Those on phase no cold bug please post here

[cdelong]

good info

[del_fuego]

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.....

Manchester 3800+ CCBWE -----> -26º

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.

CCBWE = Toledo

EDIT: I think people are starting to catch on now

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

Well, it doesn't show a bug, it just shows that is unbugged at -26º. haven't been able to try lower temps yet.

All 2x512k L2 Cache X2's will identify as "Manchester", but what core is actually under the IHS can be figured out by the stepping info. You're right - it is a Toledo with 1/2 cache disabled - so technically, it's not a TRUE Manchester

148 cabye 0528 gpmw -> -30° -> 329.9x11 (3629mhz)

[fullup3]

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.

Well, what I wanted to say, bug just didn't find the right words...

I see you're still having problems..lol...

After something I read, I think of Toledos (CBBWE) as 2x San Diego cores and Manchesters (LDBHE) as 2x Venice cores. The reason I point this up is that, in keeping with the thread title, I haven't seen any cold-bugged LDBHEs mentioned so far. I think. 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.

RE: the BV vs. CD issue - Don't let the OPN (the first line) confuse you. Basically, if you ignore what's written on that line and just look to the first five letters of the second line, your findings will be the same.....

You can always let CPUZ tell you what your chip is, either an E6 or an E4.
But Steve, are you saying that there are some BV that are E6? (and some CD that are E4?)

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

I'm talking about the stepping info on the cpu and the memory controller revision....

mm.. OK. Now I get what you said.

A64 FX57 - CABNE 0530 APMW (-28°C)idle , (-20) load : No signs of coldbug yet but we'll try LN2 testing and try to control the temperatures and give the Ln2 really slowly

[Dumo]

EDIT: I think people are starting to catch on now

Good

Basically theres 3 different A64 90nm cpus....single or dual cores

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....

[DesertShooter]

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.

I guess there needs to be a category for the cpu's that bug @ or above 0C.....

It doesnt need hsf
Btw, what cooling that can be set @-36 idle and -33C load? LN2 with timed pouring?

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 He knows how

[tarrcm]

Opti 148 CABYE 0543 FPMW
phase -30C idle/-6C load = no bug
ice not tested yet

FX57 CABNE 0530 APMW
phase -36C idle/-14C load = no bug
ice -50C idle/-24C load = BUG

Did some more dice last night & kept better track of when the cold bug kicked in (idle -50C/load -28C). It first happened @ 3355MHz and in a while was OK till it kicked in again at 3404 MHz.
Temps remained the same, is it normal for that to happen?
