RAM changing timings

Earlier today I moved the RAM chip from channel B to channel A. I had put it in the wrong slot when I built the rig, and figured that it makes more sense to have it in the A-1 slot(as I have a single 8GB chip). I booted up and somehow expected an increase in performance, but alas, the timings had changed from 4-5-4-(something) to 11-11-11-30. Does anyone have an idea why this happens? And will I be better off continuing to have the RAM in channel B?

RAM: Kingston DDR3-1600/PC3-12800 8GB
Mobo: Gigabyte 970A-UD3P

More about ram changing timings
  1. The reason I am asking is that I am failing Prime95 blend, and I am sure it's not my CPU. I have read that loosening the timings on the RAM might solve the problem, but I don't know what the next "step" is after 11-11-11-30. Does anyone know about some "good" timings I can use?(Hopefully with minimal performance loss)
  2. What's the actual model # of the DRAM (can find it in CPU-Z under the SPD tab as Part Number)
  3. The part number is: 99U5403-159.A01LF

    Might try raising the DRAM voltage + 0.05 and CPU/NB up to 1.2

    Ok, I'll try adding some voltage to the DRAM if you think that'll help stability, even though I haven't OC'd the RAM itself (only OC'd CPU and NB)

    In the gigabyte BIOS there isn't anything called CPU/NB, but I am assuming "NB core" is the equivalent? I that case, it is 1.2V stock. Should I try bumping it to 1.25-1.3?
  6. 1.25

    Bumped NB/CPU to 1.25 and DRAM to 1.55, still error in P95. I am going to try setting NB/CPU to 1.3, and post the results
  8. Still error with dram 1.55 and cpu/nb 1.3, even upped the voltage on cpu a bit just to be sure. Is there anything else that affects RAM stability with OC'd CPU?
  9. Could try running Memtest, might have a bad stick...also check that you have the latest BIOS........
  10. CPU/NB at 1.3 and a slightly different frequency (FSB OC) did the trick. Stable for 13 hours prime blend. Thanks for your help!
  11. No worries, glad to ;)
