The desktop wallpaper will go blank, the clock will freeze, and if I try opening something that isn't already open it usually won't work. Anything that's already up works just fine. Restarting the computer always fixes it, but I'd like to know what's going on rather than just ignore it and restart each time. It's done this probably 5-6 times in the last 4 months. Anyone else have experience with this? I have windows 8.1 or whatever the latest version is, by the way. This is usually fixed by terminating dwm.exe and/or explorer.exe (so that they restart), or logging on/off. One of many common problems with Windows, your best option of finding the root cause is to do a clean boot / fresh installation of Windows and slowly figure out what driver or software is causing it. | ||

and this guy talk about Haswell but dont have any sense talk about intel tenchnology ivy brige-e is much better in many ways. Does IB-E actually have any advantages over Haswell? How have I never heard of this? I would never recommend someone to get an i5 on IB-E over an i5 on Haswell, I've never SEEN someone recommend IB-E over Haswell. So.. ? | ||

There aren't anything but Core i7s on SB-E and IB-E. Minimum you get is four cores with hyperthreading. Advantages over Haswell include CPU models with six cores as opposed to topping out at quad cores, 40 rather than 16 PCIe lanes, and quad-channel rather than dual-channel memory. However, you're stuck on an older CPU architecture, and the chipset is kinda dated at this time so no native USB3, limited native SATA3, etc. | ||

Yes so it's stupid to bring up IB-E when we're discussing processors of the i3/i5 price range. Also, Haswell-E says they're going to do 8 cores, apparently it's very new (I just googled this lawl): http://www.anandtech.com/show/7874/haswelle-8-cores-x99-ddr4 | ||

On a mobo with: PCI Express 3.0 x16 2 (x16/x8 or x8/x8) PCI Express 2.0 x16 1 (x4) Would you expect a third card (highend) on this system to have any positive effect (could you even do triple card with this)? | ||

So if you have more stuff that needs to talk to the CPU at a really fast rate, you want more PCIe lanes available to the system. Even though a graphics card has sixteen lanes wired up, you might not be able to allocate sixteen lanes from the CPU to go interface with it. Hence cards can be run at x8 or x4 or other configurations, which means lower transfer rates of data between the two. This can have some impact on performance, but it really depends on the kind of operations that are taking place. For games, having the faster CPU might be more important than having more PCIe lanes beyond a certain point, even for 3x GPU setups. (there are some details skipped above about PCIe lanes from the PCH and potential PCIe bridge chips and so on. also, there is a distinction between the physical slot and the number of "electrical" lanes supported, which just means how many lanes can actually be used for communications) | ||

Some of these kinds of splits are being used to supply lanes for the new storage interfaces on Z97. Often 4 lanes of 2.0 from the PCH (southbridge, the Z87 chipset itself) are used for a slot. Midrange boards tend to have x8/x8 and then x4 from the PCH for the last fullsize (x16 physical) PCIe slot. Note that x4 usage from the PCH could be pulling away lanes from other slots like the x1 slots.

For A->B communications (or vice versa) where you're sticking an extender C in the middle, A->C and C->B links both should be over twice as fast and reliable as A->B directly or it's just going to be worse. Changing positioning and/or antennas is usually better. What's the setup even look like? What's the device you're trying to reach? But yeah, grabbing an old router for this duty is often what you want. All home networking gear kind of blows though, so good luck finding something reliable. | ||

I need to buy a laptop computer for school. I have $1500 to spend (it's a scholarship from the school so there's no point in spending less), the only condition is that the machine needs to be able to run windows. I don't plan on doing anything like overclocking or running graphically intense games. I just need the computer to last four years and be reliable. Of course, I'd like an SSD if at all possible. I'm studying Math and CS so a strong CPU may come in handy. Any recommendations? Sorry if there's a thread on this that I missed. If one exists, please direct me to it. | ||

As for a laptop for $1500, I don't know about high-DPI laptops like MBP Retina. I mean, if you're using Windows, the display scaling is better these days but still sucks. The thinner, newer Thinkpads aren't really like the old ones, but I'd also check out the T440s and maybe T540p (which come in many configuration options). Actually, what's the usage model going to be like? How much do weight, battery life, keyboard/trackpad quality, and so on matter? I'm assuming build quality is most important. What size are you looking for? | ||
