A forewarning: I'm dealing with outdated RAM types here (PC133 SDRAM, not DDR-anything), and am not interested in buying a whole new computer just because of this minor issue. This setup works fine as it is, I just put a new graphics card in it in fact, but there are some very small issues with lag in a couple places and I hope maxing out the RAM will solve or greatly alleviate the problem.
So I want to upgrade my RAM. Currently, this computer has one stick of 256MB PC133 SDRAM, and the chipset specs state that it can handle a total of 512MBs. I'm looking for either another stick of 256MB RAM to add to what I've got, or a 512MB stick to replace the one that's in there entirely (unless of course the spec sheet on Intel's website for the i810e is wrong and I can actually have 768MBs of RAM in this thing - still, a 256MB stick is probably cheaper)?
A couple years ago, however, I'd tried putting a stick of 128MB SDRAM in this computer and couldn't (or more hopefully, just thought I couldn't, which would make me feel like an idiot but at least more comfortable with doing this now) because the stick was too physically large to fit (which is where the 'or so I thought' part comes in; maybe I just didn't realize how to put the darn thing in, but I'm fairly sure it actually was larger than the clamps allowed for)?
Anyway, with that in mind, I want to know a few things:
*Are all desktop SDRAM sticks 168-pin?
*Are said SDRAM sticks physically the same size as DDR266? (I ask because I had ordered a stick of 512MB DDR266 to put in here only to find out this doesn't take DDR memory; the DDR stick and what I've got are the same physical size, though)
*Does Non-ECC or ECC matter in terms of size, or performance, etc.? I suppose this question also applies for DDR variants, whenever I do finally have a setup that needs DDR.
Finally, and perhaps most importantly in terms of the order itself, has anyone ever used memorystock.com? I found an entry for the computer make I have, and it lists having compatible memory modules available, but I've never ordered from them before.
