Crosshair V Formula-Z RAM Bug?

Hidden
Level 7
Hi,
at first sorry if my English isn't perfect, it's not my native language.
I'm a loyal Asus customer for ages but right now I'm really considering switching to an other brand.
It seems like the problems with my Crosshair V wont come to an end.
The first one I ordered made an extremely annoying noise like a kettle whenever the PC was idle. Disabling C6 fixed this but it still annoyed me that I had to disable an energy saving technology so I returned it and got a new one. The new one makes the same noise but a lot less annoying, I'm still not completely satisfied with this but I can accept it.
But also my RAM is making problems. When I insert the RAM that I used on the first board the board will stuck with q-code 50, but even if I take this RAM away or insert different RAM it stays at q-code 50 until I unplug the power supply and use different RAM. It works with the RAM that was intended for my HTPC but I can't get it to work with the RAM that was intended to use it with. The RAM is NOT damaged, it works in my HTPC as it should and it worked with the first board.
The second problem: Yes, it works with the HTPC RAM but it's totally messing with the frequency. The UEFI says 1600MHz and CPU-Z shows 661MHz, both is completely wrong, it should be 2400MHz which means CPU-Z should show 1200MHz. I'm not sure if the first board would have had the same bug but CPU-Z showed the RAM that isn't even working now with the correct values (PC3-12800, 818MHz) which are already higher than the PC3-19200 RAM I'm using right now.

So, am I doing something terribly wrong or is this board damaged as well?

regards,

System:
Board: Crosshair V Formula-Z
CPU: FX-8350
Graphics: Vapor-X HD7970 3GB
Ram that works: Kingston HyperX Predator XMP PC3-19200U 2x4GB
Ram that doesn't work: G.Skill Ares PC3-17066U 2x4GB

OT:
I know this is an Asus Forum and all of you are happy Asus users but if I have to return this board as well I'm pretty sure I will buy something that isn't called Asus, so for the case this is necessary, any recommendations? (something that doesn't sound like a kettle would be grate :p)

OT2:
The registration for this forum really is a pain in the ass, it told me I was already registered when I tried to register and wanted to upgrade my account but wouldn't continue and it told me my password is wrong ... It took me about 15 minutes till I finally tried to log in at the login boxes at the top right corner and suddenly the exact same upgrade site worked and the exact same password was suddenly correct :confused:

Welcome to the Republic of Gamers forum, Helidan.

I don't think the kettle sound is coming from your motherboard. And since you've changed it for a new one and the sound is persisting, that makes me think that it's another component that's causing it. The heatsink, PSU or GPU are good candidates for this kind of thing.

As for your RAM, in which slots are you installing the two modules? Make sure you are using the red slots and they are seated properly. The motherboard is showing the QCODE 500 because it is having problems initializing the memory. If you're stucked at that QCODE again, hold the small Go Button for a few seconds and the LED should start blinking and hopefully when your motherboard restarts, your memory should be trained.

As for the frequency, all the high speed kits defaults at 1333MHz. To get it to run at 2400MHz, you'll either have to set them up manually or use the D.O.C.P. feature that comes with the CHVFZ. And on a sidenote, not every FX8350 can do 2400MHz. Just a friendly warning to save your some hassle. 😛

Ok, no idea why, but the RAM suddenly works. I plugged it in to try some things and it worked without me doing anything :confused:

No, im 99,9% sure it's the board. I switched the GPU and if the PSU would make the sound it would come from a different location (from the PSU itself, but the sound doesn't come from there). The sound is also still there when I stop the only fan of the heatsink, CPU and RAM simpy can't make such noises and SSD and HDD aren't influenced by C6, therefore it has to be the board. (The sound disappears as soon as the PC has to do something. Moving the mouse is enough, but as soon as I stop the mouse the sound starts again and so on)

Ok, I actually missed that the CPU doesn't support anything higher officially. Still, I can't even get it to run with the maximum supported value. Using D.O.C.P. and a RAM-predefined 2133MHz profile results in q-code 50, using the available 1833MHz profile results in q-code 79 (which doesn't have to do anything with RAM as far as I can tell :confused:)
The maximum frequency I can get to work is 1600MHz, it's not really a big deal but still bugging me 😞

First of all I am sorry to hear about your problems.

Second the ram is not about the motherboard, it is about the CPU you are using I think. As you know the IMC is on the processor and the motherboard technically has very little to do with the ram. I wonder if you swap out the CPU to the other board is the ram issue still present or is the ram issue gone.

And lastly - this is one of the very few times I would suggest that a flash of the bios might just be useful as a fix. But again I am sure you have tried that.
To help us help you - please provide as much information about your system and the problem as possible.
