Understanding RAM characteristics

Hey Ginko, I was hoping you could help me out with this one:
What's the diff between say, 4gb of 667 or 800Mhz ram and 2gb of 1066 or 1200? Is less Ram at high speed a better option? I guess it goes without saying that 4gb at 1200Mhz would be ideal, but I dont think I can afford that.
Mobo is ASUS p5q se/r

Regardless of the speed RAM is nothing more then a container for running programs. Hence the more ram you have the more programs you can run concurrently (at the same time)

Speed has to do with how fast the running programs can be put into and accessed within the RAM.

Hope this helps

I have a M2A-MVP motherboard and I am trying to use more than 4GB of ram on Windows 7 64Bit but when I install more than 4GB of ram I get a blue screen at start up then it resets but in safe mode it shows...


how many ram modules are you trying to use and what sizes always keep the largest ram closest to the cpu central processing unit and it might be a compatability problem always try to keep using the same type of ram
hope this helps

Ram again


Go to your google search bar and type in SIW, download and run it. In the left hand column, scroll down to the hardware section and click on memory. It will tell you how much you have and how much your motherboard is capable of handling.
Some boards like my Dell 8400 will take 4GB and use it all but the motherboard only recognizes 3GB, so if your unsure you might be able to go to the computer manufacturer website, go to support, type in the info for the computer you have and they should tell you what that board is capable of.
Hope this helps, good luck

4GB memory not being recognized


To recognize more than 3.5GB RAM you must use a 64 bit operating system
ordinary 32 bit O/S only recognize max of 3.25 to 3.5GB ram

Purchasing RAM


DDR3 modules can transfer data at the effective clock rate of 800–1600 MHz using both rising and falling edges of a 400–800 MHz I/O clock. In comparison, DDR2's current range of effective data transfer rate is 400–800 MHz using a 200–400 MHz I/O clock, and DDR's range is 200–400 MHz based on a 100–200 MHz I/O clock.

decide urself, depends onur system support and ofcourse ur buying capacity.

DDR3 is better

Buying RAM


Ok first off, you're right. 4GB at 1200MHz would be ideal, but there's only one problem. Alot of computers don't have a 1.2GHz front side bus.. so even though the ram can run at that speed if you're frontside or backside bus can't keep up it's pointless. Fist figure out how fast your FSB (front side bus) is and buy your ram accordingly. Ideally, 1GB at 1.2GHz will out perform 2GB's of 667MHz. But there are other variables to consider, but i'll spare you the essay.
Also keep in mind, if you're replacing ALL the old ram in your system then you'll see a nice performance gain, but if you're only adding to your existing ram, the new ram stick(s) will only run as fast as your old ram.. so if you have a stick of 1GB at 667MHz, but buy two new 2 GB's at 800MHz, the new sticks will only run at 667MHz, because ALL your ram must run in sync. 
Hope i answered your question!

RAM comparison for asus p5q se/r mobo


Hi,

Appreciate the direct "Ask Me".

Interesting choice which would seem to boil down to quantity over quality. Personally, I would rather go for quality, that is the highest motherboard acceptable/allowable speed of the memory. Even if the memory is only 2Gb and you can run it at max speed (with latency 2) it should dramatically improve performance. Additionally, the 2Gb (low compared to 4) could be compensated with an efficient memory management of the OS (hopefully XP and not Vista). Memory usage/management could be tweaked at the registry, msconfig, Startup and general ways of how the PC is used.

It would be appreciated for a postback/update if and when you have installed your choice of memory and hopefully, I can be of further assistance with a few tips on Memory usage/management; tweaking.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

4gb ram not detected


hey
First of all kindly specify what how many rams slots and how many ram chips are there
like 1 X 4GB or 2 X 2 GB
Generally,
with RAM there can be a few problems
1) the frequency of ram whichmotherboard supports might be less than the freq at which the ramyou are puttin works, hence in this case RAM wont work on this motherboard and ull have to get the RAM replaced
2) some motherboards donot support a 1 x 4 GB RAM where as they might support a 2 X 2 RAM (ifyou do have 2 mem slots for ram)
and then there is the mosttrivial problem of the slot not being clean or arm not being putproperly, i can think of ne other reason for the ram not workingproperly..
For further assistance feel free to mail me at

cheers
