Understanding how windows uses RAM - Why you Want Loads of it!

 A history Of Ram Caches, prefetcher and superfetch!

Ever since the dawn of computing random access memory (RAM) has always been a limiting factor, it determines how much information  the cpu can "juggle  in the air" to keep a program open and to display its contents, early on programs were made to fit specific ram requirements (not to mention much earlier you only had around 600kb of base system memory to work with!!) because RAM was never cheap, at around  100$ for 4 megabytes (yes MegaBytes), windows 1.0 came and demanded for more, these where the days where you could only open 2 applications at much, before windows notified you ran out of memory!

 You could only run as many programs that the memory could handle 

these two are too big for the system memory!

16GB of ram and How to Migrate Raid0 from one system to another (different chipsets/controllers)

DISCLAIMER: This guide is specific to newer motherboards that include  raid chipset in some or most of the sata ports, from both brands of AMD and NVIDIA, the success rate depends on many variables mainly the  hard drive interface controller and how well the operating system can deal with the swtich to another one (this resuslts in blue screens of death in few ocations, always have a back up of your data!)

I NEED MORE RAM! (8 is not enough!)
As you may remember on a previous post (double your speed with raid0) i told the tale of how i doubled the speed of my computer by adding together 2 hard drives and form a RAID 0 array, dividing the write times in half and increasing the read performance by two, i slapped 8 gigs of DDR2 ram to that computer and i was gold! resources available at all times... but having many open projects and a game by the side, really slowed down my system!

100+ FOLLOWERS - Thank you
Posting my experiences here on this site,  i never expected to have such response, i have visitors from all over the globe,  people seem to love what i have shared so far,  and  i have been given a little help from my sponsors as well, i realized i should thank you all for your support, something that encourages me so much and makes me smile :D

COMPUHENTO.COM : godaddy.com to the rescue
Well the time has come to roll up my sleeves and   take things a bit more serious.. nothing big of a change here, other than to continue to  give you what i have so far, i decided to change my webpage name to something shorter something unique, COMPUHENTO  a word that joints my rl nickname  and the computer acronim of what i have dedicated my life to.

Nvidia G84/G86 = Dead Laptops ( how to revive dead laptops)

Greetings and welcome back, today we venture into the world of reviving dead laptops due to the failure that was the G84 and G86 Chipset from nvidia, check it out here, you might be surprised on how many models from hp/compaq and many other companies are affected.

HOW WE GOT HERE

To recap a little, we saw last time, how Nvidia ventured forth into an unknown territory by utilizing a new and untested proccesing scheme that involved materials and bindings that technically operated at a given TDP, but ultimately  after the disaster and trough testing was discovered that function with a higher TDP, coupled with the unsufficient cooling solution provided by HP/Compaq and you have the recipe for disaster: A  Chipset/Video part  that heats up beyond its structural treshold and breaks down causing death upon its wake.

Nvidia G84/G86 = Dead Laptops Everywhere! (how to check and save your laptop) Part I

COMPUTERS - Smaller costs more!
Computers, Laptops, netbooks and most portable devices all share the same components but at a smaller scale, with  central proccesing units(CPU), storage solution, graphic proccesing units (GPU), screen for output, keyboard or tactile pad, and many other components that  work together in harmony for you pleasure! o.O

Manufacturing small scale electronics is a expensive business, and thus why laptops and small devices always seem to cost much more than their desktop counterparts, every year companies try to push the envelope and shrink down the manufacturing process, developing smaller and efficient parts that generate less heat and require less energy to function.

CHIPSET - the heart of all

Capacitors! - revive dead Video cards and Motherboards (and other electronics)

Disclaimer: while it is possible to repair power supply unit capacitors, just stay away from them and buy a new one!, they deal with high voltages and amperage, and  should not be tampered with ! this guide deals with low voltage capacitors!


Computers and electronics: We have made our life around them, and sometimes rely heavily on them, everything is fine and well until one day, when  you try to boot your computer, the fan noises are made, the hard drive spins to life, but there is no image on the monitor, this is possibly not a power supply issue, it might be bad ram, but if everything was well and running up to that moment, you might very well be looking into the eyes of death!. A dead Motherboard or Video card!!!  All is lost!abandon ship!

Last Part! - Hard Drives: How to certify a drive for good measure!

DISCLAIMER:
Even if you plow your hard drive trough all of these programs and get the green light on it, there is no stopping fate from making your drive die the next day, so back up often!
( 9000+ Visitors :D! ty)

Welcome back to this humble guide I hope you have enjoyed the insight on the programs that i use to test and certify  hard drives, this time we finally take a look at how to make sure a drive will perform reliably both in data preservation and  performance within windows!
