Are latencies important when matching DDR2 memory?

    Hi,

    I bought a new custom built Pc and it came with 2x512 Corsair ddr2 chips already in the PC.

    I bought a pair of 1gb super talent sticks for my not realizing that the timing for these do not match the corsair timing specs. will this cause my pc to act up? i did get a blue screen error msg that had 0x000000?? (cant remember the last 2) i googled and said it was a ram memory issue.

    also does the placement of the memry modules mater into the board? i have 4 slots 2 black and 2 yellow offset.

    thaks in advance

    here are the mobo and ddr2 specs

    i see that the super talons are not on that list. but my pc will recognize them.

    my cpu will see all four sticks (3gbs) but when i take out the super talons my pc works better with out freezing. is the timing screwing up the pc?

    Could be the timing, or faulty chips. It seems you've narrowed it down to the memory so I;d be returning it, or better yet exchanging it for memory thats on ASUS's QVL list.

    that will teach me to impulse buy on ebay. i guess i can resell them on ebay. first though i will try running with only the super talons alone in there and see if its stable. i'd rather remove the corsair 512 than the talon 1 gb

    Just a caution, be careful with ebay. You probably already know that...

    But glad to see you got it working...

    With newer RAM, especially DDR2 800 (I'm not really sure why), but motherboards can be extremely picky about what they will and won't accept. And not have matched pairs or sets of four in many cases leads to the situation you're in now.

    Maybe I'll look for your Corsair on Ebay! :D

    Whenever you add or replace DDR2 RAM you have to match type and with that comes latency (CL2,CL3,etc.), speed and voltages otherwise...well, you already know what happens...:D Cheers!
