Hi Jtashmore,
Welcome to Sony Community and thank you for your inquiry!
The only BIOS version released for the model VPCEB3KFX is R1140Y8 on 10/6/2010. Regarding the memory, since the maximum memory allowed for this model is 8 GB, we can't guarantee that putting more than 8 GB will work on this laptop. It may not detect it or it may slow down your unit or worst case your machine won't start and you'll have to return it to original configuration.
It will still be your decision if your want to try it but make sure that you get some help from experienced computer technician.
Regards,
Jen
