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!!

[Backbone]

Try some bencs

[largon]

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

Yes.. memory caused the artifacts.

Awesome

w00t!!

1/1 lol

nice one sampsa

[wfarid]

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

Grats, on the huge milestone.

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 was thinking to ask whats up with the ATI EXPRESS ?
and why you us nf4 board, that mean that x200 is not great for oc ?

and great work sampsa

I have a Sapphire's PURE CrossFire motherboard here with RS480 chipset but unfortunately I haven't studied it very carefully yet. DFI's nF4 board was a safe choice.

I'll post some 3DMark05 results on Thursday. Lets see if I can hit 12500 with a single card.

if some one can - its you !

Good luck then with it sampsa.. Hope you can

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

[funkflix]

Nice scores ( ), but

Not really, or?

[Sampsa]

Not really, or?

Yes, I was testing 3DMark05 at +900 MHz speeds but there is a strange behaviour which crashes 3DMark05 in the end of GT3 when VGPU is beyond certain value.

[funkflix]

Ah ok, hope u can fix that. Maybe hardmods for voltage is better, i think we will see them anyway in the near future, maybe cap-mods too, or something.

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.

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
