Thread Starter 
- Hey guys, i have an ASUS EAH Radeon HD 4670 1GB GDDR3 and im trying to overclock memory from 800mhz to 1000mhz but still when i set 1000mhz i got a pixels on desktop but on 975mhz it runns just fine, i have tested it with 3d mark, furmark..etc without any problems, so why i can't pass to 1000mhz clock ?

i like that card
maybe you hit a wall with that card or maybe it needs an increase in volts.

how can i increase the voltages ?
post #4 of 6
Most cards will need a hardmod to increase memory voltage.

200Mhz on the memory is quite a bit for that card, and you should not expect such an OC to come easy.

i had a visiontek 4650 512mb. I tried like heck to overclock it and all I got was artifacts, Blue screened, and no video sometimes.
I looked at pencil mods...where put some penciling on the card memory but I decided against it because I wanted to use the card for a 2nd rig...media PC.
If your card doesnt have or list features like increasing voltages than you most likely can't do anything more. Try to get ASUS latest overclocking software for your card and if thats no help than its time for an upgrade. ASUS has got some good hardware out right now. Or pick up a 4890 then your all set.
