Asus P8P67 Pro - Now this is odd

SimonMaltby · 24 Jan 2011 at 20:19

Been watching all the Asus P8P67 threads where people are having issues and have always counted myself very lucky that mine works perfectly... or so I thought....

I have mine running really well using a 2600K and 2x2GB OCZ 1600 ram.

Today I took delivery of a second 2600K.
When I tried to use the new chip in my P8P67 Pro i started getting the same memory issue people have been describing with the red memory light illuminated.

I have reset the BIOS, done a full battery out reset. and this new chip will only run with either 1 stick of the OCZ ram or Both but at 1066Mhz.

After an hour or so of messing about I put the old 2600K back in and it's back to normal instantly... no red ram LED and fully working at 1600Mhz dual

So what on earth is all that about????

Y, 2600K, L042B076, OCZ C6 1600, Only tried 1253

hey Simon, what was the batch number of your good original 26k was it L039B470?

No the good CPU is L040B690

Simon are you returning the cpu for replacement ?

No because I don't think the CPU is bad.

It works on a Gigabyte UD4 (although the UD4 has a different fault where I can't manually set vcore).

I have spoken to the shop and also requested support from Asus.

Ok have you tried your working cpu from your asus board in your UD4 to see if you can set voltage ?

Yes... and it makes no difference, same issue with both CPU's. I'm 90% certain the UD4 is faulty but that's discussed in another thread.

IMO it's all about the relationship between the CPU and the Memory on the Asus board... some work together some don't it seems.

I will keep this thread updated if and when I get any support from Asus

I had an email from Asus support today regarding the problem... all they offered as a solution was to flash to the latest Bios (Useless!)

Anyway, looking around the forums I decided to explore the pin connection option.
I took out the CPU, gave the underside a wipe and put it back in. I also re-seated the Ram making really sure it was pushed properly in. When i re-booted all was working properly, the RAM issue has gone

So my conclusion is that the CPU needs to be located just right and with good contact. I do wonder about the RAM slots... the Asus board is the only one to use this new slot where there is only a clip on one side.... I wonder if that is causing problems.

Well I know that Asus use a different socket maker than Gigabyte because there was all that talk of damaged gigabyte pins on a reviewer board, I wonder is Asus are unique in the socket maker.

I would also not rule out the RAM connectivity. Although I think the socket is probably the main cause of issues I have to say i don't like the ram slots not having a locking mechanism on both sides... a pointless regression that can only make good contact more likely.
