Does the Asrock 775i65G support Core2Duo? The website doesn't list them among supported processors, but the manual does... 🤔

Depends on the revision? I think Rev 3.0 is one of the few i865 boards that supports 45nm C2D/C2Qs, or at least those with 800/1066FSB.

Isn't that the board that was the ultimate retro board until, oh, the pandemic or so? And that you could apparently buy new-in-box for reasonable prices in 2019?

I looked it up further and yes, it depends on the revision.

Looks like the Rev 2 supports C2D and C2X. Whereas Rev 3 adds support for C2Q.

I believe so. I think Phil did a video on it and suggested people grab them while available.

R2.0 and R3.0 have official support, 1.0 doesn't. Although you probably could just flash R2.0 bios and do pin-mod.

What will people try to play on an i875 they can not play on a Ryzen?

There are different levels of this. For some Win98 support ends with 925XE / ICH6 with 875/ICH5 being more legacy-friendly option and for others with x58 / ICH10 just because of IDE mode.

With patches and whatnot you can play anything on anything it’s not about compatibility at this point we are past that it’s all about the “feel” and similar mind games.

If we're pedantic about it, Intel Win9x compatibility mostly can be grouped into 4 classes of south bridges:

Class 1: PIIX family (Pentium 3 era with native ISA)

Class 2: ICH5 (last chipset with AGP and full support for various PCI DOS sound solutions)

Class 3: ICH7 (last south bridge with native IDE)

Class 4: ICH10 (last south bridge with unofficial support, classic BIOS, etc)

Everything not in these 4 is mostly redundant or hard to obtain.

Funnily, I have/had computers with classes 2, 3, and 4 - and not a single one of them ever ran Win9x. Maybe I should change that. 😁

Just wanted to point out that non-intel stuff chipsets are usually contemporary to one class but retain the compatibility of the former class..

I have Socket 775 DDR2 PCIe systems that run Win9x flawlessly..

Re-flashed the BIOS on my Asrock 775i65G R2.0 and enabled support for Core 2.

Tested it with an X6800 processor and seems to be working well.

I tried disabling L1 & L2 cache to see what sort of throttling capabilities it has. Playing around with multipliers and FSB settings, I get 3DBench scores ranging from 20.8 down to 5.9. That seems to put in the range of a slow 486 to a fast 286.

Tested Ultima 7 with cache disabled and it actually runs quite well. Probably on par with a 486 DX-33 from what I could tell.

Okay, but that's S775 already. S478 P4 is current. Directly disabled cache generally results in a jerk. The 775 is also fast enough for the SBEMU/CPUSPD combination, which gives a good result under DOS/WIN98. And natively. And here the awakening power is dominated.
As below.

S478 Flex :

S775 Flex :

Then the line can be continued on the P45/PCIe-> after the S2011V3, they are all strong enough for the above modern retro drivers ...and if not, conventional drives are recommended with older slowdowns.

However, I wrote that your configuration is too slow for modern SBEMU, which is good for more modern machines.

But I didn't mention SBEMU. I am a little confused here.

Oops, really, I'm so in that thread. I should have just mentioned the CPUSPD ...
Edit: I clicked in the wrong place, I should have been in the other tops.
