Watchguard Firebox M400/M500

@stephenw10 No, the i3-4370T has the reboot hang issue. Not a big deal as instead I just do a HALT, then power off and on with the button afterwards.
I'm measuring with an Emporia outlet device. At 1% load, I'm mostly idling. If SpeedStep is significant (e.g. drops it to less than 10W) it would be a worthwhile update, but I have no idea what to expect by enabling it.

Enabling high C states usually has a greater affect, especially if your CPU is mostly idle.
Check the available C state and the 'lowest' value. The default Celeron and BIOS don't offer much:[2.7.0-DEVELOPMENT][admin@pfsense.fire.box]/root: sysctl dev.cpu.0 dev.cpu.0.temperature: 39.0C dev.cpu.0.coretemp.throttle_log: 0 dev.cpu.0.coretemp.tjmax: 100.0C dev.cpu.0.coretemp.resolution: 1 dev.cpu.0.coretemp.delta: 60 dev.cpu.0.cx_method: C1/hlt dev.cpu.0.cx_usage_counters: 66905813 dev.cpu.0.cx_usage: 100.00% last 620us dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_supported: C1/1/0 dev.cpu.0.%parent: acpi0 dev.cpu.0.%pnpinfo: _HID=none _UID=0 _CID=none dev.cpu.0.%location: handle=\_PR_.CPU0 dev.cpu.0.%driver: cpu dev.cpu.0.%desc: ACPI CPU -
@stephenw10 Sounds like it may be worth a try. I may try to pick up another M400 so I'll have a backup and maybe try to "downgrade" it to a i3-4130T as well. Lower clock should use less power and I hear it doesn't have the reboot issue so a win-win. Might also upgrade that machine to pfsense 2.6 as I'm on 2.4.5 currently.

With an i3-4160 and unlocked BIOS to enable speedstep:

That CPU doesn't reboot though so upgrades are a PITA!
-
@stephenw10 Oh, the i3-4130T is also on the reboot naughty list? I thought someone had posted in this thread that the 4130 was OK?
-
@stephenw10 Oops, ignore my comment - just realized you were posting about the 4160 and not the 4130 re: reboots. I just bought another M400 on eBay for $50 and ordered a i3-4130T for a whopping $10! I'll probably set that up from scratch then swap firewalls keeping the current as a backup if I don't brick it doing the bios update.

With Xanthos fully unlocked BIOS you can enabled higher C-states:

Idles at ~24W.
The CPU claims to support higher C states but pfSense doesn't see them. -
@stephenw10 Just finished downloading Xanthos' files and various instructions posted between him and yourself. Do you think disabling the i3's iGPU in Xanthos' unlocked bios will reclaim a few watts?
Too bad it wasn't possible to get the 13W Xeon to work, that would have been crazy.
-
The TDP rating of a CPU is only a guide to the cooling solution needed to run at full power. It does not tell you the minimum power consumption. Whilst the lower TDP devices usually do run at lower idle power it's often not by much. No where near what you might think if you only look at the TDP.
Using a CPU without on-board GPU can save a few Watts, I've tested that on earlier gen CPUs. I'm not sure if disabling it does much though. On more recent devices other users have demonstrated that loading a graphics driver that can put the GPU into an idle state can produce a decent saving. -
@stephenw10 BIOS update successful, but I have an embarrassing question - how do I install pfsense? ha ha
The last time I did it was when we had nano-bsd images and now we have the memstick images. I RUFUS'ed the image to CF, inserted it into the M400, booted, select install, select keyboard, then I get stuck when asked to partition the disk. ZFS takes me down some RAID path, UFS BIOS says "device busy", UFS EUFI also says "device busy". Any pointers?
Thanks!
-
@eisenb11 oh, nevermind - I just had to try a few times and it moved forward.
-
I have an M400 which I have tried to flash with Zanthos' BIOS. Have used a CH341A SPI Flash Reader and ASprogammer. When I start up the Wathguard it is on for 3-4 seconds and then it turns off again. Is there something I did wrong or has the flash itself failed? It said that everything was successful.
-
Hmm, that's not good. Could be either with those symptoms.
You might try re-flashing it. Or restoring the old file if you backed it up.
-
@stephenw10 Tried to reflash and restore back to the original BIOS without success. Have also tried another PSU, but with the same result.
-
Hmm, not sure what else to suggest. Had you swapped out any hardware before that?
-
@stephenw10 Have not replaced any hardware. It should be said that I tried a long time ago to flash the bios with software flash with Zanthos' version and that's when it failed. Finally ordered an SPI reader and thought it would work. I extracted the original BIOS from an identical M400 that I have that works. It might not work?
-
I would expect it to work. It's possible you had a hardware failure that happened to coincide with the original BIOS flash attempt of course. Seems pretty unlikely but....
-
@stephenw10 Tried to find a detailed overview of the motherboard, but can't find it anywhere. Do you know where I can possibly find it?
-
The Lanner FW-7585 manual is the closest you're likely to find. It's not exactly the same but close enough.
-
@stephenw10 Thank you very much! Will have to see if I can get the M400 to stay on.
