Maximus Hero VII Memory issue (2 slots work 2 do not)

[tellison]

Hi,

In my new build I have the following : -

Motherboard: Asus Maximus hero VII
CPU : I7 4970K
GPU : MSI 970


My issue is that I have 32 gb of Hyper X Fury ram (4 x 8gb) and currently only two of the slots on the board work !!

The far two are the only ones that I have had working together B1 AND B2 !!

If I put any memory in A1 OR A2 i get the intermitent q code of 55 which is (memory not installed) and sometimes it will constantly reset.

Things I have tired :

Installing all motherboard drivers
Updating the bios to latest version
Changing the clock speed of the memory manually in bios
Changing all the mountings of the mother board and putting washers on them
Checked for any damaged pins or connectors on the cpu
Reseated the CPU cooler


At a loss here! I know 16gb is more than enough but I have 32gb and would like to use it all!!

Any help is appreciated.

Kind regards,

Hi, Can you post a picture of the CPU socket?

First, what CPU cooler are you using, then are all 4 Fury sticks from a single package? or was it two sets of 2 sticks, or ??? Also what is the model # or data rate of the Fury.

You're welcome. Pins look ok.
Are the standoffs installed in the right spots?
If installing single RAM module in A1 or A2 and starting the board, does the system POST?

Hi both,

The memory is all the same 1888mhz. All sticks work in only b1 and b2! If any of the four are inserted into a1 or a2 they wont boot and shows error q 55 or it restarts every few seconds. A1 and a2 seem dead.

The cooler I use is the stock i4790k with plastic clips, I read somewhere metal causes it to potentially short. Obviously this can't be the issue with the plastic clips!

Then it looks like a board or CPU issue. Try testing the board outside the case, single RAM module in A1..

Hi, i have reordered a new motherboard so I am hoping that is the issue! I will update people later tonight. Hoping I don't have to replace the cpu!!

 

[alexoiu]

ok, waiting for the follow-up.

Dear Alexoiu,

So new motherboard works fine. Up to 32gb of ram!

Thank you very much for your input.

P.S Do you think I need to reinstall any drivers? with the new motherboard?

 

[alexoiu]

You're welcome. Good you've fixed it and thank you for the follow-up.
If same motherboard model, then you don't have to reinstall drivers.

 

[tellison]

Yea, It was a shame I had to reorder a new motherboard! but atleast its now fixed

Again, Thankyou.

 

[alexoiu]

You're most welcome.
