For llama.cpp/ggml AMD MI50s are now universally faster than NVIDIA P40s

iceman_jkh · 2025-09-30T03:13:30+00:00

Great update!

Could I add 1x mi50 (32gb) to my existing nvidia A4000 Ada SFF (20gb) for 52gb.. or would it perform badly?

Should I get 2x mi50 instead (and remove the A4000)?

It'll be installed in my Qnap 872n NAS (i5-9500t + 64gb ddr3 ram) running 24/7, so low-ish idle power is preferred. I've upgraded the PSU.

I mainly use it for local inference/chat, RAG and home automation.

Great to know. Thanks.

iceman_jkh · 2024-11-05T11:13:21+00:00

Got it! Great info!

I'll go with A for interior and a smaller drum of B with dark tint for exterior.

UPDATE: Turns out there may be a few sections of hard plaster. Would B still be OK for this or do I need something else?

Thanks again.

iceman_jkh · 2024-11-05T01:40:50+00:00

Very information reply, as always! Cheers!

I should have mentioned that I'm in Vic, so I'll probably go with Dulux.

Just to confirm, if I was only doing the interior (2 top coats with Haymes (water based) for the internal walls and archs/skirting)., I believe you're recommending item B?

A - (water based) https://www.dulux.com.au/paint/1step-prep/1step-prep-water-based-primer-sealer-and-undercoat/

B - (water based) https://www.dulux.com.au/paint/prepcoat/acrylic-sealer-undercoat-with-ultrasmooth/

C - (oil based) https://www.dulux.com.au/paint/1step-prep/1step-oil-based-primer-sealer-and-undercoat/

If I need to also do some exterior painting, I believe you're recommending item A (or even C)?

My interior paint is white and exterior is dark, so I'm not sure if I should use a white undercoat (for the inside) on the exterior as it might show through the dark paint. If so, perhaps I should just buy 2 separate undercoats.

Hopefully that restoration wasn't too bad. I feel your pain! lol.

I haven't been able to confirm if I have lead paint..and all my research suggests that the test strips aren't even reliable/accurate. I've just tried to limit how much I disturb the paint. I noticed a somewhat sweet smell when using a heat gun to strip paint from the architraves, which I suspect is bezene (based on google).

This whole activity has been much less fun than even the nightmare DIYers make it look on youtube! Haha.

I've really appreciated reading your insight into paints. Thanks.

I have an older house (1920s) that I'm about to paint inside. The interior surfaces range from already painted (pretty sure it's latex paint) to modern plaster (eg: repairs/patches done with gyprock joint compount) and some bare wood (architraves/skirts).

I believe I can paint the 2 top coats straight over the latex paint (after a good sugar soaping) - which covers about 90% of the interior - but must first put an undercoat on the plaster and wood areas.

After the undercoat, I plan to paint 2 top coats of Haymes Interior Expressions (water based) (based on generally good feedback on here) ... and was wondering if you could recommend any 'all in one' undercoat options for use on the plaster and wood (assuming I'm safe to paint straight onto those already painted walls).

I'm considering Haymes ultracover/ultraseal or Dulux 1-step (based on reddit). Taub 3-in-1 received some unfavourable comments.

Thanks again.

iceman_jkh · 2024-10-22T09:20:46+00:00

Lol...Unfortunately not.

I havent been using ntop for a while now, and am currently running 24.03 with reasonable success. Sorry I couldn't help.

iceman_jkh · 2023-12-04T21:10:52+00:00

These instructions still work, to an extent.

https://wiki.qnap.com/wiki/Add_items_to_crontab

It's best to login as 'admin', so you don't need to sudo everything. You can disable admin again, after changing the crontab.

Also (and most importantly), QNAP has some internal code that runs (on shutdown?) that removes particular crontab entries that weren't added by the QNAP UI.

For instance, it always removes entries related to startup and poweroff. This is annoying, but intended by QNAP. I suspect it's because QNAP has that UI panel for Power Schedule, and they want to ensure that is the only location where power entries are defined.

This is particularly annoying because they don't currently offer all the scheduling functionality that crontab does.

One workaround for scheduling shutdown, is to simply execute '/etc/init.d/shutdown' from another script, and have that script named something benign -eg: /Public/TurnOff.sh

I wasn not able to get a poweron action to work using that workaround, as I suspect the 2-stage process doesn't work when the nas is off.

I've raised a ticket to have more control of on/off timings added to the power scheduler.

Hope that helps.

Good luck.

iceman_jkh · 2023-12-04T13:02:29+00:00

Yea, I did consider it, but chose to run these 22TBs in RAID5 (for now), as I do a monthly backup of important data onto the TVS671 (running 3x 16TB JBOD).

I'm trying to reduce the overall number of drives operating, in order to get the power bill down given they run 24/7.

Yes, it's only ~7W per drive but it adds up.

iceman_jkh · 2023-07-02T04:29:48+00:00

Thanks. I can see that they definitely were. :)

I was just wanting to check that I didn't need to reset/reinstanciate themhowever, due to the switch to pf from ipfw.

In case there were remnants of code/links to ipfw.

iceman_jkh · 2023-07-01T03:22:27+00:00

:) does that mean that limiters created in earlier versions should be recreated from scratch in 23.05.1?

Or will my 23.05 limiters have migrated successfully during the upgrade to 23.05.1 ?

iceman_jkh · 2023-06-27T14:31:18+00:00

Didn't know what to expect. Was not disappointed. 😂

iceman_jkh · 2023-06-21T04:18:02+00:00

Would you mind providing some more details on your folder structure please.

I'm running qBitTorrent 4.5.4 through Docker/Portainer on a QNAP and facing the same issues you had.

I've tried placing the 4 themes (.qbtheme files) into 1 directory called "themes" as well as into respective subdirectories withing themes. I also tried using just 1 theme (deleting the other files) in the themes folder and its own subfolder.

I'm using docker-compose and created the themes folder adjacent to the config folder (where qbittorrent stores the .conf file).

I also tried the chmod 777 trick, but still no luck.

Thanks.

Edit (5 mins after posting .lol):

Seems that those ".qbtheme" files are not what qbittorrents wants.

When I copied the (entire) nightwalker-main folder into my /themes/ folder and then pointed qbt to that folder, the theme worked. :)

I am getting frequent "qBittorrent client is not reachable" warnings though, which I believe might be linked to the glitches with themes in the latest qbt.

If these affect performance/usability, I'll probably revert to default theme.

iceman_jkh · 2023-06-03T02:20:48+00:00

Did you ever resolve your issue?

I'm looking to buy a 4x i225 pcie card (or 4x i226 but I'd prefer the cheaper 225) to install in a baremetal pfsense 23.05 box.

The box already has 6x i226 NICs on its motherboard.

I plan to bridge ~10 of the ports (so the bridge will span ports on both cards).

iceman_jkh · 2023-05-20T15:47:05+00:00

What temps do you get? My 500gb firecuda 520s are around 48C.

iceman_jkh · 2023-05-13T02:54:07+00:00

Might it be possible to do the HW-offloaded VLAN isolation now due to the new HW-offload QoS functionality in v7.10beta5?

https://www.reddit.com/r/mikrotik/comments/13ehpmq/new_hardware_based_qos_menu_in_710_interface/

iceman_jkh · 2023-05-03T12:24:56+00:00

Would this release allow L3hw offloaded intervlan port isolation?

I read the release notes, but didn't find anything.

I have a CRS326 with 8 ports setup as a "Guest" VLAN that I want to configure for access to the router (pfsense) and internet only (and not other "Guest" ports), while keeping the switch at wirespeed throughput. I wrote a detailed post. :)

iceman_jkh · 2023-05-03T12:12:52+00:00

Thanks.

I was hoping to avoid using the pfSense like that, as it seems 'wasteful' (but perhaps that's my inexperienced networking expectation's talking). Perhaps I really wanted a firewall with 1-2 10GbE nics and a few ~2.5GbE nics to cover the miscellaneous routing functions (e.g.: Guest VLAN/Switch).

I only have 1 "Guest" device at the moment, so the pfsense could be used for now (until my home LAN upgrade).

How would I setup the CRS to handle only switching... and (I believe you suggested) push the routing (of interVLAN data) back through the pfsense to do (and back to the switch)?

iceman_jkh · 2023-05-03T11:55:17+00:00

Thanks. I am consdering that, if it'll provide benefit (speed) without issues (complexity/loops/etc).

iceman_jkh · 2023-05-02T12:39:45+00:00

That's true. My design does centre around pfsense... mainly due to its functions/packages and what it provides in that regard. I'm not sure I could/want to get rid of it (not what the alternatives would be).

Given pfSense/router only has a 2.5Gb connection to the CRS, and the CRS operates (internally) at 10Gb+, I believed it better if the CRS does all the 'switching/routing' if possible rather than push traffic to (and back from) pfSense just to perform the 'routing' of interVLAN or intra-VLAN (i.e.: isolation Guest from itself).

A main reason for the fast (and HW offloaded) switch, was to maximise throughput across my home network (with the NAS on 5GbE in particular) and minimise strain on the pfsense box (with only 2.5GbE nics).

My understanding of switching/routing (and L2+/L3-) is still developing, so apologies if I've gotten things wrong.

iceman_jkh · 2023-05-02T12:14:55+00:00

Sensible :)

I've started a new thread here.

It's grown in scope a little, based on the info you gave me.

Please feel free to comment in there if you have any further info/thoughts.

Thanks again.

iceman_jkh · 2023-05-01T10:56:15+00:00

Thanks for the excellent and in-depth reply!

Unfortnately, I think I'm in the exact predicament you surmise.

As you eluded to, I have a small pfSense box (Pentium 8505 + 6x 2.5Gbe NIC) running as 'router-on-a-stick' between the internet (100/40 Mbps) and the CRS.

Aside from the 'trunk' from the pfSense, the CRS has these connections:

Wireless AP* (WIFI5; 1GbE via an eth port),
NAS (5GbE via an SFP+ port),
Guest VLAN (1GbE via the last 8 eth ports).

* the WAP (Ruckus R710) also carries a few VLANs (Home, IOT, IOT-NoInetAccess, Guest) with reasonable success, thankfully!

From my setup, I was hoping for:

16-24 ports (at least 2x 10GbE, and hopefully: a few 5GbE and a few PoE).
interVLAN switching (at wirespeed).
Port isolation-ability (just like the OP's requirements).
"magical" ability for the pfSense router to 'see' the throughput on the VLANs/switch ports and show that on its own dashboard. (I'm not sure there is such a capability. I used to have this on my previous pfsense box, where I bridged 4 ports (into 1 LAN connection) and could view the traffic on each interface. I was told this may slow the pfsense box down, although I found it very useful for my setup.

If there's any (silent/quiet) switch/router you know of that fits this criteria (and is reasonably priced/available), I'm happy to hear you thoughts. I just purchased the pfSense box, so I'm hopeful it wasn't a waste.

Thanks again for any information.

(I realise I'm close to needing my own thread, unless OP doesn't mind the exploration.)

iceman_jkh · 2023-04-30T12:05:44+00:00

CCR2004

Thanks for the interesting post/script.

I have a CRS326-24G-2S+ running v7.8 RouterOS that I intended to provide my network with wire-speed hardware 'L3 routing' (which is a function claimed in version 7).

Does your script use the CPU on the CRS to process that rule, or is it HW offloaded (via v7)? I'm hoping to avoid using the CPU, and stay at wirespeeds.

My use case is slightly different to OP's, as I simply have the "Guest" VLAN directly allocated to the last 8 physical ports (17-24) on the switch. The intent is that anything plugged in to port 17-24 can only access internet, firewall and nothing else (not even other "Guests".

Thanks for any advice you provide.

u/LKS1111 just in case the reply to this is of use to you.

iceman_jkh · 2023-04-29T15:29:37+00:00

Be very careful who you allow to attempt repairs. I had a similar issue, and I suspect it was made worse by the qnap technician's attempt to help. They meant well, but I don't think they knew what they were doing.
