Any help OCing G.Skill DDR3 1600 cl7?

[Shioka]

Hi all, ive been reading this forum for long time, specially when i have questions and now i decided to update my rig. I bought this:

-i7.4790k
-Asus Maximus VII Ranger
-G. Skill Ripjaws X DDR3 2x4gb 1600mhz CL7 (blue ones) with this code: F3-12800CL7D-8GBXM

I want to OC the cpu in the future and the memory but i dont know almost nothing about memory ocing.. This modules where at the same price than cl9 ones and besides the latency i chose these because of overcloking. I read "XM" is better than "XL" for it and since they are cl7, they should be better, or im wrong?

Could you give a some help with this? and would be worth to relax latencies to get more frequency or i should leave them without oc?

thanks!

Try 1866 at 8-9-9-26 1.56 or even 2133 at 10-10-10-30 1.65 (initially with both, may have to play with voltages) but can try these settings for starters and let us know what happens. The RJ X set is a strong one 😉

Should be able to achieve very good overclock results with combination of hardware. Keep us posted and we will be glad to help and provide pointers.

Sorry for so long time disappeared, but i was waiting until yesterday for the memory sticks.. i was trying today and i can set them @ 1833 8-9-9-26 1.5v. i can see windows is faster now, even at startup but when i try 2133 i get BSOD, first time "page fault in nonpaged area" but now i get bsod "system thread exception not handled", what should i do? relax timings or maybe it would be worst than the 1833 oc?

Try 2133 as above and raise the CPUVTT or DDRVTT to 1.1

Ok, im increasing ddr vtt and at 0.87500 windows started but rebooted after open 2 programs.. At 0.87500 the value turns red in the uefi and you said 1.1, its safe? I mean.. I read max safe ddr vtt for intel is 1.4 so i went increasing until 1.1 and even 1.2 and nothing, after login windows it crashes, now bsod "irql not less or equal"

May have already hit the wall for those sticks
