I DEMAND EXPLANATIONS!!!

[Guest]

It's beter to say I need some answers....people here say that if I put 1.2Ghz 266fsb tbird on A7V it will detect it as 750Mhz (133x7.5?), then why other people suggest to do that? it is HIGH underclocking! and changing multiple from 7.5 to 12.0(and setting bus to a 100Mhz) I should consider as overclocking? and can can CPU fry if I o'clock FSB way to high and it will work?

Manarch, you're starting to tick me off. If you'd just calm down and post serious subjects, people would look at you a lot more agreeably.

Apple? Macintosh? What are these strange words you speak?

Not sure of your question. If your FSB is 100mhz and your multiplier is 12, guess what?? Your cpu will be at 1200mhz. Your memory can be operating at 133mhz on the A7V but your FSB will be 100. So you buy a 'C' T-Bird 1200, stick it into your mobo, 100mhz fsb, change multiplier to 12 (A7V has a multiplier 12 setting) presto, 1200mhz. Overclock by upping the FSB, at 110mhz your cpu will be at 1320mhz, while your memory would be bumped up to 143mhz unless you change the memory speed to 100mhz. KT133 didn't go reliably past 115mhz for most people. Don't worry about the default setting, the 'C' T-Bird default multiplier is based on a 133mhz fsb, you don't have a 133mhz fsb, you have a 100mhz fsb which means you have to adjust the cpu multiplier (via bios) to get the T-Bird up to rated speed. Comprenda??

I give up on him!

Good or Bad have no meaning at all, depends on what your point of view is.

NO...I made a stupid mistake, 133x7.5=1000Mhz..sorry.
Here is how I think:
1000Mhz tbird 266fsb officially made for KT133A chipset with 133Mhz fsb, right? (well and other mobos that support 133Mhz fsb), so multiplier should be set to 7.5 and bus to 133Mhz.
If I'd put 1Ghz tbird "c" on my mobo then the fsb would be 100Mhz(downclocking) and the muliplier set to 7.5, I'd have to change the multiplier to 10, but 1Ghz Athlon "C" was MENT to have 7.5 multiplier and raising it to 10 would be like o'clocking. This is the way I think. So why would it work fine with 10?

Overclocking really depends more on the final speed of the cpu vice the multiplier or the frequency of the FSB. In other words I can overclock two ways (<font color=red>two factors</font color=red>), the <font color=blue>multiplier</font color=blue> and <font color=purple>FSB</font color=purple>. Since the A7V is a 100 FSB, putting a 'C' T-Bird into it will underclock the CPU by the FSB design of 133mhz to 100mhz (<font color=red>100fsb x 7.5cpu = 750mhz</font color=red>). So to get the cpu back to rated speed you have to raise the multiplier to 12. Once you do that, you still havn't overclocked the cpu because it will be running at rated speed of 1200mhz. <b>Only when you raise the cpu over its rated speed is it considered overclocking</b>.

Another way of looking at it is that the FSB is underclocking the CPU below 1200mhz, so you compensate by raising the multiplier so that the cpu is running at rated speed of 1200mhz. Bottom line, if the cpu is running at 1200mhz it is at rated speed, at below 1200mhz it is being underclocked (regardless of FSB or multipier settings), if above 1200 mhz it is overclocked (regardless of FSB or multiplier settings).
