Radeon X1800 XT (GPU: 1 GHz / Memory: 1 GHz)

[Sampsa]

I think this one deserves own thread.

Yesterday W1zzard was able to provide me a beta-version of ATITool which included options to raise the GPU speed for R520. Well.. it worked and didn't crash at 860 MHz limit where I was stuck with ATI's internal Winclk utility.



Radeon X1800 XT was cooled down to -80 Celsius and I applied some extra voltage to GPU and memory.

The result:



Radeon X1800 XT running GPU @ 1005,75 MHz and Samsung 1,26 ns GDDR3 memory @ 1003,50 MHz (2007 MHz DDR) in 2D-mode. No 3DMark05 yet.. I'll try that next.

I think this is the first time in world when graphics card breaks the 1 GHz barrier! On CPU side we saw this 6 years ago when Intel and AMD were really pushing Athlon and Pentium III to 1 GHz.

Thanks to W1zzard for providing a beta-version of ATITools and my co-editor Suvanto for helping me during the tests.

Way to go Sampsa!!!

Diggin' the screen artifacts in 2D....Xtreme!

Congrats on the landmark clocks!!

Try some bencs

[babyelf]

w00t!!

1/1 lol

nice one sampsa

The artifacts were memory based, weren't they? No problems with GPU @ 1GHz?

Yes.. memory caused the artifacts.

Awesome

holy cow, congrats! can't wait to see more

Grats, on the huge milestone.

on a NF4

Whats up with the "INTEL" hard drive?

was wondering that too..

Great overclock..

Hehe we have labeled few of our hard drives just to know for what platform OS is installed. This disk has couple of Win XP's installed in it and it used to be our Intel HD

Thats very cool Sampsa

And a very big props to W1zzard for making our life much more interesting with X1800

I kinda assumed that but I was poking fun.

What vcore was this done at?

[Sampsa]

What vcore was this done at?

I used 1,525 V (default 1,31 V).

Not sure if the GPU even needed that much to hit 1 GHz in 2D-mode but I was doing some 3DMark05 runs at +900 MHz speeds

Gold plated copper block I will feed LN2 through tomorrow morning.

Default core on mine is 1v and I can get to 1.5v I will soon find how close the XL and XT are.

I can do 1.5Ghz memory now, and I know 1.6Ghz + is still possible on this 1.4ns stuff.

me wants! ME WANTS!

awesome work dude

and FUGGER..... @ that block...

I think they are pretty much the same. So getting your GPU also beyond the 1 GHz shouldn't be a problem at all. Good luck

Holy Fugger, better get some insulation on that thing

bench bech bench cod2 fear...

@Troman,

Whats your glitch man? It's obvious what this is, a congrats would be in order if you had any class.

How did you get the mem so high without cooling? (Or did you rig up something else that's not pictured?)

I can run 3DMark05 with default memory voltage @ 940 MHz without any additional cooling (just dryice / LN2) on GPU. So getting a screenshot from Windows XP desktop @ 1000 GHz wasn't too hard

you can see the mem being cooled.....
