Solved Swapping parts between 2 different tablets - Good/Bad idea?

Motion computing Le 1700
September 11, 2013 at 17:13:09
Specs: Windows 7 Pro, core-2 duo/ 4GB (2x2Gb matched pair)
I think I may have a cooling problem in my Motion Computing Tablet LE1700. I have some used Motion LE1600 & LE1700 machines. Can I use the fan and/or heat sink from the LE1600 to put in the LE1700? Got some new Kingston memory from NewEgg (matched pair, with dual-channel memory support). Seemed to work ok for a while, then started to get BSODs pointing to possible memory problems; I did a MEMTEST and it seemed to also point to probable memory problems. Just switched back to some memory I got from eBury: the sticks aren't matched, may be a little slower, but so far no BSOD...today. Could I have gotten some bad memory?

"I think I may have a cooling problem in my Motion Computing Tablet LE1700"

What do you mean, you think you have a cooling problem? Either you do or you don't. And the only way to know for sure is by monitoring the temperature. Which CPU do you have & what are the temps at idle & under load? From what I could find, you probably have a C2D L7400, if that's correct, the max temp is 100C.

"Can I use the fan and/or heat sink from the LE1600 to put in the LE1700?"

It's difficult to say without seeing them.

"Got some new Kingston memory from NewEgg"

The C2D L7400 runs at 667MHz FSB so the correct RAM would be DDR2-667. Is that what you got?

"I did a MEMTEST and it seemed to also point to probable memory problems"

As I said with the cooling, either you have a problem or you don't. If memtest86 is showing errors, the RAM is most likely defective. Did you test each stick individually & then both together? Did you try switching slots?

"Could I have gotten some bad memory?"

It's possible. You need to confirm it's bad by running memtest86. If you get consistent errors, contact Kingston & have the RAM replaced under the lifetime warranty.

Wow! Thanks for the feedback. What program do I use to determine temperatures?

The BSODs I was getting:

IRQL_NOT_LESS_OR_EQUAL...
PFN_LIST_CORRUPT...
MEMORY_MANAGEMENT...
BAD_POOL_HEADER...
PAGE_FAULT_IN_NONPAGED_AREA...
BAD_PAGE_CALLER.

Did a Google search on these and what I gathered from all that seemed relevant to my machine was a problem with memory. The memtest86 also seemed to point in that direction. Contacted Kingston for replacement. Waiting to hear back from them.

Yup! That's the exact match: KVR667D2S5K2/4G matched pair with dual-channel memory support.

"Did you test each stick individually & then both together? Did you try switching slots?"

No (got my RMA from Kingston) but tried the memory again to confirm it was bad: immediately Blue-Screened on first attempt to boot. Guess I got my answer for that one. Thanks!

Got the replacement RAM from Kingston & works great. still seems to hang up at times when clicking on certain web pages though.
