Need help on how to adjust memory timings

I have a Gigabyte DS3P rev 3.3 with the latest BIOS. I can overclock to 3.2Ghz with no problems at stock volts for everything including default memory timings.

But I am wanting to overclock some more because at 3.3ghz my PC fails when I test the CPU after 2mins with ORTHOS program.

How Do I adjust my memory timings to make them lower. I use Geil DDR2 PC8000 1000Mhz CAS of 5-5-5-15.

If I lower the values to 6-6-6-16 pc boots then powers down straight away!
 
I dont think you will be able to tighting your timmings on that Memory to be honest. Then again you moght get lucky.

Im not sure how the BIOS is laid out on that Gigabyte board but its most likely simial from one board to another.

So go into the BIOS and see if you can find North Bridge Settings. Should be under their.

Anyway, your memory shouldent be holding your overclock back.

What are you running your FSB at and Multiplier?
 
If anyone else can give some info here.

I don't want to tighten my timings as mentioned in the post above. I want to lower them to increase the FSB. I'm basically after the way to do this. :)

I am running at 370x9.

I understand memory timings do hold an overclock back - correct me if i'm wrong.
 
if you are at 370x9, then drop the ram divider, at 1:1 divider you could run the FSB at 500Mhz without having to overclock the ram.

Like i said if you want to tighting your timmings up go into the North Bridge settings, thats where they are most likely locoted.

Anyway your getting slightly confused i belive. I think you mean the Memory Frequency.

As you said your FSB is running at 370, so set your Memory so its running at 740MHZ (DDR2)

Now you should be able to keep raising the FSB.

PCI express frequency is at 100 and system memory multiplier is at 2:00, should it be at 1:00? :)

I highly suggest reading an overclocking guide. :)

I have followed the DS3P overclocking guide. I just want to lower my timings for the RAM to see if that helps.

I have a E6600
 
Ok start again.

First of all go into your Bios and disable everything that may hinder the overclock. So Speedstep, Speed Spectrum and C1E Support.

Also lock the PCI-E Frequency at 100 and set the PCI Clock synchronization mode at 33.33MHZ.

Now set your Memory Timings as 5-5-5-18 and Memory frequency at 533MHZ (so 1:1 ratio with your FSB (which will be 266 for your E6600). By having your memory timings very loose this will eliminate the RAM if say for instance your system becomes unstable. Manually set the stated manufacturers memory voltage aswell. (Memory timmings make very little diffrence to the performance)

Also make sure the multiplier is set to 9.

Set the CPU Vcore voltage to 1.325 (i believe thats the stock voltage for that CPU)

Now just raise the FSB by 5-10 at a time. If it fails to boot, up the Vcore a bit.

I would personally run Orthos for 30mins or so once i have reached an FSB of 375.

Note:

FSB termination Voltage useful option when pushing the FSB frequency high on the CPU, adding a little voltage here can help stabalise things as you clock higher.

NB Vcore Remember the memory controller is on the NorthBridge, adding some voltage here can have a huge impact on how well the CPU and memory overclock.

SB Vcore useful for adding extra voltage to the PCIE bus when overclcoking video cards and trying to run them on an overclocked PCIE frequency.

When you boot up and enter BIOS setting press CTRL + F1 and that will show all the bios options.

When you go into the setup page for voltages you will now have all the memory timing options available to you.I'm not sure it's the RAM holding you up though. I've got Geil RAM like yours and I can easily get it up to 900+MHz.

It does get upset at 1000 + though.

Rather than having the motherboard set at AUTO for your RAM timings go and set the manually as per your RAM speeds

Clocking the gonads of the RAM won't make as huge a difference as you might think especially if it's holding down the speed you can clock the CPU at.

Clock the RAM multiplier at 2.00 and see how you get on

What processor do you have and what voltages are you running at.

e6600 stock volts. :)
 
3.2 at stock volts is very good.

Bump up the CPU Voltage by a click or two and then start slowly increasing the FSB and see how you get on. What are you using to cool the CPU.

You might also want to add 1 click to (G) MCH and FSB voltages.

Ok the highest i can go is 370x9 then it crashes in CPU test. I'll adjust the voltage for that MCH. :cool:
 
It could be that it's as far as your setup will reach.

When I had an E6600 on a Rev 1.0 DS3 I had the (G)MCH at +.3V and the FSB at +.2V.

I could run at 3.35 but it was a bit toastie for my liking as I had to step the CPU voltage up a fair bit.
