Thinkpads Forum

I got a replacement motherboard off of ebay for my 760E 9546-U4B. I;m just now putting everything back together and I was wondering if I should apply fresh thermal compound to the CPU. The little metal heatsink fell off during disassembly and just wanted to see what everyone thought was necessary. I've got some arctic silver leftover from my tower, that should do the trick

Thanks

It wouldn't hurt to add it.

FWIW: AlphaKilo470 (thinkpads.com forum member) has several 760 mobo's that have the faster processor than most came with. He might be able to help you if you need another or are interested in a faster one...even though you just got the replacement off of eBay.

I have dealt with him on several occasions and HIGHLY recommend him.

Well, it always helps to use thermal solution though for the 120 and 133mhz chips though you'll still be fine as long as you have the grey thermal pad between the CPU chip and the metal plate that you screw on over the CPU core. However, if you want to try using a 150mhz chip or 166mhz chip in an older 760 that was not made for it, an additional thermal solution is a must and I'd recomend that it be applied in conjunction with use of the original grey thermal pad over the CPU core because without that, there won't be good contact between the CPU core and the metal thermal plate that screws on over it.

And thanks for the good word tfflivemb2, I do appreciate that. The 760 sorta became a hobby of mine after getting in touch with another forum member, therigwelder, who at the time had an endless pile of 760 junk. We were trading all the time and I even at one point at time, thanks to all the stuff I got from him, was able to build a few 760's from scraps. It's actually really fun because of the design on the 760, it's very customizable and easy to work with. I remember once having something I called the "Frankenpad" because it had a 760XD video card, 760E motherboard, 760EL soundcard and it was the product of merging two crapped out 760's with a brand new XGA screen.

It's just a 120, but I remember the computer getting pretty hot after a little use. I just wanted to make sure the grey heat pad would still be effective after losing contact with the CPU.

I had a 133 MHz chip, but a can't seem to find it right now.

Thanks,
Greg

i put a smidging of arctic silver on the cpu core only but the original mat excactly as it came out ,and run 200mghz all day no sweat
(with cpu mod)looking at the cpu heatsink design i just cannot comprehend how the cpus manage to stay so cool on these
and speedstep? heck these are the original speedstep cpus not the p111 hype intel rebranded.
runs 200 mghz on power and 120mghz on battery default no software needed. i beleive any tp 76xx is supported to 200mghz and beyond
where cpu allows.
also ditch the mwave audio and fit the ess souncard instead while your at it ,because the ess solo has superior support in 98 me,2k ,xp ,no drivers needed ,laptop runs cooler,faster,with virtually no detriment (if any to audio quality).

In theory, the 760's motherboard can run any clockspeed that's a multiple of 60 or 66. However, the fastest and slowest possible speeds are determined by the modules that IBM made for the 760s. The slowest CPU you'll get in a 760CD, C, L or LD is 90mhz, the fastest is 120, there is nothing in between.. In any of the other 760's, the slowest CPU you can get is 120mhz and the fastest is 166mhz with MMX, in between is 133mhz and 150mhz. You can find various CPU boards by parting out dead 760 units. XGA model 760Es will have 150mhz CPUs, SVGA 760Es will have 120 and 133mhz cpus as will the 760EDs. The 760EL will feature 120 or 133mhz CPUs, sometimes with L2 cache and sometimes without. The 760XL, XD, 765D and L all feature 166mhz Pentium MMX CPUs.
