Nice!

Now you just need a PODP3V to get it even lower. Good work!

I'm surprised it only takes 15 minutes to boot Windows XP!

You replace quartz 32 to 12MHz, I understood correctly?

How fast (_really_!!!) are the clock (watches)?

I want a video with seconds windows near real watches

If all is correct - you are the best!

Albeit no, you're the best in any case )

Thank you, guys! Yep, finally I get the validation with correct CPU clock It need to disable DMI in ini file (DMI=0), as Franck suggested, and then it display the correct clock. I did also a little trick - I start first CPU-Z with DMI=0, then changed DMI to 1 to show the bios mobo correctly in the mainboard window There are all the images I took: http://s923.photobucket.com/user/ax2cz/library/10MHz?sort=3&page=1

ludek -

Finally you did it !

Thanks, mate!

Why so anormous amount of mem?! 128 would be great even without pagefile

Why remove the memory anyway? I'm happy to overcomed the 256MB limit of i430TX and I did not need to touch the rams at all now Unless I get better rams (hint: ram ranks makes difference), they stay there. I cannot get them to lower timings, so unless I get more SDRAMs with 2+ ranks, then these rams stay there See Aida64 report: http://depositfiles.com/files/o06t2paka ( http://www.mediafire.com/?8xub1mvfp868497 )

Congrats my friend. How much mem is used by system when displaying desktop? I was able to reach 49 MB on XP with pagefile off

I believe I get notably lower. My WinNT (optimized by me) build is under 11MB even with 1024x768 res (256colors), but the WinXP build will be around 30MB or so... I will check that for you, when SuperPi 32M again crash on the cursed K5 at the end... ))

Nice!

Thanks! I believe I could get lower too...

I'm surprised it only takes 15 minutes to boot Windows XP!

Well, I optimized the Win to the bone, so... hopefully I could get it even faster with the CF card W/O the keyboard mod it took nearly 21min, see the vid bellow.

Dead Things -

Now you just need a PODP3V to get it even lower. Good work!

Indeed. 7.14MHz is possibility. Just get a Pentium Overdrive, force it to x1 multiplier and now the 7.14MHz will happen Should not be a problem... Also I use patched bios now, that support AMD K6 3+. These CPUs have software multiplier control. Only for DOS, yes, but one can create a boot selector with SetMul, where I set x2 multi and get 14.3MHz for AMD CPU.

The only catch is - I lack the K6 3+ But maybe next year...

You replace quartz 32 to 12MHz, I understood correctly?

Nope. What you see with the 12MHz crystal is mod to make input devices work, when the FSB is forced to REF/2 clocks, as the PLL chip support: http://www.vogons.org/viewtopic.php?f=46&t=42426&start=20

http://web.archive.org/web/20000919074447/http://www.icst.com/pdf/9169c-27.pdf

( http://uloz.to/xL5L3QiW/ics-9169-pdf )

I simply introduced my own clock to the PS/2 controller Holtek HT6542b, as it supports:

http://www.alldatasheet.com/datasheet-pdf/pdf/64463/HOLTEK/HT6542B.html

...because that way it is not tied up to the FSB clock = mouse and keyboard works fine at 7.14MHz

How fast (_really_!!!) are the clock (watches)? I want a video with seconds windows near real watches If all is correct - you are the best!

Sure the clock is correct and I can prove that to you very easily As you suggest - real clock + video. Could be done, if you did not see how I did it. The PLL chip ICS 9196 support the REF / 2 (FSB = reference clock (~14MHz) / 2) as you can see from the documentation.

So, there you have it. And I seen 2MHz clock for CPU and there is a possibility on validation... but it will be tough

Albeit no, you're the best in any case )

Well, to convince you, there are problems, what S3 Trio3D have with 3.75MHz PCI bus:

So it is not that easy. There you have a video from it:

So it was not all peachy and easy... ))

I think I give up... I tried lots of stuff. 486 is not validable. CPU-z works on Windows 2K - big thanks to RomanLV for idea!

I told you so, Win2k is fine.

I have funny little Socket4 mobo. It's "Intel Batman's Reveange" LOL. Please take a look at it: LINK http://abload.de/img/adrklq.jpg. Sadly the BIOS was corrupted and I tried everything!!! Here is a photo what I had to do because of clock is ticking and I had no PLCC socket

Crazy. Nice try, tough. Can you match 7.14MHz...? Or 2MHz? That would be a challenge and I know I can do it

PS. as expected, the K5 PR75 @ 90MHz crashed on the end:

...witch makes me wonder, if I go the right direction. To put long story short, I stabilized P90 @ up to 125MHz (more this board did not manage) for SuperPi 32M with PCI latency bump from default 32 to 42.

So on AMD K5 PR75 I reacted similary, bumping the latency up and up... This crash was at 96, so I set 102... and even floppy drive have problems now. That got me thinking, if I did not do it entierly wrongly, so I try default 32 with the CF card and we see

...

So I used the pause to check on the memory usage: 23.5MB it is:

What do you say, ludek? And there is still possibility to shave some kBy... and I believe that the last running service is not need anyway, so... there is room for optimizing

ludek -

I crapped the Batman's Reveange. Mobo was struggling to take me away from setup.

Very sorry to hear that. The work and attempts you put into this... stunning! And sad... Maybe you could get back to it one day - get a proper socket, flash the bios in other mobo and plug it back there and give it a try? I use BIOS Saviour for that. But I'm kinda surprised that such old mobo use such modern bios chip... My TXP4-X use the old, big bios chip... your one looks much more modern.

What else this mobo have in sleeve?

...witch makes me wonder, if I go the right direction.

Please use contact-cleaner to MEMS and maybe vCORE mod. Take a look at my AMD PR75 score. I used 4.5 V and TEC cooling. It made system ultra stable.

But... on the very same mobo I made this score: http://hwbot.org/submission/2978646_

So if the rams/mobo works fine at 83x1.5 P90, then why it should not work at 60x1.5 K5 PR75? We know, that the mobo and the overclock of the K5 PR75 is stable, because if it is not, then it will not made this score: http://hwbot.org/submission/2986787_

So I'm all for cleaning the contacts of my AMD K5 PR75 CPU, but it would be better if I can set the HDD right to use DMA in the first place. That would be much better start

Of course a Vcore mod will be great. The mobo gives top 3.4V, witch I use. If I can get that to 3.6V, I have no doubt the AMD K5 PR75 will run at 99MHz (66x1.5). I already seen it almost finish the post at such settings... The mobo is mainly targeted for downclocking anyway, so there is not much need for excesive voltages Sure, 4.5V + TEC cooling easily "convince" any CPU for some overclock, yes

But mine P90 run on ALL the FSB settings the mobo give - 7.14 - 50 - 55 - 60 - 66 - 75 - 83MHz

So memory contacts are innocent there.

there is still possibility to shave some kBy... and I believe that the last running service is not need anyway, so... there is room for optimizing

damn you're good It that 16bit desktop?

Yep, WinXP did not allow 256colors. 16 or 32bit only (on some cards 24bit as well or - worser - only).

Using NVIDIA GF4/5 cards I seen less ram usage when 32bit colour set.

Could be a bug in their drivers, as 16bit framebuffer obviously consume half of the memory for 32bit one. But I could try it...

Which services you left working?

I told you, only ONE service is left running IIRC it is Remote Procedure Call (RPC). And that one could be disabled anyway... but to operate the services I must first start the Plug&Pray service Also I must manually end the userint process that is on when WinXP starts and later exit automatically...

But 23.5MB of used ram is worth it, is not it?

I always left 8 (Plug and play, 2 Hard disk services, event log, hid, task skedule and 2 or 3 "important" services) (or nine?)

Yea, the Windows claim they are need, but they are not need in reality. That is like claiming that WFP is need. Of course it is not. And I'm much more proud on my work on the WinNT optimizing. I think that there is chance to get them under 10MB with 800 x 600 x 256colors screen WinNT are very tolerant. They - for example - use a little bit less ram and allow deleting the bmp screen logo, that are in background when you login. I really like system that can be tweaked to such extremes ))

Only one question remain - will wPrime finally work on it, once I get it to be SP3...?

But wait. If you turn ON pagefile, the amount of memory is incorrect. Turn off the pagefile and then tell me the numbers

Yes, page file is on But it will be IMHO even lower, when I turn it off... )))

ludek - so I made todays some memory info screens for you on WinNT, installed on the new shiny AMD K6-III+ CPU: http://valid.x86.fr/ljdyc2

(yes, that board can run FAST too It run like a wind with the 500MHz K3 with even L3 in use )

As you can see, a 9592k of memory usage with pagefile, 9580k memory usage w/o pagefile

(there is still some optimaliztion that can be done, but it won't be much, I would say 0.5MB at the very best case, if I manage to change the properties of the last memory hungry service from the two ones left? HWbot competition on how overclockers can optimize their Win down to smallest memory usage will be fun )

Are you sure you want to repeat that for the WinXP? :D ...because I'm going for SuperPi 32M, so you have time to think about it

Yup, I use BIOS Saviour when I need. Hot-swap bios chip is doable and I did it plenty of times, but this one make your life much easier. Good luck with your mobo

And yes, 9.5MB memory usage is not bad. But... what about 9.3MB usage BUT with 1024x768?

That translate to possibility of nearing 8MB of memory usage in 800x600. Remember, if I disable swap, the memory usage will be actually lower. And there is STILL optimalizations to be done! I'm not finished, no matter how crazy that might sound. WinNT rulez
