LGA 771 to 775 Adapter (MOD) – Run faster Xeon CPUs in a Core 2 Quad motherboard

  

Tested motherboards

Below you'll find a list of motherboards that have been tested with this MOD.

We've also included some motherboards that should be compatible (based on their specifications) but haven't been tested yet. However, we clearly mark those as Not tested yet, so you can tell the difference.

Predicted compatibility

On most of the motherboards, we've tried to predict what Xeons will be compatible based on the motherboard specifications (like chipset, max FSB, and max TDP), supported LGA 775 processors, and the Xeons people have tested. The prediction should be very accurate in most cases, but since we haven't actually tested all of these ourselves, we can't guarantee it.

We recommend that you also verify compatibility yourself using our LGA 771 to 775 motherboard compatibility guide (which was shown earlier in this guide).

Let us know if this mod worked on a motherboard that isn't in our list

Please leave a comment with your:

  • Motherboard model number (and revision if it has one)
  • Xeon model number (and stepping if you know it)
  • (Optional) chipset, max FSB, max TDP, and supported LGA 775 processors

This will help other people that are also using your motherboard.

ASUS P5W DH Deluxe 975X / ICH7R 1066 ≥ 150 Q6700 All (see notes)
Worked: X5450 (E0) (see notes), E5405 (E0)

Notes:
  • You can probably run 1333 FSB CPUs if you underclock the FSB (this will also run the CPU at a lower speed)
  • X5450 required underclocking to 2.8 GHz to be stable. They also added Xeon microcode.
  • ASUS says 1333 FSB isn't supported.
ASUS P5WDG2 WS Professional 975X / ICH7R ≥ 1333 ≥ 130 Q9550 (C0), Q6700, E8500 (C0), E6850 Probably all
Worked: X5450 (C0)

Notes:
  • CPU support list doesn't list the Q9650 as compatible, so E0 stepping Xeons may not be supported without a BIOS MOD
ASUS PN57A-VM ≥ 1333 ≥ 120 At least Q9550 (C0) Probably all
Worked: X5450 (C0)

Notes:
  • Couldn't find cpu support list, so can't verify if Q9650 or E0 steppings are supported
  • 1 reported they needed to disable "C State Tech" in BIOS to stop slow booting and high CPU usage

Biostar g41D3C G41 / ICH7 1333 95 Q9550 (C0), E8600, E6850 All (see notes)
Worked: E5450 (E0)

Notes:
  • Although the CPU support list doesn't show Q9650 as supported, the BIOS does contain the microcode for it, so it should work.
  • Person running E5450 said they got an error message that the CPU was over 95 W (even though it wasn't). Press F10 to bypass and boot the system anyways. Adding the Xeon microcode to the BIOS may fix this problem.
Biostar P35D2-A7 P35 / ICH9 1333 ≥ 115 Q9300 (officially) Probably all (see notes)
Not tested yet

Notes:
  • Core 2 Quad Q9650 isn't listed in the CPU support list, but the BIOS contains the CPU microcode for it, so all 45nm quad core Xeons will probably work.

Notes:
  • The E5450 and X3363 were both tested by the same person
  • I think this is a special desktop/laptop hybrid, so it’s definitely not a typical system.

FAILED: See notes

Notes:
  • Multiple people have reported that Xeons don't run at the correct speed and that the BIOS does not support Xeon microcode, so the system may not be stable
  • Don't recommend trying the mod with this motherboard.

Worked: X5450 (see notes)

Notes:
  • Recommend going with 95 W and lower CPUs only
  • X5450 (120 W) wasn't stable until the multiplier was reduced from 9 to 8, which reduced the speed. Also needed to disable Speedstep in the BIOS.

Notes:
  • 1 person reported an E5440 didn't work (tried adding xeon microcode and adapter and Xeon worked in another system). However, since it worked for another person with an E5440, it's likely some other installation error causing the problem (like not cutting the socket tabs off correctly).

    Xeon E5450 works on ASUS P5G41T-M LX3

    Hey what’s the difference between x5460 and e5460 is it just the tdp? Is on faster then the other in anyway ? Just over clocking wise? Can X take much more a punch then E?

    Have Xeon X5472 Modified from a Chinese site working on a Gigabyte P43T-ES3G Version 1.3 board Does it need any bios changes? Boots fine and Bios recognizes it.
