Why such a dramatic drop in speed?

I did it with a razor blade too.. My man used a bounty paper towel tho??? I used like 10 BD alcohol swabs. Same result, but for pastes, that guys collection all lined up was very cute but I would use Coollaboratories Liquid Ultra (CLU) which is the current recommended TIM for the Die. You have trust this recommendation or you will be a fail. Pastes vs. Liquid Metal are likened to the difference between prime rib and spam. Because the die is small (only 25-30% of the IHS area, a higher thermal conductivity is recommended. Paste = anywhere from 4-10 w/m*k and Liquid metal = ~35w/m*k that is a 3-10x difference depending on what you use. Paste = 5-10°c drop , liquid metal = 15-25°c drop. Do the liquid metal, you will thank yourself later.

GPU-Z is reporting my GPU is running at full x16 but HWInfo is reporting only 8Gbps. Is x16 only 8Gbps?

Could also try TRDWR_sg, TRDWR_dg, TRDWR_dr and TWDWR_dd setting to what CAS is.

I read that on a guide but it is usually only applicable to 3600 + 4 dimms but you could just revert to auto if it does not help.
Sorry for the late reply.

They're 15-17-17-35 sticks, two sets of CMK8GX4M2B3000C15R to be precise.

How far you reckon it's safe to push VCCIO and SA? I'm already at 1.2 on both, DRAM at 1.375 but no dice.

Thanks. I'll try with 1.25 SA and setting those TRDWR numbers.

Are they supposed to be like this?:
TRDWR_sg - 15
TRDWR_dg - 17
TRDWR_dr - 17
TWDWR_dd - 35

No. The third timings are probably not needed. Try the voltages first.

Secondly you could try them all at 15.

Have you also tried auto voltages on vccio and sa?

Right.

Always been wary of auto volts when OC'ing but I'll take your word for it. Complete novice when it comes to RAM fiddling.

Auto tends to be ok for those voltage especially considering you are only at 3000. Always double check what its setting them too though.

Now with regards to the tertiary timing I read on a Ram tweaking guide that it helps with 4 sticks of DDR4 3600+ but as I said it would not do harm in trying if other options are exhausted. You can always change them back to auto if need be.

Do not confuse these with your Primary 15/17/17/35 timings though.

I agree with llantant, setting Auto for vccio/vccsa on my Hero board works out pretty good...right at where my manual settings would be which are a little over 1.2.
I'm OC'ing 2666 ram to 3200 in this case, and having to set the ram voltage at 1.395.

I think he means(?) these.

tRDWR_sg, _dg, _dr, _dd.eg, your last value quoted is not relevant and I'd just forget about them and leave them auto.

The problem becomes apparent with higher frequency RAM, at 3866 it wants to throw in 1.3v when using Auto while 1.21v etc is sufficient (on my chip).
