Testing a 4400+ CCBWE 0543TPMW with a stock LS at the moment:
Works down to -26 (MBM)/Evaporator -51 with no probs.
Cheers, del.
EDIT: Im sure it would work at colder temps but -26/-27 is a low as i can go.....
Isn't that really a Toledo? I thought Manchesters were LDBHE and Toledos CCBWE; mine is Toledo and bugs at -26C hmmm nice consistency if so.Quote:

Well, actually I think it's a Toledo with half of L2 disabled, labled as a Machester E6. :)Quote:

So the famous cabne 0530 apmw opteron doesn't coldbug badly.
I am in the process or contemplating phase change? I have heard and read mixed things about this, and would like to hear of someone that has seen one of these on phase.
FX57 CABNE 0530APMW -69 idle measured on side of IHS ,load -64 -65 on DI and benchable 3803mhz at 271x14 and 253x15
Well, what I wanted to say, bug just didn't find the right words... :p:Quote:

Out of Sandy's and Venices, we know which ones cold bug.. just wish I'd tried a LDBHE now (BH still ruling?
What complicates matters with x2 3800s is that both the E4 (BVBOX) and E6 (CDBOX) are now sold as BVBOX, according to the AMD website. It's pot luck what you get, in other words. Unless it's just a typo.
BH indeed seems to be the most resiliant to the cold.Quote:

You can always let CPUZ tell you what your chip is, either an E6 or an E4.Quote:

No...I think we're talking about two different things - you're talking about the OPN of the cpu and the cpu revision.Quote:

mm.. OK. Now I get what you said. ;)Quote:

Good:toast:Quote:

1. Cpu that can run >270htt with SS @-40C evap. temp.(+/- 25C bios), but only can run up to 230HTT with -90C evap.(+/- 65C bios). This chip usually will run up to 255/260HTT with -75C evap.(dry ice).
2. Cpu thats bug free for all temps...from -40C to -105C and colder evap. temp @ any HTT/Multi.
3. Cpu that only can run 240htt max with SS @-37C and won't even post @-61C:(
All single with ACPI multi....
My 3800+ X2 CCBWE 0548RPMW has no coldbug @ -30 CPU Temp :) (300x10 no problem)
What about the ones that wont post under single stage? I had an opti 148 like that. The lowest HTT I tried was 150 though so I suppose it could fit in cat 3.Quote:

Gotta pick up DI pellets today...
Yup, that's about the only cooling that's capable of doing that. (Unless you somehow have a cascade tuned for a HUGE heatload @ -40ish temps?) With that kind of precision though, you need a really steady hand. Where's Kingpin when you need him :p: He knows how ;)Quote:

Hi Members....;)
CACJE 0601 146 Opteron --->> Buged
KAB2E 0549 FPAW 3700 SD -->> Buged
Cooling with Vapochill LS
