877mhz memory on x1900xtx with stock MVDDC :o

I could get my memory up to 846mhz on air (cheapo heatsinks under HR-03) with stock volts before hitting a wall from heat. After getting my EK-FCX1900 I had the same problem at ~851mhz because of a crappy mount. I redid the mount and put some pressure on it and now look :banana: :banana:

Memory is BJ11 week 604 IIRC

I did have the VDDCI at 1.5v, I'm not sure if that had anything to do with it though. I'll post some 3DMark screenies later. I am hoping 900mhz+ with some decent volts :D

Ok, "I think" that memory goes upper better with stock-voltage (2.086V) and activ air-cooling. My X1900XT was OCing better by memorys when I was set under stock-voltage (for Example 1.995V) to memory. Just don't know why, but that's true. undervoltage was better with my card. sounds grazy.
801/868MHz (http://koti.mbnet.fi/boble76/Tietokone../X1900XT/14160.jpg) with icewater on GPU, air on memory, no heatsinks.
Hope you get that 900MHz.

Nice clock :)

Bad news! I played some Starcraft and about 15 minutes into the game, I got a checkboard/squiggly screen and lost my video. I figure "big deal, unstable clocks after all" and rebooted. Ultra-D reported 2 LEDs, :banana::banana::banana::banana:. I reseated the card in the slot and the board gave me 1 long and 2 short beeps, referring to a problem with the VGA. I slapped on the stock cooler and no go :( I guess its time for an RMA, at least I can say that Starcraft killed my x1900xtx :wth:

Same here with me X1800XT. Best mem oc with voltage for mem stock or even a tat lower and only increased voltage for core.

lol.. there goes the story of the x1900... Could be a heat issue anyways.

As for the clocks, xtxs dont have a problem hitting 850MHz+ on the RAM, not to mention that a higher vddci makes a huge difference as well.
