ati 4670 intermittent drop in frames

blinkage182 · 12-13-2008, 02:27 AM

i'm new to this but i just bought and asus EAH 4670, which is the ati HD 4670 and i'm experiencing intermittent sections of lagging while running 3d applications.

i have AMD x2 6000+
2 x 1gb corsair 800mhz
asus M2N-MX SE plus

while running fallout 3 it's running on 1280 x 800
4 X AA and 8x antistropic filtering
i can get an avg of 30 FPS but about every 2 minutes, the frames drop to about 5-15 FPS and stay like that for s further 2 or so minutes. even on low settings and 1024x768 resolution same problem occurs.

The same happens in crysis on 1024 x 768 on medium
i get about 40 FPS then a drop to about 10. any advice or help would be more then greatly appreciated.
Thank you in advance

First I would try uninstalling your drivers in add/remove programs. Reinstall your drivers. Consider a PSU issue! http://www.silentmods.com/modding/PS...alculator.html

i was concerned about a power issue, so i'm actually going out soon to get the corsair VX-450w which has 33a on the 12v rail so if that fixes it then i'll be happy

Good luck with that. Is this PSU going to be enough for your setup? Did you try the Calculator?

yer i did the calculator this should be good my PSU now is 18a on 12v and runs everything no problems except for when i start a game up, the extra power should do good
