no dice. think i really did get a lemon. enabled overclock support in bios. went down to memory frequency, changed it from auto to 1867 left voltage as is and rebooted. got bsod again

@deadbydawn also had this issue with his Corsair Vengeance ram. Another user here at T|I pointed out that he got his system to boot with the ram by first setting 1866 MHz in the bios with his 1333 MHz ram, removing it and then putting the Corsair 1866 MHz ram in. Otherwise the system will not boot. Try that and see if it resolves your problem.

would i need to switch to any xmp profiles?

I got a set of these for my notebook (alienware m14x r2)

Newegg.com - CORSAIR Vengeance 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1866 Laptop Memory Model CMSX8GX3M2A1866C10

and my laptop either BSOD's or refuses to boot bringing me to the system repair screen.

edit: just read this

" IF THERE'S A DEFECTIVE MODULE, OR IF THE RAM YOU PURCHASED turns out to be INCOMPATIBLE, Windows simply will not boot, and your PC will act "dead". In that case, remove it, and return it to the manufacturer/distributor for replacement or refund...and stick the old RAM back in until the replacements arrive."

other users have said this ram is compatible with the R2.

In this case, did i get a lemon?

1. The m14x is not capped at 60fps. I play bf3 above 60 all the time as well as other games. 2. the cpu and gpu have a "shared" cooling system. If you lower the cpu speed by disabling cpu turbo it will not "heat soak" the GPU and help keep it cooler. It really depends on whether or not your game or program requires the higher cpu clockspeed. 3. You should ALWAYS take steps to make sure your machine is running at its best. Setting windows to run for "maximum performance", cleaning registry, keeping hard drives defragged, removing unnecessary services and or drivers, etc. Good luck, StevenX

I mean my monitor's refresh rate is 60 hz seeing as i don't play with an external monitor & nvidia CP vsync being forced on.

Yeah i keep my laptop optimized and have already done everything that you've listed. Thanks

Has anyone else here installed the 310.61 beta drivers and has had problems forcing their m14x r2 to sleep while closing the lid?

i'd like for someone else to confirm/deny before i uninstall to check

Im really not sure on this one.. The 650 is a strange beast in that, if the utilization threshold is not met, it will not fully turbo correctly. If the temps get to high, it will down clock. Have you tried completely disabling the CPU turbo (using the same gpu clocks) and see if the same issue happens? Thanks!

yep. its not cpu. also i can easily force 99% usage (if that's the usage you're talking about?) by turning vsync off, but seeing as the m14x r2's frame rates are capped at 60 i don't see the point of turning it off

should i try turning off windows aero and force the cpu to process more of the graphics n see if it will affect anything?

would forcing dynamic throttle off using nvidiaInspector help my case?

i'm also experiencing small downclocks while i'm gaming. it causes some weird input lag as well similar to 60 fps spiking down to 30 fps (except im still flatlining at 60). ive tried different clocks (135 & 250, 200 & 400) and still experience the issue. i also tried turning off my turbo boost and it still happened (blops2).

the downclock near the end is when i alt tabbed, which can be deducted from my gpu usage. the problematic downclock is during actual gaming as you can see under Max: 1150 MHz

I also have a GT 650M in my laptop which I do some gaming on occasionally when I'm on the road. I also see this behavior with some games in certain circumstances.

What you're seeing is the boost clock being dynamically throttled down due to power or thermal constraints. Unlike CPU overclocking, overclocking on Nvidia Kepler GPUs basically just raises the clock speed ceiling for boost, instead of setting a hard clock target at load like CPU overclocking. Your temps are well out of the range of thermal throttling, so it's very likely the GPU boost clock ceiling is not being reached because the GPU is exceeding its rated TDP at such high clocks under certain loads, which forces the boost clock to lower to remain within spec. I'm not sure that there's a way to modify the TDP target of mobile Kepler GPUs, but if so, that's the solution to your issue.

if this is the case what can i do?

The 310.54 beta driver is broken crap. The only reason I have still installed it is Black Ops II. My card idles at 405MHz instead of 135MHz, and clocks do not match with the overclocked values. I think you experience similar troubles, pretty sure the driver is to blame.

that's the exact reason i have them installed lol. i read over at a couple different forums where some folk were saying the 310.54 wasn't warming up to overclocks. Hopefully the stable version is released soon

i'm on an r2 with the 650m and i'm only experience peaks of 63C and it never stays there that long. I'm running a pretty high clock too (+315 & +800)

here are my tests

Using MSIAfterburner

I just now flashed using InsydeFlash. Was a complete success and had absolutely no problems. The only thing i see out of the ordinary is the BIOS file being [invalid] in nvidiaInspector, but i'm assuming that's ok. Will report back with some results

Using MSIAfterburner

one question, i dun understand the way to create a bat file in nvidia inspector folder.

my nvidia inspector is directly can be found on my desktop, i tried to search for its folder but couldnt get it, in which directory should i look for?

the folder that you downloaded that came with nvidiainspector. it's a binary (portable app) so just drag your bat file into the folder. It should only have 2-3 files in the original download.

Because the card is soldered to the mobo, the vbios is part of the bios.

does this mean the only method available is to flash with windows?

Hey guys,

I have figured out how to avoid the throttling issue on GT650m. Below is my solution:

Tool:

Nvidia Inspector

How:

1) Launch Nvidia Inspector. Navigate to Over Clock panel on the right side. Select "Performance Level 1 (P5).

2) Unlock max. Adjust gpu clock and memory clock for your own, I prefer 700-750 Mhz for GPU and 2000Mhz for Mem.

3) Create a shortcut for this settings, it is saved at Desktop by default so you just run this file next time and no need to launch Nvidia Inpector

4) Create a Bat file (e.g: Gaming.bat) and place it in Nvidia Inspector folder where nvidiaInspector.exe locate in. Paste the command below into the Bat file

nvidiaInspector.exe -forcepstate:0,5

Run:

Each time you want to play game, just run the Clock shortcut first then run the Bat file. It will force the GT650m always performs at your configured clock

Result:

I tested my own and it works perfectly although the temp increased quite high (70-80). 81 is max of my laptop (I am from Vietnam, a hot country ) but I think this temp is acceptable.

The test is performed with default Bios A09

TRY IT and let me know your result.I guarantee it works.

// Sorry for my English

is this the only alternative to stop temp throttling?

I haven't noticed improvements, haven't tried benchmarks yet, but it pushes my WEi 7.3 (650m). This driver also seems necessary to run black ops 2. So far it has been stable, and i haven't had any crashes.

I love the quality of my m14x r2 but i wish it had a more powerful gpu. i'm currently clocking it to see how high it can go. So far people have compared overclocked rates to the power of a 660m

Would this be necessary if i wanted to OC with the nvidia Geforce GT 650m using the unlocked VBios in this guide here? http://forum.techinferno.com/alienware-m14x/1841-%5Bm14x-r2%5D-vbios-mods-unlocked-overclocking-limits-voltage-tweaks-modified-clocks.html

which method is better for overclocking? flashing vbios or using nvidia inspector (nVIDIA mobile Kepler 6xx MASTER overclocking guide. Workaround for max clocks/OC stability.)

Also, is it a good idea to disable CPU Turbo Boost 2.0 in BIOS when overclocking GPU this high?

As for instructions on flashing my BIOS, i would just run the insyde application from my desktop, reboot -> F2 select Default settings and Exit saving changes and that should be it? No enabling overclocking in BIOS or anything like that? After flashing can i delete the A03 VBios File?
