Windows 7: RAM displaying different CAS in each slot?

Very interesting. I like Dwarft's method. I have never had that happened with matched ram.

Thanks for the feedback guys.

Dwarf, I reset the BIOS / CMOS via your steps so everything went back to default settings. I tried Memtest with the individual sticks and I get the same results as mentioned before. Then I tried ionbasa's suggestions with both XMP profile and manually changing the CAS latencies but they still appear as 6-6-6-20 on the test. Perhaps this is normal for those two slots to read my memory that way? When I Dual Channel, Memtest and the BIOS will read it as 9-9-9-24.

And yes, my BIOS firmware is up to date.

That is certainly not normal. What timings are displayed by the SPD tab of CPU-Z? Are the timings you are reporting mentioned on this tab?

Dwarf, here is what CPU-Z is reporting for both slots (Dual Channelling right now).

Unless you wanted me to see what CPU-Z reports if I'm running with 1 module in Slot 1 or Slot 3?

Yes please, since those are the slots that are giving you those timing figures. I see no mention of those figures on your SPD snips though, which leads me to believe that your board could be faulty.

Alright here's the results and a pic I got from doing Memtest single channel earlier.

What timings are shown on the Memory tab of CPU-Z? It would be helpful to use just a single stick of RAM (the same one) and show what you get on this tab for each slot. The SPD tab shows you the available timings as stored in the module's SPD chip, whereas the Memory tab shows you the actual timings currently in use.

The CPU-Z reports in post #16 are from using single sticks. I used the same stick in Slot 1, took the screenshot, and then turned off computer to insert it in Slot 3 and took that screenshot. Running on 4GB (1 stick) right now in Slot 3 as we speak.

EDIT: Sorry, just re-read your post... let me grab the Memory tab.

Okay, here is the Memory tabs for the same stick in Slot 1 (top) and Slot 3 (bottom).
