Iwill KK266 and 266 CPU's

[burat]

GamePC has a review out today stating a problem (also seen reportedly with MSI's K7T Turbo)using factory-unlocked 266FSB T'Birds. What's up wit' dat?

As they said "When using a factory locked chip, we didn't have any problems lowering the multiplier and running up to 266 FSB. With the factory unlocked 1.2 GHz T-Bird, we would tone down the multiplier (which works), but once the FSB was cranked up to 266 MHz, the board would not POST."

Maybe a BIOS problem? I'm pretty sure there are some owners of this combo in this forum that don't seem to have this problem.

ya i was wondering the same thing. is that only effective with the 1.2g or the 1 and 1.1 as well? running at 266 of course

I THINK this quote will clear things up from the end of the article...

Perhaps that problem can be fixed with a BIOS update. Let's just hope the problem isn't still around when AMD's "official" 266-MHz FSB chips hit the market.

In other words, I believe they were testing with 200FSB chips. This is the same problem that has been discussed quite extensively on this forum with 1.x GHz Tbirds. At this point, I think the solution is to:

1) initially keep all BIOS options at default, lower the multiplier down to 6 or 6.5, and then reboot. From there, it is my understanding that the board can handle these Tbirds.
2) if this doesn't work, modification of the L6 bridges appears to fix the problem.

Someone PLEASE correct me if I'm wrong...

I just thought that by using the 266's, that we could avoid these annoying glitches(?). I thought that with the Athlon-C's, you'd just pop 'em in, and away you go; I guess that's wishful thinking. I was hoping to avoid fumbling around with the L1 / L6 bridges.

I think the problem was only with the 200 fsb athons. I believe the new 266(c) athlons will work fine.

My fault; I obviously misread the article (that's what you get when you skim through an article quickly, when you should be doing your freakin' work).

also important to note: the review is dated february 28th, which means the tests probably weren't done with the new bios update, which is date stamped february 27th and announced on iwill's just today (i think). the new bios my fix the 'out-of-spec' 266 bus issues.

going home to play with my kk266 today. i took it with me to work this morning to stare at it, drool over the manual and settings, and generally show it off.

Keep us posted - puleeez!!!

Yep, the kk266 has problems with the unlocked 1.2 gig tbirds. Mine would not boot at 266 mhz no matter what I tried and the BIOS update did not fix the problem. The board tries to read the initial multiplier and FSB so it tries to boot at 133X12 even with the multiplier set lower in the BIOS. However, I have an A7V133 that works fine at 147 mhz FSB, so save yourself some headaches and do not get the kk266 with a 1.2 gig 200 mhz tbird.

has there been any problems with any other cpus other than the 1.2 athlon?

 

[IntelConvert]

There shouldn't be any such problem with the new 1.2Gig 266Mhz FSB CPU, and seeing that the new C-part is becoming available, why not?

I have this combo (200 fsb 1.2 Gig Tbird/KK266)..it has worked flawlessly for me: I did exactly as Nelmster suggested..first running at lowered fsb with 100 fsb - then jumpered for 133.

I can change the fsb & multiplier any way I wish - It'll only do 1.4.

I just spent over 4 frikkin hours changing my mobo and CPU to a new KK266 and Factory unlocked 1.2 T-Bird. I could NOT get it to even boot to a BIOS screen!!! I tried every trick in the book, and finally caved in and put mu old crap back in

How did audscott get his to work?
