DRAM has to be the worst memory ever created. Seeing the variation that people see here tends to illustrate that. As the lithogrophy shrinks with DRAM, the possiblity of variation increases as there is less margin for error. The difference between high speed memory and mediocre speed is simply binning: IE it is all the same die, but they are testing at different speeds: IE you run a test at 2133MHz if it passes you test at 2400Mhz, if it fails it gets labeled as 2133 since that is the last test that passed. This is the same way they they do CPU clock frequency, hence the reason some lots overclock better than others. The joy of shrinking lithography...I guess DRAM is not terrible, still better than NAND Flash design.

This whole Whitelist bothers me, what bothers me even more is it is not a white list, it is a special version of the card. I bought a new 2230 card because mine died (did not even show in Dev Manager on Linux or Windows, I dual boot). Told me unauthorized card, despite the same model number. I then noticed that the card has a special ID, my guess is specific to Lenovo. Having worked to certify wireless products, I know what a pain it is. However, that is not the reason for this restriction. The Intel 2230 is modular certified, what that means is that if you use the antenna that it was certified with (which almost all laptops use), you do not need to certify again, simply show the FCC ID of the module on the system (IE the laptop) and send your $$ to the FCC then you are good. No testing, nothing, at least for US and CAN (Canada mirrors the FCC rules, just send them a check and you are good to go. So the only reason to make this restriction is to sell their version of the 2230. That sucks, and I have a disabled laptop because of it.

It could be a driver or the card. Mine turned out to be the card, which failed hard shortly after the connection issues, however a new drive as suggested would be the first thing to try. You can also try booting a line Linux CD and see if running in Linux for a while is any better, if it is, would lean toward the driver as the problem, if it has the same problems, you may need a new card.

I believe it defaults to the HD Graphics, then once in Windows it will automatically switch to what you need. The SLI should not kick in until the integrated NVidia is running. On Linux it depends on the driver, I know I have issues with battery drain because the linux driver does not support the autoswitching, I am thinking I may disable the driver and see if that solves the issue. What is driving the need to boot with HD graphics only?

For a CPU temp that is pretty good, It would be hard to reduce the temp much more without significant modifications (basically you would need to move beyond liquid cooling and start creating an air conditioner. Any reason for trying to get it colder or you going for as cold as possible (which is a good enough reason in my book)?

10-4TB Seagate Drives in RAID Z2 for my home media server running Ubuntu 14.04. I don't have anything working but it is nice to have 28TB of hard drive space at my disposal that is fault tollerent to N+2. Which is good since I have had a fire in there twice (Word to the wise, don't use cheap SATA power spliters, they have a bad tendency to short and start on fire).
