Hi all   I wasn't lucky with Abit for sA benchmarking - they never survived more than a few days (had several ones, ones I remember were fully modded from moose83 and stock one from Ananerbe

After I stumbled over over a Toshiba DDR PC2100 stick on german ebay, which had exact the same looking of the typical Winbond IC, I think Winbond are actually Toshiba. The ICs were labeled with produc

Those Geil refuse 1t on nf2 and nf4

I've run Geil Ultra-X (2x512mb TCCDs) at 250MHz 3-3-3 1T on NF2 through 32M ;) The A7N8X doesn't seem to like CL2.5 with Merlin Romsips... I've had 2.5-3-3  250MHz 24/7 stable on DFI Infinity years ago. It's achievable for sure :) Booting them above that isn't an issue, but getting it stable enoughfor 32M is... TCCDs are very picky and the NF2 just doesn't like them at all.

From what I saw the mem controller in the nb chip is very picky. One can handle something, others can not. But there are kits who seem to do better overall. 
I noticed this week that my Epox board likes ds 256MB memory more then ss. My Abit boards like ss more.

Anyone care to mod an Epox bios ... (or anyone already have a modded one) ?

It's about the EP-8RDA3I (non Pro) ... sample photo

Дънна платка Epox EP-8RDA3I Socket 462 | Компютърни компоненти ...

It's the board without the Sata ports

... and has the older 256kb bios.

The latest version available is the rda34729.bin (29/07/2004)

Yes. I got a A7N8X-E Deluxe which won't run 210Mhz fsb without voltmods. The silicon quality seems to fluctuate a lot... With mod it can't reach 220Mhz. Must be the worst -E Deluxe ever made.

That is probably the worst I have “seen”. I reccomend testing all Winbond dimms you have and maybe tccd as well. In my experience there could be 1 or 2 dimms that run great and surprise you.

I modded your BIOS for the EPOX 8RDA3I. Before flashing, please make sure, that CMOS register 73-78 are free. You can check it with this program. It should look something like this (in this screen CMOS register 73-78 are used by my mod):

image.thumb.jpeg.bb43acaf9839eece00ef74681f842069.jpeg

Some things left to say:

  • the FSB Frequency is limited in the BIOS by 250MHz.
  • 256KB BIOS!
  • BPL is 3.09 by default, I left it in the original version. I do not own good BPL Versions for 256kb BIOSes.
  • This BIOS versions should work, but they are completely untested! I will not be responsible for any damages! Having a programmed backup bios chip before flashing is not a bad idea.

Thank you

I will test your bios next weekend.

Yes i already have a pre-programmed backup bios chip for this board.

Ok so we talk about alternatives. And yes, dfi is expensive when found... 

So I bought this defective board for €80... and it is working again (without Firewire 😁😱).

Expensive. Needs a re-cap badly.

Pretty much all my Ultra B is good for is high FSB and SPI. I use other boards for everything else.

Well since last time I had seen one being sold was at least a year ago and that one did €180-200. 
So €80 for defective is expensive, for working board is Ok. 
I am hoping so that it does a nice job in fsb speeds. 

Oh and I recap myself. I had caps allready. I would not turn this on before.

What do you guys now about Epox 8RDAx PRO boards? There is almost no info about them, looks like they were the latest Epox boards on S462. I think they may have different MCP.

For sure they have better CPU VRM, 4 chokes instead of 3 and quite a lot of Mosfets in RAM VRM.

I can tell you they were good boards, when you got a good one. They all suffered from Epox sudden death syndrome, and were just as temperamental as the DFI boards.

Pretty much just as hard to find as an Ultra B right now.

Not really, there are at least 3 here in Poland for sale at this moment for not much money (less than 25 euro). I may take one or two and check. I think people confuse it like I do with regular 8RDA which was very common.
