Yes, it should do that....especially if you clear CMOS.

4000MHz is the absolute top end of expectations on top end hardware...not attainable by every CPU sample...

You could flash 3402 beta with new AGESA to see if that helps...

However as...

tRC

Yep need more volts for that....but this you have to find for yourself...especially combining kits...I'm just giving ball-park figures...a place to start if you will.

At 3600 I found 1.1...

For 3600 you should be good at 1.1 IO and SA....maybe a touch more

Try 14-14-14-28-42....trfc 252.....Something like that...but that will need more DRAM voltage...at least in my experience...
...

If you tighten sub timings you can need more voltage...1.45 is fine if you tighten primaries more...

3600 C14 can be around 1.5..1.6 mark

3600 16 16 16 32 48....tRFC 288/240 should work 1.35 to...

Yep...same cable you would plug to a GPU :)

It's a 6 pin PCIe cable...i.e. 6 pin GPU connector

Aggressive timings will of course make things harder...but a lot of that is trial and error...

You might find 3600 tight timings beats 4000+ with the timing compromises and voltages

3600 should...

Combining kits can already give you these problems....pushing over 4000MHz may add more

I'd try one kit and see what you get...both kits may run 4000 with 1.3 IO SA...maybe only 3600

Maybe download a fresh file of latest BIOS and reflash that

There is in fact USB BIOS flashback...so just use that

Maybe reflash latest BIOS with this method since it works fine on all impacts I've tried....

02 means it's sitting in BIOS I think...check your display chain...gpu... cable... monitor

Maybe flash latest BIOS ....BIOS flashback method

Yes...that should be fine

Yes that works....just select PCIe raid mode for the x16 slot you mount the card in....it says raid mode but they will work as 4 separate drives....

With the obvious caveat that it depends on...

Check the way the board is mounted...contact etc...and if you have a spare PSU check that...check the correct power cables are connected

That should be OK. It really depends on you finding the maximum airflow through your case.

Good fans on an AIO are a must but both your choices come with good fans so...

Just balance intake...

Probably the PSU if board and CPU are fine...or the connections from the PSU

If the board supports it "BIOS Flashback" method is the most reliable ....followed by EZ Flash utility in BIOS

Have tested this thoroughly with various CPUs and boards already....works great

New AMD chipset drivers out too...

All fine for my testing

I haven't got around to this yet...too busy...but you might look into VF offset curve.....looks like that might be the way to do it...?

Crosshair VIII is a good board...the revision coming for 5xxx series CPUs looks to be a very nice board,,,finally ASUS putting in the effort on AMD

Nice one....they are workhorse GPUs when nothing fancy is needed :)

No...i'm just suggesting a range of voltages to try...manual

Connect the pump header to AIO header...

Connect fans to CPU header...or set CPU header to ignore monitoring if you are powering fans by some other means
