why can i only oc my mem by 10 mhz?

[klmico]

I just got the 100 dollar radeon 8500 from newegg clocked at 250/275. the crad is working great but i cant seem the clock the memory any higher than 285. right now i'm running at 285/285. anything above a memory clock of 285 will give me really bad artifacts and mess up the whole screen. im runnong on a:

p4 1.6a @ 2.13
msi 645 ultra
samsung 256mb (oem) pc2700

does anyone have any solutions for me to get up to 300 memory clock? im using powerstrip btw.

Try this:

1. Close PowerStrip if its running
2. Use Notepad to open the pstrip.ini file in the PowerStrip folder
3. Add the following line to the [Global Options] section:

[Global Options]
SpecialTiming=1

4. Save the file back to disk
5. Restart PowerStrip

thanks for the suggestion but that didn't quite do the trick.

Ugh.... looks like one of the memory chips on your board is flaky. Remember, one flaky chip brings the whole card down.

Could be bad memory. Could be heat.

I installed ramsinks and crystal orb on mine yesterday and tweaked a bit this morning.

With ramsinks, memory flaked out at 340MHz. With crystal orb, gpu flaked out at 300 Mhz. Scored 3DMark of 9295 at 295/335 core/mem at 146MHz FSB (KR7A/locked XP1600+/98SE). Seems game-stable at 290/330 (9225@290/330).

No voltage mod or BIOS change.

Hope this helps!

Heat is a very low factor for memory speeds. Transistors (opening and closing of gates) is affected by heat much more so than memory (capacitors holding a charge).
