133Mhz FSB T-Birds

[AndyAkins]

Are the 133Mhz FSB T-Birds available yet? I'm not talking about overclocking a 100MhzFSB - I don't do overclocking (call me conservative). If they are available, anyone know a good place to order one?

Well, you can use a 100 mhz tbird and underclock it - divide the multiplier by (4/3) so that the clock speed is almost exactly stock speed. Conservative

Save $ on a 100 bus 1 gig. Change the multiplier from 10 to 7.5 and use the 133 bus, = 1 gig. CPU still runs 1 gig and it doesn't care. Conservative.

Are there any 1GHz T-Birds availible ALREADY SET to the correct multiplier for 133MHz FSB? I've been looking, but I can't find anything except expensive 1.2GHz.

I've heard that AMD is supposed to be making them down to speeds of 1GHz.

They are making them at 1, 1.13 and 1.2 GHz The 1.2's are not even really available yet. You can place an order for when they come in. One reseller told me that AMD promised the first shipment in 2 weeks. He assumed he would get all of the available models at that point. You can find them on pricewatch.

yeah, my old religion looked down on Overclocking too.....consider converting! I did! haha

Current Tbirds can easily do 133mhz FSB(266mhz DDR), just lower the multiplier and bump the FSB to 133mhz. Same clock speed.

Conservative.

update - that appears wrong. Apparently the CPU's boot runnign for about 1 second at their true default multiplier, before dropping to the multiplier from the mobo. This means that a 1 gig tbird would try running for a short time at 1.33 ghz - unlikely. I can't find the source... I think it was amdzone. I read it at hwc or ocn (the forums/discussion). lost the thread

Is there any advantage in using a 133mhz `C` FSB T Bird over a 100mhz FSB Tbird with a lowered 7.5 multiplyer? Would the 133mhz T bird overclock better, anybody?

 

[CTho9305]

did you read my thread? assuming it is correct, you might not be able to boot

 

[CTho9305]

read this. that would be a problem, wouldn't it? can anyone answer the question I asked there? (where does the default multiplier come from)

 

[AdamK47]

The problem stems from BIOS level multiplier adjustment. If you were to use physical manipulation, the problem would not accure. That includes L6 bridge adjustment and DIP switch/jumper adjustments.
