Overclocking Newb Heading for Disaster

[linear]

Alright I'm getting ready to try to overclock my system. Specs are below.

From what I understand i just need to up the FSB? I have to figure out what that is first. I'm assuming its around 133 or 166 MHz since my ram is PC2700=166MHz (whatever the defaults are).

What the hell are the memory timings?
Partial Quote from another post:
"
memory voltage at 2,75v now
(before the fsb went up: Cas 2-3-3-6 at 400mhz,
now after fsb is set to 214: Cas 2-4-4-8 at 333mhz)

"
What is the x-x-x-x? I figure the first number is the CAS but what are the others?

Your almost there....

I am currently running my timings at 2-3-3-6. In P4P800 terms, the numbers would be:

2 = CAS Latency
3 = RAS Precharge
3 = RAS to CAS Delay
6 = Precharge Delay

and sometimes you'll see posted a 5th number - Burst length (mine's at 8).

Occasionally I've seen memory companies (and forum posters) state their timings in a slightly different order with CAS Latency always first but the way listed above is generally the most common.

Heres a good read on memory, http://www.corsairmicro.com/memory_b...707/index.html

wow thats nice that it reads it to you. I like that.

Yea it is a neat feature!

So I understand it correctly. If i change the ram timings that does nothing for the system clock right, meaning it doesn't effect the CPU speed or system clock (FSB), it only speeds up the RAM, right?

I saw on newegg that somebody got these timings for my ram (given in sig below) 2.5-6-3-3

Where 2.5 = CAS
6 = tRAS
3 = tRP
3 = tRCD

Does this sound right?

Attached is the wcpuid of my system. Since my system clock is 100MHz i should be able to increase it to 133 right? Since my ram is 166MHz.

oops picture was too big

When ocing, start bringing up the front side bus a little at a time testing the stability of your cpu. You'll want to find where your cpu is stable then start manipulating timings on your ram. If your ram is set to auto, your system will adjust the timings accordingly so wcpuid might report timings different from your bios. I have seen this. Also, your ram will come from the factory with predetermined timings - my ram is 2.5 CAS.
