Hi, if i have 32gb of ram, computer will use all of 32gb to speed up tasks and system or only use the ram that say on task manager?

This video say that games use let say 8GB ram but all of the ram in the computer is used to speed up system, so a computer with 64gb ram have more performance in games that a computer with 32gb ram even system use only 8gb ram in task manager...

You are right, i use cpuid and say my memory is running at 799,9Mhz...

Your ram will show 800(because of the double transfer[rising/falling] nature of DDR) no matter how many sticks you have. You should see an indicator for Dual or Single channel on the same page in cpu-z(right top I believe)

So its FREE and not available? strange
Windows has learned overtime what you like to use. It may still even hold some information from programs you have recently closed in case you want to open then up again. The system is rather adaptive.

BTW, I did a check on mine and it said I had about 10 to 12 gb free...this wasn't ingame though. Would 4gb be a decent starting point for a Ramdisc? If so, is there a decent guide of how to set it up somewhere? Many thanks in advance!

It say dual. So my computer is using 1600mhz with 3x8GB Ram? Should be using only 800mhz because of the 3 sticks?

It says 15GB in cache, free only have 3gb

Can you say me if my Ram is working at 1600mhz by the screenshot? It says 800mhz on frequency...

yea its running at 800 MHz aka 1600 if in full dual channel mode. you will get more speed if you take one stick out and verify that 16 gb are in dual channel mode.

on a side note those timings are really high for 1600 MHz ram. I would expect 9.9.9.27 or lower

cashing is more difficult than I think you are ready for. just setup your computer with dual channel and be happy with that. 1600 MHz is much better than the 800 your running at now

always remember that when it comes to ram over 8 gb in windows 7,8,or 10. speed is of more importance than size unless you are video rendering.

that is the one rule

I believe that your first pic showing 799 MHz is showing effective "real" speed of your ram

Just remove the 3 stick and stay with 2 sticks on slot 1 and 2 but now the information on Cpuid is the same with 32GB expect that now it say Single instead of dual...

It's running at DDR3-1600. The clock rate and data rate are independent of the number of channels.

It says quite clearly in the first image that it is configured in dual-channel, but it does not say what dual-channel mode.

Lots has been said again.

Chances are it is some kind of flex mode(I think that was the Intel term for it) for dual channel(last 8 gigabytes will perform like single channel with the first 16 performing as dual channel).

The timings are not that abnormal because 8 gigabyte sticks tend to have slower timings than 4 gigabyte sticks unless you want to pay much more.

As I have said already, dual vs single channel does effect bandwidth, but NOT clock speed.

Outside of benchmarks in day to day use, I do not think you will notice much unless you fill all your memory(and remember even slower memory is much faster than a hard drive and even ssd).

You can get some performance numbers here.

Setup is just like another drive once installed and configured you just either install programs or redirect program writes to it the same way you do in a multi drive system. Please take care redirecting any OS critical software to a ramdrive because that may cause all kinds of issues.

It would be best to start a thread about setting up a ramdrive. More users may chime in and give you more informaion.

I am now with 16GB. Now i put (8 but dram frequency saysGB stick memory in slot 1 and slot 3 and left emprty slot 2 and 4.
Now it says again dual channel but dram frequency still say 799 and max bandwitch say the same 800mhz...
Say exactly the sma enumbers i have with 3 sticks... So what the point of having only 16GB instead of 32 if the numbers are the same?

800Mhz is correct for DDR3-1600. This is what you're running. Everything is fine. The Kingston HyperX Beast DIMMs that you have installed use a native DDR3-1600G profile straight from the manufacturer (no XMP nonsense) which makes them very plug and play friendly.

as nukemaster said intel has some weird half dual channel half single channel thing where it runs 16 gb in dual mode and when It needs the rest of the ram it goes into single channel mode to get the rest of it.

ive always considered 1600 MHz ram kinda bottom end when it comes to ddr3 ram I recently bought 2400 MHz ram for an A10 apu system and ddr4 speeds can go well over 3000 MHz when building computers for a client I always use high bandwidth ram and look for low timings.

most motherboards will have 4 ram DIMMS they will be labeled in order 1,3,2,4. in order to get dual channel you should have one open space between ram dims. this would put the sticks in slots 1 and 2 or in 3 and 4 as nukemaster was describing

Someone said that a 2100 with greater timings was slower than a 1600 with lower timings... Its not only the mhz that counts
Dont you think that 12 is little slower besides 2666mhz?

timings refer to the time it takes from when you request data to when it regisers that you want it. lower timing will result in a faster response time. once the ram responds, it is upto the speed (1600 MHz) to transfer the data to cpu and HDD and gpu as needed by the task at hand. while the lower timings will feel snapper in simple small tasks the 2660 will be faster for large tasks and by a large margin. go with the higher clock speed (2660 MHz)

this is why I usually use 4 gb sticks with high speeds. 2400 MHz with 12,12,12 timings will be really fast in both the response time and in the transfer period of the ram. if you populate all 4 dims you will have 16 gb of ddr3 ram and it will be at lower timings than 8 gb sticks (typically) and a higher speed ( typically) or at least for the price.

the best of both worlds would be to get 2666 ram and OC the timings from its stock 12,12,12 to 11,11,11.
