Memory Question/Help

[Gabbatek]

Hello there, i currently have the 'G.skill Ripjawx 2x4gb ddr3 pc3-12800c9 1600mhz on a gigabyte p67a-ud4 with i7-2600k @ 4.6ghz

im looking to add more memory but the problem is that i can only get these sticks in twos or three's and my cpu cooler is covering one of the space memory slots

so my questions are, will using another branded stick running at 1600mhz cause any problems

and also, occasionally my pc will not start and revert to its normal spec of 3.4 ghz and it will run the memory at 1333mhz even though they are 1600mhz

why is this?

there is no over heating at all, case temp is always below 30, cpu on load is rarely over 65c

You don't want to add a single stick as that will mess up dual channel operation.

You can use lower profile RAM like Corsair XMS3 which matches the speed and timings of the G.Skill exactly and should run at the same voltage (around 1.5V).

And if your PC is reverting to stock speeds during the boot process then there's something in your settings that the BIOS doesn't like when it does its checks.

have you changed the bios setting to run the memory at 1600 rather than linked to your cpu speed ?

yeah i have changed it to run at 1600

should i have it set to auto which defualts to 1333

i really do not know why, even if its not overclocked its defualt is 1333 even though it should be 1600

Because the maximum officially supported speed is 1333MHz.

1600MHz is deemed as overclocking so you have to set it manually.

And no, you don't leave it on auto at 1333MHz.
