Need help overclocking E6500 Processor(all advice welcome)

post #1 of 11
Thread Starter 
Hi im a little new to overclocking but im not a noob. I want some advice to help overclock my rig to 4ghz. So far i have got it to 3.8ghz from 2.93ghz so i think that is pretty good. i know there is more i can do to the timings of my ram manually im still using auto on the timings. the highest ive had the fsb is 344, so please any and all advice accepted. here are my snapshots in cpu-z and my temps while running the torture test with prime95. system is stable and has never crashed .biggrin.gif:cheers:cheers.gif

First you're running 45nm CPU and that Vcore is allready over what I would consider SAFE for 24/7 usage..

And 2nd you're running a G41 motherboard that are been known as poor OCers..

Stick with what you have right now as on that mobo it would be very hard to do any better than you've allready have..

CHEERS..

I suggest you start by filling up your specs here

Next, You are running your memory at 860 MHz (430 MHz x 2) CL 5, when it is rated 800 MHz CL5.

As you may not know if you reached your CPU maximum, I suggest you change the DRAM frequency to 667 MHz. As it overclocked, it will result in 717 Mhz (2 x 358 MHz).

With this "lower settings" on your RAM, you will be able to find the CPU's max frequency.

Once you reach you max CPU speed, you can come back and see if your RAM can make it at higher speed.

Just a precaution note:
- Beware of the AUTO settings. I suggest you switch voltages to Manual and increase with cuation, within your cpu, NB and RAM safe limits.
- Beware of the CPU temperature

How are you testing stability?

Good luck with your overclock !

so I can only lower it to 860 and the more I raise the fsb it gives me higher frequencies. I can change the timings will that lower my ram speeds and if so what should I change the timings to, so I can achieve 667 dram freq??

I see, you are right: You are 29% above standard FSB, so 667 MHz (slowset available config) x 1.29 = 860 MHz.

In that case, yes, try loosening the timings: I recommend you to try 6,6,6,18.

In Prime 95, you can test "small FFT (In place)" which will test more CPU than RAM. You can also run the "blend", which will test the hole system (CPU - NB - RAM).

Knowing in which test fails narrows the fixes.

okay so if i lower my timings to 6-6-6-18 which clocks do i change cause this motherboard has every clock for the ram and im not sure which ones to change. when i do that should i up the ram voltage from 1.8. okay i changed my timings to 6,6,6,18 and the computer boots up amd is stable but i cant go to 345 from 344 fsb or it wont boot. so i have one question would my pc be faster with 6,6,6,18 timings or with 5,5,5,15 timings instead? my fsb is still at 344 and stable so what would be my best timings higher or lower? also if i added ddr3 ram could i get a higher overclock?

At the same speed, lower timings (5,5,5,15) is faster than 6,6,6,18.

I guess you mean that you can't go from 344 to 345, not the other way around.

If it boots 344 FSB and it does not 345, even with 6,6,6,18, then your wall is based either on the cpu or the NB or simply the motherboard.

Are you running on Intel's stock cooler?
If you reduce the CPU voltage, is it still stable?
Are you setting the cpu (Vcore) manually, or is it in Auto?
What's your NB (Northbridge) voltage?
Have you tried to increase NB voltage?

Try running OCCT Linpack test and report temperatures. I am worried about your CPU at that voltage...

okay i tried to run the occt linpack test for only ten minutes and after about 4min it said error here are my results. occt says my vcore is at 1.50, 3.3V at 3.33, 5V at 4.75, and 12V at 12.94. temps went up to 66 when cpu was testing at 100%.
