D.F.I 790FX-M2R 12/21/07 Beta Bios Findings
The Good:...Ok, heres my thoughts on this Bios from testing it out, what I come to find is that the 12/21/07 Bios Clears up a lot of little annoyances such as USB Keyboard Lock ups in Bios, Less C1 Error then all previous Official and Beta Releases also allows me to achieve 40mhz higher HT on Overclock and excellent Ram Bandwidth and very low latencies with less Vcore & Vdimm used compared to 11/22/07 Official Bios also it appears the HT 600MHZ setting is working better as well. Smart Guardian is reading Temps more accurately too and Bios displays correct CPU Temp in Bios now which coensides with Core Temp and Everest/ on the Downside Smart Guardian is still way off when put under load like 20c off from Core Temp / Everest
The Bad: there is some form of issue when in Bios and you load Optimized Defaults so you can start with a clean slate and configure you're settings once again. By Loading Optimized Defaults and then Configuring you're Overclock Settings Immediately after loading the optimized defaults then Save / Exit I got what appeared to be C'mos corruption when it rebooted something I had never seen before ever on any board which was a Bunch of small Random moving Colored Grid squares (thats not cool) and shortly after that I started getting allot of C1 Errors and Random IRQ Address Allocation on my Raid Controller and what that means is that at different reboots the Raid Controller FW Bios would show different (Bus Device #) as well as Different (IRQ Addressing Assignment Adressing #)
I also notice that with this Bios using anything after 2.16Vdimm it does not want to play nice to any degree more VCore and other Voltages applied it did not matter!
Their is also what appears to be a issue the Weak Ram Drive Strength setting as that does not seem to be working correctly compared to 11/22/07 Official
Edit: Also I forgot to mention there is a slight Refresh Issue when Going into Bios with the New PCI-E 2.0 GFX Cards I have confirmed this being Fact with 2 X POWERCOLOR HD 3850's Running in CrossFire as well as it being duplicated with the Single HIS HD 3870 GFX Card. This issue is not present with my XT1950 XTX
Apparently there are still issues with AMD Overdrive and this Board as well even on Current 12/21/07 Beta I still get Lock Ups just by opening the Program this is with Optimized Defaults set in Bios too! I don't quite know where to point the Finger at that one whether its a Bios Issue or on a Software Level or Both.
So if any of you gents could confirm any of these findings that I have just mentioned Especially the Load Optimized Defaults in Bios and Immediately after that re configure you're overclock Save / Exit and see if its a issue beyond my experience we could really help this along with some hard info to submit to D.F.I so we can get a really Stellar Official Bios Release in a Timely fashion.
Thank You.......................Campbell
