ECC Memory in P7P55 LX

[steculshaw2010]

Hello,

Just wondering if any of you guys can help me.

I recently bought a Core I5 with P7P55 LX Mobo.

I had some 10600R memory (Regestered ECC 2GB) x 2.

This works ok in my system, however I recently aquired a couple of 4GB 10600R (again Registered ECC) DIMMS and for some reason the pc wont boot with these.


I first thought it was due to ECC registered but after some hoking around on the net and also trying the 2GB DIMMS i believe this not to be the case.

Can anybody claify (could it be volatges)?

Thanks in advance, appreciate any feedback at all.
