Some thoughts about overclocking....

My latest experience in overclocking AMD 9850BE inspired me to write some words for those who will go this way. This CPU, as you know, have unlocked multiplier so I start moving it higher - upto x14. Only this particular setting in BIOS - system works fine in Windows XP 32 bit = 2,8 Ghz work stable as with default value, but Vista 64 give BSOD. Playing with different CPU voltage settings I make it work - but feeling of stability gone. I try to find out whats the reason of such different results - working well in XP and crashing in Vista 64. Was found that overclocking in 64 environment- both XP and Vista make system less stable , perhaps of tighter timings. Another part of the problem - chipset - people got better results with 64 bit vista overclocking on AMD chipsets (790fx e.g) rather then on nVidia 780a chipsets. Maybe some BIOS bugs take place, maybe different motherboard have difference in voltage stability - nobody knows it for sure.
So, if you plan to overclock your AMD system and you using 64 bit OS - best choice is DFI motherboards with 790fx chipset.

Intel I218V and Intel I211-AT driver solution for Windows Server 2012 R2

Image
 Its appears to be a common problem with this network adapters and server versions of Windows. This post solves problem with Server 2012R2, but it can be used for other versions of Windows Server i.e 2008, 2008R2, 2012 and 2016. There are now official drivers for Intel I211-AT and Intel I218V. But there are drivers for same adapters with different letter indexes. Idea is simple - Intel separates chips for desktop and server versions, forcing  to setup more expensive versions of this chips for servers. I`m not sure if there any serious difference, but  Asus  use desktop versions for their motherboards since they targets for desktop segment. So its incorrect to blame Asus for not supporting Server versions of Windows on support page. At the same time many users would like to install Windows  server  OS on their Asus motherboards. Funny situation - Gigabyte uses cheap Realtek network adapters on their motherboards and have no problems. But Intel adapters are more powerful.

How to choose printer for everyday use ? Information for customers who going to buy printer but hard to choose the right one.

At first I thought it will be comprehensive guide in buying printer for home users, but soon I found out that it is a very complex article. So I will try to write only summary to  provide you with basic ideas how to select printers so this post will be  universal and easily  understandable.    In this post I am gonna write only about ink jet printers. It is common type of printers people buying for home use because of price , ability to print in color and ability to print photos. If you not going to do color printing I guess you will buy laser jet printer without any doubts.    I got my first ink jet printer in early 90s - it was Soviet black and white printer MC6313 - it has very compact size even by modern standards. Huge difference in quality and noise to matrix printers that was popular at that period of time.    Soon first color ink jet  printer arrives - Epson Stylus Color, then was Color II and after that time - color printing at home goes cheaper and cheaper and becomes m

CoolerMaster Cosmos II and Corsair H115i Pro installation and tips.

Image
Searching for the better way to install this liquid cooling system, Corsair H115i Pro,  in my Cosmos II case, I found the most efficient and quiet way. At first sight, there should be no obstacles with this since this case has an option to install 140 mm fans on top of this.  Since  H115i Pro is closed loop system, so the only way is to install the radiator beneath the top side of the case and put fans outside on top. First of all, I suggest to cut out holes on the top side for better airflow of 140 mm fans, By the way, Cooler Master in their Neptune case they made a grill instead of fan holes - so you can use 140 mm full power! So I cut out to extend the fan holes for larger fans. This makes fans work more efficient and as a result lower fans speed. I kept screw holes for 120 mm fans in case if I someday will change cooling system.    You could not install fans on radiator inside since additional power connectors on most motherboards ( at least on Asus boards)
