Ok. Let me try this again to avoid further confusion (sorry my original post was horrible, it was typed after not having slept for over 48 hours). Here is the major components of my system (and yes, I am running the LATEST bios and drivers for all components):
MOBO: Gigabyte 890FXA-UD5
Processor: AMD FX-6100 Zambezi 3.3 GHZ AM3+ 95W (FD6100WMGUSBX)
Video: Gigabyte Radeon HD 6850 1GB GDDR5
Memory: AMD Performance Edision 4GB (2x2GB) DDR3 1333 (AP34G1338U1K)
I am trying to change out the AMD memory for a different manufacturer, and I am looking to updgrade to 8GB (2x4GB). I already tried G.Skill Ripjaws DDR3-133 (PC3-10666) (F3-10666CL7D-8GBXH) with no luck. The computer would boot up to the Windows Loading Screen and then reboot. No matter how long I left it, it would just reboot over and over again. even though I have the bios set to AUTO with regards to the memory settings, I made sure the correct setting were being applied after I installed the memory by booting up into teh bios and checking. All the applied settings were correct.
After the memory didn't work in my MAIN pc, I installed it in my other PC which uses the EXACT SAME mobo as my main PC, just with a slower processor and video card. The GSkill worked flawlessly. (I replaced 4GB of G.Skill memory with 8GB of G.Skill memory in the other PC.)
This specific G.Skill was not lsited in the Mobo compatibility list. (the list given by Gigabyte was very short and only listed 3 different memory types for a 4GB stick. I called gigabyte and they stated that the list is incomplete and can use any memory modules that are simular to the ones listed as the list doesn't even include specific matched pairs like the G.Skill I was trying to use).
As far as the system optimization, I NEVER state dthat thios was the case, all I did was ask the question IF that was possible as I read on AMD's website back when I built this PC that thier products (AMD & ATI) were optimized to work the best when an AMD Processor, ATI video card and AMD memory was used in the same system build.
Like I said, my other PC uses the exact same mobo as the one I am trying to upgrade (yes, both use the same bios). The only real difference between the two was that one has $GB of AMD memory, and the other had 4gb of G.Skill memory. The one with the 4GB of G.Skill was able to be upgraded to 8GB of G.Skill (the same pair that my other PC wouldn't boot up with). So, I am assuming that it could POSSIBLY have something to do with the AMD memory?? Like i said, its only a question...
I even took the 4GB of G.Skill from the other PC and tried to use that instead of the AMD modules in teh other PC, and still no luck. It seems as though this specific PC will ONLY use the AMD memeory. ( I even purchased 2 cheap OEM 4GB sticks (non-matched pairs this time) and still teh PC would not boot up correctly. Sorry, but I do not know teh specifics of the OEM sticks as I returned them after they wouldn't work. and yes, I checked to make sur eteh BIOS was using teh prper settings when I installed the cheapo OEM ones also.
I have tried everything and nothing seems to work. I really need to get 8GB of memory in this system asap as teh 4GB is not enough any more. I can see if my PC's eached use da different MOBO, but given that they both use teh Gigabyte mobo, teh G.Skill should work in both, yet it only works in one, and that one DID NOT have the AMD memory originaly installed.
Sorry for the lengthy post, but I didn't want to leave anything out this time.
