Bios Testing ........D.F.I is Back!For those of you that know me you are aware that my primary role on the Debugging the Phenom /790FX Platform has always been in the Bios Department and we are also aware of the constant Bugs that have Plagued the AMD Platform from all Board Makers since the Initial Launch a Year and a Half ago of Phenom and the 790FX Platform. Well since the original 790FX SB600 Release there has been a major improvement in Bios Development form D.F.I and also a major contributing Factor to that has also come from AMD themselves through AGESA Capsule Update and Micro Code Updates over the past year and a half. The Bios that I have been testing for D.F.I for the LanParty DK 790FXB-M3H5 have been nothing short of Brilliant Bios Programming Workmanship!
I have to admit The Bios have been nothing short of Rock Solid and Stable and of the Old NF4 Days Quality......Yes they are that Good! So far I have been testing Three Bios for this Board the 3/06/2009 "Official" Bios and the 4/15/2009 & 4/24/2009 "Beta" Bios and I have searched and searched but I have yet to find anything wrong to any degree no matter how insignificant on any of these Bios that I have been testing.......Way to Go D.F.I:clap::clap::clap::clap:
I have taken the Time to Compile a List of DMM Read Outs for the CPU / NB Voltages Idle and under load with OCCT High Priority for testing and all Voltages have Been double checked for consistency and accuracy!
All Voltage Measurements were take with a FLUKE 179 Digital Muti Meter and the Grounding Source is from the Black Wires on the P.S.U itself so if any wish to test for Voltage read out it should be grounded to the P.S.U not the Motherboard Screws as the Motherboard screws or any other location other then the P.S.U will give a inferior read out.
All three Bios DMM Read Out Lists are taken to more then reasonable levels of voltage for most users that will either be on Air or Water Cooling any further unless on Phase Change or LN2 , DICE would not be advisable!

ALL DMM READINGS HAVE BEEN DOUBLE CHECKED FOR CONSISTENCY & ACCURACY & BOTH IDLE & LOAD! As we can see through the DMM Readings the Bios Overvolts when Comparing the Readings on the Charts for what Bios & Smart Guardian are Reading.
These Readings for for DMM on any particular Bios will differ for each CPU & P.S.U which will also have a impact on DMM Read Out. When speaking with Oese who is running a 955 BE and also Testing this Board and Bios with me for D.F.I Taiwan his readings are pretty much Spot on with DMM Read out for Voltage set in Bios so once again things will vary dependent upon which CPU is being used on the Board but Bios and Smart Guardian Read Outs are consistent with what I get on my end . So as we see that needs some adjustment in future Bios Releases to re calibrate Bios & Smart Guardian to be a little more accurate to actual Voltage set in Bios.
These DMM Read Outs have all been forwarded to D.F.I Taiwan where the Bios Engineers will use these Reference Charts from me to make the necessary adjustments to the voltage table for this Particular Processor. As I have stated I have looked high and low for Bugs and inconsistencies in these Bios Releases and have yet to find or have a complaint to any degree on any of these Bios Releases other then what I have mentioned above which is being worked on right now by D.F.I Taiwan.
If this is any indication of what we can expect to see in up and coming Future Bios Release I will say that we will be seeing some very serious and Impressive Bios Work from D.F.I for their New AM3 Series Motherboard Line Up!
