Heya Folks,
Today is the first time I saw RandomHash in action, it was quite amuzing (why is secret for now). Unfortunately my main CPU is probably a bit too slow to compete with modern CPUs though with a bit of luck maybe some mining can be done, or maybe some parts of the randomhash can be executed on gpu
though I am not yet sure if there will be CPU-mining pools I would guess so which might make mining with a single CPU useless anyway.
However that is not the main reason I am writing this.
The main reason is this:
I just tested the new miner on a very shitty german laptop which I got for free from somebody... I ran multiple miners on it... and after only a few minutes the laptop shut off... it probably got to warm.
This is a little bit alarming really ! Cause this laptop was able to game, but somehow it shuts off... I did kinda let the laptop fall while setting it down near a candy carnval shop not sure if that has anything to do with it and it also has driver/IRQ blue screen issues probably cause I stopped some services or maybe there is some other damage... not sure though...
Hover this shutdown seemed different... total black screen and simply power down.
What I am concerned about... even on my main system ! is this:
RandomHash alledgedly uses some "memory algorithm" which is supposedly hard to run on a GPU and it's memory chips, so now instead it will run on CPU/MAIN RAM right ?! (The gpu option of the pascalminer is not to be used... ?! instead cpu option !)
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!! SO THE ISSUE/WARNING ALERT IS THIS: !!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
RandomHash will make your memory chips RUN HOT !!!!
!!! Probably/maybe much hotter than normal !!!
And at least on my hardware there is no way to check the MEMORY TEMPERATURE OF MAIN RAM ?!?!?!?!?!?!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
So as far as I am concerned this is a very bad and dangerous situation.
I can monitor CPU core temperatures fine with CPUID HWMonitor tool/software. I can monitor GPU cores with GPU-z and such.
But here is my point:
Monitoring the temperatures of memory chips is unheard of as far as I know ?!
My hardware is old though.
Can your hardware and software monitor your memory chip temperatures ?!?!??!?!?!??!???!?!!!!?!?!?!?
If so please backup any claims with screenshots as proof !!!!!

Note:
I have been through the experience of having a RAM memory chip develop 1 single bit error probably due to heat, static discharge can also not completely be ruled out.
This was a very scary experience which lead to file to file copy corruption and zip corruption and cd/dvd burning corruption at the time... very scary.
I would definetly not like to go through something like that again.
So this is a big worry right now.
Nobody really knows what kind of HEAT and STRESS RandomHash will cause on main RAM memory chips.
Perhaps this very shitty german laptop is a very fortunate thing to happen... without it... this potential issue may have remained hidden for some time... until much later... when better ventilated systems might also start showing damage because of this. Now the issue was immediately detected by this shitty german hp laptop with intel hardware/cpu in it.
I have used my current main system for 12 years and I am pretty confident it can handle all kinds of memory stress/loads cause god knows I have stressed the shit out of it with all kinds of softwares lol and test programs.
However RandomHash might be something totally different/something totally new that may tax RAM chips like never before ?! So I am slightly worried about this.
It seems to only use 1 or 2 MB of RAM or so from these chips (according to pip/documents, not evaluated via monitoring tools yet), but this specific section will probably become pretty damn hot !
Now imagine running this for 24 hours non-stop ?!?!?!?!?!?!?!??!?!?!
You may be risking damage to your RAM chip ! So consider yourself warned.
I hope to god that I am wrong... cause it would be cool if I was wrong... but this laptop shutting down might be a sign of things to come...
For your information: This laptop was used to run a pretty hot game: "Master of Orion"...
Hopefully the shutdown is not related to heat... but I am pretty damn sure it was... because the FANS started spinning up like crazy.
First miner: it was like ok... little bit of fan spin.
Second miner: wow... much more fan spin...
Third miner: fans going super load/max for a laptop... few seconds later... BAM laptop shuts down...
This was an i3 core laptop 2 real cores 2 logical cores.... so this thing has hyper threading... maybe it was a hyper threading bug but I don't think so... maybe the laptop has special overheat protection software or maybe it's just the CPU inside forcing the shutdown... or perhaps some motherboard sensors near memory chips shutting this thing down. Pretty sure it's heat related though. (So I don't know exactly what happened cause I don't know this fucking laptop that well lol... but it was pretty damn scary ! it rarely or almost never did this during master of orion... not that I can clearly remember... maybe one time or so... maybe two times... but then I shutdown many services... currently it has some services which may not be necessary but nothing to bad... before running the software the system was pretty idle... so I don't think these services are contributing to much to heat... though I could try and shut some down... I don't think it will matter measure... and the overheat/shutdown result will probably be the same. Perhaps because this enclosure is so small... the heat from the memory chips reaches cpu sensors... ofcourse I could be completely off the mark... and perhaps it's the CPU itself that is totally overheating... that could be and would be very funny as well... then intel's/hp products truely crap then again one might consider this some abnormal heat/load detection by advanced software and shutting it down out of precaution... though it more seems like some shitty overheat situation which is simply bad product design... your mileage may vary... very interested in hearing about any other systems shutting down because of overheat !

Here is my question for you:
"How the fuck are you going to measure your RAM chips temperatures ?!" Would love it if somebody could actually do this ? =D
Bye for now,
Skybuck.
