Excellent instructions, from start ( downloading ) to finish flashed it only took 15 mins and all working fine !
I've started mining. Getting around 698kh x2.
This is at stock clocks.

Went through the whole process of reflashing again last night with the last BIOS.
It still kills my framerates from stock. It is smooth but no smoother from stock.
the graphs in Afterburner look different. The GPU usage are a lot smoother and not so many peaks or troughs.
What I dont get is at stock. My framerates in BF4 with everything on ultra at 1920x1200 are in the 120 130 range and the average GPU core use is around 50% (But the graphs in AB are a lot more choppy, fluctuating between 30-90%).
With the new BIOS My framerates hang in teh 80 - 90 range but fluctuate more and my GPU's are in teh 80% usage but steady fluctuating between 70-95% .
So it seems to me that the new BIOS decreases fps and uses a higher load in GPU.
I have checked and double checked. It is perfectly playable in either but the stock BIOS is smoother due to the higher fps. It is almost like having no bottlenecking from the i5 CPU as the GPU is running quite high now but oddly with less fps.
Have other 'FLASHERS' done a perfomance comparison in BF4 in particular? What changes have you noticed if any? Any thoughts?
Also I did ask if there was any other factors we had to use such as voltage - on reading further posts I notice the power slider is being used in AB. Is this a must? I see some people have AB upto 50% on this slider - How do I get 50%? I'm using beta 17.
I'm using W8.1

SHow me a screenshot of your afterburner settings.

My Fps is in that range but I run at 1600P which puts a lot more pressure on my system then yours

Just rename atiflash 4.17.exe to atiflash.exe on your usb stick!
Well I could have done that, long night.. Lol.
It works if you use the version of atiflash i recommend in the guide. If you use a newer version then you might have to alter the name as suggested above.
Fired up Bf4, Ultra settings, I'm not sure if it was the patch that was released today, which I doubt, or Ltmatt's Bios + settings but man is running Bf4 is totally smooth!, before it was jerking all over the place, stuttering and freezing every few seconds.
I've reduced the Volts to 1.75 already, Bf4 has been stable in single player for 30 minutes now, looking good! Best program to test volts, Heaven perhaps?
Matt I owe you a beer!
I really hope this coil whine quietens down a bit, would be ideal, I think I can live with it but if I sell the card on will the next person..
I didn't expect such a smooth experience with my dated i7 930 @ 3.8 but it seems to be holding up!
Best way to remove tearing without using Vsync, anybody?

I spoke too soon. For some reason since restarting my computer bf4 has turned laggy. If I put bf4 into a window, and drag any other windows on the desktop around they are choppy, missing lots of frames.
Assasins creed runs the same, really bad!
Im not sure what happened!
Update : Exited out of Afterburner, ac and bf4's framerate went straight back up!
Afterburner's causing some issues here! (Latest beta)

Crossfire only works in full screen mode so that could explain the problem. Not noticed any issues with afterburner myself, but it is possible and has been known before.

Cheers for this, all updated and working now. 
GPU usage on both gpus ranges from 55-80 or so when playing BF4, suprised that a 3570k must bottleneck it?
It's buttery smooth at 1200p on ultra so I could care less though.
Edit just checking your crossfire thread to make sure I've done everything possible. I don't have any of the options for ULPS or enabled crossfire?

Use IMGUR next time mate. Embed the image on the forum. Its quicker and easier for you.
Set unofficial overclocking mode to disabled. What cpu have you got?
Things look pretty good there in your screenshot. Have you tried under volting the card a bit? 1.200v is generally overkill for 1000/1500. Try 1.1785v or even 1.150v, or even lower.
What was the problem exactly?

An i5 will hold back a 7990 in BF4, but if its all smooth what does it matter.
Mantle may cure your cpu bottleneck entirely though.

Any help with the edited image above? Just making sure I get the maximum performance. Got me looking out for a 3770k in the MM now.

That's because your MSI afterburner is older than my brown and yellow poker dot y-fronts.
MSI Afterburner Beta 17
Settings should look like this for optimal performance.
