Overclocking my 3700+

Six6siX · 15 Jun 2006 at 13:05

Thought I'd give it a go - just to see how I get on, heres what I have so far...but I dont know whether I'm going about it the right way...lol so any advice appreciated.

Spec:
CPU: Athlon64 3700+ San Deigo
Mobo: Asus A8N-E (nForce4 Ultra)
RAM: OcUK Value 2GB
GPU: Radeon X850XT

Current settings:
Running the RAM at 2.5-3-3-8

I've put the HTT down to 4x, dropped the memory to 333 (is that the right thing to do???) and have been increasing the FSB and currently at 250, giving me 2750Mhz...currently at 1.45v

About to run some benchmarks, but am I doing the right things?!

If it's stable that great, mine would only go to 2500 mhz! But yes the settings you have set are correct.

Update, running prime95, failed small FFT test after 2.5 hours

Does that mean more voltage is needed?

Try a bit more voltage..

i put 1.6 volts through mine to get 2.8 stable

EDIT : Thats with a scythe ninja cooling it though

aye sounds about right

Same divider for me and running 250 x 11 for 2.75ghz - mine is at stock volts for that. Ram on 2-3-2-5 with the 333mhz divider.

Ok, thanks for the replies, I'll give the voltage a go.

Cooling is a Big Typhoon btw, forgot to mention that. Although - my room is pretty warm so temps are a bit high.

booyaka · 16 Jun 2006 at 14:17

keep an eye on the temps mind you.

Mine idles about 31 and max's about 43 at normal room temps.

Dont just fire it up to 1.6v, when you could probably get away with 1.5v. The less volts needed, the better.

Six6siX · 16 Jun 2006 at 14:39

Well idle at about 39 @ stock due to the weather...

I tried more voltage, but for some reason, my system kept locking at boot over 1.475v. It'd stop just before the windows loading screen.

I tried playing about with HTT 3x, but that didnt help. Managed to get memory to 2.5-3-3-5...but I dont think that'd make any difference.

Back at stock now, any ideas?

What board are you using?

Asus A8N-E, i said in the OP

Been playing around a bit more, and it boots up at 250x11 HTT @ 4x without a problem at 1.475v. I will prime test at that voltage and see how it goes, increasing if necessary. What's considered a reasonable length of time to run the test for without errors to assume a stable clock?

Also, I tried dropping the HTT to 3x just playing about to see if I could go above 250, but then it kept stopped before the windows logo again.

Some boards can be funny when reducing the HT, eg mine doesnt like 2/2.5 for some reason. You could always try another bios.

To say that system is stable enough i would say you need to be able to run for 12h with no errors. If you want make sure your system is rock solid then for 24h with no errors

.

Hope it helps.

Cheers

Everyone has their own idea of what stability is IMO,

My CPU @ 2.8 Doesnt Pass Prime 95...

But it can play counter strike source and battlefield 2 for hours and hours non stop without failure / crashing
