Hi Guys,

I just got new RAM because I wanted to upgrade from 2 to 4gb. It's Kingston HyperX PC2 - 8500 CL5 1066 mhz.

You can see my system specs below. The FSB is at 450 mhz, so setting the multiplier to 2.4 will get 1080mhz. It should be able to do 1066 right? I'm getting blue screens though. I read something about voltage, should I raise the voltage? I tried + 0.1 and + 0.2, but no luck. Do I need to raise it further?

Have you manualy set your timings to there rated settings?

Have you set your ram voltage to its rated voltage?

When increasing the voltage what do you mean? On your ram or CPU?

Yes try to increase your voltages. The BIOS default voltage to the RAM are often lower then what the RAMs rated voltages are. HyperX are set to run at 2.2V, what are your current voltages?

My CPU voltage is 1.4000v. I don't know the voltage of my RAM, I can only choose +0.1 - +0.6. Where can I find my current RAM voltage?

I set the timings to auto, It sets it to 5-5-5-18.

I did some googling, I think it's on 1.8v. So I need to set it to +0.4 in order to run it at 1066mhz / 1080mhz?

Do you have Everest? That will show you your current RAM voltage or check in the PC Health screen in your bios. Then up the voltage as required.

Could you post a link to your ram.

Ok, so I tried setting it to +0.4v and set the mhz to 1080. Windows wouldn't boot.

Then I lowerd FSB to 444, so memory is set to 1066mhz @ 2.2v, windows boots but orthos displays errors.

I can see in the specs of kingston that memory has been tested at 2.2 - 2.3 v.
Can I safely set it to +0.5? Even though it's red blinking in the bios?

The timings for those RAM should 5-5-5-15 and your voltages should be located in the M.B Intelligent Tweaker inside your BIOS... How did you increase the voltages if you don't know where they're located?

Have you run memtest86? I donno if this could be caused by faulty RAM, but maybe it's worth the try..
And it's safe to pump some extra 0.5 volts into it, just make sure the RAM doesn't get too hot.

Ok I'm confused now, at the health status it says ddr2 / ddr3 voltage: 2.000v at default.

When I put it to +0.3 it says something like 2.27v.
So default voltage is 2.0 volts?

But when I look in the gigabyte easy tune utility (windows), standard voltage is 1.8v and when I set it to +0.3 it displays 2.1v

.

It works perfectly stable at 800mhz 5-5-5-18 stock voltage, as said in the manual, so I don't think it's defective.

Should I up it to + 0.5v? or does this mean it will become 2.5v?

Ok let me get this straight. You are running 4x1GB memory? This means that it causes quite some strain on the mobo, using 2 sticks (2x2GB) is better.

Alright but now you just have to work with what you got, that means you are going to need to increase the NB/MCH voltage or else you can't get 4 sticks stable at 1066mhz.

Use these settings:
NB/MCH voltage - 1.3v (+0.1)
Memory timings - 5-5-5-15
Memory voltage - 2.15v (+0.35)

Those modules you got all have Micron D9 chips and are sensetive to heat and voltage, I suggest you do not raise the voltage higher then 2.2 - 2.25v.

Last but not least, could you check if those Crucial Ballistix modules you got are double sided? If they are single sided then it's no wonder you can't get 1066mhz stable.

No those are my old ones.

Currently I'm running 2x 2gb Kingston hyperX pc2-8500 1066mhz. (see first post).

But to get this straight, you're saying stock voltage is 1.8v? Even if health status says 2.0v?
