I've been overclocking my Opteron 144 and currently have it @ 2.4 GHz. Temperatures are around 25C @ idle and havent broken 40C under full load in Prime95. Anyway I ran Prime for 54 minutes to be exact then restarted and went into the BIOS to try 2.5 (276x9). I set the divider to 140 (7/10), then saved and exited. After the initial screen when I press delete to get into the BIOS, where it usually says something like "Backup CMOS....... OK!", it said nothing and just rebooted. Have I hit a wall w/ my 144 already?
Could I have hit a wall ALREADY?

As unlikley as it may seem, you could have. I got the BEST stepping of opty 165 there was out there, got to 2.2GHz and hit a wall 
. Slapped my dad's opty 144 in and it's stable at 2.8GHz in the same system. He's got the 165 @ stock right now.
TIP: Set your ram divider to 1/2 and try.
TIP 2: Also, set your ram to the default settings manually. Never trust teh mobo. remember to set ALL the settings to stock, including voltage. Don't leave voltage or latencies or anything ram related up to the mobo to decide. My mobo thought my OCZ DDR-500 3-4-3-8 with 2.8V was supposed to run at DDR-333 2-4-3-6 with 2.6V :shocked:.
TIP 3: DFI mobos = crap. I had TONS of problems like that with mine when I had it for a week. RMA'ed it and everything is good now. As a matter of fact, I think I remember that excact same message coming up. If nothing I said helps, RMA your board and get something better.

Why not take the memory out of the picture completely and drop it to 1:2 with slow timings. If that doesn't work try a CPU multiplier of 8x just to make sure the board works ok with that HTT freq (drop the HTT multi to 3x). If relaxing the memory doesn't help and the board runs fine at that same HTT freq with a lower multiplier, then YES you could have already hit the max. Of course, you also haven't mentioned the voltage you're giving the cpu. Those temps sound like you're using great cooling or lowish volts.
I'm still @ stock volts (I think its 1.40v). Someone on another forum recommended increasing the voltage to 1.45, I'll consider that. Right now, however, I cant do anything because its time to go to bed.
UPDATE: Tried it quickly, boots fine @ 276x8 w/ 140 divider, so it appears the CPU is the bottleneck.
Sounds like it's time to up the volts then. I'd still consider a lower memory speed while you're trying to find the limits of the cpu. Goodluck.
pump some more voltage and change the multipliers... some motherboards do not work with certain multipliers...i do not think u have hit the wall 144 are supposed to be good oc
May be time to bump the chipset vcore up a notch since you are starting to get up there in terms of HTT...The single cores I wouln't be afraid of taking up to 1.54v easy.....My 3000+ ran 2.66ghz with 1.54v for nearly 9-10 months no problem....Runs a more relaxed life in my 6 year old sons computer at 9x270 2.46ghz and 1.36v (board undervolts slightly)....
Yeah, mine's one of them. On stock volts I dont think it goes above 2.2. Does 2.5 on 1.55v & 2.6 on 1.65v, not that I'd recommend the latter for long. Some might say 1.55 is too high but remember its only a cheapy 144 so what does it matter if it blows up in a year? Crank up the voltage & get the most out of it now I reckon.
Duvie - FSP are Fortron Source fsp-group.com. They make pretty good psus from reviews I've read so that shouldnt be the problem although 450W is a little on the low side for an overclocked system perhaps? Perhaps that's my limiting factor too?
No way I'm going up to 1.55v voltage. I'm not sure if I'll keep this CPU very long (want to get Opt 165 as soon as I have enough money), I dont want to risk killing it.
And really noobish question question here- how do you up the CPU voltage in the BIOS? What option should it be?
You wont kill it at 1.55v....Is the opteron 144 a 1.4v default vcore?? If so 1.54 would be the 10% rule...I have never seen a cpu die with only a 10% increase in vcore...PERIOD....I have been doing this for quite sometime now....
My 430 enermax was able to handle by 3000+@2.66ghz so I think it could be fine....You do have a much bigger powerhog of a vid card then I did so it could be right at the cusp...How many HDDs???

Duvie is right, 1.55v wont kill your cpu. I was being dramatic before. It may reduce its operating life slightly but not so that you'll care - you'll have upgraded (several times probably) long before it gives up. I'm afraid that with some cpus, unless you are prepared to bump up the vcore, you will hit an early wall. It's the luck of the draw.
Its called "CPU VID Control" in the "Genie BIOS Settings" page. The DFI has a seperate option for startup which allows you to set it lower to get past the POST stage if you have problems booting. I dont even have this board but I really wish I did. My next purchase I think.
I'm working from memory because I'm on my other PC now (still havent set up Internet on it yet) but is it that thing that has %'s.... such as 104%, etc..... so it would be 1.4v x 104%?
That's the CPU VID Special Control which is for increasing the voltage above 1.55 (not recommended). The CPU VID Control allows you to go to 1.55 in 0.025v increments. Leave the CPU VID Special Control at Auto unless you want to go higher than this. There are screenshots here http://www.techpowerup.com/reviews/DFI/LPNF4UD/6
Up the voltage. My Opteron 144 does 2.8 Ghz at 1.440V actual (I set it to either 1.45 or 1.475V in the BIOS; I forgot which one).
I think I'm done with this overclocking crap- I'm just going to have to live with 2.4 GHz. I tried raising the VCore to 1.425V, just to be conservative, and the FSB @ 276, and memory at 7/10 multiplier......... not only did it still post nothing, I heard a loud "beeeeep" from the system and it restarted. I went into the BIOS, and everything was back at "stock" settings, FSB @ 200, RAM multiplier @ 200, Vcore @ 1.4v, etc. Kind of scared me there, so I think I'll go back to 266x9 and just live with it. No game doesnt work well w/ an "Athlon 64 4000+" anyway, so I shouldnt be concerned. All this overclocking crap is OK, but I think when it gets to increasing voltage, etc, it gets into more of a "hobby", than just to get better performance out of a cheaper chip.
You give up too easily.
Edit: Did you try raising the voltage in the "CPU VID Startup Value" as well? Have you lowered your HT multiplier to x3? Have you tried a lower, more conventional memory divider (e.g. 133)? Have you tried a higher vcore? Have you read an overclocking guide?
BTW, please dont come onto an overclocking forum and tell people their hobby is cr*p just because you dont have the savvy or patience for it. Why did you bother buying that board & cpu?

Well excuse me, but I want to overclock and I think with a chip like an Opteron 144 its an amazing thing to be able to get $300 performance for half the price- like I said, it's just not worth doing something like increasing the voltage to get 100 MHz out of it. For me, overclocking further, even trying it, is pointless. I see no reason to do anything that could (potentially) harm the CPU just to get that 50 points out of the 3D Mark 06 CPU test.
On my first OC with the 144, i hit a wall lower than yours at 1.4V but i'm running 1.45V 2.55GHz. If i take the VCore all the way to 1.55V i can hit 2.7GHz. Try using a higher voltage to test it out at least, i was scared at first but it's fine really. I got a bad chip too.
