Why don't you get DDR3 2400Mhz CL10 ram and lower it to 2133 CL9? That 1.77V now is a bit overkill for DDR3 and mainboard+cpu ram controller.
Don't see the point in buying new sticks when I can get 2133 anyway -- even if I do need to over volt them so badly. (I only use this O/C for gaming)
A number of factors are affecting me:
-Northbridge overclock reduces memory latency and increases bandwidth but seems to strain the RAM more
-High CPU overclock seems to strain them a little
-I am using the tightest possible timings for my mediocre ram. I can increase timings and drop voltage but then I'd no longer be on the absolute bleeding edge of its limit.
-I've also got 4 sticks, 2 are rated differently
Took me weeks -- and for a long time, voltage was actually doing nothing, no matter what combination of O/C or timings. From this I've learnt that over volting RAM only helps bring you back from being
JUST BARELY over the line of instability.
/\ Don't know if anyone else has had better results with RAM voltage than me?
