If PcCI2iminal's chip is synonymous of the coming C3 retail products, they won't need a higher maximum overclock to shine. The improvements he has shown will give the typical overclocker better results because C3's will require less voltage and consequently less cooling to achieve a good stable 4GHz+ system. Think of it as the voltage/temperature curve being pushed further towards the cliff at the end. The cliff of maximum benching clock under LN2 and LHe may be the same, but there's more headroom back in the smooth part of the slope where most users will operate: above average air cooling and intermediate water cooling.

translation:

performance per watt is better on C3 by a noticeable margin. (good news to people who pay their own electric bill and like power friendly parts)

Nice C3 chip, max clock for my 550 C2 on TRUE BLACK with 4 core = 4410 mhz, superpi 1m @ 4231mhz/NB 3003Mhz :

At least that one with 'top mounted fan' is able to compete with a Scythe Big Shuriken - a little bit better.

If you'll use your solder iron and bypass the temperature dependend resistor it'll perform even better but will be very noisy ;)

That's good to hear.
too bad I just bought a 955...

very nice m8
Ive tried a bit on air and 4cores at 4600Mhz is possible :D
True plus 120MM @ 102CFM

I was able to get up to 4.3GHz , but couldn't get it 100% stable at 3.8GHz on stock air :(

For whatever reason, almost no unlocked processors will boot at HT link speeds higher then 1.6Gig on Biostar
but new bios brings some changes :D

the HT link issue is fixed :D

Nice stuff junior, keep it up. :up:

Finally biostar fixes that HT speed issue on unlocked chips. Nice to know they have the enthusiast in mind as a priority.

whau good, what show it awith 1.5V? Is 4100MHz+ Cinebench possible? With 1.42V its great!

OMG! only on air can hit 4,5Ghz, how about if the procesor feat with TRUE black ck..ck..ck... awsome !!

Great results!! The 965BE C3 125watt should have better results considering it is binned for all 4 cores at 3.4ghz.
