"I have been successful in getting the k6-2/266 up and running on my PA-2007.  

My System: 
FIC PA-2007 rev 1.2 
Beta Bios 113cd135 cpu is identified as K6-2 
128mb (2x64) SDRAM (Hyundai) 
rem: I use fastest possible timings and 4-bank interleave 
Standard Heatsink and Fan 
cpu used is amd k6-2 266 2.2v 
Clock generator on Board: W48C67-01H 1734T 
Chipset used is VT82C590 Apollo VP2  (595_9737CD+586A_9727CD) 
 

First i tried the standard 4x66 at 2.1v.  It ran perfectly,  but couldn't satisfy my appetite for speed in Unreal.  Then i went on to 4.5x66 at 2.1v.  Amazingly it ran rock solid.  This is my standard setting now. 
I cannot approve that it works with any of the 75mhz settings because unfortunately my Sdram is not able to keep up (i think).  I also encountered this problem with my 166mmx p5, so it's not k6-2 specific.  The whole thing worked also with 5x66 at 2.1v but,  i had a few shell32.dll and kernel32.dll errors in win98,  so i tried 2.3v and it was stable until,  well... until my win98 blew up with a registry error that couldn't be fixed without a complete reinstall (it halted at startup).  I suspect,  although i am not completely sure,  that it was caused by overclocking.  I went back to 300/66 but changed the voltage to 2.2v as described on your page.  This Machine is running very fast now and best of all - rock solid. In five days of extensive (i mean it - 15 hours a day!) use i encountered not one crash or any strange behavior.  Lately i downloaded the optimized Q2 minigl from AMD and it rocks.  I want to give you some Benchmarks, too 

If you are interested in more details,  I will be glad to give you more information to contribute to your page - It is the main reason that now I have pentium2-like performance and saved at least half my money.  By the way,  please excuse my terrible language - i am a german who knows english only from surfing the internet and playing silly computer games. 

See you 

Alexander"

Why does my VIA chipset-based motherboard crash under Windows98? 

This problem is caused by incorrect assignment of IRQ by Microsoft Windows98. MiniPort driver released by VIA reassigns these IRQs. The driver has not been released by FIC yet but it can be found on the FIC FTP server. 
  
For more information,  check out the VIA chipset FAQ at VIA's Taiwan web site. 

I also have a brief report from one daring pioneer venturing to try the 5.5x multiplier with his K6 266 processor: 

"I am running 333MHz using 5x (1-2, 2-3, 2-3) since a couple of weeks very stable at 2.1 V,  I did try the 5.5x setting (1-2, 1-2, 2-3).  It did not POST at 2.1V but did at 2.4V and displayed 366MHz.  I have a 266 chip and I am not feeling comfortable running it at 366 and 2.4 V,  I would do it at 2.2V though."

PC100 SDRAM 
The results so far,  from users who have successfully used the following PC100 SDRAM in the PA-2007 motherboard: 

PC100 SDRAM is pure overkill for your PA-2007 motherboard but it will be a requirement for your next motherboard.  I have planned to upgrade the memory in my system and go for PC100 SDRAM to try and future proof my investment.  Now, in the future when I move up to a Super Socket 7 board I will already have the necessary PC100 SDRAM.  Currently I have no information on which PC100 SDRAM works with the PA-2007.  Can anyone make any recommendations or have any experiences? 
  
  
  

I have received a reponse from FIC regarding the BIOS S.M.A.R.T. capability: 

     'You can get answer in this page. 
     http://www.seagate.com/support/disc/faq/smart.shtml 
     Harddisk must support this feature then you can enable it.' 

I guess I will read this page again to find out how to use the S.M.A.R.T. feature.   
  
 
 

I am searching for a list of S.M.A.R.T. enabled hard disks and I will let you know what I find. 

I know FIC Technical Support could shed some light on the subject.  I will post  their response.

Now it seems FIC did not lock bios @ 66-68.5 
This system runs great at 68.5 or 75mhz---rock solid 
However my chip will not run @ 333,337.8 
Not one lock, crash etc. with the 1.13cd135 bios---no problems! 
This is the bios for anybody who had warm boot looping problems with 
the PA2007 and k6-2. 
Thanks Antonio and Mike Rains  
Looking forward to reading all the k6-2 PA2007 posts

Today I bought a K6/2-300 and it runs fine with Bios 113CD13 at 2,1V. 
I don't have this rebooting problem. 
My System: 
FIC PA2007 Rev.1.2 
Bios 113CD13 
10ns 64 Mb SDRAM 
Elsa Victory Erazor video card 
Symbios Logic 8150S SCSI Controller 
IBM DCAS 34330U 
Teac CD-516S  
MOD Fujitsu 2513A2 
Soundblaster AWE64 Value 
Elsa Microlink 28.8 TQV modem 

Here are some Wintune98 results: 
clock rate 301 MHz 
Dhrystone 774 mips 
Whetstone 348 mflops 
CPU load 4% 
mem read 530 mb/s 
mem write 585 mb/s 
mem copy 310 mb/s 
overall mem 475 mb/s 

This weekend I will try it with 333MHz. I will send you a message if it runs fine. 
 

I have sent the beta BIOS, 113cd135, out and hope to hear from some more happy K6-2 owners.  The BIOS was posted to me by Mike Rains.  
 
 
 

I have updated the PA-2007 FAQ in response to information you requested. 

I have yet to start on the BIOS flashing report. ETA unknown at this stage.  Do you have any suggestions for the BIOS report? 
 
 
 

Dear Sir 
I'm using the PA2007 and the k6-2 266 overclocked to 300mhz. 
Also I'm running 68.5 4.5x 2.3v and its running great! The one problem 
I have is when I warm boot i.e. ctrl alt del, it throws it into a rebooting 
loop right past mem check. My bios is 113cd13.awd via chipset vt82c586a, and 
ICW w48c67- 01h-0703  1731t. My board is pa2007 rev 1.2. Also is this 
ICW chip locked @ 66-68.5 or can I try 75mhz? Is this the right bios for 
this chipset-board? It seems many people cant get this board to run this k6-2 
because of the rebooting looping problem! Outside of this one problem my 
system runs great!  So close to perfect! 
Thank you 
Regards

There is some bad news with this update.  I still have a report of the looping reboot problem stills persisting even after the new 113cd13 update. 
 

BTW,  the FIC gods are watching over the PA-2007 Technical Reference site.  It seems they have updated the FIC PA-2007 FAQ on the Taiwan site with a link to my innovative user front page.  Cool, hah?  

I pray to the gods for continued PA-2007 motherboard support,  an FIC approved re-engineering core voltage kit (included one 100K ohm resistor = 2.2V),  and definitely continue producing kick-ass products! 
 
 
 

Furthermore,  it seems flashing back to 109cd12 fixes the problem.  Ah,  it seems to be a BIOS problem.  Those of you with this problem have you tried the more recent beta BIOS 113cd15?  I will keep you all updated. 
 
 
 

So today before you leave this site check out the discussions.  
 
 
 

I am curious to know more details.  What speed and cpu exactly does the beta 113cd133 BIOS report?  I guess we must give Smoker and his son some time to test the combination.  How rock solid is it?

WOW!  I never thought I would see the day, but it has happened.  What you ask?  I'm talking about PA-2007 core voltage adapter envy.  Visiting a number of message boards at various hardware sites all I see are posts claiming undocumented and unproven core voltage hacks on various other motherboards.  I'm not flaming the people who post but lets see some proof  -  how and why it works.  Remember make sure you don't try any unsubstantiated voltage settings or else something will fry! 

The voltage settings I discovered were tested and proven and then confirmed by FIC Technical Support but please note they do not endorse it. 

I will explain how the 100K resistor jumpered at VR position 11-12 on the PA-2007 motherboard gives you 2.2V.  FIC has confirmed the following resistors values that determine the core voltage settings on a revision 1.2 board: 

The newest BIOS file I have for the PA-2007 motherboard is beta BIOS version 113cd15.  I have not used this flash file on my board yet but WindWalker author of the PC Hardware Blue Book site has and reported a small performance improvement with his system but his BIOS still displays BIOS version 113cd133. Go figure.  What does it mean? 

FIC have posted new memory support documentation for the PA-2007.  It documents the 64 MB and 128 MB tested with beta BIOS revision 113cd133.  The report is available on Your Page.

I have added a new page, 'Your Page', devoted to the valuable information I get from your e-mails and the information I find in newsgroups.  So enjoy!   
 
 
 

Sorry to the owners of the PA-2012 motherboard.  I do not have a PA-2012 motherboard which I can do my core voltage testing with.  Therefore I cannot help you with a 2.2V setting.
