New MOBO, CPU, PSU, AND RAM. No memory detected.

Epic Swifty · Jan 26, 2016

Bought a new motherboard, RAM, PSU, and CPU. Pm turns on but no video output and an error code that apparently means no memory detected. I have tried a single module, two modules, different modules, resetting CMOS, and repeating CPU.
MOBO : Asrock fatality z170 gaming k6
PSU: Corsair rm1000i
RAM:Corsair vengeance lpx 4x4GB
CPU: i5 6600k

EDIT
Forgot to say that I have also tried each slot when only using one module.
Also, this may be nothing to do with this issue, but we every time I power on the pc, whether I use the front panel power button or the button on my Mobo, the first time the pc powers on for a few seconds, then off. But the second time I press the button, without fail it powers on.

Have you tested with single RAM module each slot?

Epic Swifty · Jan 26, 2016

Yes I did do that sorry should have put that in original post. Thanks for the suggestion.

alexoiu · Jan 26, 2016

No problem. What's the exact model of RAMs?

Epic Swifty · Jan 26, 2016

The name on amazon is Corsair CMK16GX4M4A2666C16R Vengeance LPX 16GB (4x 4GB) DDR4 2666Mhz CL16 XMP 2.0 High Performance Desktop Memory Module - Red.
Just copied this because I'm not sure what you mean by model, the speed as it says is 2666MHz.

They should work. What error code getting?

Epic Swifty · Jan 26, 2016

I get a 55 on the 7 segment display at the bottom of the Mobo. According to the manual that means memory could not be detected, please reinstall the memory and CPU (which I've tried), then if the problem persists try single modules etc.

It would be highly unlikely (near impossible) that all 4 sticks or all 4 slots would be bad. Do you know if that cpu has an integrated memory controller? That could be defective, but again unlikely as they test cpu's before sending them out for sale.

Epic Swifty :

When reinstalling the CPU, have you checked the socket if any bent pin?

Epic Swifty · Jan 26, 2016

I'm not sure about memory controllers for definite, but from reading a page I found this paragraph to do with quad and dual channel ipwration:
It's also important to note that, while Haswell-E and X99 supported quad-channel operation, Skylake and Sunrise Point will only do dual-channel. Presumably Skylake-E will again bring back a quad-channel integrated memory controller.http://arstechnica.co.uk/gadgets/2015/08/intel-skylake-core-i7-6700k-reviewed/

This dosnt make sense to me though, when I read it it sounds like Skylake dosnt support quad channel memory, but then why does my Mobo have four slots? Sorry if this seems silly to ask but I'm genuinely not sure a at this point what that means.

Epic Swifty · Jan 26, 2016

Also I have looked at the socket and from what I can see there are no bent pins, but I have slight sight problems so may be missing it. But the code sounds like it is a problem with specifically the memory, could it mean the processor is having an issue as well rather then the RAM?

alexoiu · Jan 26, 2016

The memory controller is integrated into the CPU and 55 indicates that memory isn't detected. Try taking a picture of the CPU socket. It's easier to check it.
If no bent pins, I'd RMA both board and CPU.

mjslakeridge · Jan 26, 2016

Dual channel means that 2 sticks of ram work "together", so in your motherboard with 4 slots, slots 1 and 3 will work together and slots 2 and 4 will work together (I am guessing that is the configuration). So, yes you can use all 4 slots.

If the memory controller (probably integrated into your cpu-although I looked at the specs for the cpu and didn't find any mention) is defective that "could" be the reason the error code says ram not detected. Do you have a friend with an X99 supported motherboard that you could test the ram in?

Epic Swifty · Jan 26, 2016

No I don't have anyone with an X99 board and don't have one myself. As for the bent pins on the Mobo, as far as I can see it dosnt look like there are any.
Is there anything else I can try before I try to rma the CPU and board? Because it was he'll getting them delivered, CPU was resent 3 times and motherboard was 2 weeks late

so I'd like to avoid it as much as is possible.

mjslakeridge · Jan 26, 2016

Sorry about the reference to the x99 board. I misread something. As suggested above, try taking the best quality picture of the cpu socket that you can and post it here (I haven't posted any pictures to this forum, so I can't tell you how, but I am sure someone else can).

Epic Swifty · Jan 26, 2016

Oh ok that's a relief was trying to think of someone who would have an X99 board

as for the picture of the CPU socket I have 2:

When I tried to click on either of your 2 links, it says "Album is empty".

Epic Swifty · Jan 26, 2016

Ok sorry try this:

Haven't done this before so if it dosnt work I'll just find another way.

alexoiu · Jan 26, 2016

There's a pin missing and two bent.

Epic Swifty · Jan 26, 2016

Ah ok thanks didn't see that, so should I start by just trying to rma the Mobo?

alexoiu · Jan 26, 2016

mjslakeridge · Jan 26, 2016

Ya, I think the bent/missing pins are the cause of the ram not being recognized. Good luck and post back when you get the new mb and everything is up and running.

Epic Swifty · Jan 26, 2016

Thanks everyone for the help I've arranged to get a replacement of the motherboard in the next few days

alexoiu · Jan 27, 2016

You're welcome.
