Gigabyte P67A-UD4-B3 / Dual Channel Memory Question

Peter929 · 24 Mar 2011 at 12:43

Hi There

So I have just replaced my Asus P8P67 (which I had nothing but issues with) with a Gigabyte P67A-UD4-B3.

Installed it and everything is looking good, apart from 1 issue.

I have 2 * 4GB corsair sticks of memory which I wish to run in dual channel.

The problem I have is dimm slot 1 is blocked by my CPU cooler,

I tried to put the dimms in slots 2 and 4 (in the hope it would run in dual channel) but the pc fails to boot (even to the bios splashscreen), it just keeps restarting.

I currently just have 1 * dimm in slot 2 and it runs fine (but with only 1/2 my memory and in single channel).

My question is, SHOULD it boot and run in dual channel with memory in slots 2 & 4, or does it HAVE to be in slots 1 & 3 to run in dual channel (in which case i need to solve the issue with my CPU heatsink).

Your thoughts?..........

Looking at the motherboard manual (page 16), installing memory modules just in slots 2 and 4 should be fine and work in dual channel mode.

Perhaps one of your memory sticks in dead. Have you tried switching out the single memory stick that is installed now and see if that stick also works fine? I would also suggest running memtest on each of the stick (individually if you have to).

Both memory sticks work fine, they worked on their own and as a pair in the Asus board, and also they both work on their own in the Gigabyte board.

Could it be something in the bios setting which is stopping the PC booting with the memory in slots 2 & 4? (I.E. i need to boot into the bios with 1 dimm installed, alter settings, refit the 2nd dimm and try again?).

Not an answer to your query as such but there does seem to be a problem with P67A-UD4-B3 going into a repeated restart mode without getting to the BIOS screen - mine does it frequently.
A couple of comments in this thread too:

2 and 4 will work fine for dual channel

which cooler is blocking slot 1? I am considering this mobo and ram

Have you tried plugging these in, turnin it on, as soon as it restarts, force a bios reset then see if it boots afterwards? I had a similar issue with my ud7, when it happened I just did that and it booted fine.

I've got the arctic cooling freezer 7 pro, with the fan facing towards the front the case so it exhausts through the rear of the case it totally blocks slot 1,

With the fan facing upwards so it exhausts out the top of the case then you would be fine with a dimm without a heatsink, however with my corsair vengeance dimms, the heatsink still catches on the heatsink.

Hmmm, I wonder why mine wont boot when they are in these slots.

I will have to have another look at it all tonight and see how I get on.

Quick suggesting run memtest86 and find out if you have a duff stick or ram or if you have a duff memory slot.

And I would suggest updating your bios to the latest version if you have not done so already.

I have the same fan and mobo and also have to use slots 2 & 4. My set-up appears to be running really well too.

Same cooler and board here but thankfully, my airflow is reversed so the rear fan is an inlet and the fans at the top front are outlets (basically from when I had W/C and there was a rad there). As a result I have the fan on the cooler facing the back of the case.
