M15x and GTX 560M

i think you can push even further

 

see attached


can anybody explain it ?

 

As your memory clock increases, your bandwidth increases. Similarly, as your core clock (GPU Clock) is increased, your Pixel Fillrate and Texture Fillrate increase.

 

So is this behaviour is perfectly normal ?
Nvidia dont talk about it thats why I ask, is it one of the hidden powers ?

 

Perfectly normal. Think of a conveyer belt. If the standard speed of the belt is 4 feet/sec, but the speed is increased to 5 feet/sec, then, all other things being equal, the belt will be able to transport 25% more material in the same period of time. Same concept. You're increasing the speed of the belt.

 

ok Thanks, I wonder what its max is

 

As a practical matter, the max is the level just below the level at which the card crashes. You can't calculate it in advance because it is subject to various situational variables, including load, heat and available power, that are not known with adequate precision, plus individual cards vary in their ability to accept o/c'ing and remain stable.

 

I just cranked mine up to 900/750/1800 as well. I managed a P2527 in 3dmark11 with an i7-820QM CPU. I did hit 75C. My physics score was a bit higher I'm assuming due to the CPU difference. If this is with the card being essentially brand new, I wonder if we can expect future gains with new driver releases.

Also, my 560m has the same hardware ID so the driver I downloaded must have already been modified for it.

 

Yes thats correct, i checked your nvdm.inf file
and it has indeed the correct hardware ID loaded

 

Can you motivate this and you will be blessed

 

i'm curious to see if it can beat a 5850 !

 

what clocksettings pls specify

 

Got a long way to go to catch the 5850M's. Making good progress though.

 

just push with 10mhz increments until your reach the cards maximum stable clocks. As i remember correctly the 5850 highest score was 10500 vantage gpu

Good luck

 

Here's a 5850M target for Vantage and Vantage GPU. Crank up those 560M's and bear down!

 

I am ready to do some more OC.

If I get ADVICE I will run it tonight

 

was this without aux cooling?

 

Well currently your vantage GPU score is 9.9k try raising the memory to 1600 and the core to 925. As you may know, the 5850 can achieve over 10k GPU score. We need to break that on a lower high end nvidia card.

 

Based on the clocks, that was probably sitting next to the a/c. It's been a while, so I don't remember specifically. Feel free to use one, but dutchess63 has reported excellent temps and probably wouldn't benefit much. That may change when he installs the 940xm.

I'm pulling for him. The Dell 5850M/5870M has been at the top of its class for a long time. It's past time for some new card to come along and dethrone it. I retired mine some time ago, but it was and remains a great laptop video card.

 

Well the max setting for memory is 1500.

 

GTX560M

GPU clock max setting = 1550
Memory clock max setting = 1500
Shader clock max setting = 3100

 

Ok sure try 925/1500 then

 

try using evga precision for higher clocks

 

Here are some more results from the Netherlands:

The driver(280.26) crashes just above or around 915/1500/1830.
Anything above that got worse. (I pushed to 950/1500/1900 increments of 10)

Temps stayed fairly low CPU & GPU max 73 celsius.
Therefore I do think its a driver problem.
Not the card is on its max but the driver is apparently is ..

The driver just resets back to default clocks
when it happens and 3dmark hangs.

Scores:
P2575 3dmark 11
P10336 3dmark vantage

Pls comment or suggest and I will look into it, cheers

 

Wool! 10k! Nice. Maybe use another program to try higher memory speeds. I've seen them go as high as 1800. But see if you can get 910/1600

 

Just mention the name of the program for 910/1600 and I see to it that it gets done

 

EVGA precision may work, nvidia inspector, amongst others. I'd try Precision.

 

see attached and let me have your ideas

 

Click unlock max on inspector. If it allows higher overhead, set your shader clock to 1820 and your memory to 1600.

 

thanks, that does the trick ! I was looking for

 

MORE POWER.

​

 

yes sir! i can boogie !!! boogie woogie all night long (and morning !!!
nice pic

P10411 vantage

see attached / temps kept 73 max

3d11 score was actually lower, still cant believe it but okay,
so I leave it out here now

what is the next (logical) step up ? I need nrs to set...
pls advise

 

Well seeing as the core will no longer rise. Perhaps push the memory 50 MHz at a time? Perhaps you should call it a day? You have a great GPU as far as we all can see Hopefully your XM CPU will help.

 

Good effort and a very nice 560M, quite an overclocker. Great temps given that the card was pushed to the limits. Be interesting to see how it develops with refined drivers and more powerful CPU's. A much improved and very worthy successor to the 460M. +Rep.

 

actually I tried 950/1700/1900 right after P10411 score but that crashed on 1st run. so if I get you right : 910/1650 and after that 910/1700 and so on correct?

 

Yep no point raising the core anymore.

 

Max Stable is 910/850(1700)/1820 - temp 76 celsius

The card is really really slow qua temps
and imediate switch back to normal 40-50's. Its amazing

I will continue with i7-940XM - knock on wood 5850
flying dutchman are crazy, and I am at ur tailend already.. jihaaa..

hope by saturday to have it installed

 

Wow nice! Just about on par with the 5850 nice one.

 

Now revisit 3dMark11 while you have it all stoked up.

 

ofcourse for the books and I never sleep

P2578 - 3dmark11

P10522 (>10K GPU ) - Vantage

 

Wonder why you're not seeing a larger improvement in 3dMark11? It's more a test of GPU performance than Vantage.

You're right on me in Vantage with that P10,522. Using an 820QM (functional equivalent to 740QM), my old 5850M topped out at P10,533. So with the more powerful 940XM, you should blow right on by the 5850M's P12,240. But the 820QM/5850M set scored P3055 in 3dMark11 versus the 560M's P2,578, so there's still a lot of ground to make up to take out the target of P3287. Still, very nice performance increase from Nvidia.

 

See the online highscores 3d11 and 560M :

Search

Looks like Toshiba already has a stable driver out @ corespeed 970

Since I can make any driver work with that device_ID trick
I might just try that too

 

Good reference. 3dMark11 looks unlikely.

 

I investigated a bit more > well the toshiba driver from the online highscores is actually a verde 280.26 driver with different set of instructions in the .inf file. memory instructions are raised from 80 to 128. which makes it interesting..

So I tried to load it and got it working ok - but in the end it didnt add to system stabilty for M15x overall and 3dmark11 crashed - so I leave playing with it for now. .

But still wonder how they crank the 560M up to GET stable 970 core speed.
The 560M allows for it for sure!

Might because the toshiba is a sandybridge system with
integrated graphics in the processor?

 

I long for sat/sunday - my I dont have to runday
finally

200% time for M15x

More good news to come..
My little baby 940xm has arrived

cheers,

 

I am now on 940XM : Here are some results and questions :

The 940 is an ES Q4AP (QS) Quality Sample.
Main screen in TS you can choose to set multiplier between 9-16 and turbo,
but the value 17 (that I have seen in some pictures on the forum) seems missing.. dont know why?

So
After playing a bit around I set in TS : TRL & TPL to be:
1) 24-24-24-24 @ 83W/73A

Benchmarks:
P17524 3dmark06

Move on with 3dmarkvantage:
I experienced some strange throttling and I can not figure why. Temps were higher on this 940XM compared to 740QM but below 90 celsius. Temps on the 560M were as low as always around 73 celsius. May be someone knows and can advise me a bit ? :

Benchmarks sofar:
P10968 3dmarkvantage CPU Stock clocks (& GPU at 910/1700/1820

After this I raised to 24-24-24-24 above for the CPU :
But now I experienced throttling on the GPU(thats what I think at least), cause the CPU score rised but the GPU score was getting lower.
I could SEE the FPS going down each 10 secs or so to almost ZERO and then quickly go up again. Really very frustrating to see this

After this I raised CPU multipliers further to 28-28-27-27 @ 93W / 75A
Stable CPU ok ... but SAME THROTTLING happened.
CPU score went up allright ... but the GPU went SAME down.

So who can shine a little light on this pls. Is this normal ? I like to learn, how to get this baby flying best
Do you OC only 1 of the 2 : CPU / GPU at same time ?


Many Thanks for ur help

 

The GPU throttling is probably a Nvidia disease, same happens with the 460m as far as I know, widezu knows probably a bit more about this since he has done quite some testing with the 460m & 920xm combo.
It seems that the 460m (and apparently also the 560m) can't be overclocked without throttling when pushing an extreme CPU at the same time.

That your CPU temp is higher than with the 740QM is absolutely normal, the 940xm has a stock TDP of 55W vs the 45W of the 740QM. Now in the M15x the TDP of extreme processors get automatically set to 62W, which allow the CPU to deliver Turbo Boost for a longer time. You raised the TDP even further with TS, which results in even more heat as long as there's load on the CPU.
24x across all cores at 83W is reasonable, and should be possible for everyday use without heat issues, 28/28/27/27 is awesome and pretty much the maximum unless you start tweaking the voltage, but to run it at such high speeds you'll need more than 93W, else you get throttling (unless you live in a very frosty environment).
For extreme OC like 27x on all cores you'll need additional cooling methods when benching, else you'll have thermal shutdowns.

 

What were your scores when you took it up to 28-28-27-27? Agree with svl7's comments, but would add that it appears that you may be encountering power throttling, meaning essentially that the collective power demands of the 940xm and the 560M at those o/c levels are more than the M15x's PSU can deliver. Because the 560M's are new, we have no experience with the power needed to support the card when heavily overclocked, but the 75W TDP suggests a big appetite. Very reminiscent of the 6970M (also a 75W card) experience in the M15x. You'll have to experiment to find the most efficient use of the available power with no guideposts at this point. Early adopters always have the most fun.

 

Ive been doing alot of overclocking with a 940xm and 460m and Its a give and take ive noticed. you have way more to go with the cpu doe a vantage score. Ive broke 21K but then i get crap for GPU. I recently did an AC cooled run and managed an 18K 06 score but my vantage score was only lik 8K but with a 21k score. we can not handle both the Extream cards and maxing out the GPU at the same time. Just wont happen. If you have a channce to put your laptop on an AC unit and freeze the crap out of it like I did I ran 28-28-27-27 at only 27c.

 

When I had the 460m GTX with the XM CPU, I could never bench or play games with both OC'd. I have to choose one or the other.
