Clocking Advice/Tips Needed

Realist · 2 Dec 2007 at 13:13

Kept my settings as above but increased the FSB to 356 for 3.2Mhz and its stable with OCCT. Then increased to 367 for 3.3Mhz and thats stable.

So now Im going for 378 for 3.4Mhz and see if thats stable.

Realist · 2 Dec 2007 at 13:20

Crashed at 378 ;(

Realist · 2 Dec 2007 at 14:38

Running steady at 400X8 = 3.2Mhz.

If I go higher it crashes.

Ideas why?

CPU Voltage to 1.5V please.

Realist · 2 Dec 2007 at 21:51

Tried that, still crashes.

Currently running steady at 3200Mhz.

Then I reckon 1.45V is too much, all you're doing is heating stuff up.

Realist · 3 Dec 2007 at 14:33

So would reducing the CPU voltage help in this case?

WJA96 · 3 Dec 2007 at 15:09

Just in terms of heat production - if you don't need 1.45V when 1.4V would do, then why use it all? Also - have to seen the other thread about overclocking and cooling P5K's? The guy on that thread was using 1.57V to get his 3.6GHz clock stable :eek:

God thats way to high.

So far its stable at what ever the settings I have now (cant remember) so do you advise upping the FSB a notch at a time till I max out then dropping back and then upping the voltage?

Regards.

If you can find the thread, it had a link to another P5K overclocking thread that you might find useful, but otherwise, yes, upping the FSB 4 or 8 at a time seems a good idea.

think this is the thread(s) the op is referring to ie voltage and PK5 thread

The v-droop is horrendous on the PK5

Wish I purchased another type of board.

But so far Im running as follows:

Does it look ok?

Its a we bit unstable E.G: With OCCT it runs 15 mins into a 30 min test and OCCT crashes.

But PC runs fine.

Temps:

Idle: 38 Deg
Load: 55 Deg.

Yes, I'd say a straight 50% overclock looks just fine. Well done. I'm sure a modicum of fine tuning will see it stable very soon.

Ummm dropped it back to 3200 due to running Prime95 and it crashes and burned.

what core voltage were you at for 3,6?

voltage now at 3.2?

and your temps presently idle and under load (core temp)?

Realist · 3 Dec 2007 at 21:30

Temps are 39 Deg or less idle and 50 -55 under load.

At 3600 the core voltage was 1.5 and at 3200 its 1.35ish.

CyZMyAssBaby · 3 Dec 2007 at 21:33

It may better to settle for the 3.2 over clock as you are under air. which is very decent over clock by the way. You would require voltages above 1.5 to achieve stability for 3.6

just leave prime to run at 3.2 overnight to confirm system stability

Realist · 3 Dec 2007 at 21:48

True.

Whats the best way to setup prime?

Before running prime you will need to open core temp to monitor temps whilst running prime.

Before running prime you will need to open and:

under advanced tick off "Round of Checking"
select small FFTS
Select CPU test not blend (you can run blend test later if you pass 8hrs stable on CPU torture test)
And run

Ok thanks.

Started Prime and I see something happening and the processor are running 100%. How long does this go on for?
