Calling all gtx 460/hawk users!!

post #1 of 14
Thread Starter 
hi guys
i have a gtx 460 hawk talon attack.
default clock 811mhz 1622 shaders and 1950 memory

now i tried ocing and the max i could reach was 910 that too barely stable enough to do all benches and stress tests.
reaching 920 was simply not possible even with vcore set to +100mv and pll set to +10mv.

so i currently am running at these settings
900 core 2000 memory with +100 mv core voltage max temp 64c according to afterburner.

zMARP.jpg

so now i have got 5 questions for you guys:

1) is it safe enough to run at 900 core and 2000 memory with +100mv on the core 24/7 ?

2) is it normal for hawks to not achieve 920 stably with +100mv ?

3) how to oc my card further up ? and also tell some general procedure and stressing tools.

4) whats the max safe voltage limit for hawks ?

5) does increasing pll voltage have any affect at all on oc or stability of the gpu ?

thank you for your time smile.gif

If it is stable you should have no problems I have frequently ran mine between 850-950core and 2100 memory clock and have no problems yet, not all cards are the same though.

PLL doesn't affect GPU stability.

Personally the MAX. I have gone that was safe and stable was @ 1.1v.

To test stability use some type of benchmarking software and run it on loop, be aware of crashing or distortion in images.

ok...so how much voltage does your card require to be stable at 900 core...mine takes almost 1.09-1.1volt
i was wishing i could at least go upto 950 core stable at same volts,but its not even stable at 920 core
and it would be more helpfull if u replied to my questions in order smile.gif

1. Yes

2. Every GPU is different, you might just need more Vcore, through Graphic Card BIOS ReFlash.

3. Same as 2...you gotta get lucky on the GPU. Now you will need to do a BIOS Flash on your 460 Only, that should get you up to 1.1-1.3V on your GPU, then OC from there, and i would use Uniengine, ATITool OR OCCT smile.gif

4. Honestly the highest i have ever seen after BIOS Flash was 1.5V, but that was Nitrogen cooled so i would say 1.2V is as high as i would go..Watch your temps though...under 75C is good smile.gif

5. No, just ups the volts used to run the x16 Bus, if anything it helps when you OC the Core and Memory.

Good Luck! smile.gif

okay my final question here before wrapping up this thread...

how does i know my gpu is getting too much or too little voltage...

for instance i started getting red,blue,green colored dots,sprited in 3d mark vantage test with a particular vcore and it started reducing as increased the vcore....

similarly how to know if my gpu is gettin too much voltage is there any thing to look out for...

my max temps have been 68 with 890-900 core @ 1.1volts.....
post #9 of 14
There's no way to be absolutely certain, but for piece of mind i would just max out voltages in afterburner and see what you can get and be happy with that, 930 odd isn't going to make much difference over 900. With my voltages all maxed i run 900,2200 on the memory. It crashed once so then i
Put the memory and pll sliders all the way and it's been rock solid since. If you really wana see what you can get, google gtx hawk on overclock.uk and a guy tells you have to edit the afterburner ini. or config file to bypass the msi voltage chip and start using the onboard nvidia one. You just add a line of code to the file. You do this after maxing the slider to +100mv. Then after putting the code in, it goes back to the way the voltage looks with most cards and let's you stack 1.087 with +100mv = 1.187v.

I was benchmarknstable at 960mhz. Just didn't fancy frying my card so i don't run that speed.

Well the dots mean not enough so up the Vcore and to much?..when it fries. So be careful smile.gif i would stay below 1.3 though, unless you got Amazing cooling for your GPU, VRAM and FETS smile.gif

and your Temps are gold, just stay below 75C, the lower the better though, so throw a fan on it, get a Aftermarket cooler or go Water, up to you smile.gif
