I’m thinking of a Windows XP build with a R9 280, FX-6300, Asrock 970 Pro3 mATX, 8 GB kit DDR3-1866/2133. The 970 board because there is XP chipset drivers, and the board is brand new old stock for $70. Youu can download from AMD’s support page Radeon 7950 XP drivers that work with a rebadge R9 280.

Wanted to put a warning for anyone considering RDNA2 for Windows 7 SP1 x64 use.

Radeon RX 6700 XT (trying to load CCC) :

Radeon RX 6950 XT :

^WDDM 1.1 support ("DDI = 9Ex"/DirectX 9.0c max. feature level support)

Crysis (OG) :

^Fails to launch with GeForce 5(FX) style error.

Conclusion :
DO NOT buy RDNA2 for Win7/Win10 dual boot systems (note : both tested cards are reference models).
Drivers are so broken you will pull your hairs out trying to make them work (not tested ALL RDNA2 cards, but after those two - I'm not going to).
+ They work fine under Windows 10 on the same settings/platform.

PS. RTX 30-series works fine under Win7.

Windows XP + Bulldozer/Vishera ?

EDIT: No go. 112 POSTs but as soon as WinME's bootscreen shows up (and 98SE does this too btw, I had a spare drive just in that case) it hard freezes. No amount of voltage bump seems to have allowed for more than 100.

I'm betting real money you could get 103mhz FSB out of it stable, maybe even 105mhz. If you dialed in the voltage just right. Don't give it more than 2.2V though. Most of the 300A's(not all) could get just above 100. Tinker with it some more, I'll bet it'll do it. Make sure you mount a faster 80mm fan on the heatsink though. Heat is limiting factor. Plenty of cooling is needed for stability with those Mendocino cores. Unless you're happy with 100FSB. Then hey, you're golden!

That's a very nice setup! I would go with the DDR3-1866. The gains you'd get from DDR3-2133 would marginal at best on that chipset/CPU combo. 1866 is dead cheap right now, 2133 isn't. Also, unless you already have the CPU, may I suggest an FX8300? The extra module(2cores/1FPU) will make a solid difference for some games(even on XP). Only a thought.

Yeah, an RTX 3070 seems to be the last all-rounder for Windows 7.

Wait, what do you mean? Seems like a solid combo to me. Am I missing something?
