AMD Survey & Cold Fixes

[epion2985]

The information seems to be all over the place with cold bugs at every temperature. Fixes seem to also be plentiful and very different. I thought it would be nice to sum everything up and put all the data next to each other for evaluation.

Post:

1) What AMD chip you have
2) What temperature does your AMD chip get the cold bug
3) Any fixes that have ever worked for you

Will be nice to see what chips kick the bucket at what temperatures on the average as well the the extremes on both ends and the overall picture.

Heres venice 3500 0528 E6 with DFI Ultra-D...no cold bug up to -95C/-67C cpu core..

On the other side..FX57 0516 with SLI-DR cold bugged @-90C evap. temp...low htt..NO way around it, tried every possible combo in bios :( . ACPI multiprocessor help though...

And FX55 Claw with RDX200..No problem at all even @-99C evap. temp..

2 Opteron 148 chips, 1 CABNE 0528 and 1 CABYE 0536 both with HTT cold bug on Dry Ice =( Damn cold bug!
Dont know the exact temp, but might be arround -20 since one works on the prommy and the other can get more Mhzs on load than on IDLE LOLOL

How about a room temperature bug?
Wait a minute--that's probably my SLI-DR. hehe

I have been hearing in the phase change section that as long as you boot around 0C you are good, the later drop in temperatures will not bother the chip. Probbably because at the very least you have the idle prossess running so its not just sitting there like it is at boot up. I guess you can say amd's have problems getting of the start line when it cold but once they do its a sooth ride.

Anyone have any accounts of this?

Anyone have any accounts of this?Most 90nm chip can run with -65/70C @ htt200, but some wont pass windows.

AMD 90nm cpu that can run windows stable with Htt >230 @ -65C cpu core temp. is a rarity :)

Imo, most chip up to 0530 prod. date have more tolerancy to extreme cold than 0531 and newer...

[epion2985]

Embarrassing question but whats "Htt" ?

Do you think the cold bug will improve or get worse in the future?

How are -40c to -50c tolarated? Stable by majority?

HTT is the base clock speed, roughly equivilent to fsb for athlonXPs and intels

opteron 146 CABNE 0530 APMW
cold bugs around -15c bios in windows and with -28C or lower bios (-28 is the highest ive ever seen) I can't boot over 3.1ghz. I boot 3.1ghz and 1.9v+ and run SP2004 to heat the chip up if needed. I run ricky tweak as well.

I am making a DD right now and will use it on the dual core FX's on the M2 socket or whatever they will be called, 5000+ dual cores maybe?

wondering how low will we be able to take them.
