Windows 7: RAM problem

I have had blue screens after cold boot (4+ hours unpowered) as long as I have had my new system and I think it might be because of "incompatible" RAM sticks on my motherboard sine manual doesn't have my RAM model listed on it. Link to thread about blue screens: http://www.sevenforums.com/crashes-d...d-s-again.html

So what I'm asking:
Is there any other solution to problem than leaving computer to "sleep" mode always after I leave computer?

Why did you choose that particular RAM? It may be OK, I'm just asking.

Have you run Memtest on your RAM, looking for errors?

Here is the link to the RAM compatible with your specific Asus motherboard at the Crucial configurator:

Computer memory upgrades for ASUS P7H55-M PRO Motherboard from Crucial.com

Check the specifications on that RAM and compare it to the specifications on your Corsair RAM.

Check your motherboard manual or the Asus site for the proper RAM specs.

Is your Corsair RAM specifically mentioned on the Asus website as being compatible with your specific motherboard??

RAM/motherboard combinations can be very cranky. Voltage can be critical. Maybe you need 1.5 volt RAM and the Corsair is designed for 1.6 volts---for instance.

I chose that RAM because sticks were 2gb and resonable price (needed 4 sticks) and that type of RAM was compatible with my model of motherboard "with integrated GPU" and mine is without integrated GPU so it was part mine fault..

I ran memtest without cold boot and it found no problems, later I ran it after cold boot and it found alot of problems. After that I tester each individual sticks & slots with no problems (that wasn't after cold boot.)

"Type" of RAM is not enough info.

The integrated GPU versus non-integrated GPU should not matter at all.

Aside from memtest, what else have you done to confirm you have the required RAM, as mentioned in my first post?

Run memtest a half dozen times or so, just let it run through several cycles.

If it generates errors, you should return it, but do you know for a FACT that it is the right RAM for your motherboard?

Model of my RAM is TW3X4G1333C9DHX, I'm not at home so cannot find out more about it and don't have time to try googling at this moment. I haven't checked ASUS site yet, but manual has my model listed on "with integrated gpu" section.

And I'm pretty sure my RAM is clean.

You have an H55 chipset on your motherboard. That means your motherboard will allow you to use the integrated graphics built into your CPU.

The similar P55 chipset would mean that you would have to buy a separate video card for that motherboard. But you can use the integrated graphics because you have an H model chipset/motherboard, rather than a P.

I would go to the Asus site and see if there is a recommended RAM list and look for your Corsair on it.

If it is NOT there, that doesn't mean it is incompatible.

Check the RAM voltage requirements at Asus for that particular motherboard.

Then go to Corsair.com and see if your specific RAM runs at that same voltage.

You said earlier that your RAM had failed at least some memtests. Now you say you think it is "clean", so I'm confused by that.

Primary point: don't go buying more of the incorrect RAM. Confirm if yours is bad by memtest and then confirm if it is even the correct RAM to start with. If not, you have to buy the correct stuff.

But RAM may not be the cause of your blue screens?

Look here:

TW3X4G1333C9DHX P7H55-M site:corsair.com - Google Search

Memtest ONLY finds problems after cold boot so if I run computer and do test after restart, it won't find any single problem from my RAM sticks, but when I leave it powered off for like 4 hours and run memtest after, it shows many problems detected.

My motherboard is the one "without integrated GPU" so I don't have graphic card integrated on my motherdboard.

Maybe if you check my earlier topic you might find something there? I'm not certainly sure it is RAM that causes the problem, but it seems to be closest option.

It sounds like the problem is not with your RAM. Try screen-lock at blue screen and write down error code and google it
