Question 1

I want to replace existing memory with this 4gb (2GB X2)
My System: ASUS M2N-MX SE Plus Motherboard
Operating System: Currently running Windows XP Professional (5.1, Build 2600) Service Pack 3 Moving to Ubuntu ver. 12 soon!!!
Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 4400+, MMX, 3DNow (2 CPUs),~2.3GHz

Will this be compatible?

Accepted Answer

Absolutely. Your motherboard has native 1066 speed support and your CPU will utilize it, so it will not only be compatible but your system can make use of it.  When you move to Ubuntu, all 4 GB will read instead of the 3.45 you will see in Windows XP. That is simply the maximum that a 32-bit OS will accept, and doesn't indicate a problem at all.

Question 2

Will these memory sticks work on a six year old ASUS P5B motherboard?

Accepted Answer

G.Skill:
DIMM 4GB (2GBx2) 	
DDR2 1066
non-ECC, un-buffered, dual channel

Asus P5B motherboard
4x DIMM, max. 8GB
DDR2 800 / 667 / 533 MHz
non-ECC, un-buffered memory, dual channel
*** Memory tuning from 400MHz up to 1066MHz ***

This memory is faster than your mobo requires. It should work fine at the lower mobo speed. However, because you can overclock your mobo, you might be able to get them up to 1066. Set your BIOS at 800 to start and experiment from there.
Don't wait too long to buy new DDR2 memory. It's getting harder to find and more expensive when you do find it.

Question 3

i have dell optiplex 745 .... can i use it?

Accepted Answer

I'm not familiar with the Dell Optiplex 745.  I purchased this memory for my custom built PC. I can report that the  memory seems stable and performs very well.

Question 4

can I mix and match this memory with khx8500d2k2/2g?

Accepted Answer

The timing is the same but voltage requirement is different. This is a risk.

Question 5

I already have these in my desktop computer, was looking to expand the memory.  Can I just buy another pair and have 4 of these? (4-2 gig memory for a total of 8 gig memory?)

Accepted Answer

This will depend on your motherboard. Find it's model on the PCB, and look it up on the Web. The manual should state the possible memory configs for it

Question 6

I have a 5 year old Gateway with 3gb of ram.  It supports up to 8gb.  It says it supports speeds: 800, 667 MHz.  Will this ram work on my machine?

Accepted Answer

Typically, if the memory speeds supported are 800MHz and 667MHz that means you need DDR-2 memory, not DDR-3. You should double-check this at the Gateway website before buying new memory. You also mentioned that your computer has 3GB of RAM. This usually (but not always) means you are running the 32-bit version of Windows (as opposed to 64-bit Windows). Again, you should double-check this before buying anything. If you have 64-bit Windows then go ahead and add more memory. But, if it's 32-bit Windows then the system won't recognize anything over 4GB total memory. A different option to really speed up the performance of your computer is to install a Solid State Drive (called SSD). This will make your computer boot up and open programs MUCH faster than your regular hard drive. It really makes your old computer feel like new - or even faster than new! SSDs have recently become more affordable so give this option serious consideration. Good luck!

Question 7

Does this come in 4gb modules instead of the 2gb?

Accepted Answer

In the Performance series, I believe the only 4GB module is F2-6400: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=F2-6400CL5S-4GBPQ&N=-1&isNodeId=1

Question 8

I have  an Asus P5Q pro Mobo, Am upgrading to intel core 2 quad, Q6600, 1066 FSB. Will this memory work?

Accepted Answer

Yes it will work, make sure you have a 64 bit OS to address all 4 GB of memory.

Question 9

I have a EVGA LGA 775 FTW mobo and CORSAIR DOMINATOR 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066

The memory requires 2.1v CAS 5 and 5-5-5-15.

Would this work for the mobo and with the existing memory? Yes, I have 2 available slots.

Accepted Answer

yes, it should, but you will not get the maximum speed possible unless you match the same memory in all the slots.

Question 10

I have an ASUS M2N68-VM AM2+/AM2.  It can take a maximum of 8GB memory (4 X 2GB sticks).  I'm currently running 4GB (2 sticks), G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 1066 (PC2 8500) with timing 6-6-6-18 and cas latency 6, Voltage 2.0V.  I need an additional 4GB, and I'm thinking of adding these to my existing installation.  Will they work together?
