Full bank is not a problem for Ivy as long as your mobo/BIOS supports it and there's enough clearance between CPU cooler and the closest DIMM slot you would be fine.

Well done. Looks like your chip loves more voltage for 4.5. Try upping vCore to 1.3-1.35v, if your cooling still permit. One if the culprits is your mobo has a bad VRM quality, which results in high vCore.

1.365v during load or idle? If you are just increase CPU from stock clock to 4.6 without touching other settings such as RAM then insufficient vCore is the only suspect. So, try upping your vCore, notch by notch.

I couldnt see what vCore & load line calibration aka LLC are actually actually set perhaps you should try my advice above, increase your vCore.
Good luck!

The voltages could be adjusted better if I got time later.

That board doens't have a lot of the overclocking features of many of the higher-end boards including manual vCore adjustment & lack of power phase.

You might wanna go through THIS GUIDE for more overclocking tips on this board.

Although the CPU is 2600K, basically can be applied on 3770K as well.

New Bios Available for ASUS Maximus V Extreme: 1604

As referred to THIS GUIDE, it is possible.
But why dont you try it yourself and share with us.

Could be memory issues. Did you overclock your RAM?
Don't do it at the moment. Check out your BSOD the nvlddmkm.sys is related to nVidia graphic card.
You should update your graphic card driver.
Besides that insufficient vCore also might cause the BSOD, try upping vCore to 1.35-1.4v, if your cooling still allow.

Tjmax is 105C, so it is still safe to increase the vCore.
The RAM you can always set to rated speed/timings manually, but advice don't touch anything on memory first before you got the CPU overclocked stably.

It is a good TIM but outrageously difficult to apply due to its stickiness.
MaximusPC suggested it performs better than Arctic MX-4.
But I'd highly recommend Coollaboratory Liquid Ultra. From my own experience Liquid Ultra is 9-10C better than MX-4. Proof

Suddenly felt boring just now. Decided to delid my 2nd chip which is IMC 2800+ capable.

So this is the b*tch I bought for RM1.5k+ few months ago,


IHS was beaten by a big size stationery knife within 5 minutes! It was quick.


The residual black adhesive is removed by my fingernails,


Applied Liquid Pro (elder bro of Liquid Ultra) on four sides: CPU die, IHS top and bottom, waterblock base.
Note that IHS is installed, hence the CPU is not running nakedly

So, here's the results. Looks impressive, now with a 2800MHz rated RAM kit


I believe that LinX is still possible on this chip. Stay tuned.

Glad to hear that you managed to get rid of that BSOD. Hopefully the current settings serve you well. So I think it's due to insufficient vCore.
The FSB:DRAM = 1.1 most stable is not true and baseless especially when you're dealing with integrated memory controller (IMC) built on the current architecture.
After looking at some of my rigs, with BCLK (FSB) 100, these are what CPU-Z shows for FSB:DRAM; 1:9, 1:10, 1:11, 1:13, 1:14. The biggest factor has a lot to do with what the CPU's IMC can support & handle those RAM frequencies.
To cut a long story short: My advice is to get the best RAM and CPU one can get to get the best performance. And don't mind no ratios.

Liquid Pro is better, but it's not available locally.
You must import Pro from Coollaboratory website.

No, any Ivy chip can easily hit 5.0GHz, with proper cooling of course.
And your BSOD is caused by insufficient vCore again.
So pump more juice to it.

You better stop at 4.7 or 4.6. Run some stress tests posted in Post #1.
Good luck

Memory/RAM related.
Could you pls show us your BIOS settings especially the voltages & timings.

Since it's memory related issue you could try to bump up DRAM voltage (vdimm)
Obviously timing is referring to DRAM timing control in your picture.

1.5v
9-9-9-24
Command rate 2N

Let the subtimings set to auto.

On stress test as long as it's below TJMax 105C then you should be fine because in daily routine works you will not hit this kind of temp.

There are several ways to reduce the heat/temp:
Upgrade to a better air cooler/fans or watercooling etc if got budget
Reapply a better thermal paste
decrease vCore
decrease CPU PLL voltage
Buy a case with better airflow
If you dont mind to void Intel warranty, delid the internal heat spreader (IHS)
Etc....
