Pepsican Posted June 5, 2015 Share Posted June 5, 2015 Hi everyone In thinking through the build for my music playback machine (based roughly on CAPS), I had a thought about the memory. Many boards support both low voltage and regular voltage memory. Is one, theoretically, inherently better than the other? I can imagine that low voltage memory would draw less power and thus would induce less jitter. At the same time, with low voltage pushing out ripple noise may be harder. I genuinly don't know. It could also be that it doesn't matter. What is the opinion here? Does it matter which type you pick? And why? Thanks!

Purely theoretical, no measurements to back it up, but lower voltage on the signals going to and from the RAM chips should decrease the amount of EMI inside the case. Whether that is important for audio purposes, who knows. John S. Link to comment
EuroDriver Posted June 6, 2015 Share Posted June 6, 2015 At the end of this month, we will be comparing SQ with HQP doing PCM to DSD with - ECC on server board with Zeon - Corsair DDR3 on H97M-D3H - Paul Pang DDR3 on H97-D3H in Munich we were using Corsair DDR3 on DH61DL speculating lower voltage + less noise + stabler power supply - more errors Look forward to your tests and experiences :-) Sound Test, Monaco Consultant to Sound Galleries Monaco, and Taiko Audio Holland e-mail [email protected] Link to comment

completeluxury Posted June 6, 2015 Share Posted June 6, 2015 does low voltage memory have the same power draw as normal voltage ram? if it does, wouldnt that increase the current draw, thereby possibly having worse EMI? Link to comment
Pepsican Posted June 6, 2015 Author Share Posted June 6, 2015 lower voltage + less noise + stabler power supply - more errors Look forward to your tests and experiences :-) According to Puget sound, the reverse is true. Low voltage RAM is more stable than normal RAM, so your errors would decrease. The reason they give is that less power (lower voltage, same or less amperes) results in less heat. https://www.pugetsystems.com/labs/articles/Technology-Primer-Low-Voltage-RAM-150/ Not sure how solid these people are, but it is interesting. Any chance you could a low voltage memory test to your scenarios?

It doesn't. Same amperes or less.
