[RAM problem] GA-G41MT-S2P (rev. 1.3)

[bouldega]

As the title says it all, i have ram problem with motherboard GA-G41MT-S2P (rev. 1.3).

My system specs:

[Processor]
Intel Celeron E3300 @ 2.50 Ghz

[Bios]
Latest version available > F3

[Windows]
Windows 7, 64 Bits

[PSU]
RetailPlus 465W

[Graphic card]
Gigabyte GTX650 OC edition

[Actual RAM]
Kingston dual kit 4Go (2x2go) 1333 Mhz

[RAM to install]
Kingston dual kit 8go (2x4go) 1333 Mhz

[The problem]
When I install the new ram, my bios won't post at all and I got no display (black screen), then after a minute or less, the computer restart by itself and do it again until I remove these ram and reinstall the old one.

[Solution tried]
1. Reseated the cpu > No change
2. Cleared CMOS > No change
3. Removed bios battery for about an hour > No change
4. Removed graphic cards and driver, used the onboard graphic > No change
5. Messed with bios setting for ram timings to match the new one > No change
6. Tried the new RAM on my friend's computer to verify if it was the RAM module > Ram module are perfect

I don't know what to do. The system don't recognize my new ram module (they are the same as my old one, but instead of 2go module, it's 4go module). Tried to get help from gigabyte expert on their support page, no positive results.

Thank for your help.

Have you tried just one stick of the 4gb. That CPU really only supports 800 memory. Maybe the CPU just can't handle all that memory at that speed.

I would try 1 - 2gb stick and a 4gb stick. I have read on here when you max out the memory it will not boot. Yes it says that it will support up to 8gb.

Why my cpu should not handle that speed when it perfectly handle my old one at 1333 Mhz... I will try one stick of 2go and one of 4go and post the result. Maybe the motherboard is too old to support new ram module... I don't know but worth a try.

Ok, tried it and no change. But I received a message from my bios when I entered it and it says:

THE SYSTEM HAS EXPERIENCED BOOT FAILURES BECAUSE OF OVERCLOCKING OR A CHANGE OF VOLTAGES.

Yes I under stand what you are saying about the memory. I have 1-gb & 2-gb sticks of Kingston memory. It does the same thing as what yours is doing. 

The only thing you can try is check the volts with the old ram. Most MB will set it like 1.8 I think. Change it to the right volts if it isn't right.

If it is right bump it up a little like if it is 1.8 change it to 1.9. Then reboot if it is fine. Then put in the new ram and see what happens
