hi im a bit new to forums ...

iv taken a screen shot but not sure how to insert it ??
it shows cpuz info also cpuid monitor

dusty1976 · 23 Dec 2011 at 17:46

i dont know how to adjust the settings in the bios

Hi and welcome to the forum.

Your post is a little confusing.

Corsair Twin2x4096-6400c5c 4gb Pc6400 Ddr2 Memory = 800MHz

Corsair TWIN2X2048-8500C5C 4GB 1066MHz C5 DDR2 Memory = 1066MHz

Which do you have?

If you want us too see your images then upload them to ImageShack, or similar, and embed the image link in your post.

FYI you have to double whatever speed CPU-Z shows you as it's Double Data Rate RAM.

hi here is a screen shot i have both ...and im not sure if its running the best it can..

i have both ,this is my point i want them all to run at 1066MHz, but it seems from these reading that they not

Orcvader · 23 Dec 2011 at 23:36

Erm, that pic is a bit too small for us to see CPU-Z readings? And are you even sure the 800mhz kit can run at 1066mhz?

Harpss1ngh · 23 Dec 2011 at 23:52

There is no way you're going to get that 800mhz kit to run at 1066. You'll either have to run the lot at 800mhz or buy a new set of 1066mhz memory.

It's recommended to use identical memory for compatibility

HangTime · 24 Dec 2011 at 01:18

My recommendation would be to aim for somewhere between 800mhz and 1066mhz, you may need to tweak the timings for this. Getting a CAS5 PC6400 kit to 1066 is pretty unlikely so you will likely have to settle for say 900mhz. Increasing the voltage would be a good place to start, although do some research into safe limits first.

Also some DDR2 mobos don't overclock as well with 4 slots filled so bear that in mind as well.

Justintime · 24 Dec 2011 at 01:50

As above, even bonafide PC8500 kits don't sometimes make it to 1066 with all slots occupied. If you're just looking for a stable hasslefree rig, i'd settle for PC6400 speeds, maybe with a little extra voltage to try for CAS 4.

dusty1976 · 25 Dec 2011 at 02:19

Thanks all for you input , it would seem the 2 4gb kits i got are not compatable with each other thus preventing me to reach the 1066mhz.

Justintime · 25 Dec 2011 at 02:24

Yes, because one kit is not a 1066MHz kit.

dusty1976 · 26 Dec 2011 at 12:11

ok iv taken out the 800MHZ kit and left the 8500C5C 4GB 1066MHz in but it still not running at 1066?? any ideas ?

Orcvader · 26 Dec 2011 at 12:51

Clock it back up in the BIOS?

dusty1976 · 26 Dec 2011 at 12:59

iv never touched any settings in the bios im not really familar with it tbh

Surveyor · 26 Dec 2011 at 16:03

You'd probably better off with 8GB @ 800MHz than 4GB @ 1066MHz.

dusty1976 · 26 Dec 2011 at 16:04

im gonna replace the lot i think then it will be right

dusty1976 · 26 Dec 2011 at 16:08

Any suggestions on some good DDR2 1066MHZ 8GB if pos would be greatful
here are the specs of my mobo http://www.asus.com/Motherboards/AMD_AM2Plus/M3A32MVP_DeluxeWiFiAP/

Surveyor · 26 Dec 2011 at 16:34

Just run 8GB @800MHz.

The price of new DDR2 RAM is high and I can't see the point for what difference it will make.

dusty1976 · 26 Dec 2011 at 16:42

ill try again with the screen shot this time with imageshack here is the link

Orcvader · 26 Dec 2011 at 17:10

I would leave it as that. You won't notice any difference between 800mz and 1066mhz anyway.
