I have recently purchased a Geil product that i have is the So-Dimm Golden Dragon pc2100 DDR 512 MB 266 Mhz. The computer I have is an IBM T30 w/ windows xp. The problem I am having is outlined in there support info here is what they say:
Q: I installed GeIL DDR memory module and my Windows won't start every time I boot, and crashes almost immediately even if it does start. What did I do wrong?
A: On some motherboards, the memory voltage sensor is not accurately calibrated and the "DIMM Voltage" is being mis-represented in BIOS screen. Set/adjust the memory core voltage to 2.7 or 2.8 volts. All GeIL memory modules have passed the torture test at 3v to survive in this PC market filled with all sorts of different grade power supply units and motherboard voltage sensors.

Ok I the question I now have is how do I change the voltage?

Depends. The easiest way is to delve into the BIOS settings (hold down the 'DEL' key as you boot up) and look for something along the lines of "memory voltage" and adjust it. If no such entry exists in your BIOS then it's a hardware adjustment using jumpers on the motherboard (a PC technician's job), or update your BIOS but only when you are sure the update gives you what you need.

I have searched the BIOS for any voltage changing settings. I have not found any settings. So an other words time to take the computer to a PC tech or just sell this chip and buy a different one?

Getting a different brand of memory-chip is not guaranteed to solve the problem unless it's unique to one you already have or varies from one memory brand to the next. So changing the memory brand might work.

It probably explains why I've had memory compatibility problems with my PC, despite getting the right type and speed. never occurred to me that some memory chips might be less tolerant of voltage variations than others. I did eventually find a module that works no problem -- exactly same spec as the one that wouldn't allow my PC to boot -- just a different brand. So hopefully that's all you need to do.
