to volt mod the 7800, fire up NiBiToR 2.5a and change the voltage for the 3d part to VID Mode 6 to VID Mode 7. This gives you a voltage boost and let me increase the vpu core from 450 to 470. While you are at it, you should lower the...

My memory maxed out at 1300mhz, so I dropped the ram timings to gain a couple of hundred 3dmark points.

Penguin, don't spread FUD. All 9300 motherboards can take a 7800gtx if you follow the instructions on the forums. There might have been an early northbridge heatsink on the i9300 that hit the 2nd heatpipe on the 6800U and 7800GTX cards,...

Nice to hear meltdown! Now start overclocking that thing when you get it, I'm over 7600 3dmark05 and trying for more right now. Check my other thread for overclocking/ overvolting tips. I thought about ordering a dozen and ebaying...

Why would you not modify memory clocks? Everybody spends uber money to buy low latency memory for their pc. Lower the cas from 3 to 2 and your pc gets faster. Same with the graphics subsystem. The danger is in raising the voltage....

I was able to increase the voltage on my 7800 gtx using NiBiTor 2.5a Open your bios, click Voltages, and then VID Mode Click Voltage 2 and change from 6-1.3 to 7-??? Now go back to exact mode and it will show VID ...

UPDATE 1/27/06 I hope you all got in while it lasted. It appears that the low price is gone, and both part numbers are now at $599. Good Luck! Time to let this thread die Original Thread I called Dell USA spare parts...
