BLUE SCREEN after adding new RAM

[maciex]

Recently after adding new RAM. I've been getting some random BSOD System Service Exception messages. They usually right after startup (from shutdown or hibernation). Its quite sporadic...sometimes it happens a few times in a row, other times its days between them. I'm sure its the RAM connected problem (only thing i've changed since the BSOD started happening)

my original Ram is 2 GB Kingmax 1066 and wit it PC works fine now

but when i add bought 2 GB Kingmax 800 i will have BSOD sometimes immediately sometimes after a day


for now i only use 2 GB Kingmax 1066 the other is not in PC because it crashes

my BIOS settings are now auto

I have attachted needed files

my system is Windows 7 Ultimate x64

its information from WhoCrashed :

oh btw i tried to install drivers for mother board chipset but i have errors during installation

the PC was NEVER overclocked

To determine if the RAM is faulty, please test it with memtest86+. You can let it run overnight. Start it before going to bed, and stop it at your convenience in the morning. Please look at the tutorial on it (link below) for more info on using it.

i did it memtest was running about 2 hours it has scanned over 200 % 0 errors

oh and sometimes it is not even possible to do the memtest BSOD one by one

 

[Petey7]

By 200%, do you mean you let it run for two passes? Most experts in this area agree that 7 passes should be run. 5 passes is the minimum.

Have you tried reseating the RAM?

 

[maciex]

200 % i dont know how many "passess" is that
i will not spend a week for scanning the ram for 55 passes as experts says , because 1st i dont want to and 2nd i cant the Ram is ok it needs to be something different

the strange thing is that the Ram sets in BIOS to 5-5-5-18 which is incorrect i guess , i dont know

ideas, more , please

When you added the second 800mhz module, did you attempt to run it at 1066mhz speeds?

By adding lower speed RAM, you will have to manually adjust the existing 1066mhz modules to match the timings and voltages of the newer and slower 800mhz module.

Without knowing the exact module numbers, it's hard to give specifics.

But for a general example:

If the original 1066mhz module ran at 5-5-5-15 1066mhz @ 2.1 volts and the new 800mhz module is rated for 5-5-5-18 800mhz @ 1.8v - you will have problems.

In this scenario, you need to manually set the timings and voltages to match the slowest modules specs.

ie 5-5-5-18 800mhz @ 1.8v

Also, some of the 1066mhz modules sub-timings could be more 'tighter' than the lower specced 800mhz can handle.

If the BIOS was left to AUTO, then the timings for the faster module will be set, and not adjusted for the slower module.

Plus if the voltage options were left on AUTO, you could have been overvolting the 800mhz module. As a general rule, DDR2 can take up to 2.2v before causing damage/issues. But, there are always exceptions to the rule.

Some RAM just does not like being overvolted.

With the 1066mhz module in place, I'd manually set the timings/frequency/ voltages to match the 800mhz modules specs.

Then I'd remove the 1066mhz module and replace it with the new module with the looser timings to see if the machine POSTS, functions correctly. if it does - add the original module.

but how to do it ?

timings frequency voltage ?

what are the right ones ?

 

[smarteyeball]

The modules themselves should have a sticker/label on them that state what the timings and voltages should be.

Alternatively, if you could you provide a link to the new module I can look for myself.

But these settings should be loose enough:

In the BIOS under A.I tweaker:

DRAM Frequency [800mhz]
DRAM Timing Control , 1st information 5-5-5-18

Memory Voltage [1.80]

I found the answer!!!! Wooohoooo!

YES! I found out how to fix it. I had the exact problem and it took me ages finding out how to fix it! I wanted to return my ram but luckily I got the answer of how to fix it.

Best Solution 1: When you add the ram it comes up with this thing saying Setup or Continue without setup something like that. What you do is you Go to setup which leads you to your Computers BIOS page. If you look I forgot where it was but somewhere on the screen it says voltage thingy. My one was at 1.8 and You need to make it to 2.0.

Solution 2: On the BIOS page look for writing which says Dual Channel. Some computers do not have this option and some do. Dula Channel might be off. If this is the case then turn Dual Channel on.

Solution 3: Some computers like mine the ram is in slot 2 and 3. Make sure it is in slot 1 and 3. I have heard in some places that you can also put the ram in slot 1 and 2 but I recommend that you put it in slot 1 and 3.

Hope this helped!
