P4 2.6 OC what is Safe???

**SoSl0w** · December 31st, 2003, 02:36 AM

I have a
P4 2.6 w/ 800 FSB (stock Fan)
P4P800 deluxe ASUS MoBo

My question is using the ASUS Bios what percentage is safe on a stock fan? 5%? 10%? 20%? 30%? Is it better to use the ASUS preset percentages or would going in manually and adjusting the setting work better. I have the Intel fan that came with the CPU and I was concerned with the temps that would result from pushing it up. Any help would be appreciated.

I've heard the "intelligent" overclocks arent necesarily all that smart. I have that motherboard but I've never really messed around overclocking with it. Prolly want to simply move the fsb up slowly and if it becomes unstable try upping the voltages a little. Theres definately some other members who can help you more with it

I've heard of 2.4s being overclocked stable to 3.0 on stock cooling and still stable, so id say 20% would definately be feasilbe..

You cant hurt it, it will throttle itself or not post if you are too far out of spec, the retail cooler works quite well by the way, it speeds itself up as the temps rise...

Yeah, with a P4 the worst that can happen is it will slow the chip down. You probably could kill it by overvolting it, IDK. So long as you're not silly it won't come to any harm, and even then.
Fans with temp sensors built in should be left alone. Those boards can go screwy sometimes, and its best just to disable them to be safe.

TTT

Has anyone used a MoBo's percentage settings all while using their stock fan?

dont use the percentages... do it manually!

I heard the 2.6 P4 was an overpriced and over-rated processor. Is that why you are trying to overclock it? Trying to get a little more value out of your machine?

Set your overclocks manually
percentages can be dangerous!
imagine for a p4 3Ghz - 20% is 600Mhz! without insane cooling your machine is not even going to boot.

You need to know the basics of overclocking before u start meddling with the BIOS settings.
when the FSB goes up, you have to see if your memory can handle the higher FSB, else you would have to use a divider like 5:4 or 3:2. Don't forget to lock your AGP / PCI bus as well.
your Vcore may also have to be raised slightly to maintain stability.

2.4 at 3g
2.6 at 3.44g
with little more then stock cooling (Vantech Aeroflow)
Nothing special, no jumping thru hoops, no expensive parts...

2.6 C costs less than a 2.4C...

Always 20% on stock from my experients.

Throw a Vantec Aeroflow or a Swiftech HSF on that baby!

I have since pushed the CPU upto the ASUS setting of 20%. I ran a few PCMark2002 and PCMark04 tests then backed it down again. I never saw extreme heats while running either test. I backed it back down b/c I did not like the way the ASUS board dropped my DDR setting from DDR400 down to DDR266. This made my memory score low on the PCMark2002. I am running at the ASUS setting of 5% now, the board leaves the memory at 400 and the CPU is running at 2.7**. I guess I will have to read more into OCing so that I can do it manually like everyone suggests. Next question: What is the best non-water cooling CPU cooler? I have had 2 suggestions, any more?

i got a 2.53 running at 2.84 w/ stock fan at 39C.

I took it to 3 ghz but it din book so im keeping it at this until i get a better fan/heatsink
