G53sw-xn1 460m memory overlock limit?

Hi guys

I have seen many people with g53s on this forum being able to overclock the memory of their 460m to 1600 MHz and core clock to 850 easily.

My overclock limit is ~800 core and 1500 memory. Even after using the custom vbios raising my voltage to 0.96V which allows my core clock to reach ~840, i still get artifacts and crashes as soon as the memory goes over 1500.

The problem i noticed after comparing the fps in MSI Kombuster was that my fps is basically the same at ~173 with 800 or 840 core clock leading me to think that the memory is the one capping the performance？

Could something else in my g53 be causing this limit in the gpu memory overclock? Maybe the 2+4gb ram combo or lack of power supply due to usb keyboard, mouse and hdmi output? Or am i simply one of the unlucky ones that my card would not overclock further?

Cheers guys

 

Hello, Rest assured, that the memory is not limiting its overlock.
1500MHz is very good, Believe. You will not use even half of all bandwidth available with this clock.

I do not recommend overclocking the memory, by reason Next, you will not earn more doque 1 or 2 FPS. It's not worth it!

And another, Memorias do not have an adequate cooling, especially in this low-Part Video Card. Heat may reduce by more than 50% the useful life of them. and I also increased the amount of errors (artifacts)

Let the memories of a maximum of 1400Mhz.

Also we are with another problem, there is a limitation on the video card that shutting down the system in heavy games, yet we do not know WHAT is causing it, so not worth it This Overlock above 760Mhz on the GPU, because as games BF3, Ira shut down your computer after a few minutes of play.

 

I use memory 1625 " max MSI Aft.Bur" but I agree it doesnt effect much just heating more,,,
But, before I was in stock driver or little later till 275.33 I was not able to rise that clock 1460,,, even 1465 was creating the artifacts and stop driver,,, later on I loaded new driver 275.33 and something changed I have no any idea what happened but now artifacts limit around 1675 so I keep 1625. During this period max stable core was max 825. So later on new voltage mod bios came and now stable clock 855 and memory still on 1625.

Here also another issue, I use G53SW 1366*768 but 3D 120hz screen. In 3D mode, it means require more power than 1920*1080.
As I understood 1920*1080 configuration and 1366*768 3D configuration similar but not same, so what I tried , I connect full HD 42" LCD and changed res to 1920*1080 855/1710/1625 stable maybe I m really lucky but this is the max, whoever say that more than this possible yes but not long, it is only possible if you keep CPU as 2.0 GHZ with Throttle stop then you can rise to 880 core but approx 20 min coming back to stock 675.

So clean driver installation and with 0.962V mod bios, 850 core with 1625 memory I think should be reachable. with this configuration during game play max temp is around 85-88 so fan keeps running of course.

 

Thanks for the reply so just keeping it at 840/1680 and 1500 would be fine ?

 

I use the newest 301.24 driver from nvidia, i have done a clean install since i switched to an ssd. Is it possible that the 275.33 driver would allow better overcloking?

 

Actually I cant say such thing for 275.33 but that driver different I know, it is really quite stable,,,
now I also use 301.24 and for the new game at least should be used 290.53 or over,,, 275.33 will be old for the new games.
but maybe you can try 275.33 first and later on you can update again for the new driver, it was just my experience actually what I faced, 1460 was my max but now totally different, 1625 quite normal,,, and 301.24 also good one I agree,,,

 

Hmm, haven't had the chance to test on games such as BF3 since i dont have it, just played tera which i did get throttling but i think is due to the CPU.

So 1400MHz and 1550MHz wouldnt make much of a difference..? I see you have yours clocked at 1550. So should i leave mine at 1500 or 1400??

 

You should leave yours at whatever is stable. If you care to push it higher, and your temps are fine, then ... leave it lower.

Stable = no artifacts.
Good temp = under 100.

 

The difference between 1500MHz and 1400MHz is around 4.8GB/s for the memory bandwidth, but you probably won't gain much over that.

 

Alright.... first off... your bandwidth knowledge is severely lacking. The GTX 460M does not have enough bandwidth at stock to fully access the 1.5GB frame-buffer it's given. I've managed 1.3GB with my memory @ 1550mhz. Overclocking the memory of the GTX 460M will give you a higher minimum framerate in games and a more smooth gameplay experience.

Second off... overclocking your memory doesn't yield as high results with the higher end GPUs like the 485M/580M and 6970M/6990M because their bandwidth is already at an optimum point. The GPU core is too slow to make use of any higher bandwidth since 1080p is a little intense even for one 2GB 560Ti or 2GB 6870. Which are the desktop models of the GTX 580M and the 6990M respectively.

The memory bandwidth is too low on the 460M as is, I would know since I use the darn thing on a daily basis. I can say with complete conviction that you will yield BETTER results from a higher memory bandwidth with this card than you will with a higher core clock. If you want more proof of this then look up the difference between the 4850 and the 4870. Bandwidth. Proof in the pudding.

The 460M runs VERY cool by comparison to the 5870M, topping out at like... 65-70*C in most DX11 titles vs 80*C. So adequate cooling isn't a problem.

Also, for the OP, what's your ASIC Quality Score? My 460M is @ 74.9%, which is really really low apparently...

 

Thanks for the reply and advice,
What is ASIC quality and how do i check?

Nvm just checked on gpuz, it is 82.3%

p.s: what does OP　stand for?

Cheers

 

mine is 91.1 % but this is really quite variable, as you know this is for the circuit performance, higher of course better and it just seems of your luck,,,

 

Btw, does firmware really make a difference on overclocking, i see many users prefer to use older driver(maybe they're more stable?). Right now im using the newest beta driver available.

 

I don't see any advantages of using the older driver other than the stability, but using old driver also means you are missing out new features like FXAA, adaptive v-sync or performance boost for certain games.

 

I agree for the new issues but I think new stable something should be issued. And for the new games and updates 301.24 can remain or if you have any strong problem you my return to 296.10
