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

[Ben_Brown]

I will chime in about the MSI board not being stable at "every day use Idle" Prime95 runs fine, Idle with nothing open causes no problems, but if I open up for instance outlook and leave it open, BOOM crash within 30 minutes.

Specs are as follows:

http://valid.x86-secret.com/show_oc.php?id=346252
With vcore @ 1.336 and NB @ 1.225

[Rammsteiner]

Ok, that clears things up then.

Is there a way to compensate by clocking the IMC lower and CPU higher for example?

[Rammsteiner]

K, nevermind, that doesnt work.

Just finished 2.8Ghz Prime 6h+ stable, like 1 minute messing around after I stopped it and BSOD.

Now Priming 14.5x200. 15x200 froze at start up, but 14.5 doesnt. Priming not anymore for the 8h+, just a little while so I know that part is stable(ish).

Ill dig in the MSI+Phenom thread KTE, where you had some results noted (think it was you lol).

[KTE]

I'm trying to find a stability testing method which does work for Phenom since this problem can crop up on all MFG boards so far. Have not found anything yet apart from general usage first and foremost but I'm going to give PassMark Burn-In Test a try as it loads all the area's I need to check for stability running them against pre-determined calculation values. So, far easier to catch minor instability.



Simply, I'll run it on a setting I know passes P95 but fails general stability and see if it can find error as well as running it at a setting completely in error for both P95/WISE and lastly for a setting that is known fully stable. WIll post results when I have 'em.

What of CoreTemp is that accurate?

[Brother Esau]

I have some qs for you DFI users with Phenoms;

- Does speedfan still kill/crash your board? Stay Away from Speed Fan!

- Do you still have voltage problems with only special add option giving you increase Vcore? ~ NO there are no issues that I am aware of on 4 different Bios /phenom!

- Whats max vCore added through BIOS special add option without changing VID? ~ Don't Know Tye will look into it

- Does AOD now work with your boards without crashing, at all? ~ So Far its a worthless Pile of Doo - Doo and has never functioned Properly

- Can you change VID in BIOS and still set low CnQ VID/Volts? Don't know would be interested in finding that out myself

- How much difference in options is there in the BIOS for M2R vs M2RS? ~ No Difference in Bios Options just Bios Code is Different do to 4 Phase PWM on M2RS

- Do you still have whacko temp feedbacks compared to all other 700 series boards? [most likely ]~ Some Bios are off but for the Most part not by much and they are pretty accurate!

- What's the best Phenom BIOS you have?~ Cant answer that accurately but so Far 1/30/08 works well & 4/15/2008 Beta seems to be a winner and I like it

- Have you worked out what these options are or what they affect yet? Don't have a clue in Hell what they are for

Bout the Best I ca do for you Tye ATM but will submit more Date and bring you up to speed. So.....Stand By To Stand By

[Oese]

newest speedfan beta works here, but i had luck non beta version did not shoot my board only shutdown and no reboot without cmos clear..

don't use it at the moment, cpu-fans are regulated by pwm-temperature here

max vcore by special vid is 1,5v (=125%) at least (with 1,2v VID at default)..

[Undersea]

You don't get out much do you? I wanted more than anything to get Vista 64 Bit but many , many , many people on this forum have documented that there is Indeed a Issue with Phenom and Windows XP 64 Bit & Vista 64 Bit thats why I am running Vista 32 Bit

Also if there is anything that you should have learned by my constant Psycho Babble and carrying ons with 4 Part Harmony and full orchestration is that AMD Processors DO NOT respond well to High Voltage!

Right now I am Priming @ 2800mhz Vcore @1.24375 which equals Less then 1.23Vcore (Real)- Vdimm @ 1.80v - NBvoltage @ 1.200 - PCI-E NBv @ 1.200 - NB-HTvoltage @ 1.230

X14 200HT ~ NB @2GHZ HT-Linkwidth 2ghz 16 Bit address extension 1066 Divider set Ram @ 5-5-5-18 trc 23 195ns

I'll have mine up tonight with Vista 64.

SPEED FAN is a Killer and best to avoid it and its not neccessary to begin with! Use Smart Guardian and Core Temp thats all you need

Will this run in Vista 64?

I really like HWmonitor also.

I have some qs for you DFI users with Phenoms;

- Does speedfan still kill/crash your board?

Keithlm had a corrupted bios after running sandra.

- Do you still have voltage problems with only special add option giving you increase Vcore?

Both work, even in conjunction.

- Whats max vCore added through BIOS special add option without changing VID?

think it was 133%, not sure.

- Does AOD now work with your boards without crashing, at all?

On startup AOD applies an 1.25V vcore and 1.3V CPU and NB VID. Also 1.8V is applied to the ram. Seems it can not read the real values. I guess if you use AOD only it will work with modest bios settings working at startup applied voltages.

- Can you change VID in BIOS and still set low CnQ VID/Volts?

Don't remeber I reported about thos issues round page #24 here a while ago.

- What's the best Phenom BIOS you have?

Had best results ref HT wise with 3-07, the latest beta seems to be good but i have not yet tried it.

- Have you worked out what these options are or what they affect yet?

Sapphire has a bios manual which describes those settings, have not yet played with em.

BTW: I'm really happy with the xigmatec here, thank's for the recommendation. Getting ~8°C lower temps than with the BigTyphoon under load. In idle the temps are equal.

[illogical]

OK so my nice new 9850BE has been running at stock doing AVI to MPEG2 conversions for most of the day, fast rock solid stable, RAM at 1066MHZ.
So I decide to try upping the multiplier to 14, as you can see in the BIOS screen.

Yet CPUZ still say I'm at stock.
Using the latest Beta BIOS 415, obviously I'm missing something but I don't have a clue what.
Any help greatly appreciated.

Try it with Cool and Quiet disabled please.

[Brother Esau]

Set 1.2500 Vcore as you do not need stock voltage defaults on these Phenom and also turn off TLB Cache Fix too

[illogical]

Thanks guys, now running at 2.8Ghz idle temp is 32, just love the Zalman 9700.
Next thing is to get my memory timings a bit tighter.
I'll just let it work away over the weekend, sort of a burn in period, then see how far it will go next week.

I agree with that assumption as well Achim

[Oese]

flashed new beta...

now cpu-temp idle is much too low...

8°C lol

besides that i'm priming

Did you Flash the way I recommended one page back Oli?

[Oese]

aye

How do you get regular numbers in your bios????
I got Hex....






Is it the beta bios??? I got to guess......heh

I am going to flash tonight though, hopefully theres a store here with Floppys...heh




EDIT:
Brother Esau, you got a link for the 4/15/2008????


Never mind, found it.....

[Brother Esau]

One thing I notice thats a definite with these Bios Release is that what will excel at Dual Core will yield different opinion and view on Phenom and vise versa I would Imagine I guess its a very fine line and Juggling match balancing the Bios work for K8 - K10

[Oese]

yeah think so either, but besides temps, i don't think these biosses must decrease in x2 performance naturally if being optimised for phenom..

i think theres profiles for phenom and x2 cpu and they both mature in parallel?

but perhaps some global chipset settings will be on the phenom or x2 side...

[hive]

hey Brother Esau is it possible to get the OCZ DDR2 PC2-9200 FlexXLC to work at 1066mhz without that spd modification.

WIth the newest bios of course with the microcode update ?

[Slagathor]

Tried to flash again, and again a part number mismatch......


Words cant describe how ticked I am right now.....


I wrote down the number on the bottom of the post screen.
12/11/2007-RD790-SB600-6A66AD4ZC


I know it's an M2R, I am totallt lost as to why it wont flash.....
