64Mb Simms on a CyberstormPPC ? Also single Simm and 50ns mem..

I myself use 4*32Mb but iirc you can use 2*64Mb if you put them in 1'st and 3rd simm slot. 50ns will only help if you decide to OC but such delicate and expencive cards as the CSPPC should never be OC'd in my oppinion and still I suggest they get extra cooling.

I think you've got it wrong. These figures are taken out of the air since I'm not sure how the formula is in CPU and ram relations so just humor me and I think you'll get the picture.

Lets say you OC your 060/50 with 60ns memory jumpered to 60ns:
10% = 060/55Mhz and 54ns memory (70ns mem=no, 60ns mem=probably, 50ns mem=yes)
20% = 060/60Mhz and 48ns memory (70ns mem=no, 60ns mem=possibly, 50ns mem=yes)
30% = 060/65Mhz and 42ns memory (70ns mem=no, 60ns mem=no, 50ns mem=possibly)

By setting the memory jumpet to 70ns when OC you instead get:
10% = 060/55Mhz and 63ns memory (70ns mem=probably, 60ns mem=yes, 50ns mem=yes)
20% = 060/60Mhz and 55ns memory (70ns mem=no, 60ns mem=probably, 50ns mem=yes)
30% = 060/65Mhz and 48ns memory (70ns mem=no, 60ns mem=possibly, 50ns mem=probably)

So even if you jumper the card to run the memory at slower speed it's running faster then that. So it's always a good thing to have as fast a memory as possible and use the mem jumper if the memory can't take the speed of the OC'ing.

Jose... yah.. there's conflicting information... I've also hear the think of putting them in pairs and that would spoil the chance of using 2 64Mb's... perhaps you can use 4 64Mb or 128Mb ones just for bragging rights? :-D
