everything on auto
except
vdimm: 2.1v
dram settings: 4-5-5-15

I have 2 problems.
1st, I can't seem to get it stable at 4Ghz, at least at under 1.4v in BIOS which is the max I want to give it.

2nd, and this is the biggie. I have sound popping, cracking noise.
I though maybe it was an issue with my old Audigy LS pci soundcard, so I tried the onboard soundmax & had the same issue. So I thought maybe the PCI bus was "dirty" and had some issue with signal distortion, etc.. So I got a X-Fi PCIe card and I'm still getting the popping noise. I tried using my speakers, headphones, etc... still the same issue. WTF, could it be that would affect 3 different soundcards? (Audigy PCI card, onboard Soundmax, and X-Fi PCIe card)

Could it been my powersupply or something supplying a dirty power signal?

Upgrade bios to 1004, or 1006 ( you can find them here ftp://ftp.asus.com.tw/pub/ASUS/mb/socket775/P5K-E/ )

Disable all Spread Spectrum

Enable Load-Line Calibration (Will get rid of most of your vdrop)

Bump your NB voltage up to 1.55 or 1.70 and SB to 1.20

This Should get you where you want to be.

As for the audio problem there could be a number of reasons here are a few that come to mind:

1. Some other device/s sharing resources (irq and/or mem i/o addr's) with your sound device and not playing fair (USB, SATA controller, etc..).

2. Other devices firing interrupts at an uncontrolled fast rate, will greatly
increase the bus latency, witch is a common cause of pops, and crackles.

I would just try the process of elimination, remove devices until it stops,
USB devices, pci cards etc.. then go from there.
