Well finally Been following this thread for a while and was trying to post all day but had to wait for account activation. Anyways here is what I wanted to post.

Well im new over here but since theres been so much talk on these forums about the X1800XL I had to sign up and give some results that I had. I have a sapphire oem card, bought from newegg, and using the crappy overclocking tool. I really can't wait til ATITool gets released.

First heres some pictures.


Thats right fugger exact same core as you.

All air, got the FS-V7 cooler. Whats not in the picture is I added a 120mm fan thats at an angle blowing up at the card from below. Its wedged between the power and the sound card which I moved down a slot. And removed the 3 back plates on the back to let it exhaust through there also.

Heres the system
Motherboard -------- DFI LanParty Ultra-D (704-2BTA Bios)
CPU ----------------- X2 3800+ @ 2,507.5Mhz w/ 1.525V Bios / 1.488V Windows
Memory ------------- Crucial Ballistix PC4000 (2x1Gig) @ 295FSB w/ 3-3-3-8 timings @ 2.8V
Cooling ------------- XP-120 w/ 120mm ThermalTake 27C Idle & 39C Load
Harddrives --------- 2x 250Gig Hatachi’s (Not Raided)
Graphics Card ------ Sapphire X1800XL 641.25/801 (1.25/1.95V) using FS-V7 Cooler 3D Marks (05) 8,933 / (03) 16,678
Case ---------------- Antec Super LanBoy
PowerSupply ------- OCZ PowerStream 520W
Monitor ------------- Dell 2405FPW LCD 24" Of Pure Enjoyment

Running XP w/ SP2 and I'm using 5.11 Beta's the latest one I could find 8.183. And I can not get CCC installed for some reason, even the 5.10a's, or even the CD version, really strange.

Well onward to test results, I have more on paper at home but this is what I've done so far. There has to be something screwy with the bios on this or even the early beta drivers because there is some issues.

500/500 (05) 7214 (03) 13702 (01) 26044
600/675 1.2V/1.9V (05) 8336
627.75/747 1.25V/1.9V (05) 8603 (03) 16079
641.25/801 1.25/1.95V (05) 8933 (03) 16678

Sorry was mainly running 05 test because if I had issues in that, it showed much quicker then the other tests, and it was much easier to judge frame rates to what I should be gettting (the last OC I just ran out of time it as late otherwise I would of done a 01 test too)

Now I can't get higher on the Core, either with more voltage or just clocking it up. Now if i bump the core up to say 650, it crashes in 05 nature test, but if I up the core it crashes most of the way through the test on that one. Memory its the same thing im in a sweet spot, 1.9V artifacts, 2.0V it artifacts, upping the clock artifacts. There has to be some issue because I'm sure this has alot more life in it.

Overall if core is unstable it locks the benches up hard. If its a memory issue I get a semi checkerboard type pattern, just extremly small from what I've seen with past cards. To high voltage its a colored pattern, to low its a black pattern which quickly turns into highly destored textures.

Now I don't think its really heat related issue but more of a driver/bios problem then anything. Since I don't have CCC (kept getting some wierd network error with it) I can't tell the temps on the core, but just seeing what others where getting at least gives me a ball park figure. My heatsink was reading 44C's at its high point with a thermal sensor, in tests mainly the hottest it got was the 05 nature test. Games it got up to 46C max so thats why I don't think its really a heat related issue.

Oh one other to add to the pile this was a benchmark in fear.

Fear @ 1440x900. During the testing, I got these scores, everything at max, and 4x AF, no AA. 39min, 62 Avg, 116 Max, 2% between 25 and 40, and 98% above 40.

Fear @ 1920x1200. During the testing, I got these scores, everything at max, and 4x AF, no AA. 22min, 37 Avg, 71 Max, 3% below 25FPS, 62% between 25 and 40, and 35% above 40.

Now the high res one, well that ran better then my old X800Pro (w/ 16pipes) @ 1280x720 Totally amazed with the preformance of the card.
