Ok, so im a noob to O/C and wanted some general advice on my first attempt.

System is:

Pentium D processor 3.2ghz (presler core)
Asrock Dual Core VSTA motherboard (not great i know)
2 Gig DDRII ram at 533 (kingston budget)
256/512mb 7300le nvidia grpahics card
500w optronix silent PSU

What i would like to know is,

Do i start by upping the MHZ frequency in the bios by 2 - 5 mhz at a time looking for stability on the system?

I have read that this CPU will clock happily up to 3.8 on standard power usage. And for anything over 4 gig it needs upping to around 1.4 to 1.45 v (core) but can be a little unstable over 4gig.

I take it all the options i need are in the bios setup.

im not a PC noob, built plenty and fixed plenty in the last few years, but never O/C'd before.

i cant help thinking how much better the pc will be with a 3.8 dual core chip, over the stock 3.2ghz.

Thanks in advance for any advice

Oh should have added:

CPU idle temp is 41 degrees

CPU 100% load is 48 degrees

using this heatsink and fan

http://www.overclockers.co.uk/showp...

are these temps ok to O/C on?

CPU FSB = 250Mhz (5Mhz increment from 200Mhz)
CPU multiplier = 16x
CPU:RAM = 1:1 ratio or 200Mhz RAM = 200Mhz FSB in the BIOS
CPU vcore = 1.3v (+0.025v increment for further stability)
PCI-E/AGP/PCI = 100/66/33Mhz

As for temperature during full load after overclock, if the CPU does not throttle under heavy load, then there is nothing to worry about...

Many thanks for the advice!

If i do anything wrong, i take it a cmos reset will get me back to normal to try again?

Ok, so far i have gone upto 3.36ghz

multiplyer x16

with a ram / cpu ration of 8:6

CPU fsb 210 (5% overclock)

idle temp is 42 load temp is 47

I dont actually understand how to get a ram / cpu ration of 1:1 but i'll keep messing around! lol

Neal

now upto 3522.1 mhz

Cpu fsb 220 (10% overclocked)

multiplyer of 16

ram / cpu ration of 8:6 still.... cant work out how to change that.

Idle temp at 43 / 44 degrees C
load temp in full stress test was 52 degrees C (using everest stress test)

Throttling, never went over 0% during stress test.

Im going to leave it at that for now.

Im happy with dual core 3.5 gig really, i dont do much on the pc other than play the odd game and do some excell work at home lol

Maybe you should search an option in the BIOS like RAM speed = DDR2-400 DDR2-533 and DDR2-667 and select DDR2-400 mode... If you can't find any of those option in the BIOS, then you can simply relax your RAM timing to 5-5-5-12 and increase the dimm voltage slightly like +0.1v to push the RAM further...

Cheers TMP man, will try your advice as soon as i get home!

I tried overclocking my works pc this morning, but with an increase of 10mhz on a P4 2.4 ghz chip, i lost all graphic output and had to reset the cmos! lol my boss wasnt impressed
