F3-2400C10D-8GZH + ASUS P8Z77-I Deluxe + Intel Core i7 2700K

I picked up this kit of F3-2400C10D-8GZH from newegg for my new build. I'm trying to use it with a ASUS P8Z77-I Deluxe which supports 2400 MHz (O.C.) and an Intel Core i7 2700K. I've tried just about everything I can think of and it still won't run at the Speed & Timings this ram is supposed to. I set everything in BIOS manually (Ram Speed/Timings/Voltage) and haven't had any luck. I also tried both XMP profiles and the darn thing just won't boot It will run at 2133 stock & 2194 when over clocking the CPU. Anyone have any ideas? If I can't run it at 2400 are there some lower timings I can use to run it at 2200?

Thanks,

You can't achieve DDR3-2400 with that CPU, you need Ivy Bridge (i7-3770K)

DDR3-2200 is possible, you have to raise BCLK host clock (seems like you are already doing it). You have the 2700K, so it should be capable of DDR3-2200+

BCLK 103-104 will put you in DDR3-2197 to 2218 range, you can even go higher and see what your CPU can do.

Keep us posted on the results!

Thanks for the info, any advice

Thanks for the info, I had a 3770K but sold it to my friend and bought the 2700K. Ivy Bridge overheats, was running 5-10c more than my 2700k with the same Antec Kuhler 920. The mobo auto tuned my to 5047 MHz today and the ram is in the spec I shared. I can live with this ram since it seems to run good and will have headroom for over clocking

I've never messed with ram timings before so could u shed any light on what I should try? Should I just run the ram at 2200 with the stock timings and lower each individually until it becomes unstable? Also, I heard I should do the max frequency oc, then timings, then command rate. Does this sound like a good plan?

Thanks and will keep you posted on my results!

That's pretty much it, experimentation, might be able to drop the CL to 9 at 2200, at stock DRAM Voltage or slightly higher
