Help me overclocker my new AMD Phenom II X3 Tri Core

iMacMart · 21 Feb 2009 at 00:41

Hi guys

I have changed the multiplier to 17 (I think) clocked to 3.4 at the moment with stock everything!

Idle temp is 24 according to Coretemp although its only showing CPU#0?

Whats the next move from here to get it up to 3.8 say?

No one

I want to see what this can do but haven't overclocked AMD for years!

just up the multipler untill it fails/doesn't post then go down 1 multi and boot in to windows, run prime95 for 2 or 8 hours then if that pass and if u want to overclock more just bump up the voltage alittle.

Phenoms only have 1 temp sensor..

what cooler do u have?

Found a good guide on toms hardware

Will see how it goes

Cooler = Thermalright 120 Extreme...

quality cooler, just keep an eye on the temps as you go.

idle 24 at the moment, what's the best stress test? orthos?

yes or prime95

just be careful if u bump up the volts

at stock volts my 940 idles at 25c, 34c underload but with a small bump up on the volts +25.0mv the temps go to idles at 30c, 60c underload with running prime95 only for 15min :confused:

.

i know yours a 720 but basicly the same just as 1 core less.

Whats the max volts for these? 1.55?

if you have extremely good water cooling setup then you might get away with volts as high as 1.6 but that would be living close to the edge i think
most will do 1.5v -1.55v but you will have to have very good cooling.

1.425 thats not that high is it?

Im running 1.5 on air and even running orthos mine doesnt go over 45 degrees...

Whats your idle temp mate?

My RMA'd ram will be here tomorrow so I'll be over clocking the CPU some more

nope, but thats what AMD recommends...

73c is a long way off for me at the moment, only hitting 30/35 at loads so fingers crossed it has lots more to give

Idle is around 38, it doesnt go up much even under full load.... But idle isnt that low...

iMacMart · 24 Feb 2009 at 22:29

What's the most reliable CPU temp monitoring software? Coretemp?

Coretemp reads my cpu @ 25 idle

Speedfan read it @ 34 idle?

gareth170 · 24 Feb 2009 at 23:08

Speedfan read sound more like it..

try EVEREST

Hi guys

Can get to 3.5ghz with just multiplier overclock then it won't boot?

Set the settings below, but should I be upping the north bridge to assist in overclocking? If so what volts do I start with on my board?

Temps idle are 25 and 30 load so temp isn't an issue at the moment

Any advice would be great

I really want to see what this chip is capable of but stability is key

Disable Cool ‘n’ Quiet

Disable C1E

Disable Spread Spectrum

Disable Smart CPU Fan Control

Manually set Memory Timings

Windows Power Option and High Performance
