Hm...these four boards are some of the latest and fastest with full Win98(SE)/ME support (except the Realtek HDA High Definition Audio Codecs). I would always prefer DDR400 on these boards as they don't support DDR2 800. But yes, that all just makes sense if you need/want the Win9x support - else it's better to chose an Intel P35 board f.e.

Thanks, but I already have a fast, almost too fast Socket A PC for Windows 98SE. At some point, the additional speed no longer provides any benefit. On the contrary, the faster the PC is, the fewer old games work. And without an ISA slot it's not a complete DOS PC anyway. Just my opinion: The 775DUAL VSTA or the 4Core variant are more suitable for an XP Retro PC.

It can't be fast enough (for me)... My fastest PC with Win98SE and full support has an Athlon 64 4000+ @3000 MHz on a ABIT AV8-3rd Eye, 2x 512 MiB RAM @DDR500 with GeForce 6800 GT/Ultra. I was always a friend of maxing out things. Concerning WinXP the limiter for me is the Classic AMI / Phoenix-Award BIOS - no way for (U)EFI.

What do you mean by Win98SE support? 98SE works like a charm on X58, as well as on P35.

I wouldn’t call ICH6 to 10 “charm” in the sense of DMA for PCI sound cards
The OS itself will install and run and you can get rid of unknown devices with a modded INF indeed.

Both have no Win9x driver support, so you only can use standard drivers. It may work for you like a charm but that's nothing for me. 😉

Another thing is that Win98SE supports just one CPU with one core - the only one core CPUs for LGA 775 are the Celeron 4x0. Sure, you can use dual or quad core CPUs and it will work (with Win9x seeing one core), but that's kind a pointless.

Can you tell more? I have SB Audigy 2 in my X58 and didn't face any issues. Maybe I am just not aware of them. 😀

What is missing when using standard drivers?

I don't like it to have no manufacturer drivers and f.e. using graphics with standard drivers w/o acceleration is pointless!?

This is driving more and more off-topic, we should come back to the thread's topic: "Asrock 775Dual VSTA & Core4Dual".

Sorry, I don't see your point.
Nothing stops you from installing drivers for supported GPUs, sound cards or others when using 98SE on P35 or X58. What is missing then?

I believe this is about pure DOS, not 98SE:

The ONLY and the MOST VITAL requirement of enabling legacy DOS audio support for capable PCI sound cards is that your motherboard MUST have a proper southbridge.

Which supported GPUs? The only PCIe GPU series with full official Win98SE support is nVidia GeForce 6 (there are unofficial ways to run ATI Radeon X series and nVidia GeForce 7 series, I know) and the only full supported CPU series for LGA 775 is Celeron 4x0, for LGA 1366 there's none I know. So if you like running Win98SE under such circumstances - just do it, I won't, as said above.

You don't need a CPU driver for CPU to work though ?
Also, you can disable cores and Hyper Threading within BIOS in almost (if not) all LGA 1366 boards.
Same goes for later generation ones obviously.

Radeon X8x0 series will run on official Catalyst 6.2 Win98 driver no problem (at least it did for me in my limited test I did).

We are talking about LGA 775 (the specific boards mentioned in the thread's title), not 1366. Disabling cores (which isn't necessary to run Win9x) has nothing to do with full (native) support...that's crippled support.

The Catalyst 6.2 itself is of course official, but the support for Radeon X GPUs is in beta stage (what I wouldn't call "official").

Radeons X800/850 work just fine in Win98 using the Catalyst 6.2. Both AGP and PCI-E, official or not, as long as it runs properly, who cares? And the same applies for CPUs - no need for native support - all core2 architecture based CPUs will run perfectly fine (with single core used of obviously). Also it is not pointless at all to run C2D because the extra cache and frequency makes huge performance increase compared to Conroe-L Celerons.

Also it is worth noting the late VIA AGP chipsets (PT880 included) ale likely to have bad AGP bus performance if using W98 due to the known BIOS/drivers bug.

Using pcie Radeon is a good idea because all ASRock dual boards have this
VIA zero bytes AGP memory bug | Navigation thread

And then there is this : LINK

If Radeon X series is working for you with Catalyst 6.2 then be happy - nevertheless it's beta software in that case, no matter if you care or not. It doesn't mean that it is something bad, f.e. I also recommend to use the latest beta 1.07.00b DX8 drivers instead of the latest official 1.07.00 DX7 drivers for 3dfx Voodoo3 cards. BTW many users shy away from installing beta software, I notice when analyzing the downloads from my website.

The rest is pointless, indeed... The discussion began with this post and if you read my postings before, I was talking about "full Win98(SE)/ME support" (the emphasis is on "full") and that has nothing to to with using one of two or four cores of a CPU.

Nobody said, that you can't run Win9x faster on more CPU clock and cache and if you do so then it's OK and fine...this wasn't the point.

BTW some OT:
Your Hardware Museum website is great, know it for many years and have linked it in my "links" section (-> https://soggi.org/misc/links.htm)! Thx for the work and especially the high res pictures!

1.4vcore mod at back side of motherboard socket

E5500 @ 4135 MHz (14*295FSB)
OCZ DDR2 3-3-3-8 1T
Sapphire 9550 @580core/405mem

Just done 1.5vcore mod to use E5700 @ 4.425MHz 😀

Hello all,

I see that around 775dual-vsta cpu socket there are 4 spots for caps.
It is worth to add them? Anyone tried?
