3d games over w510

[aldimeola81]

the problem is that those with onboard video graphics have a really slow, even the menu 'windows and animations go in slow motion

I must say I never experienced this issue. Not with drivers properly installed at least.

yeah, maybe I exaggerated a little, but the speed 'menu on a PC with 3d card and one with an integrated board is very different, both on windows and on linux


I tested how the scheme works on the W510 fan operating under stress, it is very different from that of T60: the fan is able to maintain a constant temperature that oscillates about 60C

lenovo has obviously been able to learn from their mistakes

[jcvjcvjcvjcv]

You mean they improved the cooling... or increased the throttling...

@adda:

Why do not you care about the W530-540? you think are scarce products?

according to a friend of mine who deals with reballing, the temperature is not the real problem, the real problem is the lack of lead into balls., lead makes the ball more 'elastic welds more' accurate, easy mounting tab without creating tensions within the installation is carried out at temperatures more 'low and do not hassle components etc..

if this were true models before 2005 so they should not suffer from these defects .. in fact my toshiba m30 2004 with NVIDIA GeForce FX GO 5200 has toured for years 24H a day, played with overclocking, the fan makes a noise hell, the keyboard works very badly but still works in the hands of a friend who keeps him always on.

I did a reflow on the t60 , bringing the temperature of the GPU at 260C for 10 seconds, now running again , who knows ' as last' ?

on ubuntu I installed a program that monitors temperature and speed ' fan :

the temperature takes a cycle every 2 minutes going from 40C - 90C- 40C etc. ..
clear that sooner or later, the expansion of the components does break some welding

the system should adapt to the load and stabilize the temperature , do not work this way.

Solder with lead melts at lower temperatures and it also solves the whisker problem. The lower melting point means it will induce less thermal stress on components it's applied to.

Using a machine that runs 24/7 as example though isn't good. Connections also suffer from thermal stress at each cycle. Meaning it's better to keep it running (warm) than have it cycle through cold and warm multiple times per day. That's why you will see such failures more in laptops, as they tend to be powered down for every short time period they aren't used. Desktop computers on the other hand are usually left on when not in use, or least have a much lower cycle count in general. If I look at my own desktop I turn it on and off maybe three times per day at best. My Thinkpad on the other hand...

aldimeola81 may be on to something, removing the plastic on the underside of the keyboard, in the area above the fan, should increase airflow, as the fan could suck air in between the keys.
But it might decrease ventilation in other areas, testing is needed, and I have a disposable keyboard that fits in a W510.

There is one annoyance to this mod, stuff that falls in the the keyboard, could end up in the cooler.

Hmm, unless some sort of filter was made...

Edit: yup air is definitely being sucked in through the keyboard, it's easy to feel it, I guess it will work then.

[Adda]

Yup seems to work just fine, more testing is needed but, it is hard for me to make the CPU run hotter then 80C and the GPU stays below 75C.

Edit: peak temp seems to be 86C, but more testing is needed, tomorrow.

[jcvjcvjcvjcv]

An increase in cold air inflow at the fan means the heatsink overthere gets cooler. The decrease in airflow in other parts of the system might very well be compensated by an increase in heat flow through the heatsink. But than again... not all parts are connected to that heatsink.

[aldimeola81]

I've done some additional mods, i've untested yet, here the pictures

Oh, you don't have the same cooler as me aldimeola81, there are two W510 coolers, I have the AVC one, yours is different.

[aldimeola81]

Avc? Post a picture of yours

[Adda]

Here is a pic of a W510 with an AVC cooler (AVC is the vendor) not my unit but a nice picture:

Here is a pic of a keyboard modded for improved airflow:

http://cdn.head-fi.org/9/9f/9f251ecd_AUT_9401.jpeg

Edit: this mod really works, idle temps are down by about 3 degrees.
I have configured IBM_ECW to power off the fan at 47C, and it powers off regularly if the system is idling, before the mod, the fan never powered off, and temps rarely got any lower then 50C (with my non standard config).

Mine cooler has that fru 60y5494

Which cooler is better in your opinion? Bye

I would have to make a direct comparison to say anything about it.

But it seems that the AVC cooler is the one that suffers from poor fit, I don't think your cooler model has that problem.

[aldimeola81]

@ adda :If you try to remove the heatsink and remount it as I wrote above, I think the temperature will drop even more.
Seeing is believing

[Adda]

I'm not quite sure about the reasoning behind the changes you made, could you try and explain it to me?

It seems you put a thermal pas between the cooler and the plate above it, and put some sort of thin thermal pad on the keyboard.
Similar thinking to the cooler in the T43p.

But what about the foil you taped under the palmrest?

I'm not sure I want to expose the bottom of my keyboard to the scorching heat of the 720QM.

You have understood well, don't worry about the keyboard, the thermal pads doesn't transfer very much heat, but it help to keep temperature down.

That alluminum tape is an attemp to improve the heatsink surface, not tested yet, i would keep the fan always stopped when i'm over ubuntu. This evening i will test it, bye

[Adda]

So I modded my main W510 keyboard (LiteON) it has bigger openings in the bottom plate.

Here is the result of a straight 20 minute 4x max heat Prime95 + furmark extreme burn:
http://cdn.head-fi.org/8/8b/8ba8e6dc_beforeburn.png

Here is a continuation of the test, but now I have put all the Prime95 threads and furmark on to core 3:
http://cdn.head-fi.org/1/1d/1d9fb20d_afterburn.png

Problem solved.

I have core parking enabled, so the CPU runs as fast as it can.
The GPU runs at 0.85v clocks are shown in the picture.
Fan speed at max (64).

not bad, but i think we can do better

[Adda]

I'm looking forward to seeing some more test results of your modded W510, if the improvement is significant, then we have another trick to use if the heat of summer proves too much.

W520 owners should do these mods and post results, right about immediately.

Can you do the test with both version of furemark and prime 95 for an hour as i've done after? So we can make a comparison.. Bye

[Adda]

That will have to be some other time, as I just finished running a half hour test.

Similar result to my last test, so this is really as hot as it gets, no other tests I have run will produce higher temps then this.

Quad core burn:

Followed by single core burn:

here is mine

please try the same test, otherwise we can't understand which way works better.

I'll try 'even your system in addition to mine, I want to see if I can go to 50C

Looks very good, I will have to get the other W510 cooler sometime, so that they can be compared under the same conditions.

Playing Borderlands 2, the GPU in my W510 stays below 60C, and the CPU stays below 70C.

So under normal conditions, the GPU stays between 47 and 60C, quite a narrow temperature range.

maybe now I can be happy, I have removed the metal sheet on the processor, it seems that finally the temperature begins to go well

[Adda]

You still have something between the CPU and keyboard right? only difference is you removed a layer?

[Adda]

I lined the part of the heatpipes that is exposed to the underside of the keyboard, using a thermal pad from a T43, cut in half (used both halves).
The pads are in a single layer, I removed that metal plate, I did not remove the plastic backing on the keyboard in the area above the thermal pad.

It seems temps has been lowered by 2-3C for both CPU and GPU, so the CPU doesn't exceed 75C, GPU stays below 69C.
I did not do a single core burn this time, I don't think it is necessary at this point.

[aldimeola81]

yes, i've removed a layer and moved the termal pads, i've added some thermal pads over the cpu and other over gpu.


you wrote that you've lowered the voltage of the GPU, how you do it? using ntune or what? bye

[Adda]

To undervolt the GPU first get "PowerMizerManager":
http://nvidia-powermizer-manager.software.informer.com/

Use it to force the GPU to stay at a constant power state, rather then dynamic scaling.

Max perf = 0.93v

Med perf = 0.85v

Min perf = 0.8v

You can set different power states for AC and DC, so why not put the GPU in to it's minimum power state when on battery.

Then get nVidiaInspector:
http://www.guru3d.com/files_details/nvi ... nload.html

Use it to overclock the GPU, remember to select the correct power state in the overclocking menu (P8 if you run at 0.85v).
Shader clock should be core clock x2.2, I don't recommend overclocking the video memory, just put it at 790MHz.
To apply overclocked settings at startup, right click the "create clocks shortcut" button and select "update startup task".

I think you can safely overclock to 575/790/1265MHz@0.85v (core/mem/shader), beyond that you'll definitely need to test rigorously to be completely free of artifacts or crashes (real world gaming, synthetic tests are better for temperature testing).

thank you very much, however I do not want to increase the clock frequency for the time being, I have already 'burnt my T61P so, then for now the power of the GPU enough for me.

if I set the voltage to 0.8 constants, there are problems?
