xPU Thermals. Whats burning?

After a small re-amp of a spark (or more like a nuke going off..) for my interest in hardware and tinkering – especially the build and just going expensive LEGO all the over things, I remembered when I once upon a time started, actual heat output wasn’t really an issue – things didn’t even need a heatsink… It was coooool.

Now, when I for the first time ever own _three_  too many AMD Ryzen systems, and since starting to overclock (started with my i5 system from way back (actually, back with my Prescott P4, but nevermind), and non-stock coolers before that ofc.. ), I realized I had never really given it that much thought, just bump some settings and let it roll.
I even been using stock cooling solutions primarily (remember kids, in the server farm, in the way-back machine – stock coolers where cool, and for Intel PII/Celeron with the fancy Slot A config, there were not that many options without a hack-saw). The turn was here – cooling solutions for our rigs with our biiig 80mm chassis fans.. we pushed them hard – dustfilters? Tsk!

They started burning up the place at the same time as (to use a now over used term – VIRAL – ) a video-clip or an actual link to toms hardware where they tested how the stuff worked without a cooler – AMD CPU’s turned into ovens, (Someone got the link on youtube). Fun times!

So, onwards to – graphics.. , NVIDIA and ATI here in the ring already boxing – well, that’s a separate story I can’t really remember, graphics where expensive back then too (right now of the time of writing, it’s silly..). But we started to have quite more umpf being crammed in, and the hype-plane was flying.

So, we are starting to produce more and more heat, and to be honest – airflow was a concept more thought of by putting a big desk fan next to your rig, or pick parts from housing AC equipment.. Around this time (of the Slot A Intel setups), I built my first fan-less rig – as my second server – living under a bed 24/7.. It lived on long – but damn, it was a hard thing to do even back then.

Now however, we have auto-adjusting CPU’s and GPU’s – throttling down clockspeeds when we hit a thermal limit. That works, in a fashion. But we also have power saving modes that clocks down from the get go when you don’t demand that much – we are no longer locked to a specific speed, and we might have a boost on a few cores (yes, this I love) because even tho each core might not displace that much heat, once you cram a few of them together – we have a toasty situation.

Our software, handles this either with some small help. The OS layer just kicks around and becomes the kid that keeps asking for money (or clock-power) – but also the responsible adult that says “that’s it, thanks for the loan”.

The application layer however.. Not that thinking. It’s like the stuckup teenager that just does what ever it wants. Well, usually per instructions of the code and function. But some does concern themselves with battery mode or not – so they do think a tiny bit.

But it leaves an impact window that for us that remember an overall slower process of doing things, at least I get the feeling that I have to wait until it fires off and performs what I asked after all the chains has
(Yes, I have lost the rant-concept right now..).

So, what is really burning? Seems nothing is – we are clocking down, calling things turbo boosting and the clock values are often the baseline where equipment keep the thermal/performance balance the best – even memory does this.

How much impact does these power saving plan have? Does it save us a few bucks on a workstation, or is it that the laptop segment features and trickery simply have ported over?

I don’t know right now. Because this rant is over for now.

The Ryzen 5 1600 / B350 / under linux (kubuntu with kernel 4.15.0-22) and Nvidia drivers…

Every other day one thinks, it’s cool and nice..
And alas – I notice all cores and threads are stuck at 1374Mhz.. No wonder it stays around 41 degrees C over full load..
It seems something is missing in the performance-junka-mado..

However, “clocking down” to a clock in BIOS to 3775 as a max target seems to get it to boost more often and not lock itself down, it finally jumps to a stable 3768 Mhz on all six cores and threads.
Now, the B350 “chipset” is not what I would call anything special, at all. A bit sad that they did a mid-tier chipset that caught most attention it seems.

There’s more… All the AMD chipsets seems to be, not really that fun for keeping score on temps.. One needs to compile it87 as a module to get the values..

All these points are still valid over several updates, and sadly – since it’s first gen ryzen – it’s not new – but I fail to see the light in the tunnel getting all the things working correctly.

Yes, this is a rant.

I am still happy, since it’s paired with a GTX 1060 6GB ASUS ‘blowerstyle’ GFX. It works for all the things I want. But I do want it do listen to my clock settings.. But I am also guessing the firmware is a bit to blame.

And talking about blame.. WHY THE H*CK can’t Nvidia ensure there is fan profiling in the damned locked drivers straight from the get-go? The damn thing clocks down since it reaches max temp before max performance more or less, with the fans locked at half the speed :S.

Rant over.

However, getting the temps is straightforward – . Go and Git it.

Jumping around the OS train. /Rant

All aboard!

Next to me, work laptop turned off for the day – runs Windows 10 (*sob sob*).
In front of me, workstation running *buntu 17.10 18.04 LTS.
Below it, MacBook Pro running Mac OS.
Next to it, my “Pi tower” running rasbian-ish distros.
Next to the screen, gaiming rig running windows 10.
BSD stuffs runs virtual from another location in the apartment.
Chromecast here and there, older i5 and i7 machines littering with a plethora of flavours installed.

No wonder I never get anything done at home, I keep fiddling. And if I am not actually fiddling – I am ranting about fiddling.

For the love of something – no wonder that it’s hard to keep track on where I do what – I am all over the place!

The need to know and to tinker always seems greater than the need to sleep or sometimes do something .. Serious.
Like, being social, or go on a date, or take a walk.. Phaw. No time! So much to tinker with!

/rant over.

Traffic Baseline. Apps/OS.


Many “NGFW” creations looks into the application-stack “layer 8”. I am however pondering over, since many seems to also identify the underlying OS (for enabling better and easier rule-sets per device category for example) – why not also provide a baseline for that specific OS – what to expect and also identify the normally permitted traffic – and the underlying connectionpoints for those. With this reasoning, one could filter out lots of garbage traffic that otherwise needs to be looked at with all the possible UTM-profiles.

This would be something we all could benefit from, make easier exclusions on per OS-basis etc. If we learn what normal is, we do not have to look at it all the time – only in a fully forensic perspective would it be needed – to fully determine a timeline etc.

Progress and success for a company?

Been looking at, a summary over the history of AOL.

The feel I got – was that if you allow marketing to take charge without innovation – you get an AOL history. Doomed.
And – if you get a smaller company with tech-savvy ppl in charge only – you get no growth (based on personal experience).
If you get tech-savvy ppl with a understanding of “what’s next” – you get corporations like google (in the beginning).

But then, think again.. Some inovations press beyond our current boundries. Some boundries are ethical – and those are worse than that of simply “one-step-forward” thinking.

How do you disclose / inform / or get in contact with online companies today?

So, Troy Hunt got the following out;

If we back a bit, we have a communication history in general.
Based on email…


@yourdomain – those where the general in-channels.

Troy got into a tight spot, I have not encountered that – sadly, I got into something worse. Ignorance and fudge..
Reporting anything in a public space – really? How come?

Public space / “social media” is usually under the hand of PR / marketing. Getting ’em to move their butts and report higher … Not the easiest way when we are not talking about security-aware companies.

So how do we determine or detect security-aware companies? We don’t. Bash’em with information – make a correct statement (like Troy and friend did) – and hope that the receiver is not part of the stupidity-bunch.


We broke the internet, by inventing the internet.

Rant… This is a rant.

But in short, by the birth of the internet – interconnected computing, and the applications of that era – why whould not part of the first users take over in a hostile model what they started or, partially took over.

It’s a matter of cost. Looking back at my own involvement with the military – I get it. For low priority stuff you might even hook it up to the interwebs.

But – the problem is, they need to start just do what we do with our normal armies. Stuff ’em as security at the boarder and threatening power. Not enslaving the whole of us. Not stepping on rules, and regulations the majority of us keep. I am not talking about the amount of data. The amount of data is irrelevant. It is the intent of the normal average person connected to the internet. The persona that thinks they have nothing to loose. Nothing to hide, and the worst fear is loosing their smartphone.

Is it really about “defending ours”?

How about it’s time we simply stopped the intelligence community from walking into our livingrooms, and the corporations from owning us instead of us being the consumer of their products.

Time to step up the game, by laying down the rules.

So.. What are the rules?

In war – spare the civilians.

If you have to wage wars on the webs, stop involving us- and our data.

Boho, Netflix and Spotify. Boho, DRM.

I’ve had Netflix for years. Why? I could stream content to my devices – sadly not the devices I wanted to in the beginning, and of course – no “offline” mode. Because, DRM, and… yes. DRM.

Not until Chrome chewed some on it did it expand to the linux platform in a while back. It has never been a great experience, but good enough to hang around for and be able to time to time catchup on series or some odd bad movie you never thought of watching.

Tonight however I just got fed up. I was unable to start streaming anything – because they had decided I was either using a proxy or a VPN connection. Assholes. I was using neither – if any – I did use VPN to get home and be able to watch the same shit as before back in the days when I traveled heavily.

Enough. No more sponsoring DRM and stupidity.

Sadly, I have realized that paying for spotify is not worth it either. I will now save roughly 200 sek (est. US $22) per month, that I can place on other things. Woopie.

The year is 2016….

And all is not well.

But, re-discovered pfSense. It’s grown into a nifty little perimeter protector.
Reverting over to FreeNas – because even at home de-duplication and compression is… useful.
Found myself a small little windows tablet – quite interesting.

The year is 2015 – and people still click without thought.

The year of 2015 – the year one would think that after so many spam emails one would start thinking on what comes into the mailbox.

But no.

It’s tax time in Sweden. Several have gotten spam with attachments, from what claims to be the tax office. It’s not.

First of – they don’t have your email. I don’t care how well thought out and graphically correct it may look.

Second – if you are doing your tax on the internet, there’s several steps to take to just log in – to see your data.
Why on earth would they send anything to your email, with the information ATTACHED?

Thirdly- if you’re getting the spams from DHL – DID YOU ORDER ANYTHING FROM DHL TO BEGIN WITH?


The same way your normal mail works – you open it, athenticate it, and then authorize it. The authorize action along with the authentication can always be verified by contating the vendor in question.


Here’s the tax office WARING

Did you just hover over that link before you clicked it? I hope so.

That’s all for now.
