Spoke to XFX the other day. They said normal operating temps for the card are 50-60c idle and 70-85 under load. They said no core slowdown is expected at anything under 100c. My cards run just within those specs (60 idle and 85 under load in SLI, 55c idle and 75c under load without). But the stuttering occurs even at 60c.
I can't say I'm glad it's not the X2. If it were, I'd only be $282 in the hole for the single core processor. Now I've gone and replaced my motherboard $110 and now ordered a new graphics card $450. If my wife finds out about this, I may never get to post another message here again.
What scares me is that virtually nobody on the internet has the same problem I do, including the myriad of complainers on the XFX forums.
Also from my experience overheating causes choppiness and lag. These are things I don't have.
Well I don't know if I posted this before, and I'm too lazy to check, but I reinstalled with my old amd 64 3200+. I am using the exact same drivers and getting zero problems. The only thing that I have different is the bios on my motherboard. I reverted to the original version of the bios that does not support dual core cpus. This leads me to believe this is either a problem with a) ASUS bios, /cool.gif' border='0' style='vertical-align:middle' alt='cool.gif' /> the chip.
I just find it strange that I'm using practically the same set up aside from the bios and do not get the problems. I didn't have the problems running on a newer bios either when I tested that.
When I had the problems, I couldn't just "tweak" my games to get them to work. There was nothing I could do. The only time I noticed the problem was in games because they constantly display something, but I'm sure in other programs the same issues were occuring, I just was not able to notice them. I tried every possible bios/driver combination on fresh installs of winxp when I had my dual core, nothing worked. I suspect that in the near future newer drivers will be released that can fix some of the issues. I'll be trying a dual core again near christmas.
just to let bp1019 know i have the same problem in games and also when i had multiple users setup in xp but when i did a new install of xp and only had one user i dont have that issue anymore but i still have the game issue so im thinking it is not just a game thing i have also found articles about how it is an ACPI issue and if you switched to MPS it has fixed the problem.
ASUS A8N SLI PREMIUM AMD 64 X2 4400+ NVIDIA EVGA 7800 GTX OCZ 2 X 1GB
UPDATE: My stuttering problem was being caused by my MONITOR. It is a brand new Envision 20" LCD model #EN2028. The stuttering occurs regardless of whether connected via VGA or DVI. The stuttering does not exist when tested on a Viewsonic 21" CRT and NEC 17" LCD. It is being shipped back to the manufacturer today.
Thanks, Envision, for ruining my entire month and for making me replace every part in my computer.
Anyone want to buy a DFI NF4 SLI-DR motherboard, AMD 3800+ or EVGA 7800 GTX?
