BSOD with both sticks memory in

I recently built my first computer. I immediately started encountering problems installing vista, and i got a bluescreen twice! during the vista install. I removed 1 stick of memory and got through the install fine. Now whenever I have both sticks in, I bluescreen pretty quickly. I have memtested each stick individually in the first memory slot for 9 hours each and each received 0 errors, however when they are in together, after about 40 seconds or so memtest gets errors and stops running.

This is my build http://secure.newegg.com/WishList/PublicWishDetail.aspx...
Intel E7400, Gigabyte EP43-UD3L and 4GB G.Skill RAM

I am thinking it is a problem with the motherboard? What do you guys think?

Did you manually set the speed to 1066 MHz, 5-6-6-18 timings and 2.0V? If it's unstable, try 800 MHz and go from there. Always bear in mind that 1066 MHz memory is overclocked 800 MHz memory that should work at a higher frequency.

I have not manually changed any of the memory settings, they are at 5-6-6-18 1066mhz automatically with the voltage at about 2.0 to 2.05 volts
I have also not overclocked the cpu or anything else in the rig.

That normally doesn't happen automatically because 1066 MHz is not a JEDEC standard. If you are running the memory at 1066 MHz, then your memory is overclocked.

Well it goes to 1066 automatically in my motherboard, so I guess that means its factory overclocked because I certainly didn't do it. I paid for 1066 ram, and I should be able to run it at 1066 without any problems.

Also I don't know if this matters, but each time I blue screen it's a different code. I've gotten 4E, 3B, 50, A, D3, 7F, Fe, DT, 3B, 1A lol
The fact that each stick passed memtest in the first slot makes me think its a mobo problem and not a ram problem but I'm no expert

You paid $1 more for 1066 MHz memory. The same memory rated at 800 MHz (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) can be run at tighter timings and it requires less voltage.

Try the RAM at 800 MHz to determine if it's stable. Your system detected it at 1066 because the EPP profile is enabled in the BIOS. Gigabyte or any other manufacturer can't guarantee perfect stability with 1066 MHz RAM. If you absolutely need to run the memory at 1066 MHz, you could try http://www.newegg.com/Product/Product.aspx?Item=N82E168....

I changed it to 800 mhz eventually, was hard for me to figure out in the bios how to do it because it was kind of confusing to me, and set the timings to 5-5-5-15 with 2.0 volts and it seems to be running well. Memtested for 2 hours and got no errors.
To get it to 800mhz I changed the MCH Frequency latch to 266 MHz and the system memory multiplier to 3.00A. Is that how one is supposed to do it? lol

Do u think I could make the timings lower at 800? Or would there be no real point.

Use CPU-Z. The Memory tab displays the current frequency (it should be 400 MHz) and timings. The SPD tab lists the timings and voltage for each of the supported frequencies. You might be able to run more aggressive timings at 800 MHz and still have a stable system, particularly at 2.0V.

Hmm tried putting it to 4-4-4-12, yes ambitious, and now the computer gets stuck on the gigabyte screen and when I hit delete to get into the bios to change it nothing happens. It eventually powers off and then back on again without loading vista. What do I do?

Nvm, figured out how to clear cmos. I think 5-5-5-15 is as low as I'm gonna go. I'm still gonna ask on the G.skill forums whether the memory should be able to be run at 1066 with my motherboard and maybe I'll rma it, but I'll have to see.

Also, in CPU-Z, under SPD the JEDEC #2 is 400 MHz at 5-5-5-15 at 1.8 volts, should I change mine from 2.0 to 1.8 volts?

You can run them at 1.8V-1.9V. There's nothing wrong with your motherboard. Few people run into issues with 800 MHz memory, but there are lots of posts about issues with 1066 MHz modules. The performance difference isn't worth it.

run memtest to see btw you migth want a CD R boot the PC of the CD than see if there is a problem with ram btw you NEED to run two one with it at 800Mhz and one at 1066

if you brought 1066RAM it should run at it without problem at its stated voltage and timings

They should run at 1066 MHz only if certified for that motherboard. I still can't figure out why so many people believe that DDR2 1066 MHz memory will make their system much faster than 800 MHz memory.

the mobo needs to be compatible with the moduls yes, but the RAM should be able to run at 1066 on any compatible DDR2 mobo without a problem, I dealt its the mobo it could be just a fact that the mobo isnt compatible with them in both slots. easy enough flash the damm thing problem sorted

I think you need to update the BIOS from Gigabyte's website

Here's How to do it:-
1-Open this link ( http://www.gigabyte.com.tw/Products/Motherboard/Product... ) & select the BIOS tab
2-Download the latest BIOS (Make sure it isn't beta)
3-Use @ BIOS to Flash the new BIOS after making a backup of your current BIOS (you can download @BIOS by clicking the advertisement to the left of the web site mentioned above then selecting @BIOS utility)
4-Reboot

i already downloaded the latest bios and still can't get it running at 1066. did all sorts of tweaks suggested on the g.skill forums but even they couldnt figure it out, decided to just stick with 800 mhz unless anyone else can tell me how to get 1066 to work.
