Am I doing something wrong? I am running a P5Q-SE2 & E5300, when I try to overclock, I switch my FSB to 210 and the multi to 13.0X, the voltage is at 1.2000, the computer would not even boot with a 10FSB increase, I also tried doing 310 and the multi to 9.0X but it would not boot. Is it my cpu is there something else I need to do. Remember this is just a 10FSB increase.

Is it overclocking your ram?? Could be that your memory multiplier is set too high, and that pushes your ram beyond spec as soon as 200 is exceeded. If you have the option for 2.66 or 2 or something like that, then do it. You will be able to go higher then. I'm pretty sure this is your problem.

Say your fsb is 200, and the memory multi is set to 4. Then your ram will be clocked at its stock 800Mhz. But if your fsb increases to 210, and your mem multi is still 4, then your ram is trying to run at 840Mhz (40Mhz over stock) with no increase in voltage (unless you set that) and hence failing at those speeds.

I set my ram speed at auto, what do you recommend doing?
I set everything else aside on auto, I am looking to reach 3Ghz, thats about it.

I also left the northbridge auto, there are so many options. This wasn't there with my last AMD overclock. I'll read more into it.

Change your memory multi to its lowest possible (in bios of course) to start with. After you find a stable OC your happy with, you can try to OC the RAM. But before that, you need to get OC'd some. So set it low (like 2.00 or something close)

After that

You should try to manually set your voltages (mostly CPU or Core, or Vcore), increasing them slowly as you need to stabilize the system from failing (without exceeding 1.36v Core for you, since this is fairly new to ya).

----
Edit: I see now. An amd convert to intel guy. You'll probably get it quickly. To me AMD is more complicated to OC, since I've only messed with it very little.

Oh, and Northbridge voltage can pretty much be left alone in your case. You only want 3Ghz or so, so i can't imagine you would need to change that any. If you do, only increase it a little.

Set Vnb=1.2,manually select your ram speed and keep it as close as possible to 800.
Leave everything else on auto,including vcore and multi!!
Now raise your fsb and test!

Thanks, Managed to get 2.8 so far, left my ram at 1:2 , should I change it to 1:1?
I made the timings 5-5-5-15 & 800Mhz
Voltage at 1.2000, and I am about to test with intel burn test.

what kind of test should I run on Orthos ?

The ratio is important, but more of a fine-tuning to be done after you get around the OC you want. A 1:1 ratio is ideal, but hardly achievable without sacrificing the speed of your RAM. You wont really notice a difference except maybe in a Super PI run or something.

Without touching voltages you can get that CPU to run @ 3ghz

The problems this isn't working is possible ram malfunction or OCed ram like the gurus said.

I recommend. reseat the CPU one more time.

Without touching voltage you should be able to boot in @ 3ghz or 3.2ghz hope u get your problem solved,, gl,

Its good, My voltage is at stock settings, I have not touched it, on 2.9Ghz, testing in Orthos, temps are 42C Load and 25C Idle. Good?
I'll try to get 1:1, any tips tho on what I should set my ram to?

Right now I have it at 225 x13.0 , should I change the FSB and ratio to achieve a higher and stable oc?

But I also want to add that the heatsink is pressured against the cpu since the brackets were a little bit, I had to use a bit of force to fit the heatsink on but its all good. My temps are fine.

Heck, i saw the VID for that chip (sig) and i think you might be able to get 4ghz with the right voltages. Most of the e5x00 series chips will handle fsb speeds up to 333 and maybe farther with a slight increase in NB voltage and a core voltage around 1.36v (which is the highest VID intel will ship a chip with, hence deemed safe by OC'rs. But 1.45v is deemed max by intel's standards)

My current settings are 333 x 11.5 with voltage at 1.42 (1.45v set in bios). My starting VID was 1.26 tho, while yours was 1.1 or something. (you would need to make sure that memory multi is at its lowest i think. don't know that board well enough. other's do tho)

And yeah, temps are good as long as you stay around 60's C- low 70 C max
