Discuss Older table guild for new it technitions
Posted by: XT
Hello, This guild is simply just some realtive facts to older computers any new it technition should study. The average of clock speed of a cpu with in a house is 500mhz-1.5ghz so this really still can come into use. Some like the floppy table is out dated but is surely helpful when a costumer comes and asks what type of floppy drive would be best for new build. I also have some references for any new it technition whitch will help him/her a great deal. Gievn these tables are of the top of my head may not be 100% accurite so please bare with me. Some people may say you dont need to know this kind of stuff but infact you do and you should memorize it.(simple way to study it is to keep writeing it down until you get it in order(the table) then mix it up and see if you can do it without memorizing the order but the thing its self
And if anyone has used other tables to help them with costumers please add to this list
Now lets start with that floppy table

Well that ends table references i could make a table with 8088 procesor up to pentium pro but they are rairly in use today so i wont but if anyone wants me to. Upon request i will make one.
Now heres good references

and cnat forget quick silvers guild [url]http://forum.pcmech.com/showthread.php?threadid=85589[/url] happy back to work seaon guys

to me none of this info seems useful, is it really necessary to know this in real life for purpose other than taking the A+ certification exam?
Posted by: XT
well when on the job every technition should have a solid foundation of configuarting trouble shooting resources such as irq adresses. and for a tech who upgrades a costumers computer say with a modem or adapter with an already working machine they must know what to set the irq and i/o adresses to. so not to conflict with other components in a pc. And if you go in and dont know your irq tables you will mess something up and spend more time fixing it than the actually computer. As for ram thats general knowlage and for people who take an interest those links are very useful. Floppy drives are getting out dated and not much use to one. But its always good to know it so you can provide a costumer with solutions to an older type of drive such as the 5-1/4 Dsdd and reffer him to the new 3-1/2 drives. I have used floppy/irq/i-o tables many times but the ram table is just really general knowlage. and the more you sit down with a costumer and talk about differences in devices the more they'll come back and reccomend you whitch is a bonus in my eyes. I thought this info was very useful maybe not to others but just put it out there
Posted by: XT
it probably seems not useful to you because your a senior techy. And probably know this already without thinking of it your instinct on the job directs you to do something. Its just a reference guild for junior it techy's who need to replace a floppy drive or a modem.

I am now deeming this a thread to help people in there hardware needs. be it tables to guilds post them here. So we cant forget es/ksine and his guild [url]http://www.freewebs.com/computer-guides/[/url]
Please post info to help new it technitions as i will keep on posting when i find sooming i think is useful.
So if a mod could change my title to. Hardware resource thread. That would be perfect thanks

i will do it but topic moved to tips and tricks
Posted by: nomad
scrap that thought tips and tricks forum was in here(stupid me) it might be a good idea to add one though

How does over clocking work?very brief
Its basically the realasionship between the multiplier and the fsb(front side bus) whitch determins how fast any given cpu/processor should work.
whitch is multiplier x fsb= clock speed. However, today most multipliers are locked so overclocking is mainly done by upping the fsb and v core to make sure its stable.
In the bios or jumpers on the motherboard are where you will be able to up the fsb or multiplier. you only need the option to change one to o/c.
if your bios is not o/c friendly you might be able to find a flash for it that will enable you to.
1-gradually up the fsb. Eg- you have fsb of 100 quad pumped raise it to 103. then test out your systme by running games and normal work applications.
Then check if the h/s and cpu are hot. You can check readings in bios as well.
2-If your system is stable, continue to increase the FSB speed until your system becomes unstable. When you find an unstable FSB bus speed on your system, just back down a notch on the speed and this is most likely your maximum overclocking speed.
Make sure to move in the smallest increments possible and give the CPU ample time to reflect it’s workload by checking the temperature. Simply use common sense in that if you burn yourself when you touch the CPU after it has been powered for over one hour then you need to reduce the FSB speed and purchase an industrial cooler unit.
3-After your system begins to become unstable you can increase the voltage (very slowly) and you may find that your system can become stable.
Increasing the voltage is risky since this could potentially damage your CPU by either sending too much power or the CPU simply overheats due to the increased voltage.
If you are going to increase the voltage stick to the rule of thumb by not exceeding 1 volt. For example if you have a 2volt chip, do not exceed 3volt. Use the voltage increment as a last resort.
