I'm usually one of those people who will sit and work it out for myself, but this has got me stumped.

Well in my 15+ years in IT (and I was a Apple certified tech too..lol), I seriously have never come across personally coil whine in a GPU until I bought the GTX780ti's.
PSU yes.
My systems have always been overclocked and stable, no annoying noises, and for the life of me now I don't know why the run of bad luck with the GTX780ti's.
Stick my ASUS GTX670 single or Sli back in the machine, no whine but a GTX780ti there is whine.

Don't get me wrong this Galaxy GTX780ti HOF has been the most stable, coolest (temps) and fastest out of the 3 cards I had, and I can't praise it enough, but the whine.
Its a good thing it matches the frequency of the fans, but bugs me when I know what I'm listening for, can't help but stick my head on the side grill (Bloody OCD..lol)
I'm at the point of buying another PSU, wife will kill me though but I don't know.

After reading a few forums, its not an unusual thing just all the miss information.
Loved the one that said GTX780ti's don't have coils doh.gif

You have been a great help Ed and very patent, Thank you. thumb.gif

All that stuff with super overclocking and then mining isn't really worth it, I would get around with luck 50-60 khash more and that is just not worth to be without a card for a few weeks again for that little

You can easily get to 1085MHz @ 1.085V below 90C.
The total gain over standard non-SC model is about 100Kh.
Also remember that you can RMA the card directly with EVGA, no need to go via the retailer.

Regarding some of the power components, I notice that inductors are a common part to fail due to overheating. There is also no TIM between them and the heatsink. This seems like a major oversight, and easy to rectify.

My MSI gaming is not a dud but it's not great either.

With regular skyn3t bios I can do 1250s in Crysis 3. Now NFS rivals can only do 1140 to not get that horrible "get device removed" error. BF4 surprisingly does higher but I haven't tested it yet.

Hello guys! Since last posting I have RMA'd my Gigabyte Windforce (one of the many defective ones out there) and was refunded accordingly.

Today I've received the EVGA 780 Ti SC ACX and what a difference! I've already started playing around with overclocking it with the default BIOS and it handles it very well. This is very stable at the moment:

Could I ask for the person in charge of the owner's club list to remove my Gigabyte entry of March (the 21st)? That poor guy is probably being disassembled as we speak...

True! Most inductors used in graphics cards are rated at 85C, although they can withstand higher temperatures,
thermal fatigue is a threat in any composite system that experiences thermal cycles during use, EK in the Titan/780 early water-blocks assembly instructions "forgot" about the [R33] inductors thermal tape but redeemed themselves when released the 780Ti blocks!
Its amazing the quantity of overlooks these companies make... rolleyes.gif

Yeah. I might take the HSFs off my GK110 cards this weekend and fit some thermal pads between the inductors and the heat plate.

Did you flash it already? Send me your stock bios to check it! thumb.gif

When i bought my 2 EK XXL blocks, i put thermal tape on the memory inductors even when there was no indication to it, i found it strange that there was thermal tape on the core phase inductors but not on the memory, later on discovered it was an oversight on EK part!
Quite a few titans "died" from memory inductors failure, directly caused by this oversight or not i cannot really tell... rolleyes.gif

And others..lol

What would you do in my case, buy a new power supply (recommendations)
or get a better case that doesn't have open mesh grills on the side (Was thinking NZXT H440 plenty of sound dampening).

Thanks again guys.
