Hello again, friends;

This is an update of my last post (http://www.tomshardware.co.uk/answers/id-1711028/1600mhz-ram-running-1333mhz.html) where I was mounting one 8GB DIMM (www.kingston.com/datasheets/KHX1600C10D3B1K2_16G.pdf) limited at 1333mhz due to JEDEC. If you take a look at that post, you will see that no option solved my trouble, due to the fact that my mobo is really limited at the time I try to OC.

Here is a remember of my rig:

MB: ASUS P8B75-M LX PLUS
CPU: I5 3330
RAM: 2x8GB 1600Mhz CL10 (Kingston HyperX Blu) -actually, I have two modules, over only one of the first post-

GPU, SSD, HDD, etc., are missing; I guess it is not in relation with all of that.

Well; XMP isn't working, and there are only two option in Ai Tweaker of my mobo: Auto or XMP. Manual doesn't exist here, and I don't know if it's a problem of my mobo, or if this mobo doesn't support manual timings (is really limited for OC; it could be possible). I have seen that P8B75-M LX has manual timings, where the user can select them with his own. In mine, I can't modify tRC nor voltage, and if I take a look at SPD, it's supposed that these DIMMs are limited at JEDEC 1333mhz. How it could be possible? My rig can reach these speed (1600mhz), why I have this limitations?

Thanks for all (and thanks again for Tradesman, who helped me a lot in my last post, yet the trouble persists :( )

PD: Sorry again if I have grammatical mistakes... I'm not english.

Hello again, Tradesman! My CPU allows those timings, so it shouldn't the problem. I've seen that in CPU-Z the frequency space (where it has to appear the actual freq) is missing, so I can't see it. It could be possible the fact that my RAM is having 1600mhz (activated in BIOS) but it doesn't appear in CPU-Z?

Thanks again! :D

Tradesman, you're the man. I didn't have the latest CPU-Z version. Now, I can see freq, and it's 798.2 Mhz (for each DIMM, I guess). So, finally, can we say that the problem is solved? :p

I have some picks that pass 800Mhz, so I'm happy for now... I have spent three/four days breaking my head with that, and the trouble was a non-updated software! Thanks for your patience, Tradesman, I'm very glad to have had your advices! :D
