With pumps at the same speed, valve open will allow block and rad loops to act independently. Which, at least at lower pump speeds means the rads will have twice the flow as the blocks. This should bring down DeltaT, but increase block temps due to lower flow rate. With the valve closed, both flow rates are in-line and any excess pressure the rad pump has is added to the block pump, thus increasing block flow. Since your DeltaT is so low anyway (from tons of rads), I would bet you'll get the best results just leaving it all the way closed.

Mad +rep and many thanks. Will play with it when I drain loop to replace the bad fittings; hopefully the box of mayhems gets to me today or Sat.

If you want to make a couple quick efficiency changes without changing your flow design...



The first part is a top-down showing your reservoirs and the two pumps directly below them. I'm not sure if they can fit like this (the second pump may need to be angled ot fit?), but if they can, then both pumps would have direct reservoir feed straight down into the inlet.

The second part shows the cable area after making the other change. You could run your tubes without using any angle fittings going down to the ped, back up, through the flow meter, and to the rad all without angles.

I can come up with some more minor changes like this if you want.

Thanks, I'll look at these. Let's wait on spending more time on this until I verify this isn't self induced due to a borked PWM cable.

Well it's not a bad PWM cable, pulled them out and no change in flow; has to be those 90 degree fittings. I really did want better flow so this means I will have to redo part of the loop once the mayhems arrives, which means I am NOT finishing the cabling this weekend since I need the loop settled. GRRRRR.

I know I could leave it as is, but what's the sense of doing that when I built such a beast setup. It can do better.

So, with MoP dropping Tue it's likely this rig will be on hiatus for a week or two, I'll post again when things mature.

Well I am much happier right now. I decided to work on a real overclock and with offset mode of only 0.015 (plus a bunch of load line and secondary power settings) to get to 4.9 with core temps at 55, and GPU temps at 36. Fans are 40%, pumps at 100, and I am doing a Aida64 stress test with both CPU and GPUs.

Going to let it run over night and if it is still running in the AM then I may just pause here, bask in the achievement and focus on prep for the expansion.

I still plan to try replacing some easy fittings when I replace the leaking ones, but I am no longer considering a massive loop redo.

Po has his fingers crossed for me.

Be careful with how much LLC you use. LLC will allow your vCore to spike when it's idle (even when vDroop is not present). What voltage did you hit 4.9 stable at?
post #347 of 431
Thread Starter 
I am peaking at 1.392 and average is 1.385. Unfortunately it isn't stable, so tweaking things one at a time to dial this in. I am close.

Ok, I think I'm on the right track, did a 90 mins Aida64 stress test including everything minus the drives and had no issues. Part way through Aida64 stopped reporting temps so I had to pull up realtemps to see what was going on with the CPU, overall it was pretty decent.

Here are my bios settings; I am not an OC expert, so if you see a value below that worries you please feel free to say so.

  • Offset 0.035
  • VTT CPU voltage 1.19375
  • CPU VCCSA voltage 1.230
  • CPU PLL voltage 1.825
  • CPU spread spectrum disabled
  • PICE spread spectrum disabled
  • CPU load-line calibration medium
  • CPU current capability 120%
  • CPU power Phase control optimized
  • VCCSA load line calibration extreme
  • VCCSA current capability 120%
  • C3/C6/C7 disabled

Here's a screenshot just before I stopped the test. Note that the GPUs stayed pretty cool as well.



The Mayhems just arrived so I have decided to pull down the loop, make the tweaks Electrocutor and I have been discussing, and finish the wiring.

I think your VTT and VCCSA are too high.
(I would try below 1.15v for both VCCSA and VTT)

I also think you don't have enough Vcore for that frequency. But maybe you have good chip.

I would put CPU LLC to high with current capability to 170%
VCCSA LLC to regular and 140% Current Capability

(Also, don't forget to put the DRAM Current capability to at least 130% (140% to be sure)

Check Raja Guide for better overclocking. Its the best guide for our board, many usefull info in there.

I just stumbled across this build yesterday and finally worked my way through to the end. Very impressive! I'm just starting to look around more at Case Labs builds since I got in on the SM8 preorder a few days ago.
Couple questions when you get time, and if you want to answer them.

Are you using bulkhead fittings for your tubing to the pedestal?
Could you (or anyone who wants to respond) do a ballpark estimate of what an Aquero setup would cost me for 3 rad/2 pump/flowmeter/temp monitoring for my SM8? Just very ballparked, not sure I'm going that route but would love to if I can fit it in the budget.

But anyway a great build, and a pleasure to read.

EDIT: I picked up some more info on the Aquero. Nice system!
