Hi,
Yesterday I started to play with my new computer and I did a bit of oc. I haven't done this since long time so I have some interrogations
My setup :
- Intel Core i5 6600k
- ASUS Z170 Pro Gaming
- 2x8Gb Corsair LPX 3200Mhz
- Custom loop WC (only my CPU)
I was first concentrate on the CPU oc, so I have set my memory to 2133Mhz, BCLK to 100, FCLK to 800Mhz. I have set LLC to level 5, vcore to 1.35v and I just played with the multiplier.
I have been able to boot Windows and run some superPi up to 5Ghz, I wasn't expecting that much with so few tuning ! But, to try to find a stable OC, I lowered to 4.7Ghz and I am now trying to get it stable at the minimal vCore.
Here comes my questions :
- If I try to lower the vCore, the core #0 of my CPU is always failing after 1-2 min under Prime95 while other cores can run for a hour (I then stopped the test), do my CPU has a weakness or is it normal that one core fail first ?
- Does Prime95 FFT Test is really representative of reality ? Cause at 1.35v the Blend test get my CPU to around 65°C, that's a good temperature I presume for the life of the CPU. But FFT hammer it so much harder, I get up to 85°C.. That's too much, but I don't really think that any real life application is going to hit that strong the CPU. Even VRay rendering is lighter.
- There are so much parameters in the BIOS that I didn't even touch, they are probably other stuff to ajust to increase my OC stability and being able to reduce a little bit the vCore ? What are the others important parameter I should test ? I feel like I have only touch the very essential setting at the moment.
- How much should I run Prime95 Blend test for a real life stability ? My computer will mainly do office stuff, a bit of CGI and have some gaming session of 1-2 hours, it's not going to be part of a rendering farm for Lucas Film
- Does the FCLK frequency OC help stability or so ? Cause performance gain seem so small that I am thinking why I should do it.
Thank for your help and sorry for my english mistakes
