I've set dram timing to both, bumped the nb to 1.22 and ran memtest, it all passed fine but i'm still getting a blue screen intermittently on or just after start up

I am also now getting the computer freezing when left for a while and i get a black screen


any idea as to whats now causing this? Is it all memory related?

It is possibly caused by RAM but, there are other possibilities, could be the motherboard, memory controller that is integrated in your CPU, power supply.

Lets check the RAM out first.

Please confirm that you tested the RAM with:
DRAM 1.55v
NB 1.22v
Command Rate at 2T

If these settings were what you used to test last time, then bump the DRAM to 1.6v, then the settings will be:
DRAM 1.60v
NB 1.22v
Command Rate at 2T

Run memtest86+ at cold boot.

Let us know the results.


If this voltage bump doesn't help, can you get another two RAM cards to test your system?

That would confirm if it is the RAM causing the errors/BSoD.

The majority of the time cold boot errors/BSoD's are caused by faulty RAM, sometimes adjusting the settings will help but, usually end up returning the RAM.

Let us know how the test goes.

Thanks for the reply, as I said earlier I can't find the option to change command rate to 2T

The only one I've got is dram timing mode and I've got the options of

Auto, DCT0 DCT1 or BOTH, no 2T

So at the moment I've got dram 1.55 and nb 1.22 and dram timing mode to both

If I were to get some more ram can I just fit them with the same settings that I have altered or put them
Back to auto?

Bump the DRAM to 1.60v and run memtest86+ at cold boot.

If you get new RAM reset them back to 'Auto'.

ok it's been over a week now and so far so goood, no BSOD, so fingers crossed

One question, if i was to put more ram in this pc and it was a different brand, would that work ok and will the voltage settings be ok with the new ram?

Glad to hear it's been running stable for you.
Thanks for letting us know the status.


It's best to try to get the exact same RAM that you have now or buy all new RAM and keep the old one for spare or sell it.

Be sure you get the same timings, voltages and brand. Same part number. Even then, if they changed any spec or upgraded any components, it might not run together.

Mixing RAM from different manufactureres usually doesn't work, at best you will be changing settings and running tests for weeks trying to get it to work.
