I will have to do some reading up on the dual bios. F9 does not seem to work on this motherboard. Specification says it supports the following:
Support for @BIOS
Support for Q-Flash
Support for Xpress BIOS Rescue
Support for Download Center
Support for Xpress Install
Support for Xpress Recovery2
Support for EasyTune (Note 4)
Support for Easy Energy Saver (Note 5)
Support for Time Repair
Support for Q-Share
F9 is Xpress Recovery but it requires you to boot with a cd and driver disk from Gigabyte!
For virtualisation I use KVM on Ubuntu Server and Desktop using Virtual Machine Manager and Cloudmin. There is virtually no difference in performance between the KVM VM and bare metal. A lot easier to use than Xen and with full Red Hat support and development probably the safer longer term bet no special kernels, builds etc. as KVM is integrated into the kernel. I use webmin/Cloudmin to manage the systems.
All seems to be running well with the L5430, it is the same generation of processor I have in a number of dell servers (L5410 L5420) I just need to understand the thermal envelope and tweak power settings etc. It seems to run a lot warmer (50 Deg C) than the Dual Cores approx 10Deg C warmer using the same cooler etc. Maybe I need to have a look at the thermal paste and ensure I have good contact. I use an Arctic Cooling Freezer 7 Pro Rev 2 and have found it to be awesome. I could OC a E5500 to 3.3-3.6 Ghz comfortably on this board and cooler combo.
I cannot get the speed above 333mhz x 4 so there is no tweaking available for this processor just 8 x multiplier on this board. I would be interested in others experience of using this processor (thermals, clock settings etc.).
Just a footnote. Both the G41 Chipset MT-D3 and the MT-ES2L boards are essentially identical in specification. I can't find any differences at all apart from the capacitors, it looks like the D3 board is the later board, a good reliable board though and a very cheap Xeon platform
EDIT: It seems that lmsensors and the gnome senosrs applet are over-reading the cpu temp by about 20 Deg C. When I look at the CPU temp in the BIOS it shows as about 21-25 Deg C and in Windows 21-25 Deg C but in Ubuntu using lmsensors it shows as 45 Deg C +.Edited by sparticle - 3/16/14 at 11:32am
