Use an P4 Intel M SL725 on a desktop

Yes Barbarossa,
I read your comment about BIOS, but this is the part that depends on the specific BIOS options and motherboard. The Asus P4S533-MX with Award BIOS offers some options that are likely to control core voltage and CPU speed.

Thanks again for your advises. The SL725 I expected for a month bounced back at customs because the sender had only written his return adress, without his full name. He gave me a refund and I purchased another 2.8Ghz CPU (NOT M) with Hyperthreading, and twice the cache and bus frequency. This should definitely bring my main computer up to new levels...but...

The extra cost of overclockable motherboards and super efficient (often too noisy) cooling fans required to become a modest overclocker made me think twice. I do have standard INTEL cooling fans, not recommended over 2.8 GHz because the heatsink is not omnidirectional.

I will stick to regular motherboards that are well documented and predictible. I admire the skills and knowledge of this forum members, but... i'm not a gamer and my children needs are limited for now. My pride is to have upgraded our family network from two PIII 866 to three P4 2.53-2.8 GHz from used and recycled parts, all for the equivalent price of a single new one. Beleive me, the result in terms is performance is VERY noticeable.

Thanks again for you kindness and curiosity. This forum is very impressive.

Well that's good news - Hooray for customs- too bad they can't keep 'Everybody Loves Raymond' reruns out of Canada too.

Keep in touch

Ahhhhhhhh. Customs..... I get alot of stuff from the US and I never know when they are gonna be jerks. In fact, I have a box of stuff coming from a US contact right now that I pray makes it through without me getting a beating.

That's an admirable feat, and nothing that tweakers would sneer at.

Most computer users barely know how to turn them on.

You've played with the guts and came out the other end with an end product that fits your needs.

Congrats!!!!

Yes it does work on an Intel D865GBF and an Intel D865PERC mother board, but only runs at 1.6 GHz speed. I know, not because I tried it but because I used it that way for about a week. I had 3 CPUs and I got two of them mixed up. The day I went into bios, I realized it was at 1.6 and then found my mistake. I then had it laying around and just out of curiosity I put it in my D865PERC (same as the GBF, but without the onboard display) and still registered 1.6.

You need to use a small hammer to make all the pins fit. Nope... just kidding... it slips right in... nothing special in the physical configuration.

The only problem with specs is matching the CORE VOLTAGE, Intel is telling me 1.3 volt and CPU World Website specifies this M type P4 can work with a core voltage between 1.2 to 1.525V. I wish intel were more specific ! There is no confirmation ont their website whatsoever about core voltage range for that processor.

As far as I know, a desktop motherboard will detect the appropriate core voltage up to 1.525V. In such case, I am understanding it would run at 79.38C wich is within its thermal specification.

QUESTIONS: WOULD IT WORK ? IS IT SAFE TO TRY ? WOULD IT REQUIRE MORE THAN A STANDARD INTEL CPU FAN MADE FOR 3GHz ?

Thank you (see specs below)

Here are the specs I found on CPU World Website:

V core (V) 1.475 - 1.525
Min/Max operating temperature (°C) 5 - 75
Min/Max power dissipation (W) 76.58 (1.475V) 77.98 (1.5V) 34.06 (Stop Grant mode) / 79.38 (1.525V)

Processor frequency is reduced to 1.6 GHz in battery-optimized mode (1.2V)
