I have a couple ripsaws so I will check on the numbers, any reason why serials matter? Does size matter at all?
The 1040 in the serial number denotes a particular make of the actual memory chips. In this case, 1040 means the chips are made by Powerchip Semiconductor. They happen to clock pretty well, but aren't made anymore so I'm looking for kits to combine with my current sets.
Size does matter in the case of these sticks. They were only made in 2Gb per stick, so they are most commonly found in sets of two. I would be interested in sets of three though, and they do exist as well.
Thanks for checking your stash. I figure people are going to start upgrading to DDR4 soon with the new Intel chips coming out so I'll see if anyone has these sticks and buy them up.
