Quick mobile post, but I'm mildly annoyed that I'll probably need liquid cooling if I want it quiet. I guess my last attempt to air cool it might be to upgrade from my Ninja 4 to a D15 (or maybe U15S as I already have some industrial Noctua 140mm fans I've been trying to tame the 7900X with)
Not yet, but definitely in the planning..
The 7900X is quoted for a Tdp of no less than 170 Watt..... I'd take a Noctua NH-D15 with added third fan if I were you!Quote:

I kind of wish there were medical projects that could utilize the Ryzen 8000G series NPU (if it's *actually* useful in some way)
Rumour has it that upcoming BOINC 8 will/might have NPU supportQuote:

There are no less then 34 A620 boards, of which the weakest in features -the Asrock A620M-HDV/M.2- has CPU power limit of 65 Watt, a mere 2 RAM slots supporting a maximum of 64 GB DDR5 (and this at a mere 5600+ speed), and a 4+1+1 power phase design at a maximum of 50A without VRM heatsinks. This does not prevent the board from being able to support a Ryzen 7 8700G, but there are better -more expensive- choices.
A tad better -but unavailable here- is the MSI Pro A620M-C EX: a 90(?) Watt CPU power limit, the 2 RAM slots supporting 96 GB DDR5 (but at 7800+ speed), a 6+2+1 power phase design with the VRMs rated between 55A to 80A. No VRM heatsinks here either.
The more basic but available MSI Pro A620M-E is the cheapest A620 board here, and a little bit better than the Asrock A620M-HDV/M.2.
Another board that's better is the Asrock A620M-HDV/M.2+: a 120 Watt CPU power limit, the 2 RAM slots supporting 64 GB DDR5 (but at 6400+ speed), a 2x3+2+1 power phase design rated at 50A. And finally: A single heatsink, for the VCore VRMs.
Price-wise (over here) I've passed two Gigabyte boards (A620M S2H and A620M H) that officially have no power limit, but whose 5+2+2 power phase design has VRMs rated between 49A and 69A. Again no VRM heatsinks here.
Also cheaper than the Asrock A620M-HDV/M.2+ here: the ASUS PRO A620M-DASH-CSM and the Prime A620M-K. They have nearly identical specs, the Dash looking very retro with its green PCB, the Prime very ASUS basic. They both have a 120 Watt CPU power limit, the 2 RAM slots supporting 96 GB DDR5 (but at 6400+ speed), a 2x4+2+1 power phase design with a weird mix of VRMs rated between 25A and 58A (VCore), 46A and 69A (Soc) and 50A (Misc.) And finally: Again... no VRM heatsinks here.
This changes with my personal favorite till now: the ASRock A620M Pro RS. A 170 Watt CPU power limit, the 4 RAM slots supporting 128 GB DDR5 (but at a mere 6000+ speed), a 2x3+2+1 power phase design rated at 50A and heatsinks for both the Soc, VCore and Misc VRMs.
If you want 4G per thread and a Ryzen 7 8700G that is enough and you might even extend your RAM reservation to 8 GB per thread. But...the max supported RAM speed is mediocre.
If you want Asrock, at least one big VRM heatsink AND fast RAM, you could choose the A620I Lightning WiFi ITX board: 170 Watt CPU power limit, the 2 RAM slots supporting 96 GB DDR5 (but at 7200+ speed), the 8+2+1 power phase design rated at 60A and a big heatsink for the VCore VRMs, so you might even want to try it with a 12-core Ryzen 9 5900 and a dedicated Video Card...If you just want to build an APU cruncher and therefore need faster RAM than 6000 MHz (spreadsheet) or MT/s (store) you can go a step further up: the ASRock B650M Pro RS. The same power phase design and VRM heatsinks, but the RAM still maxes out at a shitty 6000 MHz (spreadsheet) or MT/s (store). It can take 192 GB as a bonus, has a 2.5Gb ethernet port and it is able to support a PCIe 5.0 x4 M.2 SSD, provided.....you're using a Ryzen 7000 series CPU, not a 8000 series APU. The full-size ATX version does support RAM up to 6400 MHz (spreadsheet) or MT/s (store) -the version with WiFi even does 7200 MHz (spreadsheet) or MT/s (store).
The only other A620 board with full VRM heatsinks is the ASUS TUF Gaming A620-Pro WiFi, an ATX board at a price level of the cheaper B650 boards. Its 4 RAM slots support 192 GB DDR5 (but at 6400+ speed), its 2x6+1+1 power phase design is rated at 50A.
Here's the ASRock's line-up of their X870 and X870E boards https://www.techpowerup.com/323134/c...ht-in-the-open
Here's MSI's https://www.techpowerup.com/323116/m...ies-processors
if my A620M S2H can't withstand a 7900X, i'm kind of questioning the A620 Pro RS could. definitely couldn't do a 16 core. and if you're going as high in cost as an A620 TUF Gaming Pro, might as well go cheap B650. i think the B650M-HDV/M.2 is as low as you can go and still power a 16 core 24/7 without server fans blowing over the VRM
The only thing my A620M Pro RS is incapable off is running overclock settings for the Ryzen 7 8700G -but that comes with the A620 chipset. I expect better results with the Asrock B650 Pro RS.Quote:
