better CPU/mobo/ram combination for OC

[kikkler]

i'm going to buy a new computer soon and I would like to theoretically be able to run it at 3.6Ghz, 5:4 and Cas2
so far i've been thinking about to options -
1) 2.6C, Abit IC7, 2 * Mushking 3200 Black Level2
2) 2.8C, Abit IC7, 2 * Corsair XMS 3500

now, the main problem lies in the CH5 problems and their difficulty to top 255Mhz at 5:4. that's why I have to buy some BH5 rams (the Mushki, option 1) when taking he 2.6, because i'll have to run it at 277Mhz.
when taking the 2.8C (option 2), this 255MHz barrior becomes insignificant, 255 * 14 = 3570, which is just fine.

of course, going with option 1 will give me a better overall performence because the higher FSB, but going with option 2 will give me better performence because the tighter timings..
so as you see i'm kinda having a hard time deciding between the two... any help would be excellent

so the 255 mhz limit is a mobo issue that'll hopefully be resolved by a bios update by abit

... if you can run 255 1:1 @ 3570 with the 2.8C then i say go for that...

The timings for that will have to be 3-4-4-8- or worse. I've seen such an overclock and it made "only" 6,500 on Sandra. I am passing 6,000 on 283 using 5:4 with 2.5-3-3-6. Tighter timings are essential. 250:200 with Corsair at 2-2-2-5 using 2.8GHz can give him awesome performance with 3.5 GHz. Keep in mind that it is not sure that the chip would be able to do 3.5 GHz at all.

while the 255Mhz 1:1 is a mobo problem, the 255+ Mhz 5:4 / 3:2 is a memory chips (CH-5) problem.
the corsair has it, the mushkin doesnt

that's not what i wanne do.. the timings would be awful. i'd rether run it at 5:4 (CPU at 255Mhz, memory at 204Mhz) and keep the timings at 2-2-2-5 or something

well...

Geil gold dragon pc4000 can do 1:1 @ 2-3-3-6 @ 254-5 mhz

which is pretty good...

 

[kikkler]

Geil GD4000 comes at 250Mhz, 2.5-7-4-4
as i said, they need tons of voltage. there's no way it'll run at 255, 2-3-3-6 with 2.8v

then vmem mod your board like i did!!!

easy to do and you can get 3.1 volts with no problem!!!

btw, the abit board undervolts the vmem voltage so 2.8 is actually 2.75

you may want to get the ic7-g max3 cuz it has vmem volt up to 3.1 i believe

geil gd is good up to 3.1 volts and still unde rwarranty

Really?
The hell! What is so special they cannot do that with standard IC7/IS7?
In either case the price of that board is spicy. Beside I have a really bad experience with their AT7 "Max" model where no Linux would install easy. Makes me weary of all this "Max" designated boards.

hehehe

then like i said... vmem mod the board!!!
