Safe to overclock gt 650m to gtx 660m speeds?

I read a forum which said that the gt 650m with gddr5 is the same card as a gtx 660m with gddr5 just with different clock speeds. Would overclocking the gt 650m to gtx 660m clock speeds in the m14x generate too much heat or cause it to be unstable? thanks

 

What people have been saying is pretty much right. A majority of 650M's within the M14X have insane overclockability.

You can overclock the core by 135 and memory by 1000!! with dell official bios, the only thing with the 650m is they have throttling issues once they pass a threshhold of around 67 degrees celcius, which means they will drop in performance, also - the warmer it gets, the M14x fans will alot grow louder, which is a big turn off for alot of people and one of the only things I dislike about the M14X - if you don't like it, you can always revert back to standard clocks, or a overclock threshold that you find satisfying with no issues.

To get better temperatures i usually prop my alienware up onto a book or something similar - allowing the fans room to breathe.

To achieve both temperature monitoring and overclocking - I suggest downloading MSI afterburner. All overclocking is safe, if you read into it and don't change anything without knowing what it does.

Before I do anything of the sort, I look into it - I have never had an issue.

I also forgot to mention : Some 650M's Glitch at certain memory clocks beyond the 800-900 threshhold. So - if you see screen tearing, or something similar, it may be a good idea to reduce the memory clock.

 

What would a good solid OC be that wouldn't hit the heat threshold?

 

This will vary from card to card, as well as the OC limit.

Download Hwinfo64 and keep an eye on your temps while OCing little by little, it's the safest way to go. Remember laptops have a harder time dissipating heat, you don't want to break the card.

 

If you hop on over to tech inferno they have some custom Vbios posted over there that you can download and flash to your card. I have my GT 650m running at 1100 Core 1200 Memory. Stable and below 65C while propped up.

 

i was looking into this.

prob is my mobo shipped with A09... i can max the core slider on MSI no prob & with out much difference in temps, so im sure i can go higher but right now all the newer games i do run about 45-50fps or better. so not much of a issue yet. i plan to have this as my main rig for the next 2 yrs or so. so i might just wait till it starts showing its age before i go thru with the modded Bios.

are you noticing much of a difference with the mem clocks that high? is 1200mhz mem clock real speed? so 2400mhz effective clock?

 

Man, I've been throwing my clocks up higher and higher expecting this thing to eventually BSOD but it never happens, lol. I dont have the time to stresstest the clocks but I've done around a 15-20% OC very safely.

 

BSOD isn't the only sign of overclocking too high... crashing to desktop and just general game freezing has happened to me, and red screens followed by a horrible noise.

 

Those are the main symptoms, please take into consideration that overclocking might damage the PC and it would not be covered under the warranty unless it was done at the factory by us.

 

Its 2400 Mhz effective memory. I'd flash the bios while it has warranty so if its bricked its covered.


The AW Reps will say it isn't covered but if its bricked theres no way to know.

 

MSI can overclock ridiculously high if you look around for a workaround to get the sliders to go higher, it involves overclocking higher then what is deemed "safe" though.

If you take baby steps you should be right.
