Corsair Vengeance RAM emitting odd noise?

[August K]

I'm almost 100% sure the noise is coming from the RAM, I tried running my fans at max speeds, I tried turning them off completely, HDD is too far away from where the noise is coming from, so it can't be the HDD... It must be the RAM then, but I'm not even sure if RAM can emit any kind of noise to begin with. The weird thing about this is, that the noise is only being emitted while I'm specifically in-game of 'warframe', If I alt-tab it goes silent, if I shut the game down, it goes silent, whenever windows are booting up, there's no noise either, whenever I play other games like battlefield 4 or crysis 3, can't hear the noise either.

Note: all of this started happening today, this morning (26th of October), yesterday it was fine No windows updates were received before this started happening, I've actually re-installed windows to see if that would change anything, no hardware was changed or anything, I also did a memtest86+ and no errors came up, I have no idea what the hell is happening, but it started happening out of nowhere...

-Edit: Now RAM seems to be emitting noise whenever playing other games as well, not as clear and loud as warframe, but I can still hear it. Alt-Tabbing still shuts the noise down.

No moving parts on ram so very strange! I think it is something else.

they make a sort of 'buzzing' noise, kind of like electricity

Coil whine it is called. It is possible but would be very rare, more likely from the board, have you tried removing one stick at a time or reseating them.

May just want to see if you can borrow another stick or 2 of DRAM from somebody and try, have a feeling it may be the mobo, your CPU cooler or the like nearby

Ok, I tried to run one stick at a time, and I still had that same noise. So now its either both RAM sticks or something else?
what is coil whine btw? what causes that and how damaging is it?

Ah, ok I've looked up some videos about that, I kinda get it now, but the coil whine shown in those videos is always this high-pitched squeaking noise rather than what I have, which would be a more of a high frequency buzzz sound.

However I did notice that the pitch of the sound my PC makes does change depending on what parts of the level Im looking at in-game

GPU maybe

GPU maybe

that's what I'm thinking atm.

I have an Asus GTX 780 fyi if that helps.

-Edit: while fiddling around in my nVidia control panel with V-Sync options the noise seems to be lower frequency now, I can barely hear it, but it's still there, and it wasn't there yesterday... Is that normal for this 'coil whine' noise? To just appear out of nowhere?

 

[August K]

By the way, I found out that there are things called intel C-State and C1E support that have something to do with this, (apparently that is tied to motherboard coil whine) should I disable both of those features?

 

[rolli59]

GPU's it is rather common today, seen many complaints. I do not know what those states do but you can always turn them on again.

 

[August K]

well, thanks for the help, both of you. I'll see what else I can come up with to reduce the coil noise as much as I can

Give us an update when you get it figured out for sure 😉
