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.

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/showthread.php?t=85406&highlight=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! :toast:

[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.

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 :2cents:

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 :p: )

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.

very much so agreed, ijt would be interesting to know why an opty cabne cant go nearly as cold as an FX cabne.

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:

The s939 "Opties" aren't true Opterons like the s940 server/workstation cpu's from AMD. Instead, these s939 versions are a means for AMD to rid themselves of any "extra" San Diego cores they have left. 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)....

[Revv23]

fair enough, but why bother with dual core opties if you are just clearing out stock?

[s7e9h3n]

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......

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.

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 ;)

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.

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?)

CABGE 0536 no coldbug down to -30 idle. Clocks past 300HTT fine at this temp. :D took me long enough to find one! (cheers njkid!)

[kiwi]

Opteron 146 CABYE, idle -27C, load -5C, bugged at idle temps and htt >325

[ThorLite]

Opteron 146 CABNE 0544 EPMW, idle -28C, load -4C, bugged at idle temps and htt >305.......

[kiwi]

This su*, need unlocked multi :D

From 3 chips under phase/dice, 2 were bugged but this happens only above some HTT :slapass:

[girth_maul]

Anyone know how an 146 CABYE 0540 FPAW will fair? I've just ordered myself and chilly1, but had it overcharged for higher temps and hopefully no coldbug.

[stone_cold_Jimi]

My chip is no longer coldbugging over 255 HTT/-26C, it's more like 290 now. In fact I'm typing this with it at -30C @ 270x10. Why? Different RAM settings. It's not completely gone by any means but it has receded to a point that's more managable. Setting a lot of stuff to auto really helped. ;)

[kiwi]

I thought only Drive/data strength might help. What else? I have tried many settings, also auto.

[stone_cold_Jimi]

I set drive/data strength 3/auto. Trc was the other biggie - manual at 7, auto at 15. 7 works for some ppl with HZ but not me.

[rekin]

fx 60 -->> CCB2E 0536 WPMW very cold bug :(

[Kendragon]

I have to agree with rekin.....FX-60 CCB2E 0536 SPMW, worked at 3.4 for about 20 minutes, rebooted, will not boot at all now. -27, then NO BOOT at all even after overnight wait.

Also X2 4800+ CCB2E 0536 WPMW also cold bugged. -25 bios(250HTT) Ok @ stock to 238HTT

We need to stay away from CCB2E's of any kind it seems like. Not for aPhase although descent on water, both chips ran 3 gigs on water

[Dumo]

Welcome to XS Rekin and Kendragon:toast:

XXX2E really sensitive with evap. temp around -37C.

[Eldonko]

FX-57 CABCE 0530 BPMW no cold bug under dice, -51 core. Tested HTT to 350 :woot:

[rekin]

thank's Dumo :)

after testing my FX60 cold bug at -17° ; I put a copper plate for avoids cold bug enter the evaporator and the cpu.

resust: full stable and booting good at 3.3ghz


sorry for my bad english because france power :D

[Kendragon]

Could you elighten us on the copper plate? I do have an extra A64 heatspreader(Damage 3500+) i may be able to dremel the edges for that purpose. Cause I'm sure even with a plpate 3.3+ is capable on mine, or I am gonna RMA it. Was shipped 2/23/06 ZZF has the 15day so friday next week can still RMA.
And thanks for the welcome Dumo, you'll see me sometimes on Bleedinedge.

CABYE 0528GPMW FX57

on 2 stage ethylane cascade -105 idle -98 full load
core @ -63*C can boot up to 245Htt
once on multiprocessor in windows @ 208 from smartguardian (-48*C) can do more than 280Htt, havent tested more

on single stage -25*C more than 350htt is possible as tested

[Nephilim]

CCBWE 0546 MPMW = Opty 165 dual core

POSTs @ -50 (evap temp) and boots and benches @ -27C cannot really test below that.

HTT tested up to 350 or so fine. has x11 multiplier unlocked. :stick:

[Stelios]

No cold bug with : Opteron 175 (310X11) @-45 (smartguardian) , or -52 evap .
CCBWE 0530TPMW

[andL64]

An Old 4000+ KABYE dunno week and so on was pretty nice @ kaskade -80C evap -47C core no problems.

146 opteron:
CACJE 0601 GPAW -10Core temp buggy, doenst start in win
max.HTT not tested, yet
3700+ san diego:
KAB3E 0548 BPAW -15C core temp buggy, doesnt start in win
max.HTT, 325x11 no problem

MPS Multi cpu helped also more Volts to get to -10 or higher.

180 dc - ccbwe 0530tpmw - not cold bug on my SS

athlon 4200x2 cdbhe 0522tpmw not cold bug on my SS / d.ice

[SoddemFX]

Opteron 148 0543 CABYE FPMW

My CPU reports very very wrong temperatures, swinging from -30C to +8C within a few seconds. The hardware monitor on my DFI NF3 Ultra-D is very wrong.

http://www.pclincs.co.uk/Forums/attachment.php?s=&postid=86822

The evaporator face is at -40C and the back of the motherboard is at -20C so i would assume a core temperature in the -30C region as im running low voltage.

I have not encountered any "cold bug" with this CPU.

[cdelong]

that's nice cause I have a modded LS on the way and have the same stepping CABYE. It already runs 3.0Ghz on air!!

WOW... :slobber:
So, either your autocascade was colder than ever or you were using something different. :D

[lemonlime]

Opteron 148 CABYE 0543FPMW

Slight cold bug on mine, have trouble passing 300MHz HTT. It got really bad when I removed the IHS and I got lots of hard locking at idle temps around -30ish, so I have since reattached it. Runs no problem at 11x291 24/7 with no bug.

[s7e9h3n]

It's all cpu ;)

[chew*]

OK guys its time consuming but i've updated up to page 4. Note's of interest as of late are some interestng X2 chips floating around with the stepping LDBFE. At this point in time there is no sign of coldbug however none that i know of have been tested beyond -35 cpu temps..........A volunteer to send one to Stephen or I for xtreme cold testing would be appreciated. Would rather it go to stephen as he can pull colder then I can with more consistent temps.

*edit* Dumo would also be a good candidate for max cold to test this cpu..........

[Dumo]

I can test it:)
Opps, no I can't....no mobo/mem left.

I can arrange for a temp mobo and ram for you dumo......... sapphire RX480 and 2x256 bh-5 suit your fancy?

I'd be happy to test that for you - I'll even let you choose what type of memory you'd like it tested with :D BH5, UTTBH5, TCCD, AENON, or basically any other type I'll have access to ;)

CABCE - CBBCE would make it a 512K L2 FX55 :p:

Gah, soz... Spent last 4 hours mounting evap so it made decent contact and am now nackered :stick:

Atleast I get better temps than I did before, though :rolleyes:

Thanks for pointing it out, I probs wouldn't have noticed it otherwise...

I may have seen the demon this morning - I booted at 345x9 same as yesterday and left it with only Firefox running while I went and put the kettle on. System froze while idling. Ran over 3 hours of dual SP2004 while multitasking on the desktop to check, no instability whatsoever. That's a temperature feature or I'll eat my hat.

Now 3:20 into 2 Rosetta jobs, average -8C to -10C. Perhaps I'll run 310x10 later and see if it locks up tomorrow.

Small update on my stepping CABCE 0522 XPMW -84 evap -50 is core I think

Hi

Is the Opteron 165 CCB1E 0605XPMW Buged?

THX ;)

[Vapor]

Add more data to the thread: my CCBWE 0517 MPMW 4400+ is fine for core temps down to at least -28C.

[Kesnel]

More than likely - B1 mem controllers are notorious for bugging.

[Leverpospade]

X2 3800+ LDBHE 0601 UPMW, it can easily handle -20 C* haven't got the equipment to go colder. Gonne try some DICE soon and see how it does.

[Emperor]

urgent!

is 170 0550vpmw ccb1e bugged??

[Vapor]

Yes, very.

[K404]

yes. B1= bug

[Emperor]

is it possible to overcome/avoid this ?
because waht i heard is that cold bugs happen at certain temps?

[TheMeatFrog]

Opteron 148 CABYE 0543FPMW cold bugs at -20 idle at anything over 300HTT

[Turrican]

My San Diego 3700+ KACAE 0552 FPDW is also very bugged.

I need ~+20 to get a HTT of 300 . (Ricky Tweak+2nd Heatspreder between cpu and evap. :D)

at the moment 295x11 is rockstable.

I have Opteron 165 CCBWE 0547TPMW has it ColdBug? I've read that its good stepping for phase cooling, but maybe someone has the same stepping?

[K404]

Anyone got info to add on the Rev.F CPUs and the new steppings?

:) Thanks

I know these are 754, but..

There seems to be missing data from list started by Chew*. I have a KAB3E and it's not on the list. I have just bought a new phase unit and I wanted to know if or how badly:( cold bugged it is before I start. Can you help?

Cheers:)

[ozzimark]

i don't have personal experience with one, but what i have seen of the KAB3E's, it will be bugged pretty bad. probably -20c to +10c as an approximate range, depending on how high you want to go with the HTT :doh:

Thanks for letting me know I kinda thought it would. Looks like another upgrade then :D From the data I'm still not sure what stepping I should be going for I should probably change to Core2 but I love my DFI expert too much. :p: any advice?

Cheers

[likewhoa]

anyone know if this stepping has the coldbug caa2c from an fx55.

edit: seems the clawhammers are immune to coldbugs :)
