Alienware X51 R1 - Upgrading to R2 Motherboard
I recently purchased a new X51 R2 motherboard online, and the seller just informed that I had to do certain things when I go into the BIOS and insert my service tag. Otherwise; I could end up breaking my motherboard for good.
Does anyone know if this is true? If so, what are the steps, and would it work in my case (upgrading from R1 to R2 Mobo)?
Also, do I need to mod my case in any way in order for the motherboard to fit?
Thank you in advance.

Hi,
Whenever you replace you Motherboard you should manually enter the Service Tag in the BIOS. However, if the previous owner's Service Tag is already there, you won't be able to change it because it can only be done if the BIOS is in Manufacturing Mode. Follow these steps to check if the option is available:
Note: If you enter yor X51 R1 Service Tag on an X51 R2, your system will be recognized as an R1 on AlienAutopsy and the Dell website.
The X51 R1 and X51 R2 case is the same so you don't have to modify anything for the Motherboard to fit. Although, some of the ports on the back might not fit the same spaces in the chassis.

Both parts should be the same so there's no need to change anything. You're good to go!

The I7-4790K, 3.6GHz is fully compatible with the X51 R2 Motherboard but not with the X51 R1.

Thank you so much for the info. I have one more question: Do I need to change the power & I/O boards or would it be fine?
Thanks again.

One more thing, I know that with the new BIOS (A06) the motherboard now supports haswell refresh CPUs.. So, I'm wondering if the 4790"K" isn't an exception -and would work with the X51's H87 mobo- since it is confirmed to be compatible with the Z87 chipset?
I'm hoping it would, since the only major difference is the unlocked multiplier. But I'm not quite sure.
The reason I'm asking is because the 4790K has a better TIM which would prolly help with the temps. And I'm also planning to take the processor out some time later to use it in a new build with a Z97 chipset motherboard, and would love to have the option to overclock it in a different setting.
Thank you again for your time and help, it is truly appreciated.

Hi,
I have just made this upgrade and unfortunately noticed that the R2 is a socket 1150 and the R1 uses socket 1155.
So I now have to decide to either source another R1 board or upgrade my processor. Annoyingly the board in the case connecting the front USB sockets to the motherboard appears to also need changing.
Am I wrong?
Kind Regards
