hmm new aida. lol 2133 C7 at p67 read alredy 31.6k. up from previous 20++k.. personally this read is kindda wrong so need to check with sandra

and latency now higher at 44.3k.

But more importantly, we've replaced the outdated set of memory benchmarks with brand new ones.  The new bandwidth (read, write copy) benchmarks now use multiple threads to squeeze out every last bit of performance from the caches and the memory modules.  On modern multi-core processors, using the old single-threaded benchmarks you couldn't see the actual memory bandwidth, but only the memory bandwidth available for single-threaded applications.  With the new benchmarks you will however get considerably higher scores, much closer to the theoretical memory bandwidth available.  It is especially true for 3-channel and 4-channel memory configurations, such as Intel X58 and X79 based high-end desktop systems; and also for NUMA-enabled multi-socket systems, such as 2- and 4-way AMD Opteron and Intel Xeon based servers and workstations.  For example:

Core i7-3960X with X79 chipset and 4-channel DDR3-1600:

- AIDA64 v2.85 Memory Read: 16825 MB/s  [ old ]
- AIDA64 v3.00 Memory Read: 45640 MB/s  [ new ]

We've also implemented multi-threaded cache benchmarks, that now include support for the latest AVX and AVX2 instruction set extensions.  Thanks to using all CPU cores for the cache benchmarks, you will get dramatically different cache bandwidth scores than with the old benchmarks.  For example:

Core i7-3960X with X79 chipset and 4-channel DDR3-1600:

- AIDA64 v2.85 L1 Cache Read: 121.8 GB/s  [ old ]
- AIDA64 v3.00 L1 Cache Read: 674.7 GB/s  [ new ]

Can keep using this VID up to 4.1GHz, which is supposed to perform equal to a 3770K @ 4.5GHz.

During Computex, Jake Crimmins, Technical Marketing Specialist for DRAM Corsair, demonstrated the fastest air-cooled production memory modules to date, the Vengeance Pro Series 8GB (2x4GB) 3200MHz memory with CAS latency 11 and timings of 11-14-14-36. The extremely fast memory kits reaffirm Corsair's dedication to providing the highest performance memory for enthusiasts and overclockers. Availability will be announced at a later date.

CPU-Z 1.64.0 works fine

@owikh any chance u delidding your 4770k? want to see how's the temp when using coollaboratory liquid pro/ultra! 

5.0 max temp is?

MVIE flashed to BIOS 0006, now 5.0 is bootable and bencable at 2 cores. Max temp 72C although the vCore is considered high. For record, 3770K @ 5.0 can easily hit 105C and throttled.
4 cores might need more juice.

It is not a good chip to delid.
I will look for a golden chip then only decide whether to go with the same way as Ivy.

Sorry...I am very noob and no understand..
U say 4.8 max temp is 98 degree but why 5.0 max temp is 72 degree. That why I no sure and ask u again?

5.0 is running on 2 cores 2 threads only
4.8 is 4 cores 8 threads

both clocks are not for 24/7 but more to benching purpose.

Thanks for explain
How ur golden 3770k, still selling?
I wish to ask :different type of  mobo affect how high a proc go?
Example : my bad 3770k need 1.305 to 4.5ghz in p8z68-v, if I change to Maximus mobo， any different to result? More low voltage or higher oc ?

Sorry for asking ivy here

Worth or no upgrade from 3770k to 4770k ? I knew can google the answer but I wish to hear ur own reason tqvm

i think its the same result you will get.

the frequency and voltage will be affect by individual chip performance.

like my asrock etreme 6 + 3770k can go to 4.6ghz @ 1.28V without blue screen for weeks.

Grab the ASRock OC Formula Z77 and I can guarantee you will get at least 0.06v lower than any ROG Z77.
No idea on the V to ROG though.
Haswell is faster, has more features, cooler and lower power consumption etc.
Worth or not it's up for you to decide.

If same ,  rm1xxx mobo  for  ?
