I have been working on overclocking my RAM to 3600MHz and running the AIDA64 Cache & Memory benchmark to test memory latency. Typical values are around 55ns but my mem latency has consistently been about 10ns higher. It was suggested to me on the Overclock.net forum to try booting into Safe mode and repeating the latency tests. I did so and the mem latency dropped down to ~55ns - right where it should be. So I booted back into normal mode and started shutting down apps in the system tray. I have a bunch of them but found that quitting them had no effect on mem latency except for Aquasuite. When I shut down Aquasuite and its service, the mem latency immediately dropped about 5ns. I have not figured out what is causing the other 5ns of increased latency but Aquasuite is causing mem latency to increase by ~5ns.

Is this is a known issue and to be expected? Is there anything I can do to minimize the effect Aquasuite is having on memory latency?

Try to disable the hardware monitoring of the Aqua Computer Service. You can do this in the aquasuite settings for the service.

Anyway: Benchmarking memory latency is more witchcraft than science....

Thank you for the suggestion but I already have all AQS hardware monitoring disabled. Everything comes in from HWINFO.

Yes benchmarking memory latency is not an exact science. I am only running latency benchmarks to see what effect changing various RAM timings has. I am trying to get my G.Skill F4-3200C14D-32GTZR 2x16GB 3200CL14 B-Die kit stable at 3600MHz with minimal latencies. I found some other posts stating that running AQS and its service adds 3ns to 5ns of latency. I guess its just the way it is. I am not doing anything with audio or video, and have all AQS hardware monitoring disabled. I don't see what else I could do to minimize its effect on memory latency.

Unfortunately no. I was no able to find a way to decrease the amount of latency that AQS seems to add. I did get my RAM stable at 3600MHz but had to leave some timings looser than I would like. AIDA64 shows my memory latency sits around 65ns with AQS running.

I see. Thanks for reporting back.... You running Ryzen? Cause that would be too high for intel on that kit I would imagine.

Yeah a 5950X and 2 x G.Skill F4-3200C14D-32GTZR running at 3600CL14.

I think it depends on 3 things.
1 - What Aquacomputer hardware you have - do they have micro-controllers and a functional Aquabus port?
2 - Aquabus configuration - can you physically connect all of the slave devices to the Aquaero?
3 - Are you are using any data that can only traverse a USB connection (RGBpx for starters)?

I don't have an Aquaero, but my understanding is that it contains it's own micro-controller and can run autonomously without AQS or it's service. Devices like the Octo, D5 Next, Highflow Next, and Farbwerks also have an on board micro-controller so they can perform functions based on sensor data coming directly into the device (temp, flow). I think they can also react to sensor data coming in from other devices that are connected via Aquabus.

If your other devices are all connected to the Aquaero 6 pro via Aquabus, and nothing you are doing in AQS requires data over USB, then I think everything can run without AQS or it's service running. You will lose RGBpx capability on the Aquaero, and you will not be able to do things like control LEDs based on audio or video, some alarm functions, Windows notifications, etc. Also, not sure if you have 2 Farbwerks or 2 Farbwerk360s. The Farbwerk (12VDC LEDs) has a functioning Aquabus port. The Farbwerk360 (5VDC LEDs) has an Aquabus port but the manual says, "Reserved for future use, no compatible products available as of April 2020". I don't know if they have since activated this port. If not, the Farbwerk360s can still run and react to the 4 temps sensors and the flow sensor that are on the device, but they could not react to anything outside of themselves. You may also need to get an Aquabus X4 #53258 to get all of the Aquabus ports wired up to the Aquaero (if they aren't already).
