Time-of-Day Clock Runs Fast on GA-P67A-UD3P?

[silentsage]

Has anyone else had an issue where the time-of-day clock on your hackintosh runs about 40 minutes fast every 24 hours?

I have a GA-P67A-UD3P motherboard with an i7 2600K processor, 8GB of memory, and a GTX 275 graphics card. The software install follows Tony's guide posted elsewhere.

Just curious. Any fix for this? I don't use a DSDT file, but I suppose I could if I needed too.

I have the same problem with the p67a-ud5

Make sure you are using the kernal flag "busratio=29" and it should fix that.

Actually, that's the cause

Changing the ratio causes the system time to speed up or slow down, depending on the setting.

Official SB support from Apple will fix that.

Does anyone have a good solution for this? I just started having this problem since updating my CustoMac Mini 2011 to Mavericks.

Newest version of Chameleon, DSDT from the database - my system clock is always 5 minutes fast. It's screwing up some of my programs.

I believe this is a bus speed problem, but in my System Profiler, I don't even see Bus Speed listed.

I found this but it's from 4 years ago so I thought it would be outdated:
