Xeon 771 to 775 mod?

[BigScott]

Yes, X Xeon 5460 in lga775 Asus p5g41t-m lx plus G41 chipset. . CPU with no need for adapter. As it was pre-modified. Only issue is to flash bios with micro-codes .before installing new CPU,as it will not boot with new CPU but will reach bios.prep bios flash first. Do a bios update with MM-tools. save updated bios on USB flash drive. shut down,Now install Xeon CPU. boot to bios.Go to bios ez-flash process. choose hard disk option -flash drive. update settings. your done. reboot and go to windows.

This worked fine. But now if any experts can answer this? Now that the XEON is working,and X5460 natively supports R-dimm memory.Will the mod now allow me to use R-dimm in place of U-dimm?

Doubtful as the motherboard chipset likely isn't compatible with registered memory.

I have a Xeon X5460 on my Gigabyte GA-P35-DS3R working just fine @4.1 GHz and with regular non-ECC DDR2 modules.
The issue will be the microcode update, some boards will work without them, and there will be just some features of the CPU missing, others won'T work and you will need a actually compatible LGA775 CPU.

Updating the microcodes is not just updating the BIOS as you need to save the BIOS file (either by backupping it from the board or downloading it from the manufacturers webside), patch the code into it (unless you already have a file with the microcodes inluded) and then have to flash the modified version onto the board.
After all that is done, you can insert the new CPU.
Weither you are cutting on the socked or drilling on the CPU you have to make sure the chip is inserted correctly.
Since the brackets are no longer guaranteeing this, you need to rely on the markings on CPU and socket.

And yes, the type and amound of memory you'll be able to use is still dependent on the board, or to be more precise the chipset built into it.
