I used 1.52/2.151/2.119/1.510 to get my X1900XT (BJ11 rams) to 702/801 rock solid.
With modified stock cooler (replaced fan with 80mm fan) I max out 72C core, 56C memory under hours of Farcry/LostCoast/AArmy.
With the STI services shut off, Im in "3D" mode all the time, dile is at 48C.... is there a way to get back the 2D/3D control while keeping ATI tool profile in effect for the 3D numbers? Im using the plain Control Panel, not CCC, from the FireGL Cat 6.3 package.
wow, I guess the XTX cores really are stronger. I can get 685/792 with 1.400v flat. Seems like a very small jump for 7mhz core and 9mhz ram for an extra 0.12v.
I can imagine too this: 772/891 1.475 on core.. stable no artefact, i can easy imagine there's a possibility to go higher if the memory is not OC..
You must make and save a 3D profile in ATI Tool, then go to Settings -> 3D detection. Enable 3D profile when 3D app is running, then back to Default (or a 2D profile if you want, I made one undervolting a bit) when 3D app closes.Quote:

Made two profiles... FAST and SLOW. Slow is like default, and fast is all the top settings.
Dont know what Im doing wrong though. Just vertical lines on loading SLOW, even though I boot to SLOW at windows start without issue.
I just set up several profiles one i label 2d ,3d and bench. You need to disable the the ATI hotkey and smart services. Then set up your profiles. You will need to adjust volts and fan speeds for each profile. This is how i set mine. Good Luck and hope this helps.
Has anyone tried flashing a Crossfire X1900 Master to XTX speed? I have one incoming and was considering going for it. I downloaded a BIOS Tuner by raBit to play with doing edits, and it only allows access to 2d clocks, or they are what shows up. meh.
I don't get this strange way of oc of x1900 series, why 4 voltages and why the hell does it freeze when I up frequency using latest ati tool :slapass: I am sick of this freezing, always restart. Maybe I should not use artifact scanner. I've oc so many cards but here I am feeling like complete noob :D
after you disable the two services required for running atitool, you need to raise the voltage (the top one first)Quote:

after you disable two services, u need to raise it to this:
1.45/2.086/2.086/1.486
1.45v is the stock voltage in 3d mode for these cards.
and after you raise the voltage, then you can change the clock speeds (start at 650/775 if you have xtx, 625/725 if you have xt)
Played around a bit. I can bench @ 760/900 on water, 1.575/2.35/2.151/1.526
Oh well, I expected closer to 800 on water. I think it loves vcore :D Will try mounting my vapo on it :)
Only the core was cooled by water , or the mems too?Quote:

I'm not sure how the VDDCI comes to play with Intel mobos, but it does increase my mem ocability when I increase it. Where did you get info on VDDCI and ATI Chipsets?????Quote:

I seem to have a comparatively good core- running 680MHz with only 1.35v. I haven't tried further yet, just tried a healthy 55MHz OC with under stock volts and I've left it there to play with the RAM.
I can't seem to get mem to run 750 even.. with 2.0/1.9v on the RAM/buffers. I've still got VDDCI on default, as I've only started playing with it an hour or two ago. MVDDQ doesn't seem to affect the OC at all- I can have it at minimum 1.785 and it still gets all the way up to the 750MHz ceiling :confused: Mem voltage optimal seems to be somewhere in the middle of 2.0 and 2.1 lol haven't fully tested yet
I managed to get my core to 720 with vgpu 1.500 and my W/C. It can probably go higher with more core voltage ..
With memory though I'm having issues with anything beyond 792.. I tried many settings for VDDCI(<1.52 though I don't dare going higher) and different combinations for both mem voltages. Nothing..
Using a GeCube X1900XT and W/C with aluminum ramsinks..
Probably a crappy mem controller :nono:
Any ideas on what else to check to see if I can increase my memory o/c?
P.S: I have BJ11 ram... Thanks
Hey guys, I got my X1900XT to
669/774.
1.450.
2.201.
2.102.
1.550
Does anyone have any tips to get it higher? I cant go over 670 cause when I do FEAR just crashes. It gets to 75 celcius max.
first tests:
Powercolor X1900XT
stock-cooler:
729core 828memory
1,475V,2,099V,2,099V,1,480V
i also get load temps higher thab +75C
Hey, how come you get to 729/828 and I only get 669/774. We are not even so far appart with the voltages.
Anyone care to explain why everyone is getting higher clocks then me :P.
some cards can clock better than others... also i noticed when my temp is going up to 80°C its suddenly freeze...
so better temps will help i think.
update:
with watercooled rig:
1,575V-2,250V-2,080V-1,561V
783 core / 891 mem
