Radeon X1800XT and GeForce 7800GTX 512MB upping the ante...

Just saw this article, and it shows how "extreme overclockers" manage to force the most out of this cards... They took some professionals: Marcus Hultin aka Kinc (world record holder in all three 3DMarks), and Robert "Crotale" Kihlberg, who is a serious boy as well (Celeron 2.53 @ 5.2GHz and P4 660 @ 6GHz e.g.)

Those two bundled their forces and started taking on ATI's and nVidia's top models... The maximum clocks of the Radeon X1800XT were 840MHz core and 1.84GHz memory, whereas their sample of the 7800GTX 512 experienced a "cold bug", which would not allow it to go below -20°C... Maximum clocks on this one were 729MHz and 1.908GHz... This was achieved with Extreme Cooling...

On air, the 7800 could get as high as 702MHz on the core, and a higher 2.02GHz on the memory... Together with a FX-57 @ 3.15GHz, that made for over 12k on 3DMark05... The X1800 was not as fast with just 11k... (clocks were 740MHz and around 900MHz)

Still a very impressive result by those two, you can read more about it here...

Heh, guess the 3 most recent ones, who uses 3D Mark 99 or 2k any more???

i don't think 99 will install on win xp

iirc i ran the one with the choppers on XP way back (probably 2k).
 
For what it is worth, all versions of 3dmark will install and run on Windows XP.

All but 3DMark99 will perform properluy when run too (including xlr8r - same vintage as 2000).

The reason 3DMark99 won't work is that it's hard coded to check for DirectX 6.1 and refuses to run if it doesn't find it. Could probably be fixed with a hex editor...

Slightly off topic, microsoft should really include options on the compatibility page of shortcuts to specify the DirectX version reported to the app and the amount of system ram reported to the app.

Um, a while back someone got a 1GHz core clock on an X1800XT; these aren't THAT impressive IMO 😉

Agreed.

Impressive indeed, but abit hallow since the card could not render at all and there were artifacts in 2d.

1ghz is amazing but it wasnt stable. (artifects etc)

It was stable, the computer didnt turn off. You think these systems had no artifacts either? If you OC something to the point of phase-change, you are garenteed artifacts, and if you have the balls to be doing that then you know whats going to happen.

Also, remember the 1ghz X1800XT? It was running on that special bios/OC platform that changed the voltages of the card.

You know why it wasnt benched?

Actually if there is artifects it means its not stable. Whether or not the Computer was turned off or on. This is the point of extreme OCing. How far you can OC the GPU/CPu etc to the point where its extremely fast AND stable enough to be benched without artifects, texture corruption, etc. This is the art of extreme OCing. The risks taken, the process taken etc are all the satisfaction behind this art.

ALL cards that are extreme OCed is either running under a different bios, or volt modded in someway or another.
