Hey all,
After the SF3D OC Gathering Vol.X binning event, I quickly tested the 20 Core i 7 3770K chips I brought over for IMC overclocking capability on air cooling.
Test system:
- Core i7 3770K (obviously)
- Simple air cooler with 1 fan
- GIGABYTE Z77X-UP5 TH
- GSKILL TridentX DDR3-2666C11
There are four states:
- "ok" means the CPU can boot up with that memory frequency
- "66" means the CPU cannot boot up with that memory frequency
- "51" means the memory was not capable of that frequency (like "55" on M5G)
- "/" means untested setting
Of the 20 tested CPUs ...
... 20 passed DDR3-2400 test
... 19 passed DDR3-2600 test
... 18 passed DDR3-2666 test
... 13 passed DDR3-2800 test
... 2 passed DDR3-2933 test
... 0 passed DDR3-3000 test
I've verified the testing on the M5G, the results were of course the same. I also tested the 2933 CPUs with memory under cold and then passing DDR3-2933 was no problem anymore, which indicates that "51" was related to the memory rather than the CPU capability.
The chart:
