Hey all,

As the title indicated I need help OCing my rig using easytune. I have never overclocked a system before so i dont wanna blow anything out my living room.

Any advice from ppl who have used EasyTune is very much appreciated.

Here are the specs:

Gigabyte GA-N650SLI-DS4 650i SLI
Core 2 Duo E6750 (B stepping, G0 revision)
EVGA 7600 GT
2 GB Buffalo
WD 250MB SATA HDD
Antec 900 Case
Antec TruePower Quattro 850 Watt

Again thank you in advance.

I tried using it but I feel more comfortable tweaking in the BIOS.

Ohhh, I see, is there a crash course thread on gigabyte BIOS on [H] for that?

I am pretty familiar but I am probably novice/advanced
 
I would use the BIOS as well. Easy Tune is OK, but software is not as reliable as the BIOS.

Advantage of software is not having to go in/out of the BIOS and restarting the computer after each adjustment.

There is a good tweaking guide discussing the Gigabyte P965 board by Bill Parrish in here somewhere. I would guess the BIOS is close enough to learn quite a bit from there and then figure out the rest yourself.

If you have questions after you read that, I'd be glad to help.

Initial steps will be the enable "host clock", disable "CIA", and slowly adjust the FSB upward. You may need to add or increase VCore.
If I recall this stuff is found under "MIT" in the BIOS.

Download Orthos, CoreTemp and CPU-z to aid in your evaluations.
 
Hmm Nvida chipset, I am not up on the details. This guide is for the 650's big brother but much should be the same. Worth a read just to get feet wet with the bios and how it works and what settings are important. Dont think my guide will do you much good.

Easytune is fairly easy to use but is limited in its abilities. For instance it cannot change ram timings, ram speed yes, timings no. Voltage adjustments are also lacking.

What magoo said.

set your memory timings properly in the bios. The "auto" settings typically are NOT the high performacne ones advertised by your ram manuf. would be the first step. Actually, despite having messed with this stuff for over 30 years my advice would be to do what I do with a new board. I read the manual 3 times, bios section maybe more and make marks next to items I dont understand (manuals can be awfull in their descriptions of what things do) and then google the items with unclear descriptions etc. It really really pays to know what settings are in the bios and what they do. Once you have that, any OCing guide can be used as a reference and you can adapt it to your board.

what I do (basically)

set the memory timings loose (5 5 5 18) with the lowest memory mulitplier (1:1) and raise the fsb in increments until the cpu craps out (will not boot into a copy of memtest86+ in the CD drive or has errors in running the first 3 fast tests.)

raise the Vcore cpu voltage some and see how much more, if any, that buys me.

record the max FSB and cpu multiplier setting and the resulting speed.

set the cpu loose, lowest mulitplier so it runs slow and is out of the picuture.
set memory at manuf advertised timings and memory voltage, do the same thing, increment the FSB, see where booting into memtest fails or memtests first 3 tests show a failure/error.

record the memory timings and voltage and FSB

leaving the cpu alone looosen memory timings to like 5 5 5 15 and redo the memory speed testing, you should end up with a higher number, typically much higher.

now you know what the cpu will do and what the memory will do tight and loose.

If the cpu has the lowest max FSB number you are pretty much done, use a little less and try and find a memory mulitplier that runs your memory as close to the max values obtained in testing memory, you have to decide if you want to run loose timings at a higher memory speed or tight ones at a lower speed. That is were a benchmark progarm can help if the benchmark program does the same kind of thing you use the computer for.

Thats the basics of OCing. Other methods exist but thats the "old school" way. And that is only a basic run, lots of tricks etc can be done. But the basic information above HAS to be determined, one way or another, in a methodical manner, or you just changing stuff and hoping something good happens. imo.
 
thanks bill and magoo, once i get home ill be messing around with it

thanks
 
I looked up your board on Gigabyte support.

The nvidia OC guide referenced already will be a great guide to get you started. Your BIOS is very close to that in the nvidia guide.

Your two BIOS sections will be advanced and MIT, in advanced you will disable some of the CPU protection and idle mechanisms that will interefere with OC.
In MIT you'll adjust FSB, FSB:memory ratios, and voltages.
Advanced memory settings require you to hit CTRL+F1.

I have a 680i board from ASUS and OC it was very easy. I just followed the nvidia OC guide.:D
