2500+ Barton DOES work with my KT266/A Epox 8KHA+ MB 11X166 (Update - Now 12.5X166 for 2800+)

Greetings all,

I wanted to let you guys know that I just received my 2500+ Barton from Newegg.com (Retail) (AXDA2500DKV4D Y867217250834 AQXEA0329XPMW) and it is working excellent with my Epox 8KHA+ KT266/A revision 2.0 motherboard. So, if you are like me and don't want to spend the money to upgrade your motherboard (actually for me it was the hastle and not the money) and you have a KT266/A MB then there may be hope for you. I am running Crucial PC2100 memory and my settings are 11X166. I have not tried anything higher at the moment. I have run several PCMark test and 3DMark03 test and everything looks good. I have it at default voltage and default memory speeds. The 2500+ is a week 29. My temps during a full load have been only 45 - 48C. I am using a Radeon 9500 with the Softmod to open up the 8 pipelines (so it rus as a 9700). I recently flashed my BIOS with the latest from Epox. I believe Epox offically states that they do not support the Barton with this board, but I am here to tell you that it works. Let me know if you want any other information.

Take care,


Update* I have changed the multiplier to 12.5 and I am running at 166Mhz with turbo settings on my ram. This amounts to a 2800+. Everything is extreamly stable and running fast. Let me know if you have any questions.
 
Of course it works if the FSB can handle 166... (166x2 ) 333FSB...

It's like saying some boards don't support the 400 FSB XP's, but if you can run 200 mhz FSB then you UNOFFICALLY can...

Glad it worked for you.
 
I have an Epox 8KHA+ running an 1800+. How can I tell if I have the rev. 2 MB? This seems like a viable method for a cheap upgrade...

Sandra might be able to tell you...

CPU-Z might also have some chipset info...
 
First off, let me start by saying that I heard that all Epox KT266/A motherboards are rev. 2.0 and the ones that say 1.3 were misprinted. I believe this is because the 8KHA [non (+) Plus] board previous to this one was a KT266 that was at rev. 1.3 so some of the early 8KHA+ boards had 1.3 printed on them when they changed the northbride and made it a Plus.

I am not sure if I believe that because if you look at the recomended processor list from Epox, it breaks rev. 1.3 and rev. 2.0 appart.

With all that being said. You can find out what revision your board is by looking at the corner of the motherboard where the PCI Cards are located. It will be printed on the very corner.

Let me know if anyone has any other questions.

Take Care,
 
Cool, I checked and mine is 2.0 🙂

So my next question is: By running the front-side bus at 166 on this board, are you running the AGP/PCI/IDE devices out of spec? Could you detail some of the BIOS settings you used to set up the 2500+ successfully? Thanks a lot for your help!
 
Yes, I am running everything out of spec. I am using the 12.5 multiplier with 166Mhz bus (equivalent to 2800+). The 2500+ Barton came unlocked, so I did not have to do anything with that. I am running Turbo settings on my ram which is Crucial PC2100. The only thing I had to do to get the 2500+ Barton to work was to flash my board with the latest bios and change my multiplier and bus speed.

Good Luck,
 
Can I ask what cooling you're using? I've got an Alpha 8045 with a PC Power & Cooling low-noise fan and thinking I might need a louder/faster fan for this setup...
 
Hmm, I'll check mine tonight. Mine is running a 1600+ still with pc2100 memory, and it just seems sooooo slow compared to my nf7-s/barton/3200 memory machine. glad it worked for you though, maybe I'll do that when the prices drop even more on the 2500's.
 
heh that's nothing i had my 2400+ working on my kt133 at 2.53ghz
just a matter of making it work.........

you've got a good system there
gotta love the socket A longevity

i use a pal8045 as well. What i did was get an 80mm>90mm fan adaptor and stuck a 90mm panaflo L1A onto the heastink. It offers 42cfm at 28 decibels which is nice and quiet for the air it delivers.
 
I just got a $20 heatsink and fan from CompUSA. I don?t know what model it is but it has an 80mm fan on it and it was the silver plated copper heatsink. It was kind of loud, so I got a $6 dial fan switch (also from CompUSA) and turned the speed of the fan down until I was getting acceptable temperatures and noise. I am currently running the fan at 3000 RPM and my temps under full load are 50C, which I hear is acceptable.

You can download a program on the Epox website that shows the temperature of your CPU and the speed of the fans, if you connect the fans to the motherboard.

Hope this helps.

Take care,
 
KT266A running at 166Mhz bus??

Hell this is not just any KT266A, this is the best KT266A that ever was, probably better than many KT400 boards. That is Epox 8KHA+. Damn I feel sorry I sold mine, that was a rocket. :brokenheart:
