I update bios in anticipation of the 940 from 2101 to 2205? The newest one and installed the 940 and cleared CMOS. Upon reboot it wouldn't let me save my settings in the bios when I enabled the raid controller. After I saved all my settings in the bios and rebooted it would just show a black sceen no beeps no error messages. I finally got to load the older bios 2001 and got the machine running. And instead of clearing the CMOS just updated back to the newest bios. But asus never replied to my emails. I thought I may have fried the board. Thankfully I didn't.

Hi! I had called ASUS on this very thing......They told me the 940 may not even "POST" and may have other problems with the M2N32 SLI Deluxe.... I've ordered the M4N78 Pro....I'm a flight Sim guy,so 1 PCI Express slot is ok with me.....I also wanted the DDR2-1066 Mem option......Good Luck

Guys the new bios 2205 will use the ddr1066 just fine with the x4 940 BE. The mobo should use the cpu just fine as well providing you don't try to push an overclock to much. The cpu is a 125w cpu and the mobo is designed up to a 125w cpu so if you overclock the cpu too much you end up stressing the onboard componants too much and frying the board. It will run the 940 at stock settings all day long no problem w/the updated bios. You will need to use a older cpu to update the bios before dropping the cpu in if you are running one of the other outdated bios's. The best way to flash the bios is w/a cpu that the bios is detecting properly to begin with and set the bios to optimum settings or reset the bios and clear any of your bios banks if you saved any of those so that they will not interfeare with the flash and then when you put the new cpu x4 940 in get into the bios right away. If you mobo does not boot to a post screen then try to push the reset button. Next after you pc resets push and hold the F1 or F2 key before your pc post's and hold it untill your pc post's then press Del and get right into bios and set your cpu voltage. F10 save and reboot. After this if it does not post hit reset it should post then go back into your bios and make all your settings static not auto. you should be good to go.

Let me know if you don't understand any of this or you have further questins.

i got waorking for almost 2 weeks already, but just posted that cause think3r asked..
i updated the bios with my 5000+be and for some reason when the 940 was in it wouldnt let me save any settings in the bios. after saving settings and reboot it would black screen. so i loaded 2001? and then put the 940 in and did the settings in bios and updated the bios to 2205 and for some reason that worked...
and yeah i cannot really push this cpu too far before i get bsod. i got it to 3.4 but thats pretty much the farthest it would go, didnt want to stress it to much. i run it at stock speeds and thats fast enough for now till i uprade boards later.

robit try doing what i did.

nalo b, how did your lap job go,did it help your cpu temps any.

N2Gaming, I'm sure the TDP goes up when the PhII 940 is overclocked but I don't know about the onboard components "frying" themselves. If the board supports 125w processors then I hardly see a problem with that. Remember also that the 940 isn't "officially" supported under the M2N so there may be a reason why a component or two may fail.

Good luck

i think it helped... this is the first time i lapped a heatsink, but i didnt use 1000 or 2000 grit sandpaper. it still idles about the same as before i did it. around 40-44c but it doesnt hit 60c though. i tried running 4 different instances of orthos and it goes to 58-59c but thats the highest. im sure i didnt do a good job at lapping it though. did research after the fact that i already lapped it i wasnt suppossed to put force on the heatsink when sanding it and supposed to use atleast 1000 grit, i only used 400.
but i did it just to hold off for a little while before i upgrade heatsinks. and so far the xigmatek looks promising! is there a difference with all the different variations of that heatsink? seen maybe 3 or 4 different models of that one that you posted.
all in all i have to say since you told me to turn off that seting in the bios my temps went down atleast 10c. i think i was idleing at 50-55c...
thanks again Gyro!!!

Ok I've just spent the last 2 hours getting my new Phenom II 720 BE to work on my M2N32 SLI Deluxe, here's my findings.

BIOS 2205 does NOT work.

I managed to post my PC under 2205 (after hard reset the CMOS data with jumper), in fact, 2205 recognized the new 720 BE CPU, however after I setup all the settings, saved it and reboot, my PC just doesn't POST.

I've to reset the CMOS again to make my PC to post again, but everytime I reboot it won't post until I reset CMOS memory.

So after 10 tries, I've rolled back to BIOS 2101 and while the cpu is not recognized, it worked. I can save my data and reboot properly.

The default vCore voltage is set to 1.36v if you use the "Auto" setting, and the CPU runs really hot (55-60C) I've to manually set the vCore down to 1.30v to run it slightly cooler.

I've managed to run it @ 3200 Mhz (200 with 16x multiplier) @ 1.30v.

I hope this info helps whoever want to run a Phenom II x3 720 BE on a M2N32 SLI Deluxe.

p.s. since BIOS 2205 recognized the 720 CPU, I strongly believe the next BIOS release will properly support the new AM2+/AM3 Phenom CPUs.

Solos2, welcome to OCN

Thank you for reporting your findings for us in regards to the 720BE and the M2N32-SLI Deluxe. Kind of strange that the 2205 recognized the processor but didn't want to POST after changes were made. If you were to just go with the "factory defaults" in the bios does it still not POST?

Good luck

solos2,
thats exactly what was happening to me with the 940be. after going back to bios2001 make all your changes in bios then reboot and install 2205 it should work. but after a bad overclock had to it all over again cause 2205 will not let you change certain things in bios. it will freeze up after reboot. it happens with me when i enable raid in the bios.
hope that helps.
