P4SD - case J7X

Re: P4SD - case J7X

I have a question, why does that area needed some heat, Ive always avoided applying such heat into that specific area given the fact that my common sense tells me that's the area most exposed to heat and high temps on the board while working....... ???

that's exactly the problem. solder connections of the socket get thermally stressed during operation.
if there's a prescott CPU on there, the temp always fluctuates between room temperature when it's off and the usual prescott temps of around 50-60°C when it's in use.
not to mention the mechanical stress from the heatsink..

both combined and the solder gets hairline cracks leading to that weird behavior like this board had (works only sometimes, freezes, etc. ..)

through-hole CPU sockets are far more robust against this, but were probably more expensive..

Re: P4SD - case J7X

^ Thanks.

UPDATE: I added the other DIMM, it has been working, mtest+ for the last 31mins, 2 complete passes, 0 errors. Still dont know if call it a success but one detail i like is the fact that I havent heard the CPU fan going to its max speed. I will update later on this day.

Thank you all, again, for the ideas and your time.

Re: P4SD - case J7X

UPDATE: As of right now, the board has been running mtest+ for 2 hours with no errors, with both DIMMs installed, I am about to leave and put it under mprime and check tomorrow.

Thanks again.

Re: P4SD - case J7X

UPDATE: Just arrived today -good morning- and the board has kept running mprime with successful results. I think is time to call it.

To everyone who helped me out, one more board fixed by this community;

THANKS.

Re: P4SD - case J7X

Good to hear it is working.

PS. Could you please not use so many in-line pics in future? It takes too long to load them all.

Re: P4SD - case J7X

Yeah, thanks!! Thats what ive been doing with the other boards I posted, and for sure i got otehr that just arrived which are going under same procedure, THANKS

and yeah i will try to imrpove my picture taking and posting, sorry about that.

Peace and thanks again for your time and replies. This particular board has had no return since released.
