8700k - did i just win the lottery?

[ElBurge]

So bit the bullet and upgraded my Haswell system to Coffee Lake. Just got done building and rehooking up my EK loop.

Threw in a quick couple of overclocks - Im stable at 5.2Ghz with out any messing around, on 1.3V and 80C under stress load (Max temp hit 83).

So - Im going to keep going but i just read so much that these chips run hot, and that they need 1.4v... and even de-lidding to get anything decent. Is this just a load of crap or did i get a good chip?

Only tested with Realbench for a couple hours, all went well - but i guess i spoke too soon as i did get a couple crashes on BFV. Upped the vcore to 1.35, its running at 85C but peaked 93c under stress after an hour -

....although i did whack my old numbers back on to Precision x1 on the 2080 without starting from scratch again on the new system, so i probably want to stop skipping some steps and spend some time on this, as it may have been the GPU causing the crash during BFV.


8700k @ 5.2Ghz
EK supremacy block 280 + 120 Rads
RTX2080 FE @ 2055Mhz
Asus Maximus Hero X
16GB G.Skill 3000mhz Trident Z
AX860i PSU

Can i tell the batch number without taking off the block? - can CPUZ read it?

AVX off-set is 0

tell a lie AVX offset is 1

Dont have timespy extreme but yea can complete non-extreme bench

Took the OC off the GPU and everything seems fine [email protected]. On Timespy peak max was 85c.

I have also took the offset off altogether so its 0

Oh my... I just delidded my first chip. 5.4 @ 1.4v.... bsod at the last min of timespy lol. ..... Watch this space....

5.4 @ 1.42 - 72C peak on the CPU with it sat in the mid 50s most of the run.

Ok i bumped up the cache to 52 and upped the voltage to 4.5v but i am pretty much matching your CPU score. I also looked at older much lower clocks and theyre much lower scoring - so i dont think its a stability issue? What RAM are you running? I have 3000mhz @ 3200mhz.
We have the same boards so interested to know what your other settings are?

Ive stressed this in real bench and its fine.

Yea I hear 3d mark loves ram!
