got the kt7a-raid board version 1.0 and it has a thunderbird 1400 cpu in it.

i got a 2500xp barton cpu and was wondering would this board take the barton cpu? i know barton is 166fsb and the board is only for 133fsb cpus but i don;t mind running the barton underclocked since the main reason for the swap is for a cooler running cpu in the machine.
barton 2500 multi is 11x so at 133fsb it shoudl go to 1460mhz so hopefully i can undervolt it at that and being barton it should be faster clock for clock than thunderbird, not forgetting the extra cache on barton.

main question is though, can the board i have work with the barton cpu?
 
Official answer. <that's Abit.

I can't remember myself, and all the old threads have gone from here :(

There was also a site called "Paul's Unofficial ABIT KT7 FAQ", but that's gone as well :(

The real old school answer is "try it and see" ;)
 
yeah try it, at college there is a PC with a KT133 chipset so its older than your KT133a and it took an XP2400 underclocked (112FSB max) it worked fine...and here I have a GA7ZXE motherboard that has a KT133A chipset that works with a Sempron 2500+ @ 150FSB so it will most likely work.
 
well im shocked, i put the barton xp2500+ into the board and its posted. set the speed in bios to 11x multi and 133 fsb for 1466mhz and now its booted up into windows. :eek:

iv got it at 1.60v in bios, guess i will stress test it and keep lowering the vcore to get it running as cool as possible.
 
vcore sitting at 1.55 and everything is stable. proper shocked at this old board. still does not cease to amaze.

temps have dropped 11c over the thunderbird 1.4ghz cpu which ran using 1.75v. shocking to say the least, i think the barton can actually go even lower a notch or 2 on the vcore still. it is afterall running around 360mhz lower than stock.
 
The barton could probably do stock speed at 1.55v, so you may even enter the 1.3v region at 1.46Ghz. Yea those KT7s were impressive, had one that took cpus from 800MHz T Bird to palominos to the 2400+ mobile Barton when i finally retired it to the loft.
 
hmm, guess that i will give the vcore another drop later on and see how things go.

currently set at 1.50v in bios and it shows up as 1.54/1.55v *bit of an over volt) so hopefully can go a bit lower.
very happy with the temps so far.
 
I've got a KG7-RAID and pulled it's Thunderbird 1400 when I had a spare Barton 2500+ come my way and it works fine. I can check the multi and Vcore settings I used on Monday if you want.
 
cool, im gonna be trying to go lower on vcore tomorrow, very happy with the old system now, its snappier on response, guess the bartons 512k cache is kicking in well since the memory subsystem in the system is slow being Single datarate ram (SDR).

Yes, great boards indeed ! I used to have one which I gave to my brother more than 3 yrs ago. He runs it 24/7 under full load, and it's still going strong ! The northbridge fan is on it's last legs and needs replacing, but apart from that it's fine. It must be 5yrs+ old now. It runs an XP2000+ Palomino.
 
same here, my board is used as a server machine too. i replaced the northbridge fan with the big blue zalman passive heatsink. no noise and probably better cooing than the tiny heatsink and fan that came as stock.
i remember when i changed the northbridge cooler i was having stability problems at 133fsb with the stock northbridge cooler, put the zalman in and though hey may as well give it a go and boom ,133fsb stable. happy with the system now with its thermaltake silent boost heatsink on it.

Yes interesting - his runs at 130FSB in fact, because at 133 for some reason it locks up running memtest after a while. Never got to the bottom of it (board or memory), but it's been running for years now at 130 and it doesn't make a lot of difference in performance

mine took some heroic abuse (166hmz fsb @ 3.8v vio for suicides 157fsb @ 3.7 vio for 24/7 O.o)

Heh, i had one that i touched by mistake with a screwdriver with it on, something smoked and since that day it ran 4.1v I/O :D Got me 160MHz stable for roughly 8 months and then it had enough and choked, i think the RAM and T Bird still live to this day!
