So I got everything hooked up. The computer is up and running. I tried searching all night and couldn't find anything solid that I could grasp and fully comprehend. Still a bit technical for me..

So here's what I have..
P5N-E SLI w/ E4300 (latest BIOS update)
2GB of DDR2 675 (PC2 5400)
Proper air cooling in place

Here's what I have currently setup in bios..

(ADVANCED- JumperFree Config.)

AI Tuning: manual
Voltage Control- VCore Voltage: Auto <------When and do I need to change this?

FSB+Memory Config section

FSB- Memory Clock Mode: Unlinked

FSB (QDR) MHz ----> ??? What do I enter here? Default was 800 iirc. Do I just increase it from 800? In what increments? Do I put in 805, 810..?

(Chipset)
Spread Spectrum Control
CPU and PCIE: Disabled

Are there any other settings I need to change?

So from here, what steps do I take? I want to be around 3GHz or a bit less ~2.8

Thanks. I'm trying really hard to learn by reading but I need a little guidance.
 
Yeah, you've got the basics of it. With the e4300 just increase the fsb until you hit a wall where it isnt stable. Make sure the whole time however that your ram speed is near what stock is and that your temps don't get too high. You might have to increase the vcore on it once you get too high, but I'm not familiar with the e4300 chips to know what their limits are.
 
I think I'm hitting a brick wall. I can't get past these settings in bios.

FSB (QDR) MHz: 1099
Vcore: 1.325

Increasing Vcore and FSB doesn't allow it to boot.

According to CPU-Z here's what I have..

CPU
core speed- 2463.5 MHz
multiplier- x 9.0
bus speed- 273.7 MHz
rated FSB- 1095 MHz

MEMORY
Freq- 328.5 MHz
FSB:DRAM- 5:6
CAS# Latency- 5.0 clocks
RAS# to CAS# delay- 5 clocks
RAS# precharge- 5 clocks
Cycle time- 31 clocks
Bank cycle time- 19 clocks
Command rate- 2T

So am I at the end of the line? What else can I adjust?
 
I did some tweaking with the memory voltage and Vcore. I'll update once I get word that it's stable. I'm at 3.1 MHz. I got it to 3.6 earlier but decided to back off. Not sure how stable it was. Now I have my eye on the temps through Everest.
 
Update..

OCCT latest version is showing Stable on the 30 min test.

My temps according to Everest during the test seemed pretty cool.

Idle: 99&#37; load
M/B- 31 C 31
CPU- 23 24
Aux- 34 45
GPU- 36 36
HDD- 26 29

BIOS temps post OCCT..
M/B- 31
CPU- 37

Time to do overnight testing with Prime or Orthos. I'll report back.

What voltage are you at for 3.1Ghz? or are you letting the bios handle it?
 
You shouldn't leave vcore on auto. It seems like most boards today (at least p5b and a few others I've read about) will increase vcore like mad by itself with an overclock. For example, for my e6400 to hit 3.2, I only need stock 1.325v. However, if I keep it at auto, it'll give the cpu 1.60v. Grr

Word man. First thing I do after achieving my overclock is try and ratchet down the vcore. The proc will run cooler with less voltage and last longer and more stable then with the higher voltage.
 
Wow you got 3.1 with this combo... this is the same combo i have can you please post ALL of your final settings???
 
Do you have your memory unlinked?

Anyhow, I'm up to 3375 on my 4300 w 2 GB (2x1) ShikaRAM DDR2 800 5-5-5-15 TRC 23, 8800GTS

CPUZ says:

FSB 1500
Multiplier x 9
Bus speed 375

Mem freq 400

PC's been on all day, played Oblivion for about an hour. I'm not sure what my temps are, I'm using speedfan and can't place all the values. None of them seem high though.

Temp1 34
Temp2 39
Temp3 25
Core0 27
Core1 28

I've set my Vcore to the 1.5 and the NB closest to 1.5. Everything seems happy overall. I've got a 9700 cooler. Nothing on the NB yet.
 
375 bus should have your rams running at 450fsb not 400...... have you tried running them 1:1?
 
According to CPUZ they're running 15:16. I'm quite a newbie at the whole C2D OC thing. My last Intel CPU (and only briefly) was a Celeron 300A.
