Re: UMC chipset PCI 486 mobo. AMD P90 CPU options?

Nice necropost. If you read Feipoas utlimate 486 thread, he has a pretty good writeup on this board. In short, 66MHz appears to be stable, at least on his revision. He's been running at 66MHz for years and it still works. The maximum RAM is 256MB. Feipoa's board has been modified to accept 1024kb …

Thanks. I'd like to buy it. 256 MB means 4*64MB EDO RAM. I would like to 512 MB on this old chipset of UMC. What about new layout this motherbord with some memory mappers? It could help handling much more RAM and cache memory up to 2MB. Only wright BIOS to flash remaining. This won't work. There …

Thanks a lot again. Does exist wright another chipset of UMC with all demand features anyway? I mean other motherbord? I have had about 15 years Intel Pentium II MMX at 233MHz on Microstar MS6119 and Intel 440BX chipset. All the time I have been used FSB 66MHz. Motherbord had 3 memory banks for 256 …

Got ~4600 points with the right driver and GF3Ti200. And about 100 points more with Quadro2Pro. Now, I’m learning how to apply 2-2-2-5 delays to RAM and other tweaks via WPCREDIT. 07F3C9B8-73C9-4659-9442-52763DF1A6FD.jpeg 6776109C-9090-4C04-8E14-E5341960E7A1.jpeg UPDATE: I've managed to set 2-2-2-5 …

Thats the spirit 😁 Good work! Care to share photo of your CPU? And is that score with 112x5.5 or 124x5 or 133x4.5? My best score with MVP3-M is 4800+ with 112x5.5 Try this to tweak maybe. https://drive.google.com/file/d/1VI9ot2yN9v1h … iew?usp=sharing

My last step will be Liquid Nitrogen 😁 120x6 = 720Mhz The dream is to get 6000 points! And when is that red beast arriving?? Mentat, try Geforce 3 Ti. How did you get fast write on? Any side band? Can you make me a screen shot with WPCredit?

You must run GF3 Ti200 @ Ti500 clocks it is then faster than GF2 But now you have me thinking of using GF2 with big overclock :D That is a very high voltage for that overclock! Its touching the dangerous side. I am so excited about the motherboard that you are getting! I have been looking for one …

Easiest way to check if board or cpu is working is to have second board/cpu. POST diagnostic card would help here to see, if anything is happening on the board...

What are those electrolytic caps? They look nasty and cheap, should be replaced. If you do not put anything in the board (no CPU, no memory) is it beeping with low long beeps? If you just put in the CPU (no memory) is it beeping? My M321 was notoriously sensitive for memory. I have had one, lucky me …
