2gb per thread is the minimum people should use for planning. Also, if you want to run BURP (which uses an MT app), be advised that their largest tasks need up to 12gb. So I would set my RAM to be 12gb or 2gb/thread, whichever is larger.

??????? Yes it has modular connectors. For everything sans the main 24 pin power. No need to have that unplug.Quote:

Just for the record, though - I put 8GB DDR3 1600 in the DrPop rig, upgraded from 4GB last month, and it didn't make a lick of difference in how much RAM was "used" for anything. Still around 2.5GB or so...this is running Win7 64bit Ultimate, AMD X6 100T, 5870HD...crunching 24/7 all out...I don't even game on it anymore, LOL. :rolleyes:
It just sits there headless, crunching, and the extra RAM I shelled out for "just in case", well, it would appear that it didn't do squat. :p
Huh? More RAM doesn't make it go faster. Each project's apps need a different amount of RAM. Most projects use 250kb per task or less. But some use 1-2 gb per task. For example, TLP can use up to 1.2gb per task, RNA can use up to 2.5gb per task, and like I said, BURP can use up to 12gb per task (running only ine MT task at a time). It all depends on which projects you crunch. So yeah, if you want to limit yourself to less than all the projects, install less RAM. And yeah, all that RAM will usually be sitting idle for most projects. But RAM is dirt cheap, and I like being able to crunch ANY project.Quote:

Again, I agree that RAM is cheap now, but I was just trying to point out that in my limited experiment, there was no noticeable gain when going from 4 to 8GB. Now, in the future, it might serve me well, so I'm happy to have it "just because"... :D
Yep it won't stop using the swap file just because there's more memory. That would make sense, so it'll never happen. What i had to do is actually disable windows from using a swap file.Quote:

what do yall think for the MOBOs?
CPUs
a friend is trying to sell me these...what do yall think?
this is seti usa's baby your advice...my money hpoe all the questions dont annoy i just want my teams input!
That CPU and mobo are fine if you're gonna build 2 systems with that $6k. The single system i mentioned before would net you more credits/day though and use less electricity and take up less space and make less noise, put out less heat, etc. etc. :pQuote:

i think the quads would be more than enough what counts is price in my book! i have the q9450 and i do believe on ebay they are still going for over 300$ if he sells em to ya for half that jump on it id say. but as has been proved with the ps purchase do not jump first hear from at least 2 knowledgable people here. i say that because i jumped with out asking for advice and f-ed myself on a pos video card im now stuck with. man was i pissed! my fault 101%. but no you will never bother anyone here with questions bunch of computer and gaming geeks here bring it on!;):DQuote:

OK - I'll bite on the socket 775 stuff. It's old tech, uses a lot of electricity, but could be worth it. Those Intel quads can O/C good, and are pretty fast.
What can you get the CPUs for? What can you get the mobos for? That's the deal maker / breaker right now.
An AMD X6 1100T can easily keep up and/or beat one of those for $200. The i7 940 is only $270 and would be head and shoulders above those when O/Ced...
So it all comes down to the price - if it's good, then yeah. If not, then let's try to build you out the best bang for the buck.
Did you decide to go with 1 Mega Rig or 2?
Please make sure you pay a fair price for those Q9400 processors. If they are used/overclocked they may have stability issues above their rated clock speed.Quote:

we havent hashed out the price yet, me and this guy have been great friends since high school so its gonna be one of those kinda deals...im sure i wont have to pay to much. im wanna do two systems but ive seen some pretty good arguments for one mega! (JPM) se we shall see!
Yeah, JPM is the man on the mega machines. I like to read all the tech articles on Anandtech and Tom's hardware and stuff...but I just don't have time to get too deep into it these days.
If you want the BEST rig you could possibly buy...I'd go with whatever he throws out there! But, the HAF-X case is simply tops. Can't go wrong there. That will probably be my next case, when I finally have the $$$ to max out the HAF-932 I have. :D
My conclusion - I think after re-reading some of our posts here, I'd vote for a newer tech on the mobo and CPUs...as JPM showed it could be done all in one rig, more credits, and at a good power savings too.
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 :p 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...Quote:

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!b-(
Check out the WUProp results page for the RAM requirements by project and subproject and OS...Quote:

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 :)Quote:

If someone has 6gb per core more power to them but my recommendation is 2gb per core. You can't run BURP then you cant run BURP but dose the BURP credit justify the extra $150 per core? that's 500k credits a day on PG in video card or 400k a day on milkyway.Quote:

...and I think this point of view is relevant, because who really wants to run a crap paying project, and therefore let SIC kick our behinds that much faster anyway? :D;)**==
That was a cock-up on by the project *AND* on the BOINC client. BOINC is supposed to suspend tasks when it gets that bad, you know, the "waiting for memory" message. Even at 90% setting, it should have allowed only one to run at once if it needed 4.2gb.Quote:

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

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.
be cool bitches!
Hey jeep. how the build going? Any updates? I just ordered a new rig, nothing like what your looking at, but a nice one just the same.
