complex questions touching on many topics.
 
So, in no particular order.
 
1. Coil whine indicates that you are pushing the vrm on your card.
Sometimes it dissipates with time (break in period) sometimes it can be alleviated by reducing your OC...or when running a 24/7/365 program like folding actually under-clocking.
While annoying, and an indication of high load, it usually does not cause any damage/indicate a malfunction.
If it occurs when gaming and is a real annoyance, most companies will however consider it cause for an RMA
 
2.What is the Advanced method?
 
PG has a process for rolling out their WU. They test internally, then allow limited beta testing and finally roll out to everyone. Sometimes WU fall between beta and roll out due to excessive requirements (CPU cycles, memory requirements, large upload or download bandwidth, etc. etc.) and are considered "advanced method"
you can select to receive the type of WU you want by setting flags. BETA OR advanced method.
 
3.I am getting core 15 after core 15 and not really earning much for them.
 Is this happening to everyone?  What is the Advanced method?  It is not worth the burn on my computer to continue to run these cores non stop.
 
PG prioritizes their science investigation over software support. Consequently, there is often a lag (months to years) between new hardware architecture(Maxwell), drivers(Nvidia), software(Open cl Open MM) and optimized projects using that software to investigate science(FOLDING CORES)
 
The irony is that very poorly optimized software can cause very heavy loads on just one part of a general purpose gpu. Since the compute functions of a GPU are designed to support the overall GPU (gaming..etc) they are not really designed to run flat out 24/7/365 without pause. This is what you are seeing with core 15. It does a small amount of science, but puts a very heavy load on one specific function of the card. (like running one cylinder of an v8 at 10, 000 rpm rather than the entire engine at 1250rpm)
 
So, the old WU(core15), that under-utilizes the potential of the GPU...is currently the default.
 
In time( or in theory), you should see this type of high load WU moved to advanced instead of default.
 
Should you continue? Up to you. PG indicates that they want to complete the core 15 projects...although they have been universally unpopular...and they(PG) have refused to either update the software or the adjust the points to make them more palatable to donors.

Core 15 was after all never EOL. Back to mining until this gets resolved.

Why not run BOINC for now?
Mining is for Money Only.

In a way, sure it is. In another way, it's a lot more than that.
 
I'll just let my 5820k fold for now.

" it's a lot more than that"   Like What?
 
I do Bitcoin Utopia sometimes but they keep the Coins. This is also on BOINC.

Please support us in getting the OpenCL performance driver bug fixed and post in the nVidia Forum to get nVidia´s attention:
