble,i had a cyclone before that did 930 core but vrm's blew up,now this one wont go over 875 on 1.087

[BababooeyHTJ]

In case any one cares Frozen cpu has some thermalright brackets on order for GTX460/560 on order. They should be coming in soon.

Update !!

[mudkip]

So I installed the Arctic Accelero XTREME Plus on my GTX 460.

Absolute beast of a cooler. One problem, somehow the fans won't spin when connected directly on the 3pin header of my 460.

I have to manually run it at 7v with an adapter. Which leads to another problem: VRM overheating when using Furmark.

GPU only reaches 56 degrees max, but after 3-4minutes the VRM temps get too high and I get a black screen. I believe if I could run the fans at 100% then the VRM overheating would be gone.

It runs 3Dmark and games perfectly fine though. I tested 900MHZ @ 1.0875v today and it ran 3Dmark 11/Games without any problems.

There is VRM cooling on my Gigabyte GTX 460, but there is a thick thermal pad under the vrm heatsink. Would it be better to replace that pad with Arctic Silver 5?
