When specifying an offset voltage, it is applied to what the auto voltage would have been so you can make it go either higher or lower than the auto voltage by specifying a positive or negative offset.

Remember, the auto voltage comes from the VID which is the processor continually telling the motherboard how much voltage it wants at any instantaneous moment for the speed, load and types of instructions that is happening then. This allows the motherboard to more accurately track what the CPU thinks it needs.

An advantage of using "offset" (which is called "adaptive" in some other motherboards) instead of "fixed" voltage is that when the load is lighter and the CPU doesn't need as much voltage, the motherboard can down voltage and use less power and create less heat.

If you have a successful overclock, please post the following:
  • Motherboard
  • Clock speed
  • Type of cooler
  • AVX offset
  • CPU voltage setting (either manual or adaptive)
  • VCCIO and VCCSA voltages (which seem to effect CPU temps)
  • Observed CPU Voltage from HWInfo64 (VR Vout or VCore if no VR Vout) when stress testing
  • What stress test you did
  • Max core temperature during stress test
  • Uncore/cache speed

If you have a question about your system, please include as many of the above as you have in your question.
I would change the thread title to "Overclocking i7-9700k Results and Questions" for more hits on this thread.

Did you get a replacement i7-9700k from Silicon Lottery yet (or am I confusing you with someone else)? If so, how's it going?

I returned my i7 9700k to silicon lottery, now I'm going to try retail waiting for a sale on the i7 9700k the prices are to high. MSRP is $374.00

Yeah, prices have ticked up a bit. I paid $409.99 from B&H in early Dec. They are now $434.99. From the discussion here on overclock.net, I would have thought that more people were going for the i9-9900K and that few were buying the i7-9700K, but apparently there aren't lots of i7-9700K's sitting around or the price wouldn't be up. Perhaps Intel underestimated demand and didn't make enough?

Maybe the i7-9700KF will affect things somehow when it hits the market? Unless it is somehow demonstrated to be better at overclocking, it has to cost less even though list price is supposedly the same.

Yes the demand for the i7 9700k is high or supply is low, the pricing shows that since Intel MSRP $374.00. Hopefully I can see more examples in this thread on how well the new batches are overclocking.

z390 Aorus Master Gigabyte
5.0G/4.9AVX
h115i RGB ¨Platinum (280 AiO)
Avx -1
1.365 vcore in bios with LLC Turbo
VCCIO/VCCS Auto
4.3G Uncore

Using 4*8 GB GSkill Trident Z RGB (rated 4266) @4000Mhz 1.4v 19/19/19/39

Idle:38°
Cinebench : 72°
Prime 95 With AVX and SmallFFT 99°

Seems to be an average quality from silicon lottery
A bit disappointed that i can't reach 5.1 or 5.2 without stability issues, but 100% stable with 5.0/4.9avx

Maybe this sounds counterintuitive, but I only got 5.1 stable on my 9700k when I went to adaptive mode (with an offset voltage) instead of fixed voltage. I don't know if I just wasn't trying a high enough fixed voltage or if there is something else in play. I always wanted to end up in adaptive voltage anyway so this worked out nicely for me.

What timings was your DRAM set originally rated for?

What led you to lower the uncore speed?
