Are you sure your RAM is DDR3 as your MOBO is a DDR2 MOBO, and DDR3 and DDR2 have different RAM module slot positions see http://www.buildcomputers.net/ddr2-vs-ddr3.html
As Crucial say:
Memory Type: DDR2 PC2-5300, DDR2 PC2-6400, DDR2 (non-ECC)
Maximum Memory: 8GB
and ASUS say:
4 x DIMM, Max. 8 GB, DDR2 800/667/533 Non-ECC,Un-buffered Memory
Dual Channel memory architecture
Also, Asus MOBOs can be fussy with RAM, so also try with some other DDR2 RAM installed......http://dlcdnet.asus....N-E_SLI_QVL.pdf
Furthermore, with OS X Mavericks, all your kexts should be in /System/Library/Extensions on both the USB flash drive installer and on the OS X Mavericks target HDD
Also you have installed more than just the essential kexts.....and some kexts are not needed by you, .......
and why would you need the AtherosFix.kext?
See my OS X Mavericks nForce install guide post #4 on how to generate your own DSDT,aml file
For running OS X successfully on an nForce + Intel CPU MOBO you invariably need a IDE (PATA) optical drive jumper-set and connected to the MOBO as Master and OS X installed on a SATA HDD.
I also recommend using a USB keyboard and USB mouse with OS X rather than PS/2 keyboard and PS/2 mouse, and then you will not need
The important kexts you need to add for OS X Mavericks to run with Internet access are
Remove NullCPUPowerManagement.kext if setting up Native Power Management in OS X.......
Modify your org.chameleon.Boot.plist file to include
Reset /System/Library/Extensions/ kext ownership and permissions and force kernelcache re-creation via these Terminal commands:
sudo chown -R root:wheel /System/Library/Extensions/ sudo chmod -R 755 /System/Library/Extensions/ sudo touch /System/Library/Extensions/
For good measure, manually delete the kernelcache and other cache files in /System/Library/Caches/com.apple.kext.caches/Startup/.....
For audio, you need to look here for OS X Mavericks + Realtek ALC883 sound
Please post any further questions on installing and running OS X Mavericks on your 650i Asus p5n-e sli MOBO in my OS X Mavericks nForce install guide rather than by PM and here because I obviously focus on checking my guides more frequently than the whole of IM......Go to the full post
