Core 2 E6300 overclocking problems

[alcatraz678]

Hi all,

I've been overclocking my system since Monday but I still couldn't get some good results. I only reached 2450 MHz on E6300. My system setup is this:

GigaByte GA-965P-DS3 - F7 BIOS
Core 2 E6300
Kingston 1GB PC6400 DDR2 800MHz 4-4-4-12
750W PSU


I followed wuss's instructions about overclocking the Core 2 Duo, but I really couldn't achieve a higher CPU speed.

I gradually increased the FSB by 5 then reboot my computer , but then the computer would reset by itself.. Then I increased the CPU voltage slowly then tried to boot up my computer again, but the result was still the same.

Then sometimes I get a problem of Microsoft XP system file is missing, then I need to repair the Microsoft again by using the DVD. Have you encounter this yet?

I want to reach 3.0GHz please anyone teach me some techniques that overclockers use to reach their maximum point.

I had that problem yesterday with the rebooting. An increase of the DRAM Voltage solved that problem. But then, mine is a DDR675 ram, yours a DDR800, so I'm not sure.

Besides, make sure you have your Memory Multiplier at 2.0 for now. Because when your mobo detects your ram initially, it might set it to run at 800MHz at 266MHz FSB (3.0x Multiplier). At 2450MHz, you're running on 350MHz FSB, and your ram might be running on 1050MHz, which is ove 250MHz above your stock rating.

Yes, I have done that settings. So what do you usually do if your system hangs in the desktop? Do you just adjust the CPU voltage until it fits?

For your case, if you're set on 1:1, I don't think your RAM is your limiting factor.

It's most probably your Vcore that's limiting you, try increasing it till it's stable.

And remember to have your PCIe Frequency set at 100MHz, and your PCI Frequency set at 33MHz.

And when you attempt to torture it, observe the Vcore reading on SpeedFan, if it's fluctuating a lot (more than 0.07-0.10), you might have problem with your power supply.

Anyway, what's your temperature readings?

my temperature readings are Temp1:37C Temp2:30C @ idle mode while in torture mode Temp1:41C Temp2:39C running @ only 352 FSB x 7

In that case, it's most probably your Vcore.

Might even be your Vdimm.

Try increasing your Vdimm to 2.1/2.2V, just lower it down when your system is stable at your desired/maximum overclocked speed later on.

Then check if it's stable, if not, then increase your Vcore till it's stable.

can i increase the Vcore as much as I can? because I'm quite afraid that my cpu might overheat. What about the Vdimm? Can I reach +0.6 upon?

I tried to do what you had told me, but still no success at all. My computer keep reseting during post. I had reached 1.45v but still got the same issue.

I personally wouldn't increase the Vdimm by more than 0.3/0.4V as it'd cause electron migration.

1.45V is a bit high for C2D's Vcore, I don't think your Vcore is the problem now.

Your PSU, 750W, of what brand? Is it a reliable one? Coz that might be the problem. There shouldn't be any problem with your setting requiring that much wattage, but then, a bad quality PSU is most likely to cause problems.

As far as I can see, your mobo/ram/cpu/temp aren't the main issue.

Try replacing the PSU with any PSU you've got in hand, from your currect pc or whatever, and see if there's any difference? Besides that, REMEMBER to lower your Vcore. At 1.325V, I think you can easily hit above 3GHz, as I achieved mine with 1.275.

oh sorry sorry, i only have 650w PSU.. LOL, I thought I have 750w.. The brand is silverstone. i'll just try to buy a new memory, maybe corsair branded. kingston sucks..

Don't Gigabyte boards reset once after OCing? Do you let it boot back into windows? I may have misunderstood something...

Hehe the fun starts at vDIMM 2.6v and vCORE 1.6v
The voltages is wusys guide are 24/7 safe and the system will last a very long while like that.
