My mother board will also, not support more than four side total. Mean that If i put 1 double sided stick and 2 single sided sticks (Makes for sided total) I am left with a slot available that a I cannot use.
Here is the "Official"quote from the manual.
**Due to chipset limitation, this motherboard only supports up to the total of 4 ranks (4 sides in total) of RAM at max.
*Supports 2 DIMM modules only for yellow DIMMs when over-clock to DDR2-1066
So logically if I want 8gigs of ram in this PC. I'd have to get 4 sticks of 2G single sided.
No we get what you're saying, we've just been trying to tell you that your interpretation isn't correct, though I completely understand your confusion as the wording is very confusing. It's actually a bit complicated, comes down to semantics, I'll do my best to clarify:
The problem is the phrase "double-sided". There is a technical definition and a street definition. Technically, double-sided refers to RAM that is electrically
double-sided. The memory has two SIMMs attached to the same PCB that are in parallel, and the computer can only access one at a time. This is what your manual means when it says "ranks". Electrically double-sided RAM contains two ranks. As far as I know, this is not something that is done in any mainstream RAM these days.
The street definition of "double-sided" is a stick of RAM that is physically
double-sided. But RAM that is physically double-sided is not necessarily electrically double sided, and 99% of the time it is actually electrically single-sided. Your physically double-sided RAM is almost certainly single-sided electrically, meaning it only has one rank and the entire stick can be addressed by the computer at the same time.
In summary, all of your memory sticks are almost certainly electrically single-sided, and therefore by installing all 4 you're not violating the motherboard limitation of only supporting 4 ranks. Any issues you're having are almost certainly due to incompatibility between the different modules. I can tell you right now running DDR2 533 with DDR2 800 is a terrible idea. You'll have to run all your memory at DDR2 533 speeds and loose timings. And the different modules might all want different voltages, which is not possible. You have to feed all your modules the same voltage and run them at the same speed and timings, meaning you're limited by the weakest link.
Even if they were all rated for the same speed, timings, and voltage, they might still be incompatible. This is why dual-channel memory is sold in pairs, they're confirmed to be able to work together. Some memory sticks just don't work well with others.
