sounds very familiar to me - allthough I´v fixed the problem by not keeping DMI data.. very odd actually..:rolleyes:Quote:

i killed my cpu last night.. first my board in 43 min 2 days ago, rma for new board then my cpu after a couple hours. i booted up to bios and noticed 3.78 on the vdim.. oops.. i must have tutrned the vr wrong way. tunr off. disconect pot, boot back up into bios. turn the pot which would be lowiring it, touch it to ground poof. off goes comp. hmm thats wierd i say. check the the pot and it was at 1.0 wonder how much volts that was? to many i guess... doesnt boot up, rma'd both. so ive killed a mobo and now ive killed a cpui/mobo (dont know which but i suspect the cpu) sent back both anyweays, replacement in a couple days.
3400+
AN50R
Have you posted it yet? On another thread?Quote:

You people, well Opp, Mr Ice and Bowman must be made of money if you can go through 6 A64's and still buy more !:slobber:
I would be extremely happy if I had one A64!
Can anyone donate a A64 to a poor college student? I would be very greatfull! :D :D
are you that good of a guide...LOLQuote:

it may be worth it...you may get a pm from me in the spring..i need to get my 21ft stratus back out on the water...LOl:D
as far as the stepping on the ones i have murdered..here goes.
3200's
caakc week 33 still alive
caamc week 43 brown
caamc week 41 brown
caamc week 39
caakc week 30
caamc week 42
lost a 3400 but i cannt find the stepping..i will look
they all died from the chipset mod on the chaintech..i am sure..
it was running 2.2v all the time..i had forgot i had it that high...
it is directly tied to the hypertransport and mem controller..i havent had any trouble since i stoped using the chaintech.
Me too. I am afraid the tires on my trailer are flatspotteed from sitting in the garage for 2 months! I would take you just for a chance to pick your brain, but you could throw in the dual evap if you wanted too! heheheheQuote:

as
Is this related to the Inductive heating problem and are there hot spots within the memory controller? Is this related to the SOI layer? Have there been any nonmemory modded processors failing? how many?
I killed a 3000+ (week 29) and a 3200+ (week 47)so far.
I removed the Heatspreader from both CPU's.
The 3200+ produces memory errors, ( Vdimm was @ 3.7V )
The 3000+ does nothing anymore.
I don't think high 3.3V rails kill the CPU's, cuz the 3200+ died on a shuttle an50r which needs no PSU mod on 3.3V.
.
I'm thinking it could be the high Vddr that is killing all those A64's,
Maybe there's a simple solution to it:
On my k8v a thick trace is going to the cpu from the mem that is reading the same value of my Vddr. Is it possible to cut this trace and put a wire on it (on the cpu side) that gives 3.0V to the memcontroller on the cpu?
The 3V could be generated from a second psu or from a self build circuit with a LM regulator.
I'm thinking moreso that it's mainly to do with the NF3 boards. As I've yet to see anyone killing a CPU/MOBO with the K8T800 by running a high 3,3 line or high vdimm.
Correct me if I'm wrong please though :)
YoupY:
Your idea doesn't seem bad at all, but considering all the excess work to even get that done I would rather just kill the board and RMA it :D
Seems like I got a good stepping from newegg for my A64 3200+,
CAAKC week 37 :) wish me luck :toast:
I wish you luck :toast:
Those are quite some frightning stories, but there's not so many chance that I'll run my cpu up so high... (haven't picked up an A64 yet, but planning to...)
so its a weak point in the nf3 design? guess it has to do with the vmods as mm suggests...
I killed my first A64 3200+ on my an50r
i got the stupid blue screen error of death when trying to boot into windows.
I tried two different hd's, had no luck.
i had my chip at 1.66v and my vdimm at 3.6v
my vdd was kept on auto the whole time.
Im thinking its my vdimm that killed the chip.
I have 2 questions:
1) Has anyone killed one WITHOUT doing the vdimm mod?
2) Has anyone killed one on a VIA chipset?
1: I believe Bowman has
2: dont think so yet
:-)
MickeyMouse your idea worked perfectly, only reason my CPU died was cause of my stupidity.
I did the mod so perfectly, I was so proud of myself.
Set the VR 1.984K Ohm, booted in @ 3,17 Vdimm stable.
Then windows rebooted for some weird reason so I thought I would "fix" the problem by changing VDDR from "auto" to 2.6
ROFL did not help at all!!
Next thing I know I'm reading the mosfet and its spiking upwards 3,78 and then randomly falling and flying up again in a span of 5 seconds.
I was like "OMG NOOO STOP CPU YOU NOT SPOSE TO DO THAT!!"
But now she won't boot so I got an RMA approved to send her remains back :)
EDIT: Yes I'm on a K8V Deluxe K8T800 and I have a VMod on my board and I'm pretty sure my CPU is dead dead dead ;)
PRanganathan, nice job on reading those voltages while it was happening. I think that's the first real proof we've seen all this time of a possible voltage malfunction causing this.
