Hi, 

Are you able to access the Boot Menu with the F12 key? If you are, try running the ePSA/Diagnostics test and let us know if you receive any errors.

Look through my Favorites for flashing BIOS from bootable USB-Flash.

Also, to get from A04 to A11 ... you should have used a stepped (about 3 BIOSes) approach.

Thanks for the replies, I made progress before I could check back here. I forgot to mention I was upgrading the memory as well. With the A04 BIOS the new memory worked fine. Windows booted and all seemed okay so I left it in during the BIOS upgrade. I decided to swap with the old memory this morning and it boots! 

This is the memory in question - 2x 8GB Corsair DDR3 2400MHz 

So now...why does the memory not work with the new BIOS. I'm going to start messing with frequencies, timings, etc to see if I can get it to work.

Also...I downgraded the BIOS back to A04 but the new memory doesn't work now :C This computer is a serious pain in the ***. Perhaps I should try doing the stepped upgrade to A11 like you mention?

2400 won't post; try 1600, if ok, try 1866 which is max speed, xmp off in most cases.

Multiplier / ratio is normally 133 * X > if X = 12 (then 1600) if X = 14 (then 1866)

The only problem with this is that I can't actually get into the BIOS with the new ram installed. The loading bar goes to about 3/4ths and pressing F2 at any time does nothing. It recognizes the keystrokes but nothing happens. Which is really weird because earlier on I could get into the bios with this memory...

That is a helpful post though. Perhaps with different settings I could have made it work differently. I'll explain what I had to do below though.

I found solutions to both my problems via much trial and error as well as a helpful forum post on these forums.

Problem: Windows (10 64bit) attempts to boot with new CPU installed but throws a WHEA_UNCORRECTABLE_ERROR and reboots

Solution:  This is a weird one but it works. Increase the QPI Core Voltage to +40mV or more. The PC boots and is rock solid after doing this.

Problem 2: With new memory installed, the PC freezes at post. 

Solution 2: Take known working memory and put into DIMM1. Take new memory and put into DIMM 3, 5, 2, 4 ,6 in that order, depending on how much you have. Important! Any pair of slots (1 and 2, 3 and 4, 5 and 6) cannot exceed 8GB of memory. 

I must note however that the Corsair Vengeance would not work with the QPI Core Voltage increase. What I ended up doing was swapping it with 2x 8GB 1600MHz modules from my own PC and while they still would not allow the machine to complete post, I was able to find a configuration where they were happy.

And onto my last and hopefully more simple problem. Ever since the BIOS update the fans run at like 100%. I reinstalled the Command Center and it worked fine, until I rebooted, and they went back to 100%. You can control them manually via the Command Center and setting them to Auto sort of works but they just revert to max speed after a reboot. It's version 2.8.9.0.

1866 memory is the max I would recommend at 12G.

Aurora-R1 * Six memory slots (2/1,4/3,6/5) * Matched memory modules are installed in DIMM connectors 1/3/5 or 1-6 *

To run in Tri-Channel mode (3 lanes), memory must be installed in multiples of 3 * Maximum memory 24GB (1067MHz and 1333MHz) or 12GB (1600MHz XMP) * For PC3-12800 and PC3-15000 XMP memory, go into the Bios and turn on XMP.

Go into the Overvoltage Config and set QPI and Uncore voltage to +200mv. Leave everything else on Auto

* Dell Part numbers - R1HVP 2GB, 1866MHz PC3-15000, 256X64, XMP 0TDWJ 4GB, 1600MHz PC3-12800, 512x64, XMP 0PV61 2GB, 1600MHz PC3-12800, 256X64, XMP 5DX3Y 2GB, 1600MHz PC3-12800, 256X64, XMP H345K 1GB, 1600MHz PC3-12800, 128X64 P382H 4GB, 1333MHz PC3-10600, 512X64 P223C 2GB, 1333MHz PC3-10600, 128X64 1N7HK 2GB, 1333MHz PC3-10600, 128X64 TW149 1GB, 1333MHz PC3-10600, 128X64 N852H 4GB, 1066MHz PC3-8500, 512X64 Y996D 2GB, 1066MHz PC3-8500, 256X64 F680F 1GB, 1066MHz PC3-8500, 128X64
