OK,
Now that I've sold my A7N8x and ordered a new 845PE mobo, I need to get up to speed on Intel OC'ing.
So to start with the multipliers are all locked as follows
2.26 - 17
2.40 - 18
2.53 - 19
2.66 - 20
2.80 - 21
3.06 - 23
These run at 133mhz fsb, so what's this quad-pumped stuff mean? And how does this work in relation to fsb settings and dividers, etc.?
I know it's 20 x 133 = 2.66MHZ chip, not 20 x 533...
I assume that 533 is 133 x 4 or the memory speed. And when people overclock their fsb they need to slow down the ram with ratios?? Am I close? I've seen some boards that offer dividers like 4:2 , 5:2 etc and some that say 2.0x 2.25x 2.50x etc...
This part's a bit confusing for me after tweaking AMD's.
So...once I get past mem settings, it looks like most setups can hit 160-170fsb speeds...
so, 2.26(17) x 165 = 2805mhz
2.53(19) x 165 = 3135
2.66(20) x 165 = 3300
2.80(21) x 165 = 3465
3.06(23) x 165 = 3795
So, it looks like that big fat multiplier on the 3.06 and 2.8 are solid gold for overclocking, right?? I've been reading a lot of old posts trying to get up to speed on Intel OC but it's taking a while. Any help'd be appreciated.
Here's the rest of the rig.
845PE Mobo
256mb XMS 3200C2
TTGI 520 PSU
Swiftech MC478HS w/ Vantec tornado
Vantec fan control
Prometeia by Jan.
CPU - undecided
R9700 - stock
cdrw, maxtor 7200, etc.
f&s
