Ok,
I've done a lot of research but still can't get a handle on the role RAM plays in OCing??!!!
The basics I got from Fade2Green514 (OCN member) in a different sit. The following refers to a Gigabyte d/s3 and e6300
"basically heres how it works
you use a base speed to figure out the rest of the clocks in your computer.
for core 2 duo's this speed is 266
base speed * 4 = fsb (in your case 266*4 = 1066)
base speed * cpu multiplier = cpu speed (your case 266 * 7 = 1.86ghz)
im not sure how it works for ddr2 and intel memory controllers, but it also uses the base speed to determine memory clock as well."
Now that all makes sense to me. to start OCing you bump the base speed up until the system is unstable . . . so just for a sample say I bring it up to 300
fsb . . . 300 x 7 (multiplier) = 2.1Ghz Got it, but when does the RAM come into play?
Questions:
1. What I really want to know is where the ram comes into play, DDR2 ram. How does ram speed affect the OC? ddr2 667 and ddr2 800? some equations would be nice, I think better in numbers than in words (=
1a. What?s up with the nomenclature of ddr2?? 667 can be either pc2 5300 or 5400? ddr2 800 = pc2 6400?? so you multiply it by 8 to get the pc2 xxxx number, does that relate some how to a byte = 8 bits????
2. Random question: why does the board list that it supports fsb 1066/800/533. 1066 can't be the limit of the board otherwise it would not be able to OC right?
2a. Is the unit of measure for the fsb mhz, is this also the same used for ddr2 (only divided in ½) ie. 667 = 1334mhz?
My assumptions:
Ddr2 667 will run on a 1:1 with 1334 fsb (being double data rate 667 actually 1334)
1334 / 4 = 333.5 base speed
333 x 7 = 2.3 Ghz
so with ddr2 667 at stock speed your biggest OC you can attain will be 2.3Ghz?
I?m having fun learning all this stuff but this RAM question I was unable to find an article or post that answered it for me.
thanks to all you people who help answerer questions on these forums are great, thanks for all you help in advance.
If anyone wants to check out my planned build and give some feedback I?d also appreciate it. my planned build
