CRC errors on 64bit system

Hello,

Version:  0.4.5 Final (also used older versions, but same problem)
OS: showed below
Install-type: Windows Installer
Firewall Software: NONE
Are you using IPV6? no

I've setting up an testing environment cause I had problems with CRC errors on 64bit systems.
I've got 3 OS on 1 machine.
Win xp sp3 32 bit
Win xp sp1 64 bit
Win Vista sp1 64 bit

Everything I download on 32bit goes right. But when I will download something (most times videos, iso's) I'll get CRC errors. This is only on 64bit systems. Quikpar sais the parts are in good condition.

When I download on 32bit system and copy to 64bit, and then unrar the files I don't get errors.

Example of error while downloading:
2008-11-11 10:04:06,717 WARNING [decoder] CRC Error in (8601801F -> F25D429A)
Someone who can help? :(

Are these occasional warnings or for every article?
Does the download still complete successfully (including par2 and unpack) on the 64 bit system?

Don't remember ever having seen this on my Vista64SP1 system.

No it's not for every article. The download does still compleet, but not succesfully. Normal he repair the rar files, after that he extract them and delete all par and rar files. But when a number of rars has a CRC error, he put all the files in a directory. Sometimes he extract the files but after that the video of ISO is corrupt.

And the problem is, I've tried different OS on my pc. Every OS 32bit works fin, only the 64 bit(win xp or win vista)  failed.

Problem solved.
I tried to repair the rar files manually. It seems like he repaired the files. But he didn't. Quickpar could not verify the rar files  :-X

On the quickpar site they came with the conclusion that it is an memory problem.

I didn't believe that cause I've runned different memory stress tests etc and the memory works fine.

But then I borrowed some other memory. Downloaded again some movies etc with sabnzbd. And what did I see? It's works more then better  ;D

So the memory works fine, but in one way of another there where some errors in it that I could not detect with a stresstest.

I'm gonna send that memory back and ask for new.

Thanks a lot for your help.
