Data corruption after install

[x2PhaNToM]

Hello,

 

i've recently installed Leo4All on my machine, and now have a problem with data corruption, which i never had beforce on my Asrock VSTA 939NF6G (nForce 430). (Now I have the Asus M2N SLI (nFroce 560 SLI))

First I thought it is caused by the AppleNforceATA.kext by MeDevil, so i plugged my hdd onto my Sil3512 SATA controller, but still have the same problem.

When copying files from the DVD Drive (also plugged in onto Sil3512) to the HDD the MD5 sums are not equal. Also the same problem shows up when downloading files from LAN or Internet (Realtek 8169S).

As mentioned before, I never had this issue with my old mainboard. It worked about 3 months without any corrupted data or any other faults.

Is there a way to get this to work correctly?

I will test my RAM now, and will copy some files in Windows ...

 

//EDIT:

I've tested my RAM with memtest, and got no errors. In Windows I also get no errors when transferring large files.

 

//EDIT2: I've got the same problem with Ubuntu Linux -.-
