baddest build...6k budget

[John P. Myers]

Hate to bump this thread, but i'd just like to say i got my ass handed to me lol

We were discussing the amount of memory needed in a system to comfortably run pretty much any project you wanted, with no limitations. I personally have a quad core with 8GB RAM. And it crashed. Why? Only 2 cores were running the tiny little Renderfarm project, which demanded 4.2GB from each core at the same time. Unfortunately, i allowed BOINC to use 90% of RAM, even while the computer was in use. This combo didn't work too well I've since dropped it down to 70%.

Looks like if you want to be able to crunch any and all projects at will, you'll need to go with 6GB RAM/core. 32GB on a 6 core would most likely work as well.

Yeah - I have since disabled ORE from running on my home machine. After crashing that hard, I'm done with it for the time being. This is a new issue, though...

Where would one find the ram requirements for the projects?

Right now there is a sweet spot for RAM on projects...

It is dictated not by what each cpu core can handle...

Instead it is the simple fact that 1600Mhz DDR3 RAM comes in either 2Gb or 4Gb chips. The 4Gb chips cost over $70 a piece while 2Gb chips cost just $30, or less.

You should buy 1600Mhz DDR3 because newer generations of cpus from Intel and AMD will support these speeds. The memory can be reused in multiple machines as a result or even sold two years from now due to its broad compatibility.

I am running into this problem with my AMD G34 that has 16 memory slots... trust me, my wallet cannot handle $70 x 16 and still buy a nice NVIDIA GTX 590!

Check out the WUProp results page for the RAM requirements by project and subproject and OS...

Thanks? Not sure if that's a compliment or insult...

one out of 1200 useful? take it any way you want

no there has been a lot of useful stuff, this one is just the "most" useful.

Seems those memory reults are an average, meaning it could take more, or less, depending on which WU you're handed. ORE is stating about 2GB/core average. I'll agree with that since it was until 2 days ago i began having memory problems. Also, BURP is listed as 5GB across all cores, but Zombie67 knows it can be far more than this. Just keep an eye on things

I am in a cranky mood. And this is NOT pointed at *anyone* in particular.

Er, we are *all* running this project for the *free credits*, right? So we all already know about this project, and what it does, right? This should not be new news to anyone on the team.

Edit: Also, to avoid confusion, heartbreak ,and wasted money, we should be talking about gb/thread, not gb/core. For AMD, it is still 1-1, so there is no harm in calling a core a thread. But for intel, it is a different situation. Especially now that we are in now the second generation of modern Intel chips with HT. And no end in sight. As far as BOINC is concerned, it counts threads, not cores. So we really need to plan RAM per thread, not core, so there is no confusion, regardless of CPU.
