im sorry guys its 680i mobo

hey guys its me again... (yes yes i no.. i ask tons of stupid questions.. sigh.. so thank you for your patience w/ me... despite my stupidity sometimes... )

i want to overclock the cpu n the memory n etc. can someone give me some clear idea what i should overclock (cpu... gpu.. and memory)?

oh what is FSB?

well the driver comes with Ntunes... despite my minimal knowledge of computer... i realize that this program makes tweaking a whole lot of easier since i can do it after i am logged on and all controls within my finger tips..

currently my bars are all the way to the left for

CPU core frequency
FSB Frequency
Memory Bus Frequency

i toyed around with it (never clicked apply) n dragged the bar all the way to the left and the CPU core frequency went from 2456 MHz to 5600 MHz...
FSB Frequency went from 1068 (QDR) Mhz to 2800 (QDR) Mhz oh.. wats QDR?
and lastly
Memory Bus Frequency went from 800 (DDR2) Mhz to 2100 (DDR2) Mhz.

umm whats a good setting?

n can someone explain to me what CPU, FSB, Memory Bus Frequency is too plz?
pretty plz? lol
 
FSB= Front Side Bus
QDR= Quad Data Rate
CPU= Central Processing Unit

Frequency is the speed that they run at (ie 2.4ghz is 2400 megahertz, a megahertz is one million hertz. 1 hertz means 1 cycle per second. So a cpu with a speed of 2.4 gigahertz is capable of 2.4 billion hertz per second)
 
We need to know the other parts you are using...

CPU
Video Card
Memory
CPU Cooler
HD
Power Supply

And don't touch anything, please!
 
oh ok.
umm heres my part

well as you already know.. i have a BFG Nforce 680i mobo.

2.13 ghz core 2 duo e6400

two 7950 GT OC (In SLI)

two gigs of XMS2 Corsair Memory

BFG 800 Watt PSU

320 Seagate SATA

and Six 20mm fans (its lik a AC in there...)

oh... i need help really... the system crashed on me once.. but the Ntunes doesnt make permanent changes n shuts down if u did something wrong..

i wanna overclock the system fairly high..
i have money to spare so this is like my practice...
this is my test comp in a sense.. since i got another rig with two 8800, 680i Mobo, Core 2 Duo E6600, two WD 150g Raptor, and 4 Gigs of Corsair XMS.

i wanna try it on here first n get comfortable with overclocking before i do the other one.

help me plz!
 
oh n how do you make the changes permanent? the stupid Ntunes Driver doesnt let me do that...
 
QDR= quad data rate. its intels method for running the front side bus(FSB). Stock is 266MHZ but since its quad pumped it equals 1066MHZ. I wouldnt try 2800MHZ right away as that is pretty much impossible. Take small steps when overclocking. You want to check stability. I dont know how to overclock on the 680i as I dont own it so I cant help you there. When you overclock your FSB your cpu is overclocked at the same time. You multiply the FSB times your multiplier which I think is 8. You also got to mess with voltages to help stabilize your overclock.

Your memory speed is double data rate. So 800Mhz is 400Mhz x2. 2100MHZ is pretty impossible since you would need ram to run at 1050MHZ x2. Your ram will be overclocked as well so you may need to loosen your timings to find your maximum overclock. Theres also dividers for ram but im not sure how they work on your mobo.

One word of advise is to be careful. It seems your pretty new at this so I dont think you want to fry your stuff so take small steps,and ask questions to double check and it should be fine. Hope I answered some of your questions and didnt confuse you.
 
What's the RAM speed? (you forgot that)

Don't use Ntune!

You need to get in the Bios. Press F2 or Delete when booting up.

This is an overclocking guide by Nvidia.. READ IT

http://www.nvidia.com/docs/CP/45121/nforce_680i_sli_overclocking.pdf

Basically, you could try disabling ALL SPECTRUM OR THROTTLE RELATED SETTINGS..

Disable C1E, SpeedStep, and Thermal Control

Set your FSB and RAM to "UNLINKED"

Set your FSB to 1600 or 400 and set your RAM to 800mhz (if you have 800mhz RAM)

Under RAM / Memory timings, enter the main 4 values advertised by the manufacturer (4-4-4-12, 5-5-5-15.....)

Under Voltages, leave all under AUTO except for the RAM Voltage. Again, set it to the Advertised voltage. Set the CPU Voltage to 1.38V.

1.5V is high
1.55V is very high
1.6V is too much

If this works, you'll have a 3.2ghz overclock.

Test your system with Orthos (download it, free) for at least 30 minutes (8 hours later)

If it passes, you could try lowering the CPU Voltage.

Watch your temperatures. Don't go over 60c during load.
 
thanks man. Ya.. i ntune frustrated me for awhile cuz nothign would work.. lol. k ill give that a try... i just got into computers n im having a blast. i built 4 rigs in the past 2 months.. im driving my parents crazy cuz they r just sitting there.. but i cant help it.. im completely hooked... ugh.. now im tweaking n messing around with overclocking n the fun meter increased three folds... omg.. someone help me.. lol i cant stop..
