First, I've done several of these, and love the ability to increase the performance for cheap. I I Recently did the Xeon 771 to 775 Xeon mod on a Dell Optiplex 780 DT. The processor is a x3363 Xeon, and the Bios has been updated to the latest (A15) downloaded from the Dell website. The system has sufficient memory (4 GB/PC-6400). The system boots and operates but seems to me to be a good bit slower than I normally see, so I'm looking for some insight into what may be causing my problems. If there are any.
Before I did this mod, I checked to insure that the Opti 780 motherboard (Q45 chipset) supports the Xeon modification, and apparently it does. But, it only supports the 3xxx (mine's a X3363) series. However, it states that the 5xxx series Xeon processors are not compatible with this motherboard. My problem/question is this: After installing the x3363 (Quad-Core/12m cache) Xeon, I booted the system (note: it booted fine) and entered the Bios to set all the parameters. I then rebooted to install the OS (Win 7 - 64bit). At the beginning of the boot process I get a warning message from the system that says "System doesn't support the installed processor", and get the option to press F1 key to continue, F2 to enter the Bios setup, or Press F5 to run onboard diagnostics. I then press the F1 key to continue with the system boot, and the system continues a normal start up. I've been able to install the OS, and completely update it. I've installed all the system drivers without any problems, and the system appears to operate fine, just operates a bit slower than other systems I've done. So apparently, the system actually does support a 771 to 775 modified Xeon although the system states that it doesn't. My concerns are these: Is there a way to bypass the initial warnings at start up without having to select the F1 key every time? Also, any ideas of why the system is operating a good bit slower than I expected? By that I mean, if were to re-install the original C2D processor I feel the system would actually be just as fast or possibly even faster than with the mod. Any ideas, or other things to check?
