Question RAM speed VS CPU speed? I'm Confused!

RAM: 32GB (4x8GB) Matched G.Skill Trident-X DDR3 CL10 2400MHz RAM (F3-2400C10Q-32GTX)

CPU: i7-4770k

I checked before I bought the RAM and they were listed on the supported list for my MB (GA-Z87-HD3). I installed them and enabled XMP mode 1. They automatically configured to run at 2400mhz.

I have by most standards a fairly old system now and am running an i7-4770k on stock.

I'm a bit confused as my MB claims to support the RAM @ 2400mhz but the i7-4770k processor (LGA 1150) only claims to support RAM up to 1600mhz.

I only installed the RAM about three weeks ago and initially ran it at 2400mhz but I have been trying to diagnose a fault and have recently clocked it down to 1600mhz (yet to see if problem is resolved).

I appreciate you are not obligated to offer me free technical support but I wonder if any of you clever people can advise from your experience? Should I run this @ 1600 or 2400 with my stock 4770k?

Any advice you can offer would be much appreciated!

Best regards,
Tom W
 
The 4770k only supports 1600mhz native RAM speed. In order for you to run the RAM at higher then 1600mhz, you will need to overclock it. This is where your mobo RAM speed comes into play. When you select XMP, you are overclocking the RAM to 2400mhz on that board.

I would run it at 2400mhz as that is the purpose of getting 2400mhz RAM.

Thank you Mr FeelinFroggy :)

Running it at 1600 didn't eliminate the fault anyway so I'll put it back to 2400 and keep scratching my head..

Next stop GPU.

All the best,

Test each module individually to see if one performs differently than others. You can run a memory test to see if each are error free, or a stress test to place the system under load and force any instability. This is the best way to eliminate RAM from the troubleshooting equation.

Thanks for the advice! .. I ran memtest86 for over eight hours @ 2400mhz with no errors, I think I need to look elsewhere for the error. GPU Next then MB if that doesn't solve it.

Thanks for the reply,
