I would run memtest to make sure its your ram. But it looks like it just do an RMA.

Re: Screen flicker after RAM upgrade on desktop

What tRD do you have set, and how much MCH Voltage did you apply?

You need to increase MCH Voltage for sure, maybe 1.24-1.32 for 8GB

Re: Screen flicker after RAM upgrade on desktop

I just tired and put back my old ram sticks and the computer works again as it should. I play some game for a bit and did not notice any flicker, whit the new sticks it start flickering already in the menu of a game.

Ran Memtest86+ V4.10 and it passed, I did not change any thing in the test just ran the standard.

Set MCH Core to 1.2-1.24 for 4GB of ram, also set your memory voltage to spec amount if it is more than 1.9V

Put all "ref" voltages in Auto

And for 8GB of memory you will need tRFC of 72-84 or more at least

All the value I wrote above is what auto sets it as.

I have tried to use 72-86 on tRFC and the MCH core at 1.24v but it did not change anything, I then tired the memory at 666MHz but that did not make any different either.

I have put my old memory pack in. I will properly return the memory on Monday and stick whit my old ones.
Thanks for taking your time and help me.

Re: Screen flicker after RAM upgrade on desktop

K, was just making sure you had those on auto.

And sorry I advised for 4GB, but mentioned 8GB? You may need 1.28-1.32 MCH for 8GB and 82-96 tRFC

So try that before you return them, just in case.

If that does not work, it may be faulty memory or just not compatible not sure?

I have return the sticks now.

K, let us know how your new ones work if you ordered new ones.
