CPU-Z validations keep on coming as overclockers test upcoming hardware to the limits. Earlier, we reported about a CPU-Z validation revealing AMD FX 8570 eight core Vishera processor and Radeon HD 8970 GPU. Now, another user validated an Intel Haswell Core i7-4770K processor overclocked to 7.01 GHz at 2.56v.
Its of no surprise that Haswell processors will have better overclocking potential than Ivy Bridge processors due to variable DMICLK/BCLK [base clock] coarse ratios. Sandy Bridge and Ivy Bridge unlocked ‘K’ series processors are overclocked using the processor multiplier which helped increased the overall CPU clock frequency. Back in the days of the 1st generation Core i series processors, users used the BCLK ratio to overclock the processors and now Intel is bringing the trend back with the new Haswell micro processors.
According to the validation, an unknown overclocker overclocked Core i7-4770K CPU to 7.01 GHz at a whopping 2.56v voltage. Either the voltage is not being displayed correctly or Haswell processors are designed to reach the extreme limits. ASUS Maximus VI Extreme motherboard was used for such an extreme overclock on Core i7-4770K, if you still haven’t seen this amazing ROG series motherboard then you can check our earlier post for a full coverage. ROG series motherboards are designed for extreme overclocks and are known for their stability. Many renowned overclockers use ASUS motherboards for LN2 overclocking and achieved many world records.
A recent update from Overclock.net reveals that a Core i5-4670K is also overclocked to 6.2 GHz at a reasonable voltage of 1.2v. There is a lot difference of voltage between the two overclocks, obviously Core i7-4770K comes with four cores and eight threads while Core i5-4670K comes with four cores and four threads and both are overclocked to different speeds, but that still does not justifies the extreme voltage for 7.01 GHz. Never the less, both are some impressive results for Haswell processors and they just might live up to the expectations.
Haswell processors are due to launch on June 3rd, 2013 and after seeing these amazing overclocks one just can’t wait to get their hands on them.
