Need help on how to adjust memory timings

Warpy · 10 Aug 2007 at 10:56

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!

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.

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

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.

I'm not sure how to do this? :confused:

What CPU have you got?

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

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:
