Abit KT7 vs. KT7A with Standard Thunderbird

Hey all!
Been awhile! Hope everything is going smurfy around here.

I've got a question here.
I've tried clocking the FSB of my Thunderbird to 133MHz on a KT7 Board (VIA KT133 chipset). Now, I can't post beyong 112 and the system isn't stable unless it's around 105. As I understand it, the real dilemma with the overclocking isn't the CPU at all but the way the KT133 was designed.
Is this true?

My question is: If I were to purchase an ABIT KT7A (VIA KT133A chipset)that natively supports 133MHz FSB, would I have no troubles overclocking the FSB of my current CPU (standard T-Bird rated at 100 FSB all DDR of course) to 133MHz? (My RAM is Crucial PC133 Cas2. 256 MB unbuffered.)

Thanks all!

    Simly said - you wouuld have troubles. So dont spend yer money. The mobo was designed for TB-C series (133mhz FSB), not a regular one with 100mhz FSB.


    K7 + KT7A + MX300 + VooDoo3000 = :smile:
    P3 + CUSL2-C + MX300 + Asus7700 = :smile:
  2. I have a KT7A mobo running a 1.1Ghz (11*100 stock) at 1.2 (9*133) with no problems. The voltage is at 1.75 w/ same memory as you (crucial cl2 256Mb Pc133). If you look at some of the previous post there are a number of people who have asked similar questons to you and numerous people have run b version athlons as c versions w/ no problems. You will have to unlock the multiplierand lower it so that the CPU is not running way over specified because it wont boot. ie if you have a 1.2ghz (12*100) and you want a 133Mhz bus you will need (9*133) for it to run at 1.2Ghz. If the system is stable at this then the mult can be increased.

    Much appreciated.
