Hi everyone,

this is my configuration

Motherboard Crosshair Formula IV
Processor AMD Phenom II X6 1090T
Video Card # 1 Sapphire Radeon HD5870 Vapor-X 1GB DDR5 256-bit 875MHz
Hard Drive # 1 OCZ Vertex 2E 120GB SSD
Hard Drive # 2 Samsung Spinpoint F1 1TB 7200rpm 32MB
Hard Drive # 3 2xSamsung Spinpoint F3 2TB 5400rpm 32MB
Hard Drive # 4 2xSamsung Spinpoint F4 2TB 5400rpm 32MB
Optical Drive # 1 Blu-Ray Samsung SH-B123L/RSBP Retail
Power Supply Cooler Master Silent Pro M1000
Case NZXT Phantom Black
Sound Card Creative X-Fi (Motherboard)
Monitor Samsung T240 GTG 2ms
Operating System Windows 7 Ultimate x64

I have a hard time finding any compatible 2x4gb memory kit, this mobo is like a lab rat raised in a complete sterile enviroment when it comes to memory compatibility or i am the unluckyest person in the world.

I've tested Mushkin 8GB DDR3 1600MHz Black Frostbyte Dual Channel Kit and a Corsair 8GB DDR3 1333MHz CL9 XMS3 Dual Channel kit rev. A and 3 more OEM nobrand 2x2gb modules, since i bought the system i have yet to have it run stable, i crashes a lot less with the 2gb modules then with the 4gb ones.

Also there is the problem of availability in my country, even if i find some one the internet they might be US only like the crucial memory, the cost of importing those are astronomical.

So i ask you guys do you know TESTED to work memory kits of 2x4gb prefered 1333+ mhz.

I've been trying to get my system stable for over a month now, i'm pretty dissapointed and frustrated by now, but hope dies last.

Thank you all in advance.

A addition, this exactly describes what i am experiencing with the ram modules, http://forums.amd.com/forum/messageview.cfm?catid=319&threadid=136652&enterthread=y
Anyone heard for phenom II memory controller problems to be true? How could i contact a amd representative to be certain. How to test for it?

you can check out chew's oc guide which has memory that has been tested to work 24/7 stable on his profiles.

I can't find any 2x4GB modules in that thread they are all 2x2GB witch does not help me much. Any other leads i have yet to find someone using 2x4GB modules.

What country are you in by the way?

x3style · ‎01-17-2011

Thank you for the reply, i am in Romania so i will have to purchase memory from the european market, i'll check to see if patriot distributes in Europe, i would also like if you could specify if u are using a sixcore CPU, as i have heard rumors that 16GB is only supported on CF IV from X4 downwards and that you cannot use 4GB modules with x6 cpu's.

That is cool, Romania is a very beautiful country! I did some searching on Patriot, and two sites that they say sell their products in Romania are http://www.dc-shop.ro/ and http://www.extreme-computers.ro/ I am using a Six Core Phenom II, the 1090T Black Edition. Oh, I forgot to add the voltage on that memory defaults to 1.65V, but I had to raise it to 1.85V to make everything stable and good. Good luck, and let me know if I can help out any more!
