Hi there, I recently got a new MSI x1900 XT graphics card. I run with 1 GB of ram, and an Athlon 64 3000+ at 2538 mhz with the stock cooler.
I have 2 80 mm case fans in the back, along with one on the side of my case.
I first ran up the card and some atitool 3dcube and found that my temperatures were quite high up to or over 84 C. I couldn't really overclock the card at all. Replaced the stock thermal junk with some AS5, and now my temps cap out at 78 C or so looping rthdribl. I was able to overclock to 658/769 currently.
I max the fan at 80% because its too loud otherwise.
I have 1.1 ns ram on my XT but I am getting poor memory speeds. One thing I found was that with a 500 mhz core, I was able to overclock the memory to 801 mhz at temps of 69 C. However, as I approached 650 core, the temps would go up and I'd get checkerboarding unless I lowered memory clocks. My guess is this is heat related? And why does this 900 mhz rated ram do so poorly when my old 6800 GT ram could do well over the rated spec?
I've also tried playing around with the voltages. Currently I use 1.425 Vcore which I have read is the highest I should go on the stock cooler. I find that bumping core up to 661 causes it to stall; should I increase the Vcore to 1.45 and try again or leave it as is?
Also with the memory: I increased the VDCCI to the max 1.58 V, and this really helped and allowed me to clock up to 801 mhz. But I found that changing the memory voltage didn't help at all and infact I could lower it and still be stable.
What should be the next step I should do? I'm trying to get the most out of the card and hopefully reach something closer to the 675/800 most others seem to be getting.
I am getting 10600 3dmark05 at the moment.
