Woohoo, the improbable Ryzen system is alive, with motherboard from Amazon sale, rando loose cpu from FB rando, thrift store DDR4 kit AND 2023 pulls from an IT worker ddr4 kit freebie. Also tested a thrifted single 8GB crucial stick and that seemed good too. It's still just on the mobo tray with temp GPU while I screw around with testing RAM and making sure things fitted to case.
It's definitely working fine at 2133 lowest common denominator RAM speed, the highest JEDEC one in the Teamgroup pair, and the default of the Samsung/HP pair of "generics". What I am not sure of is whether settings are sticking or not, tried going up to 2800, because the XMP on the teamgroup is a long ways from X at 2600, default volts, and the Samsung chips appear to be the 4Gbit famed "B" dies that take all the volts and go to 3800 or more. Anyway if the settings stuck they did one pass of memtest86 like that. Wondering if I should find out which OC modules used Samsung and what their XMP is, and copy it.
But anyway, got Ryzen 5 1500X going on 32GB on a B550 mATX board and need to get it fully buttoned up into the case and Ubuntu Trashpanda installed.
Ryzen 5500 looks like rather sweet 125$ 6c/12t upgrade for that (the 1500X could probably be sold to recoup some $$$). Even a 5900 XT with 16c/12t is like 400$. That being said, if the objective is make it the best bargain bin/yard sale build (fits the origin story of the parts you mention) that you can, don't change a thing.
Yeah the original intent was to throw that $30 1500x on a $30 first gen board, but there's just none of those around, they all fried or something. Stupid market round here, I could literally see the board I got new off Amazon for $80 in some amazon days sale, get put up on FB marketplace for $130 well used. Then DDR4 price went cray cray, I was already sitting on that free pair of 8GB Samsungs, though if I had looked up about the chips back THEN, I would have asked him for more. He was saying he had a shoebox full he didn't know what to do with at that time. We were joking about he could have set himself up on a Caribbean island if he'd kept them. Though those specific HP/Samsung are supposed to be kicking around on eBay in quantity, around the same pricing as generic generics.
So 16GB was feeling a little tight and I lucked into the Teamgroup T-force Vulkan Z kit at a thrift store, suspiciously marked down to $50 from $79 so I wasn't expecting much. Turns out those are meant to have Micron 8Gbit "E" dies, which clock different than the Samsungs. Samsungs seem to be all about voltage and tight timings and clocks don't go amazing high, the Microns do loose timings and insane clocks and don't like so much voltage. It looks like the lines cross at about 3600 with prolly 16-18-18 timings on 1.35V or 1.4 if needed. However, if I come across a pair of either Micron or Samsung based modules cheap, I might go fully one way or the other, otherwise I'm holding my nose playing EB Games *badum tish*
Holding off on CPU buy unless one comes up real cheap. Missed a bent pin Ryzen9 for $50 in the middle of summer, damn thing had been listed weeks too, just discover it and it's gone in a day. Gonna be throwing AI loads at this thing and I want to see specifically how it struggles and does well. Maybe I'll decide to go nuts on CPU, 5800x3d or something or maybe I'll re-platform to get PCIe 4.0 for better GPU bandwidth. Those Memory Express combo deals looking tasty for current insanity.
Think I'm gonna boot Ubuntu off a shitty small SATA SSD and have a high speed data share partition with Windoze on half a 1TB m.2 drive. Got one earlier last year for what now seems the impossible price of $90. I was thinking about pairing two 250GB SATA SSDs in RAID 0, but since that would struggle to make a TB/sec and the m.2 should do 3Tb/sec on this interface (actually capable of near 4, but on PCIe 4.0 derived slot) there didn't seem to be much point. Guess the balls out haswell board gets those since it can't m.2.
GPU going in hopefully is a R9 295x2, it's a bit of a squeeze. Found a brute PSU, it says it's headline output is 750W but it can put 744W to single rail 12V so that should feed it okay. Corsair TX750M.
Edit: I should kind of admit I bought the wrong chip, I wanted one of the first tranche of Ryzen CPUs "for posterity" kinda because they were cool and significant, but I didn't realise the 1500x came out a month or so after the first, first Ryzens, so I messed that up a tad. If I'm gonna try again to get it right I might get a 1st gen 7.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
