If you have a 1600+, i believe that it is a palamino core. They do not overclock to well.
not necessarily true. my 1600+ hits 2000+ speeds. that might not be as great as a new barton 2500+, but it's not too shabby either.
now, Shotalxxx, about overclocking... you will have to open your case. you just will. trust me, it's not that scary. if i had never opened my case i wouldn't know any of the stuff i know now. in fact, the original reason i opened my first computer was to overclock it. just opo your case open to see what everything looks like and see where everything goes. it's informative.
now, about that article. it was written two years ago and msi i'm sure has addressed many problems the original board or bios may have had. is your computer new to you or have you had it for a while? if you've had it for a while i'm sure you would have run into some problems by now if they were to happen at all.
according to the manual, you should have a program called fuzzy logic on the cd that came with your motherboard. this program allows you to overclock your *system while in windows. i've never used this program, but use it in good faith i suppose. apparently you may suggest a fsb speed to the program and upon reboot the computer will set itself to that speed. this method would allow you to overclock the system without messing with the bios or opening your system.
the tried and true method is through the bios. access the bios by hitting the [delete] key when the post screen instructs you to.
*select Hardware Monitor Setup. cpu fsb clock should be 133 already as you have a 1600+ cpu.
*in the field for cpu fsb/pci overclocking, you should be able to select or enter a number up to 164. of course this can all be found on page 26 of the third .pdf
document that you downloaded and read.
*keep the cpu ratio on auto. if you're unable to overclock very high, you might add a little juice by selecting a higher vcore level in the next field down. the defauilt for the 1600+ palomino is 1.75v, but be careful - adding more electricity adds to the heat. you should keep an eye on how hot the chip is getting. this can be done by booting into windows and doing you normal surfing, gaming etc for ten minutes or so and then rebooting and entering the bios again, selecting Hardware Monitor Setup and check the temperature. if your cpu is 50 degrees celsius or less than it's ok. that fuzzy logic program should also have a temperature reading.
*as you increase fsb, the speed of your ram increases as well. it may need a little more juice to add to the stability of your system and that can be done in the ddr voltage field. again - electricity adds heat so be careful.
that should do it. if at any point when you're trying to overclock the system refuses to power up, you've set the settings to aggressively and you'll have to reset the cmos. don't panic. this happens. it's not a big deal. we've all had to do it. this however is when you'll need to open your computer and switch a jumper the location of which is on page 28 of the second .pdf document in the manual. simply turn off your system. unplug it from the wall. find the cmos jumper (it's labelled) and move the jumper off of pins 1-2 and put it back on 2-3. leave it there for ten seconds then movie it back to 1-2. plug your system back in and turn it on and you should be back up and running. this clears any custom settings you've made in the bios so you'll have to go back in there again and reselect whatever you want.
that's about all i've got to say. most everything was in the manual. if what i've said freaks you out, than i'd recommend not overclocking. if you're afraid to get your hands dirty, then this isn't for you. if you still want to then great. read those anandtech articles on overclocking. they're instructive. post any more questions here.
i'm off to vegas so someone else has to take over for me.
cheers!
