Hi everyone!

I have upgraded my old (2009) Toshiba Satellite A665-s6080 laptop from 4GB (2x2) DDR3-1066/PC-3 8500 RAM to 8GB (2x4) DDR3-1333/PC-3 10600 RAM.

After doing so I could not boot computer. BIOS was doing fine, he was recognizing 8GB RAM, however, Windows 7 (x64) Home Premium would not boot.

After many attempts, I put old 4gb (2x2) RAM back and booted laptop. Then, I changed "Max Memory" setting by checking it in "Advanced Boot Options" and setting it to 4gb. It lowered "memory usable" to 2.92gb.

I put new 8gb (2x4) RAM back and it boots! But...then i realized that even though Windows recognizes 8gb the "usable memory" is still 2.92gb. I decided to change "Max Memory" setting. First unchecked it. Windows would not boot. Then repeat the process with putting old ram back to boot it and this time set MAX to 8gb. But again fail. Windows refuses to boot.

Factory reset of Windows and Update and Reset of BIOS, nothing helped.

both BIOS and Windows see and recognize new 8gb RAM. However, I am stuck with 4gb MAX memory and 2.92gb usable only...

Here is my CPU: Intel Core i3-370M @ 2400Mhz.

Here is my Motherboard model and chipset: Toshiba NWQAA, Intel HM55 (IbexPeak-M DH).

I also run both CPU-Z and HWiNFo64. Both of them see and recognize 8gb RAM (2x4).

Windows Memory Diagnostic Tool says "no error detected".
 
Solution
SOLVED !!!

The problem was in density of RAM !!!

If you had originally LOW Density RAM (like the one below) with 16-chips (8 on each side) then buy the same LOW Density !!!

If you had originally HIGH Density RAM (like the one below) with 8-chips (4 on each side) then buy the same HIGH Density !!!

No, old ones are 1066 MHz, but because you cannot really buy them now I bought the lowest available ones which is 1333 MHz. But CPU-Z and HWiNFO do not show any problem, and they show that new RAM is operating actually in the sane frequency now.
Here is screenshots from CPU-Z

And here is from HWiNFO with new 8GB

Okay, Try running the laptop with 1 2 gig stick and 1 4 gig stick. the two gig slower stick being in the first memory slot and the second 4 gig stick being in the second memory slot and see how much of the 6 gigs it says is usable. If this works then that's as good as you'll be able to get with the current ram you have because the computer is going to see the specs of the ram module in the first slot and apply those same specs to the ram module in the second slot, aside the actual size.

Did it, nothing. It boots if I put just 1x2GB stick, but it does not boot if I put 1x4GB stick. Tried combinations 1x2GB+1x4GB and still no booting. There are only differences...

with 1x4GB it just shuts down after BIOS
with 1x2GB+1x4GB it reboots itself after BIOS. BIOS btw sees 6GB of RAM
with 2x4GB (and "Max Memory" unchecked) it stops at "Starting Windows" and does not load it any further. Here also BIOS sees 8GB RAM
with 2x4GB ("Max Memory" checked) it boots, but obviously max memory is limited to 4GB
