Prescott wont boot over 1.6v

[Rancidelephant]

Hi all,

A little help please.

Prescott 2.4a
P4C800-E 1016 bios
2 x 512MB BH-5
400W sparkle psu
9800pro

Runs fine @ 200FSB but when i used clockgen to increase the fsb i got a blue screen. Its currently undervolting 1.6v --> 1.49 so i went for 1.7v, hah no .... cant boot anything above 1.6v.

Any better bioses about anywhere or any other ideas ???

Thanks alot
in advance

i heard some manufacturers limit the voltage their boards can feed to prescotts because they are affraid it kills the cpu or the voltage circuity on the board.

...so try an older bios, maybe that helps.

Is a prescott 1.45V standard??? Cant you OC from BIOS?

[cold_ice]

Thats a known issue on Asus boards. You could do the vcore mod, or buy a IC7. It's the best for prescotts

have over clocked in bios.

prescott support was added to 1016 bios so i cant use an older one .... and there isnt a newer one i dont think.

got an icz here as it happens

cba putting it in the prommie tho

mabe will try it before i play with the 3.2c i have.

try the prommie first, i think 1.6v will already get the prommie to pretty high temps

I think the MSI wont let you go to high on the volts. I've put 1.75 into a prescott with my IC7

Its a problem on the Asus and Dfi Motherboards, on the Abit IC7 Max3 i can give more v-core.

A older bios version dont help.

I read somewhere that using the BIOS that comes with that board allows you to go to Northwood voltages on the Prescott.

Don't know if its true though
