Hello, Ive just bought an OVH dedicated server but am having some trouble finding out how to start using it with PIOsolver... Are there are tutorials, videos or posts anywhere in this thread that can help me?
Once you can access Windows with graphical interface using remote desktop it's easy (just copy your Pio folder there or start the updater there the same way you did on your home computer).
If you have trouble setting remote desktop interface we don't have tutorials for that but googling "how to use windows remote desktop with dedicated server" brings some tutorials (I am not going to link here but there are some step-by-step with pictures on first page of Google search results).

I found out that I can't run sims on BVB spots where ranges are very wide and I would put multiple bet sizings there as well.
I don't have enough memory (I have 8GB).
With 8GB you should be able to run trees with 2 sizes at most points but not bigger than that. Those trees are already quite big but somehow it became fashionable to run trees with a lot of sizes, I am not sure if that's the best way as you need to wait a lot for solutions and there isn't much added value from having a lot of sizings available in my view.

So I'm thinking that do I upgrade my PC to DDR4 setup, or do I buy more DDR3 ram?
RAM speed isn't a bottleneck for Pio so if you can get away with adding more DDR3 RAM (you need empty slots on your motherboard) then that's the best way as DDR3 is cheaper.

Does GPU have big effect on piosolver?
It has 0 effect and it will stay that way for foreseeable future.

My CPU is Intel i5 2500k. Is this still a very good processor for running piosolver?
It's decent but you can easily get 2x to 3x speed-up with modern fast CPU (like hexa core i7 or 1700/1800 Ryzen).
You can run a benchmark, like here:

and see what's the time is. Ryzen 1700 gets sub 5s one. Something like 5820k gets around 6s not overclock but can be overclocked to get much better results.

Does piosolver utilize multiple cores well?
Yes, pro version uses up to 12 threads in this version and it will be 16 in the next one. It means it will use all the cores in home CPUs.

Is there difference between 4, 6 and 8 cores?
Yes - the more the better.

so I'm not hesitant to make a huge computer upgrade right now.
So tl;dr: Is Intel i5 2500k "just good enough" for pio?
The problem is that it's likely not the best time to upgrade. It looks like Intel vs AMD competition is back again and it's likely there will significant price adjustment as well as some new powerful CPUs in the next 1-2 years. I wouldn't upgrade from 2500k right now as it's a big investment for maybe 2.5x speed-up while it's likely you can get more for less in 1-2 years.
