Corsair PC2700@147Mhz Help

I just put my 2700 at 147Mhz (140 was fine and had no errors) and it had tons of errors in memt86 but it doesn't feel warm at all! Do i need to raise the voltage? (it is at 2.6V now) or is this the max my memory can go?

    No.
    Overvolting that ram when you haven't even hit it's max hit would be bad. You need to set the timing to the defaults. Probably 2.5-3-3-1T.
    If you want better timings than what the ram is rated for then yes, overvolting would be needed.

    Your CPU prolly cant do 147, your RAM sure can but the CPU cant. I am guessing you have a 133 mhz CPU. For best performace it should be run sync with the CPU.

    What your motherboard and CPU speed and Multiplier?

    Check to see if you memory speed isn't set to a FSB:Mem 133:166 (4:5 ratio - asynchronous). This is the usual SPD setting for FSB266 CPUs and PC2700 memory.

    This would mean that at CPU FSB147mhz your memory is running at 184mhz. Which of course may be too high for it.

    As Mmonnin said, Athlons work best at a 1:1 or 133:133 FSB:Mem (synchronous) ratio.

    Well, i messed around with it a lot yesterday and got it up to 154Mhz, it is running sync with my 1700+. Right now i'm just trying to overclock my memory and keep the cpu the same speed because its quite an old 1700+ and runs really hot.

    Its perfectly stable so if i mess with it more today i can probably get some more speed.

    Since the multiplier on my board (A7N8X-DX) won't go any lower then 9.5 would it give me much performace inscrease if i started to run the memory faster by changing the ratio and running it asyncronous? The mobo seems to use the higher mulitplier when you select 9.0/17.0, is there any way to enable the lower multiplier? That would make it a lot easier to get my memory faster.

    We both said AMDs work better while running sync with the RAM. Run the RAM at whatever the speed the FSB is.

    GOBD - grab a $50 TbredB 1700+ (or $95 Barton 512K 2500+) and sell that old 1700+.
