Based on your BIOS version, looks like you have got an Engineering Sample machine. If my memory serves me right, you can use the blind flash to force update to production version. I would suggest to start from an earlier version like A07, then up to A13.

Most likely your memory stick(s) can't sustain the higher speed. Are you using the stock memory from Dell or after market memory sticks which designed for o/c?

Could someone be so kind to provide the link to non-oc 780m VBIOS? The version I am looking for specifically is 80.04.B3.00.10 TIA

WEI is removed from Windows 8.1

svl7, hope not bothering you too much regarding the same question. Will you release A13 unlocked BIOS for M17x R4?

Both A11 & A12 BIOS should have no problem supporting GTX 780m

Upgrade to 780m does not require unlocked BIOS, just do the following: 1. Uninstall nVidia driver 2. Replace MXM module 3. Install new nVidia driver (might need modded INF)

svl7, will you release unlocked version for A13?

Mine is M17x R4 with self upgraded GTX780m, I got 4521 with 3940XM, no CPU/GPU oc.

svl7, will you release unlocked A12 as usual? TIA

Thank you Mr. Fox. I did the upgrade, took me around 30 minutes or so. It is very easy to remove the front bezel, put it in M17x R4 takes most of the time. But it is a smooth job nevertheless.

Panasonic UJ-265 price has dropped to a point I consider affordable. Has anyone had any experience in upgrading their Alienware laptop to a BluRay/RW? Is it hard to remove the front bezel of UJ-265?

I am thinking of upgrading to Win8. If using Win8, I would prefer to change the BIOS from legacy mode to UEFI mode to speed-up booting time. In UEFI mode, will all the changes I made in BIOS (advance settings) stay active? ex. disable built-in Intel video, boost turbo setting for 3920XM etc.
