So being around for ages I heard that wcg's energy project is the most cpu intensive. I did rosetta, fah, and wcg, and my knowledge was right wcg made the cpu 5-6 degrees hotter than any other project. Fah was about 1-2 degrees coller than rosetta. But I did notice that it uses a couple megs of ram less than rosetta. Anyways my point being, the energy project doesnt save work units, so you have to keep your computer on, and I tried googling what max recommended ram usage would be but couldnt find anything. I know keeping a computer turned on for extremely to long without the ram to back it up will infact crash a computer. The question I dont know is what is a safe amount of ram usage to be considered before restart. I have the windows 7 cpu meter gadget always running on my desktop that monitors ram and cpu speed so it would be really simple for me to monitor.

You can safely leave your computer always on. If the temperature is within limits nothing will happen. Check your hard/disk from time to time. More damage is done to computer when you turn it off and on again. The windows cpu meter can eat up to 10% of your cpu core. Do not worry about your RAM. Free memory is wasted memory. I too noticed that 100% CPU usage by Rosetta is less than 100% by Primegrid. I haven't run much of clean energy WUs to notice that they don't checkpoint. WUs can crach, that hapens. Either disabe clean energy in WCG settings of live with it. Also I do not think this is the right forum to discuss WCG and CPU crunching, but you have far more posts so i belive you know what you are doing.

Windows 7, which your pc's have, is MUCH better at managing ram memory then previous version of Windows and the 'free' ram you see has very little to do with how much ram is 'available' to Windows 7. Win7 now uses ram as a variable sized cache grabbing and releasing memory as other programs need it or free it up. In some cases the bigger the cache the faster the pc, in some cases the bigger the cache the slower the pc, because it has too much to sort thru to find what it is looking for, Win7 is trying to balance that. BUT it IS still Windows so it has its limitations.

I have over 10 pc's running here at my house and never turn them off except for monthly backups, after which I only restart the pc, not a full shutdown and then restart. Obviously there are software upgrades that require a restart occasionally, but for the most part my pc's just run 24/7/365. Most of my pc's are Boinc only machines, so even the software upgrades are minimal. I have zero memory problems since upgrading to 64bit Win7, but most of my pc's do have 16gb of ram in them.

Yea I know its not gpu grid related, but I got like 30,000,000 gpu grid points on two accounts I can find, so I like coming here. Maybe not the most relevant forum for ram usage, but dropping knowledge never hurt anyone. Plus im an oscar winner so I think very highly of myself. hahaha peace and love people

Yea, Im not totally convinced leaving a computer on for a month at a time is for me, but at least it gives me some perspective. I do have only 12 gigs ram, and its not the greatest either which I have found makes a profound difference. But besides that I do look to upgrade to a possible 32 gigs in each computer. Right now I have a tech ticket open on my gigabyte mobo site about if my H97M-D3H will support possible 16 gig sticks, as well as I know it wont utilize the speed, but if I could install faster ram, possibly not stress the ram as much, plus I dont think they make 1600 mhz 16 gig sticks. But these days I am focusing on decking my computers out as I go instead of immediately building a new computer. I did want to say all my points were made on 570s, back when a 570 cost like 300 bucks, more power if you get more points tho. To infinity and beyond, as buzz light year says

Actually the CPU is responsible for handling the memory (there's no "north bridge" chip between the CPU and the RAM anymore).

as well as I know it wont utilize the speed, but if I could install faster ram, possibly not stress the ram as much,
Socket 1150 CPUs support 1600MHz, the "K" version CPUs could go faster than this, but then the CPU's memory controller need some extra voltage.

plus I dont think they make 1600 mhz 16 gig sticks.
You're right. Your MB (CPU) works with DDR3 memory, and there's no 16GB DDR3 modules.
To have 32GB you need 4pcs of 8GB modules, or a 4-channel 32GB memory kit, or 2pcs of 2-channel 16GB memory kit.

Aw rats on the 16 gig chip. I wanted that because while it might still work, the friggin button for my ram 1 slot broke off, so ya know, tryin to keep it all in one peice if possible. The voltage thing kinda confused me tho, I mean I have indeed tried overclocking my mobo, and it just doesnt do a very good job (tho I did have some success with oc'ing the turbo), plus I simply dont like to as any slowness I find on my system I immediately contribute to the overclock, if you catch my drift. That being said would faster ram still at least run on my motherboard without the overvoltage? Any recommendations or limits as in mhz roofs? Ram is exceedly cheap right now, you can get 8 gigs for 30 bucks. The current ram in my system went from 40 dollars for 4 gigs to 20 last month, but thats still to much as I dont think amazon specializes in computers. Its about time for a ram upgrade I would say. Thanks Zoltan your the best! I also like your format btw.

i got it, give me one second while I see how many volts my memory controller can take, if I can find it as technical jargon confuses me, alot of it changes and becomes useless with newer chips, plus this board I dont think was made for overclocking like asus would be.

While what im about to do is probably highly annoying to most, lol, including myself which is why I dont mess with it, theres only like 10 actual options available when overclocking my board. I am more leaneant with overclocking my memory, or possible memory controller, because if you have quality ram it will work alot more often than not, which is why I thought alot of my overclocks failed. But hold my beer and watch this:

The first and most apparent is the DRAM Voltage it is at 1.5 and goes up to 1.7, but I dont think this is what you mean, and I always stay away from it personally because I know old i7's probably first generation, you could actually damage the chip if you went past 1.5

The Integrated Memory Controller, this is what I think you mean, but its not all that clear because it says it controlls PCIe and L3 cache while making no mention of ram.

Before I simply list the other voltages, I will say that when overclocking I just put them to the max because they only went about .100 over what was set by the factory anyways, which was far under what alot of people were setting things such as vcore to. So here they are;

Cpu I/O Analog
Cpu I/O Digital
Cpu VRIN External Override
CPU Vcore
CPU Graphics voltage

and thats all folks! I know its a chore to overclock being I personally have to google what they all mean, but im just going for the ram and thats about it. So if you see the one that needs the voltage you can make it short and sweet. I know this is gpugrid, but rosetta was at like 72 percent ram usage within 4 hours of it being on. Dont think alot of people could really withstand that. One more question I would like to ask is that when I go in to overclock the cpu I can raise the gpu on the integrated graphics from 1200 all the way up to 4000 mhz... not really sure where to begin with a x4 boost but ya know if you know, or not whatever. Thanks, peace~~!

one second forgot to record memory controller voltage.


integrated memory controller only goes up .100 voltage, if you got the time I got the money. lol

Win7 now uses ram as a variable sized cache grabbing and releasing memory as other programs need it or free it up.

I am really pleased by this technological advancement, but it is nothing new. Linux had this capability since like version 1. http://www.linuxatemyram.com/
When data is read from disk, it is stored in unallocated memory (to avoid reding from disk in future). When program asks for more memory, least used buffer cache is discarded and allocated to the program.

However, there was a problem with memory management in older Windows, when the system would gradually 'forgot' about free memory. This problem also appeared in version of linux.

Well I guess its the 1600's for me. Probably my safest bet anyways. 16 gig at a time, I would do 12 this month and then buy something possibly more quality but ya know they cost the same, and time goes by so slowely for those who wait.

My laptop, for instance, has been running GPUGRID and Rosetta for a good 3 years straight. Running pretty hot too... (average around 85 depending on weather).
