AtiTool OC'ing reaching huge clocks

Hi,

Looks like im back here for some help again. :p I got AtiTool last night and i was experimenting trying to reach different memory clocks, i have hit a max core of 740 (1.475volts) but have not hit my max mem clocks yet (so far 810). Im having trouble loading a profile with the new voltages and memory clocks from yesterday. My core speed has been left at 625 so i can find my max mem, which, so far, has no artifacts when left with RTHDRIBL and the AtiTool left running for an hour. Any ideas? Do i have to run my new volts 24/7 so that AtiTool just changes the clocks when i load profiles over? Or am i doing something else wrong :confused:

atitool lies. play a game at the clocks it sets and you might notice a load of white crap all over your screen, followed by a nice crash. If you dont then thats good
 
Be very carefull with ATI tool, i thought i had a fantastic o/c on my old 9800 pro till it fried :eek:
 
Hi,

Hmm i chose to use AtiTool because everyone else seems to use it and get great results. I have just tried playing css with my new mem clocks (625/810) for about half an hour, didnt notice any kind of distortion or artifacts. My stress test fps went up by 10 fps.

Its all going great except that i cant load the same clocks and voltages from a profile, i have to do it all manually every time :confused:
 
Hi again :p sorry to keep spamming my own thread lol, but i have just found out that the switch between profiles is fine if the voltages are kept the same but the clocks are changed :D

Can someone please verify that these voltages are ok for 24/7:
Core: 1.475
MVDDC: 2.050
MVDDQ: 2.050
VVDCI: 1.563

Temps on core never exceed 45c, temps for voltage regulators are always less than 95 even after hard gaming.

So basically you cant change voltages on AtiTool within swapping/loading profiles? You have to keep them the same? I would rather run lower voltages in 2d mode you see so thats why im asking...
 
People always seem to underestimate the temperature a component can take. 90 degrees is a bit high, but if you've noticed no issues, it doesn't matter.

Its also known that high Vreg temps = lower clocks.

My Vreg temps are 10C less than my full load temps...
 
buy this for the voltage regs:

should drop temps by a bucket load.
 
Got your Antec 900 then Cyber :)

What do you think to it?

Still very pleased with noise and temps on mine!

(sorry for off topic ppl)
 
yea i love the antec 900 its brilliant. only thing now is the dust collection is quite high. have to clean it out regularly. its done wonders for my vrm temps though, never exceed 65c when under load in this case.

but from reading oround the best mod for me to do is to take off the stock vrm heatsink, sand down the bottom of the pushpin holes then use thermal paste to put the heatsink back on. apparently it provides a massive drop in temps. other forums say that on average its a 5c drop in temps or more.

will do this later this week then be done with the card modding and get on with some games.
 
Cyber-Mav, thats a huge ass heatsink!

For now i have screwed 92mm fan ontop of my x-fi, looks good and has cooled my ram from 50 under load to 42. VRMs are now from 90 to 72. Should be ok, but im still gonna put the heatsink back on with thermal paste

Be interested in the temps after that mate? Pleased with my 900 too and the HR-03 keeps my card nice and cool, haven't over clocked it loads really 635/765.

I need to check my dust situation this weekend actually, get my can of air out on it :)
