    Hi there,

    I'm making this thread to see if anyone can help confirm whether or not I am getting the most out of my GPU, or if there is something I can do do improve performance.

    I'm on the baseline 2012 15" model: 2.3Ghz i7, 8gb RAM, 256SSD, 650m 1gb VRAM

    I installed Nvidia's drivers (currently running 335.23) soon after installing Windows 7 on my RMBP about a year ago, and I've often found graphical performance a bit lacking while gaming.


    I also managed to find a few screenshots from other RMBP users running the 650m, showing memory clock speeds of 2000Mhz and higher.

    While my 650m's memory clock speed never goes above 1250Mhz (screenshot taken on my laptop).

    I keep the laptop well ventilated, and GPU temperature never exceeds 78C while gaming heavily.


    Any ideas why my memory clock is running so slowly compared to others? Is is because Nvidia's drivers are for basic the basic DDR3 version of the 650m, instead of the RMBP's overclocked version?


    Any insight would be very much appreciated,
    Thanks :)

    Have you tried downloading the beta drivers from NVIDIA? They're reputed to give better performance.

    I thought the baseline 2012 15" model only came with 1/2 gig video ram

    That's the non-retina model they dropped with the early-2013 machines.

    2000 MHz is ONLY in non-Retina MBP because it translates to 4000 MHz(effective).

    Retina Macbook Pro has 1254 MHz which translates to 5016 MHz(effective).

    Dont worry, enjoy your MBP.

    Aaaah thanks, i knew that the total memory clock speed is 4x1250 because of the 4-channel of DDR5, so i suspected the number difference may have been from people posting the speed in terms of dual-channel

    Although the people posting those speeds did say they were using the RMBP with 650m.. maybe I read it wrong

    Thanks for chiming in guys
