A64 4400 CCBWE 0522 TPMW idles fine in windows at -27.
Opteron 144 CABGE 0536 VPMW and CABYE 0536 GPMW over 345HTT instant freeze in windows when temp goes lower -27 and if bios temp is lower -25 over 345 cant load windows both of them same behaviour.Below 335 HTT no cold bug when sitting idle in windows.........
another under my mach2
CBBID 0501 DPMW runs aboot -20 idle -10ish clocked to 2.9
Opteron 175:
CCBWE 0550UPMW
Coldbug free atleast up to -35c (can´t try any colder)
Opteron 148:
CAB2E 0547GPMW
Coldbugged even at -10c.
I find that very hard to believe ;)Quote:

BUMP for more steppings............
CAB2E Opto 144 0540 FPMW
Bugged at -25 idle and still bugged at -5 loaded.
Had postive temps through deliberate bad contact to try and clear it but nothing great. Couldnt pass 255x9 at any temp.
No subzero her, but my CAB2E 0546GPAW coldbugged at +14°C ... :slapass:
looks like BL is the best one...
@Funkflix: OW!
@Revv....I got to that conclusion as well....the search has started :) I had a Venice BL 3500+ that only did 2.6 under air...600+Mhz under phase would be a nice boost :)
Opti 150 CABGE 0534 SPMW no cold bug to -32C
San Diego 3700+ CABGE 0515 no cold bug to -32C
Both fine under single stage even at stock volts and no heat tweeks but cant function under dice.
Interesting. BY seems to be doing pretty well under phase. I need fo find someone who has phase around my house.
Hey charlie, mind if I come over to simi sometime?
CCBWE 0536 MPMW Opteron 165 Cold bug @ 355HT -5° cpu.
Updated, Keep them coming thx.
It seems for the most part, that the opties tend to have the cold-bug kick in @ higher temps than the regular a64's/Fx's of the same memory controller rev. That may be of something to note ;)
agreed steven..better silicon i'm guessing...which you already saidQuote:

It seems to me a fast die that would end up in an FX doenst always mean that it will take the cold, just look at all these FX stepping opterons that cant touch the temps that the majority of FX's are able to take. Perhas there is more to amd binning hten we once thought.
Ive said this before, but here it is once again:Quote:

The fab process is moving to dual cores only and the new E6 "single core" Diegos reflect this change (dual core with one core disabled)....
fair enough, but why bother with dual core opties if you are just clearing out stock?
Same reason why they don't just sell these Opties as regular Diegos ;) - people will buy it just because it's an Opteron. Also, it increases their market share in single-cpu workstations since in the past, the 1xx series of s940 Opterons didn't do as well as hoped......Quote:

x2 3600 E6 CCBWE 0546UPMWcold bugs below -26C and above 255 HTT.
By reducing the LS fans to 30%, I can mostly keep the core at a degree or two above the bug at boot time - booted 277 HTT this way. Needs a load once booted, else it locks up and/or BSODs if it gets down to -26C above 255.
Dumo was right - evap needs to be above -37C for this to work.
Opti 165 CCBWE 0550 UPMW no cold bug to -32C. Dice testing next week.
4000+
CABHE 0505fpmw
Cooled by mach2 to -25 cpu temp, no bug so far :)
Winnie 3500+ CBBID ----------> -41º
Sandy 3700+ CABGE -----------> -27º
Manchester 3800+ CCBWE -----> -26º
Only tried on dice the winnie. Will post results on the sandy + dice within a coupple of weeks.
