I really have 3 questions:
Question 1 - I have 2 memory modules, one is DDR2-800 the other is DDR2-667, My FSB RAM ratio is 1:1 and the modules are running at 250mhz. I am about to change timings and my first question is, which module should i have in which DIMM slot? does it matter since both are running at 250mhz(well below stock speed)
Question 2 - If I adjust timings, will it change them for both modules?(I don't see timings for multiple DIMM's in the BIOS so I assume it will change them for both
Question 3: I heard the best way to optimize timings is to change each number one at a time and run benchmark/stability tests. This makes sense, but does it matter which timing's I change in what order? Or can i just start with CAS and go down the list in order?
Hi newcomer and welcome to the Tom's hardware forum.
1- The RAM modules are different speed, in that case all the RAM only can run to the lowest speed (667MHz) and don't care the slot where u install the RAM module.
2- Yeah, the mobo only can handle one timing specifications for the RAM.
3- U need change this specs: CL, tRCD, tRP and tRAS. Set the rest in auto and the voltage to 1.8V.
Ok so my RAM timings are now 3-3-3-1-2T stable with memtest, is this good? also you said to increase voltage to 1.8v, I thought that increasing the voltage would only help me get higher clock frequency out of my RAM which I don't need since it's only at 250mhz or am I wrong and it helps timings too?
