Hi. Actually I always let the voltage standard and all the parameters too. One of my last changes was trying to set the voltage manually and the values but I was not sure about where to put these last ones in the bios (lots of values) even having them printed in the sticks. But at the end it was not successful . The system became very unstable into Dual but capable to boot. So, I changed to Single and it is stable.

PS: Rarely I can boot with one of the G.Skill. Just with the Corsairs in my Intel.

PS2: I bought these G.Skill because about Asus they should run without problems with this motherboard because they are certificated but who understands.

What do you think? I will picture the bios values and the values printed in the sticks.

Here are the Pictures, if you do not mind, Guide me to set the values into bios. I am kind of newbie about it.

So, what I can conclude that the problem is either the CPU or Mobo ( M4A87D). What do you think?

To exclude a CPU issue, you should run the Intel CPU Diagnistic Tool. You can grab it from >here<.

Hello, What's up.

About these problems with this mobo and after noticing that the 5830 was dead I replaced her for an XFX 6870. All is OK concerning about the video but after testing and testing the dual channel refuses to work properly. When it works a lot of Blue Screens appear randomly. I tested (replaced the G.Skill Ripjaws ) to Corsairs One ( what I use in dual in my Intel PC) and they are also unstable with the AMD PC.

Testing the G.Skyll in my Intel they work well .

So, what I can conclude that the problem is either the CPU or Mobo ( M4A87D). What do you think?

Hi there.

you run DIMMs with very low latencys programmed (CL7!), while JEDEC specs are CL11 for DDR3-1600. I bet your DIMMs voltage isn't "standard" either, right? Probably, the mem controller doesn't provide enough power or sets the values wrong, so if you are able to enter BIOS (with one DIMM?), set the values, which are printed on your sticks MANUALLY. As COMMAND RATE choose "2T" or just "2", that is the "normal" setting. Most boards won't boot with this "uber-clocked" memory, while values are set to AUTO. I had a rare testkit from a big company once, with DDR2-800 DIMMs with 3-4-3-8-2T @ 2,4V. It took me 5 (five!) boards until I got one which booted with those sticks.

Sincerely
