You know pretty much that I am still agressively pursuing a BIOS for my M4A785TD-V EVO that allows me a broader range of undervolt, so I can boot at very low Voltages that would allow me to safely attempt to run my machine with passive cooling. My AIIX4 620 Deneb RB-C2 is fully stable with CPU 1 GHz @ 0.8V and IMC 1.2 GHz @ 0.9V during extremely long both Load and Idle periods.
I'm using the BIOS 2002 (There was a BIOS 2005 available quite a bit back but the changelog isn't compelling, seems to be released for PIIX6 support) that just allows me to undervolt for a maximum of 0.3V the nominal Voltage of the CPU and IMC, but I need more than that. This would allow me to not need to use k10stat for undervolting under Windows and just boot at the settings that I want to.
I also noticed that while the current BIOS possible undervolt works properly from the supplied Voltage perspective (Motherboard VRM I suppose), it doesn't update the VID value of the Processor, meaning that if I use CoreTemp or k10stat that reads it, they think that it is running at nominal Voltage when it is really running with a -0.3V offset. CPU-Z does recognize supplied voltage quite accurately (Though slighty lower than choosen Voltage or VID, even on nominal conditions). I don't know if other Motherboards BIOSes makes the Processor aware of VID value for properly reading by CoreTemp, but most importantly k10stat.
Anyways, you know that I am looking for news on this. This is my fourth ASUS Motherboard (I only builded one computer for my cousin that didn't had an ASUS), so as a customer I DEMAND SATISFACTION!1!1!1
Thank you.
Downloaded and installed 0905. No problem with installation, and just starting to play with settings but still have problem with CPU speed not reducing with C & Q enabled if I raise multiplier above 18.5 for CPU. All other CPU settings are on auto. I have been raising the Turbo setting at +1.5 of the cpu setting but I have also tried turning off Turbo and other settings for Turbo. This appears to be a problem with the CPU multiplier.

ROG Connect shows same behavior as Everest and CPUz voltage reads.
CPU/NB voltage also changes from 1.3v (Bios) to 1.33v, not so bad as CPU does.
On RC TweakIt panel CPU voltage turns red above 1.5v to 1.58v max.
LLC on @Idle - CPU 1.59v max (Bios: 1.4v)
No LLC @Idle

Sorry for the delay, been traveling today. I will setup a system tonight and test 0905 that was released this morning. Unfortunately, I was not able to test this release before I sent it out (bangs head on table for not following personal routine). Any problems with it will be addressed by tomorrow as R&D had an early wake up phone call this morning.
With Turbo enabled the CPU voltage will fluctuate with the change in the cores multipliers. LinX would load all cores so there would be no voltage change because of Turbo. 1.60V is a bit high though with 1.40V set. These voltages really need to be validated with equipment instead opf software.
So... no M4A79 (without T) on the list yet?
edit: in ref. to crosshair IV formula:
im having problems booting into windows on 0905 at >1900mhz memory c7 or c8 - 0801 i was running superpi 1950+c7 can anyone test that when they get a chance? not sure if its something on my end or not
also, bingo13, when using single gpu, pcie1 (top slot) is the only slot that offers x16 link width?

In order to expedite the replication of any problems with BIOS 0905 on the C4F that have been reported today I will be sending a PM to you for some additional information.
Some additional information based on testing tonight.
1. C1E/CnQ options not available when setting CPU VID to manual without offset. This is actually the way the board should operate and cures some previous problems with the floating CPU/NB voltage and bouncing Core VID after extreme overclocking or a warm reset of the board after a failed overclock.
2. Bouncing voltages on Core 0 with LLC enabled and third party applications. We are still working on this one (offset mode while having LLC enabled will cause a slight/brief voltage swing). However, testing is being expanded tonight based on reported settings so far. I do want to say that using LLC and Offset together results in some weird behaivor patterns based on how each setting works (EE 101), to the point that removing offset is being considered or disabling LLC or Offset if both are enabled.
3. Higher than expected CPU VID or CPU/NB VID on auto settings when overclocking. Checking to see if we can adjust the ramp table based on HT Ref Clock numbers.

Thanks for the heads up on things Bingo...
As for Bullet point 3, the CPUVid (on auto) is probably about right for air cooling, although it does show a pretty heavy upward swing (even on PCProbe) right after booting.
Once the OS is fully loaded it settles down though.
The CPU-NBVid is more worrysome and goes way too high on auto IMHO, and doesn't settle down!
I haven't done alot of testing yet, but on the plus side it looks like it's clocking the HTRef better which really helps out on the 1055T...
I'll just use manual settings for now even though I lose CnQ and C1E.
I was really only testing "Auto"... In reality I'll probably never use it anyway...
I'll work with it more tonight, but first impressions tell me it's better than 0901 even with the quirks....
Thanks..... Dave

Is there any newer version of RAID Option ROM than 3.0.1540.59?
Sometimes hard drive detection takes a really long time, and rarely it says that my RAID-0 volume is offline.
IQ_NOT_LESS_OR_EQUAL
outdated hardware
Also noticed that the RAID detection is somewhat slower, also takes really long time after a warm reset (due to a failed overclock, bluescreen etc ).
Regarding auto CPU core - i find it convenient to run +4GHz and have CnQ ON to save some power (electricity) when running 24/7 high clock.
For 4.15 to 4.2GHz: 1.475 - 1.525v (CPU core with LLC on) seems to be right (atleast on my cpu) might need one bump higher for 4.2 ?
For 3GHZ NB F: 1.4125 - 1.4625v (CPU/NB with LLC on) seems to be right (again on my cpu atleast) also might need one bump higher ?
And also some way to unlock the 16.5 multiplier for ALL cores when turbo off for the 1055T would be great!

Hi!
I got a rather confusing problem, maybe someone can give me a hint or explain how the following is possible...
Got 2 sticks of gskill ripjaw ddr800-cl8 that flawlessly run timings of 8-8-8-24-1T @ 1666mhz (ref. clock 250, x6 1055 @ 3.5, turbo off).
ddr760@ ht ref. clock ~ 280-299 and Command rate 1T is causing errors in memtest86 within seconds - even with the slowest possible ram timings. only changing 1t to 2t results in no errors again.
(cpu @ default, ht link and nb around 2000mhz).
well, so far you might say that my memory and/or cpu/mobo aren't capable of running 1t @ that ref. clock but now imagine the following:
ht ref. clock @ 300 and higher ram, cpu and northbridge/ht link speeds and memtest can run with CR 1T for hours without errors.
anybody got any idea how that's possible?
In intel 965p times one might answer it's got to do with nb strap changing but that obviously shouldn't be the case here as the NB ratio can be controlled.
Thanx for reading the above story, I'm thankful for any answer or even question if further details maybe needed.
Best regards,
Albertini

Ok, let me be the first to report the 2MHz ht ref clock fluction is a goner with bios 0905! I haven't tested under Windows XP but with Win 7 64 bit the problem seems to be solved. Good job Asus!

There are no strings on me
Saw the thread; thanks for the support! Couple questions; I just got an M3N-HT so I can finally use this 1090T but half the BIOS options arent working it would appear:
Multipliers = No
Voltage = No
Dividers on certian mhz = Fail
CNQ Continues to function with or without it on
Turbo not functioning
If you have any info Id really appreciate it :P

Thanks Bingo13 for this initiative!!
By flashing 1602 I suddenly had 965 C3 running on 800 Mhz...
Instead of going back to older bios wich I read is not very simple, I tried this 1702.
I didnt test everything yet, but all seems OK, and multiplier problem is solved,
and my 4G OCZ black edition runs smoothly on 1600...
Thanx again and Greetz!
Is there any reason why the M4A79 Deluxe doesn't have something like LLC?
Or is there any other solution for the vdroop issue this board has?
I've asked ASUS support more then once about it, but they just ignore my question
After flashing 905 on the Crosshair IV. Most of my random reboots (caused by VGA failing) and failed starts have disappeared. I've had one failed boot-up since and one crashing of my graphics drivers. I'm still completely unable to overclock, even though on my previous Crosshair IV (I sent back due to faulty mem slot) I was able to receive massive overclocks with the same components and no instability. One change I've made is to include an extra two memory sticks, if removing these doesn't help, I'm concerned that the firmware is only covering up poor/out of tolerance hardware on some motherboards, which I've read was the issue for other Asus motherboards on other forums with similar issues that got repaired.
