First off, I apologize if I'm asking what has already been asked. I tried searching for an answer and couldn't find one so here I am.
I have a Lenovo G505s without the dedicated graphics (only the embedded graphics in the A10-5750M APU) and it has an Insyde BIOS. Now I am looking at putting in some 1866MHz 10-10-10-30 RAM into it, but would like to make sure that the BIOS isn't going to try running it at some JEDEC standard (since 10-10-10-30 isn't standard from what I can tell). I have seen other people put 1866MHz RAM into this machine and it does work, but I can't find any reported timings or if it actually runs at 1866MHz (I have seen people say that the CPU is capable of that speed, but the mobo locks it to 1600MHz). Does anyone know if the Insyde BIOS will lock the memory down to something other than what the RAM is capable of or if it will actually run at the XMP profile?
If the BIOS does lock it down, does the BIOS have the code in it to allow me to run the memory at it's full capabilities? If not, will implementing Coreboot for the BIOS give me that capability? Is it not even the BIOS that would do that, but some other part of microcode on the BIOS chip?
Also, I have seen that Lenovo uses Insyde's secure dealio thing that makes flashing modded BIOS's through software impossible. Is this true? Is the only way to flash a modded BIOS on this machine is to do it with an external programmer? Is this BIOS RSA signed like the HP ones and therefore rendering any modding useless?
I believe that my BIOS version is 83CN53WW, but I don't currently have the machine near me to confirm. I do know that it is what is included in the current 3.00 update on Lenovo's website:

I have extracted the .bin file from the installer package so I can provide that if needed.
Thanks!
