Hello guys :)

First of all sorry if I didn't make any presentation topic, forgive me for that. :(
I'm mainly signed up here in order to collect as many information as I can to solve my issue.

I bought a Gigabyte GA-Z77X-UD4H matching an Intel i5-3450 Ivy Bridge. To complete the rest I also bought the RAM as well, a pair of Crucial Ballistix Tactical Tracer 2x2GB kit (DDR3-1600 - 1.5v - 8-8-8-24), or to be brief, 4x2GB total. My bad surprise comes out when it was the time to turn everything on: no boot, or to be more detailed, boot loop.

Fortunately my aid is the Port 80 Diagnostic display. It states before the restart the POST code 96 (Assigned PCI resources). Sometimes it gives me the code 51 or 53 related to the PCI resourced, maybe.

I tried to boot the motherboard with 2 sticks of DIMMs, and they work in dual channel, but if I put a dimm starting from the third slot or I fill them with all the four modules, the system won't cooperate to boot, so black screen and the boot loop infact.

I did the following cross-test:
Try to see if the bent pins are all ok (they're ok)
Try the rest with a different PSU
Unplug every peripherals excluding the video card, eventually
Updating both UEFI firmware (from F1 to F2H)
Put the ballistix kits in another mobo (both of them work at the first shot with a Asus P8P67-Pro)
Start the system with different DIMMs (Corsair Vengeance LP 2x4GB. It even work when I mix that kit with the crucial ones and no issues)

I don't know if they're "hunger" with voltages or some settings related to mobo (even because this is my first encounter with UEFI system :( ) but eventually is there any solutions before RMA or replace? Someone said to lower the voltage from 1.50 to 1.30v and see what happens, or another theory is an eventual CPU-stressing and lower the CPU voltages as well... So before any harmful steps I just want to know what should I do. I'm keeping in touch with the Crucial support forum awaiting for a reply from them.

Sorry for this request guys, but I'm a bit upset for that :( Be gentle with me even with my english... Is not surely perfect but I do my best to be clear in what I want to say... :)

Hi,

Try this,


Put two RAM sticks in, boot up, set the XMP profile for the RAM to work at correct speed/timings+voltage.

Power off.

Fill all RAM and power back up?
 
I even did as you suggested but without any results: over the third DIMMs inserted, it happens the boot loop :( for correct speed/timings/voltage is everything normal, probably the UEFI set everything for its own...

Anyway the DIMMs are 1.5v, CAS8 (8-8-8-24) at 1600.
I tried to fill every slots with the same results...
 
It's not harmful, but you may get errors as the RAM will be specified to need a certain voltage to run at a certain speed.

To be honest I think its a board-RAM compatibility issue.

This isn't the first time Ive read about Crucial Balistix RAM and a Gigabyte board having issues.
 
Ok, flashed one of the two UEFI to the newest version, later i'll do this attempt and see what happen. :) Already setup the XMP profiles before.

I just want to know this about the DIMM voltages because It's not pleasant to fry something in order to make the board-ram compatible at 100% :D as I said the DIMMs work well into a P8P67-Pro, so it's mainly a board issue or that modules are not stated in the QVL list... It happens.

I'll keep you informed once I set the modules up, following the procedure you wrote ;)

EDIT: I tried to do some test testing the kits singularly. I think I finally found the cause. I inserted a kit in the two DIMM slots for dual channel and it boots without issues. Later I picked up a module from a kit and another one from another kit. Guess what? It doesn't boot!

So if I pick the good modules the system boots. The other one don't... Probably a kit is faulty... Would it be possible?

ram can always be faulty, but most ram these dasys have a lifetime warranty.
download program called memtest, run that from system boot, if ram faulty it wil show up on that test. if no errors, then you can rule out the ram as problem then.
 
Ok, I'm doing the test. Another thing is strange... Initially the system stop at the post code 15 for 10 secs or more... Then it reboots and the ram is working back. Now I seriously think that these kits won't cooperate toghether and one of them are probably faulty to boot... But it's strange, the two kits runs smoothly in another system.

So my suspicion it's focused on the motherboard/cpu and the RAM...
