1) Message boards : General discussion : New Build For PrimeGrid (Message 125461)
Posted 995 days ago by Profile Logo897Project donor
Hi all,

I'm trying to get a new build within the next year or so still. My focus will be an i7 9700k CPU for the project to replace or go alongside my 2600k! The GPU will be a basic 1060 3GB, as I need nothing fancy. Question though: Should I use 8 or 16 gigs of ram? Also, does anyone here have an 8th or 9th gen i7? How does it perform on this project compared to say my i7 2600k?

Thanks,

Logan

I've got a i7-9700K after my old i7-2600K died.
With so many years difference, their performance is obviously vastly different. Not only because the general higher GHz, processor cache, memory speed, but also because 2600K didn't support FMA3 instructions yet. The new ones do since few generations, of course, and that's a huge boost for LLR and Genefer subprojects.

However, you should note that thinking back I maybe would have gone for i7-8700K rather than the 9700K. The 9700K is surely somewhat more powerful, but a lot more hot and power-hungry. The pro-con ratio would rather be in favor of 8700K for me.


Thanks, Duke!

2x4GB is sufficient for a pure cruncher. It's what I have in many of my systems. I think even 4GB would be enough, but it is impossible to get dual channel as 2GB DDR4 modules don't exist, and you really want dual channel. 16GB is only required if you do really heavy workloads or play the latest modern games.



Ok thank you!

The ram quantity depends on what you will do with the system. Either way, make sure to get a dual channel kit at a higher speed without going silly on spending. Around 3000-3200 shouldn't hurt.

CPUs since Skylake haven't really changed much, so 6 through 9th gen are practically the same for LLR. Per core, per clock, they are significantly faster than 2600k. Haswell introduced FMA which gave a 50% boost over Sandy Bridge. Skylake gave further refinements which resulted in another 14% improvement over that, based on my testing. The problem is, ram bandwidth may limit on bigger tasks. Small tasks will make full use of the CPU easily. Bigger tasks can be helped by running multi-threaded but fast ram will be needed at some point.


Thank you for the information, I greatly appreciate it! I will most certainly take that info! This system I will only use for crunching and not gaming. I am just curious as to 8 or 16 gigs because if I only need 8 gigs of ram it will save me lots of money.

I happen to have an Nvidia Titan Xp star wars collectors edition coming and would like to dedicate this gpu to boinc. What are some tasks on primegrid you'd recommend for this gpu?


The sky is the limit with that card.
It can run everything PG offers. You can even use app_config to run more than one task at a time if you find that one task is not making 100% use of the card.


Awesome, thanks Keith!

Do you recommend I keep my CPU overclocked?

Also any way to get rid of the green leaf popping up in task manager? I see it suspends my tasks for a second on and off which is slowing me down.


In the Boinc Manager do you have it set to suspend crunching when the cpu usage is above 25%? If so that's the problem, most crunchers change that setting to NOT suspend at all so we crunch 24/7 but people who use their pc's for 'work' too can't always afford the slow downs.


Thanks, i fixed it!

Thank you all. I will take these down as notes and save it for future reference too.

If you're certain it is stable and don't mind the increased power (or lower power efficiency) I don't see a problem with that. Of course, usual risks with overclocking still apply.


Ah, does overclocking really help this project or nah?

Could be throttling the CPU, how are your temps? Could also be BOINC suspending work due to other CPU usage, in which case you can raise the percentage or kill off the other running processes.



My temps are fine but they just keep fluctuating since my usage is.
