how would i go about OCing dual channel 1x8gb and 2x4gb

[banshee43]

do i have to do anything differently? Or can i just treat it as a normal ram OC?

Make sure you put it in the right slots, or it'll all be running in single-channel.

Alternatively, I believe you can have both the 4GB sticks in channel B and the 8GB stick in channel A. It still works as dual-channel if each channel has equal amounts of RAM.

i know that it works in dual channel but when i am changing the timings do i have to change all of them or will they all change together? also what is a good ram stressing tool to check stability?

Timings will apply to all sticks, so you'll be bottlenecked by whatever the slowest stick is. I don't think you'll have the option of setting the timings individually per stick.

Memtest86+ or Prime95 in Blend mode.

ok thats what i was thinking too. thanks

to tighten the ram timings should i just change one at a time? im new to OC. also does OC negate the stock ram speed and timing settings ie. the suggested 1333, 1600, 1866 and the timings that go with them? and do i have to change the timings within the bios, then reboot and stress it??
has anyone OCd vengeance? any timing suggestions?

How long would you suggest running memtest86+ to check for stability?
