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:yepp:
^ No there aren't, Campbell is telling tales now guys, beware.. it's just DFI, only DFI :yepp:
Only kidding, Camps right :D
^ Ubuntu X64 is even harder than Vista X64 to oc, trust me :(
.... 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)
edit:
I have just found this, and i am very scared....

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. :yepp:
can certain Phenom models get 3ghz on good water easily or no?
my cpu can get 3.0 with no voltage tweaks at all... just boom!! 15x multi stable
Very good result for 9550 there sea_man :toast:
Exact same parameters including voltage are my past favorite setting too with 9500.
railmeat: yes, and above.
:yepp: Except HT/NB multis @ 9.
My RMAed 9850BE arrives tomorow, meanwhile...

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

I will order in the next week an Crosshair II, and keep this DFI/9500 combo, for my collection :rofl:
Time to :slap: an AMD engineer and get them to fix it. :bsod:
Quite dissapointing native 64bit processor does not work well with 64bit OS:shakes:
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 http://www.xtremesystems.org/forums/...ons/icon11.gif
BTW, I have 2.8G stable in 32b and 64b, not tried more yet.
aGeoM given up on the 6400BE ?
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.
Oh jeez I see how this is gonna end up already:rolleyes: @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:yepp: 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:clap:
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.
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 :D
:idea: :oscar: :welcome:
I would like someone to post all of their m2rs bios settings with the bios version.
I cannot get mine any higher and i know i can. Im trying to raise voltages and stuff to get it higher but all they do is add more heat lol.
Even with 1.48 vcore i am only at 35c
gimme gimme :)
thanks
:rofl: I'm not, just sold my 5000BE+250 HDD+80 euros(beer savings)=Crosshair II :up:
:yepp: now DFI/9500 is 2.8 stable (Benching+Gaming+Surfing+Prime) WinXP x86/x64, Vista/Server2008 x64.
Never had one, but no more Duals for me :p:
Sorry if that came off a little harsh, I was more just trying to :poke: for a little info on your clocks. Above, you answered my curiosity. This is a well informed board with a lot of power hitters, that I respect. :up: I look at sigs as a reference, it puts a personality with posts making a persons post mean more. I change parts every month so I'm updating regularly. (BTW Nothing free here, internet sales pay for these :yepp: ). I certainly hope it helps people to know where I stand when I answer a question or post a result.
I did some reading from AMDs tech pages, these little power munching beasts are seriously complicated with a lot of parameters to keep then moving. Some of the settings for the RAM could easily take it down if not tweaked right. I will read up on it when I have the time. I now see where some of these timings are coming from but I'm not up on what to do yet. Might be some tweaks in the NB and DRAM controller that will help.
No problem :)
It's quirky to work with Phenom trying to get it stable.
My update: http://www.xtremesystems.org/forums/...postcount=1840
Hit post there before here, so might as well. :D
Not 64bit though - that's on a different drive and fudged up with 800x display size.
I'm running 800 RAM, its much more stable and is the only way for me to avoid C1 errors at boot. Not 800 mode but actually 800 rated RAM and not 1000/1066 rated. Everything else but CPU multi is at stock.
AMD hasn't provided drivers for lm-sensors but they did say they're coming, so we'll be able to get some info through them. I can't get CPU frequency scaling or changing to work for some reason, it did on older CPUs.
See this, in WinXP 32b, this is easy for my 9850: http://www.xtremesystems.org/forums/...&postcount=935
AOD full load for about 2 hours starting from stock, this is what it finds stable->
Whilst working: http://picsorban.com/upload/au2.png
Final max stable: http://picsorban.com/upload/3055.png
These are my current settings, multis, voltages and VIDs that I've changed are all there (Sandra Java benchmark):
http://picsorban.com/upload/mt-ar-2.8-2.4a.png
http://picsorban.com/upload/mt-jv-2.8-2.4b.png
But... now for a Mesonychoteuthis hamiltoni sized spoon of reality;
None of those are truly stable apart from the 2.8G setting which I'm still testing! :mad:
Yes yes, the normal trash happening: easily bench/load stable, freezes idling or during common tasks. The critical freezing period is anywhere between 0.1 to 28 hours.
And yes, the normal drum of Prime95, Sandra, EVEREST, OCCT, AOD, Systool, CPU Stablility Test, MaxCPU stability testing all fail, none catch any errors in this stability range; something we found with the first B2 9500, mine could bench 2832MHz easily and repeatedly but below that was showing the same freezing issues all the way down to 2615MHz.
I even ran FAH and WCG for 24 and 5 hours on the 2.975GHz setting about 5 weeks back on stock cooler without TIM just to see how good they are for catching Phenom B3 errors with an overheating core, but none of those really test stability anyway and as expected, even they fail to find any errors. They're just for higher than average heatloads, my B2 and B3 Phenom intentionally at an unstable setting ran WCG fine for 5 days and that setting failed P95 within 20 seconds.
As a brief recollection of the ones I tested, my unhappy findings;
9500 = 2860MHz max - 2832MHz max bench - 2772MHz max load stable - 2615MHz max fully stable
9600 = 2622MHz max - 2599MHz max bench - 2553MHz max load stable - 2553MHz max fully stable
9600 = 2599MHz max - 2553MHz max bench - 2530MHz max load stable - 2530MHz max fully stable
9600BE = 2560MHz max - 2525MHz max bench - 2500MHz max load stable - 2472MHz max fully stable
9600BE = 2940MHz max - 2849MHz max bench - 2805MHz max load stable - 2656MHz max fully stable
9850BE = 3155MHz max - 3100MHz max bench - 3059MHz max load stable - 2700MHz max fully stable [still pending]
All the ones having a different max load stable to a max fully stable showed idle freezing problems.
So I'm left trying to figure out what is causing them all this "idling" instability, why and how to avoid it -- so far with multiple Phenoms, I've not found a way, on all motherboards I've tested and on all the CPUs, the problem existed. I am trying to cut it down and work things out, tested everything but the following; either to do with MRL of DRAM or the NB volts needing to increase as you increase CPU MHz [as Achim found]. I might have a Toliman soon to see if that also has it (or is it that core3..), depends on time.
Only one I recall never showed the freezing phenomena was ASUS 790FX and I've not heard anyone on that board report it either.. but my time with that board was very limited and short, since they had poor early BIOSes.
Interesting KTE.
I thought at least about MRL... I think for example since the MRL can be variable, we shouldnt use Memtest since that forces the crrent applied MRL. Although if MRL doesnt change during uptime it's not an issue, but if it does change will PC is on it's a bad idea.
I think also there's something wicked going on. And it has definately something to do with Voltages and NB is very suspicious too. I downclocked NB to 2.2Ghz and set both CPU and NB to 1.35V and got a freeze in about 10 minutes 24/7 usage... That's just like impossible (was running 220HTT, 12.5 CPU multi and 10 NB multi).
Also if you didnt read this yet:http://www.xtremesystems.org/forums/....php?p=2957907
Might be interesting that it might be the SB600 causiong this stuff. I mean, in general freezes are caused by just a notch of Voltage short. If it's too less Voltage it either wont boot or BSODs (AFAIK?). But this freeze... what about just something causing instability. And since we see it almost on every board and Phenom this might actually be true.
KTE, did you try the Phenom on a 780a chipset yet? I wouldnt like to get a 780a though since Im running CF. But if it was just to check if it's an issue with SB600... Not a lot of people have the 780a yet and AFAIK everyone who suffers from freezing actually runs a 790FX board. Though it's strange the Asus one doesnt seem to suffer from it. They dont use reference boards though, but so doesnt DFI.
Also, KTE, those REAL stable values, did you notice that the NB had to be at 2Ghz or was it afterall the CPU speed what caused the freezes if over a certain point?
I've kept the NB at 2GHz all the way, just to eliminate all factors. Usually I run 10x, 11x and 12x on NB at each setting just to check.
2.4GHz NB didn't freeze any quicker than 2.0GHz did at a idling instable settings.
Voltage - if it Primes/EVEREST tests and benchmarks fine, then something is iffy and something other than the CPU itself can be the cause, very possible. You have to have those basics in place though.
I've not played with a 780a yet, nope. Wanted to buy ASRock 780G for home but I just missed out, they sold out within 24 hours.
MRL - reason is this. At times I have booted low MRL and had higher bw then at other times. When I was testing across BIOSes and boards, the first thing I tried to keep the same is MRL, due to its high bw effect. Problem was, at the exact same settings and hardware but on a new bootup, you may not be able to get the same MRL value back without crashing. Hence it "could" be a cause for some people.
For me, I doubt it. I've tried upto 62 MRL at 800, which is high enough when stock is 51. The freezing continues... :(
Oh well,
As you can read in my sig Ill wait for the SB750. Im done with this crap really. Im around 2.65Ghz now and will see how that performs. If it's stable Ill add now and then 1Mhz to HTT. Since this is my 24/7 system as well I prefer stability a lot lol.
If SB750 launches and it proves to solve everything Ill be the first one in the line to get one for sure and do some new testing. But atm we're just 'fighting' something about we dont know why and what exactly causes it to be instable.
Woe, might have something there :idea: I have a 9500 that was a pain on the GBT790FX dropped it into the ECS740G and it is rock solid with Vista 64, albeit stock. I never saw that stability on the GBT. I did tun the 9500 on a 770 board w/SB600 OCed to 2.39 for months but the it started acting up. About that time I got a 5000BE and replaced it.
What is interesting with the 790 and SB600 is that when I see the crash, it's at a point of loading an app or booting. I'm still at stock with folding running 20 hours a day while I surf, watch Vids etc. I shut off folding when I run the 3D stuff and games. Ran 2 hours of gaming and some simulators then put back up to fold. It's been solid with no issues now for 2 days. I'm going to go for 2.7G and just leave it there. The only problem I keep seeing is that it boots to 2.5G even though I have it set on X13.5. X13 does the same thing. Is this related to the C1 error?
I can't unhide these, DFI have added so much of their own code it would need a direct hack to get this to show...thought I would share though ;)
Is this something new on the way with Phenom ?
http://www.ocztechnologyforum.com/st...ram_speeds.PNG
interesting that would be really nice wouldn't it :D
Are you OCZ people planning something incredible with DDR2 ?Quote:
Is this something new on the way with Phenom ?
That DFI know about, 2048 !!! and I've just ordered OCZ 4GB PC2-8500 Reaper HPC (2x2GB), from Aria, knew I should have waited.:rolleyes:
Officially it supports DDR3-1600 max already.
Hehe, physically the circuitry is not wired up though :D
I discussed with some MEM MFG workers when 9500 was released if I could mod the sockets to try DDR3, the answer was just no. :(
I have a feeling we may see 1333 from DDR2, i never expected for us to see higher ;)
Just weird that this bios had the options and earlier builds did not...
I will show you all the voltage options they have hidden next...if only modbin worked LOL
Based on DDR2-800.
DDR2 works from 100-200Mhz at the circuit level and dual multiplexed in the DIMM module meaning one signal access 2 chips. one on the even cycle, the other on the odd cycle. The chips still operate at 200mhz but the multiplexer handles it at 400.
Based on DDR3-1600.
DDR3 works from 100-200Mhz but is quadplex or 2x Duplex. This adds an extra cycle to the already double data rate which quad pumps the IMC-DRAM link. The chips still operate at 200 but there are banks four on the DIMMs sharing a single lane which is effective 800.
Sneaky way to get the speed but it works because it fattens the pipe where the bottleneck is, getting data loaded into the rows and columns of cells.
Bump the base line by just 66mhz and both go from 800 to 1064 and 1667 to 2124 respectively.
2*266 = 533 or DC 1066
4*266 = 1064 or DC 2128
new spi1M personal rekord over here :D
I`m glad if you share the complete config for the 9500@ 2.8 ( volt , and other settings)
and few question....
1-in the phenom is necesary the NB and Vcore volt are equal ?
2- what is the best method to cooling the chipset an PWmic ? ( i have 44º Pwmic an 49 chipset , in idle..... i fell is to Hot..)
3- is correct the temp showed in the smart-gardian ?
Thanks.
uhmmm.. well... was planning to use a lab chiller for some more oc and/or replace my grafics cards with a pci card to get some more headroom on the 12v lines...
but "unfortunately" weather was too nice that weekend and after looking at that chiller i had in mind i'm not sure whether that thing is gonna cool that 200w away... will try both things another time..
Hi.. new results at 2.8
http://service.futuremark.com/compare?3dm06=6536674
the bad news.. i need 1.431 vcore to go to 2.8 :(
but whatever very nice score...
some dual-core related experience with the 05/05 bios so far??? thinking of flashing/trying out that bios so far..
I'm so with you. This whole thing is just a shot in the dark, there is no predictability at all. I'm gonna unload all my stuff, and downsize to another Gigabyte 780G board and a single X2 card. Might even do another BE5000 to be honest. I can't see ANY difference in gameplay with the 5000 and the 9850 (other than ridiculous random crashes!!).
The rumored SB750 OC benefits are still not enough for me. I have no idea if that will be stable or not. I can't even get complete stability with the 9850 STOCK. So something is rotten in general. I have no problem doing some tweaking and messing around with settings and hardware, but now, basically, nothing really works as intended.
This whole craziness that we all have seen where you can test and bench and stress all day and its rock solid, then it blows up in menial tasks or gaming means there is some underlying mystery that is either unsolvable, or someone somewhere WON"T solve it (nee, AMD). Its their chipsets, their processors, their GPUS, their drivers and THEIR FIRMWARE. Its ALL them.
ok got this board, phenom 9850 BE, 2x 3870x2 cards and no boot whatsoever...can this not support phenom out of the box...do i need to get a am2 processor and flash the new bios?...the video cards stay with 2 power led lit like there is not enough power, but the board does not boot even with crap hd 2400pro card...any input is appreciated...fast :D
try a proper cmos clear.. used or new one or open box??
bah nevermind i just hit reset 2 times and is now booting fine :)
lol consider a bios update whatever...
i have been AMD through and through since the early/mid nineties, dabbling with Intel stuffs every once and awhile along the way, although with the Intel, not much recently, except for a couple of Intel Core Duo lappy's....these phenom problems are HUGE concern in my world, it seems AMD has taken a step BACKWARD in an effort to catch up....
sticking with the 6400+BE and the DFI 790 board for now, board screams with a dual core, no problems at all...Phenom and four cores can wait for awhile, or forever:mad:....
laterzzz.....
Well I have not had Issue one with my Phenom 9850 BE @2.8ghz @1.23750vcore:) No Random Freezes , Shut Downs , Instability , etc , etc;) and I run my system 18hrs a day mostly 24/7 though:)
so how do i squeeze more out of this cpu?...i got M2R board, 9850 BE, ballistix tracer 1066...what settings do i need to modify, cause at stock the cpu crashes at 2.7 :S
are these cpus really such bad overclockers? :(
thanks for any info
why don't you try posting in the DFI / Phenom thread that just has people using Phenom with out board?:confused:
guys a quick help , i am looking for Sapphire bios to update my 790fx motherboard but cant find it anywhere , is it sapphire works straight out with DFI bioses?
Sapphire bios page doesnt even exist. please help me , is it ok to flash the sapphire with the latest dfi bios?
You can Flash with DFI Bios PM JustaPost and ask which one please:)

Bump!
I upgraded the cooler on my Phen but I'm in the middle of some development so I've not had time to play with OCing. I also dropped a Corsair 550VX in so I could have the EPS610 for my Quad socket.
While I've been working on projects, a bud on the OCF forum PMed me that he has a Toliman running 2895 at 1.28V with a biostar TA 790GX A2+ (SB750). I feel pawned!
I'll be getting back to my DFI and 9850 soon!
im thinking of building a new system around this motherboard my current psu is a OCZ Powerstream 520w im gonna use a ati 3870 and 2 harddrives a burner and 4 fans, my question will this power supply work ? iv read threw many posts that the DFI boards really need a good psu anyone have experience with using these together?
thanks..
normally that psu should work, but regarding a phenom and ocin a lot it "could" be too small.. depends on which processor and how much oc on graphics cards and cpu i think.. but i would try it. ocz psu's are good choice with dfi normally..
im not goin phenom just yet i got a deal on a x2 6000+ ($50) , as for the gpu im goin to try and squeeze as much as i can out of it air cooled....
jep i think then that psu should work..
:banana: just wanted to report got my board back from rma, everythings working like perfect even the nb fan header which was broken (no sense/control) does do it now.. Although the dfi support wrote me it isnt supposed to work and so there was never anything wrong with it :rotf:
best thing: one day shipping from rotterdam/nederlands to lueneburg/germany.. almost unbelievable :shocked:
now i'm cooling the pwm section with a 70mm cooler and will mount the transpiper to the southbridge... and never ever uppen the pcie clock again (as it is not necessary really.. ;) )
Hi!
I have the DK version, and I can't find the NB VID option in PWM Control menu. Is it only available on the UT version? :confused:
I wanted to test NB/L3 overclocking but I can't raise the VID.
unfortunately, best i could do with my SB600 and my particular chip is 2.8GHZ @ 1.2625 VID and 2.2GHZ NB @ 1.325 VID, ddr2-1066 (533) @ 1.9VID. i can get 2.9GHZ load stable, but i get freezes. probably due to the SB600. ill let this sit until deneb and or a dfi ut sb750 board, and then partake in the games again.
pc is blazing even at this moderate oc. i see a significant improvement over my dual core on socket 939. i can encode a ~2.5hr move in about ~9-10 mins one pass, multithreaded. superpi is 28.3 seconds.
Hi
I got an DFI UT 790FX-M2R
Does anybody knows if it's possible to run an X6 ore 4x4GB DDR2 on the motherboard?
a) I have a M2RS mobo, and the BIOS support stops to AM3 X4, just have a look here:
http://www.cpu-upgrade.com/mb-DFI/LA...790FX-M2R.html
b) You can run 4x2GB DDR2, but your mobo must support ECC DDR UDIMM/RDIMM in order to be able to run 4x4GB DDR2, which I assume is not the case. There are some Asus mobos with ECC support.
Even if that site doesn't indicate, for the M3H5 (ddr3 version of the M2RSH) both full size and JR mATX there were Thuban compatible beta bios (D7SD707 was the last Thuban beta, while the last stable D7SDA09 only supported up to C3 X4), but they had some problems with turbo and it was very easy to get them to catch fire with blown PWM on a OC'd X6.
For the M2RS/M2RSH (SB750), IIRC even if it was a very similar board, it never received that beta x6 update (and the M2R had even less support, I don't remember if they can even cope well with C3s). But at the time, at dfi street/club someone had a x6 on a M2RSH with a modified bios, so at least on that board it might be possible for someone talented.
I don't want to use an other Motherboard because i want to Build an Retro Computer with the last UT Motherboard from DFI
The Max Support of X4 is not a Problem for me And i can live with it
But 4x2GB is not much for W7 And so I only can Build it with XP64
And now i serch a way to run 4x4GB of RAM
DFI was great...Today is for me "new DFI" ROG boards. Nice to see some new photos of DFI setups :)
Oh dang, the first 16x pci-e slot on my DFI 790FXB-M3H5 bit the dust after 7 years of use, so I'll have to do without the SB Z, because the SB750 USB ports are so crappy that I require the usb3 controller on the u3s6 for an hi-power usb wifi adapter (on heavy network loads all usb devices disconnect temporarily). Since I put a 7970 early in the year I've noticed that it was running at 8x only on that slot, now it doesn't work even for 1x cards. Awaiting Zen, can't justify to buy a replacement board.
