Software volt adjustment?

post #1 of 16
Thread Starter 
Is there a software to adjust the vcore of the CPU? My mobo BIOS only supports up to 1.5875, which limits my overclocking even though I have good temps.

Not that I know of, if its not an option in the bios then I dont think you are going to find a program that will adjust it for you. However if you were to mod the Vcore with a Variable Resistor, you could run as much voltage as yould like. I just dont think it would be worth the effort on that board, Id suggest buying a new board. P4P800SE is a great overclocker, and chances are your CPU would run out of steam before the board would.

I suppose you have reviewed the shuttle website to see if your boards bios is the most recent. Sometimes you find that later revisions increase voltage ranges.

Northwoods do need a bit more voltage than you specified if you want a big overclock (look at my sig for instance @ 1.625v VCore)

You do really need another boad if you are after big overclocks such as the P4P800, P4C800 or IC7 which support greater voltage ranges.

But no, there is not any software voltage progs that i know of i would seriously suggest avoiding it if you do. You might burn out a capacitor or two if your not carful. Thats the reason why boards that have large voltage ranges have oversized capacitors and power regulators.

Sorry i could not be any more help

Ok, I will probably look into a new mobo then. What is the difference between the ASUS P4P800SE and the ASUS P4P800-E DELUXE? Are there any other cheaper alternatives that allow for great overclocking options?

Mostly features. The Deluxe has 2 extra SATA ports, firewire, and better sound. I guess that's the main differences. Same chipsets. Check here, and pick both boards to see them side by side:

I think it is to do with the number of SATA controllers and such.

They both use the 875P chipset, i believe the deluxe version is slightly more stable, but apart from that there is no disernable differences.

Also worth looking at the Abit range of 875P Chipset boards like the IC7, IC7-G and the IC7-Max3

These are as good if not better imo than the Asus boards. (not that i am biased )

The chipset is the 865PE. I don't think ASUS manufactors 875 chipsets anymore. However, my P4P800SE runs great! Solid, decent performance. Currently overclocked my Northwood from 3.0 to 3.6 GHz without any voltage adjustments. When time, I will go higher.

Also, be careful that you don't go too high in volt. There is a thing named Northwood Sudden Death syndrome, which comes into play at around 1.7 V (I believe)

Good luck

Your best bet is to wait around until someone is selling one used for a good price. I see those boads going from around 50-70 all the time.

Wu, get one of the p4p800s, best investment I have made so far. Someone sold one here last week for $55. You can run your Northwood on it and will take just about any socket 478 you get your hands on.
