NEW XPS 15 (L521X) CPU throttles to 1.2ghz when gaming

  • When gaming on my new XPS 15  (L521X) | I7 3612QM | GT 640M -  I noted that the frame rate was dropping significantly after about 1 minute. (note: running on A/C power - not battery)

    After loading up EVGA Precision to monitor GPU FPS and CPU Z to monitor CPU - I noted that initially when the game starts up the CPU boosts to 2.9 GHZ, but after 1 minute it throttles to 1.2ghz and stays there.

    Troubleshooting steps taken:

    Updated NVIDIA drivers to - no change

    Downloaded A04 BIOS and installed (was already at A04) - no change

    Changed power profile to "High Performance" - no change

    I was expecting this laptop to outperform my E6530 but that is not the case with the CPU throttling - if a solution is not forthcoming in the next few days the laptop will be returned

    Note: When running the same game on my Dell Lattitude  E6530 | I5 | NVS 5200M -  the CPU boosts to 3.3ghz and stays at that speed indefinitely.

    Here's a thread I found on notebook review forum where another user posted the same issues:

    Thanks for posting this in DCF.  I know that you have spoken with Dell-Bill B and I have your information.

  • Thanks Terry!

    I sent you an e-mail with my order info per my discussion with Dell-Bill B

    I'll be dropping off the unit with Bill on 7/10 (good to be in Austin)  :)

  • I am also experiencing this issue with that same model. I'll see if I can contact a dell rep later today.

  • Well I confirmed with the rep that going from 2.9 GHz to 1.2 GHz while using processor-intensive applications is not normal. Waiting on further information from them...

  • Just noticed a reply here:
