Hello all of Toms Hardware land! I am Justin. A mere citizen of this wondrous internet democracy we all have access to. In just a bit I will explain of what my problems entail and you shall make a choice to help or not help. But first, you must decide. Will you join me on this monstrosity of a joy ride? If so. Please continue. Ok, here's the run down. Specs: AMD 64 3200+, 2GB PC3200 RAM (A-DATA) (2X1GB), Gigabyte GA-K8N-PRO Mobo, ATI RADEON X800, 120GB HD. Everything in my computer is stock except my video card and RAM. I have not ever had any problems with anything up until last summer (yes, this problem has haunted me that long, hopefully you can start to conceive how grand my issue is). The problem: Basically i can normally compute fine. Be it surfing the web, iTunes, downloading "things", what have you. Though when i start to multi task this where the problem comes in. It is random though. I could be all at once surfing the web, listening to iTunes, downloading, and installing a game and nothing would happen. But sometimes my problem will hit; Blank Blue Screen of Death. It uses guerilla warfare, very deadly, only attacking with NO pattern. I could just be importing a CD into iTunes and will go all blue and stall. When I try to play ANY game of mine it will crash to a memory error. WoW, for instance will let me play between 5 and 30 minutes then crash to desktop and give me what seems to be a memory error. Counter-Strike Source will let me play around the same time and also crash to desktop giving the memory error from its diagnostic. On my motherboard there are 3 DIMM slots. I have 2 sets of memory; A A-Data set consisting of 2 1GB sticks and a Kingston value set consisting of 2 1GB sticks. With each module I have and no matter what DIMM slot I choose or in what order my MemTest86 test results always are the same. Memtest will get to 20% on its first pass and then will start showing up red errors. Due to this odd consistency I have shunned out of my mind the possibility of one or all of my RAM modules being bad. Because why would Memtest on different modules start to show errors at the SAME time? Another note; My mobo DIMM voltage is 2.5v, my Kingston 1GB sticks are 2.6v and my A-Data sticks are 2.5v, just for reference. I can not get any further with my problem because the Memtest results just lead to many a brainfart. If you have the patience and hardiness to stay with me and read all of this then I am definitely in your debt. If you have ANY and I stress ANY idea of what might cause such...unconsistent consistency with my Memtest the PLEASE let me know. Like I said, the Memtest results are ALWAYS the same no matter how I lay my RAM modules in the 3 DIMM slots. Another thing also, maybe it is relevant, I'm not sure. When I bought this computer it had x2 512MB sticks in DIMM slots 1 and 3 running dual channel. Well now no matter how I put in the RAM modules memtest says its running single channel. Even if I put 1GB stick in slot 1 and 1GB stick in slot 3, it will still run single channel. Is my Mobo suppose to automatically detect and run dual channel? Or am I suppose to manually change it? Again, Thank You so much for any input at all.
