Avoid the weird server sticks. The one you linked is the one you want probably.
If you can get the onboard pll to do higher than 66mhz please share it in Pentium MMX 233 aiming for the stars! you will likely have to set it via hardware. Pull up/pull down.

The GA 586DX is not picky about RAM. You can use most EDO and FPM modules, if you want to max memory out with 4 x 128MB you will probably have to use FPM sticks. The difference in performance is very very small. Make sure you have the latest BIOS for maximum compatibility.
I doubt you can run this board at 75 or 83 MHz FSB. It doesn´t even have settings for that and the highest mustiplier is x3.5. So you´re restricted to 2 x Pentium MMX 233 (1.5 x 66 setting).
I run sticks that look just like that and have same specs (may be the same ones) in my tyan s1564D Edo, 60ns same size and numbet of chips. 5v and have all supported 512mb filled up. It has the same chipset as the 586dx
Devices like the multiplier mini or a interposer (see pcb projects in sig) can allow you to set any supported multiplier by the cpu. The 586dx I’m pretty sure would support most if not all super socket 7 cpus, if only at 66mhz bus. The linear regulators might be a weak point but there are ways to upgrade them. Bios support of said cpus may be lacking. But other than that, I don’t see why a tillamook at 66x4, a cyrix 366 at 66x4 or a k6-3/3+ at 66x6 couldn’t be made to work. Provided you could get the proper voltage programmed or upgraded to.

These should be working perfectly. Since the chips are 8MB you need 16 chips for a 128MB stick so they will be double-sided.
I use very similar 128MB sticks (IBM) on my GA-586DX (with Samsung chips and parity) and never had any problems - except for one stick:
Any chance repairing 128MB FPM-SIMMS with parity?
What CPU(s) are you going to use for FSB overclocking?
If the clock generator is capable of 75 or 83 MHz, this doesn´t mean the chipset, cache- and TAG-chips can handle this. Intel´s 430HX chipset is a bad overclocker...
Indeed. A k6-3/2+/3+ might shine with disabled on-motherboard cache, and disabled onboard devices in favor of add in cards. Sata, pata, etc.
My guess is that 75 may work, but 83 may be asynchronous and cause a no post. That’s what I saw on my p55xb2 when I forced settings via the pins directly. 83 may be too much for it anyway.
