Celeron M ULV

[nocture]

Hi there,
I'm searching to buy Celeron M ULV 353, 373 or other cpu witch can do fanless operation. So I don't know where to find some of those and for what price. If anybody knows where could I buy such processor and for what price I'll be very thankful.

The Celeron M ULV's were never very popular in the first place, Pentium M ULV's were generally used. I would try to find Pentium ULV's, but even those will be rare. Also look for the Core Duo Low Voltages or Core Duo Ultra Low Voltage.

Another thought is you can take an already low power CPU (maybe the 35W Athlon 64's or something) and undervolt/underclock them. All the Intel ULV CPU's are run at lower clocks. I'd imagine you could run a Turion 64 underlocked, undervolted, and fanless.

It's actually for stable embedded system and this with underclocking seem to be not the right decision. I don't trust at Athlon64 underclocked to work fanless.

You might look at a normal 90nm Pentium-M chip, virtually all of them can undervolt to lower than ULV levels.

I have a P-M 730. At 1.6GHz its fully stable at 0.958v, power consumption of about 6W with CPU Burn. When idle, it can go down to 800MHz/0.700v.

Then for embedded you're going to want something like AMD's Geode processors.

I realy don't like the motherboards for Geode processors. Another solution is Single board computer, but they seem to be more expensive. Accord99 can you give an example for a motherboard s 479 which can do stable undrevoltage/undreclocking?

Thanks

Hmm... From this review, it seems that the AOpen i915GMm-HFS is definitely capable of undervolting.

The reviewer ran a P-M 755 at 1.1v stably.

For underclocking, you might need to use a software package, like RMClock which can force the CPU to never clock up from 800Mhz.

It's not bad idea, but Intel Pentium M (Dothan) underclocked to 600Mghz I'm not shure it'll be enough. I realy like Dothan and I'll see what can I do. Thanks a lot.
