memory - Is it possible to underclock ram

There is an application called granola for windows that can be used to underclock the cpu to consume less power. Is there also an application that can be used to underclock the ram to consume less power when you are just using the computer to download?

Answer

If you have an OEM motherboard, you can underclock RAM by putting slower RAM in, in place of your standard RAM. Your motherboard will read the SPD and use the timings there.

If you have an aftermarket motherboard (such as Asus or Gigabyte), it may come with an overclocker's utility (Windows application) that allows you to change settings such as the FSB multiplier (or HT or QPI). This would allow you to run the RAM slower. There will be a small but measurable performance hit. Usually these utilities overvolt automatically for overclocking, I don't think they undervolt automatically though.

For true flexibility in undervolting/underclocking, any motherboard oriented towards overclockers should give you the functionality you need to do what you want, but you will probably find it in the BIOS setup, not in an application.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y

networking - Windows 10, can ping other PC but cannot access shared folders! What gives?

I have a computer running Windows 7 that shares a Git repo on drive D. Let's call this PC " win7 ". This repo is the origin of a project that we push to and pull from. The network is a wireless network. One PC on this network is running on Windows 10. Let's call this PC " win10 ". Win10 can ping every other PC on the network including win7 . Win7 can ping win10 . Win7 can access all shared files on win10 . Neither of the PCs have passwords. Problem : Win10 cannot access any shared files on win7 , not from Explorer, nor from Git Bash or any other Git management system (E-Git on Eclipse or Visual Studio). So, win10 cannot pull/push. Every other PC on the network can access win7 shared files and push/pull to/from the shared Git origin. What's wrong with Windows 10? I have tried these: Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings\ File sharing is on, Discovery is on, Password protected sharing is off Adapte
