Hey ben, 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.

Re: RAM comparison for asus p5q se/r mobo
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.

Max speed supported for your mobo is: DDR2-533 You will have to buy (4) 1gb sticks (2gb sticks not supported) To use all four gigs of ram you need a 64 bit os.32 bit only supports 3gb of ram. Hope this helps! Here is the specs :
ASUS A8M2N-LA (NODUS-GL8E) (DDR2-533MHz) Memory
4 (4 banks of 1)
non-removable base memory
Machine name: ASUS A8M2N-LA (Nodus-GL8E) Motherboard
CPU options: Supports AMD Athlon 64, Athlon 64 X2 and Sempron processors.
Chipset: Nvidia GeForce 6150 LE Chipset
Front Side Bus options:
Memory Speed options: PC2-4200 DDR2-533 240pin SDRAM DIMM
- Motherboard manufacturer's name: ASUS A8M2N-LA
- HP/Compaq name: Nodus-GL8E
*Actual available memory may be less w/o 64 bit os
Well...i never heared of a 16gbram mobo and also no OS is able to support it propery and also u don't need so much memory but whatever.You could use smaller modules like 1gb or 2gb but you must know wht type of memory it uses and also what's the minimum amount of ram that can be used.
Sorry to disagree with you Electech1, but you don't quite understand how memory works. Let me explain:
The memory transfer speed is determined by the memory bus speed. This is determined by the motherboard in question. The specs for this should be listed with the motherboard specs. Installing memory sticks that are capable of a higher speed WILL NOT make the memory access faster. As an example, the old PC100 and PC133 memory sticks worked with 100 and 133MHZ bus speeds respectively. Installing PC133 sticks into a machine designed for PC100 would work fine, but at teh same speed as PC100. Installing PC100 memory sticks into a bus designed for PC133 could work but would not be guaranteed and could fail in odd ways. This was because the PC100 memory was not tested to work at the higher bus speed. The bottom line is that the memory installed MUST be matched to the bus speed.
Depending upon the design of the process and memory system, it is possible to have parallel memory accesses. The physical number of memory sticks will not have any significant impact on this.
In terms of the processors:
Dual core means that both processors can be active performing a single program in parallel. This means that a process that requires 100 cycles of processor time can be completed in less than 100 cycles of true time because of parallelism. This happens at the instruction level and is handled by software language compilers that generate the end instruction stream in such a fashion as to provide parallel operations. I could go on for days on how this works, but realize that in effect this type of design allows for parallel operations which will cut down the actual time required to complete functions.
The amount of parallel operation will depend upon the type of program being run. The more calculation intensive the application, the more likely benefit of parallel operations.
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.
I had the same problem and ASUS tech support was of no help. I did however find the culpret in the BIOS setup. Go to Advanced, Chipset, NorthBridge Chipset, and Memory Configuration. Set the Bank Interleaving to Disabled and save the settings. Check these settings also while you are there:
Channel Interleaving = Auto
Enable clock to all DIMMS = Disabled
Memory Tristate = Disabled
Memory Hole = Enabled
Unganged Mode = Enabled
Power Down Enable = Enabled
Power Down Mode = Channel
