Ehr.. aight, we have a paging file because PC's have a limited amount of memory, and lots of harddisk space. The only reason to put something in "virtual memory" is because it is too expensive to put it in real memory (aka, hardware RAM). Putting the page-file on a RAM-disk defeats the purpose of having a page-file. I also have an SSD, and did not believe there should be a page-file with 16Gb worth o' memory. I have had recommendations here to do otherwise and am happy to have followed the advice. Kiran Satish wrote: Any ideas? Having created my own ram-disk[^], I would say that performance is limited in a number of ways. One of those is the limitation of the speed of your memory; virtual memory is slower than blocks of data pinned into physical memory. Did that make my RAM-disk faster? No, it is limited by the driver itself, bottlenecking at 48 Mb/s, which is actually rather impressive. Works nice if the RAM-disk leaves at least 6 Gb of free working memory; it is fast in terms of access, making up for the lack in terms of transfer, and thus doing nice when manipulating lots of small files.

Yeah, that's something you can easily look up though. It's sort of trivial at this point that most CPUs have multiple cores and a shared memory cache.

I guess you are right. A Router must be a Switch with ARP lookup logic to determine which port to switch to.

What? They must be incapable of writing a usable windows driver then and their suggestion is a kludge. I repeat, kernel code is perfectly capable of pulling data off a USB device. It can handle data way way quicker than a USB device can produce it. All they need to do id provide a half decent driver and you wont have to buy extra hardware.

Check. Bluetooth is out for this gig. The reasons you enumerate are exactly what went through my head. Obviously, you're a smart guy. :cool: :laugh:

You will need voltage meter for this.

Run pc in safe mode if working well there then it's driver problem.

Why are you stressing on sim adapter

First of all always look for well known suppliers, that will give you better guarantee. Then look for a true sinusoidal UPS, which means that the output is sinus shaped resembling the line waveform. The cheaper square-wave devices can create problems to switching power supplies of PC and other electronic devices. For more or less the same reason check the minimum allowed load power factor, this parameters directly deals with current phasing of inductive loads, but for electronic devices lower power factors means that the UPS can tolerate higher waveform distortion and the harmonics generated, again, by switching power supplies of electronic devices. If you are looking for medium-high power UPS's looking at characteristics you'll find also an harmonic THD distortion, the lower the best. About surge protection don't worry too much, an UPS device by default give surge protection: A surge is a fast transient overvoltage of power line (up to 200-250% of nominal value), because an UPS output is controlled and regulated you should be theoretically free from them. Another important characteristic is the autonomy: how many minutes of power it can deliver at nominal power. This defines the dimensions of the battery pack. Choose the right time you need, the batteries are very expensive and are also delicate. Remember that batteries have a lifespan (that depends very much on ambient temperature, higher the temperature shorter the life), good quality batteries will guarantee a life of 18-24 months at 25°C +/-2°C.

I've always just used an ink-jet all-in-one and called it good. I used to buy HP, but the materials seem flimsy now, so my current device is from Brother. There are some things that just aren't worth spending a lot of time thinking about. Go to a store that has a bunch on display and choose one.

Go for the two in one option if oyu have a choice. I don't have a choice as my ISP provides me with a fibre router(fibre cable in and one cat5 out) - I run a router/gateway off that. My main computers then run off the gateway via Cat5 and I also have the wireless, on the gateway, switched on so that I can use mobile devices around the flat. “That which can be asserted without evidence, can be dismissed without evidence.” ― Christopher Hitchens
