To any who want to try and beat my score... and I hope you do! Don't brick your new computer, please. I take no responsibility. Been working with this stuff all my adult life... if you aren't super-comfortable with this, re-think.
Theoretically, your Y500 should be just as capable of reaching that score as mine. My P3239 is the highest of three consecutive runs. The score will vary by a few points each time. Use a cooler or place the laptop on a fan. Watch your temps on a second monitor, if you can. I haven't noticed any impact on the score when running dual external monitors.
You must stop the CPU from throttling completely and set it to run at 3.2ghz. To do this, set C-States, BDPROCHOT and Turbo Short PWR Duration to "disabled" in the svl7 modded bios. Use ThrottleStop to lock your multiplier to 32x, 33x or "Turbo". 32x should put you at 3198.8ghz. 33x and Turbo do the same thing. It tops out at 3.2 ghz. I'm not interested in unlocking that limit at the moment, but I did see a 3DMark score from what looked like a Y500 that reported CPU at 3.3ghz. It was probably throttling. The physics and mixed portions of the test are CPU-intensive, so steady CPU is better than bursting in this case. Also, any bump in CPU speed will yield a higher score. As a side note, disabling hyper-threading yielded much lower scores across the board. The decrease in heat generation was not worth the performance hit for me.
I had best results on the 310.70 Nvidia driver. I would NEVER recommend what I'm about to say if I hadn't experienced it myself, but... let windows upgrade the driver for you. (gasp) I was on the Lenovo 306.00 driver and had tried 310, 314, etc Nvidia installers, with varied results. In a moment of insanity I went into devmgr and clicked on the GT 650m, then upgrade driver, then search automatically. Windows found the 310.7 driver and replaced the 306.00 driver without much fanfare. After a restart I was surprised to find that my Windows driver update was working beautifully... that's when I achieved the posted score. My previous experience with Windows updating video drivers has been overwhelmingly poor... so poor that I disable those updates on my client's computers. This time it worked nicely... dunno. I'll take it though.
I used the latest Nvidia Inspector (1.9.7.0) to set clocks at 1150core and 2700 mem. Anything higher and there is simply not enough voltage to get it done. Hoping to be able to bump up the juice a bit eventually, but to be honest these gains are impressive as they stand. Crysis 3 runs on maxed out settings without issue. Planetside 2 with the "ultra" settings mod runs excellently and never drops below 25FPS. Pretty good for Planetside. Those battles get busy!
