DO NOT buy y510p SLI! They are all defective !

2013-12-30, 22:01 PM

Okay, the title is not entirely true, and considering speed, this laptop is a BEAST, it is really cheap compared to other laptops with similar processing power, however there is 1 huge problem that Lenovo forgots to warn users about. 

 

The chassis of this laptop was designed for 2x 650M VGA and because of this the 2x 750M are having heat issues due to the higher voltage and clock speeds. The built in main 750M/755M is okay for most models (however many are factory defective and does not have thermal paste applied properly), however the Ultrabay VGA may be a deal breaker for many people.

 

The 650M in the Ultrabay can operate on relative acceptable temps (max 176F-185F/80-85C), however the higher clocked 750M (and also the 755M) with higher core voltage will reach 208F/98C in a matter of minutes and starts to throttle with GPU intensive games, like Crysis 3, Bioshock Infinite, Witcher 2, etc.

The reason for this is that the Ultrabay in this model was designed for 650M, which means:
a) The fan is too small
b) Technically there is almost no point where the fan could take in air, there is only a small hole at the bottom of the laptop
c) There is an aluminium casing inside, surrounding the Ultrabay slot which will eventually overheat and retain the heat

 

I have to note that even though the Ultrabay VGA reaches throttle temperature, the ultrabay fan will not start to work on maximum RPM, currently the only way to use the fans on maximum RPM is to use the dust removal service in the Lenovo software. Running the fans on maximum would help the ultrabay vga, but Lenovo does not allow it, probably because the laptop would be too loud and people would complain because of that.

 

Repasting the ultrabay vga will not do anything. A notebook cooler can help to lower the cpu and built in VGA temp, but it will not help the Ultrabay VGA, it only makes it reach throttle temp slower.

In short: A beast of a laptop regarding speed, however the Ultrabay slot is not designed to hold a 750M/755M and the VGA inside it will overheat with any game that utilize 99% of the VGA.

 

It is okay with games like Skyrim and X-Com EU, but Crysis 3, Bioshock Infinite, Witcher 2, etc will fry the Ultrabay.

 

There are 2 things that Lenovo could do to lower Ultrabay temp and do not loose performance and also these fixes are only changes in the software and anybody could apply them at home. What are these?

1) Increase the Ultrabay fan RPM to maximum, why is the fan only running on max when the dust removal is operating? Why does it let that poor VGA burn? -> Simple BIOS update for the system

 

2) Lower Ultrabay, 2nd 750M/755M VGA voltage, this could mean -50-60 F (10-15C) and  the vga would perform the same in games and benchmarks. This fix only needs a new vBIOS for the 2nd VGA

 

Both fixes could be made by Lenovo in a matter of hours (counting the time Lenovo would need to test the lowest stable voltage for the 750/755M), so why aren't they released yet ? Is is better for Lenovo to let the Ultrabay videocards burn and give a complete new ultrabay vga for their customers? Wouldn't making a new BIOS/vBIOS be cheaper ?

 

(BIOS and vBIOS are locked so users can not modify fan speed or change voltage)

 

Please keep the above mentioned in mind when you purchase an SLI y510p.

That is if you can get your SLI ultrabay card to work! Anybody that bought a single 750m version Y510P and then later on bought the ultrabay 750m5 card as an accessory cannot get the cards to function at all. The only way to get them working so far is to ship your entire laptop back to lenovo and have them do a bios update and a few other tweak.

Did those people also purchase a 170W power adapter for the ultrabay card or they tried with their default 120W adapter?

What if you use a fan pad under the laptop ? doesn't it do the job ? because i'm buying the Y510p soon and now you make me confused about it...

I curently have a 10-c temperature different between 2 gt755m while running AC4BF, the ultra bay is the hotter one.Is this normal?

Is this problem really as bad as these people are saying it is.

 

You usually hear on forums more problems than good things. Can anyone reading this confirm that they aren't having the same problem or have found a way to keep it managable?

 

I bought this laptop over the weekend and have just found these posts on here - not too happy!

I can confirm that the ultrabay gpu run extremely hot. I just bought a cooling pad called cooler master U3 because you can put the fans (there are 3) wherever you want so it will porbably make it run from 10c to 20c cooler, also you can clock down the gpu with evga precision and disable the i7 turbo, which is an overkill for most games.

When I get my new laptop I am temped to repaste the ultrabay GPU and maybe even try the mod where you cut open the bottom more to let better airflow. I also undervolt my CPUiGPU/cache to help with temps (it works great on my single card version).

Welllllllllllll

 

What's the point of making a laptop that doesn't work properly. Do they not test them when they design them?

 

 

 

 

So what's the fix then? So far i've seen -

- Making a hole in the laptop

- Modding the Fan settings to spin faster

- Less voltage to GPU

- Turning off Turbo in the i7 processor

- Repasting the GPU

- Using a cooling pad (which only prolongs the issue)

 

All things (except for the last point which isn't really a fix) which I'm not prepared to do my self as I will most likely break something.

 

How difficult are these modifications to the BIOS/Settings? Is there a guide or a site that talks about altering these types of settings?

 

I'm yet to take delivery of my new laptop and was hoping that splashing a few extra hundred pounds into something half decent would rid me of any problems and give me extra power to play with. I originally considered a safe i5, Intel 4000, 4GB option for around £500 but wanted to splash out a little bit.

 

These issues are now making me worry and pushing me to consider cancelling my order before it's even shipped out to me.

 

WAaaaaaaaaaahhhhh :(
