I immediately had issues with BSOD and the PC locking up randomly. I swapped RAM, GPU and even the motherboard but it didn't help. The only parts left were the CPU and the power supply. I took an old 550W psu from Sun and swapped it in... No more BSOD or lockups....
Now I have a dilemma. I thought I was buying the cream of the crop when I picked Corsair. This was literally the last part I thought would give me issues.
Where do I go from here? Should I RMA the CS650M and try again or just return it go with a different manufacture? If so what manufacturer?
Just RMA ... that is what a warranty is for ... all components are assembled by humans ... and sometimes even the best fail ... as long as they stand behind their stuff ... it's all good. (PSUs are scary ... it could have been much worse ... it could have taken most of your system with it)
Corsair is one of the holy trinity of PSU manufacturers IMHO
How can a faulty PSU cause BSODs or lock-ups anyway? If the PSU has a problem, the system will either not turn on or just shut of eventually. So if you swapped everything else, it CAN ONLY be the CPU which you should just RMA it and get a new one.
Some new information. At least some of the system freezing are caused by the fan controller on the R4.
I have disconnected it and moved the fans on to the motherboard but system freezes continue in windows. They happen either at startup or at times of high cpu usages. If i run prime 95 the system freezes as soon as I start the test. If it can make it past the start it usualy continues on for a long time before freezing.
Turning up LLC, Vcore and CPU\NB voltages seems to have little effect. In fact in some situations the higher the voltage the worse it freezes.
I may just try rmaing the CPU. Not many options left.
and bump up the bus ratio instead. maybe you have some kind of the same issue then i have. i cannot bump up my multiplier any much higher then 22, wenn it start stress testing with a multiplier of 23 then my systems freezes aswell.
i dont have this issue wenn i let the multiplier at stock 20, and just bump up the bus ratio a bit.
