Lenovo Y510p with i7 4700Mq processor PROBLEM!

[TLied]

Hello,

i have problem with my i7 4700MQ.I bought half year ago Lenovo Y510p with this processor and when i look on task manager or on CPU-Z, it says that the processor has 2 cores and 4 threads. It would be a software problem or HW? And the second problem is, that Turbo Boost is not working.Noteboock

Can you help me?

Notebook spec:

Lenovo Y510pIntel i7 4700MQ16 GB DDR3 1600MHz RAMMainboard Lenovo 20217BIOS Lenovo 74CN35WW

Windows 8 64bit

I attach images of CPU-Z with running CPU stress test.

Thanks

I am sorry to hear that have had issues with processor model i7 4700MQ.

I have checked the picture attached and indeed shows 2 cores and 4 threads.

At this stage, please check for any BIOS settings that may have disabled CPU cores or try updating BIOS of the computer here:

By updating computer BIOS you may get Turbo boost running on the computer. If you need further assistance I recommend engaging through Lenovo's Technical support at:

Thanks for your reply.

Meanwhile I solve this problem. I update Windows from 8 to 8.1 and all 4 cores and also Turbo boost is working.
