Yes prices for K6-3s are very crazy, even for the K6-2s. But... The SS7 It's the best platform for Windows 9x and pure DOS. I have two PIIIs at 550 MHz, Coppermine and Katmai for Slot 1 and the very good Aopen AX6BC plus motherboard, but due to locked multipliers of the cpus, SS7 is the best …

@athlon-power The cpu cooler is pulled off from a S370 board and a Celeron 450 MHz and I'm using the Mx-4 already. I also strengthen the heatsink connectors to the socket connectors. I will try to reduce the voltage to 2.5V and do some stress tests. I have two K6-2 at 450 MHz one from 1998 and one …

On November of 2018 I replaced to the 5EMA+ all capacitors and the board is like new, only issue is that the ps/2 ports (I have mentioned it to another …

The PSU moves some hot air from the case outside, but I can use a silent slot fan. I will make a try. Thank you.

I was wondering if I use the Am5x86 CPU on my 486 VLB build and downclock it to 66 MHz will the fan and heatsink be required? I'm asking that because due to the position of the cpu socket on the QDI motherboard which I replaced a Soyo one recently, I cannot use a fan and heatsink because the floppy …

Very nice build! The paint job looks pretty slick, what was your process for painting / what supplies did you use? I've cleaned all the plastics with dishwashing liquid and let them to dry. Then I've used a spray with plastic primer based on water for all the plastic components I wanted to paint on …

I know many people during the 1995 to early 1997 period that they were using Windows 95 on their Dx2 or Dx4 486 cpu. I have Windows 3.11 FWG installed to my 386Dx40.build. It's the B version and runs great on this system. Only for DOS gaming. I own the Am5x86 you mentioned. I have an MMx.build for …

I've replaced the motherboard with the QDI V4P895GRN/SMT V1.0 (S1.1) and everything works without issues. I think it's a very good motherboard for my purposes and has a voltage regulator, but It doesn't run the Dx2 to 80 MHz like the Soyo, the system hangs, so I running it to stock 66 MHz. I removed …

Until the middle of 1997 most users were buying the slow Pentium chips. Also AM486DX4 were pretty common along with the AM5x86 chips during the 1995 - 1997 period. Pentium and Pentium MMx prices were dropped significantly during the last months of 1997 as I can recall.

PIII@500 MHz with 256 MB RAM, Voodoo 3 3000 AGP, and SB Live! is period accurate for a Windows 98 SE build I think. Voodoo 3's came to public on summer of 1999 and Windows 98 SE on May of 1999. I use a k6-3 build with the parts I mentioned for this period, but I will try the PIII at 500 MHz sometime …

I don't want to use mechanical old drives that would die for sure someday. I finally found twenty days ago my ST3660a from 1995 which it was installed on my i386Dx25, which it was in use until July of 1998, when I switched to Pentium MMx, it was withdrawn on 2001 from the MMx which it had my fathers …

Thanks.. But, I believe that AWE64 Gold is an overkill for my setup and may be incompatible. Bios has no option for PnP setup or ICU. When I'm inserting the ESS 1868F I have no issues at all, even with the Terratec 16/96 Gold. I've tried with the CTCU.EXE to change the resources but the problem …

Thank you everyone..! But... I'm experiencing issues with the AWE64.. No sound and the mouse isn't working sometimes.. The build worked great last time I play with it, two weeks ago. I think it has to do with IRQ conflicts between the PT-627 and the AWE64. The same happens using the DTC 2278 S/D …
