Binning celerons for CPU-Z Global pointage
 

Had an interesting thought. While CBB seems to be around -80c on the commando with 2 of the celerons I bought going to try some wacky perhaps stupid shit but the line between inovation and failure is fairly small so what the hell.

Since we all suck at cpu-z (Globally no offense guys ;) patch excluded) I thought I would try some shit out that might make it a bit easier.

Goal: Bin the 5 celerons chips I have sitting here using the least ln2 as possible.

Current Best way: Get a cheap low mass pot and mapp torch.

Idea: Use some dielectric grease mixed with your ceramic to keep the pot from freezing to the ihs (before hondacity yells at me keep in mind we are binning the chips not going for the world record speed) NO hold down, just the pot weight on the chip. When I BSOD I will remove the pot, boot the chip put the pot back on and win?

Why: Going from -180 to -80 and back takes alot of ln2 alot of torching and alot of time.


Results and pics to come, loading OS on commando as we speak. Thoughts and kind words appreciate, GO! :good:

Used just enough to cover the base and a bit of the lip of the f1, spread it with a ruler :laughing:

Pot was very stable, within 5c of the bios from 20c to -80c before the first pull

Chilled down to -140c, pot was still easy to twist and easy to pull right up didnt have to force it. Pic is me pulling it up and booting to get around the CBB. Worked great, little ice around the socket because I wasnt using any paper towels or the usual black neoprene insert.

And a pic after playing around for an hour and a half with pot around -170 the whole time. Dielectric really kept the frost at bay :thumbsup:

In conclusion. I would use a bit more of the grease next time. After pulling 2 or 3 times temps where poor. -80c in bios with a full pot. Holding the pot down with some pressure for a minute helped by melting a bit of the ice on the edges then freezing back up in place. All and all worked right to plan, let me play with the board around getting used to aux voltages the chip likes. :thumbsup: I will use this method again for sure.

at -80c with plenty more voltage to go. Might be a winner.

The board on the other hand is very quirky, will have to start a new thread for that.

woot i don't put the hold done for 30c benching...ummm os install rather..hahahah

monitor vid in bios ....

about the paste....i don't use paste :D

Sounds like a sound plan of attack Splave, good luck on finding the golden goose ;)

Nice idea. The -80 CBB is a serious PITA.

^ you said it patch :)

UPDATED WITH RESULTS

I like where is thread is headed and that direction FTW! :)

Nice direction there splave, but since you want to bin the chips, you plan to remove the CPU and put a new one mid-session as well? or did you already do it and I missed it? Though mid-session change of chip doesnt sound like a gud idea since there wud be then air-pockets...

Splaves pot acrobatics! I like it! :D

thats the idea, I wanted to see if I could remove the pot at -180s from the board and I could. When I bin them I wont go over -100c or so. The key is keeping the base in contact with something so it doesnt frost over. :thumbsup: Im not worried about air pockets because there will be air pockets for sure. I can always take the pot down to -180s and have the cpu at -100 or so. This is just for binning not all out for a score. :)
