My XPS 8300 has the usual A06 Bios. I'm using an i7-2600 Sandy bridge processor in the socket 1155. It appears that with an upgrade to Bios A07 it will run an i7-3770 Ivy bridge processor in the same socket. Dell UK official support says no, but the A07 bios is available on the USA support site. Has anyone tried this and does it work? You have to remember that it is not in Dells interests to help you upgrade old computers, they don't make any money from it, they want you to buy a new one. They told me that I couldn't upgrade my Dimension E520 from a pentium D. But I upgraded the Bios to V2.4 and it is happily running a Q6600 Quad processor!
The USA XPS 8300 driver page only shows BIOS A06. Dell never officially released BIOS A07. Where are you seeing it?
Firstly, many thanks for the reply, appreciated. The A07 Bios on the USA support site is of course the Dimension Bios not the XPS Bios. As you say Dell never officially issued the XPS A07 version, although there are some refurbished motherboards with it and some unofficial copies floating around.
This was an exercise in possibilities. Firstly could I get a copy of A07, next would it support Ivy bridge processors, and lastly could I get an i7 3770 for a sensible price.
Hacked A07's are around, but it is reported that they don't support Ivy bridge. Next, UK Ebay has i7 3770's for £40 ($53) had it worked that might have been do-able. As you say $380 for a new one is just silly.
But the A07 microcode apparently only supports Sandy bridge processors so that is that. My rig has an uprated PSU and runs a GTX 1060 3Gb card. A modest tweak to the chip was thought to be a possibility.
I still run a 12 year old E520 with a GTX 750 card. Old Dells are solid work horses and excellent value for money, I have 6 of them. It's just a shame that Dell offers limited upgrade options. i.e. the motherboards are Intel to Dell's specs and are locked. And there is no reason why the A07 Bios wasn't released if refurbished M/B's have it. In fact it still could be released today with an "at your own risk" label as not fully tested.
