Am i undervolting my RAM?

post #1 of 2
Thread Starter 
To put it shortly, im running 2x 1Gb sticks of PC2 6400 Ballistix Tracers at 800mhz and 4-4-4-12-2T timings @ 1.8V, is this voltage too low? I dont see it doing much harm as the computers booted with it at that setting for the past 5months, i occasionally get the odd hang here and there but nothing too serious.

I have noticed that the sticks get rather warm though, is this due to more current being drawn due to lack of voltage, therefore greater resistance?

You should run some memory stability tests to be sure that the current voltage is sufficent; systems hangs could be a symptom of a memory problem. However, you should use the least amount of voltage necessary to be completely stable.

Also, if you increase the voltage, temperatures will certainly increase. The full 2.2v they are rated for is perfectly capable of killing a good percentage of Ballistix.
