**Unified** DFI LanParty UT 790FX-M2R-M2RS / Phenom /Data Base Thread**

Hmm but you have also tried high voltages and frequencies on the nb before you tried the lower settings if i remeber correct.

Not on the 2nd 9600BE
Undervolted first to find max stable & max bench with stock voltages.

Also you already had the freezing issues before. Can you remeber a phenom whom had the freezing issues right from the beginning without having applied +1.4V to the nb?

Last 9600BE and this 9850BE. I've not given this one more than stock NB volts yet, its always 1.3VID which gives 1.288-80v under load.

That's why I never pushed the NB on this one, left NB at maximum 2400MHz and mostly 2000MHz because for me, both are easily load stable at stock volts.

However, I'm not sure what is stable with NB anymore.. XP, Vista and Linux are showing different levels of stability for each setting

Crazy, good that i asked. I had the impression you are somewhat addicted to high NB clocks but have missed that you did not need that much voltage for em. My 9600BE however never ran above ~2.1GHz. Don't get me wrong, i', not a fan of an extreme undervolted nb. I try to find a limit where it starts to get unstable and normaly use 0.05V-0.1V above that for 24/7 use.
The chip stoppen working with 2GHZ nb at 1.3V however.

I contacted the lm-sensors developers and they might blacklist the board for smbus scanning. Meanwhile i'll try to read the sensors-detect code.

i'm sorry if this question is inappropriate in this thread. i got my dfi 790fx dk m2rs board a few days ago. i finally got a chance to fire it up. i'm in the process of testing stability. i can't help, but notice this high pitch sound coming from the pc. anyone have this problem with this board? is there a fix? the sound is deafening and i'm thinking of an rma to newegg. please help.

[Rammsteiner]

AFAIk there's no fix. I think you can RMA it though, but there's a chance your new board has the same issue though.

[dng]

i see, . dare i say it, i'm going to rma for refund and get a different 790fx board. what's the alternative to the dfi? msi? gigabyte? please advise.

There is NO Alternative to DFI! jk,lol. I've seen some DFI users witch to Asus but haven't any results yet. Gigabyte or MSI should be ok.

[dng]

does the M2R have the high pitch sound? i wonder if i can even find the M2R anymore.

The squeal happens sometimes just bad luck of the draw is all and all of them do not do it thats utter rubbish You can get the D.F.I LanParty UT 790FX-M2R Here.......http://www.ncix.com/products/index.php?sku=27484&vpn=LanPart%20UT%20790FX-M2R&manufacture=DFI

thank you all for your help, but i might go with the msi. still have 14 days to decide if i want to do the rma. do you know why the high pitch sound? i really the dfi board. i had dfi lan party boards in the past withing the nf4. i switched to foxconn for the 590 and now i'm going back to dfi for the 790fx. if not for the annoying sound, this board is pretty sweet.

As said before I posted my dead cpu issue in the lm-sensors mailing list. Seems there is an similar issue already existing with the DFI Lanparty NF4 SLI Expert.

I mounted an X2 5000BE in the mobo and tried sensors-detect again. This time the system froze but booted without problems afterwards.

With help of jean from the mailinglist we tracked the problem down to an unknown SMBus device at 0x2e. This device seems to exist at the same address in the DFI Lanparty NF4. Probing that device causes the system to freeze here and to reboot on the NF4.

How bad is the sound anyway? Is it nticeable over loud fans? I'm starting to hear things I may not like, but then again it's most likely nothing.

[dng]

it's loud even with loud fans and an open case. i wonder if a bios update will help. i'd much rather find a fix then do the rma. listening to this sound for a long period of time, can give me a headache or permanently damage my ears. i have another question, i migrated my 5000+BE and 4 sticks of crucial ballistix pc6400 from my foxconn 590 sli board to this dfi board. with the foxconn, i can oc to 236x14 with memory speed at 944 and 1:1. i can run the timings at 4-4-4-12 on the foxconn, but on this dfi 790fx board, i can't at all even with high vdimm. of course everything is left at default on both boards. the only thing i changed on the foxconn is the 4-4-4-12 timings. i have to run at default dram config on the dfi at 236x14. sorry, it's my first time using this chipset and the dfi bios is pretty intimidating.
