Gigabyte mb - GA-MA78G-DS3H Bios F4

The system is not very stable - it randomly freezes (need to push reset button) and randomly reboots. This does not depend on cpu load. The system can be stable for a week (24/7) and can halt 3 times a day afterwards. Memtest shows no errors in dual mode. AMD overdrive stability test pesses. No problems with 3DMark'06!
So I've decided to tweak some secondary memory timings and noticed that EPP profile that is enabled by default has tWR value 8, while the automatic settings set it to 6.
Here is a screenshot of everest with EPP profile
And here are the timings set with EPP enabled in BIOS
The M.I.T page also shows 6 in auto timings when EPP is enabled. 6 is the largest value that can be set through bios.
Today I've flashed the new BIOS f5h. I have done "Load Optimezed Defaults" before and after flashing. EPP Timings and voltage were disabled after "Load Optimezed Defaults" in f5h. EPP settings were enabled by default in F3 and F4 bioses.
But what is more strange the Auto column on M.I.T page shows the timings that were in bios F4, but the spd column looks strange now, something like 4-6-6-18. There a now such timings in spd as shown in cpu-z and everest (see the sceenshot).
Is it a mobo bios bug?
Some help in tweaking secondary memory timings to increase stability would be appresiated. Now I am testing the stability with increased trfc 105->127.5 and tRC 22->24.
