First of all Im a noob talking about OC. So that said, i would know if you guys can help me with something that came up to my mind.
Im buying an ASUS MoBo that as far as i know, come with some feature to OC the cpu, i dunno if you can o.c. anything else besides that. So the question here is... should I use that or better look into a "step by step" guide (if there is) to O.C. the cpu?
Gigabyte motherboards have really nice overclocking features man. I think I have said this on a few threads, but you have to be carefull. Some of the cheaper ASUS boards have limited features for voltage tweaking, which can cause major problems when going for the higher OCs. Im using an AsRock motherboard, and it does have some features for twealing voltages, but its not as stable as the two Gigabyte motherboards I use at work. AsRock mobo also suffers from "FSB droop" (the clocks I set in the BIOS always appear lower on CPUz for example in Windows), but it was good VFM. But seriously, try a Gigabyte board. They all seem to have the dualBIOS feature as well, which means that when you fail an overclock, you never have to reset your motherboard using jumpers.
Gigabyte boards are most likely better and dual bios could save your system if it won't post. But I have never experienced FSB droop on my board or my brothers super cheep Asrock board (£36) and the overclocking features are all you need in my 880G (my brothers has vary large voltage increments but otherwise OK). I would say get the gigabyte if you can afford the extra and its not much more but there's nothing wrong with the Asrock ones.
As for the guide I read it already but still Im a little worried about crippling it or even something worst. Thats why i wanted to start using the applications that come with the mobos, since as far as ive seen they show you what they are changing.
About the boards, Ive had gigabyte boards and they are very good too but never have had problems with asus also, and talking about asrock i havent but heard nice comments about them.
So my question here is then, should I use first the application (or even better, should i use it xD) or you guys suggest me to go straight to bios?
About the video card, im planing on getting the 5770 since I cant afford more than what it cost XD.. even if im getting the asrock (with 2 pcie 16x, 8x8x) or the asus (1pcie only). If i get asrock ill get another 5770 in 5-6 months to xfire since ive heard 5770x2 do almost as good as 1 5870 or am I wrong?
My Asrock board comes with both AMD overdrive (don't use this for overclocking if you want it to work) and a more useful Asrock overclocking program which basically allows you to change things without going into the bios every time but occasionally reports crazy settings. But really you want to be using the bios if you keep an eye on the temperatures and don't use over 1.5V core voltage you shouldn't fry anything. If you are rally not confident only use the multiplier and core voltage and you should still get good results. I was surprised when I saw this http://www.tomshardware.co.uk/charts/gaming-graphics-ca... showing that as you said 2 x 5770s is better than a 5870 and even more surprised that my 2 x 4870s is even better.
Then i should just not move ANYTHING but the multiplier, in some of the post they said i have to change to manual to oc and move the voltage but since i dont wanna move but the multiplier i guess this isnt for me am i right?, I really dont wanna fry it by mistake XD, and ive read a lot of post about O.C. on amd and so far ive seen that with 18.5 as a mult. will get you a 3.7Ghz without moving voltage.
Another thing then comes to me. Should i use a new cooler or keep the one that comes with?
read as much as you can.. but also.. just take a trip to youtube.. theyll walk you through step by step.. personally i use amd overdrive and turbo v.. i can overclock my phenom x4 955 3.2 (stock) to 4.. not comfortable with that tho.. 3.8 or 3.6 im happy with.. it literally takes you 20 seconds to do it.. increase the multiplier and apply.. if it crashes its no good.. your pc will restart and its back to finding a stable clock.. you may have to increase the voltage which makes the cpu hotter.. i dont recommend that.. no use in messing up your system.. watch some you tube..
Coolers are pretty cheap and necessary if you're going to raise the voltage. Don't worry about frying your CPU unless your significantly raising the voltage. Most bios will not let your raise the voltage over a certain temperature.
