So I bought 4x 8gb Kits of the GSkill Trident X 2400 CAS9 ram for my new 3930k / Rampage IV Extreme build. (I wanted 8gb sticks but stock was not available at the time.) I do a lot with VM's so I wanted 32GB Total.
I am aware that I would probably not be able to run 8 dims at 2400 spec. but they were inexpensive so even if I had to run at 2133 / 1866 or relax the timings a bit I would be fine with that.
I tested the 4 kits individually using stock timings, etc that the kits were designed for.
VCCSA and VTT are both at 1.2V, Mem is at the rated 1.65V.
Two of the kits work fine at 2400 with stock settings. I can even run all 4 sticks together that tested fine at 2400 but without some time / voltage tweaking they would not run stable at 2400 but run perfectly fine at 2133 which was pretty much expected running multiple kits.
I am running Prime95 Blend in order to test the memory stability. 2 of the kits will run overnight with no issues either individually or together.
The other two kits barely work at all.
One kit will not run 2400/2133 or 1866. I have been able to get it to run at 1600 with some tweaking but that is pretty much unacceptable from a cost perspective.
The other kit will not run 2400/2133 but will run 1866 with a bit of tweaking which is really not good.
I am pretty much at a loss of what to do because if I mix one of the bad kits with my good kits then I have to clock everything down to satisfy the bad sticks or everything is unstable otherwise I paid way to much for 1600 ram with relaxed timings lol.
The serial #'s on the kits are fairly close together ending in 375,376,391,392,393,399,400.
Do you think I am looking at an RMA situation?
I have been building PC's for over 20 years so I am not a noob but I would at least like the kits to be able to run the rated speed when tested individually. I know it is not a mb/cpu issue as I have 2 kits that do it perfectly well individually or when paired up.
