1.7-1.75v is the max recommended voltage. Those of us that have been at it for a while, and have sub-ambient temps may go for more from time to time, but not for continued operation. So, stay below 1.7v for good air cooling, and 1.75v for good water cooling.

Hey all, I have a P4 530, and don't laugh here, the highest I have got it is 3.32ghz. Its only my second attempt at overclocking, and I've got one question, I've done this on two machines, and I can get an increase in say, 25FSB, then if I go much higher, I get nothing on the screen when it boots up, everything is on and going, and I have to reset the BIOS to get any visuals again. I'm sure this is a case of upping something else in sync with the FSB or something, but I dont know what, so could someone tell me?

Matt :-D

Make sure you locked the PCI/AGP frequencies to 66/33 Mhz. That option should be on your BIOS. Good luck OCing that system

Cheers for that, I'll try it, before I do, I'm just making sure here, I've shelled out serious cash on this system, so I want to get this right, its a 925XE motherboard, and my graphics card is PCI-Express, does that make any difference to the PCI/AGP frequency setting I should choose? Full specs if its any help are:

MSI 925X Neo-Platinum Mobo
Intel Pentium 4 530 LGA 775 CPU
512MB of DDR2 533 Crucial (Value S*** :-(, and not 1 GB yet)
Asus X600XT PCI-E
Creative Audigy 2 ZS Platinum Pro
SATA Hard-drives.


Also, will a serious overclock damage my PCI soundcard? I'd heard somewhere big overclocks could cause your PCI cards to run too fast. This could well be crap, but I'd rather check! Got the Gigaworks speakers, and if anyone on here has got them, they'll know why I'm anxious about the sound lol.

Cheers for that quick reply, and sorry for asking, how do I rep you?

Matt (feeling like a total n00b ;-))

EDIT - Ok, just actually looked at the page, and kinda figured clicking the plus sign next to the whopping great rep logo might just help, apologies lol :$)

My mums P4 2.8Ghz Northwood gets to 65C not even overclocked. A guy I know overclocked his P4 530 3.0Ghz to 3.8Ghz and his heat was idle 55C and at full load the heat hit 75C. He's been using his CPU at those temps since something like august. It's still going strong. Also, my mums computer got up to 3.2Ghz then started to have blue screens and restarts. The heat is not the issue becuase i had the case of and it was on top of the desk with the aircon blowing right onto. It's not the ram that's the problem becuase i turned the RAM:CPU multiplier down to x1.66 and the RAM was underclocked a few mhz. Do you think it's the voltage becuase my mums motherboard doesn't have voltage control.

It's prolly the vcore, try upping it a bit. On Northwoods you can go up to 1.7v safely but try to keep it as low as possible.

my 530 3.0 ghz is now at 3.6 and it looks like it wants more. And this is done without messing vcore nor mem voltage. 1.4 and 1.8 respectively. Looks like I can still go further. Wish me luck guys!

now I got it at cpu 250 mhz, 1000 mhz FSB with x15 becomes now 3.7 Ghz. So far it boots up well, no problem with heat (water cooled). Should I stay, or push for more?

Just to clear some things up, from the beginning of the thread (I hate misinformation )...the increase in memory bandwidth, between single and dual channel, is around 60-70% (increase, in favor of dual channel). If you're using an 800 mhz FSB CPU and DDR400 (with both running 1:1), then going to dual channel will further increase overall system performance by 3-5%, due to PAT activation.
