venice on ice 2850mhz 1.38v -40°C

[saaya]

first of all BIG thanks to s7e9h3n for making this preview possible!
thanks a lot for bringing those chips to XS and letting us freeze and torture them
and of course big thanks to our trusty member chunkylover77 for letting us play with his 3500+!
thx a lot guys!





after last weeks results of a 3800+ venice from s7e9h3n here
pc ice now received the 3500+ venice from to s7e9h3n to play with it using his phase change skills
and it looks like the low temp bug is gone!!!
i will keep adding more results here step by step

EDIT: bad news! opp cant get it to work under his cascade, seems there is still a low temp bug :S

now lets hope E4 changes that, so far i only heard that E4 had changes made in the temp probe , thats why it needs a bios update to work on almost all boards.
i really hope the low temp problems dont have to do with the manufacturing process!

phase change cooled system specs:

AMD 3500+ 2.2ghz dafault vcore 1.4v 90nm Rev E3 Venice core @-40°C
pc ice single stage phase change cooling

SAPPHIRE X850XTPE 688 / 644
OCZ POWERSTREAM 420w






here are the first results at stock speed (11x200):

update:
cpu-z 1.27.2 or the latest CBID couldnt recognize the cpu either, dave will try to use cpu-z 1.27.2 to verify a shot though

update:
the superpi version he used was not sse3 patched, but he will test superpi with and without the sse3 patch to see what the difference is and how much sse3 helps those chips to perform

update:
the bios incompability issues you have all heard about are about the E4 stepping (san diego 1024kb L2 cache 90nm) not the E3 (venice 512kb L2 cache 90nm) so you dont need a bios update for the venice chips that will be released on april 4th

update:
we will add watercooled and aircooled results later

update:
please stop pming pc ice! hes very busy atm pushing this baby even further

update:
the screenshot indicates he is running 2GB of memory, this is a bug!
however, he will test with 4 DS 512mb sticks and post results

update:
bad news, pc ice hurt his back has the water and air results on a raid array he has problems accessing now. he will post the results asap though.
lets all wish dave to get well again soon

update:
more than stock vcore barely seems to do anything to this chip
lets hope that its just because this is an early chip and that future chips will scale better with more vcore. and 2.8ghz with stock vcore on water is not a bad result by any means

update:
pc ice tried it again under his cascade and the chip didnt boot at -90°C either, so theres def a low temp bug. :/
