ATI X1800XT OC @691/1628 All Air

im sorry for the mixup ahmad. My bad.

Thanks for the links too, didn't hear about this till now. All I see are the X1800XT's being benched with this fix though I'm sure X1800XL users should see a boost as well I hope.

Think I can sell both my BFG 6800GT OCs and get one of these?

In 1280x1204 the X1800XT gets :slapass:ed by a 6800Ultra.
In 1600x1200 4xAA/16xAF the X1800XT gets :banana:ed by a X850XT-PE.


Moreover, nobody can say, this game is NV-optimized since even the X850XT-PE can beat the X1800XT. This card is just a sucky underperformer. High 05 scores but no real world performance at all.

ATI's new driver will fix it's OGL performance, if it beats the 7800GTX then bye2 NV :D

x1800XLs will see a very worthy improvement in performance as well.

wicked. All I am worried about is these so called defective cores with the softground issue. I want to know that getting an XL will hit XT speeds with a new cooler and a voltage jump.

Its already been covered. Someone asked ATI and they said no card they shipped out had any softground issues. No need to worry. Besides the softground issue limited clocks to 490MHz. X1800XLs come default at 500MHz core.

the softground issue also had chips randomly failing...

Well as long as there is no possibility of me getting them on my card I don't care anymore.

here buddy, its quake 4, but same thing basically.

Yep, it's good to see ATi tweaking the x1k series for OGL and/or reworking the way they handle OGL period. That's long overdue.

And yes, I think the soft-ground issue has beaten to death. The XL's most likely shipping now were the ones with the softground issue, ie the first batch of R520's, but they have been fixed with a new layer of metal or summin', which alleviated the problem. I think that with the independant testing we've seen around here (Sampsa and Fugger) it's been shown the XL cores clock just as well when given the same voltage and cooling as an XT...and without, and this is for my homies at R3D,
RENDER ERROR
So have no fears buying an XL. They look pretty impressive to me for less than $400...If you are hip with giving it more voltage and more adaquete cooling. Sampsa's 705/705 with his XL with XT cooling and vgpu@xt and mem@stock voltage and Fugger's presumbabley topped out 776/1800 on water...I'm impressed. Pretty sure a GTX ain't touching that, especially not that easily.

ATI HAS to come out with a final driver release for x1k...

I was beyond XT voltages with my XL card and I pushed my memory very hard.

I did have a problem with phase change at first. the machine fired up but the video card was left off. The block was not grounded to the ring.

The waterblock ring is completed ground as well as the LN2 mount. I froze over too fast twice on LN2 and switched to the water to make sure card was ok after a couple pretty hard scrambles and tons of moisture on card (rained a bit that week).

I will try phase change again with a ground to the block.

The card scales so nicely as you go up in memory speed even with a much slower core. IMO they should have set the XL at 1200Mhz memory to better position with the GTX.

Checking out Q4 now, plays nice so far. I am in the nexus core.

I'm getting around 740/1680 clocks (artifact free for 3DMark05) with the default cooler (GPU +0.15V above default, fan running at full speed).

Already posted on the other thread but just in case someone missed em =)

my results so far w/ the Zalman CNPS-7000CU on GPU:
3DMark05 => 10707 (3GHz, 759/1738)

i was thinking about buying a silencer type HSF for my XL, should i instead get that zalman one, seeing how according to you its better even than the massive XT stock cooler? my XL will do 628 core at 1.225v and 1550 mem at stock.

oh and where are the ramsinks, did you leave them off and it still did 1738?

bring in grayskull to see why they didn't, if 1200 memory postions it against 7800gtx, why didn't they !!! :confused: :confused:

Now that we know what killer oc the XL gets, I hope this 691/1628 isnt the max for the XT on the stock cooler. If so, that would make the XT weak, especially on the memory side.

i think fugger probably meant the 7800gt, as in reviews it doesn't often beat it, with higher mem clocks which it can easily, very very easily do then it might always beat the gt, or at least it will take a smaller hit with aa/af and probo beat it in most higher resolutions.

also you do realise dude has the cpu zalman on his gpu not the ickle gpu zalman.
also the memory doesn't really get hot, i stuck on memsinks, don't think they are really doing anything mind but thought why not. though from the last pic there, it looks like he may have bent around or cut some of the fins from that sink to make it fit. not to sure.

How have you mounted the sink, default bracket?
