First time overclocking-4830

[sprayall]

Can you guys please help me out with this? I’m new to overclocking. I ran ATI Autotune and it came up with 640/990 for core and mem clocks, respectively.
I tried using ATITool for OC'n a 4830, but clock speeds don't show above sliders. I run "Find Max Core" for over an hour and no clock speeds are ever shown. Am I doing something wrong or is it just not compatible with my card?
So now I’m using Rivatuner to change clocks (starting with the 640/990 settings), ATITool to check for artifacts, and GPU-Z to monitor temps. Upping the core clock by 5MHz and scanning for artifacts each time. Am I going about this correctly?
How long should I let the scan for artifacts run-10 minutes? And shouldn’t the cube be revolving during the artifact scan?
Also, it seems that most feel that 85C is the highest desired temp for a GPU. Does this seem about right? And what about GPU Temp(MEMIO)? It's already running 72C at 706/990 MHz. There's a screenshot attached below.
Any advice at all would be very helpful. Thanks.

Ok, first off, you won't need all those things to OC, just OC through CCC for starters. It will be much easier. The cube in ATITool for me never really did anything, just didn't seem to put enough stress on the gfx card. Here's a free app that will put enough stress on the gfx card to put out artifacts.

Temps are meh, in my expirence you see artifacts you tone it down, that could mean temps too high or you've hit your cap without bumping up the voltage. But if you do want to monitor temps 85C is a good start, but really 65C and lower is nice to see. Also you can tinker with the fan settings with CCC to get better cooling. Also todays products are built a quiet bit better, don't be afraid of burning it out without voltage bumps and bad cooling (combined). IMO just set the GPU to 700 and play some games or run furmark and go from there. Most 4830's can cut 700mhz on the GPU, after that tinker with your ram, not sure on the clocks with that, but 900mhz wouldnt seem too unreasonable.

I agree with Kurgan. Use the CCC to overclock as ATI tool can be a tad twitchy these days. That or use AMD Overclocking tool.

I thought AMD Overdrive was for motherboard chipsets. It’s not made to work with my motherboard. I’m not using CCC because it tops out at 650/1000 and I have no fan control anyways (only 2 leads going to fan). I’m at 719/1000 right now and planning on pushing it farther. It seems like my cooling setup is working (at least a 10C drop).
The artifact scan put about 90+% load on GPU according to GPU-Z. I figured that was a good load. Main thing I’m running is FSX and SolidWorks, and these only put about 50-60% load on GPU, so my temps run way low (41C and 44C, runs 65C and 74C during artifact scan at these clock settings-see screenshot). I didn’t see anything weird on the screen so it’s OK to push it even more, right? Or do I need to use OpenGL Fur Benchmark and stop increasing clocks when that shows instability, eventhough my card will never be loaded that high?

Not AMD Overdrive. AMD GPU Clock tool. It's in the downloads section here at TPU. Right, you will see screen corruption. Furmark will generate the most heat and probably the most load. Also, test with 3dmark06 and that will tell you if it's stable.

I just used ATI overdrive but i wouldnt use auto tune anymore it pushed my core to 690 and memory to 1020 and i got aftifacts in css menu and crash i will manually overclock it using ati overdrive and test each settings ingame or another stress testing application for gpu.

 

[1Kurgan1]

Most likely the memory was the issue there, 1020 is quiet high.

So, at the 719/1000 settings FSX, SolidWorks, run fine. No screen corruption and temps were good. But Furmark did freeze the screen-had to hardboot. Here's my question. Can I run at these settings, and maybe even a little higher, or will this somehow damage the card? Or should I not because Furmark is showing it unstable at these settings? I may, in the future, use some application that loads the GPU alot heavier, right. Is this the logic behind not pushing it further? Again, the temps are low, 42C and 45C(MEMIO).

Yep it was the memory i lowered 990 and it ran fine

If i were you i would get it stable enough to run furmark i wouldnt push it further

recently ati tool hasn't worked for me at all..
I use riva tuner.
lets you run your gpu fan at 100% and lets you overclock.
then I just stress test in extended game play.. it's the only way I've ever been sure.

running 3-d mark (future mark) is a good indicator in general of stability.. but it's no sure fire test.
the only sure fire test is extended game play or extended tests that run for hours.
could loop future mark tests for hours to accomplish this.
I'd rather play for those hours..lol..

I also run it at max settings.. just to put the maximum stress on my gpu..
but depending on your gpu I would run it at a level where your pushing like 20 fps or less.
so you know your really stressing it.
set the anti aliasing and antistropic filtering higher and higher until you reach that point.

Then what conclusions should I draw from Furmark freezing the screen at the 719/991 setting but the card runs cool, with no screen corruption, during and after many hours of game play (FSX)?
