hi i have corsair vengence 1600mhz 8gb 2x4gb dual channel ram and it's set to 1333mhz, i did some digging around and i read the difference isn't much so i thought i wouldn't worry about it and the thread said that the motherboard normally chooses stable clocks or w/e, but then i thought i may just be looking in the wrong places. so i'm just wondering should i put it up to 1600mhz and what impact will it have, if any my mobo is an asus p8h77-m no gpu, i read the igu is affected by ram? can someone validate that. i7 processor btw

Thank you and sorry if i missed anything

the 1600 speed is not a overclock sped on your ram it a stock speeed. the system will be a little faster. but it will still be stable. in the asus bios in the ai setting it under dram speed/timing turn on xmp profile. then your ram will run at 1600 speed.

ok so i tried to put it to 1600mhz but it tells me overclocking failed, even though the ram is 1600mhz any help? i only changed the mhz and not the voltage or anything i'm not really sure whats wrong

mobo support says 1600mhz only supported by 3rd gen :/  oh well thanks anyhow smorizio

so i set it to xmp saved and reset, same thing happens it says overclock failed for some reason i must be doing something wrong

Edit: i found out my ram part number CMP8GX3M2A1600C9(XMP)

on the asus memory support website it says

CORSAIR CMP8GX3M2A1600C9(XMP) 8GB(2 x 4GB) DS - - 9-9-9-24 1.65V

will i have to change voltage for this to work?

check that your running the 0804 bios. also in the dram speed make sure memory speed is set to auto. also make sure asus over clocker on the main page is set to standard if it set to over clock there it changes the ram to cpu ratio from 1:1 to 1:5 and can cause issues.

Hello op. I am the person you are looking for. You cannot enable XMP profile for your motherboard. XMP profile means that you are overclocking your ram. You are on a H77 board which means you can ONLY oc your GPU. I too also have a h77 board so i know. There isnt much difference anyways.

Sandy bridge cpus stock speed for ram is 1333 while ivy bridge cpus stock speed is 1600. To get your ram any higher than 1333 is impossible unless you are running ivy bridge.

yeah, nothing has worked i'll be changing mobo in half a year or so and this mobo will go with an ivy bridge pentium once its out to make an ok reliable pc
