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

[=[PULSAR]=]

okay well just updated bios and it booted into windows for like 3 mins and then crashed and having the same problem as last night. I think I may just RMA this board.

[Brother Esau]

Listen man ....don't you find it odd that this happened right after you Installed new drivers without uninstalling the old ones first?

Not to be offending in anyway but I have to be honest with you I think that this is a user created situation and has nothing to do with the board! You should not be updating Bios unless the system is stable and has been tested to prove such and more than likely with the way you were spiking that CPU with Vcore no doubt you did not take the time to read the first page where its plain as day to see that you can pretty much get 3500mhz 800HT X10 Multi with stock board voltage. I would be willing to bet that you jacked the voltage up on all settings in Bios instead of first understanding what you had first and foremost!

ITS A DRIVER ISSUE!!!! GO INTO SAFE MODE AND UNINSTALL THE CATALYST DRIVERS AND USE DRIVER CLEANER CAB CLEANER THEN USE THE PROGRAM TO GET RID OF ALL ATI RELATED DRIVER REGISTRY ENTRIES!

OR REFORMAT WINDOWS IF NEED BE!


P.S......Out of Curiosity did you do as I recommended 3 posts above last night or was that too much to be bothered with?

[=[PULSAR]=]

I did all that and then went and uninstalled the ATI drivers and used driver cleaner and it still persists. If I wait a couple hours in between boots its fine but then after a simple restart it wont boot at all. It will just show DFI boot screen and then restart again and again. Also when I reset CMOS it will always hang on the raid controller so I have to disable it before hand.

[Brother Esau]

Was it doing that before you updated the Bios? And also just so you know 1/3/08 has a completely different ATI Raid ROM Bios from 11/22/07 so you are not going to get far because you have borked your raid array just read the notes attached to the bios page and it will tell you the same thing!

[=[PULSAR]=]

no, I think its a problem with one of the motherboard components burned out or is failing I'll try and take a youtube video tonight and posting it. Even if I'm having a bios issue I still have the problem of the computer not even turning on and it was doing this before I did the bios update.

[Brother Esau]

RMA time man! Perhaps you may find interest in reading my OC Postings with full Bios Template on the first page before throwing the board to the Electric chair with Voltage next go around I find that its best with any board to break into it gradually and take it slow as Instant gratification has never proved worth or merit with anything in my eyes!

[Nedjo]

I'm on a brink of ditching this mobo!

It's just… it has so much small, but nasty quirks… it pissing me of!

I've already wrote, how after switching off in situation when Phenom is slightly OC'ed, I get cold boot!

Then I need to do EZ clr. cmos, and do the settings once again… here comes even bigger anoyence!

If I don’t do it exactly right, I'll get code "75" and will need to do EZ all over again! Namely, when I want to OC CPU, first I need to Disable C'n'Q (also I disable Virtualization), do the "F10" go back in the BIOS, and do the multipliers, and voltages! If I want to do all settings in just one BIOS entering, I'll endUp with code "75".

BTW, I need to setup mem. timings twice! First time doesn't count. 'cos next time when I'm in the BIOS settings are within auto values, so I need to set them up again (of course no "15" for tRAS, 16 is the lowest value)

I'm a character with lots of patience, but this is just getting ridiculous!

[Brother Esau]

The Bios they have for this board right now SUCK!!@!

If D.F.I does not get the hooks out of their asses with this Bios situation like pronto there will be no one willing to buy this board for that reason!

Hell I am only on Dual Core and I have tested all of the Bios extensively because I have a Bios Programmer and have flashed /erased/ re-programmed/re-flashed about 20 times now and the Bios Suck....All of them!

[=[PULSAR]=]

I remember when DFI used to be the when socket 939 was out I guess alot has changed since then.

[Brother Esau]

I really don't know what to say about this , I really just don't! We certainly are not working with NF4 Bios thats for damn sure and whats been released beta or official are Horrid as far as Bios from DFI goes and I believe that my biggest fear with getting this motherboard was going to be that the Bios were going to be AMD release Dependant unfortunately seems to be true. As we all know AMD is in a boat load of trouble right now and focusing in on new releases and from what I read with the Phenom failure with their stance on this they are what appears to be abandoning whats going on currently and focusing their resources in on new products

You're wrong here my friend. BIOS is no way AMD dependent, it's just matter of resources one mobo maker is willing to put in it.

You've noticed bunch of LanParty models based on Intels' "series 3" chipset form DFI. And we all know that DFI isn't really big company. So they've focused all of their efforts towards Intel's product line, and that's way their first AM2+ offering suffers this much.

I do believe that things will get better in a matter of weeks (after all couple weeks after this UT mobo, they've announced DK part of this LanParty series…)

Only question is how much are customers like our self are prepared to wait?

Regarding the AMD, they're putting all of their effort behind Phenom. And Phenom is by no means failure. Who ever played with this processor more than short period of time that reviewers on the web do, will tell you how positive experience in terms of delivered performances. Inevitable part of that is the feeling that CPU really needs just something little more to unleash its full potential. IMHO that little more is MHz's.

Regardless of the feeling, fact remain that we've witnessed hard birth of the new architecture. But if you put aside TLB fiasco, delivery of K8 haven't been much different… it's just that competition at that time was much inferior, and AMD didn't had this burden of FUD stories around it's neck!

[Brother Esau]

Oskar and crew are in control of Bios programming that I know as fact but also too the source code is obviously lacking which has even been stated by Tony and unfortunately source code will be AMD /Award Dependant not DFI as they can only work with what they have such as reference design on mobo thats also not DFI, Gigabyte, Asus choice either and they must work within those constraints as well.

As for DFI spending more focus on Intel Bios programming over current not so popular AMD I agree whole heartedly on that but the fact still remains the same these Bios are shameful releases by DFI's part

[ZL1Killa]

I'm still watching this thread. Currently just playing with my 6400+BE campbell. I want to do a mobo upgrade as it will stabilize my Vcore on the cpu a LOT...cuz this one fiddles around too much. Only thing is with the bills i got right now it ain't happenin' anytime soon. I also like finding out all this stuff knowledge is power.

[serial099]

Hey BrotherE,

Don't have my Phenom BE rig totally up and running yet (waiting on a new hard drive from newegg to install windows on) but I do have it running up to bios. What setting exactly did you want me to check out in the bios. The m/b is still running 11/22/07 bios, btw due to inability to flash it as yet. And based on experience here as yet, I just may wait to flash it until something more stable comes.

Also, for the transpiper unit, where is the best place to put thermal paste? On the pipe itself or on the hold down plate or somewhere else? Reason why I ask is after like an hour of idling in bios my mosfet temps are 68c and my n/b is sitting at 62c while my cpu is at 24c. I have a 70mm fan I'm going to hook up to it on the way, but this is something I could try out while I'm waiting to see if it'll help any.

BTW, pic of this screen shot from bios in my worklog.

Hey, whats up? The Bios stay put on 11/22/07 and the transpiper deal just use this link and do as they illustrate and use ASC thatss what I use / Also those temps are really hot on PWM and NB I would recommend taking of the heatpipe assembly carefully and inspecting whats going on with the TIM application and re-apply the shinetsu that comes with it if need be and make sure when you re-install it to uniformly tighten the machine screwsbut don't crank it down excessively as you don't want to crush the PWM, SB , NB

[serial099]

I was afraid you were going to say something like that.....I think it would be pretty much an all day event for met to try and re-apply TIM to the heatsinks now. *sigh* I guess I'll work on that sometime this weekend. I use MX2 for paste. It seems to work pretty good overall.

[Brother Esau]

Negative! You need a thicker bodied paste for Transpiper , and also Digital PWM ,

[serial099]

Well, I have AS5 as you suggested and also some Thermalright. Never used the latter of those two, so I guess I'll probably stick with the as5 for this mess.

[Brother Esau]

Artic Silver Ceramique is what I suggest for the Transpiper and just use the ShinEtsu thermal Paste that came with the Motherboard for the PWM , NB, SB

[serial099]

Well, to save me another purchase, AS5 should work decent though, right?

Oh yeah, in that Transpiper setup link I realize that the copper piece might be optional, but where to get a piece of copper like that? Don't suppose they sell those possibly pre-cut online somewhere do they that you know of? I would just buy some stock and do it myself, but no machinery to do it with.

[Brother Esau]

I am sure but the ceramique is thicker and cheaper and I can speak of the results because thats what I have used for the Transpiper.

few things here... first, code 75 is the step the board is detecting ur harddrives

second, has anyone been able to find "F2-8500PHU2-2GBHZ" g.skill mem kit??? ... i want these real bad to replace my ballistix that died but i cant find it anywhere... if i do find them im afraid of the price they'll be

and finally, as of the 1/3/08 bios, this board is friendly overclocking with a phenom only when these conditions are met:
#1, nb/ht/pcie voltages are kept at STOCK... this board is PRIME95 stable 8+ hours at 8x247 (nb hex 04, ht "1.6ghz") without touching these voltages anyway
#2, 8x or 7x multi are the only 2 multipliers that seem to work currently for nb+ht when using 201+ ref, and really 3x has no purpose yet as 250+ ref is only good for a minute of benches anyway
#3, ~240 reference requires 3-4 in "reference clock adjust gap", ~245 requires 2 adjust gap, ~247+ is difficult to post if adjust gap is not at 1... i dont know why or what that setting is, that's just what i've discovered... if anyone has info on this one, plz share
#4, this one im not 100% sure about, but ddr2-800 setting is the only one that's really functioning, ddr2-667 posts once every 20 resets and is not stable ... this might be due to trfc timings but i havent had time to dive into it yet... my board does it with my current g.skill and ballistix that died

please look at my signature for my o/c setup... it is 100% stable without ANY "quirks" using 1/3/08 bios... i am noticing the latency problem playing online games however, and will try reverting back to an older bios if another beta isnt released soon

[Brother Esau]

Congratulations and great feed back Iketh You qualify for Free Re-Programming in the event anything goes wrong on you're end

Just like I said though originally the NIC Bandwidth and Ram latency was a complete bust on that 1/3/2008 Beta and there are still values wrong with Ram Table also and weak/Normal drive Function does not work properly since after 11/22/07 Official and still slight annoyances with USB issues as well and also Randon C1 Error, and when loading optimized defaults in Bios with Overclock in place to start a new and then immediately reconfiguring Overclock settings / save/exit you get lock up or garbled screen at boot! Also Ram Voltage Table when working in (Red Area) 2.21vdimm it does not like that at all and has been a problematic feature since it was incorporated in early 12/06/07 Alpha up to current 1/03/2008 Beta.


D.F.I..........Please read this thread and get us a worthy Bios for our boards

[Iketh]

rofl thx

[=[PULSAR]=]

okay well gave my computer a break had a 24 hour CQ duty I had to pull and system booted fine installed cat 8.1's and right now running prime to test stability. I have been pushing my setup extremely hard the past couple days maybe it just needed a break. I think I might buy a LE-1620 to mess around with.
