Help for an X1600XT OC!

[Foehammer2003]

Ok so i have a not so great GPU, but would still like to get the most out of, Currently using ATITool i can get from stock 590/405, to 655/405, yes no OC on the mem, there is a good reason for this!

Whenever i get past 410Mhz on the mem, system just locks up and i have to cold boot, cooling isnt a problem as far as im aware, and i can take the core speed up to 679 before it is unstable, but leave it lower just to be sure.

Anyway the mem speed is going to affect the fps a fair bit yes? So any ideas in how to get this card to play ball? Overall i would like to clock it to as much as i can with it being 100% stable, does anyone know what speeds are possible with this card?

What version of ATI Tool are you using?

There are other options aswell, I used an X1800XT for the below testing, but most of it still applies:

I've tried most options available to clock my X1800XT 512MB:

1. ATI Tool 0.25 Beta 14
2. RivaTuner
3. Overclocker X1K
4. Catalyst control centre
5. Other (BIOS flash)

ATI Tool:

-Used the latest Beta 14 version
-Clocks ok, artifact detector seems to work for me, but errors very early.
-Sometimes cause system hang when switching from 2D to 3D clocks and back.
-Causes system hang on switch to 3D clocks when starting BF2 with Cat 6.5s, works fine with 6.3s
-ALLOWS VOLTAGE CONTROL

RivaTuner

-Great hardware monitor
-Clocks my card fine when I turn off enable overdive in the MORE section on the overclocking tab
-Seems to give me errors at lower clocks, may have to do with memory timings
-No voltage options
-2D/3D seperation can be achieved by using profiles for individual applications. There is also an option for Overdrive clocking, but this simply caused my clocks not to change in 3D mode when I tried it with the Omega 6.3s. Will try with the 6.5s and report back.

Overclocker X1K

-Tried briefly, simply alters clock speeds.
-IIRC it allows core voltage adjustment, but memory didn't work on mine.

Catalyst Control Centre

-Trying it now with 6.5s
-Only allows upto 690 Core 800 Memory
-Smooth 2D/3D switch, hasn't caused me any lock ups yet
-No voltage options

Others:

BIOS flash -> tried flashing my card to X1800XT PE, only works with 512mb cards, but is very simple to do and is done via windows.

Was getting slight memory errors so flashed back.
Boosts clocks to 700/800 iirc, and ups core voltage slightly, should be fine on air as the real Sapphire X1800XT PEs use the same cooler and are identical apart from clocks.

Tips:

It seems memory voltage can often to be REDUCED to get better clocks on the memory, I found that reducing MVDDC from its 2.097 stock to as little as 1.825V continued to give me gains on memory clocks. I'm not the only person to have found this though the sweet spot is different for others, and the memory on my card sucks, it can't do 800Mhz without artifacts so far.

0.25 beta 14, this is the latest i think from techpowerup, well it was the latest stable version about a month ago. Has it been updated?

So rivatuner will work on ATI? lol, i thought it was only good for NVidea! Cool!

CCC wont let me change any clock speeds for some reason, i have v6.5 but no overdrive or OC options!?! Dont know why, my card may not be supported though.

Give rivatuner a shot, its excellent

Will do! cheers mate!

nope! RivaTuner still has the same limits as ATITool, perhaps upping volts would help but nothing seems to support this card lol, oh well guess i will have to stick with the OC i have, unless anyone else has any ideas?
