The memory I got that has this IC is from a 32GB (2x16GB) DDR4-3000 CL16 kit of GeIL Evo Potenza model #GAPB432GB3000C16ADC being advertised as specifically designed for AMD Ryzen. Unfortunately, Thaiphoon doesn't have a full part number for the IC on this, with a read on either slot giving part number K4AAG085W?-BCPB which I couldn't find any info for whatsoever. My assumption was initially Samsung D-Die, but the info I can find for it online points to a part number with K4A4G085WD, and of course if it were E or S-die the part number would end with those letters.
Not only that, but this stuff has a 16Gb die density, not 4Gb, meaning each 16GB module is actually single-rank which I'd never seen on Samsung DRAM. The manufacturing date for it is very recent, November 4-8/week 45 of this year which is less than 1 month ago. According to Newegg, this kit using that RAM was first available on 10/07/19 so there's no reviews or info on the web about it and based on previous data points I surmised it would be Micron B-Die but it ended up being some type of Samsung IC after installing and checking BIOS and with the latest version of Thaiphoon Burner.
I'd been looking to upgrade to 32GB on the cheap while having a chance at decent performance via tuning and noticed this going on sale for $93, and I ended up getting it at Newegg's eBay store for a paltry $74 after 10% off from a coupon and 10% Bucks and it's impressed me a decent bit so far.
Anyone got any info on these? Thanks so much in advance!
EDIT: so far I've been able to do 3200MHz with somewhat tighter primaries than XMP stable. Secondaries set to XMP. Gonna keep testing this stuff and report my findings!
