Games like BF3 etc need 8GB of RAM in your PC for full smoothness. Whether the app directly uses that much or not, and whether the FPS are affected or not, 4GB with BF3 = stuttering. 6GB is better. But 8 GB is perfect.

Given that we already need 8GB, games released in the next 8-15 months will need 16GB for the same experience, some games at least: ex: Max Payne 3 which already recommends 16GB RAM.

Besides, that RAM is literally free compared to the other parts and helps multitask etc.

Do you have numbers for this?

Do you know what 'literally' means?

Because at $30 for another 8GB of DDR3-1600 is so cheap, I'd rather just get it since i derive utility from filling having my equipment use its full potential, and my mobo with 2 slots not filled is not at its full potential.

Can I run ...BF3 in my computer... my specs>>?
Pentium 4, 3.00 ghz
4 Gb ram
Sapphire HD 6750 2 GB
Windows 7 Ultimate 64 bit

Depends on the resolution. My stepson has a 1045T, 4gb, xfx 5770 and w7 32bit. He plays at 1280*1024 and runs it fine on high settings at that res. Prob want to start a new thread or google it tho.

Edit: I'm sure all the cores help as well though.

This is the weakest argument going around.

Where do you draw the line? You could spend another $30 for each and every PC component.. but that doesn't mean you should.

Anyway, the "enthusiasts" buy absurd amounts of computing power, like 16gb to 32gb of ram because they want to give the impression to others that they are involved in some sort of badass, elite, exclusive computer usage. :whiste: .. That, or they've been successfully convinced to over-buy on as many parts as possible, thanks to sites like this one where they perpetuate wildly unrealistic ideas of how much computing power one requires.

I kind of like being able to play a game, have a few news articles or tech reviews open in my favorite web browser that I can read on down time in the game ('cause someone went AFK), another couple of tabs for email or <insert chat or other social website here>, ventrilo/skype to chat with friends, some kind of video encoder running at full blast on insane settings (and still finish encoding a 2hr source in less than 2hrs), all while not running a page file, and all while having zero fear of cache thrashing or other misc slow downs due to a lack of RAM, and all while having free reign of opening a second client of the same game to dual box someone's toon for a few mins or being able to open most any other application, or several, for that matter. Then there's always F@H that once up and running, most people don't shut off, even while gaming, or encoding a video.

Oh, and some people buy the amounts of RAM they do because it's cheap... and why not?

I really do wonder about just how much computing power you people think you need.. you are literally talking about a THIRD OF A GIG of ram to keep a browser up with dozens of tabs opened in the background.. yet you are using this usage to justify over 50x that amount of RAM?? ..

I think thelastjuju hit it on the head. The most likely reasons are a combination of dirt-cheap RAM prices + peer pressure/e-peen, resulting in a solution looking for a problem/use-case.

Of course, a decent percentage of the members of this forum build workstations to...well...do work. However, because the OP specified gaming in his first post, I'd say that even 8 GB is overkill for the overwhelming majority of gaming scenarios. I had 12 GB in my old C2Q workstation, and the only time I ever saw RAM usage get anywhere close to the double-digit mark was with two VMs open, some intricate Illustrator files sitting in the background, and taking a break from work while playing a game at 2560x1600. This happened maybe twice, ever. I therefore am sitting at 8 GB on my new i5 workstation because I have no idea why I ever thought I needed to run two VMs concurrently, much less assign them quantities of RAM in excess of what they actually required-- except that I could.

But hey, if you want to load up on RAM and keep prices low, by all means do so. If and when I need to add more, I certainly won't complain about the lower prices.

Win 7 "reserves" memory even if it's not using it. Do not look at your RAM usage using the usual tools. These reports of "zomg, Win 7 is using 99% of my RAM" have been around since the launch of Win 7, yet people are still jumping to the same conclusion even in 2012.

Doesn't happen when u have 32gb installed. Win7 shows around 16-20gb free.

This is only if it's not actually in use, and just reserved. If it is being used, then you get all manner of error messages and slowdowns, and then you get a spontaneous reboot. Trust me. I've tried this.

Yes, sometimes Windows 7 does need more; I have run into those problems myself with programs w/ memory leaks and leaving on my PC for many days or weeks at a time. But it reserves a few GBs for itself even when nothing is going on... that's what I'm getting at.

Games don't have to be "modern" in the sense most people are thinking about to max out memory. The one game I actually run out of memory the most is actually Minecraft--because I use 256x texture packs and Java itself is a memory hog. I'd feel comfortable running VMs if I had more memory, too. I could get another 4GB for my machine but DDR2 just costs too much. My next build circa Haswell will have 8-16GB.

You guys are all talking about games. For that all you need is 4GB to 6GB of RAM.

I use Sonar X1 and that is where even 16GB is no where enough for my projects.

If I preload all samples and what not, sorta like a template I would neeed at least 64GB. For now I cant do a template like that cuz I have gotten the out of memory pop up on some of my projects,,, anyhow a DAW or Video Editor will actually use up that 16GB , which is not enough for me. 64GB RAM sounds juicy! Hopefully Haswell will allow for 64GB on their desktop mobo.. thx gl,






thats me using 7GB of RAM after a reboot and only loading BF3

and I have textures in game set to med or low since I shoot for 120FPS@1080P or 60fps@1080p eyefinity

I'm going to ask it again in this thread even though someone else already asked it: Do you know what literally means?

I'm not literally talking about a THIRD OF A GIG to justify any amount of RAM. This is a simple case of selective reading. Try again.

What I said, is that it's nice to be able to play a game, have tabs in a browser open, have vent/skype open, have a video encoder open and active, have F@H up and running (-bigadv), not use a pagefile, and still have plenty of room to open a second client of the same game, an entirely different game, or other programs entirely.

Another consideration, is RAM channels. If I wanted to take advantage of quad channel RAM *and* run sanely minimalist for my hardware, it would be 4 sticks of 2GBs each leaving me at 8GBs. The way I use hardware, it'd be cutting short in several usage scenarios, though typically never by more than 2 or 3GBs. That means the easiest option available to me, is really 4 sticks of 4GB RAM.

I'm sorry if all of you 16GB no sayers are offended, but don't you think you need to open your eyes a bit? A very low percentage of people with quad channel capability are going to run 4 x 1GB. A much larger handful will run 4 x 2GB, and then there's another handful yet that just barely push passed 10GB requirement and will run 16GB because it's the easiest solution.

If you have to ask then you probably don’t need it. A lot of it is for e-peen and the fact that prices are dirt cheap, but there are some cases where it’s useful (e.g. running multiple VMs, working with huge image and video files, working with large databases, etc).

It can also be helpful if you do a lot of I/O because the OS can allocate a bigger disk cache and keep more data in the RAM.

with ecc you can leverage chipkill and multi-bit correction. not sure if I7 works the same as xeon but if you only use 1 dimm out of 3 (4 for newer xeon) you feeding the cpu 33% (25%) of total bandwidth .
Adding a second row of dimms (not exceeding rank limits, RDIMMS) allows further interleaving. 90% of the gain from core to nehalem/westmere/etc is RAM bandwidth.

More cache - less i/o - with SSD's having less chips and smaller size nm - you get less P/E cycles - anything you can do to reduce paging/writes will prolong your investment.

fact is ram is stupid cheap - drives are not - ram (ECC) is very reliable - drives are not.

RAM > SSD > SAS > SATA = given - we can agree. I found zero speed increase going from 32gb to 64gb for SQL server but disk i/o dropped 10 fold (in a vm). log writes obviously are what they are but now they have 2-4GB ram cache with up to 512gb+ flash cache to reduce writes/reads to (inflated) expensive drives.

24gb of ram (cheap) in my mac pro - i can virtualize everything in the house including several osx and just use high speed wifi to RDP and browse, develop(wired), etc.

remoteFX and other remote gpu will allow us to have a core servers doing all the work pushing 3D/2D graphics to low power dumb terminals (TV SET,old-azz laptop) extending their usefulness greatly.

The cloud can live in your basement pretty cheap.

Hmm, well, I'm glad I went with 16GB for my main rig. I do DC (BOINC), and there is one project that has WUs with high RAM usage (8GB+). So on my old machine with only 8GB physical total RAM, it was swapping to my SSD, thus wearing it out faster.

However, I was only running that project for a few months on the new machine, and haven't lately. (Project seems dead now.)

So now my 16GB of RAM is basically doing nothing special, and I could get along with 4-8GB for certain. But it's nice having it, even if I don't need it right this moment.

I've been noticing slow downs and heavy pagefile usage with BF3 with 6GB. I play with a 6990 and Eyefinity at 5760x1080 res. I heard that Crossfire and Eyefinity actually need more system ram for smoother gameplay in BF3 so I went ahead and ordered a 12GB kit from the Egg for $70. I'm going to see if it has any effect whatsoever

32 Bit OS or memory controllers capped us at 4GB for a long time, RAM is cheap, and it makes me hard.


















Core. Hard core.

Whew!, this thread wore me out. Remobz, your comments are my thoughts exactly. And I also would think that for most that have more than 8 GB the next logical step would be to SSD to better get "more bang for the buck" so to speak.
