Quoted from Lindsey:What's the specific issue that can be caused using these? I hate to throw gas on the fire but I'm genuinely curious because I've never had any issues using these and there shouldn't really be any based on the specs for the RAM outlined in the data sheet.
There is no issue.
If there was not enough voltage, you would simply jumper over a diode.
Easy. But I've not seen a game that has ever needed it.
