2 different versions of xms3

moults · 26 Jun 2011 at 23:04

I had 2 x 2gb of XMS3 memory which was working fine the model number was
CMX4GX3M2A1600C9 1.65v ver 2.3. I decided to purchase an extra 2 x 2gb of the same model number and voltage but when i got them they were ver 6.0.
My system fails the mem86+ test when i have all 4 sticks in place but no problems if i only use 2 sticks.

Could the different versions really make that much difference?

i have treid all 4 sticks individually and in pairs with no problem, it is only when i have all 4 in that memtest fails.
I have the Asus P8Z68 - V Pro motherboard set to run at stock speeds

I was getting several BSOD and quite a few other problems. when i tested all 4 sticks using the latest memtest some times it would pass all tests then fail on the 2nd run. With only 2 sticks (of either version) they passed 5 tests with no errors.

auto settings, i haven't tweaked anything yet although i would like to overclock eventually.

Thanks for your help. Have you got any idea what the mobo would set the timings at when in auto?
Also i'm not sure if the 2 things are connected but when i had 4 sticks of ram i was getting problems with things like scannow which would never complete. As soon as i went to 2 sticks scannow completed with out a problem.

CPUz shows the following. I am unsure about the second screen shot

My screenshot is the same as yours but i am confused about the spd screen which shows 3 jedec columns which show different values.

Thanks for all your help guys, i will do all the suggestions tonight as it will be nice to run with 8gb of ram. At the moment i have 4gb sat on my desk which is about as much use as a chocolate ashtray.
I'll let you know how i get on.

Hi Guys
I have finally had a chance to set the frequency on my memory to 1600Mhz. I haven't changed the command rate but have run 4 hours of memtest with no errors at all.

Hopefully that will be the end of it.
Thanks
