Y500 GT650M Overclock

so i played a little bit and from the basic settings with score of P3676, I pumped it up to stable score of P4176 . i used theese settings

how did you get the core clock so high? my is locked on +135 MHz max , and you have it on 435. pls answer. thx

 

His GPU must be really good at overclocking. Everyone is different.

 

I messed up my laptop tonight just before work. I re-pasted my laptop yesterday to IC Diamond 7 and decided to run Furmark at 1155/2555 to compare to my temps with AS5. Things were going well and then I noticed the screen flash, I stopped the test and a few minutes later the screen blacked out. I was like, sh!t.... Temps were looking good when I stopped it, it had just past 80C but the palm rest was burning hot. I didn't have my fan turned on on my cooling pad. Worst case, I might have loosened some solder on the MB which will require me to bake the MB. Best case, and I've already disassembled everything but had to come to work is that some of the left over AS5 might be conducting on the GPU because I didn't clean it around the core and some of it had seeped under the clear plastic sticker that is around the core. The laptop still works fine, the hdmi out works fine and the damnest thing, and how I know it is not the display or the lcd inverter. I ran Furmark and around 60C, the laptop display came back on. I let it cool down and the display turns off again. So, from my troubleshooting, I might be sticking the MB into the oven. Hopefully I won't have to, and cleaning the AS5 off the GPU completely will fix my issue. Beside that though, I'll also have to say the IC Diamond is no joke, no improvement over the AS5 at idle but under load, it performed much better. It maxed out at 87C for a 15min burn-in 1080p full screen test with the 1.1v bios. Where as before it would throttle at 97C. I used the pea size drop method or whatever it's called.

 

Man sorry to hear that n1smo! Hope everything works out for you and you get a working laptop again in short order.

I remember you saying that the stock factory paste looked and performed like AS5. I've never used AS5, but if what you say is true, then other ones like ICD and OCZ Freeze definitely perform better. I just took my laptop apart for the first time a few days ago and repasted everything with a mixture of ICD and Freeze. I used ICD on the Ultrabay and Freeze on the CPU and GPU. At idle temperatures haven't changed but at load the CPU has dropped 10C and both GPU's have dropped 5C.

 

lenovo botch my order they sent me the 120 w att adapter for my sli machine

i am currently using it to power the machine sli overclocked via 1.1 voltage mod
i am at 1190/2500 i was told to look out for abnormalties because of the low power

what abnormalties should happen
i see fraps reporting games over 60frames but they move like they are at 33 frames sometimes is this normal

please elaborate

 

Thanks for the condolences, I baked the MB today and still a no-go. Even worse now, as running Furmark doesn't bring the display back to life. I'm thinking the next thing to try is to buy a new LCD cable as that is the cheapest thing to replace. I have a feeling I'll need a new MB though. Right now, the laptop is attached to my 52" LG LED TV and it looks pretty damn good actually but still need to eventually fix this thing as is now a desktop. Of course my summer courses starts tomorrow and I'll have to do my homework on the big screen. LOL

After I baked the motherboard today, I used AS5 instead of IC Diamond because I only got the little tube of the ICD and want to save it until I've fixed the issue. However, I applied the AS5 with the same technique as the ICD and guess what? The temps were the basically the same. So, pea size drop method is the way to go apparently. I used to smooth out the compound evenly over the surfaces with a plastic razor blade.

 

I'm surprised you are able to run sli 1.1v overclocked off the 120w PS. It would immediately give me a driver crash (crash back to desktop) when I tried it. You've got a very strong 120w PS, maybe they mislabeled it.

 

here is a pic of the power supply



also how did u get that score of 5200 in 3d mark the most i get is 4680

 

LOL you should never spread the TIM before putting on the heatsink. That's guaranteed to trap air bubbles and degrade performance. Putting a pea-sized amount on the center of the die and pressing the heatsink down, maybe wiggling a little to facilitate spreading, is the best application method as it creates an airtight seal. The TIM spreads out evenly once it's heated up.

That's definitely the 120W charger.

His score is due to his overclock being slightly higher than yours. But you should still not be getting that low. Even I got P4900 at 1120/2250 stock volts. Your low score could be due to overheating and subsequent throttling, not enough power supplied by the charger and subsequent throttling, or VRAM clocked too high.

 

hey octiceps i am not using throttle stop just the overvolt mod at 1150/2500
so is that score normally for that setup

 

No it's low. Even if your CPU was throttling you shouldn't be getting that low. Read my previous post and check where the problem is.

 

Hey man, thanks for providing us with this guide but i am having a few problems. Firstly, i am new to overclocking so i don't really know what i am doing, but i figured id try it out seen as you already had the batch files made and it was working successfully for you. However, since overclocking for about 5 minutes my Y500 has become a lot slower. I have restarted my computer several times and now when i play games at stock speeds i am only getting about half the fps that i was getting before i overclocked using your batch files. Do you know any reason why this could be happening, it doesn't make sense seen as i only overclocked for about 5 minutes and my y500 is less than a week old. If you have any idea what the problem could be please let me know.

Thanks.

 

HELOO Where shall i put the bat files ? Just in the same place as the nvivdiainspector i located?

 

HEY GUYS I Just downloaded the latert drivers and change the bat files to @echo off
c:

cd "Nvidiainspector\"
nvidiaInspector.exe -setBaseClockOffset:0,0,135 -setMemoryClockOffset:0,0,250 -setGpuClock:0,2,1050 -setMemoryClock:0,2,2350 -forcepstate:0,0

||-forcepstate:0,5
||-forcepstate:1,5

and it works fine no vbios mod or anything and i scored this 4434 on 3d mark 11

 

Well finally got around to tinkering with my OCing.

I've got the 650m SLI Y500 v2.02 BIOs with stock voltages.

Card 1 - Internal:
ASIC: 81.1%
Core: 1150
Mem: 2220

Card 2 - Ultrabay
ASIC: 61.9%
Core: 1050
Mem: 2220

3DMark 11: P4646
Heaven: 454

Temps not past 70C usually.

I've concluded that it's a great performance increase overall, but clearly the ASIC quality of my Ultrabay GPU hinders the overall potential of my overclock. Maybe I can try to get another...

Still happy, and definitely noticeably smoother in more intense games.

 

How do you overclock? Everytime I try too overclock my PC craches or I simply fail.

 

You need to set the clocks respective to your gpu voltage.. you need to overvolt for more overclocking. But it may some what risky. Heats your gpu and may burn it if u volt too much.

Guys, I got my Y500 750M SLI few days ago. I updated the graphics driver to the latest on the Nvidia website.

Regardless turning SLI on or off in the Nvidia panel, I am only still getting P2xxx score. I tried to adjust the PhysicX option as well, no use. The cause of the low score seems to be at the PysicX test, where I only achieved 2.5FPS.

I have done test with games and I am certain that both cards are working. The usage showing is 90%+ for both cards.

Is this a configuration or driver issue?

 

Which version of 3DMark are we talking here? 3DMark 11? 3DMark (2013)? It would be helpful if you provide a screenshot of your scores as well.

The Physics test is not the same thing as PhysX in the Nvidia Control Panel, don't get those two mixed up. The 3DMark Physics test is a CPU test while PhysX is an Nvidia proprietary GPU-accelerated physics technology. Turning PhysX on or off has no impact on 3DMark scores whatsoever since it does not use PhysX.

What is your actual Physics Score? Example:



2.5 FPS doesn't tell my anything, although that sounds way too low if we're talking 3DMark 11. I average 24.4 FPS in the 3DMark 11 Physics Test with my i7-3630QM:

 

Thanks for your reply. It is 3dmark11 that I am talking about.

I will have to go home and run the benchmark again to show you. OK, I get the Physics test now that it is unrelated to PhysX.

So it sounds like my CPU is not throttling when the test is running? I am constantly getting 2.5-3 FPS.

 

Found the problem. Compatibility mode was ticked. After removing the tick, everything is working perfectly.

I'm having a problem with overclocking on Y500 650M SLI using Nvidia Inspector. For some reason I can overclock my memory but not the base clock.

Here a screenshot on gaming load: http://img.techpowerup.org/130727/nvidia_20130727_195546.png

 

If you can't be bothered to read what other people have posted then nobody is going to assist you.

This issue is known and has been addressed multiple times.

 

Recently overvolted my GT 650M SLI and got P5228:

NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID

Clocks were 1260/2250 @ 1.137 V. Stock is 790/2000 @ 1.000 V.

Currently sitting at #3 in the standings for this particular configuration. The score would probably be a little higher if I didn't use such an old driver (314.22 WHQL), but whatever. I'm only running these speeds for benchmarking purposes as it's impractical for everyday usage due to the heat. If I fire up a demanding game such as BF3, both GPU's reach almost 100 C within 15 minutes and begin throttling. I already cleaned out my fans and repasted, plus the laptop was sitting on top of a cooling pad, so the laptop's cooling design simply cannot cope with the extra heat. 1120/2250 @ stock volts is my everyday clocks and I'm very satisfied with the performance boost.

 

That's great!

The more I read about the new Y510p and the the Y500 with the GT750, the more I'm happy with my Y500 GT650. It's solid, it hasn't given me any trouble yet, many small upgrade paths (msata, ram, optical, hdd). The Y510P, while having some benefits, just doesn't work for me with the NGFF slot mainly.

The only thing that is bothering me is the 62% ASIC on my Ultrabay card. Siiighhh!

 

Don't worry about it, just be glad you got an Ultrabay at all before Lenovo stopped selling them except in SLI configurations. A lot of people are wanting to upgrade to SLI but are unable to do so now because of this fact.

Now that I think about it, I'm not so sure GPU-Z's ASIC quality reading is entirely indicative of overclocking headroom. Case in point, when I got my replacement Y500 my internal GPU reading went up, from 73% to 78%, while I kept the same 84.5% ASIC Ultrabay. I wasn't able to goose a higher overclock out of the replacement unit, still at 1120/2250 like my old machine, because it was the Ultlrabay that was the limiter. I verified this when I disabled SLI and overclocked just the main GPU and could get higher than 1120/2250. I would've never thought that the Ultrabay, with its higher ASIC reading, would be the limiter but it is.

 

hi all,

i managed to overclock my Y500 with SLI GT650m to 1100/2500 WITHOUT modding bios at stock voltage.

Why must some people use the modded bios to overclock?

 

What driver are you using and what overclocking program?

 

Because it lets them overclock past the +135 MHz core limit without using .bat files and gives them voltage control and because the Nvidia drivers after 310.90 simply don't allow you to overclock at all with this method, or so I've read.

 

That's fair enough. The fact that I can clock them asynchronously does make it better than nothing at all.

I'm also glad I bit the bullet on the SLI card when I had the option, it helped that it was on sale. They weren't selling pre-configured SLI models in Canada at the time.

 

i use beta 326.19 drivers und Nvidiainspector with bat. files.

run with 1100/2500

no modding, no overvolting.

:rolleyes2:

 

Hi all, I am running SLI 650m with modded bios (y500) Can someone tell me why, when I use MSI afterburner to add 100mhz, the increase shows up in inspector as 975, gpuZ as 935 but when I test in Heaven, it shows as 890? all 3 show my stock as being 875.

 

can anyone post a link to the modded BIOS for SLI?

 

For the Y500 GT650 and GT750 models it is here:
Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Need to sign up at the forums and have 5 posts before you're able to download the required files. svl7 is a genius.

 

thats exactly why I wondered if anyone had a direct link or something.. but I guess I'll have to make 5 posts then

 

Well people have already gotten in trouble for sharing svl7's work without his permission in the past, so anybody giving out direct download links is not doing so in good faith. Anyway, go check out their place, you might enjoy your stay. The discussions about this laptop are a lot more technical over there than here if you like that sort of thing, and I've learned a lot.

 

Really? that sounds awesome, I was looking for more tech/laptop forums, thanks for the advice!

 

Joined just to share my OC tests.

I managed to get up to 1000/2200 with a 513 heaven score, min 6.5 max 47.3 fps

Really good considering I've seen lower scores for higher OCs

but the problem is my onboard GPU runs @ ~64 Celsius which is nice, but the ultrabay GPU max temp I've seen is 79 Celcius playing Far Cry 3... Could have gone higher.

Should I be worried?

 

Your score is higher because you are running Heaven at lower settings. I use all the settings maxed out like so and get 475-485 at 1120/2250 clock speeds.



Your GPU temperatures are nothing to be worried about at all. The 650M begins to throttle at 97C and you're nowhere close. It's perfectly normal for the Ultrabay GPU to run up to 10C hotter than the main GPU. Both my GPU's run at 70-80C all the time in demanding games.

 

Thanks for the reply! Actually, I've run heaven at the exact settings you provided. Here is the results screen:

http://i.imgur.com/eWP6M5S.jpg

 

Huh...that's really weird. So you have the i5 version and Windows 7. Could the big difference be due to Windows 7 vs. Windows 8? Or maybe Heaven is acting weird?

What is your 3DMark 11 score? Here is mine: NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID

I know you have the i5 so the Physics Score and overall score would be lower, but I'd be interested to know what your GPU Score is.

 

Sure. I will post the results when I get home.

 

I got home and ran a few tests with different frequencies.. Seems like the sweet spot is 1000/2200 for my Y500.

Here are the 3DMark 11 results: NVIDIA GeForce GT 650M video card benchmark result - Intel Core i5-3230M Processor,LENOVO INVALID

My ASIC scores are 80.9% and 64.4% for the onboard and ultrabay, respectively.

Are these good results? What would you say the GPU performance is comparative to, card-wise?

Thanks for the help!

P.S - I went higher in frequency and saw lower scores. I read that that means you should stop clocking higher. Is this a hardware limit or is there anything I can (safely) do to get some of the clock speeds that others have gotten?

 

That result seems normal for your setup and clock speeds.

As far as what desktop GPU this compares to, it's hard to say for sure, but based solely on 3DMark 11 Graphics Score it's similar to GTX 560 and 650 Ti and Radeon 6870 and 7790.

The reason you saw lower scores as you increased the clock speed is due to the VRAM. GDDR5 does not crash when it is pushed past its stable limit, it just experiences decreased performance due to error detection and retransmission. This means that when overclocking GPU memory, you need to use a scored test as well as look for the traditional signs of instability, e.g. artifacting and flickering.

Overclocking the core is simply a matter of pushing it until the display driver stops responding or your system shuts down. Then back off a little until it's stable again.

You should try to see if you can get the core any higher than 1GHz without crashing. After that, you need to increase voltage, for which you need the modded BIOS and Ultrabay vBIOS. You need to take necessary measures to keep the notebook cool, such as repasting and/or using a cooling pad, as even small increases in voltage will shoot temperatures up drastically. You also need to know what you're doing as this not the safest thing to do for the lifespan of your GPU in the long term depending on how hot and how far you push it.

Personally, I am running 1120/2250 on stock voltage. For a 24/7 overclock I would suggest finding your highest stable speed without touching voltage.

The ASIC Quality numbers on my main and Ultrabay GPU's are 78.0% and 84.5% respectively. I'm pretty sure this is meaningless as far as correctly predicting overclocking headroom as my Ultrabay GPU cannot go as high as my main GPU when I overclock them individually.

I only used Unigine Heaven for stress testing when I overclocked my GPU. Don't use the synthetic fur-rendering programs like FurMark, MSI Kombustor, and OCCT. They're good for heat testing but pretty much useless as stability tests for overclocking and are likely to damage your GPU if used a lot.

 

Thanks for such a great reply. I had the system at 1100/2250 I believe, and mid-heaven the screen went blank. Not being able to ESC out or anything, I panicked and just shut the system down. I haven't tried since, worried about the health of my cards.

I'm assuming that was because it was clocked too high, but there might be the off chance it was just a one time thing. I doubt that though.

 

Yeah when the display driver crashes like that it means the core is too high and you need to restart the system. I went through a bunch of that before finally finding my stable limit. I went up in small increments. 20 MHz at a time for the first 200 MHz, 10 MHz for the next 100 MHz, and 5 MHz after that. Stress test in-between every increment of course. It took a lot of time and testing but I finally found my limit at +330 MHz. Then, same thing with the VRAM while keeping the core overclocked. If you reset the core and push the memory as far as you can by itself, you'll find that when you put the two together it won't be stable, so I always keep the core overclock in place when doing the memory. It's pretty easy to find the limit on the VRAM because my Heaven score dropped by 100 points when the memory was even 10 MHz over its limit.

 

Hello, I'm using the 327.23 drivers with my Y500 single 650M, MSI afterburner only works increasing the Memory, but not the core, so I'm stuck with Inspector .bat files. They do increase my clocks, but when I switch back to default settings, the clocks remain at maximum speeds (790/1000Mhz). Is it possible to switch it back to true defaults that scale back the clocks depending on load (except restarting the computer of course)?

I wouldn't mind if it worked with Afterburner even for the +135Mhz, I just need to have an option to switch back to basic clocks and dynamic scaling.

 

Hello N1smo, your guide is awesome and I have been following this thread since 2 days. I had my lenovo y500 a year ago and since I am not so good at computer, I only realized I can unlock the full potential of my sli gpu by using nvidiainspector. I just did a 3d11 test for my gpu and I only get a measly of 2600+ for Firestrike demo in unclock state. A few weeks ago, I was using my MSI afterburner as the overclocking method.

I have two questions, those bat.file you have posted can only be used after you flash the bios?( Not sure if it is the correct term) Because when I tried to manually adjust to 1100/2500 in p5 state, it just resets back to 135/405. However, I can use your files perfectly and I only realize that the files are used for P0 state?( not sure)

Another one would be, since I have two gpu, do I have to create another command line for my 2nd gpu? I tried the read the link you gave to me but they never seems to give an example or I am just plain stupid :/

If you are kind enough, can you share me your latest .bat files?

 

I also have the GDDR5 version of the GT650m, right now I am running it at 1190MHz Core and 2280MHz Memory. Does anyone know if I need to adjust the Core Clock Offset? I don't know how to explain it but if you look at the screenshots you will see that the Base Core Offset is at 0 when it could be pushed to +135 but I'm not sure if that will have any effect at all since the clocks have been forced by the batch. Thanks a lot guys any advice would be appreciated.

Please can someone check if my batch command is correct:

C:\Users\Y480\Desktop\OC\nvidiaInspector\nvidiaInspector.exe -setBaseClockOffset:0,0,0 -setMemoryClockOffset:0,0,0 -setVoltageOffset:0,0,0 -setTempTarget:0,1,91 -setGpuClock:0,2,1190 -setMemoryClock:0,2,2280 -forcepstate:0,0
