AMD Memory Timings

[HisoKa]

guys... i head that if you wanna use 4 sticks of memory instead of 2 in any of NF4 mobo with AMD cpu u gotta loosen uo the timings... is that true...? coz im planning to upgrade my system from 1GB to 2


cheers

I think thats because most (AMD)motherboards can't run 4 sticks in Dual Channel, you'll need to adjust the Command Rate to T2 instead of T1.

Who agrees with me.

hmm.. never tried before... if that's true... then u can only run 4 sticks at single channel then? no matter how u loose up the timings and change the command rate...?

I wrote that wrong, most Motherboards can't run 4 sticks in dual channel T1( I think one of the newer ATI based ones can). Other settings like CAS and the like should run the same with 2 or 4 sticks.

The new Asus AV8-MVP runs 4 sticks DDR at 2-2-2-7 T1 and with a bit looser timings and more voltage all the way up to 315mhz!!!
Looks like I have my xmas rig mobo selected . . .

Thanx and another correction needed is it don't run 4 sticks at 1T, so knock about 4% off my mental overclock predicted, and it is still awesome! :lol:

Completely agree! I'll never CF, but I'm probably going to end up with one for the mad OCs and price/performance... *drools*

 

[RichPLS]

I probably won't CF either, but you never know what deals fall at your grasp within reach!
