OMG

Very insane.....

Nice rev C3 chip, want to take that...

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 :

No highleakge C3 chip to play with for overclockers?

**ridney** · 10-08-2009, 12:59 AM

criminal, can you give us some air results and temps for your c3 chips and post it on the amd section please??? hehe

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...

**JoNo216** · 10-08-2009, 04:52 AM

keep up the great work!

very nice m8
Ive tried a bit on air and 4cores at 4600Mhz is possible

True plus 120MM @ 102CFM

TWKR II maybe hehehe

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

**PcCI2iminal** · 10-08-2009, 08:06 AM

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

the HT link issue is fixed

**EnJoY** · 10-08-2009, 08:57 AM

Nice stuff junior, keep it up.

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

**FlanK3r** · 10-08-2009, 09:14 AM

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

**YuDi IzzY** · 10-08-2009, 01:34 PM

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

**Utroz** · 10-08-2009, 04:17 PM

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

please upload the new bios that fixed 1.6Gig ht-link

+1 looking forward to it

**YuDi IzzY** · 10-09-2009, 02:25 AM

i'm waiting this one available to my country

**ZoLKoRn** · 10-09-2009, 06:36 AM

Huh... that sick Chip ! nice work Mojo-Family

**zowix** · 10-10-2009, 08:55 AM

Gief the release date for the C3.
Gotta have one with it :O

**Smartidiot89** · 10-10-2009, 09:09 AM

I Demand Moar Results!

EDIT: XS editted my caps lock

no m8

i tried a bit more vcore but no go

i just need to test a bit more before make public ,just wait a little more

thx Zolk

**PcCI2iminal** · 10-10-2009, 05:39 PM

Phenom 2 X2 555 #2 plus 2lts of ln2

first sub 11's with DDR2

6525MHz 2cores(Win XP SP3)

6579MHz 2cores(Win7 Ultimate 64)

guys ,boot at 6400MHz is possible

and i went into windowns at 6200MHz
and sorry ,no screenie for any 3d as we were running out of ln2

**EnJoY** · 10-10-2009, 05:47 PM

Nearly 6.6GHz on a 64bit OS? Wow...C3 is for real!

Daym.... I really want one of these! Seems like they are getting really close.

Where you at 64NOMIS (Simon)....
I'm really hoping this was our prize for helping you with the OC trials.

Send me one, and I'll make your Proud with my Ghetto WC OC results...
