Confused about the CPU situation. What to buy, Athlon with or without 133 FSB?

Hi,

Then the CPU drops again ? the 5th of March right? ? I will move my fat but down to my favourite computer store and buy me an Iwill KK266 motherboard and hopefully a lot of high-speed RAM (mushkin or corsair). But here is what troubles me: I don?t know which CPU I should buy! I?m looking forward to play around with the FSB, but should I buy a 1 gHz with 133 FSB or with 100 mHz? Or could I just buy a 750 mHz Athlon and then raise the FSB to 133, so I would run 1000 mHz?
As you can hear, I am very confused :confused: ? thanks in advance.

I'm not thinking of buying an Athlon 1200 MHz - so this wont be a problem... Still VERY confused, but thanks.

This is from GamePC:


<< 266 MHz FSB - No Go.
We had some issues getting this board to work at 266 FSB speed, and apparently it looks like some sort of problem between the IWill KK266's BIOS and factory unlocked chips. The thing is, every 1.2 GHz Athlon we've seen hit the market thus far has been factory unlocked. 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.

So what does this mean? If you've got a 1.2 GHz Thunderbird, you may have issues going to 266 MHz FSB on this board. IWill tech support said others have already complained about this problem, and they believe it's a problem with AMD's 1.2 GHz factory unlocked chip. To be fair, we've also had this problem with MSI's new K7T-Turbo R motherboard, which uses the same BIOS, but on the other hand, we haven't had this issue with Abit KT7A and Asus A7V133 boards using these same processors.

This means unfortunately we could not run 266-MHz FSB benchmarks on this motherboard, since the 1.2 GHz chip we have in our labs is factory unlocked. We've still included benchmarks at 200 MHz FSB, which performed surprisingly well.

I didnt really pay attention to the chip he was looking into, but heres a blurb from the article about running it at least with a 1.2 ghz chip.

ok i saw that.. but if i understand the article correctly, the reason they couldn't get it to run at 266 fsb is because the 'unlocked' 1.2 ghz they were using wasn't an athlon-c. so it's not a fault of the motherboard, more the fault of the review. note at the end it references to the &quot;official&quot; amd 266 fsb t-birds (athlon-c) i'm pretty sure what they meant is that their 200 fsb athlon woulnd't run at 266 fsb for the review.. but the official chips will have no trouble.

at least this is what i think is going on...

petes your totally right. I just didnt pay attention to the chip he was looking into and i had rememberd reading this review and the problem they had overclocking.

flue,

I'm in the same predicament. I've been scouring reviews to find someone overclocking an T-bird &quot;C&quot;. So far I haven't found one but I'm still looking.

If I find something out I'll let you know either with a pm or here on this thread. I've read about a lot of good luck getting 700's and 800's to go far. One thing you can do is search the &quot;for sale/trade&quot; thread and look up user messages for compuwiz1. He doesn't have time to answer questions but he sells lots of o'clocked chips and it'll give you and idea of what can be achieved. I believe he uses a FOP 32-1 to test his chips and he guarantees them all.

Read a couple of those threads and you'll get a decent idea of what you can expect.

Good Luck

OK, you guys are talking about the same thing I have questions on. It doesn't seems as though anyone has a lot to say about overclocking the Athlon 'C' chips - but that's exactly what i plan to do. Good catch on the difference with the chips - specially since I already have my Iwillkk266 mobo and I'm just waiting on the 1.2 Atlon c chip. It was throwing me off with the 266FSB problem but you are right - they were using the 200 mhz chip factory unlocked. Think I will surely test everything at default first.

Saw one guy in the Amdzone forum has his 1.13Ghz 266 cpu up to 169 FSB on his Iwill KK266. Its only one guy to start jump to conclusion, but so far the 266fsb chip seems to have a higher FSB capablity.
