Hi
I am currently running the X4400+ on a DFI UT ultra-D board with no issues with the latest official bios.
A friend sold me an opteron 165 CPU which I installed replacing the X2 4400. The trouble is the Pc now wont boot. There is power to the board but everything else seems dead. No fans spinning, nothing.
Did CMOS clear and tried again. Made no difference.
Took Opteron out and replaced it with the X2-4400 again and the PC is back to normal.
From this I assumed it must have been a dead CPU so I took it back to my friend.
However when he installed it on his Abit A8N SLi board it booted up fine with no problems.Anyone got any ideas why this should be?
Thanks
AFAIK, it *should* work...but why would you replace the X2 4400+ (2.2GHz) with an Opteron 165 (1.8GHz)?? It's not an upgrade, it's a downgrade. Unless you're hoping it will be more overclockable than the 4400+?

Yeah I heard the opterons were better overclockers and I just wanted to see far It would go.

Yeah I have got the latest Bios from DFI. I even tried an unofficial "TMod's" bios from DFI-Street which is supposed to have better memory compatibility.
I know it's not a memory issue as I tried the same modules on both the DFI and AN8 boards.Works on AN8 board
I doubt it's a PSU issue either as I have got a Seasonic S12-600w.
It's not a major problem but it's starting to bug me.

But the 4400+ already has a 400MHz jump coming out of the gate because of it's higher default multiplier of 11x. The Opty 165 only has a multi of 9x. How is the Opty gonna be able to overclock higher than your X2? The board will be the deciding factor on how high the CPU freq can go.
Do the math. Let's say you can raise the CPU freq from 200MHz to 250MHz without any stability issues:
11 x 250 = 2750MHz
9 x 250 = 2250MHz

Disregarding the fact that he hasn't been able to get the X2 4400+ to boot on the DFI - despite the fact that it should work & just going by how cheap he *may* have gotten the X2 CPU from his buddy and how much he could flip the X2 4400+ for on say fleabay, I would say he made a right gamble and I could easily see myself doing something similar under the right climate.
The Opteron is definitely a better overclocker, especially if his pal sold him one of the more reliable & early stepping codes because with those he could very well end up doing 280MHz-290MHz without implementing any extreme or water based cooling solution.
The mystery is why the heck is the DFI not booting?

You Hit the nail on the head Sabertooth. My plan was to try and OC the opteron to around 2.8 - 2.9Ghz and then sell on X2 4400.
As it is my friend is prepared to take the opteron back if I can't get it to work, so I haven't lost anything.
But like I said it is bugging me. I have also posted on DFI -Street forum but still no joy.

**Turn your images on**
My 280MHz-290MHz actually translates to something more like 2.5GHz-2.6Hgz............................LOL
Anyway, it's nice to be very optimistic, but don't be too disappointed if your particular CPU doesn't scale as much as you hoped - if you are somehow able to overcome your current boot dilemma.
Goodluck & below is a table that I thought might interest you.

At the moment if I can just get it to boot would be achievement ....LOL
Thanks anyway sabertooth

Sabertooth,
He has the X2 4400+ & it apparently works fine...it's the Opty that won't boot.
Correct me if I'm wrong, but seeing as how there's no FSB to contend with, the ulimate goal is max CPU clock speed regardless of whether it's attained via the multi or the CPU freq? Since the X2 4400+ has an 11x multi vs 9x for the Opty 165, the X2 *should* be able to hit the higher clock speed, even if it can't reach as high a CPU freq as the Opty. If he had gotten the Opty 175, I'd say there's no doubt it will outclock the 4400+. But the 4400+ vs the 165? It's a tie at best. Of course, the RAM setting would play a role, so there may be concessions either way depending what the final RAM bus speed turns out to be.
tambes,
Have you tried overclocking your X2? How far have you gotten with it?

"He has the X2 4400+ & it apparently works fine...it's the Opty that won't boot."
Yeah, I realized that & the X2 4400+ reference was actually a mistype. I didn't notice it until after I had posted it and with no edit feature on CN - it's permanent.

I'm working on it at the moment. currently it's at 230 x 11 stable but the temps are upto 57c, so I'm a bit cautious to push it further until i Can control that better.

jam,
The advantage of the Opteron 165 is that they are selected from the best production batches and labelled as such, because these CPUs were primarily earmarked for the Server platform and not the desktop/workstation systems that enthusiasts were sticking them in.
You are quite right in stating that X2's 11x vs 9x multiplier should be to the X2's advantage when overclocked, but the 165 unfortunately has the ability to attain very high clock frequency than the X2 4400+, my suspicion is most X2 4400+ will top out at between 240MHz-250Mhz clock frequency on air cooling.

"...with no edit feature on CN - it's permanent."
Yeah, it would be nice if the author of the response was allowed the ability to edit after the fact.
I realize that the Opty is the "cream of the crop" but there should be no significant performance difference between the X2 at 11 x 240MHz & the 165 at 9 x 290MHz.
0
Absolutely! But thoughts of the 165 potentially pull off 3GHz stable speeds on air alone, is very tempting. Not to mention the fact that he was getting the CPU for dirt cheap, as he probably did.
I'm still miffed as to why the DFI won't boot.

The opty cost me £80(approx $160 US)
You are right Sabertooth it is the fact that the one board you expect it to work on is one that fails.How annoying is that
