BIOS Setting for ASRock N68C-GS4 FX.

[setha]

Hi,

I was able to update BIOS to the most recent version 1.50. However, I am unsure if the setting below is correct. I don't want to lose performance due to any wrong setting in the BIOS, basically.

Processor Type: AMD Athlon(tm) 64 x 2 Dual Core Processor 6000+ (64 Bit)
Processor Speed: 3000 MHz.
Microcode Update: 40F33/0
L1 Cache Size: 256 KB
L2 Cache Size: 2048 KB
Total Memory: 8192 MB Dual-Chanel Memory Mode
DDR II_1: 4096 MB/400 MHz DDR2 800
DDR II_2: 4096 MB/400 MHz DDR2 800

Advance PCI/PNP Settings
-------------------------------------------------
PCI Latency Timer [32]
PCI IDE BUSMASTER Enabled

Here are some of my questions. Please suggest anything that might improve my setting.
- Why L1 Cache Size and L2 Cache Size are not the same?
- Why would my BIOS automatically set PCI Latency Timer to [32]?
- What happen if I set PCI Latency Timer to higher and what that number should be?
- What is "PCI IDE BUSMASTER Enabled"?
- Should I disable 32bit option on each SATA disk?

Please note I am using Linux Mint 18.

Thanks.

L1 and L2 are physical components of your CPU, they can't be changed. They don't match because they are different amounts of memory.

64 bit PCI is not that common so the default of 32 is probably best. Do you even have any PCI cards installed?
Increasing latency is rarely a good thing, probably support for even more legacy PCI devices.

Are you using an IDE drive? Probably want that on if you are.

No idea what bit options there would be on a SATA disk. Usually only a few modes to pick from and everything after that is handled by the controller. Might be encryption related.
