Bios Flashing 7800 and OC to 500/1000Mhz - Page 3

Ok maybe you should stop,
My system crashed and got a blue screen doing 3Dmark test
so maybe it is not worht all this work after all

peter-pan
are you using any kind cooling?

what dos version are the succesful people using?

wherer can i get it?

I used the one that i gave the link to

Ok I get it... it can't recognize anything higher than fat32 which I have no partitions of. Writing to that is. Ah well. Sorry to hear about the crash Cyber

I am changin back
the GPU gets to hot when i play Need to Speed unwanted
it get all the way 92-93
and i am not gaining so much speed any way

I'm already scared that my videocard will die with my oc to 312/821, doing this would be too much for me X_x

400/880 3d 05 in progress....

Found the usb drive. Cheers cyberman

The big issue is the cooling solution is inadequate for this voltmod. I have ran every notebook and GPU on the highend Dell has made over the last 3 years (not big timing anyone. Just giving a point of reference that I am not an ignoramous spouting nonsense). My 7800 GTX Go on my XPS2 would get up to 82 degrees C WITH both copper Heatpipes and AS5'd so there ya go. This is an accident waiting to happen.

Personally if I get 5500 ish oc'd without the voltmod I will be pleased as punch. I will know more tomorrow when I get mine. Not worth the extra 4-5 fps for me to do this voltmod and really if you have any common sense about you (not talking intelligence here, A lot of people on here smoke me in that department I am sure) you will skip this voltmod.

Seen desktop 6800 GT's go up in smoke in 4 months using the old bios flash to 1.4 v to make them 6800 Ultras. People forget the cores may be the same BUT the PCB and cooling solutions are different. For me, if the 18% increase in voltage gave me more performance I would do it. But we are talking more like a 12% increase in performance assuming a score from 5500 to 6200ish. Risk does not= reward(for me).

You do this at your own risk and really people, even with a HEAT mod the PCB is clearly different from the pics and it is not rated for this voltage. You really should skip this one. These are not desktops, and people that tend to do serious overvolting do not do so on lappies. They do so with watercooling and tend to turn over chips quick(say every few months) I LOVE mods but this one makes no sense logically for the longterm use of your laptop. Just my two cents...

Maybe the clock speeds were a bit too optimistic?

I'll still try it myself, just have to buy that AS5 and lap the old sink.

Maybe my math is off, but isn't a .02 volt increase on top of 1.11v less than 2% overvolt?

1.1v to 1.3v is a .2 increase or 18%.

I did it again, this time did not go above 450 and 900.
it looks like the only thing stoping this show is the heat.
does the XPS heatshink fit on 9400?

cyber, are you using fangui? Probably obvious, but run with both fans at max speed.

LMAO, you're absolutely correct. There's a big difference between 1.11-1.13, and 1.1-1.3. Sorry! LOL.

Im at 450/880 as well. Ive got 83.60 drivers and they suck for 3dmark. Upgrading to .90 now.

Temps got to 92deg tho...

Hey! I always knew this would work! Props to you Peter-pan for having the balls to actualy do it!

So what are the word on temps with AS5?

If you care about your $300 7800 go, then do not do this mod.

I'd pimp 375/900, I'm pretty sure that would be safe for this card.
