oc decreases performance

[thenerd]

my 9600xt oc'ed to 510core 325mem gets 3600 3dmark 2k3 score. if i go 500core and 325mem, i get 4050 2k3 score. wtf?

 

[thenerd]

i just did it on stock clock, 500/300, and i get 3900 3dmarks!

im using the overdrive feature with the 4.9 catalyst drivers and it overclocks it to 526 and default memory

what program do i use to overclock it manually?

ATi Tool

I prefer Radlinker for OCing, personally..

heres my 9600xt

default settings: 500/338

3dmark03: 4141

overclocked: 525/345

3dmark03: 4236

 

[thenerd]

well u got a pre oc'ed 9600xt then...

anyways, wtf, oc'ing is compltely failing me. i just got another 3600 on 3dmark 2k3 after setting my clocks at 500/329. man perhaps it is ati tool thats casuing this problem? or 3dmark?

Same here. That's what my second rig with the X800Pro uses.

 

[thenerd]

does this have anything to do with agp fast write? i have it on

 

[dandragonrage]

Turn fast writes off in your BIOS. It doesn't really effect performance, but it can effect stability.

 

[thenerd]

it affects stability for the better or for worst? and i read on tom's hardware that agp fast write can increase 10% performance.

On my 9600XT when I would overclock it my frame rate in counter strike dropped drasticly.

Don't believe everything you read, especially from tomshardware.

Well put.
