Ddr2 1066 4gb? ddr2 800 8gb? ddr2 1066 4gb+ddr2 800 4gb?

Specs: Windows 10, 8GB
Windows 10 64bit
ASUS M3A78-CM
AMD Phenom II X4 940 BE

This PC has DDR2 1066 4GB (2GBx2). I have DDR2 800 8GB (2GBx4). Should I use all DDR2 800? The x2 DDR2 1066 + x2 DDR2 800? Or spend $18 to get x2 more 1066?

I may do a soft OC but the PC is mainly for light gaming and mostly Media use.

Crucial.com

Download/run their free (very safe to run) scanner utility. It will show what”s best for the system.

Their prices are reasonable and the chips they recommend safe, sound, reliable. And their support excellent.

They’re my first port of call for RAM info. and SSD too.

The memory controller in your Phenom officially supports up to DDR2-1066 so technically, that would be the best choice. If you mix the 1066 + 800, it will all run as 800 but you will have 12GB. If you already have it, just install it & try it. It should perform much better with 12GB @ 800 than with 4GB @1066.

You mentioned a "soft overclock", what do you mean by that? Since you have a Black Edition Phenom, all you really need to do is increase the CPU multiplier & not touch any of the other settings, but be aware that changing the multiplier can also change the memory speed. Use CPUZ verify the settings & to check memory speed.

Yes, this is what I mean by Soft OC vs OC'ing to the point you have to start replacing/adding hardware.

I assume 'soft overclock' is the same as 'Mild Overclock' for the more timid user. Certainly safe for everyday use. Certainly not very fast but easier than checking all settings, temp, stability, etc. OK for some, I guess.

Ok so, I think you miss read/understood because I can't reach 12GB 800 with only x4 DRAM slots.

In addition, I found x2 1GB 1066 laying around so my max options are 6GB 1066 or 8GB 800. Which would be best?

Right now with the 6GB 1066 and no OC I am at a 3:5 ratio. I read just as much ratio doesn't matter anymore as much as it does. I know in higher end DDR3 and DDR4 it really does not but should I try for 1:1 if I use the 1066? Or, if you think 8GB 800 (2GB more DRAM) would be the better, I should be at 1:1 off the bat right? and as long as I just use the Multiplier to Mild OC that shouldn't change?

riider can give you recommended OC settings to achieve results and get you to the right ratio.
I do not get involved with AMD so I cannot answer as specific on them. Generally with the older generation CPU's getting the 1:1 ratio and optimum FSB was the most important and the starting point. Once you get those right you can raise the multiplier, Occasionally to get the right starting point, especially with faster memory, you need to raise the frequency and lower the multiplier to start with, then raising the multiplier slowly, testing for stability. Even if you only get the optimal ratio and frequency, you are ahead, even with the same end 'speed' you are ahead in total system performance. Then you can clock up as your preferences go and the system is stable.
