for best value ram: http://www.overclock.net/t/1326571/ram-kit-value
for best performance: http://www.overclock.net/t/1326564/ram-kit-performance
and look at best performance big voting on the corsair and big diference between all, also G skill did not make it in the poll for the performance
so I am a bit confused.
Another thing regarding the ram cache for the raid arrays you use, now I don't have all hdds for the raid arrays I want to make, I was wondering if I can still use the ram cache for ahci ssd/hdd as buffer, same thing like u have in raid but only in ahci, can it work? lets say I have 4 gb to spare 2gb for 1ssd and 2gb for 1hdd something like that.
I have 3 different sets of G.Skill 64GB @2400 Ram. The first is a set of TridentX which are actually dual core optimized but work no problems on my RIVE M/B. The second set is the RipjawsX @ 2400 and the RipjawsZ @ 2400. I am using the ASRock X79 E11 M/B and I was having problems getting it to run at speed with 2400 Ram. It would see it and I could save it at that speed in the bios but when I went back into the bios it always defaulted back to 2133. It is very unusual for G.Skill Ram and I found out that when I put the ram in my RIVE M/B it worked fine so I took screen shots of the settings that were on that board. I did the same for both sets of Ripjaws. I then put the ram back into the ASRock M/B and manually set the ram to the screen shot settings. They both work perfectly @2400 now. I have used the same ram on many builds for other people and this was the first time that this happened. It has something to do specifically with the ASRock board only. I have checked out all the timings on the Platinums vs G.Skill and they are the same. The only difference is the price. My RipjawsZ set cost me roughly $750 while the same Platinums cost $1200.00. I have never had any G.Skill ram modules fail. I use them mainly because they are one of the very few that offer 2400+ in 8GB sticks. Patriot offers maximum 2133 and they have 1 set that is dual channel only @ 2400. Crucial offers 1866 only and most of them are 4GB sticks. Any 8GB sticks are dual channel optimized. You can use dual channel in your system but there may be a little degradation in speed when tested. Only Corsair and G.Skill offer Quad channel kits @2400+. Corsair has the Brand name notoriety and people just flock to it because it may be more widely available depending on where you live. The name has been around much longer than G.Skill and they offer more than just Ram. They have cornered the closed waterblock cooling units market and some other markets as well. That makes them more popular while G.Skill basically only sells ram modules. I would gladly buy G.Skill rather than the overpriced Corsair ram any day.Very Important about SSD caching
Never cache your SSD or Main C:\ drive. Windows updates will become corrupted when installing using a cache in that way. Only cache your other drives. Put the largest amount of cache on your linked drive. It will speed up the file transfers between the 2. This is the ultimate way to use it. Your SSD can handle things on it's own very fast but the boost needs to be on the linked drive foremost. That way when you save large files it will be on the linked drive and be very quick to finish. On occasion I have moved my video folder which contains 500GB of material. Your cache will only be quick until the set size is populated then it slows right down to actual drive speed for the rest. So if you create a 32GB cache on the linked drive then files up to 32GB will move quickly and be done as fast as the SSD can transfer it. Your ram is 10x faster than your SSD so that will be the speed value being set. Your SSD can read approx @ 500MB/s give or take depending on which SSD you have. Your ram can handle 10x that speed. Look at the largest file you have and think that you want to move 10 of them at the same time. That should be you cache size for the linked drive. Most 1080P videos are 4GB unless you are storing complete 2 hour long BluRay movies then they will be much bigger. You can change the cache size any time you want for any drive. If you want to move a large file from 1 HDD to another HDD then make the cache equal size on both HDD's for the transfer. It will happen quickly but remember that it is running in the background at normal drive speed so don't shut your computer off while it's still moving the file. You will lose whatever didn't get transferred as soon as the ram shuts down.
You can run a Ram Cache on any drive or Array that you want. You will need software to accomplish it though. I am using SuperCache5 software. I have run some extensive tests using it to see how it works and what the advantages are. When you load the Supercache program you can create multiple caches for different drives. It all comes down to where to use the cache for the best advantage and how big you make it. I have a drive that is fully linked to my SSD drive. Everything I download or save and put in my "Documents, Pictures, Videos, Downloads, and Desktop
" folders all actually reside on my HDD not on my SSD. SDD space is too valuable to waste on storage of any kind. There are ways to maximize your SSD so that you aren't wasting space on your SSD. First of all disable hiberfil.sys. This is a file that is equal in size to your ram. It's only function is to store whatever resides in your ran when you system hibernates. This function should be disabled to make your SSD last longer. To do this open the CMD prompt window with administrator's rights. Type in "cd\" hit enter. Then type in " powercfg -h off " this will only work running as administrator. Second thing I do is modify the recycle bin size. Right click on recycle bin and make your SSD or C: drive 4096MB and change your linked drive by adding what you took off the C: drive to it. I use the same principle when I change the page file size. For quicker access I usually right click on the main screen and go to personalize. I look for desktop icons and add the user folder to the desktop. You can add others if you want but for this exercise we'll just stick to User Folder. Apply and ok until your back on your desktop. You will now see a folder which has all your saved file options in it. Double click on it to see all the folders. There are various ways to do this. When I build a system for a family I will purposely change the drive letter of the drive I want to link to the letter Z:. You can do this in drive manager. The reason why I pick Z is because every time you plug in another drive or flash drive Windows will automatically designate a drive letter for it. Picking Z means that you need to have 24 drives installed before it reaches Z so that means Windows will never change it and it is easy to find and locate. Most of the computers I build are for family use and everyone has access to it. To prevent the kids from playing with folders they shouldn't touch I create a folder named C on the Z: drive. I then change the folder icon to a red exclamation mark. This does not look like any normal folder and they won't recognize that it is a folder at all. I then go back to my user folder and when I right click on i.e. Documents scroll down to properties. There will be a box with the folder name. I copy the text and then look for the location tab. Click on Move. When the box come up scroll down the left window pane and find drive Z: click on Z and then double click on the exclamation mark folder. Once inside create a new folder and when it comes up paste what you copied into the folder name. Click on the page beside it so that the folder is created with that name in it. click once on the folder to highlight it and then save it. It will move the Documents folder there. A box will pop up telling you that there are files that you are attempting to move within the folder. Say yes or ok and let those files move to the new location. Do the same process for every folder I listed above in red.
