Those on phase no cold bug please post here

[chew*]

Gonna make a data base so I need people on phase to post in this format. Oc's and cpu type are not needed so please just post in this fashion >>>>> Highlighting the 3rd and 4th and what temps you run at.
ONLY 90NM cpu's please. Also cpu temps not evap temps. Please dont post 0 degree core temps most cold bugged cpu's can do that easily. Also as steven pointed out these are benchable cpu's at these temps that we want posted not screenshot cpu's. *EDIT* I started adding cpu's that did bug for comparison purposes.

I've seen idling temps as low as -20C and load temps around -1C (windows).

[Dumo]

Narrow down your criteria...Most 90nm will boot ok with -59C universal evaporator temp. (equal to -25ish cpu core temp in bios)

CABNE -97C evap/-68C bios core temp...

[Fhqwhgads6680]

I tried starting a database a while back, there should be some results in there.
http://www.xtremesystems.org/forums/...=90nm+cold+bug

I hadn't heard of this new information at the time and was trying to collect some data on the coldbug, if the stepping information posted by freecableguy and steven is true this could really help. Good luck!

[chew*]

Hmm I just read that thread......Afires's CABNE bugged at -15. So this isnt necessarily going to tell us how cold you can go but more of a negative temps bootable database. I still think it's luck of the draw how low you can go but this may aid in guaranteeing being able to boot with negative temps.

Unfortuately DUMO the averages of people with phase that does -59 or lower cpu temps is small. I'm trying to prove or disprove this theory as far as negative temps go though as some people cant even boot at -10. Of course there will always most likely some rare cpu's that break the trend.

Both of them don't have cold bug on my single stage @-48C' evaporator.

Ben im going to go out on a limb and say that core temps are roughly -30 to -25C

What's your max HTT -40 core? Me opteron 146 0540 cabye will do around 330HTT with -25 in mbm, max 355HTT -10 mbm. Stock mach II.

DUMO CABNE -68
Ben805 CABNE -25

From the looks of this discrepancy, I have a feeling that you'll have to get a little more specific with the details of the cpu. It's usually safe to assume that cpu's built on better wafers are binned higher. So taking that theory, I'd imagine the difference between Ben's cpu and Dumo's is roughly the difference between a CABNE Opty 146/48 and either one of Dumo's FX57's or an exceptional Opty 150+ cpu. Also, there's a HUGE difference between RUNNING @ a certain temperature vs. taking a screenshot at that temp. Try to narrow down the specifics and your results should group themselves

Yah steve but this isn't the official database I'll leave that to someone else. I'm just trying to test your theory a little and see what we get for negative temp cpu's. give it a couple days so we have a larger look at it.

Ok, np, but I would think it's kinda hard to get a true bearing of what the "functional" temp is of a certain stepping of some people are just posting "windows bootable" temps while others are posting "spi stable" temps

Here's my contribution (off the top of my head....I have quite a few more, but just can't remember all of them without digging through my old pics )

Spi Stable:

CABCE - none
AABHE - none
ADBHE - none
ADBHE - none
CBBLE - none
CBBLE - -90c
LBBLE - couldn't test that low at the time, but ~-27C was fine
ACBWE - ~-35C
CAB2E - didn't even bother...lol

Edit: OOPS I think I posted in the wrong format....all the ones that say none are non-cold bugged. If you want, I can try to find exact core temps, but I have a feeling it may be lower than you're planning to go anyway.....

[Kesnel]

Only one of my 90nm has bugged on my Mach II GT.

These are the lowest I've tested to. At no point have a seen a bug, except on the CAB2E. The chips with the higher temp I just simply couldn't run any cooler on my single stage, it's not that they bug there.

(3700) CABGE: -34c
(146) CABNE: -29c
(144) CAB2E: bugged around -10c
(146) CABYE: -30c

Well i categorized them by theorized revision. Earlier memory controllers have lower alphabetized steppings. Now maybe you can see where i'm going with this.

Mach 2 GT X2 4800 -37C also FX 55 -31 & 57 -31 no cold bug. Will have FX60 tomorrow, will report then.

What's your max HTT -40 core? Me opteron 146 0540 cabye will do around 330HTT with -25 in bios, max 355HTT -10 bios. Stock mach II.

had it at 330htt but the core was around -35 at that time.
