my question is do ram have to be in the same clock settign( the ram timing thing that i dotn get) to work with each other. i bought some cheap ram(PNY it was on epecail) and put it with my xms ram it wouldnt work. try put it in dif slots and no luck. the 2 cheap rams work together but as soon as i put the xms ram the computer beeps. but the xms works by it self the only thing that is left the setign of the ram right? if so whow i change the settign of the ram.
