memory upgrade question

hi all,

i have purchased 2x2gb of ram from crucial.com and as adviced they are compatable with my asus p5n-e sli motherboard
this is the motherboard page:
ASUSTeK Computer Inc. - Motherboards - ASUS P5N-E SLI

and these are the ram chips or whatever they're called that i purchased
4GB kit (2GBx2), Ballistix 240-pin DIMM, DDR2 PC2-8500 upgrades for ASUS P5N-E SLI Motherboard, CT1196814 from Crucial.com

my question is are they going to work with the previous ram chips i had or it would be better if i remove them and just install the new ram chips

these are the details of my old ram chips

2x 1GB 240p PC2-4200 CL4 8c 128x8 DDR2-533 1Rx8 UDIMM, Micron, BMI, MT8HTF12864AY-53EE1

thanks

You do not want to run those together.

Even it does work, your new expensive RAM will operate at the speed of your old RAM.

I agree with DeVandal. The speeds of the old memory is too slow for you new memory and may not even run. The best bet is to just remove the old memory and use the new higher speed memory. Download CPUID - System & hardware benchmark, monitoring, reporting. After you install the new memory check the Memory tab and it will show what options the memory is set to. Then check the SPD tab and it will show the settings the memory can run at. To get full performance you may have to go into the Bios and reset the memory settings. Let us know how it works and if you need any more help with the settings.

You will need a 64-bit version of Windows 7 to use all your 4GB

In the picture that you provide above, you are running your PC-8500 (1066mhz) RAM at 400Mhz...so with it being DDR2...when you double 400 you get 800Mhz. The way to get your memory running faster than 800Mhz...up to it's maximum of 1066mhz...is to start to experiment with overclocking your CPU. Since you have a Packard Bell (in your specs), you might find that you cannot manipulate things like FSB speed though. You will have to look around to be sure. But you could take your RAM up to a FSB speed of 533 (533 x 2 = 1066). Everything will depend upon whether your CPU can handle it and the extra heat.

With a FSB:MEM divider of 2:3...this likely means that your FSB speed on your processor is 266Mhz...and your memory is now running at 400Mhz (3/2 x 266FSB). This would be right with your orignal ram as 266Mhz x 2 (for DDR) is 533Mhz...which is what your original sticks were rated at.

You are running at the highest "standard" setting for your memory. The two listings for EPP are what the memory can handle but is considered over clocking. You will notice the max voltage for those settings is 2.0v and higher voltage may be required for the memory to be stable at those settings. All these settings should be available in the Bios but I don't know where. You may want to post in the Overclocking section of this forum if you want to give it a try. This is where the Memtest comes in handy to see if your memory will be OK at the higher settings.
