Overclocking & CAS question

[TheGrandHooHa]

To continue my steak of newbie questions:

If I plan on using a 133 (266) FSB, and a 1.333ghz T-bird:

* Should I bump up the voltage on the cpu above the default? I believe the default for a T-Bird is 1.7-something, but should I push it up to 1.8-something?

* Should I leave the DDR voltage at default or raise it (PC2100 crucial, 2 512mb sticks).

* The mem says it comes set at 2-2-2. While I am completely clueless about this area (for now), can it be changed, and SHOULD it be changed to increase performance? If so, how is it changed, and to what should it be changed.

If you raise the bus speed it tacks your memory, so you will want to raise that. Basicaly you can raise the memory voltage on the epox to max, +0.4, and it will work fine, and ensure stability, without adding all that much heat. Now asuming you decrease the cpu multiplier to keep yourself at the same clock speed while raising the fsb, you wont need to increase the core voltage of the cpu. But if you do raise the clock speed either through multiplier or fsb, you will have to rasie the core voltage eventualy. The fastest ram timings on the 8k7a are 8882622, you should be able to get anywhere from 155-165 fsb with those mem timings untill you have to decrease them to get the bus higher.

I don't think the question here is about overclocking, is it? If you are not overclocking, then you can leave both the CPU and RAM voltages at the default values. I would leave the RAM settings at default to start off with too, change them later if you want to try and tweak a little extra performance out of the RAM.

Nelson: Actually, I am overclocking my 1.2 to 1.333 once I get it. Also, I am planning on using 10x133, however, should I make it like ?x150 if possible?

The memory CAS will change automatically once the FSB goes over a certain speed. The memory will go from CAS2 to CAS3 to keep pace with the shorter processor cycles. You can't go to CAS4- which is why you start with CAS2 memory.
