Perfect ... thank you.
The ROG protective cover over the m.2 slot (which I couldn't be bothered to take off to look properly) meant I couldn't see what was under there. Had I bothered taking it off (didn't have correct size screwdriver to hand) I would have been able to read the word 'remove' on the plastic film and see more clearly the likely purpose of what is indeed a thermal pad and also I would have been able to take it (plastic strip) off by lifting up gently rather than pulling sideways dragging part of the thermal pad with it !
Ah well .. live & learn ... thanks again
hmmmm... having taken it out, it clearly said 'remove' on it (couldnt see that while it was inserted!)
Next question ... the pale green soft gunk that it was attached to only partly came out with it. Do I reinsert the bit that came out or remove all of it ..or does it not matter so much?
the bios set fan speeds to a default. When I powered up and left it in idle the cpu went from 28 deg to 40 deg in about 10 mins so I tweaked the cpu fan profile. to 35% at idle (ramping to 50% at 40 deg then ramping to 100% at 60deg). Not seen it above 35deg since.
Wow ... thanks .. I hadn't realised how bad they are for stuff like gaming.
I guess for my purposes which is largely going to be drawing sets of circles and ellipses as data is generated it may not be so bad.... and it'll become obvious if it is.
Thanks for the comments so far.
That cpu and m/b look good. Am I right in thinking it's 4 threads per core ?
It seems to me it's almost all in the processing speed. I need to recalculate x,y,z position, velocity vectors and compound gravitational effects for each point mass (sun / planet) and then justoutput each position as a small /medium blob (scaled to uniform density input mass) to a screen in a time series. 3 stars and perhaps a dozen planets would be a min ...more nicer to allow for moons ..to make sure things don't mess up for possible real systems (there's a nearish, interesting triple star system hd131399, but it's unclear ..to me .. how many planets / moons / debris belts other than the massive planet that's been detected)
I'm proposing to write the code in fortran within windows (the only reason for that, probably quirky, decision is that I know fortran & it's compilers and operating systems like dos and windows but know nothing about C++ or linux). I also need to try to learn how to write code that works well with the cpu type (my previous fortran programming ran on a Cray so elegance in code was for show more than go.. I suspect I need to write for 'go' here)
I've no real idea about the balance between RAM and cpu speed ...I just suspect I need a fair bit of both.
Quite right, I need a case as well!
A refurb workstation is probably the best plan to get more speed per £ spent ...but understanding what a good current spec would be helps me a lot as a starting point.
Other uses would probably just be word processing, spreadsheets etc. No real need for internet access or gaming but no problem with having it connected online via a tethered phone (no broadband) (I play simple app games like fallout shelter, clash clans etc on an ipad)
I might later like to model an ant colony,.. so expandability might be a nice to have. Realistically though, I suspect that this couldn't be achieved on a simple home build machine as it would be 15+ parameters per 'ant' and a very large number of ants...they'd end up more like snails than ants!
