I think In my post I said that the spd tabs showed what they could run at. The memory tab shows what they are running at.

You did. You and I were typing at the same time, you just hit enter a minute or 2 before I did. I was intending my comment to seekermeister...not you.

If that is the case, then why doesn't it show options for setting everything at PC-12800 and at 1.7v as the RAM is designed for?

Unsure of that. It definitely seems to be missing. Perhaps it's just something that it's reading from your mobo, CPU, firmware version, etc...and then limiting the choices that it's showing to you.

I don't use Patriot RAM sticks myself, I usually use Corsair and G.Skill. Not saying Patriot is bad, just not experienced with it.

It particularly bothers me that it shows PC-8500 as the MAXIMUM bandwidth, rather than PC12800. If this is due to an issue with one of the components, or some setting, how would I determine which? If I understood that, then I would know what to do, or which manufacturer to seek a solution from.

I have had the same issue before. It is probably showing the speed the dram controller set it at and not the speed it actually is. The more important thing is what it is actually running at.

The SPD tab can be, and often is "incorrect". Here is a thread;
Why is CPU-Z showing different ram bandwidth? - Hardware Canucks

See the #4 response in the above, it backs up what I just said.

Here is another post on another forum with the same type of concern;

And finally, one more;

I think you are chasing a RED HERRING.

Red herring or not, one thing that all of the diagnostic programs that I have tried agreed on, is that the actual RAM frequency is running at 1333, not 1600. I know that it has been mentioned that it would be necessary to "tighten the timings", but what does that mean exactly, since I do have it set at 7-7-7-20 as the RAM is designed for?

THe SPD tells the CPU what RAM is installed and the CPU uses these settings at startup.

also the RAM has to run at the same speeds and the SPD's on that tab read diff. things.

Have you tried using just one stick at a time? I have not seen that in the discussion yet.

Here is info on tightening/loosening timings and pretty much what the timings are
