let me say what it's the problem
I have bought a gigabyte gtx460 OC 1gb, ok it works without problem but ... :(
My gpu can go @ 850mhz whit 1.037v very stable (OCCT) without problem, under stress test i get 74° of temp
The problem is that over 850mhz, my card will not run stable
2-3 months ago, i have test it @ 875mhz 1.05v, but after 5 min. i saw 1 error.
today i can't run stable it with 1.075v, i get error in 1 or 2 min.
What is the temp critical for this card?
Fan @ 100% always under test
I try to change thermal compound with Artic Cooling MX3 ( -2° vs stock ) but...
Sounds like the VRMs might be getting too hot.
i also thought that, how can i do? in theory, vrm are already cooled
Take the cooler apart entirely and replace the stock TIM used on the VRMs with something good.
Pretty stoked!Quote:

Is there a way I can unlock more voltage over the 1.087v limit?
yes just use NiBiToR to open your bios and set max (up to 1.21v)then save modded bios and flash to your card
how to guide

its rather simple
See sig for "golden" GTX460. With a lower mem clock it'll probably do 950 on the core.
930/2200MHz mV 1.075V.

Nice clock, my first Cyclone did around those clocks before it comitted suicide (VRMs blew up)
Really? You think I should reduce these clocks? I'm still testing, I'll try lowering the voltage, but I probably should not get. Let's see.Quote:

Climbing a little more ... limit to 1.087V.
950/2240MHz:
Temp máx 55ºC (Kombustor @ 60% fan speed) - Temp ambient 17ºC.
http://www.abload.de/img/teste11-950-2240mhzpcnr.png
What is the maximum voltage that I can use in 24/7 without any problems? It would be 1.087V?
Kombustor is a poor test for stability. Run Unigine Heaven instead it will put the GPU and memory under extreme load.
Kombustor seems like the new ATI-tool to me.

It really shouldn't be. Just run nvidia inspector with kombustor, then run Unigine Heaven. Heaven stresses the memory and GPU far better. AFAIK, kombustor stresses GPU about 60%, practically zero stress on memory. Heaven stresses the GPU around 96% minimum, and virtually all of the memory is in use.Quote:

Yep deffinately. The 460 has a lot of muscle for such a little card. My 460 at its clocks actually outdoes a stock GTX470, and possibly a 470 with a mild OC as well. The key to remember is to consider the resolution you game at, quality of textures (ie; size, detail, etc) and how much bandwidth you realistically need to handle those tasks with minimal to no bottlenecking going on within the architecture of the card itself. Once you figure that out, you can pile everything else into the GPU for raw speed.
Taking my clocks as a example;
GPU: 902MHz
Memory: 4310MHz
Now, I game at 1680*1050, like to have 2xAA and 8xAF (4xAA doesn't give a very noticable difference IMO and there is pretty much no visual difference between 8xAF and 16xAF) and the most graphically demanding game I probably have is Crysis Warhead which I play at "Enthusiast" settings. Based on this, I can actually reduce my memory OC to 4200MHz and basically have zero FPS hit as a result which would in turn;
- Reduce heat from the memory
- Reduce strain on the IMC
- Possibly increase wiggle room for max stable GPU clock because of the reduced heat and less strain on the IMC
With all this done instead of 902 / 4310 I could end up with 930-950 / 4200 without increasing GPU voltage above its current 1.1v. Sure, I sacrifice some bandwidth but the FPS decrease from doing so won't really be noticable even at 1920 with 4xAA and 8xAF, if I had to guess, maybe 1.5-2FPS. In return though I gain 30-50MHz on the GPU which would give me around 3-5FPS more meaning even taking into account the lower memory speed, I still gain.
Thats rather a long explanation probably going into too much detail about how I consider the architecture of any component while OCing, but hopefully you understood the meaning :D
Hi all, I have 2 Palit Sonic Platinum GTX460s and I would like to mod the bios and be able to overvolt slightly higher. I have never done this and am completely clueless on how to. Would any kind soul give me some "real time" help to flash them? :) I got some heatsinks that I will install on the voltage regulators as well!
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?
hi guys
I have such a request, I'm looking for the video card bios Asus GTX460 1GB DirectCU recently updated the versions 70.04.1B.00.02, but this causes artifacts all the time when the only pc turns on, the original had just such a 70.04.2e.00.04 and looking into my Asus
If any of the members has one, I would ask the toss on a private message
70.04.2e.00.04 bios version
gpu: http://www.asus.com/Graphics_Cards/N...rectCU2DI1GD5/
thanks in advance
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
http://3dmark.com/3dm11/1822097
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.Quote:

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...Quote:

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

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