Intel Core i7-5775C Broadwell reaches 5 GHz OC on Air

The first Broadwell based Intel Core i7-5775C has been spotted and overclocked. The Core i5-5675C and the Core i7-5775C should be out in stores real soon. Overclockers should be happy as the 14nm Broadwell part seems to do well.

These 65W products have reached some end-users and in Asia the overclock results aren't bad at all. A Core i7-5775C on an ASRock Z97 OC Formula reached 5.00 GHz clock speeds on air-cooling, that is at a core voltage of 1.419V though. The PC wasn't stable enough for benchmarking but did boot into Windows 7 and finished a CPU-Z screenshot.

The Core i7-5775C has a default core clock of 3.3 GHz and 3.7 GHz turbo frequency. The chip is a quad core model with hyper threading enabled and features 6 MB of L3 cache. Overclocked at a 4.8 GHz the system was stable and able to finish a 32M wPrime run in 4.399 seconds. Have a peek at some of the screenshots below, courtesy of Hong Kong-based HKEPC.

Wait I thought K were the overclocking series, so is C replacing that now?

Man if it can reach 5ghz on air makes me wonder what the i7 chip can do with liquid cooling if it can reach 5ghz on liquid with a lower voltage or it can reach a tad over 5ghz like 5.1-5.2ghz.

Exactly what Extreme said, some very lucky chips on Haswell arch. may reach 5G indeed however with extreme voltage and not for every day use.
Good thing seems the 14nm tech that will decrease temps at least.

screenshot OC with 18*C...

Look again...18.8 C is on booting @ default speed. Mine (and I guess everyone's) starts at same temp as ambient,some seconds after will increase no matter what.

No temprature screen for 4.8 or 5.0 G on load @1.4v...

BLEH!
