2920 is the highest I have reached on NB speed so far with this BIOS, but 2800 has been rock stable. I finally got up to 1180 on memory with a 4GB kit also, overall this BIOS is better, but still needs work.Quote:

HW monitor in bios and measured with multi meter.... windows software is wrong.Quote:

i tried the 1002 BIOS for 48 HRS but ended up going back to the 801 version. With 801 I could get the NB slightly above 2800MHz pretty easy, but with the 1002 I couldn't get it stable past 2600MHz. I also wasn't able to get my chip stable at 4GHz whereas I could on the 801. I'm going to wait for the next release and hope it will let me run my high NB speeds like the 801 does.
Prime stable 3 hour at 3800+ with 2800+ NB and bios settings it takes
Added max NB clocking with high ram and some PI to show efficiency also.

Bugs 1102
Cpu-z reports voltage incorrectly after 1.45v
K10 stat Pstate tab is not usable, even setting it to defaults = BSOD, believe this could be due to improper voltage reporting (AOD 2.14 works and current tab in K10 stat works)
vcore voltage is way off, off by 2 full steps, 1.6125 = 1.5875
Not really a bug but its somewhat of a struggle to get stable speeds that were known good on another board with same chip.

Just thought I would note something, I'm finding this board very inconsistent.
I am for now going to attribute it to bios but in the back of my mind i'm thinking dirty power is the culprit.
Chew:
What makes you think this board is inconsistent? Do you mean you are stable at certain times and not at others without touching the settings?
I've found this board to be quite quirky with vcore and I'm never really sure how much I'm getting once in Windows because I can't find an accurate piece of software. My clocks seem to be quite consistent, although they vary from BIOS to BIOS. I'm hoping a later BIOS release will help with the vcore issues. but otherwise I'm quite pleased with this board.
I've been saving profiles. Sometimes it passes prime somtimes it doesn't this is usually attributed to ripple = dirty power source. I double checked to see if somehow the profiles were'nt being applied properly and mnauallly set all settings from a new flash, same results.....Quote:

Heat is thine enemy! A cool day breaks 3.5g's : This board just wants more xtreme cooling!

Seeing the same here. Tested with two 940's now and getting strange behavior on both. Very similar too my old K9A2 plat v2 in that matter, dodgy when you push it :/Quote:

Bingo, 1102 bios was much better than another bios i was using (mod bios ).
Still a little inconsistent, most notable bug was at 1.63v measures 1.7vcore with voltmeter and in bios hardware monitor.....
I explored further and it seems everything after 1.6125 overvolts a rather large amount. .050 or greater.
Where is the vcore read point chew? I'd like to check the voltage out on my setup.Quote:

ASUS is working on it, we had the same problem under LN2 this weekend, voltages just flat ran away on us. Also, figured out the low NB clocking compared to 0801, should get that fixed also. MSI just got me a BIOS that looks like it might work this time. ;)Quote:

Sounds good looking forward to the MSI.
Matt as per your request.........I'm working out a vmod as we speak but bear with me i'm amatuer at best with this stuff.....I will likely get a second hand opinion as I hate giving misinformation.Quote:

I only have a 9700LED for now but plan on Swiftech H20-220 APEX Extreme kit for cooling. Stuff it all in my Antec 1200 with Antec TP 1KW psu. Any pointers would be greatly appreciated. Aloha.

4 mosfets at the bottom of the ram slots get a tad hot, will have to be low profile heatsink....vidcard willl interfere....Quote:

Trying to get my new 2x1GB OCZ Platinums stable i had to set Vdimm manually to 2.1V and Trfc to 195ns for both. I got a few errors in the black slots but none in the yellow ones. :)
Yesterday i was able to boot at 19,5x200 and run 3d mark06 at just 1.51Vcore, after that it isn't even stable in windows any more at the same settings and still ain't.
I'm still pretty much puzzled by this sytem. :shrug:
Zeus set your clock skew DPS to normal for the OCZ's with 1102 I'm using 2.24v for 1200 ram ;) you want a shot of my timings? I might be able to be persuaded to whip out my platinums, Preety sure i can crack 1200 with them.......just don't need that much power atm....Quote:

Leave drivestrengths on auto for now, I haven't fine tuned them for max performance yet, as I've been busy and its time consuming to get it right. Looks like I forgot to set DCT mode, Run it unganged......
I'm running in the black slots. 2 x2g OCZ golds, might give my 2x2g OCZ plats a spin tommorow......

Does anyone know why my board is having problems reporting the FSB correctly? Like I will have it set to 200 in the bios, but cpuz reports it as 200.7, or even sometimes it went down to 193MHz when set to 200, with a 16.5 cpu multi, NB of 2400, and HT link of 2.0. And if move the FSB up to even 201 it still reports as 201.7 I'm running vista x64 also if that matters.
