Q: Voltage for Siemens DIMM p/n: SIE3264133G72MV-TW-C1B16D ?

Hello all.

I just bought a second-hand motherboard with CPU & 512 MB SDRAM (2x 256
MB).

LABELS
==============================================================
DIMM #1 :

SIE3264133G72MV-TW-C1B16D
256MB-PC133-222-0137-PA 2982

DIMM #2 :

HYS64V32220GU-7-C2 32Mx64 SDRAM
C2812110 PC133-222-520

256MB, Sync, 133 MHz, CL2
==============================================================

Ok, so DIMM #2 is no mystery. I found the datasheet and its voltage is
3.3V.

My question is with DIMM #1...

Is it CL2? And 3.3V? That I don't know.

Seems like a silly question, but I'm asking because the memory voltage
jumper on the mobo is already set at 3.4V.

I haven't installed the mobo, and naturally I want all the hardware
settings (jumpers, DIP switches, etc) to be set correctly so as to
avoid problems and/or damage.

Would using 3.4V instead of 3.3V cause a difference/damage in the long
run? I know most CPU would work fine with such a small differential,
but maybe SDRAM is more sensitive.


Any help greatly appreciated.

Me again...

I forgot to mention something.

In the manual of the mobo (ASUS CUSL2-C), the jumper in question (VIO)
is used not only to regulate DIMM voltage, but also AGP and PCI.

It can be set at either 3.3V (1-2), 3.4V (2-3, default) or 3.6V (3-4).


That's all folks.

RAM #1 is CL2(222). One reason to raise that voltage is for better stabilty
when overclocking. There's really no need to have it higher unless the
manufacturer found it more compatible with a larger amount of ram types. You
might want to check their website for updated info.

That's what I thought.

I'll set that jumper back to 3.3V.

Thanks Dawg!
