only showing two cores on I7 7700k

I bought mine just before prices went up..

Maybe trying flashing the BIOS again. Did the the system boot with Kaby? I mean before you updated the BIOS.

Darkwolf441 · 20 Sep 2017 at 18:06

I updated the bios when the I5 was in few weeks back no problems

This happened to me when I installed a phenomenal 1050t in a old dual core system without re installing windows. Under number of cores menu there are some tick boxes uncheck number of processors and reboot. Then re access the menus you'll be able to select 8 if it worked.

Wheres this? In system config?

Disco_P · 20 Sep 2017 at 18:17

I'd try it once more and if it still doesn't work then send it back.

Perhaps this is a sign to wait for coffee lake for the performance/price drops

Darkwolf441 · 20 Sep 2017 at 18:18

Coffee lake wont work in my mobo. and the 7700 have gone up in price by nearly £50

Can you run Cinebench multi-threaded please and report back with the scores?

Msconfig. Then under boot advanced options. Above number of cores is a tick box uncheck it and reboot then back to msconfig boot and tick the box and see if you can select the right amount of cores. My one only said 2 cores before however speccy said 6 core. Did that for no real reason and it let me select six cores. After that it was massively quicker

So Windows being Windows again. Thought as much.

Darkwolf441 · 20 Sep 2017 at 20:17

jigger · 20 Sep 2017 at 21:07

Whatever keeps Windows happiest.

As said by the guy now select 8 and it's all swell

Personally I found unticking it to be best and it will go up to the maximum.

Correct me if I'm wrong, but Coretemp will only show the physical cores and not logical cores? Use Task Manager and see how many logical cores it can see.

I'm surprised it took so many posts for someone to suggest checking msconfig

tbqh what happens is msconfig says 4 and wont let you go up to 8 i think he checked that early on its just for some reason unticking and rebooting seems to reset the counter.
