Cheap boards with faulty capacitors are not worth it in general. It would have to be DFI, Asus, Abit, Epox. Those can be expensive even with faulty caps as long as they are still stable (proves there isn't extensive damage).

Buy it only if you want a board to practice capacitor replacement.

These Asrock boards have great build quality. I use a K7S8X as my test board for graphics cards and CPUs, and I'm always liking how solid it feels for a budget board. System runs solid as well, with no lockups or driver issues, so that's the main theme here. It's not a bad looking board either.

In terms of performance, the Socket A boards with SiS chipsets tend to be on par with VIA and around 10% lower than Nforce boards. My biggest gripe is that they allow no overclocking and tweaking at all - no multiplier setting, no voltage setting, no FSB and RAM overclocking. To me, Socket A is the ultimate overclocking platform, so you're missing out on all that fun.

Some other points to consider: No 3.3V AGP slot, and I can't remember if this chipset works with PCI sound cards that have DOS emulation (this is why I hate nForce).

So is it worth it? In terms of monetary / collector's value, it's close to zero because it's probably the most common Socket A board you can find. With bulging capacitors, I wouldn't pay anything for it. But again, solid board if you just want a system that works and you're not much into overclocking. Pair it with a Radeon 9500 or Geforce 4 MX for that authentic early 2000s budget PC vibe.

Thanks for your answers, guys!

I forgot to mention, that this Asrock K7S8X socket A board actually has CPU multiplier ans FSB (including FSB 400MHz) settings jumpers. It was cheaper board variant, when it was new, but this doesn't mean, that it's a bad board in general. The question is not about if it's collector's item - obviously it is not 😀 It's about a descent motherboard for building a socket A system.

I already have even cheaper board with better SiS 748 chipset (this one officially supports 200MHz - FSB 400MHz) and it's not that terribly bad, even if it's ECS/PCChips branded, but lacks any overclocking settings.

The only thing that still concerns me about buying the Asrock K7S8X board is, if it will still run stable with overclocked SiS 746FX chipset at 200MHz (AFIK it lacks CPU and chipset voltage settings)? If not, I'll probably pass buying it.

P.S. I think, that the better K7S8XE model comes with SiS 748 and official 400MHz FSB support, but unfortunately there's no other descent socket A cheap boards listed for a low price, except this K7S8X model with inferior 476FX chipset (officially up to 333MHz FSB).

I just wanted to curb your enthusiasm a little in case you thought you found a holy grail, 🤣.

I have a K7S8X 3.01 (also a K7S8XE+). Until your post, I didn't even know it had jumpers to change the multiplier, it's better than I thought. According to the manual, it also allows incremental FSB overclocking in BIOS, though I don't remember seeing this option at all. I doubt it can do 200, but with that option, we could test if it reaches 180-190 maybe. I can test it tomorrow, the board is still ready to go with CPU and RAM installed.

Nope, I'm not here for the hardware Holy Grail hunt 😉 I just like to restore (and play with) retro PC stuff, that was given for free by friends or bought for really cheap.

The CPU multiplier setting jumpers on Asrock K7S8X rev. 3.xx boards are labeled "FID0" to "FID4" and they are located in-line with the two FSB setting jumpers "FSB_SEL0" and "FSB_SEL1" ("FSB_SEL2" is missing and I'm wondering what it can give for FSB if restored). I've found this info in the user's manual and checked it by some hi-res pictures available online.

I'm appreciating your will to test the K7S8X board, if its SiS 746FX chipset can run stable at 200MHz frequency, so the CPU can run in synchronous mode with DDR400 memory sticks. This board looks promising. Please, give me some feedback tomorrow for your FSB test results.

Thank you!

Okay, here are the results *drumroll*:

FSB 180 is stable
FSB 185 boots 19/20 times (once it boots, it's stable)
FSB 190 boots 9/10 times
FSB 195 boots 4/10 times
FSB 200 no boot.

So I would consider FSB 180 the maximum for this board. A bit disappointing, but not unexpected. There's also an option "CPU Overvoltage" that can only be enabled or disabled, this simply adds a fixed +0.05V, better than nothing.

Edit: Something interesting happened. After letting it run for some time, the board seems to have become much more stable. It has just booted 30/30 times at FSB 193. Maybe the capacitors needed some time to wake up? FSB 194 seems to be a hard limit though, I can't get it to boot reliably at that speed no matter what.

Hi, @asdf53,
Thank you very much for testing your K7S8X rev. 3.xx SiS746FX with overclocked chipset and the feedback!

I suppose, that for these tests you didn't use "CPU Overvoltge" BIOS setting, as it has nothing to do with the NB chip. Stable 180HMz bus means 360MHz FSB, which is not bad for such a budget board with some limited o'c capabilities, I guess.

Now I'm wondering, if there's some hidden "NB Overvoltage" setting in the K7S8X's BIOS, which can be easily unlocked with tool like AMIBCP. I have to look into the final BIOS ver. 2.60, if such an option is available.

I think I can get the board from the listing up-and-running for about 11 euros total (including the shipment plus 3-4 brand new low ESR replacement capacitors), which seems like an Ok price for such a "toy".

If I can't run the board stable with more than 180MHz bus speed, I have another idea for it. My stupid cheapo ECS socket A board has SiS 748 chip, so one day I can try to swap the NB chips turning the K7S8X board into K7S8XE, which is even better variant 😀

Once again, thanks for helping me to make my decision, if it's worth buying this board.

Unfortunately K7S8X's AMI BIOS turns out to be problematic, when I tired to open it with AMIBCP. I got the same issue like the one described here 🙁
