so did you try putting old ram and new ones in every second slot?
Also try running with only 2 sticks where one is new and one is old and then report the results.
Only 1 stick Crucial 1 stick Micron in slots 1&2=2933. Swapped with other stick of Micron and other stick of Crucial=2933
only 2 sticks Micron in slots 1&2=2933
only 2 sticks Crucial in slots 1&2=2933
Anytime other 2 sticks (whichever sticks they may be) are added to 3&4=2400
I had an open service request on this issue with Dell but they closed it with no explanation. I tried to open another service request and Dell won't even talk to me about it. Says it's not their problem. Guess I have no option but to live with it because I've already spent a mint over and above the original cost.
The history of this system is bleak. About a month after I got it , it overheated when I tried to use Photoshop. I found it to be the inadequate pancake cooler so I contacted Dell. Their answer-disable hyperthreading to cool it down...and they really considered that a solution. Having to take it in my own hands, I bought a complete Noctua setup which fixed that but the Dell mobo began throwing fan errors so I had to then buy a premium cooler and larger case fan from Dell. It fixed the cooling but is no where near as good as the Noctua setup was. Noctua dropped temps 15 more degrees than the Dell setup but the mobo just won't accept the Noctua.
2 months (and 3 bios updates later)the PC started throwing kernel power errors and would not sleep so Dell's solution was to use hibernate rather than look into the problem of sleep. 3 days later they issued another new bios and no more kernel power errors.
And now, a month later, the ram issue. All this has happened over the last 6 months. Hundreds of hours spent troubleshooting and dealing with Dell's foreign support, being passed from one dumbass to another in a vicious circle, the single worse experience I have ever had dealing with anyone.
Thanks for everyone's input.
