I just tried adjusting the rails on PSU and the there are two pots.
One seems to do nothing, the other does both the 5v, and 12volt rails. Problem is as soon as I barely break over 12volt like 12.03. Then that put s the 5volt line at 5.33 or higher.
Id like to know if that is safe and if it is safe to go a little higher.
I would like to have my 12volt rail up to 12,25or 12.33(this is where it tops out.)

Thanks

3.3v would be orange to ground and 5v is red to ground.
Hope that helps you.
Sorry just read your message... Gave an answer by your title.
Although i don't like to say increased voltages are SAFE, i'd say +10% is safe.
Just stay under 3.6 on 3.3/5.5 on 5.0 and 13.2 on 12 and you should be good as long as over voltage protection doesn't kick in.

the titles a bit misleading sorry.
Thanks for the quick response, I have the PSU sitting outside the case and pulled apart. I didnt want to reinstall it if I had to just pull it again. My case Is just too small and its a pain.

Later

Poki is prtty much right on. You only need to push the 3.3v rail above 10% if you are planning on shoving alot of volts into Vdimm.

Unless your 5v and 12v rails are fluxing alot under load, then 10% will do nicely. You will need the 3.3v rail to be higher than whatever your Vdimm is.

Remember you will probably have to increase your 3.3v rail even more as you put your system under load to maintain a strong 3.6v
