Volt ? on 8rda+

[ayoung]

I have a crappy psu...

When I put my volts higher on my CPU (vcore) on then run prime 95, the +12 and -12 go up (normal @ like 12.2-12.5, and then what im talking about is up to like 12.9-13.1).... not down? Wtf?

Does anyone know why this is like this?

Is it good or bad?

Thanks alot

Adam

Yes, seams like you have a cheap PSU which don't have a separate voltage regulation for +5V and +12V. If +5V line goes down under load, PSU will compensate it and also pull up +12V line. It's not good, in fact it can be very bad for your hard drives, causing them to overheat. And of course, it will limit your overclocking

This also can damage your motherbaord also...I have personally experienced this on one of my 8RDA+'s...fried the +12 MB connector and the PSU...

I thought that these new mobos used the +12v for the cpus power?

no?

Thanks

Not all, 8RDA+ still uses +5V for CPU. +12V is used on 8RGA+ and 8RDA3+.
