8500/8600/GT/GTS Mod guide...

well in this case it is a driver problem when you modded the bios did you remember to put a name to the card in the bios editor? like did you select it from the dropdown list and pick your card? also if you did remove your drivers reflash and boot back up and install....actually wait for wondows to install its own. then install yours.

 

[BrooksyX]

Yeah im pretty sure that I picked the right info for the card. Ill double check when I get home and make sure to uninstall before I flash and reinstall after I flash. I also flashed your risky.rom bios and windows couldn't find drivers for it but it seemed to flash just fine.

If I upload my old and new bios will you check to see if I messed up?

 

[Solaris17]

ya sure NP ill look at it

 

[BrooksyX]

I was about to go crazy last night because my internet was down

Anyways here is my original bios and my modded bios.

 

[Solaris17]

no your bios looks fine you may want to put your thermal critical at 100ºC though the card reaches 80 pretty fast and that may be faster than the fan can spool up to cool it which means your card will shut down regardless...but ya set that at 100 reflash make sure the drivers are deleted in the c drive after you choose to uninstall them...then flash and reinstall drivers then reboot again and you should be good.

 

[BrooksyX]

Oh well I have an Accelero s2 on my card, so there is no fan anyways. I went ahead and just flashed the card with 660 on the core, 1512 on the shader, and 800 on the mem. I didn't change the performance levels or the voltages and it seems to be working fine. I wonder why it won't work if I change the other stuff. Maybe I should try the omega drivers.

i should be getting a XFX 8600GTS XXX and will be custom cooling it will these mods work?

 

[Solaris17]

yes the GT and GTS pc'bs dont very much if at all and these mods apply to both.

 

[cdawall]

yeah i wonder if i can out do your old 8600GT

 

[Solaris17]

hahaha what hubris a mere man taking on a god but amuse me i will accept your challange!

haha we will see the only advantage you may get is your cpu+ram seeing how mine will be on a DDR1 and single core system

I like the RivaTuner, good fan controll and clock controll, but how much is too much? Do you just watch the temps? Just by boosting the fan to 100% mine dropped 4 degrees. Any suggestions on clock settings or operational temps?

 

[Solaris17]

you just watch temps really cut off is about 70ºC if it gets that high your getting to hot...then you move on to other methods of cooling or you lap your heatsink.

 

[cdawall]

@sol what do recommend a custom cool setup which would consist of an old socket A cooler with 60mm fan for gpu and cut up HS for the ram or a zalman VF900cu?

 

[Solaris17]

if you can set up the old cooler to fis in all the wholes ok and your SURE you can cool the ram that id just go with that...lap it and make sure all the holes line up the pcb tends to flex thats why im concerned...also if you can id reccomend cutting a few small squares and putting them on the fes in the back...those get mighty dangerous hot after a volt mod.

 

[mlee49]

Awesome, I'll wait till I have some better thermal paste before pushing the limits. I'll post some pics w/ the oc.

 

[Solaris17]

sweet do it i want to see.

thats all the gpu cooler will be its about a 3.5"X2.5"X1" and would the little black one be ok thing on the back?

 

[Solaris17]

ty to cover all the big black chips.

 

[cdawall]

ty to cover all the big black chips.

what all needs to be covered?

 

[Solaris17]

here

 

[cdawall]

well that should be easy i thought i was going to need to cover like the whole back or something

 

[Scrizz]

my XFX 8600gt XXX pcb is different, the fan/heatsink only mount w/two screws.

 

[Solaris17]

here you go scrizz...

orig is your fail safe
modded is a lil better performance
risky really good performance not that risky and if i remember correctly youll need a vmod to go higher....uninstall your drivers b4 flashing. reinstall when flash is complete.

 

[mlee49]

Hey I cleaned the heatsink and chip and repasted. Also tweaked fan up to 100% and tried to max out settings, but I can only oc like 5-7%. Do you think I need to do the volt mod? Its a OC edition so maybe its already maxed out and Rtuner cant push it any further.
