HOW TO ENABLE TURBO BOOST I7 4770K FULL

HOW TO ENABLE TURBO BOOST I7 4770K FULL

I reset everything to the defaults and then set all my preferences back again, and it worked! The CPU sat at 35/3.5GHz and went up to 37/3.7GHz, but it didn't reach the full 39/3.9GHz multiplier. Thanks for the suggestion, and sorry for taking so long to try it out, rebooting is a bit of a hassle for me! Maybe the bus speed/host clock needs to be increased? The Ark for the CPU doesn't seem to list a bus speed so I'm not sure whether 100MHz is correct. I'm a bit reluctant to reset the settings to defaults since I have customised a lot of things, like making only my external SATA ports hotplug, but do you think this will work? It is a bit weird all the voltages and multipliers were originally set to zero. It's faster than before, but still only maxes out at about 3.8GHz. I tried upping it past 39 up to 45 to see if I could reach at least 3.9GHz but it doesn't seem to make any difference. I still wasn't able to adjust the non-turbo ratio (which should be 35 for the 3.5GHz base speed) however booting back into Linux this does at least seem to allow me to get close to 3.9GHz in boost mode. I don't know why this doesn't come up when you click on it, that would seem most logical to me, but maybe it's a secret setting and you can only get to it with keyboard navigation.Īnyway, adjusting that changed the settings on the right for some reason:

I worked out that if I clicked on the 'x 0' under the 'Cores' heading, although I couldn't change it, if I pressed the arrow buttons a little bit a slider would suddenly appear that let me adjust the value. I wasn't able to adjust any of the turbo boost options either. It seems to be fixed at 30 for non turbo boost. I have found some time to reboot and have a look in the BIOS and it does indeed seem that the multipliers have been lowered - although I can't turn them up again. Sorry for the ugly post, looks like doesn't show up in a fixed-width font after you post) Does anyone know why the processor is running much slower than its rated speed? I'm running this in an Intel DH87MC desktop motherboard, and temperatures rarely go over 60 degrees even under full load so I don't think it's a thermal problem. $ cat /sys/bus/cpu/devices/cpu0/cpufreq/cpuinfo_max_freq Model name : Intel(R) Core(TM) i7-4770K CPU 3.50GHz Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 32x/32x/31x/30x Max Frequency without considering Turbo 3091.73 MHz (99.73 x ) TURBO ENABLED on 4 Cores, Hyper Threading ON Why would this be, when it is marketed as a 3.5GHz processor with the ability to Turbo Boost up to 3.9GHz? The Linux cpufreq information tells me that the processor is reporting its maximum speed as 3.2GHz. compiling in parallel) it stays at 2.992GHz, and when it is idle it creeps up just above 3.1GHz, but never goes any higher. I'm running Linux, and I have noticed that my i7-4770K CPU never goes above 3.2GHz.
