How far have you pushed the voltage on your memory?

    Following conversations I have been having recently I am wondering just how far it is safe to push the vdimm voltage of memory to get that little bit more out of the fsb....

    I've come to the conclusion that the best way to do this is to ask you guys what you're running and how far you've been (with the voltage ;) )

    I personally have never taken it any higher than 2.9v....

    i've never felt too comfortable about running it higher than 2.8V for long peroids of time. cant remember why but thats the number in my head :worried: :confused: hardly scientific i know..:D
    i've never seen too much of an improvement at 2.9. that could be why..

    Never run mine at 2.8V for more than benchmarking, for some reason that number's in my head too :eyebrow:

    Usually run mine around 2.6-2.7V

    i have had mine up to 2.75 but never saw the need for any higher than that
    what is PC2700 technically meant to run at?

    3.3v is the highest I've put through my RAM, default RAM voltage for DDR is 2.5v but it's usually set at 2.55 on most boards by default.

    Yes it works fine but i'd expect it to have a very short life if I ran it at that all the time :)

    hi,

    how can u set it to 3.3v. my mb only allows me setting up to 2.8v and my ram is running at 2.8v all the time.

    I ran some PC2100 at 210fsb at 3V for a year, worked fine but then I sold it.

    Currently running PC3200 at 255fsb at 2.8V 5-2-2-2 :)

    Yum, Winbond chips :D

    CatKing: It depends on your motherboard. Mine only goes up to 2.8V too, but some go much higher.

    My ram runs at 2.8v as I can't be arsed to change the jumper on the motherboard but if I want to go higher I just get out a resistor to up the volt but I haven't seen the need.

    Is it really nessasary to run your ram at higher voltages!!! seriously, you're not going to squeeze anything out of the ram.. :wallbash:

    It's not necessary no, but it helps keep the system stability when it's running at higher speeds. I have mine at 2.8V all the time because at less than that I can't use all the fastest timings like I do now.

    Kasius trust me it helps, I had DDR530 out of my XMS3500 with 3.3v up it.
