XMP BIG Problem

allocen
Level 7
So my short problem is that due that i enabled the xmp profile for my 4 kits ram, each of 8GB at 2400Mhz, the pc could no longer
start. No signal, not boot splash screen, no nothing.

My specs:
Motherboard: Maximus VII Formula
Processor: Intel i7 4790K at 4Ghz
Ram: 4x HyperX Savage at 2400Mhz each
Cooler: Noctua D14
Video card: MSI R9 280
HDD: 1 TB WD
SSD: Samsung Evo Pro 128gb & Samsung Evo 250gb
Power supply: Seasonic x-1250

So how this started:
So at the recommandation of a friend, he said to me: Why you have bought 32gb ram at 2400mhz with XMP Ready if you
are not using it at its full capacity. (My ram is 4 kits of 8gb each one at 2400mhz, same model HyperX Savage). Without having
the xml profile enabled my ram ran at 1666 Mhz. So i decided to go to the uefi bios and select the xml profile where i saw i had 2 profiles
to choose from, so i selected the first one. All good, till the restart where the pc could not longer send any video signal or the boot
ROG Splash screen. I presed a couple of times on the reset button at the back of my motherboard, clearing CMOS. Finally started but
i was pressing for nothing the DEL button or F2 because it did not want to enter in the BIOS neither way. Tried again and again reset
and reset and nothing, i still got the same result over and over again the code from my motherboard was 55 saying that ram is not
inserted, but what the hell, there is inserted. The funny part is that after each time clearing the CMOS i could enter in Windows but i could
not enter into the BIOS. The weirder part was that even the AI Suite 3 could not start anymore saying something like "failed to call procedure"
or something like that. So this morning i took the ram out from the slots, last 3 ones and i putted them back. At my surprise, i could finally
enter into the BIOS, that code on motherboard this was A2. Before seeing that the xml profile was still enabled even after hundreads
of reset, i pressed already f10 and save, so it was too late... and after the same result i could not longer recieve any signal video
or at least the boot splash screen. So even i press again the reset button i could still not enter into the bios but i can boot into the windows
but after a next reboot i'll have the same behavior as above.

Please anyone, help me, or explain me why is this **** does not work.
I'M DESPERATE
I do not know what to do anymore, i am panicked.

Thank you, Daniel

Yea but i'm so angry and panicked at the same time, afraid that i won't damage the pc's components with this sort of things.

Nah....worst thing that will happen is it won't boot etc. and a lot of BSODs can corrupt BIOS meaning a fresh OS install but not much worse than that...

Ya, but for me is hard that i have the NOCTUA D14 cooler, so the latest 3 kits of ram are under exactly the right fan, so either way i have to remove and put back each time i make your tests or somehow to hold it in hand while the pc starts and do tests u say.

Ufff right you are...that does make things more difficult....

I would remove that fan on the side for now and see if you can get all sticks out which wouldbe the best most comprehensive testing....

Or you could start and just go for setting the RAM up manually not XMP and see if lady luck is on your side...if you still get boot problems then you'll have to do things the long way...

Just be super patient and careful removing and installing heatsink....

But first of all i have to make the system to boot so i can get to the BIOS at least ...

Well i might not need to remove the whole cooler, just the right fan and i can get full access to the latest 3 kits only where i suppose it will be sufficient to make the tests, dont u think?

Yes and no...

Sure try to remove fan and see if you can get the sticks out....but remember that if you use one stick it has to go in a specific slot...if you use 2 they have to go in specific slots...so make sure you can get at all sticks....

And when you separate kits make sure one kit is on one set of slots and the other on the other

55890

So i guess the first stick ram putted on A1 doesnt matter if it comes from kit 1 or kit 2. Just have to figure out which of the one of the 3 remaining sticks is the pair stick to the the A1 so i can put to B1 and than the rest of 2 sticks to A2 and B2.

Well i know about dual channel. But as i told you earlier i think i messed up with the order of ram kits, meaning i do not know anymore which 2 of 4 sticks is the exactly kit. I have somehow to take a look on serial number or something if can see on the ram so in that way i'll know exactly which is which...

Arne_Saknussemm

Yes exactly....as i said you should be able to see this from serial numbers on sticker on side of RAM sticks...
