Will the ABIT KT7 board run a 1GHz 266 Tbird?

I'm having problems getting this chip to run upto its specs. I was wondering if this board does not have a 133/33 setting. The only 133 setting I can use is 133/44 and I can't seem to get a boot out of the system. If I take it back down to 100/33 I can get a post, but then I'm at 750MHz. What gives? any help would be appreciated.
 
Unlock the chip and change the multiplier to 10x, and leave the FSB at 100. You won't get the FSB on the KT7 over 110 guaranteed!! At least not for more than a few minutes..
 
Thats what I was afraid off...I guess I will unlock this sucker...where should I go to find out how to unlock this puppy....I know I have to use the pencil trick..just haven't done it before...I've always bought AXIA chips before.
 
check here. I found the loctite defogger kit the easiest to use. you will need a eye loop, scotch tape, razor blade and a toothpic. its easy don't sweat it.
 
If you decided to just pencil the L1s just use a mechanical pencil to connect all the L1 bridges and make certain they don't touch each other. As to using it in the KT7 I've put a 1.4T-Bird(266fsb) in for sh*ts and giggles and was able to run it@112x12.5=1400 although Sandra said the FSB was 108mhzx2 and I've read that the bios does misreport the FSB on the KT7. Anyways, I would try it@12x100 or 11.5x105 and if it is stable keep tweaking it upwards. You could if you have a good overclocking 1ghz CPU see 12.5x105 or even 12.5x110 on that board. Good luck and fun 🙂
 
I've got a 1GHZ AXIA on my setup unlocked. It will run @1300mhz (Sandra and Bios reporting) all day long using 12.5X multiplier. The bios automatically changes the FSB to 104 when I select 12.5 multiplier. Don't know why bios changes it automatically, but it runs smooth there. I haven't tried many other combo's, just because I know ther KT7 is a poor FSB OC'er.
 
I suggest u use the pencil trick if u r inexperience in unlocking the CPU. Any mistake...just use an eraser & erase the marks. Using pencil is not lasting...but less risk of messing up the CPU. Btw, the pencil trick will last for around 2 yrs.

Oh yeah...this mobo support 1Ghz @ 266 FSB fine. Update to latest bios to be safe.
 
Hi!

JustStarting: check your bios version, I remember reading in Paul's FAQ that some bioses do not detect properly unlocked high speed Athlons. You could try refreshing the Bios to 64.

But if you do not have problems, don't give a s*it about it 🙂

To unlock the chip I soldered the bridges (once on a Duron and now on the Athlon). So if you have some little experience in electronics then you could try that 😉 I hate repenciling once in a while...

Cheers,
 
If it is a KT7 then I would, as stated earlier, forget about going very far past 100 for an FSB. However if it is a KT7a, then that bad boy can get quite close to 150 or higher if you put a more aggressive HSF on the north bridge.

In respect to unlocking the tbird/spitfire CPUs, I have done the pencil trick for a good number of people as well as myself. It works almost all of the time. What I found out it won't work on is the L7 bridges (default Vcore). What I did, and I think I have seen it on a couple of sites, is to use a rear window defogger repair kit. I got one at Canadian Tire for $10 Canadian. It has a small bottle of what amounts to very conductive paint. Although there are a lot of places that suggest to use a tape mask to avoid unwanted connections, I found that all you need is a very sharp pin from a sewing kit or a safety pin. You dip the tip into the repair fluid and when you touch the cut in the bridge, capilary action will suck it into the gap and unlock the bridge. I do recommend having a magnifying glass to do this with and if you are not steady of hand it would be a good idea to use the tape to cover the other bridges. The only thing about using tape is that you will need to wait a while to let it dry well. Otherwise you will end up just peeling your work off with the tape.

Good luck and have fun🙂🙂🙂

I have arrived....I did the pencil trick flawlessly last night. I know have the 1GHz Tbird running at 1.2GHz at default voltage. Thanks guys....
 
A tip for anybody updating to the latest "64" BIOS - DO NOT FOLLOW any of the ABIT site instructions. Or the the instruction given at the other "Pauls KT7/KTA FAQ" site - they are both incorrect - well thats how it worked out for me on Saturday night while updating my "WW" BIOS to "64" BIOS.

I spent ages trying to follow their instructions - each time the BIOS would not install 🙁

All you do is copy KT764.exe onto the formatted BIOS disk - then run "KT764.exe" in DOS and follow the onscreen instructions.

It took me 2 hours to do a 2 minute job 😕

This is not how it is described by the two sites....maybe I was confused - it was 1:30am 😉
