Edit- I noticed my WEI went down on cpu under the "Balanced" power profile from 7.9 to 7.3. I changed the profile to "High Performance" and it went up to 7.5. I don't put a lot of stock in the WEI score, but maybe someone can run a CPU benchmark showing a before and after to see if there is indeed a change.

 

I think it was 7.3 before and not 7.9. 7.9 is max score it can get for cpu

I think it gets hotter easier and works aroun 2.3 ghz on full load(8 threads) because of temparetures.It did go up to 3.2 I think (not sure if I saw 3.3) and after 10 minutes stabilized aroun 2.3-2.4ghz

 

Just ran a new assesment of WEI.CPU went from a 7.3 to a 7.5

(Confirmed that before it was 7.3)

 

Has A08 been pulled as it cannot be downloaded?

ALthough I think new Dell support site is just broken as it doesn't really allow downloading anything but gives "File not found". Tried both EU and US sites.

 

I just checked and it's working for me now. Here is the direct link to bios A8 for the E6420:
