0x0009 - RAM Upgrade, the hard way 

Solder braid should not leave strands. If you leave strands behind, you're solder heat is not high enough and you're basically sinking the heat and the solder cools before it's done. There's an art to it all to make it clean. The sucker is more for bulk solder and thru hole in reality.

Make sure to grab some flux for those delicated parts. It helps a lot.

Lord, fix that description it just makes you look like you skipped primary school. It's *to its maximum*.

I've never seen somebody doing component level board repair professionally use a sucker, but anyways: footguns sometimes make for great content :)

You are right, but the sheer force of this sucker is just way too much for solder pads. Remember: Soldapult was made for through-hole components when it was invented. In theese times you could have as much force as you wanted to blast off the solder from the pads. 0806 pads are way more fragile and you'll do yourself a big favor if you'd choose solder braid for those.

don't forget the blue table

FRIENDLY JAPANESE BUSINESSMAN Excuse me? I am fully aware that he doesn't do actual drugs and yes I DO get his humour.

Druaga doppelganger

stop following me sir

Sign me up for a retro tech channel with casual drugs!

The reason was that Window 98 needs 24MB of RAM. But in the end I decided to leave it as a Win 95 machine since it has a bit less overhead.

i was about to comment the same, he sounds the same, acts the same, the format is similar, druaga had a clone while he was high?

That's the same thing I was thinking haha!

even if he did he still would need to redo the gold plating and the globs of solder left on the pads then he tries to insert lol

+Kev711 2001 my technique is to solder a wire to the track and heat it until it melts then slowly let the solder cool a little bit then i cause a fracture of cold welding right at solidification temperature (you probably desoldered something like that before unintentionally).

+Kev711 2001 gold doesn't stick as much to the solder then the solder is almost at melting point.

I've used one of those before at work, they are much better for this sort of task. That's why I went off cam and used my heat gun. But I don't have a hot air "pencil" station yet. It's on my list of items to get at some point, just not at the top. I don't want a cheap garbage one so I'm waiting to get a better one with proper flow and temperature controls. I can make up for lacking it with soldering iron skill for now.

It is good to have a spool of solder wick (braid) handy for cleaning bridges, blobs and generally messy solder joints. Also it would have helped to lift the chips. In a pinch, you can substitute with the braided screen/ground cable on RF coaxial wires. A dab of flux and away goes that extra solder.

the solution to the problem here is to use a razorblade to cut the solder, i fucked up my gpu like this and the scraping method works wonders.

Cheapo phones that like 5 people own "HEY GUYS COME GET THIS 'DEAL' ON THIS RANDO FUCKIN PHONE"

BLU is the fucking master of this, they'll just release random OEM phones that are exactly like another without any fucking documentation on them

Acer bought Gateway in 2007, so it might be still proprietary to Gateway, and they perhaps used the same modules? I'm open to being corrected.

@@fabian999ification This is a 90's laptop, made over 10 years prior to that even, I highly doubt it's related ^^

@@Dxceor2486 Ah I see, that makes sense. Sorry for the late reply. Idk what I was on about, your reply makes a lot more sense lol

in goolden days widoe would have to be cut in 3 minute segments. and have cats. If you think about later it would be 5 minutes.

that whole module has seen worse than hell lol

Personally id use a heatgun or an oven

I would assume the actual max is probably 32MB, with two 16MB sticks. The 24MB limitation is because the on board module is 8MB, and yes at the time 16MB would have been the largest (commonly available anyway) stick. Caveat - sometimes you can use larger sticks down the road, but at the time of manufacture that configuration is untested, so it's a bit of a crapshoot. Provided the BIOS isn't artificially limiting anything, you could use up to whatever the chipset's max would be, which would be the absolute upper limit. If you wanted to go even dumber, since this was before integrated NB and what not, you could conceivably switch out the northbridge / memory controller and maybe push further, but even that is limited by what cpu's said NB supports, and bios support to recognize and operate the chipset.

Thats what i was thinking while i was watching this

* laptop SIMMs. (I don't think SOSIMM was a term... maybe mini-SIMM?) DIMMs only became a thing with mid-generation and later Pentiums. If you're searching for DIMMs / SODIMMs in that size range or for 486 / early Pentium laptops (or desktops), you're most likely going to be disappointed, either from a lack of results, or something incompatible turning up in the mail. At best, you're going to get all the misspelled and incorrectly listed dregs (with the price either being actually pleasingly low, as no-one else will have bid, or stupidly inflated because the seller overestimated the value but there are literally no other options) when if you used the right terms you'd have dozens to pick from and could almost guarantee getting it at a fair price. 72-pin is 32-bit tech, thus SIMM. And I have a feeling that pin count only actually applies to desktop modules anyway, or laptops that take the easy route and just use desktop memory parts. For a subnotebook like this, you definitely need specific reduced-outline (and likely different pinout) laptop parts. And yeah, if you can afford to experiment, in a case like this it might be worth trying a 32mb module and seeing if you can get up to 40mb. I know that's a config that at least a few machines officially supported (it is, after all, a simple doubling of the maximum situation described in the manual - 4mb onboard and 16mb upgrade installed), and 64mb total seems to be a common claim for 486 desktop boards in the DX2 / DX4 era, though some are allegedly capable of 128mb either officially or otherwise. Which, as they tended to have four sockets, would match with a laptop offering two (the virtual one onboard, and the actual upgrade slot) and technically capable of either 32 or 64mb total, should you also go Beyond The Impossible to upgrade the onboard memory. The caveat in those cases is that it might actually end up harming performance - there's not much software you can run on a 486 that can make meaningful use of more than maybe 32mb, and once you reach 64mb, never mind exceeding it, the common 486 chipsets have difficultly cacheing the full amount. Which means you could well end up with large parts of in-use memory being uncached, and the computer will actually seem to run slower with the larger memory count than it did with just 16, or certainly something in the 24 to 48mb range. Maybe if you had a really good memory manager overlay program it could specifically allocate hard drive RAMcache to those areas (as it doesn't really benefit from CPU or L2 motherboard cache the same way programs running from RAM do themselves) and limit program loading to the cached area, which would give you a considerable loading speed boost for any data that has to be repeated loaded in (and if that's a full 32mb, well... a great deal of 486-era software is much smaller than that. You could probably fit most of DOS, Windows 3.1 and 1993-era Office into that, and certainly the OS plus Works wouldn't even touch the sides). Even if you're running an SD card or other flash device, and so not worrying too much about the media speed or access times, the IDE interface will be, at best, DMA-16, and in some cases either a slower DMA or even rotten old PIO mode, so having the data already sitting in memory would be a distinct advantage.

coz youtu be would rather u watch loganpaul

xX_SpeedyScout_Xx be patient, it will come up. Also, some interyoutubers work and project seems to be a great idea to build interest among inter related subject Chanels. Like techmoan and the 8 bit guy to sometimes collaborate together...

He didn't know that, and probably saw in the manual: ''use only our very expensive special RAM!''. Many people at the time (and still to this day) were swindled by that, so he tried this extreme experiment. Yes most STI-DIMMs of that era will work in most machines. You don't need to search for RAM for your specific machine - if it fits in the slot then it'll probably work.

sl9sl9 Some brands of the era had tiny differences to detect wrong brand RAM modules. Large 3rd party RAM brands like Kingston offered separate modules for each such brand.

That's as maybe, but... yknow... Google. It's so much easier to learn lots of stuff about technical subjects so quickly now. Five minutes on a forum would probably have cleared up the question, rather than just blindly typing the same search terms you'd use for a modern laptop into eBay and then being surprised when you find relatively little suitable for a 20-year-old machine.
