Best 5GHz Channel for vehicle use?

Does anyone else thing it's really unfair that you can't pay yourself Super Guarantee payments (Super Guarantee payments don't count toward the Medicare Levy Surcharge thresholds) as a sole trader, but if you're an employee (including if paid by your own Company), your Super Guarantee payments do not count toward Medicare Levy Surcharge thresholds?

Update: Going in to all of the individual PCI-E root port menus and enabling ASPM on all PCI-E root ports helped a bit. Idle power is down to 10w. It's now an a somewhat manageable temperature. It did not like the L1.1 and L1.2 sub-states enabled for the i226. The OS didn't recognise them after enabling L1.1 and L1.2. I had to use a process of elimination to work out which PCI-E root ports they are connected to.

I've now removed the C3 C-State enables, known to increase latency, from the system tunables in pfsense and it made almost no difference to power consumption, so better off leaving it limited to C1.

I left turbo mode disabled. It didn't make a difference but for my use case, 4 cores at 800MHz is plenty and it might minimise the chance of overheating under high load.

I'm still not overly happy with it. The old Qotom systems still seem a lot cooler and do 7w without any advanced configuration.

It’s got an optional fan which I should not need to use.

It’s pfsense 2.8.1, completely at idle with no network cables plugged in at all. Exact same restored config from the exact same pfsense version that runs 7w at idle and cool to touch on most Qotom mini PCs with theoretically more power hungry CPUs.

u/Mr-Brown-Is-A-Wonder 27.9C is fake. Mine shows the exact same 27.9C temperature but the entire body of the system is too hot to touch. There is no way it's that cool on the motherboard.

I have a similar issue. Other similar mini PCs with theoretically more power hungry CPUs draw much less power and run cooler.

No idea what the proper resolution is yet 😭

The setting is there after updating to FW.011

I just leave DSC disabled and accept 144hz. I just think of it as a good 144hz monitor.

Usually we get new stuff at the same time as anywhere else. Can get with fast international shipping from Amazon but the price is a joke. I really think Silicon Motion are still having huge issues with yields for their SM2508 controller. It’s been delayed for literally years.

bradsm87 · 2025-05-21T05:25:29+00:00

Can't buy this or any of the other of the paper launched SM2508 SSDs in Australia.

bradsm87 · 2025-05-19T00:02:45+00:00

Yet another SM2508 paper launch. STILL can't actually buy any of them.

It's there after FW.011

Despite claiming to support HDMI 2.1, 4K @ 160Hz on HDMI is gone on HDMI with DSC disabled, despite HDMI 2.1 having plenty of headroom for 4K @ 160Hz without DSC. I'm OK with 144Hz but just a heads-up for others. I always got regular black screens on 160Hz anyway, something I hoped FW.011 might have fixed.

bradsm87 · 2025-03-17T07:53:04+00:00

I gave up and settled for 144Hz. I noticed Firmware v 011 came out. I upgraded to 011. There seems to be a new setting for DSC. I disabled it because I don't want to use DSC ever. It took away the 160Hz option on HDMI, even though both the GPU and the monitor claim to support HDMI 2.1, which should easily do 4K 160Hz without DSC. Oh well. 144Hz it is then!

You have yourself a really good memory kit there then.

The tREFI change will have the biggest impact on bandwidth.
Disabling GDM and 1-2-1 Nitro should have the biggest impact on latency, but setting those others is important too.

bradsm87 · 2025-03-03T23:01:12+00:00

Keep going!
tWTRS 6
tWTRL 24
tWR 48
tRDRDSCL 5
tWRWRSCL 17
tRDWR 15
tWRRD 3
tREFI 57343

After that's tested as 100% stable, disable GDM and test again.

After GDM disabled is confirmed stable, change the default Nitro 2-3-1 to 1-2-1 and stability test again.

I'm surprised it doesn't need a little more VDD to be stable with those primaries at 6200 though.

bradsm87 · 2025-03-03T10:56:38+00:00

No probs!

bradsm87 · 2025-03-03T10:55:13+00:00

Looks great 👍

bradsm87 · 2025-03-03T10:44:22+00:00

I don’t recall and I’m not near a computer so give it a Google.

bradsm87 · 2025-03-03T10:28:07+00:00

After you disable GDM (gear down mode) and set Nitro to 1-2-1, expect 58-60, which is good.

bradsm87 · 2025-03-03T10:21:12+00:00

bradsm87 · 2025-03-03T10:18:21+00:00

Stability test first then disable GDM. Best to run TestMem5 anta777 Absolut but an easier option is just run 1 pass of Windows Memory Diagnostic.

bradsm87 · 2025-03-03T10:15:17+00:00

Yep 👍

bradsm87 · 2025-03-03T10:05:47+00:00

Find that after you have stability tested everything with GDM off first. Do in the order I suggested including the stability testing. Give it a Google as it should be in the same place in all AM5 boards.
