It's meant to combat EMI problems.

It won't stop EMI generation by your CPU/Board though. Sometimes you can hear a "whine" or "squeal" coming from your board and it can stop that.
Though that noise is generated because one part in the power delivery system is operating at a different frequency than another part.
When both parts are in harmony you do not hear the noise.

Some boards that use Electrolytic Capacitors have that same noise though, and it's a failing capacitor and something you need to address quickly. Either through RMA or self repair.

I very new to extreme overclocking and just got a new system..Crosshair IV and the bios is really confusing compare to my 790FXTA-UD5:( confused.gif
I got one which say AVDDA is that the CPU PLL?
CPU loadline calibration has %, if i put it on 100% dose this mean it eliminates the cpu Vdroop?
And if i set 1.6++ on the cpuV why do i get CPU over voltage error but on my 790FXTA-UD5 i set it on 1.8 and not a problem....
And on ram i got settings like DRAM V which is the voltage setting for the DDR
but there are also VDDR, DRAM CTRL REF voltage and DRAM DATA REF Voltage:confused:
Your info helps alot and answered some of my question

If you could share some info about DD3 rams, on what those setting does, and effects specially on DRAM drive

So in my case of MSI 890FXA GD70 the voltage settings in bios cell menu are as follows:
CPU VDD Voltage
CPU-NB VDD Voltage
CPU Voltage
CPU PLL Voltage

Which voltage should I adjust to correctly set my CPU & NB voltages?Thanks in advance:D

Are you sure you want to adjust voltages on that board with an overclocked X6 ?!

Anyone knows why raising VDDA doesn't change anything? 4.0 is not stable regardless of that feature... what for is that?

Bum chip, bad luck, bum board, or bad settings.

Make a thread, fill out your system sepcs in UserCP, and give all the information possible in the thread so you can get the best help.

I need a little help here. I think there is a small possibility that my computer may not have a good enough PSU. Not sure how accurate these readings are in HW monitor, but the low reads worry me quite a bit, because I do not have a budget for a new PSU. TY in Advance. pic below.

BTW, these are with all settings in BIOS to default, except Turbo core off, the cpu and other load line calibrations off.

Don't trust software to read out voltages.

Your PSU is definitely a solid unit.

If your voltages were that low, your computer wouldn't turn on.
