Mach II temp ?

[Lee]

Hi everyone, I have a MachII which i thought had packed in because it would not cool below -20 on the LCD, i stopped using it for about 11 months and today i was packing it up and thought i would try it again, the temps on the LCD now where -49 and they stayed at that for the hour it was on. The only problem is it was set up on an old P4 2.4 on an IT7 max 2 motherboard that was not in a case. I could not test load temps because i have no operating system on this old PC. I checked temps in the bios and they where around 9 c (the head was not screwed on tight). Anyway, could there be any reason the temps seem to have normalised or is this likley to be only until i put it under load.

I don't want to put it back on my FX55 if it wont work properly.

Many thanks for any advice.

There is a big difference in thermal output between a 2.4 northwood and a FX55 (I am assuming clawhammer).

Overlcock the 2.4c to 3 gig and see what your temps are then (set your memory at 133 or 166 to enable an easy overclock).

Make sure the head is set properly too.

If temps are below zero (-20) in BIOS then there's a good chance (85%) that it's fine. To be 100% sure leave it in the BIOS overnight (or at least 4 hours)and check temps, if they are holding nicely then you know it works.

Okay the original R134 gassed mach2 was good for around 160w of heat - the clawhammer FX55 pumps out 104w at stock - but I would expect that you would easily obtain 3ghz (11x275) @ 1.6ish volts and work within the range of the mach2 you have there. you could probably run higher for short burst of benchmarking too.

But with a FX55 clawhammer CPU, you are right on the limit of a standard mach 2 so you have two options available to you:

Firslty, you could get your mach2 unit re-gassed to r404 (making it a mach2 GT 200w cooling) or r507 making it the best single stage cooler around for £175 from phil (EPUK will tune your unit to be ultra effficient too). Your FX55 will run happily at 3.25Ghz 24/7 then @ 1.7v

Or you could sell the FX55 and buy yourself a dual core 3800, venice 3800 or San Diego 4000 which all run cooler and probs overclock to be as fast (or faster) as what you have now under the cooling you have now (dual core 3800 is a good buy for the future).

Thanks ill try that. My system is very similar to yours except my FX55 is a clawhammer, but it is a good one i think, it runs at about 3250 on the mach II. I am going to send it to phill to test and regass. If i remember the mach could not hold temps, i think it must be a leak. Ill try your suggestion first though.

Cheers.

if there is a leak you need to pay repair as well, so all up its like £325..

I dont think there is a leak now because i just had it fitted to a p4 2.4 @3.1 and 1.7 volts and the Cpu temp was -21c for about 3 hours in bios.

thats good news...but arnt those chips pretty cold nywayz...Send it off then, and enjoy some better temps or wait for the mach 3!

Thanks for you help, its getting sent off next week for r507 gassing and repair.
