The early Jan 1997 screenshot of the QDI ftp shows very few options
https://web.archive.org/web/19970130115152/http://www.qdigrp.com/html/bios.html
You are looking for this one (with UMC um8886f / um8881f chipset)
https://www.elhvb.com/webhq/models/486pci/p4u885.htm
Your best shot at the moment , is to test one of those bios that are still available at the old mobokive archive.
https://www.elhvb.com/mobokive/Archive/Qdi - Legend/bios/486/index.html
The worst scenario is that you will programm the new bios chip but the board will not start.
Start with the 885v23 , it was made for the P4U885P3 (it looks very similar to yours).

Very hard nowadays to find a 486 mobo bios.
Do you have the ability to check if a certain bios is the right for your board ?
Can you unzip and test with somekind of utility ?

Very good looking cascade unit !!!

Moved Start date to 1st of August , so you have 2 months to play
Well , the two month period is for people that dont plan to take a summer holiday and stay home i guess ?
But , most people (at least in Europe) usually plan their summer holidays in August.
Take that into consideration please.

Discounts are always nice.
Any link ?

Nice result , but submitted to wrong cpu category.
These cpu's are Pentium EB (fsb 133) not E (fsb 100)

Congrats once more !!!

What can you advise?
I have compiled a short list of possible applicants:
Why no Gigabyte Soc Force in the list ?

Well done !!
Looks like a strong result for a PII

That's it.
Have fun !!!

You replace the input frequency of 14.318MHz that goes to PLL with a custom one. This shifts all the clocks from the PLL. Breaking the timer, USB, floppy. Thus, you need to provide stock 14.318 (system timer), 24MHz (floppy?) and 48MHz (USB) as well to maintain these while other frequencies go up.
You shift only the base clock, the board's PLL does the rest.
Nope, should work with pretty much any PLL.
True
The pll device the Japanese firm FANATIC was selling back then as PLL01 , would require soldering to certain points , to take care of the different clocks for floppy and usb
For example the P3B-F

Limit of motherboard @150FSB, pin mod 2.8v
Yeah
That board with the HIP voltage regulator , did NOT have the easy mod of the FB sense pin (we perform in common cases).
As for the 150FSB limit ... TurboPLL only , area.

Well done.
Very nice score @DDC
P.S.
Hmmm ... million dollar question ?
Do i have this board in my collection ? Weekend pc-graveyard search cooming

It's kind of a common problem with validations on old systems.
The clock fluctuation is huge sometimes.
But we always submit what cpu-z reports in its database.
So , the correct score is 210.05

Nice job Obi !!!
P.S.
Looking at those category results (Slot-1 Celeron Convigton core) , what got my attention was @RemiKo results
All of his submitted results with the same? cpu , report a dB0 stepping and a 652 cpuid ... which belong to either a PII Deschute core or a PII Mobile Celeron (Convigton)
Regular Celeron Convigton cores are dA0 650 or dA1 651
Did we , on purpose left that category unified for both desktop and mobile cpu's ?

Can you guys spot what's wrong with this score ? take a guess ...
Becides all other already mentioned.
Scoring of first line "Seq" ... is not centered and there is also missing the MB/s

Samsung magician is ram cache, and guess what type of software is banned
You dont get the meaning of my posts.
Perhaps i dont express myself correctly.
I know very well what is allowed and what's not.
Dont focus to score as numbers (score is out of line cause of the Samsung rapid mode).
Focus on the variation of scoring that i am reporting.
-
Start running each subtest alone ... and re-run and re-run , and you will see miracles happening
* and , yes i confirmed that the pc i tested had Samsung magician installed , with rapid mode enabled.

Did you install the Samsung sata ssd driver?
10 hours ago, Leeghoofd said:And that is without any caching software ? Hard to believe...
These tests were performed on a office pc , that is used for logistics and internet.
I have no clue if there is any kind of extra software installed , but i will check next time.

I did 3 runs within a 10min period with a single Samsung 860 Evo on a Sata2 controler.
1st run scored 1611
2nd scored 1962
3rd scored 3071
?
Which one should i submit ?

Are we really sure about this benchmark ... ?
Is it tested enough ?
Does it produce consistent results or are we playing lottery once more ?
I get different results each time i run it ... and i'm also getting big difference in scoring when running each subtest alone

You will need more than cooling , for a proper 3D session.
The board needs hardware mods for VRM section and Vdrop (voltage section is too weak).
Although , the best solution in an external voltage feed. (epower)
Good luck with your future testing and benching.

Congrats for a great result !!!
It looks like you have a very capable board also.
Have you tested if you can achieve similar frequency with a Conroe core ?
Wolfdale core might have helped a bit , i think.

Yes , the www.elhvb.com is a must have for all old-timers !!!
They host two bios databases , the mobokive and the kuriaki
and they also host many manuals for old boards.
They sure deserve a donation , for all support that they offer.
