Trouble overclocking

Blade1 · 28 Nov 2009 at 07:14

Hi all, first build with a Asus motherboard so bit rusty on this (always used Abit)

System:
Amd Phenom IIX4 Quad Core 955 Black
Asus M4A79XTD Evo
G Skill Ripjaw 4GB 2X2 DDR3 1600MHZ 9.9.9.24
Coolmaster scout case
OCZ Modstream pro 600w psu
Geforce 8800GT Graphics card
Zalman cpu cooler 35 idle
Samsung HD103SJ 1000GB H/Drive

Having a bit of trouble overclocking, all i can only manage stable is 3500 GHZ
v/core at 1.45v
9.9.9.24 1600 1T 1.66v timing
VDDA 2.7v
219x16 manual setting overclock

As i said first build with Asus, what do you think i need to up or set?
I have flashed the latest bios and tuned of cool and quiet.
Any thoughts on this appreciated.

18x multi, 12x NB, 2.2GHZ HTT, 1.55V on CPU, 1.35V on CPU NB (Forget finding minimum voltages at the moment)

good move over to Asus

(i did the same, no regrets!)

try keeping the FSB at 200 and increasing the multi only, you should be able to do that on your black edition right?

Sorry Martini1991...12x NB whats this in the bios? 2.2GHZ HTT is this HT Link speed? 1.55V on cpu is this the voltage on the cpu, this is on auto at the mo, but when i press the + button in the bios ,it takes a while before i get to 1.55v, wanted to check fist before i go ahead.
Sorry got to get my head around these bios settings and names.

CPU northbridge, HTT is HT link speed.

Thanks, let you know how it goes.

Nope, wouldent even boot at them settings....i can get it to at 200x18 and everything else at auto, but fails prime and BSOD.

Don't leave at auto, and you have to up volts.
My board's pretty rubbish for overclocking, and I managed to get my 940 24/7 stable at
3.7GHZ (18.5 x 200), 2.8GHZ NB (x14 multiplier) 1.55V CPUNB (Overkill but my temps were under 60), 2.6GHZ HTT (2600MHZ hyper transport link).
I also upped the Northbridge voltage on the motherboard, but CPU NB is part of the CPU.

Ok, got it prime stable at 3600GHZ, mem at 1600 im happy with that...thanks for your help.
