EP41-UD3L and RAM

[ranp101]

Hi everyone,
I have the Gigabyte EP41-UD3L (rev. 1.0) motherboard and I recently bought 2 RAM sticks.
I had 3GB of RAM before: An OCZ with 1GB and Kingston with 2GB.
It all worked fine until I plugged in the new sticks (Kingston with 2GB - From the support list of the motherboard and another OCZ with 1GB - same model as the old one),
I plugged them in like it says in the manual, and when I turned on the PC, I couldn't enter the BIOS settings cause the computer
went off 10 seconds later, I tried to switch between the sticks a few time but I got the same result.
What could be the problem?
thanks in advance (:

I would hazard a guess and say that having mismatched ram modules with different timings and probably different voltage requirements is most likely your problem. What I would do is grab 2x2 gigs of ram of the same breed (prob not OCZ) and try that.

Could you list exactly what ram modules you are trying to run?

Also did you clear your CMOS before swapping the memory sticks over?

If not do it now by following this guide.

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least ten minutes before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Opimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self and then press F10 to save and exit.

I've tried to use 2x2 gigs of ram, I turned on the computer, the BIOS recognized 4 gigs of ram,
but when the OS (windows 7) started, the computer suddenly shut down.
what should I do?

and the modules are:
2x Kingston KVR800D2N6 2G-SP
2x OCZ2SOE8002GK 1GB Dual CH

Dark Mantis,
I cleared the CMOS, and I keep getting the same problem.

Take out the OCZ stuff and try booting from the Kingston. The Kingston is 1.8v and that is what the bios default is.  The OCZ is 2.0v and has a different timing to the Kingston. Try that and let us know if you can get into bios.

I got into BIOS and I saw that all the 4GB (Kingston) are recognized, but when I tried to enter the OS (Windows 7) the computer restarts before the welcome screen

I would suggest downloading and running the following program.

Memtest86+        http://www.memtest.org/

Insert one stick of memory in slot 1 and run Memtest on it for at least 10 loops and if there are no errors then swap it over with the next one and continue untill you have checked all  modules.

If you have any errors the module is faulty.

If you have any faulty modules you will have to return the whole kit as they are matched.

Post back when you have done that with the results.

If memtest is all good, haveyou set the timings for your ram? If you have try upping the MCH Core to 1.200

Hi Dark Mantis,
I didn't found any faulty modules using Memtest86+,
but, I just noticed that the other 2GB module is OCZ OCZ2V8002G
and not the same as the newer one - Kingston KVR8002N6/2G
they both 800mhz, 1.8v.

I've tried to boot with one module at a time and it works fine,
but I can't boot when they're both installed.

any idea?

thank you again
 

[Dark Mantis]

You must have two modules of the same make and model to run together properly or as you are finding it gives problems. In fact ideally they should be a matched kit.

[ranp101]

oh I see...

so I'll need your help:
I need at least 6GB of RAM on my board (8GB if 6 is not possible),
you can help me found the right modules to do that?

thank you

Certainly, what is the revision number of your motherboard? You cna find it printed in white on the left hand side near the slots.

What do you expect to be using the system for mainly ?

[ranp101]

My Motherboard:  Gigabyte EP41-UD3L (rev. 1.0)

and my mainly use is video editing, so rendering is the issue

[Dark Mantis]

So basically you would be using a lot of RAM for the rendering then?

[ranp101]

yes, RAM is the main source for rendering
