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

[Brother Esau]

i have a "X files" here....

Whit Vista 32b i can OC up to 2.7 ( tested whit 2 hours of Prime and Ortos)
but whit Vista X64 i can`t go over 2.5 ...
There are any trouble with X64 and OC in this DFI board ??

Thanks for you replies..

There are many documented cases on this forum with Phenom not O.C well on both 64 Bit XP & Vista its not isolated to the D.F.I 790FX

I've shimmied up the wrong tree.

^ No there aren't, Campbell is telling tales now guys, beware.. it's just DFI, only DFI

Only kidding, Camps right

Very sad this information,i have 8g of ram and i need x64 to work.
i will try whit Ubuntux64.

[KTE]

^ Ubuntu X64 is even harder than Vista X64 to oc, trust me

[sea_man]

.... bad news for me...
but i don`t understand what kind of problem have the phenom OCed whit X64 OS ?
i`m a little disapointed of this
whit my last config ( ix38 quad gt and e6750 OC to 3.8 all was going well, Vista X64 , Ubuntu X64.... also OSX86)

That's old and wrong. Search around, its been dealt with here before. It was BIOS problems on AM2 boards which were mostly unsupported, have a read of the complete thread

No such thing around, try for whatever is max stable on your CPU in 32b 2GB/4GB and then move on to 64b, like many are doing.

Thank you for the explanation.
today i install XP 32b, and i can go to 2.75 stable....

i will trie later install Vista x64 to test...

[railmeat]

can certain Phenom models get 3ghz on good water easily or no?

[unkn0wnhacka]

my cpu can get 3.0 with no voltage tweaks at all... just boom!! 15x multi stable

[KTE]

Very good result for 9550 there sea_man
Exact same parameters including voltage are my past favorite setting too with 9500.

railmeat: yes, and above.

sorry for off topic slightly with my answerd question on the phenom.wow unkownhacka at your good 9850 clocks there man and NO VOLTAGE tweaks,wow

Except HT/NB multis @ 9.

My RMAed 9850BE arrives tomorow, meanwhile...

[KTE]

That same old clock-loving 9500?
Is that a new result or an old setting you've been running?

Yeah I liked the 250 HT setting for a few reasons;

2750 CPU
2000/2000 HT/NB without voltage change
1000 4-4-4-4 2T RAM without voltage change
All a good balance and tweaked

Today's result, and new setting after returned to 307 bios, so todays setting too, benched 3d06/3d05/3d03, had worst results on the first ones compared with HTT=255 NB/HT=x9.

Yeah I liked the 250 HT setting for a few reasons;

As been my "default" setting on this 9500 since the MSI board, except for NB/HT.

I will order in the next week an Crosshair II, and keep this DFI/9500 combo, for my collection

Time to an AMD engineer and get them to fix it.

Amen my friend.

[Brother Esau]

Quite dissapointing native 64bit processor does not work well with 64bit OS

[KTE]

Maybe people are forcing their Phenoms and pushing higher just in the hope that they'll clock stable higher than they really will?
I mean if you run 2.8G, test it, while that's actually unstable for the CPU, then no matter what you try, it will be unstable, even though your overclocked heart can't accept to lower it anymore. Just because you benched it doesn't mean it's stable or doable MHz

Yeah... like I said earlier, you're too rich for me

BTW, I have 2.8G stable in 32b and 64b, not tried more yet.

[Final8ty]

aGeoM given up on the 6400BE ?

[Rammsteiner]

Oooh, as in 100% stable? What settings regarding Voltages, HTT, multi's etc?

[AlabamaCajun]

I see a lot of posts by KTE regarding what people should do but I see no reference to what used or succeeded with nor does he have a sig. I browsed browsed back a month or so and no posted results, may need to go back further.

We appreciate the responsed to our questions but when we are trying new hardware we need to know what you are doing. Moral support just makes us feel good but does nothing to get the piece of hardware to run as advertised. I'm going to shoot for what I bought this for 2.8G but will settle for in the 2.7G range sable. Not all of us are hotrodders but when hardware can't even run at stock or 100M over then something is wrong.

[Brother Esau]

Oh jeez I see how this is gonna end up already @ALABAMACAJUN......KTE is on allot of hardware and bounces back and forth frequently Gigabyte , MSI 780G 790FX also others and even DFI as of late but that equated in no go (Board bad) now he has done this from the beginning and has been one of the main debuggers with Phenom since launch date so much so that I recommended he be made X.I.P which I might add he turned down because he wishes to remain the same as everyone else which is just a common guy working in the trenches along side everyone else Please don't bust his balls he knows what he is talking about and has contributed probably the most towards the cause. You know as well as I do that there is not stead fast applied rule to this game and what works for me "may" work for you and also maybe not too. Thats just the nature of the Beast

[KTE]

Oooh, as in 100% stable? What settings regarding Voltages, HTT, multi's etc?

Yea. I posted it about a month back, Ubuntu 64b is 100% stable for me for a while now. Infact I'm reinstalling it at those settings.

Problem is it needs high voltage, 1.480v for 2800MHz to be stable. Doesn't give me any error at that and at 2700MHz 1.352v. Haven't tried anything else nor did I change any other parameter from stock.

I see a lot of posts by KTE regarding what people should do but I see no reference to what used or succeeded with nor does he have a sig. I browsed browsed back a month or so and no posted results, may need to go back further.

Nearly all settings of mine used and what not have been disclosed across the AMD section of this forum but I haven't replied to a concern of yours that I can remember you asking or wanting to clarify. In case you haven't read before a month, my 9850 has had no boot since about a month on all boards I had - until now. What is it you want to know exactly?

Thanks Bro but you know you don't have to
