So nice to hear from you again Soar and especially this time with a happier tale than usual.
Glad it is all sorted for you at last.
Firstly don't bother messing around with the RAM. If it's working ok just leave well alone. I am sure we could squeeze that little extra out of it but you would notice any difference in day to day running so it's not worth the bother.
The beeps is an unusual reasoning that I haven't heard before and I must admit I am skeptical. Most board now run two BIOSes and I have never heard one emit that beep code. Also it is not in the motherboard manuals. I still think it is an error somewhere but if your board is running happilly why worry about it.
I think that your following statement sums up a lot of peoples thinking only usually too late.
If you are not a super qualified and experienced OC'er and do not have weeks and weeks of time to tinker, experiment, and hit and kick your computer many, many times causing lots of dents and scratches, just use the RAM Gigabyte states is compatible with your specific motherboard!
Anyway thanks for taking the time to let us know the outcome which is really useful for the future.
All the best soar
