perc: so it doesnt boot at all? what about the psu or memory? is evap making good contact? you may need to remount it esp. on a DTR

yeah i think i need to start over with this sytem. im going to rip it all out of the case and remount the damm mounting kit and pray like hell i can get it going. the more i think about this the more im convinced its not the cpu. i think its a cold boot issue cause when i first built this system i wouldnt boot just like its doing now. i think that at auto the bios is setting the v-core at 1.04v wich i think is the cause of all this but im not 100%sure..i have a spare bios chip just need to hot flash it in my intel rig. i hope that maybe a diff bios i may be able to get jump started again... ill keep you guys posted on how it turns out. thx for your replys guys.



peace perc,

Is my A3400+ NC dead too?
Or is it something else?

I am running my ADA3700AEP5AR 0432 at 3ghz / ~1.8v. With 3.3v @ ~3.7v, 5v @ 5.2v, 12v @ 12.4v on the PSU(OCZ520W), vDimm @ 3.5v, and I haven't seen any problems so far. I have the DFI UT and AFAIK there haven't been any problems with the DFI and these failures, right? Is this a s939 issue only?

Only problems I have had was two dead DFI boards. First because of a 10 minute blackscreen limbo, caused by a 3.15ghz suicide run. It simply froze and I wasn't around to shut it down, 10 minutes later I return, the board never posted again. Second board died because of OCZ Booster, 2.8v read by the booster, 2.8v set inside BIOS, no OC on CPU @ 1.5v - worked for 12hours stable, then booted PC and black screen, board dead. I'll never, ever use the Booster again on a DFI UT. First board RMAed, I bought the second one(didn't even tried to RMA it). Lucky for me, the CPU has survived all of this and even more.

Is it for real, when AMD says no more than 2.6v vDimm is recommended? This can't be true, and the OCZ guys said they have never seen a dead CPU from high vDimm, but I wonder about the 3.3v rails.

I have seen spikes on the vDimm, but that was from reading the BIOS' readings, and I have been told that the DFI UT' voltage readings are attrocious. Another funny thing is, that sometimes vDimm voltage readings don't change in BIOS after a bootup.

It can be at 3.5v and I change it back to 2.8v, but after reboot it still says 3.48-3.5v as current vDimm. Only after another reboot, will the reading be correct, but still fluctuating up to +/-0.2v. I have had this issue with all three DFI boards. Anyone know anything about this?

I don't think I'll ever have a problem with my 3700+, because of the 3.5v vDimm or my 3.7v 3.3v line, but I'll report back if I am wrong :p:

up....is this still an issue??

I think this issue is way over exaggerated... I personally haven't come across any...

You probably weren't around when the Shuttle AN50R was "hot". :stick:

so has this issue been resolved? for Socket 754

personally i think i will stop at 1.65 vcore and 3.1 for vdimm....but thats just me... :)

is this still a problem?

If breaking CPU's with too high voltage, or by some abuse is a problem, then yes it is a problem. :D

Holy-chip!!!!!!!
Now THAT was a long n scary read, yep every post on all 11 pages!
I've been sitting on a A64 3000+, K8NS Pro and 3X512 since X-mas.
I did put together the mates to the cpu and mobo X-mas day for a former boss of mine,
He's had no problems other than slow boot, my quess is the not-brain wipe,(reformat)
he made me do cause he didn't buy an extra HD, and still won't even @ these current prices and his made some serious sounds back then!
Dam non-gamer's!!!
make us look crazy for needing newer n better when they can run with crap cause all they might do is pictures n type stuff!!!
Anyway I'm about done with "SUPER COMPUTER" Multi-loop water n chilled water system and did a search for my board and found this thread!!!!! Dam!
Well....
Its good to have extra puters and parts I quess.
Just hope I got a GREAT chip, cause I can remove some serious HEAT!!!

Yes,
I will be water cooling the chip-set, also the RAM and PSU as well, (Multi-loop)!
Thats because I can and I did the research!
Thanks for all the info in the forums!!!!!! cheers 2 all who post, good, bad or just a question!
Thats how this information super hi-way makes us all better!

Good DAY/Night

my cpu been running at 1.72vcore for almost 9 months now on AIR - and it aint dead :p:

it doesnt need 1.72v for 2.6ghz (more like 2750mhz) but i dont like changing the voltages too much.
