I own a old Foxconn G31MX MoBo and i saw in the BIOS that i can OC my CPU. And i did it :pt1cable:. There were 5 options to choose :
Auto
Step 1 - CPU Clock 210MHz ; CPU Voltage Regulator 0,0500V ; DRAM Voltage Regulator 0,10V
Step 2 - CPU Clock 220MHz ; CPU Voltage Regulator 0,1000V ; DRAM Voltage Regulator 0,20V
Step 3 - CPU Clock 230MHz ; CPU Voltage Regulator 0,1500V ; DRAM Voltage Regulator 0,30V
Manual
I noticed that there is an algorithm ( when you rise the Clock with +10MHz you have to rise the Voltage Regulators with +0,05V, respectively +0,10V
The problem is that the DRAM Voltage Regulator is max. 0,30V
Atm i use the Manual option and i set the Clock to 240MHz, CPU Voltage Reg. 0,2000V and the DRAM Voltage Reg. to 0,30V
There is another feature called Spread Spectrum but i have no idea what's good for.
With my configuration i got a 500MHz Boost and the CPU is running now at a speed of 3.0GHz, but i'd like to go further and get even more cuz i checked the Temperature of the CPU during playing some high-end games and the max was 67°C with the stock cooler... And before overclocking it was going up to 62-63°C so it's not a big difference and it really worth to get a 500MHz Boost for only 4°C...
What i want you to do is to tell me what's the best configuration ( CPU Clock / CPU Voltage Regulator / DRAM Voltage Regulator ) to get the highest Clock.
And also what's Spread Spectrum good for.
And i also noticed that sometimes, after overclocking, the computer freezes when the Windows is starting ( i use W7 and for the ones who use the same it freezes when the 4 bubbles ( Windows Logo ) appear when you turn on the computer ).

Thanks in advance ;).

Edit : I forgot to say that the max CPU Voltage Regulator is 0,2500V and the max CPU Clock is 600MHz ! :ouch:
I did some maths and if i somehow manage to set the CPU Clock at 600MHz i get a 7280MHz Boost... That means my CPU will run at a speed of 9,780GHz :love: Impossible though... :heink:

I'd say you're good right where you are. You have a decent OC at 3Ghz that is probably fine for your GTX 750, anything faster probably isn't going to significantly increase your FPS anyhow, and even if it would it's irrelevant as you've likely reached your plateau for that chip in any case. 500Mhz is a nice bump up and your temps are within spec, although a bit lower would be nice. Installing a GOOD aftermarket cooler might help quite a bit with that part of the equation. If you're using the stock cooler I'd seriously consider upgrading. I probably wouldn't change your settings at all from where they are now if it passes stability testing.

Spread spectrum is for stability, supposedly, I disable it.

If your rig is freezing during boot that means it's not stable and you need to back your overclock off a bit. Nobody can tell you what "settings" are right for your rig as every chip is different and depends entirely on the individual chip, motherboard, power supply (Which by the way, if you have a cheap PSU you may be having issues with your overclock strictly due to this) and of course your BIOS settings and cooling solution. Your temps seem a bit high but acceptable. More than likely though, you don't have the voltage set high enough to keep your OC stable and adding more voltage is going to increase the amount of heat, which you don't want with temps that are already where they are during normal use.

To get an accurate picture of your overclock, you need to run Prime95 on small FFTs. Run it for ten minutes to verify thermal response. Run it for 24 hours to verify stability. If the temps go past 70°C stop the test. If the Prime run errors out and stops on it's own during the 24 hr run, the OC is NOT stable and needs to be backed off or apply more voltage.

If you are using the stock CPU fan, return your settings to default and stop overclocking. You need a good aftermarket cooler to overclock ANY configuration. There are NO stock coolers, aside from maybe a few newer CPU's that come with liquid cooling, that are capable of performing at a level that will allow you to overclock to any realistic degree. The games your are playing, or any games for that matter, are NOT a good indicator of stability OR heat where your overclock is concerned. You HAVE to run a stress test utility like Prime95, Intel burn test, OCCT or something similar, with Prime95 being the method of choice, to verify that the temps and stability are ok.

thx for help but i already wrote my MoBo ( Foxconn G31mX ) and my PSU is a iNTEX Smart Switching Mode Power Supply Enhanced Pentium 4 ATX2.03 450 Watt
I did a intel burn test and the max temp didn't pass 70°C so i guess i can add a few Volts so i wont get more than 74-75 and that's what i was looking for - if i change the CPU Clock to 250/260 what CPU Voltage Regulator value should i use ?
I understood and i already know that i don't own a MoBo and a PSU and a Cooler made for OCing but i doubt that i will kill my computer by adding some MHz to the CPUs speed...
I will also post you a DxDiag to let you know all that you want to :

No, 70°C is the MAX temp you ever want that CPU to be at, according to the Intel website. More than that and you are likely to fry the chip.

That's so funny, really. Adding some Mhz to the CPU's speed is EXACTLY what causes it to burn out, when you start overreaching beyond what the chip is capable of, especially when you DO NOT have sufficient cooling. It's pretty clear to me that you're going to do whatever you want anyhow, so have fun with it for the few days you have before it burns up.

What answer were you waiting for? If you were waiting for advice on how to gain an even bigger OC, that's not going to be forthcoming as, in my opinion, with your temps where they are now, it would not be advisable to OC further. Perhaps after you get a better cooler, if that brings your temps down any, it might be possible to gain a little more performance but as it stands, I wouldn't push it any further.
