Overclocking the X1800XT - suggestions, results

[dnottis]

I can't push my memory past 780Mhz (X1800XT) from the CCC overdrive panel. Core does 680mhz no problems.

What are normal overclocks with stock cooler and without adding more voltage? Also, where can WinCLK 3.70 be downloaded from? I'd like a bit more on the memory - 780 Mhz seems to be low for the XT.

I tried the DriverHeaven tool the core wont break 675 with that tool. But I upped vmem from 1.8 to 1.9 vmem and now I'm running 3dmark 2005 stable with the memory at 800 Mhz.

So... the memory needs more volts to overclock? Is that what everyone is finding? Also, I can run the core up to 680 in the CCC without a problem, but this app caps me at 675 on the core?

Too bad we cannot just change the bios for speed and voltage and re-flash it. Maybe eventually we will be able to. I hate starting this overclocking app every boot and making changes.

The overclocking tool shows my memory volts at 1.8.
No wonder why I cannot overclock at all with stock voltage

I can hit about 830 with stock volts on the mem, The tool from driverheaven does report 1.8v, but from what i understand the chips are rated for 2.1v? Can someone confirm this? I havent taken my HSF off yet so i cant see the part number on the ram. Also I can hit 740 on the core with stock volts, after an hour of gameplay, VPU recover kicked in though.

Mine do 750/880 on stock volts. no matter if its 53 degrees aircooled, or 20 degrees watercooled. it does not overclock better with water at all:(

I also flsahed with another bios wich seems to have given me a smal boost:)

can only use the voltage with ati tool beat 9, but its still not giving me more oc room. hope somebody find a hardmod for this card soon:)

Dnottis# what is you nature score in 3d01 win xp stock clocks??

Can someone send me the ATI tool beta 9? I PMd wizard and got nothing.

Just nature - I'll have to check
getting about 32500 in 3dm2001se, I think my CPU is bottlenecking me in 3dm 2001 se

Just tried to run 05 again with 5.11's. I seem to be seeing what other have reported. If i set the core above 720, my scores decrease? It seems to be throttling. I might go back to 5.10a and check again...
