Unlike SLi, in Crossfire each card has to be OC independantly. BTW that's just one CARD I haven't removed the HSF for the other one, but been the same exact model should be the same, I hope. I gonna have to remove the HSF anyway because I need the replace it with a Zalman VF900Cu. What the brand of your X1950Pros?Quote:

If things were to work properly (I say this becasue even with ATiTool25Beta14 things aren't working as I though they would) with ATiTool you click on settings and you'll see that you can switch cards and then OC each one individually.Quote:

Edit: Also, I did measured the voltage for the gpu and memory. Both measured @ 1.4v for the gpu and 2.08v for the mem. Which tells me that we should get some moderate OCs of these.

read this article. it's interesting.

Dude I tried every possible combination. I think the problem lyes in the Digital PWMs...:mad:
So... we still waiting for better driver support on these?
BTW, anyone get why ATI cards are more expensive then
ASUS or Sapphire variations?
Is it just the name sake?
CATS 6.11 work quite well, I just think because they have Digital PWMs might hange things a bit and a unique OC proggy may need to be created. As far price variance, well yes it's just the name. Remember the Sapphire makes the PCB's for ATi.Quote:

I know you can do this. plenty of people have overclocked this card in crossfire mode. did u check google for saphire x1950 pro reviews? maybe you can find some tips?
Yeah, absolutely over 700 Mhz on core would be great, as these run so cool!Quote:

I bought the sapphire version of this card last friday, takes up 1 slot..
It clocks ok on the core using rivatuner, but ram wont budge.
Like was mentioned at the start of the thread, I get odd results in 3dm01.
Sometimes hit 28000 points, sometimes 31000 points. Re-running the app straight after the 1st result is shown.
Must be a driver issue as these cards are still new-ish. Im using the latest 6.11 drivers.
Seems a low score for a 4000+ at 3.1ghz (250mhz@ 7,2,2,2), dfi ultraD.
Im about to reinstall windows as its corrupted, will try again tonight.
What's up fellas....I experience some of the same issues described here. I FINALLY was added to the forums woo hoo. I can set the clocks in Overdrive, but when I go bench with 3dmark, the screen goes black. On top of this, I can't even get the card to clock past 594 MHz without the same result (black screen). I've tried turning off VPU recover too. I ordered a VF900 Cu from newegg.com today, so this may help. BTW Nicepun, love the avatar! I really just wanted to collaborate with you guys, as I see that there is a good convo going on here about our cards and whatnot.
Also, when I set the clocks to 594 MHz, I have had games crash at even this clock.....it is the heat I'm pretty sure, because when I go to the 3d renderer in ATI Tray Tools and scan for artifacts, the temps will climb until around 74, and I've even added Arctic 5. I have a stock HP MOBO, and the stock case, so could these be the culprit? Nicepun, let me know what your temp ranges are if that's cool......usually I idle at 47-8C, but I left my heat off while at work, and I'm idling now at 40C! The environment temp is 35C. I usually load on games at max 65C, but I can get higher when I heat the card up via ATI Tray tools artifact scanner. Anyways I'm tired of typing, just a lot of stuff on my mind.
Peace out, and looking forward to being in this forum: looks like a good one.
Hey I have read that some of the issues are due to the VRMs overheating read here:
http://www.sapphiretech.com/en/forum...3506#post53506
starting at post #123
Well so far I've been able to do 621/1512 on both cards (using ATiTool25Beta14). Anything more on the mem on either cards and system freezes, anything above that on the core and I get same results. I'll be posting results tonight after I put my daughter to bed.
Hmmm...I have NOT had the probs you all are describing. I have the Sapphires running 6.11 Cats with VF900's. I do GPU folding all day long & my cards never exceed 45C.
I can OC the core to 621 and mem to 766 & it will run thru any benchy without crashing or locking up. I use CCC for OC'ing...I bought these awhile ago when they 1st came out. Sorry to hear about the probs you are all having. Nicepun...I am interested in your results. My CF seems to be running problem free.:toast:
I will get back with you guys when I install the VF900 Cu and let you know....my temps are idling at 44C now. I don't know if this is becuase I put my air filterer behind be PCs exhaust, with the horizontal intake sucking in the PCs exhaust.....didn't think that it would make a difference but it apparently did. I'm about to order some ramsinks for the VRMs, I don't really need one for the memory but the core is the one that is overheating and making the black screens over 594 MHz, which is super lame.

idle for me at 648/830 is 42c using the stock asuis cooler
its definitely your load temps on the single slot cooler. get that VF900 Cu on there asap
I have the same problem too. I've just bought a sapphire x1950pro card and I'm using 6.12 beta drivers and when I try to overclock the memory on the Ati Overdrive memory clocks stay the same. I' tryed ati tray tools but it only decreases memory speed (I think it has a bug due to ddr and ddr3 contage). On ati tools 25 beta 16 the system freezes as I increment 1 mhz on memory. There is no problem overclocking the core but I can't figure out why memory can't increase:( .
btw- my temps are 38º idle and 66º full
Here you go with a few tweaks....LOL

Nice! you did it! what is each card running at?Quote:

funny thing here. I can raise card A to 641/823 but when I try other card using winclk it pushes the clocks down on card B.
maybe I should try the ati tool again. brb
Each card is @ 621/1512Quote:

You fellas using Winclock: how do you get it to set the clocks on Windows startup? I didn't think that you could.....I sent a support ticket to Sapphire requiesting the heatsink for the VRMs, they didn't include it on the regular X1950 Pro, but they have it on the ultimate.....they better give it to me! SO many other people are having issues with this card overheating and the black screen. I guess Nicepun has some good case airflow, assuming that you don't have any heatsinks installed on the VRMs.
u don't.Quote:

Ouch, that sucks....I'm sticking with Overdrive until I get my VF900 and some sinks for the VRMs
Nice job nicepun, I am interested in 'your tweaks'.Quote:
