Hello there,it seems that some pins underneath the mobo had been crashed and the mobo would not start with the power button.It seems to power on Okey with the ps on ground pin trick.I will post tomorrow pictures.It is a very nice motherboard and actually my first pc hardware.

Hello Vogoners , back in 2017 I wanted to revive my first PC ever in it's original config since I never let away my originals setups.Back.in 1997 after the dead end of my trusty amigas and I had since 1997 and still have even a power PC 604e 233mhz for my Amiga 4000 in the cyberstorm ppc , I had a qdi titanium IIIB stuffed with an Intel pentium 233mmx , buffed with a diamond fire gl 1000pro ,permedia 2 , 8mb vga , a voodoo1 4mb an awe64 ,even a scsi 2940 and 64mb ram.It was a Ferrari for a villager in Ioannina Greece! Well, I had perfect grades and an even better than perfect character beith at an age of 14-15 years old.Anyway my second set up after a year? was a superb Asus p5a ,AMD k6-2 400mhz which by 2001 I had upgraded to ....well by 2001 I already had sever slot A amds and dual p3 and even a dual Celeron 533 trying to install p3s with the powerleaps neo s370 claiming to be amp compatible....anyway by 2001 I had upgraded to AMD k6-3+ 450 oc to 600 and I had the plain AMD k6-2 cxt core in the drawer .At that time and always the sysopt forums had tons on info and even more the perfect amdzone forums !!!!! All leading to the genius Jan steunebrink ,the godfather of the socket 7 era motherboards and he managed to prepare for me the patched J2 bios for the qdi titanium iiib .Even thought the bios was programmed correctly , the AMD k6-2 never worked.Fast forward to 2017 I am reving my first PC love and really feel vorgon again , this time with 256mb ram and a bigger scsi hard disk yet I left a comment here if I could use the cxt core to my board.Later on the history brought us the Tillamook dream and I among others enjoyed a last upgrade for out 430 tx , vx , hx era boards.300mhz babies , tomb raider Lara croft and the need for speed II SE at its best for one last time before paradise .The perfect life reached 2024 and I got message from Mr chkcpu claiming to be Jan ,yes , the godfather of socket 7 mobos and that he had prepared for the qdi titanium iiib b a newer patched bios with a working AMD k6-2 cxt plus core routine along with 83mhz fsb while out qdi topped up to 75mhz.And behold .I made up my mind , once I will even the vahalla , along with c64, amstrad6128plus and my amigas , I will be carrying the qdi titanium iiib and of course hang out with Jan .Well , I am that thrilled and admit it , this Jan Steunebrink never stops give new life to our trusty socket 7 era motherboards.Our perfect hobby.Vogoners ,admit it,we have much more fun that Ferrari owners !

Thank you Mr Jan Steunebrink for always keepimg the socket7 momentum going.I pulled out from the drawer the cxt k6-2 core and try to straighten the pins with a mechanical pencil method.more than 24 years sitting in the same drawer.

Intel Tillamook 266mhz oc to 4*83mhz aka 333mhz rock solid.Fingers crossed to test me 400mhz k6-2 and later on install one of my AMD k6-3+ which I have in an Asus p5a , sun cobalt qube3 and Compaq pressario 1692 and some pieces in the drawer since I have both ahz and atz cores.

It works and it is alive ! AMD k6-2 300mhz , I guess my 400mhz cxt core has been lost forever .Mr Jan , 100% success ! How about 2 days vacations to my small hotel for free in Greece? You deserve it .

AMD k6-2 400mhz

Hello amijim,

Thank you for the kind words. I like this BIOS patching hobby but it takes a lot of my spare time so it’s nice to hear that it is appreciated. 😀

In turn, I have to thank two other people who’s work made this patched Titanium IIIB BIOS possible.
The first is scorp who runs the Necroware YT channel. His help was essential in the discovery of how to get Vcore control below 2.8V via software. He used the Titanium IB baby AT twin board of the ATX Titanium IIIB to test the many possibilities.
Second is GeorgeMan who tested a patch J2.5 interim BIOS on his Titanium IIIB. This testing confirmed that the TIB and TIIIB boards and BIOSes are largely compatible and that I could use the improvements I made for the Titanium IB on the IIIB as well.

@amijim, test results of the QDI Titanium IIIB patch J.3 BIOS look good. When you are able to test with a K6-III+, I like to see those results as well.

For those who are not familiar with these jumperless socket 7 boards, it appeared to be a big challenge to alter the BIOS control for FSB, Multiplier, and especially Vcore.
Having looked at jumperless socket 7 BIOSes from Abit, QDI, and Shuttle, I was surprised by the different implementations of the jumperless control on these boards. Clearly, the basic Award v4.5xPG core didn’t include jumperless control, so each motherboard manufacturer had to design their own solution.

QDI went very far with their SpeedEasy Technology, implementing the most automatic control of FSB, multiplier, and Vcore for each CPU model and stepping. Only the speed rating of the installed CPU had to be entered in the BIOS.
In addition, manual control of FSB, multiplier, and Vcore is provided via the BIOS as well. This makes the SpeedEasy BIOS code quite complex.

So this turned into quite a project that kept me busy for several months.
I applied 21! patches to both the TIB and TIIIB BIOS, more than I ever did on any BIOS. 😉
But the lower Vcore support already accounts for 8 of these patches…
The most important mods for the Titanium IB and IIIB are:
- a fix for the K6-2(+)/III(+) bootloop issue
- addition of 2.0V to 2.5V Vcore support in 0.1V steps for all lower Vcore K6 models
- addition of 83MHz Bus Clock support
- added support for K6 Model 7, K6-2(+)/III(+), and WinChip 2 CPUs.

The Titanium IB patch J.3 BIOS is already available on my Unofficial K6-2+/III+ webpage and the Titanium IIIB patch J.3 BIOS will be released soon.

Cheers, Jan

GeorgeMan is a Greek guy who asked me your patched bios two years ago.I already sent him the j3 bios.Tomorrow I will install the l6+3+ for you.

I think that Jans bios is more stable than ever.Amd k6+2 300mhz cxt core oc to 500mhz !

Hi amijim,

Okay, you got the board up to its maximum 500MHz speed (6 x 83FSB)! 😀

And overclocking a K6-2CXT/300 to 500MHz is very nice. My K6-2CXT/350 wouldn’t go above 450MHz. What Vcore did you set for this overclock?

About the SpeedEasy Vcore setting in the patch J.3 BIOS, I don’t know if I explained this before, but in AUTO the K6 model 7 and all K6-2(+)/III(+) models now get 2.1V Vcore by default. I considered this a good and safe start value for these CPUs.
So I did not add extra logic to differentiate between 2.0V/2.1/2.2V/2.3V/2.4V models. These voltages can then be set Manually in the SpeedEasy menu after the first boot.

Cheers, Jan

For Jan.Stay tuned .

It is the time.

Benchmark time

Well , even though the benchmarks are almost the same on AMD k6-2 500mhz and AMD k6-3+ 500mhz , the real usage seems much quicker on k6+3+ .Can this because I have 256mb ram on Intel 430tx that can cache up to 64mb ram? My board and all 430tx boards have a tag ram of 64kb while the 430hx have a tag ram of 256kb.Has anyone tried to install a 256kb tag ram on the 430tx? Is there any software than can tell us how much ram is cachable on the running setup?

Edit.It seems that I misunderstood my picture with a VX board I had to get the pins straighten and thought it was my qdi titanium iiib motherboard .There is no tag memory on the qdi that I can change from 64 to 256.

Hi amijim,

Thanks for the K6-III+ test as well, looks perfect! 😀
As you have noticed, the K6-III+/450 runs fine at 500Mz and you don’t even have to increase the Vcore above 2.0V.

The cacheable limit of the onboard L2 cache on this board is 64MB. This is a i430TX chipset limitation, so no amount of Tag RAM can increase that. Decreasing the amount of RAM on an i403TX board to 64MB will increase performance when using a CPU with only L1 cache like the K6-2.
However, with the K6-III+ you get an extra 256KB of L2 cache inside the CPU that runs at the CPU clockspeed. This fast L2 cache has a cacheable range of 4GB, just like the L1 cache.
The cache on the motherboard now becomes a L3 cache and doesn’t add much to the total performance. This means that with a CPU with internal L1 and L2 cache, like the K6-2+/K6-III(+), you can use the maximum 256MB of RAM on this board without losing performance.

I consider this Titanium IIIB patch J.3 BIOS now thoroughly tested and will publish it on my k6plus page at the next update.

Thanks and enjoy!
Jan

Wait, so the K6-II and III can be used to circumvent the TX's (cacheable) RAM limit?

In that case, I know what upgrade my ABIT AB-TX5 is gonna get 🤣

Let another k6 story begin , Mr Jan ,Mr PcBytes need your help!

Dear Jan ,
Yes the bios is completely stable , I would say more stable than with the 233mmx and the original 1.2s bios.I would like to ask you though if you can add support for the Tillamook cpu that I have and there was a very big effort here in Vogons to make them work on every socket 7 board.The whole story took years and we can now mod the Tillamook cpu to have a locked 4x multiplyer , a dual plane vcc and separate io core and actually the qdi is extremely stable and happy with it.The J3 bios is actually missing only the correct name and cpu speed and the correct vcore.providing 2.8 v. instead of 2.0v .I am sending you a picture of the mod if you can do this little extra mod for this qdi motherboard for me and all the community.Thank you , my first love has now a new era for me to enjoy.Thank you.
