wevsspot Posted February 7, 2014 Posted February 7, 2014 Just me, but I wouldn't run 1.75v through my DDR3 memory modules except for benchmarking or bragging. I certainly wouldn't do it 24/7. Not to mention the amount of voltage that you'll probably have to push through the memory controller to hit those speeds. Share this post Link to post Share on other sites More sharing options...
Jklein Posted February 7, 2014 Posted February 7, 2014 See I was thinking that because I imagine the difference between 2400 and 2600 is not going tone worth it I would be better off just enabling amp and going with 2400 MHz. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted February 7, 2014 Posted February 7, 2014 Personally I think that would be a smart choice. Share this post Link to post Share on other sites More sharing options...
Jklein Posted February 7, 2014 Posted February 7, 2014 (edited) Is there a formula for how many watts in a volt? And how many degrees in a watt? Edited February 7, 2014 by Jklein Share this post Link to post Share on other sites More sharing options...
ohldboy Posted February 7, 2014 Posted February 7, 2014 volts * amps = watts volts =amps/watts amps= watts/volts 1.6 volt* 1.5 amp = 2.4 watts Share this post Link to post Share on other sites More sharing options...
Jklein Posted February 8, 2014 Posted February 8, 2014 So lets take an fx8350 for example its wattage is 125 and 1.3 volts if you 125\1.3= 96.15 round up to 96.2 so its 96.2 amps watts = amps*volts 96.2*1.3= 125.06 round down to 125 watts volts = watts/amps so 125/96.2= 1.3002 so we round to 1.3 volts And correct me If I'm wrong this comes into play when choosing your psu because you need to enough amps on your 12 volt rail assuming a single rail to handle all your video cards CPU etc. so for example if you had a a system that a FX 9590 stock tdp and an R9 290x you would need at least 44 amps on your 12 volt rail to support them because 520/12= 43.3 but you would round up to 44 obviously. So do I have the basics right here? Share this post Link to post Share on other sites More sharing options...
ccokeman Posted February 8, 2014 Posted February 8, 2014 HIgh speed memory usually has a trade off in speed vs Latency. AMD rigs respond well to higher speeds when going from 1600 to 1866 to 2133Mhz. Over 2133Mhz you really need to start tweaking to get fully stable. Share this post Link to post Share on other sites More sharing options...
Jklein Posted February 8, 2014 Posted February 8, 2014 Right and that's because the controller in the processor usually is only 1866 or 2133 depending on whether its am3+ or kavarie right? Share this post Link to post Share on other sites More sharing options...
ohldboy Posted February 8, 2014 Posted February 8, 2014 Note: motherboard VRM process power for CPU. There is usually a slight power consumed in this. Share this post Link to post Share on other sites More sharing options...
Jklein Posted February 8, 2014 Posted February 8, 2014 Personally I think that would be a smart choice. Right but correct me if I'm wrong but don't the power VRM's like those that power the CPU get their power from the 12volt rail on the psu?

Waco Posted February 8, 2014 Posted February 8, 2014 Right but correct me if I'm wrong but don't the power VRM's like those that power the CPU get their power from the 12volt rail on the psu?Yes - almost everything in a modern PC uses the 12v rail.
