Upgrading RAM

I'm looking to upgrade my RAM on my build. I currently only have 2GB of RAM and am looking to get at least 4GB more.

My question is, what type of ram do I have to get?

I currently have Mushkin 240-Pin DDR3 1333 (PC3 10666). I know I need to get more 240-pin DDR3 RAM but I am unsure of the rest.

What do you guys suggest I get for RAM and what type to I need?
 
Well, you'll want to keep it the same.

Basically, keep the speed the same, and try to keep the timing close.
If you're lost already, basically look for DDR3 1333 RAM. Some sites like newegg post the timing of the RAM, which you could look up with the particular model of what you have already, then match or get close to accordingly.

Speed doesn't really matter too much either. You will simply be throttles by the speed of the lowest stick(s). For example if you got 1000mhz ddr3 your current sticks would be throttled to 1000mhz as well. If you got 2000mhz sticks those new 2000mhz sticks would be throttled to 1333 as well. You don't really want to shoot for this, but sometimes there are some killer deals to be had, so it wouldn't be detrimental to not perfectly match these speeds.

You have to make sure of two things first.
1. Can your motherboard support more RAM?
2. Are you running a 32 or 64-bit OS? 32-bit can only address 3.5 GB RAM at the most, 64-bit can support a whole lot (I forget the exact amount right now)

If you don't know if your motherboard can support more RAM or not, go to RAM Memory Upgrade: Dell, Mac, Apple, HP, Compaq. USB drives, flash cards, SSD at Crucial.com and click on "Scan My System" Install the little program and run it. It will tell you how much RAM you have installed, what kind, how much your motherboard can support, and give you some prices on RAM that they offer. (you don't have to buy from them)

A lot of times sticking 4GB in a 32 bit OS will cause instability, boot problems, and at the end of the day he is right ^^^ you still only address 3.5 GB. As for 64 bit windows the limits are....

Windows 7 x64
7 Home Basic 64-bit: 8 GB
7 Home Premium 64-bit: 16 GB
7 64-bit Professional, Enterprise, and Ultimate: 192 GB


Windows Vista x64
Vista Basic 64-bit: 8 GB
Vista Home Premium 64-bit: 16 GB
Vista Business/Enterprise/Ultimate 64-bit: 128+ GB

I built this computer less than a year ago. I purchased a low amount of RAM with plans to upgrade later.Looks like I'll just get whatever I can get a good deal on that has the same speeds, or higher, as my current RAM. I'm waiting for "cyber monday" hoping that newegg withh have some good deals. I'll probably end up getting 6GB or 4GB.Since I'll have more RAM than can be utilized by my 32-bit Windows 7, should I upgrade to x64? I have the disc handy.

yeah the gpu and cpu combo doesnt matter...amd claims that using all their parts will increase your performance......thats mainly marketing bs. get the best bang for the buck always. atm i think the 460 is the best value and it kicks the shit out of the 5770(i own one). but the 460 is newer thats just how tech goes. and it depends on your price range.

one other note thats worth mentioning. i tend to lean towards nvidia when it comes to cards. it really depends on whats goin at the time i want to upgrade though. hence me going with the 5770. but the reason i lean towards nvidia? drivers....dont really want to get on a rant but nvidia is and has been for a long time better than ati with their drivers. amd has gotten better but its still not comparable. .02

Just so you know, you can't just throw a 64bit disc in and install it. You need to have a 64-bit processor as well.

Are there any non-64bit processors that actually support DDR3?


Hmmm. The X2 has both DDR2 and DDR3 memory controllers. What mobo are you using, that will make it a bit clearer on what your options are as well.

OK, that mobo has 4 slots, capable of 16 GB total. So, keeping your current 2 GB and adding 4 GB to make it six is doable, but it may be in your best interest (particularly since you'll need to go with a 64bit OS anyway) to look at matching 4 sticks of 2 GB each, for a total of 4*2 = 8 GB of RAM.

The specs also suggest that the mobo only handles RAM with the following speeds: DDR3 1666(O.C.) /1333/1066 - so that will be the key. Anything faster and it will most likely be scaled down to 1666 or 1333, unless you're an avid overclocker and and push the limits of your mobo.
