When you should purchase one thing at a low worth in a single location, and promote it at a better worth some other place, you’re engaged in what economists name “arbitrage”. We’re undecided if desoldering DDR5 chips from laptop computer SO-DIMMs to populate a customized PCB to create much-more-expensive desktop reminiscence counts as arbitrage, nevertheless it definitely counts as a hack. [VIK-on], who constructed the playing cards, claims he’s getting DDR5 efficiency at nearly DDR3 costs. Good!
Particularly, he’s put collectively a 32 GB UDIMM from donor chips from two 16 GB SO-DIMMs. The reminiscence chips themselves aren’t sufficient to make a stick of RAM, nevertheless: the half the place we want we had extra particulars was within the firmware. The firmware identifies this DIY DIMM as an ADATA AX5U6500C3232G-DCLARWH, particularly. [VIK-on] continues to be performing stability assessments, if these go effectively, we’re advised to count on a how-to information.
[VIK-on] is in Russia, so SO-DIMM charges might differ in your native market, however he claims walkaway prices of 17,015 ₽ — about $218 or €188, an astounding worth for DDR5 in these darkish days.
Some say soldering SIMMs appears extreme, however hardly unusual to Hackaday, and determined instances name for determined measures. It’s ether that or optimize software program, and who desires go to that effort?
