so is it not wise to advise running 2.4V is a little dangerous?Quote:

Speaks for itself.
tony, sure, but beeing cautious when raising volts is like a general thing...
everybody knows that ocing can and will damage your hardware sooner or later depending on how much you oc and overvolt it...
from what ive heard so far i wouldnt say k10 ocing requires extra caution when using high vdimm... it seems we have only 2 people with dead cpus from high vdimm... and we cant be 100% it was really vdimm what killed them.
kte, dont tell me that 900mhz mem clock was with anything higher than 333 timings! :mad:
2.9v vdimm with 444 or 555 clocks and only 900mz clocks would deserve some :cord: :D hehehe
how long did you run 2.9v?
is the mem still alive? :D
is the cpu still alive?
did you notice any degradation in memory performance?
That would be pretty easy for that mem :DQuote:

-30 minsQuote:

-Perfect
-Perfect
-Nope
The difference is that this over-volting of ram beyond what seems safe now, will kill the cpu and not the ram. What warranty will AMD put on the cpu then? That is the question that makes me wonder and err on the side of caution. OF course all can do as they well please since they pay for the pieces. RGone...
PS: because I nearly forgot, you can chalk up another phenom death due voltage and extended strain.
kte, wow, fatbody? impressive!
robert, was it your cpu that died?
could you post some more details?
what cooling, what voltages for how long... what mainboard... any symptoms of the cpu/board acting weird or geting unstable before it died? how exactly did it die or is it just unstable at stock now?
Just some plain el' cheapo Crucial Ballistix Tracer 8500s. :D
I'd have pushed them with this arch to see if I can get 675 4-4-4-4 but I can't even get 1066 to work, let alone any further. :(
To bad 939 cpus is hard to find this theys so i dont want to test if my 24/7 cpu can take low vcore and high vdimm like 4.1v and <-1.1vcore. K8 is not phenom but it still have memcontroler in the core.
Am ok at the minute am using a phenom on a 790FX board with my ballistix set at 2.3v! 4,4,4,12 1000mhz
in germany you can still find lots of 939 cpusQuote:

I noticed I had a non-booting Phenom like some of you were saying, what you would call "dead Phenom", but I didn't return it even after 3 days although I was about to, rather I experimented and repeated it. It was caused by just going past 626MHz on RAM. Voltage didn't matter whatsoever, I've had 5 Phenoms (7-43/7-44/7-45/7-47 etc) now and ran 1.8-2.9VDIMM on them varyingly since around 20th November '07 at low and high VCore and at low and high NB VIDs, no mem. degradation whatsoever nor did those affect it... but speed did. Phenom did 626 4-5-5-15 at 2.2V BIOS/2.18V real fully stable but failed to boot 627 even at up-to 7-8-8-22 2.9V. It did not matter what IMC/CPU volts were fed nor the CPU/RAM temp (up-to 10C idle tested). :yepp:
The same RAM I swapped in a P35/C2Q setup and it ran 2.2V 676MHz 2.3V 5-5-5-5 SPi 32M with ease 4mins later.
Guess how it all happened?
When choosing high mem speeds on 1:2.66 divider, Phenom would get stuck in a reboot cycle even at low volts. No POST, no matter what you did even after 2 days. By checking the various voltages, I found CPU voltage had dropped to sub 1.19V at whatever setting you chose before that, it didn't matter and that caused a failed bootup -- didn't matter which CPU/NB/HT speeds/volts you ran previously. I usually test under cold and as you'll see documented in the 9500/MSI K9A2 Plat. thread, I had to take the CPU subzero (below -15C) and leave it at those temps for 30mins, then bootup with only one DIMM installed and it would always work fine and restart up thereafter. So "dead CPU" perfectly alive again. ;)
If it were anyone else not trying sub-10C, or even me not trying it, it definitely was like a dead CPU and an RMA was needed.
