Safe Voltages?

post #1 of 11
Thread Starter 
Hello happy AMD'ers tis' me again =]

I have my CPU @2.85-2.80GHz and sometimes it crashes then wont reboot with the overclocked settings

I was wondering if i need my northbridge voltage higher, im using a gigabyte S-Series Nforce 550 Motherboard

What would you reccomend voltage wise for the CPU, HT link, CPU HT Link and chipset voltage?

[Whats the max chipset voltage do you reccomend?]

Thanks =]

Trying to get higher then 2.8/Keep 2.8 Stable, would really appreciate advice, my chipset / CPU has good cooling, so temperatures arent too much of a problem

Here are BIOS screenies of me current CPU/RAM settings, thanks.








Hopefully we can get thisbadboi higher/stable ^^

im talking about CPU
i wouldn't think you'd need anymore voltage on anything else at this stage i mean it's not highly overclocked ... is it orthos / prime stable ?

I don't know if this applies but I'm at 3.05 GHz rock solid on for several weeks:
Gigabyte GA-M57SLI-S4 & AMD X2 4800+
by lowering multiplier to 10.5 and HT to 4 & FSB =290.
Orthos temps = 57C on air (But in chilly lower level thanks to Minnesota winters)

Haunt, at 250HTT I doubt you need to raise the HTT voltage. If you do, just raise it up a point until it's stable. Make sure you have proper cooling on your chipset first. Have you played with your memory settings yet? Brisbanes can sometimes be picky about the settings. Try these changes and see if they help:
TRC - 24
TRFC 127.5 (or it might say 3 in your BIOS)
A-sync - 8
Command rate (CR) - 2T

Hope this helps

Hauntsheep,
In BIOS: (My Gigabyte Bios gives a relative increase/decrease for all but CPU voltage)

A. Chipset/PCIE - +.15V
B. HT-LINK - +.15V
C. CPU HT-Link - +.15V
D. CPU V - 1.475V absolute (varies up to 1.65 under load; temp is 57C)
E. DDR2 - +.15V (1.97V absolute)

I don't know where to read A, B, C for absolute #. Sorry.
Robbie

Haunt, also don't forget that CTRL + F1 typically unlocks the "Advanced Options" menu in the BIOS.

Good luck
