Re: Can solder under IHS "go bad"? should I delid?

I just want to give an update on this. My friend helped me delid the CPU with his hot air workstation. Once it was delidded we added a bit more solder and used a soldering iron to make sure the solder was nicely spread on both the CPU dies and the IHS. ( the IHS was harder because it has much more thermal mass) Then we relidded it and I put it in my PC. It now runs much cooler, Even under full load it is cooler than its old idle temp. Old idle temp was around 60C, load would go above 90C, After delidding/fixing solder, the new temp under load is 48ish (idle in the low 30s now). I will update this comment with a link to the Youtube video once I have it.

tl;dr: Yes the solder under the IHS can go bad, and it is possible to fix by delidding.


Never before has such an obsolete CPU owed so much to so few.

Glad it worked!

Kinda makes me want to dig my old dual Socket A motherboard and Athlon MP chips out of the crawlspace and fire it up for old times' sake.
Nostalgia isn't what it used to be.

Be aware that they're no longer supported in Win7 due to a lack of SSE2 :wink:

In the same vein, I recently acquired a Pentium-166 with a 430HX chipset, along with onboard graphics and sound (not all that common until a few years later). I picked up a cheap Compactflash->IDE adapter, loaded Win98SE from a disc I still had, and then quickly lost interest. :roll:

This came about when my boss brought in every PC from his basement to have me destroy the hard drives. He was supposed to have a 386DX system in the mix (which was where my real interest lay), but apparently it had already been tossed.

Win2K would be a more accurate trip down memory lane for me anyway, since that's what it ran back in the day. I'd be more likely to load a 32-bit Linux distro on it if I was actually going to try booting it up today.

When I worked at the computer shop in the early '00s one day someone brought in a new-in-box 286 computer; it had never been opened and that thing was *cherry*, but he just wanted rid of it. Boss offered it to me and all these years later I regret a little that I declined.

I'm waiting for PhilsComputerLab (from YouTube) to come with a VIA mini PC that supports two expansion PCI cards so I can finally get a 386-486-Pentium retro PC.

I have one. Look for a PCChips M789CG motherboard. It's a VIA C3 motherboard with 2 PCI slots.

How are the volts? My brother's CPU was having a hard time keeping cool and I found the "Auto" setting for the Gigabyte board he has was volting the stock clocked CPU a solid 1.48v. Dropped it to 1.10v and the temps now don't even scratch 65c.

Ugh. I would've taken that in a second, even in the early 00's.

Stock on the auto setting it was about 1.22V @ 3.73GHz. Now I have it OC'd to 4.53 GHz at 1.31V with load line calibration enabled. Under load it goes up to about 1.35V.

Careful. PCChips has a well-deserved reputation for being garbage.

I thought about it, but couldn't see what I would do with a 286 that'd justify the space. :-?

I'm not worried about it. It's been rock solid for 13 years now. Lots of newer software won't run on it because the VIA C3 doesn't support SSE, but the software that does run on it will run forever without any problems.

Not to mention you need that brutish PSU. I only have the one PC Power and Cooling PSU that can boot a dual socket A board. All my other 40A @ 3.3V PSU's have died.

Mine was one of the later ones, and has a 4-pin Molex to supply additional juice to the CPUs from the +12 rail. But there were stories of the Molex overheating and melting (I never had that issue, fortunately).
