I suppose one could substantiate the 8GB actual usage by doing benchmarks using 4GB and 8GB in a T61 and comparing the results. Has anyone done that?

I don't know where you're going with this. In a 64-bit environment, *61-series (excluding "Z" units) can most certainly use 8GB of RAM. When Intel first announced this chipset, 2GB was the largest single DIMM produced and that's where the 4GB limit cited by both Intel and Lenovo comes from.

It's really *that* simple.

The main reason for recommending/using DDR2-6400 modules is, that they run cooler than DDR2-5300 (and quite often they are also cheaper).

The X61 remains running Windows 7 as Run10 rubs me the wrong way.... don't like Cortana waiting for me to talk to her.

There were days I must have had 1/2 dozen such timeouts... they were very aggravating. The computer would become completely unresponsive. Windows Event Viewer Windows log showed iastor() timeouts with the storage device, obviously the SSD.

It seemed I was the only person on the planet who had to say that moving from a HD to an SSD was a terrible experience, all things considered.

Running Intel SSD Toolbox's Optimizer (weekly, and then daily) seemed to slow down the frequency (I may be mistaken there), but it certainly didn't resolve the problem. I thought the SSD might have been bad, but I was uncertain and I let the 3 year warranty slide by. One person posted that if I tried to RMA the SSD, I'd have a very frustrating experience.

I'm glad the update to Windows 10 solved the problem for you, but just in case anyone else is suffering with this and doesn't want to install Win 10, the problem is caused by Device Initiated Power Management (DIPM), which can be turned off in the Intel SSD Toolbox. The program will complain that it's a recommended feature, but the slight increase in power consumption is more than made up for by not having these periodic freezes.
