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

I can not set the CPU-FID if i set the cpu multi on the genius main page here.
Can you boot 3GHz at stock (1.3V) voltage?
And to nag you albit more, have you checked the max ref Ht you can get? Mine tops out at ~270MHz where the 9600BE did up to 285MHz. (on 3-07 bios).
Also I found the higher the ref HT the lower the possible max nb frequency can be.

Let's see..., for 4th time I'm gonna try reply to you guys.

Well, here it's the same, if I change CPU multi in Genius main page, no CPU-VID in CPU Feature page. What I was trying to say is, changing one at the time, didn't affect multi after booting Windows, because I was running at BIOS default, after CLR CMOS, loaded BIOS default, so CnQ was AUTO, and affected the multi setting in Windows, setting it at 12.5.
CnQ disable I can change CPU multi or CPU-VID to 15, and booted like that.

Yes, I can boot to Windows, 3000MHz default Voltage, in fact I was able to install Vista x86 too. But now (some hours ago) I'm facing IDLE lockups, only replaying here was enough to lockup 3 times in a row.

Maximum HTT was 275 at 11 multi, very unstable, enough to boot XP. 307 bios.

^^Looks like the CPU FID option has a major bug, it's not changing clock speeds at all [bit like Crystal CPUID for NB].

His 2800/3000 results are too slow. Wprime depends on CPU clock speed highly and his 3000MHz 32M is slower than my completely non-optimized, normal windows, AV/FW/FX/CPUZ running in background ran 32M at 2800MHz: http://img81.imageshack.us/img81/1269/2800wprimeav2.png

Here's my old 3000MHz run, its far quicker: http://img208.imageshack.us/img208/465/wp323gds4.png

And I've just ran my 2828 again [NB is stock, just changed it in CCPUID before to set on boot], its still fair bit quicker than his 3000: http://img214.imageshack.us/my.php?i...primehdid6.png

Which is not possible. His clocks are lower than 2800, his 3000 result looks like 2700. You have another DFI bug to sort out

But he has a very low stock Vcore, he has a lower TDP, higher binned model which should clock better than ours.

Hehehe... Tye that runs was 1st 9850 boot, BIOS on it's default as I explained above ( I guess ), multi changed in AOD, no reboot at all.

Maybe yes, system is running slow at 3000MHz general use, need couple secs to open this forum main page, not normal.

I got some EVE stress test at 1.37v, system is more stable, at least I'm still writing
Yesterday manage to boot 3100MHz at 1.34v, did CPU-Z Validation, lockup, end of story, tried 3200MHz, system boot, Windows load fail, I didn't wanted go over 1.36v, 1st CPU day., played some HT/NB/MEM at 3000MHz, IDLE instability. Went to bed, getting pissed off, grrr...
Gonna play a little more today.

Actually AWARD Flasher 8.83 is the recommended one from RGone and I agree with Robert on that one and its been hard road getting that figured out through trial and error on my end.

Have you or RGone test 8.87? 8.83 it's OK too, can be used /f command, 8.90
Have you more info about temps at 1.25v?
I haven't read all the new posts, just went straight to here for reply.

Nice load temps.
Are you using the bios in your Sig?

Anybody know if the DFI 790FX-M2R will work with a cheap $32.00 Sempron? The 790FX boards from other companies say they work with a Sempron... but DFI doesn't say anything. (But they don't say anything about using 1066 memory either.)

I'm considering ordering one of these as an "emergency" backup CPU. "Just in case". If I get my Motherboard back next week and the Phenom I have ends up being what my problem was... then I'd have to wait for that to RMA. In the meanwhile I could get a 2.0 Ghz Sempron for $32.00 and get it at about the same time that the motherboard comes back.

If the phenom works okay (which is my HOPE) then I would have wasted $32.00. On the OTHER hand if the problem IS the phenom... then the $32.00 would pay for itself immediately. (Since I wouldn't have to replace my old motherboard/cpu/memory yet again.)

So it would be kind of like "insurance". If I order it... then the laws of nature would say that it will be un-needed. :-)

PLUS as a bonus... I can use the Sempron with a small cheap motherboard and some cheap ram for building a multimedia server.

If its the same socket it (should) work. should being the operative word here

Nice load temps.

Yes I am currently on 1/30/2008 Really don't understand enough or am unfamiliar with Phenom so Flashing Bios when you don't know whats normal and whats not is not a sensible Idea and not very bright at all even if I can reprogram the chip on my end I need a working Baseline on which to Judge other Bios on.

Just ask, because was thinking to give 130 a try.

Appreciate the offer aGeoM So far I like this Bios with the Phenom but with my 6400+ BE it was just ok and not as good as 11/22/07 and the 3/12/08 Beta were but none the less good

With Phenom its a really nice Bios from what I see so far but also I have not really challenged the HT Bus deal either. Actually it appears that HT Clocking is kind of pointless on the Phenom seeing how you can manipulate the HT / CPU /NB all independently which is really, really nice by the way and jam on it that way But I suppose HT still finds its merit and worth in being able to incrementally increase and fine tune your clocks CPU/Ram/NB and what not But I really like the Phenom and it really rounds off the experience on this board quite nicely and Gaming is much more fluent even at stock compaired to My Q6600 @3.55ghz and 1186 on Ram now thats impressive Cant complain at all man not at all

You are working on 130, me and justapost on 307, and Tony on 331, 3 front lines.

Well... just finish for today, updated 3DMark06 ganged/unganged memory setting, had some Phenom love, I'm happy, I can go sleep now.

Didn't try Gaming on 9850, must install my favorite game ( Americas Army ) to play a little tomorrow, it's a good game for testing CPU too.

Cya guys, be well...

Brother, I hear that quite often from people both having an AMD and Intel setup. So guess that's a good and solid statement then

Anyway, I ordered a Phenom 9850BE, hopefully it will arrive today.

I asked this in the 790FX-DQ6 thread however no one seems to care or so.

Is it possible the IMC on my X2 is degrading or so? A few weeks back I had those strange crashes etc while my memory was allright. Turned out I had to downclock by 30Mhz and it was all good again.

Then this week I got them again. This time I thought it would be the memory (D9's), and I tested them with lower multi and they errored. However I wanted to be 100% sure and changed the DIMMs for one OCZ ReaperX PC6400 (two won't fit lol). Tested the CPU again at the 14x249 and it still BSOD'd. So it wasnt the D9's after all, since the IMC is linked with CPU speed and controlling the memory I think it might be the IMC dieing slowly?

Ill drop the CPU into my 790FX-DQ6 board today. It does have a broken 4th DIMM slot, but as long as I stay away from that it's ok. If I can get the CPU stable again on the DQ6 the problem must be at my M2R, however I really have the feeling it must be the CPU.

Any ideas? And even better, how to prevent it from happening next time.Temps never got over 50, and I only tried a very, very few times at 1.55V to check if I could OC further in the beginning.

Well, in this case I hope it's the CPU.I still have to RMA the DQ6 because of the 4th RAM slot. If it's the M2R, Ive to set everything over into the DQ6, RMA the M2R and when I get it back again change evrything over again and RMA DQ6.
