Hello all,

 

First post on these forums, love the videos on youtube!

 

So where to begin. I've been running an i5 750 with a gigabyte P55a-UD3r board, 8gb of ram and a gigabyte gtx 460 oc2 gfx card for about 5 - 6 years now and fancied an upgrade after reading the astounding overclocks that folk are getting with the new skylake cpus.

 

I ordered the following:

MSI Gaming M7 mobo

i7 6700k CPU

EVGA G2 1000w PSU

16gb Kingston HyperX DDR4 (2666)

Gigabyte G1 Gaming 980

 

Money wasn't available for the whole lot at once so a couple of weeks ago I ordered just the PSU and GFX card, which I slotted in to my existing build while I accumulated the rest of the dosh for the build. Fine. Everything working exactly as I would expect, no whine, no fuss.

 

Ordered the other parts which arrived yesterday morning and got set about building the new beasty. Everything went reasonably smoothly during install, up and running. Installed steam and fired up a game..... buzzzzzzzzzzzz - really quite loud. Oh deary me. First thing that sprung to mind was gfx card but how can that be since it was running fine on the old build? Shut down and installed my old faithfull gtx 460 to rule the gfx card out. Sure enough, as soon as I fired up a game - buzzzzzzzzzzz. I then tried swapping out the PSU to the old Arctic 700 and had the same thing. Pretty confused at this point and suspected something to do with power delivery through PCI-e port. Tried a different port - same noise.

 

Gutted, I resigned myself to the fact that there was an issue with the motherboard and stripped the PC down to RMA the board. I know that these processes are sometimes not the quickest so I re-assembled my old PC. 

 

Got reinstalled. Guess what noise still persisted? BUZZZZZZZZZ. Both cards doing this now on my old PC, which has been a faithful silent servant for years. Again, tried all combos of hardware, PSU, GFX etc. All to the same effect.

 

I've now opened an RMA request for the GFX card too. 

 

Could the motherboard have damaged my cards? Whats the beef yall? Anybody had any grief with the MSI M7 Gaming? Is my PSU incompatible with skylake? Im pretty gutted.

On a side note, used dabs.com for the CPU purchase - harsh email going their way as they saw fit to post a £300 CPU in a jiffy bag.... fair enough its in its retail box but seriously? A jiffy bag? The ram, in contrast was sent in a sturdy box with ample foam padding, a component that cost a third of the CPU (though ordered through novatech as opposed to dabs).
