ATI Tool has 2v stock, I will bring it back to 1.8v.

Memmory is rated by samsung @ 2V

1.8 is undervolting it.

thanks, I brought it back up

I swear I read a review that said that it was run at 1.8v, even tho it was rated for 2.

You did. That is correct!

ATITool does not work with the 3D Detection for me. Does anyone else have this problem at all?

And also ATITool reads voltage incorrect slighty... it is off by 0.025 according to RivaTuner.

Stock voltage on core is v1.300 not v1.375.

it will still show up as 600/700 stock (2d clocks) but when you move the sliders to oc it will switch to 3d, but still be showen as 2d

ATI Tool reads the voltage from the card. If it says 2V then the card is running at 2V by default.

So when I set clock speeds it isn't setting it right then...? It sets it when I enter 3D Interfaces correct?

The 2d clocks turn to 3d when entering 3d yes:)

Oh ok, Thanks. I will have to play with it alittle bit.

Do you guys still get the same overclocks using ATITool Vs. Overclocker?

Just wondering which to use when I get the card under its WaterBlock.

well..thats the strange thing here. i sudenly need a little xtra volt just to run 700/800, but my max OC is still the same 823/1000 hehe..:D

I mean ati tool beta 11 and 3d clocks. beta 10 i used 2d clocks:)

See in Beta 10 Clocks didn't work for me.

Wait, lemme get this straight... so ATI purposefully undervolts the RAM? For what purpose?

With ATI-tool 25.11 it's the 2D clock you up, but it's automatically in use when you open the ATI-Tool, look on message appears when the soft launch.

SIOUX i'm coming for you http://www.xtremesystems.org/forums/...8&postcount=28 :D

Why not to use ATi Tool for setting clocks? Why use ATi Tool only for voltage? Does "overclocker" tool do something differently to clocks?

still X1800 Oc tool is better for me

i.e. looping ATI Tool beta 11 'show 3d' stress test.

oc'ing using ATI Tool beta 11 max = 762mhz at 1.45v and locks up higher

but using good old method of X1800 Overclocking tool for clocking max i get so far is:

GPU
783mhz at 1.5v
789mhz at 1.525v
796mhz at 1.55v (gpu idle = 46-47C and gpu load = 51-52C)

When I type in clocks in overclocking tool, it doesn't change. In fact, it drops to 480mhz...

you disabled ati services ?

Yup... services disabled... When I first time ran overclocker, I could change clocks, but past a certain number and the clocks wouldn't actually change... Second time I try overclocker, nothing changes right... ATi Tool 025b11 works good for me though.

I gongratulate you,for your working and benching about x1800xt....

It may runaway my eyes,,,sorry...how much did you give vddc and vddq??

2.034v for both i used:)

Here are some pics of the cooling, that somebody asked for:)

woah heavy duty there :)

ok, this might be the ultimate stupid question, but i just have to ask it anyway :)

what did you two (eva & sioux) get on stock cooling with stock volts (1.275/2.0)
as max clocks for gpu & ram via atitool (whatever version?). because i figured
i had the two bummeresque cards ever. one did 637/792 and the other could
only get to 635/757 (maybe 765), both club3d x1800xt 512mb cards... ran in
the same system even...

Well stock volts is actually v1.300 on the core. I myself can't even remember what I was getting on mine at all...

ati tool suxs never used it for oc'ing even 601mhz gpu would give me a blank monitor

you can see my ocs at http://www.xtremesystems.org/forums/...hlight=X1800XT ended up around 689/797 in CCC and 688/801-830 in X1800 Oc'ing tool. At 1.375v GPU stock volt of mem allows my mem to jump from 830mhz to 882-900mhz
