OC the 8400GS DDR2, What is the fastest?

[anakuper]

hello, i`m new to OC 8400gs DDR2..
my stock speed:
core/shader/mem = 400/800/400
i`m already installed 174.31 and riva tuner... winxp
please tell me, what highest OC and good stability your card can go???

sorry, if the topic already discussed, please point me to the thread...
---------------------------------------------------------------------------
update new report on 8400gs ddr2 174.50:
on stock 400/800 3dmark06 got 1414, temp 73`c
on oc 500/1000 3dmark06 got 1608, temp 73`c
on oc 600/1200 3d mark06 got 1816, temp 74`c
pretty lame isn`t it??

You just had to use the search button you know..

whats the safe overclock range for 8400gs DDR3?

8400 GS owners- What are your 3dmark 06 scores?

Also my OC is on my sig below. Just make sure you know exactly what you are doing when OC'ing. You sound eager to watch your notebook explode

flipfire forgot to mention that his video card has DDR3 which is the only way his mem can hit 750. My DDR2 wont even hold 490 without a problem. The highest I have been able to get is 650/1600/485, but I might be able to push it a little more.

I did some in game tests with different clocks on my gt and what i discovered was that oc'ing memory showed 0-1 fps increase(adding 200mhz) shader showed 8-9fps increase(+300mhz)
Cant oc core higher than shader for some reason :? But basically it added 3fps (+150mhz)

Highest mine went was 600/1200/800... ddr2 and you upped your shader to 1600mhz!?!

If you dont mind me asking... What are your temps like? and what increase do you see in-game? Thanks

i`ve already OC my machine to:
1. 433/866/433
2. 466/932/466
But the strangest thing is, when i`m try to push the slider to no-same-ratio OC like: 451/800/451 apply and OK, the slider just coming back to original, is there something wrong?

btw, how you can get that 650/1600Mhz number? the highest on slider is 600/1200..

And of course i`ll not let my lappie explode, i`ll try keep the 467/934/467 as my startup 3d performance OC..

the card may appear stable even at 700/1400/800, but watch your tempture. i tried to over clock my 8400gs ddr3 by only 100mhz core/mem. temps are hitting 100C. so i had to turn back to stock. and I think ddr2 is less overclockable that ddr3

Ive managed to completely max out all the settings at 600mhz/1200/800mhz with no artifacts but the temps reached 86c. I rolled back, probably will never use this setting again but its good to know what its capable of. I have the ddr3 version

I got about 25fps more on CS:S and around 15-20 on BF2. Only 2000+ points on 3dMark06

i have oc regulary with 467/934/467, and the max temp 63`C
is it wise to go up again? what the danger temp can damage vga? 70`C? or 80`C or 90`C..?

Try not to go over 80c
