Looking at doubling from 8GB to 16GB of RAM

With two more sticks of this stuff:

http://www.newegg.com/Product/Produc...82E16820233147

Price is unbelievable. I have something specific in mind (specialized RAM disk, since I always run use sleep mode instead of rebooting). However, I'm running my 8GB of this exact RAM in 8-8-8-24-1T timings without a single hiccup. Will adding two more sticks affect my ability to run relatively tight timings? I am not overclocking it, running pretty much stock.

I don't think it really matters that much but I'd like to find out more about what others' experience is with the Itnel IMC on Sandy Bridge running 4x4GB DIMMs.

My understainding is that if you combine two separate kits, even if they are the same, they could still cause a problem. It's not guaranteed, but its not a common problem because lots of people buy two kits. But because they are two separate kits, they haven't been tested in factory together. But since they are the exact same RAM, I can't forsee any issues.

that's not really much of an issue these days. unless you have something that is triple or quad channel and you mix kits for the same channel. if it's just dual channel and you're fill both sets, the memory will just take the speed of the slowest kit.

i run 4x4. i set half of my memory to cache with supercache to limit the random writes on my ssds. 🙂

A very good idea - I wish SuperCache didn't cost $79, though. My free solution was to create a RAM drive and direct windows and internet temp files to that location to limit the number of needless writes.
 
Pretty clever idea. There seems to be a number of free RAM disk programs out there. I have another thing in mind, which involves using Romex Fancycache, which is a data caching scheme to leverage additional RAM In your system for caching for volumes and disks. Evidently, this setup can really boost your performance. The guy who told me about this (In this thread: http://forums.anandtech.com/showthread.php?t=2203530) shows over double the normal SSD performance.

Something to think about. next paycheck, I'm getting the RAM and this software. This is evidently also a good way to reduce wear on your SSD, as noted above.
 
Why are you guys caching random writes to RAM? SSDS are incredibly durable and all evidence points to their lasting much longer than you can possibly write to them.
 
Windows will use RAM to cache your hard drives by default. It will only evict if you run a process that needs the RAM. Now admittedly its write cache is normally relatively small, but its also much safer not to have a RAM cache that could be lost when the machine looses power with a lot of writes still pending. Therefore only read caches are safe and Windows will happily consume all your RAM making one.
 
SB's memory controller is stellar. You shouldn't have any trouble with 4 sticks @1600/1T. I run 1866/2T (1T wasn't 100% stable) only because I kind of got lazy and did not bother with any of the subtimings other than the "big 3" (tRC-tRCD-tRP). I am positive that even 2133/1T shouldn't be an issue with a quality board and some tweaking.

Most of the time it comes down to the board's BIOS and how it defaults/gets around the sticks' SPD, depending on which how much time you need to devote. Considering the popularity of DDR3-1600 I would expect the board will simply get things done automatically after a power cycle or two.
 
RAM has really gone up in price.

I noticed a nice boost going from 4gb to 12gb, but I'm not sure I would notice much going from 8gb to 16gb. More memory is always nice, though, and can be used in interesting ways.
 
Yeah, I bought my ram when it was really cheap a few months back. Went with 16GB due to how cheap it was. I have been thinking of doing something like a ram disk because I too have seen a decent amount of writes to my SSD already. I moved my page file off it and onto regular disks.

Yes, I find it hilarious that after all the money people spend on the SSDs they buy, they get home and spend even more time figuring out how to AVOID using them. lol

I'm not sure who to blame, but if the users are right, it says a lot about the current state of flash technology, on the other hand, if the manufacturer's SSDs specs are right, it says a lot about the users.

No, looking at data caching and not at isolating the SSD from random writes, which in any case can't be done. I just want a cheap boost in performance (not that it's really necessary, I just want to see how it works out based on reports from a fellow user).

Also, if your system is set up correctly, having pending writes in RAM getting blown away shouldn't ever be an issue. A data caching scheme would work for me since I use sleep mode 95% of the time and the rest of the time I just do a standard shutdown, which automatically clears any pending writes. Since I can do it, and it may yield a significant performance benefit, why not?
