Hello, I have an old Dell E6440 which does not turn on from one day to the next. I checked the battery in another E6440 and it is OK. When I put the power supply cable into the jack, the blue LED immediately turns off, so there might be a short circuit somewhere. Then i removed the hard disk...

Maybe a DIY router with an external switch is generally a better choice for tech-savvy users, because you can customise the system according to your own requirements. Many small PCs have several USB ports, but only one Ethernet port. You could use an Ethernet-USB adapter to convert an USB port...

Thanks. In other words: I wanted know if there is a real necessity (for home use) to have multiple Ethernet NICs on a router, because most routers have at least four Ethernet NICs: One connects to the ISP and the others connect to the client PCs. Given that you don't have much traffic within...

Hello, in which cases does it matter if you have multiple physical Ethernet interfaces on your mainboard or only one Ethernet NIC that is connected to an Ethernet switch? The only reason that comes to my mind is that multiple 1 Gigabit Ethernet NICs are a compromise between a single 1 Gigabit...

Hello, when I plug the power cable into the input jack of my DELL E6440 the battery status light turns on for about 2 seconds and immediately goes out afterwards. How can I find the defect?

Thanks. I want to upgrade the CPU because the latest Mac OS version (Sierra (10.12)) isn't compatible with Merom-based CPUs, so I need a Penryn-based CPU like the P8400. When the CPU has a higher FSB frequency it just means that some cycles are wasted, but it should be compatible with the iMac's...

Hello, I have an old iMac 20'' 7,1 from 2007 with an Intel Core 2 Duo T7300 2.0GHz CPU (Socket PBGA479 or PPGA478, 800 MHz FSB). Is it possible to upgrade it to an CPU with higher FSB speed like the Intel Core 2 Duo P8400 with 1066 MHz FSB?

I added some voltage to DRAM voltage and NB voltage, but the system is still instable. It runs for a while and then crahes with a bluescreen. Does it make a big difference if the RAM runs as DDR2-800 or DDR2-1066? My CPU is an Intel Q6600.

That's not the problem, but what I don't understand is that SPD -> Max. Bandwidth says PC2-6400 (400 MHz), which is not correct if the RAM is sold as DDR2-1066 or PC2-8500.

I'm confused, because according to CPU-Z it's DDR2-800 and not DDR2-1066, because DDR2-1066 has a bandwidth of 8,533 MB/s and called PC2-8500. However, the label says it's 1066: RAM module: SPD: Memory running in... ...DDR2-1066 mode: ...DDR2-800 mode:

Thanks. Could adding voltage harm the hardware? What does NB mean?

Thanks. I updated the BIOS, but that didn't solve the problem. The OS starts, but after a while I get a bluescreen with this message: " A clock interrupt was not received on a secondary processor". "Adding a little voltage"? How does this work in practice?

Hello people, I have installed Corsair CM2X2048-8500C7 (2048 MB, 1066 MHz, 7-7-7-20) into my Asus P5Q mainboard. The memory runs stable at a frequency of 800 MHz, but at 1066 it causes the system to crash. My BIOS settings: FSB frequency: 266 FSB Strap to North Bridge: Auto DRAM frequency...

Thanks for your answers. The installed memory is OCZ DDR2 PC2-9200 Reaper HPC Edition 2x1GB, 1150 MHz. I don't understand why the memory is running too slow at 670 MHz and not at 1066 MHz. How can I fix that?

Hello people, I have an Asus P5Q that allows different front side bus speeds: 1600 / 1333 / 1066 / 800 MHz.(http://www.asus.com/Motherboards/P5Q/#specifications). My CPU is an Intel Core 2 Quad Q6600 2.4GHz. However, I don't understand the following values that CPU-Z displays: Memory tab: DRAM...
