Hello
I've purchased two 2gb ddr2 corsair pc2-6800 for my old asus P5WD2 mob. card, but at boot, it displays memory as "pc2-5300" interleaved.

do i need to make some tweaks to get the best of my two 2gb ddr2 ram ?
a bios upgrade ? may be


thanks for replying

thanks :)
I've looked at bios, ad I found nowhere where to set the timings and speeds manually, do I need to enable settings somewhere ?

besides, I'm still hesitatin to flash the bios to the latest bios , that is still in beta version since 2006 !!

regards

You will have to enable the manual RAM settings most likely. If you can find where in the BIOS is tells you what your RAM speed is, there should be a selection near it that is set to Auto that is something about your RAM multiplier or something like that. Set it to manual and it will unlock options, or it will just go from auto to an actual multiplier.

Thanks :)
looked at the manual which I haven't done since I don't know ... shame on me :)

Mob. card : Asus P5WD2 + intel CPU P4 630 3 ghz + 2 * 2 gb corsair ddr2 pc2-6800

updated the bios using the EZ flash bios utility ( I was struggling first tryin to boot a boot floppy disk :( )

on the bios, I set the AI overclocking to manual ,
cpu external frequency to 200 Mhz
DRAM frequency to DDR2-800 Mhz

I'm interested on the AI NOS settings ... to be continued


Thanks again :bounce:

Its always better to ask than to not know. Theres no stupid questions, and nothing to be ashamed of. Most of us didn't know this and had to either ask or figure it out at some point or another:)

Hello again,
the reason behind this thread is to make sure that the two Corsair 2gb DDR2 pc2-6800 are what they pretend to be,
after tuning the bios ( see ealier thread) the bios displays them as pc2-6400, on windows xp , CPU-Z shows them running at 400 MHz
HomeEverest tools shows them as 2gb DDR2 pc2-6800 running at 400mhz.

Have I been fooled when purchasing those memories ?

thanks

PC2-8500 is DDR2-1066. I know I've seen DDR2-1000 and possibly DDR2-900 maybe? Whatever the case, it will probably show as DDR2-800 (PC2-6400), but is specced to reach whatever the 6800 speed is, but only overclocked. Even DDR2-1066 generally will come up as 6400 and must be overclocked to reach the full 1066 speed. I'm sure if you OC you will be able to reach 850 or 900 or whatever the PC2 6800 is actually supposed to be.
