**Official DFI LanParty UT 790FX-M2R Review/Overclock/Guide Thread**

[Oese]

you have 8gb of ram running??

OK. Here's the results of playing with this whole setup most of the day, aside from a flare up of reboot fatigue syndrome

The 9850BE seems to have no trouble running at 3Ghz all day. Its the DFI 790FX-M2R that seems to be having a schizophrenic time handling the 9850.

1. The system will consistently RUN at 3Ghz.
2. As Nico pointed out in his TTR post, it does NOT always like to BOOT to 3Ghz
3. I can get it to boot to 3Ghz by having CPU voltage set to 112.82%, yielding 1.45V, which is somewhat high, but not ridiculous (I'm on water, although I'd be dubious about doing this on air)
4. There is definite MISMATCH between AOD, Smart Guardian and Everest on many IMPORTANT readings to tweakers and modders. A variety of voltages are simply inconsistent
5. One PECULIAR item of note, is that I boot using the BIOS voltage setting of 112.82%, which yields 1.45-1.47 volts in SG and Everest. the MINUTE I start up AOD, the voltage DROPS to 1.38-1.39 in SG and Everest.
6. AOD definitely has value now with Phenom, but the BIOS and AOD do not agree. Voltages are clearly not the same in both.

All in all, my confidence with the Phenom is starting to grow. Its pretty obvious that more experience and testing is needed to further the development of Firmware for these motherboards, and to tighten up integration between AOD and BIOS.

Its clear to me that there is something that happens at boot time, that is different than run time as it relates to CPU state. My simple mind might drift towards there being some kind of voltage drop during boot up that causes the CPU to not be able to tolerate 3Ghz at bootstrap, causing BSODs. But after about a minute of steady state, the system runs just great and will Prime all night.

Yup...they have to warm up, i found the same

There is new bios on the way from DFI I hear, we just need to wait and see what they managed to fix

@nanohead: I had problems running at x15 multi too in order to get it to boot stable I needed almost .5v more for a total of 1.44v (still testing ~19h running BOINC) when at x14.5 multi I only needed 1.39 for it to be stable (~28h running BOINC).

Anything higher than x15 multi is a no go though tested until 1.525v in BIOS and it would boot until the windows orb and then BSOD.

I think that i'll try some HTT overclocking a little later just want to "break-in" my phenom right now.

Thanks Jaivan....

Yep, exactly the same thing I'm seeing. It'll run at 2.8Ghz (14x200) all day long at stock voltage. 14.5 needs around 1.37-1.39, and 15 won't boot consistently at any voltage. Funny thing is, that I can use AOD to turn up the multi to 15, and then Prime on all 4 cores forever. I'd be curious if you experienced the same thing. Booting is one thing, but running is another.

I also tried lots of different combinations of lowering HTT, and raising HT with a lower multi, etc. But the bottom line is an overall CPU clock limitation. No matter what recipe I used to get to 3ghz, the system was unstable and inconsistent. I read Tony's article, and tried lots of those tricks, but no matter what I did, higher clocks were unstable for day to day use on a gaming rig (after a while, I do get sick of playing with my system, and just want to play some games )

There's much more speed here with this 9850 for sure. Just gotta get past the booting issues and initial stability. Because it'll run so fast, I'm willing to bet that there is something that can be done in BIOS to make it more consistent

Yeah, its amusing actually. Never met a solid state device that needed to get cozy first before reporting to work

Hey guys.....

Got all set up last night, I got the DFI 790fx-m2r with the 9850, and I got 2x2gb Mushkin Redlines DDR2-1000. Havent really messed much with it, but, I tried to slow the ram to 800, and when I do it wont get past the Verifying DMI Data Pool.
When I get home tonight I am gonna flash to the bios Brother Esaurecommends, I think the 1/30/08, not 100% sure right off.

But any ideas why this is happening?????

Yep 1:1

Please tell me if that 2x2gb Redline PC2-8000 will boot at the 1066 divider please leave at all defaults and go into Dram Config Page and just change the Auto to Manual on the top of the page leave everything else as is at Auto!

Main Genie Bios Page Change Ram Frequency to Manual and set 1066 divider Save/Exit

Update:.... After Reinstalling Windows Vista 32 Bit without any Issues with it installing with 2x2gb OCZ Reaper HPC (PC2-8500) what so ever I got all of my Updates and SP1 Installed it appears that the TLB Patch associated with Vista SPI update is not applicable in any fashion nor is it applied with the Phenom B3 rev in place

@ Brother

Linky is bad.

How are you guys getting these bios and are there beta available for the

M2RS?

[justapost]

@ Brother

Go to DFI's bios page and change the STATUS_FLAG=A attribute in the URL into STATUS_FLAG=B.
I tried it for the M2RS and there where no beta bioses. Site went down a minute later.

[Slagathor]

Yes, I am runing 1066 on the ram, everything else on auto.
this stuff http://www.newegg.com/Product/Produc...82E16820146755


I think I got to reseat my TRUE, running the stability test in AOD and it's reporting 50c per core

DFI site keep getting a java sql error, was gonna go bios hunting.....

Green button = Bad?

They always have issues with their server when Beta's are posted up on it and it takes a couple of hours or whatever for it to regulate why I do not know

I have not installed it as of yet have allot to do today and don't have time to get involved in all of that right at this moment By all means please some one install this Beta and give us some feed back on it

No M2RS Bios M8 sorry, I checked though for you guys.

[Slagathor]

Green button = Bad?

So, how do I go about making the button red????? heh

If you already grabbed the bios host it up m8 as it looks like the whole of DFI LP site is offline

[Tony]

put the mouse over the button and left click

[justapost]

There is also a new version for the sapphire clone available.

Sorry Tony did not download it figured I better wait because I would be to tempted to get involved with the Lunacy

BTW...have you suggested to Oskar that he get some better support for AMD Over Drive rolling with these Bios Releases that will be up and coming?

[MKroenke]

http://us.dfi.com.tw/Upload/BIOS/R7LD415.exe

This link should work. Has anyone flashed yet?

[Brother Esau]

Not as of yet and if I may make a suggestion to all of us with this board that wishes to load this 4/15/08 Beta and test? I would say wait until the FTP Site is regulated and functioning normally so there is less chance of the actual file being corrupted from the download process

[Undersea]

I second that. Its nothing new though because lots of MB didn't run ntune right either in that era.

Oh I got this

Could you reprogram a M2RS?

[Brother Esau]

[QUOTE=Undersea;2921201]Could you reprogram a M2RS?[/QUOTE]


Yes I can thats a non issue!

[Slagathor]

Another quick question about Motherboard temps.
I do believe I am running 12/11/07 bios, but, when running stress test
Everest reports motherboard at 75 and climbing, I installed the transpiper outside the case, and the heatpipe is very much warm.

How hot is to hot for the mobo????


Here is just 3 minutes of AOD stabilitytest:
