Well regarding 755m driver, dont even bother because it wont work as y510p have optimus and MAC OS X dont support it. They have their own implementation similar to optimus but its not same its called Iris. So you will need to remove ultrabay card. So far only integrated intel graphics works a bit. They use 755m in original macbooks but its their own MAC version and it wont work on ours unless you somehow make it detect as mac version. SLI wont work at all.

I used GELID GC-Extreme and temps difference is 15 C degrees, and if undervolting, even 20 C degrees so it was worth it. To get to main gpu and cpu you have to dissasemble pretty much whole computer . Just follow the video you posted and you will be allright. PS: It took a day or two for paste to get optimal effect but you can turn computer straight after repaste. So far I am happy with this thermal paste. Just dont miss out any cooling pads when you take off heatsinks.

Did you tried modified bios aswell? Well you have bought non-sli version then probably. They should at least tell you if its going to work or not. Cheeky bastards those lenovo technicians. If modified bios is not going to work then you might be out of luck. I bought 755M SLI version . I was in temtation to buy it separately but I was lucky that I spotted great deal on this model in my country so I bought it cheaper than lenovo sells it. It was however DOS version but I can install clean windows myself without any crappy preinstalled software as manufacturers do them. If you really have non-sli version then you are out of luck as non-sli versions are probably not able to deliver enough power for second ultrabay vga. Even if you have got 170W power adapter. Sorry but you better sell that laptop and that card for whatever you can and buy SLI version with ultrabay card.

I have only Windows 8 Installed so I cant say really much but I would rather download latest nvidia drivers directly from nvidia website rather than third party. You can set Nvidia Driver Experience to notice you about new driver updates and if you want you can set it to download it automatically whenever new driver is released. Geforce Experience will let you know when driver is ready to install. I dont know if it can be set to automatically install it but its better to install it manually by opening Geforce experience and hit install button as before you install new drivers you can read changelog of new drivers and decide to install it or not if you are not happy with it for some reason. All other drivers can be downloaded from Lenovo website directly, and in most cases its best to download it from official manufacturer unless for some specific reason you want to install drivers from different source. I dont really have a good experience with automatic driver downloaders from third party so I cant recommend you any at all. I let Windows download it itself via Windows Update if there is any new driver update offcourse approved by Microsoft. Any other drivers I just check drivers every month or two manually by visiting manufacturers support website. You also mentioned that you boot SSD with legacy, so you are saying it does not detect ssd if you select uefi only? Even in bios? Regarding previous question about downgrading to older bios. I dont know if its good idea as I personally feel better performance under v3.05 rather than older one, but I understand that some people just want to revert back to older. After you select Bios Flasback option and set it to Enable in bios. Now go to Windows and go to: http://forum.techinferno.com/lenovo-ibm/4668-lenovo-y410p-y510p-unlocked-bios-wlan-whitelist-mod-vbios-mod.html There is a stock firmware v2.07 in step 3 so you just have to download it, unpack it and run it as administrator. This will downgrade your bios. Make sure you have battery in, all programs closed to prevent bad flash. It will probably ask you to restart the computer or it will do it itself I cant remember but anyway after restart dont touch anythink yet and let it flash the bios. It may turn off for couple of second and then it may turn on itself, if not just start it and load bios and load default settings. After that you are good to go. Hope this will help you.

what SSD do you have? It shouldnt cause problem on latest bios. Try to put back original hdd and reflash the bios again. If you want to revert back to previous bios version, select Bios Flashback option in Bios. Then flash older bios v2.07. If problem still persist, it may be due to faulty SSD. I know they are not cheap but investing in quality SSD will bring its fruits. Did you tried it on other PC? Try it if you have spare one to see if it do any trouble on other PC. If it does it again it may be faulty SSD. It looks very dodgy that SSD cause bios to freeze. Also set SATA to AHCI mode if you havent done it allready. Maybe thats the culprit :). If you installed Windows in IDE mode you will have to go to Safe Mode after you change SATA to AHCI and when booted in Safe mode fire up regedit and find following entries[FONT=arial]HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci [/FONT][FONT=Segoe UI regular][FONT=arial]HKEY_LOCAL_MACHINESystemCurrentControlSetServicesIastorV[/FONT] [/FONT]On the right side right click on Start in Name column and click modifyType 0 in Value and save it. Restart and see if it works.I fixed it like this when I stupidly installed Windows in IDE mode instead of AHCI

Whats the version of original unmodified version of your bios? If you have old bios try to download official bios update from Lenovo and also download vga bios update from this thread. Its second post. Make sure you pick 750m bios. Just follow the instructions. If it will fix your issue I dont know but you can try. Where did you bought your laptop and second vga card? Edit: http://support.lenovo.com/us/en/products/laptops-and-netbooks/ideapad-y-series-laptops/ideapad-y510p-notebook/documents/HT079946?tabName=Solutions Thats the official fix from lenovo as I said before, you have to have updated bios and also vga bios. You can download original bios from the link above. If non above worked try modified bios. And if it still dont work then speak to Lenovo technical support and ask them for help.

Hi. Did anyone attempted to solder new bios chip after bricking? I have seen that some company is selling bios chips for our laptop. I am probably going to buy it. I havent bricked my laptop(jet) but just in case it happens I will have those chips. BIOS Chip:LENOVO Ideapad Y510P (Dual chips) | eBay I have also seen other seller but its for Y510, they look same but I dont know if they are actually same, as they come preprogrammed already. Lenovo IdeaPad Y510 (15303) Bios-Chip24.com Also I am looking forward to buy this programmer if the chip will be compatible. I contacted the seller that I want to make sure what is the part number for bios chip of our laptop. I am too lazy to dissasemble my laptop again to look what part number it is http://www.ebay.co.uk/itm/SPI-Flash-Programmer-WINBOND-ST-PMC-MXIC-ST-SST-ATMEL-/290587546215 Edit: It seems like chips in our laptop are Winbond 25Q32FV and Winbond 25Q16DV And they are pretty cheap to buy on aliexpress.com even if you buy them in bulk so in any case cost of chip plus programmer is cheaper rather than sending it to lenovo. I ordered one of those chinese programmers. SP8-B SPI Programmer to be specific as it supports the chip we have in y510p and tommorow I am gonna order chips. I have to buy 10 of each but they are cheap. At least I have spare ones just in case.

Okay so I updated microcode to bios file and also set CPU_Microcode to 1 in platform.ini. Nothing is modified except microcode updated to newest version. Here comes the scariest thing. I have done some little research how to recover semi-bricked y510p so I tried different names. I unpacked bios file from official bios flasher from lenovo website and put it on USB formated to FAT32 and renamed it to Yx01.bin, as Andys tool reported that recovery file should be Yx01.bi? but ''?'' is not permited to i changed extention to bin, as .fd, .rom didnt seemed to do anythink. So I took battery out removed AC adapter and pretty much everythink connected to computer, inserted USB and Hold Fn+R then plugged in AC and after that quickly Power button and it seemed like its doing something but computer shut down immediatelly so I dont know if it did anythink at all. Maybe it ignored it as version in my bios is same as bios file is and its not modified bios. Can someone confirm that this method of recovery works? Just in case I fail with flashing or anything goes wrong. Edit. I also noticed that when I updated microcode first when i checked bios file with intelmicrocodelist.exe to see what cpu ids are in the bios it gave me 2 results: CPUID=306C3 Rev 12 2013/07/02 CRC=D141251C Off=4C9330 Size=4C00 Plat=1, 4, 5 CPUID=306C2 Rev FFFF0006 2012/10/17 CRC=30531EB4 Off=4CDF30 Size=5800 Plat=1, 4, 5 after modification second line dissapeared, I havent found anything with that cpuid on internet at all so I dont know what that ID really is. Dont flash file in attachment its for research purpose only!!! Y510P v3.05 Updated microcode.zip

Yep, you have to dissasemble whole computer to repaste CPU and unfortunately you will void warranty as you have to take out the keyboard and screw thats holding keyboard is under Lenovo sticker that is hard not to tear. I tried to take it carefully but failed unfortunatelly . But I dont really care about warranty as I usually brake warranty sometimes next day I get somethink . I watched video to see how to dissasemble it. You just have to make sure you dont miss any screws as somebody reported that it may not turn on if there is any screws missing especially for keyboard. I lost one screw that holds bottom but it dont affect it fortunately.

Well what I did when repasting I cleaned what I was able to with nail polish(yeah I know, but that was only thing I had at that moment), leaving the old paste beneath transparent plastic around the chip, put the paste around the size of two rice seeds and put back heatsink vertically trying not to move heatsink too much over the chip so paste will spread nicely over the chip. Too much paste is not good, not enough paste aswell so I made first try just to see how it spread accross heatsink and chip, on second attempt I had an idea how to apply it properly. Also I made sure cooling pads were in place where they supposed to be. Intel XTU wont hurt your CPU unless you really do stupid things . I tried to set mutiplier to 36 and after few minutes computer just turned off but it didnt damaged anything, it actually suppose to do to prevent damaging CPU, overclocking it in bios is however risky as its gonna be set permanently until you change it. Thats what differs from Intel XTU, software itself is going to overclock your cpu once you start the program or during start of Windows. XTU will let you change what you can change in order to not damage CPU. There is also somebody in modified bios thread who claims that he turned off throttling of CPU in modified bios, but I am not really happy with it as its gonna raise temps up again and I would rather set settings down in game than have a portable cooker, heater and computer all in one . Its called Intel CPPC or Intel Collaborative Processor Performance Control. Regarding Ultrabay GPU I have 755m and I just undervolt it to -112.5mV nothing else really. You can use MSI Afterburner aswell. I use nvidia inspector for now until I get stable values I am happy with to settle. I dont know if its good idea to overclock GPU itself to get higher clocks as our gpu is running to its very limits when you take into consideration actual temperatures so what we can do is to just shave a bit of degrees down. I am not experienced overclocker, so dont take my words if you dont want to hurt your PC, but thats what I do to cool down computer a bit and its stable so far for me and I am happy with it. I am also looking into updating cpu microcode to newer one as our bios have not been updated with new microcode for our cpu. Allstone made a thread about it couple of months ago and I managed to find where microcode is located in our bios but I need somebody more experienced to confirm if its safe to update microcode via hexediting bios file. I read that people with different computers with Isyde Bios successfully updated their bios microcode with newer ones but I just bought this laptop 4 moths ago and I dont want it to brake it . Attachments are broken.

I am going to flash modified bios to test it out. So now we can disable throttling semi-official way .

I am not the one but if you flash modified vbios and fire up for example nvidia inspector, hit overclocking and there you can undervolt your card, I am at -112.5mV as allstone is and it runs stable at latest drivers. I am also undervolting CPU with XTU TO -70.3125mV(I cant feel any difference but it shaved a bit of heat at least) But you can try overclocking yourself with XTU and if you go to hwbot portal and compare your score and try profiles with higher scores. Also make sure you repaste it properly because if you dont do it properly and there is some place not covered properly between heatsink and cpu or gpu its going to make a difference.

If you install Ubuntu in UEFI mode ubuntu must install its boot files to EFI partition. Mine is under boot option in Boot menu when hitting F12 and also when it boots to grub it gives me option to boot to Windows. Thats out of the box after installing Ubuntu. No post installation of Grub or whatever. I used Rufus USB creator to create UEFI bootable installation of UBUNTU. No need to switch to legacy mode. At least not with latest ubuntu.

Hi allstone . I have done a little research and it seems like microcode is stored in bios for sure. Take a look at those picture. Comparing header of microcode for our CPU with Bios. CPUID of our CPU is of revision 000306C3h and that match with the header of updated microcode. Note that 1C is revision number of latest microcode. Also see that revision number in original Bios is different so we see that downloaded microcode is newer from ours. I used microdecode.exe to decompress all microcodes for all different types of CPUs, as we only need one particular microcode for our CPU. microdecode.zip Just drag and drop downloaded file with microcode from Intel and it will give you loads of file but we only need one so if you search for file with CPUID of our CPU and that is 000306C3 you will find that file. In latest Microcode update there is only one for our CPU in latest update. If you take that file to Hex Editor you can find the CPUID in the header of microcode,its in little endian so you have to convert it to big endian as shown in pictures. It also states the date but its not important for us, just a note so you know what first line is all about. Then I used search function to find where microcode in our original bios is, so I searched for our CPUID with little endian C3 06 03 00. As you can see now where our microcode in bios rom file is hidden now there is only one step to do and it is to replace current microcode with new one. I copied whole microcode that we decompressed and I Paste Write the whole code in the line of our bios where previous microcode begins, as you can see it in the pictures. Microcode for our CPU is only 4Kb. Saved the file but I havent flashed it yet as I dont know if its going to work, at the moment I dont want to brick mobo as I need it for work.

I run Ubuntu normally in UEFI mod, at least I have UEFI only mode turned on in BIOS at it works normally. I used Rufus tool to make USB bootable in UEFI. I dont know about other distros but Ubuntu worked well for me. I suggest to make bootable USB with this handy tool called Rufus that formats your stick to boot in UEFI mode. Really easy to use as I tried many other tools to make USB stick bootable in UEFI and Rufus so far is big timesaver.

Biggest bottleneck in Hackintoshing Y510p is Optimus Technology as Mac OS X dont support such a technology, well they have it and its called Iris but they use their own implementation(as usually, its Apple), but at least until now I havent seen any working hackintosh with Optimus technology. So far I was able to get past having Intel Graphics working, you also have to change wireless card from intel one to some other that is working well in hackintosh. As for now I need stable system so I abadoned experimenting with hackintosh, until I get my ultrabay hdd caddy I wont even try as best way is to install Mac Os X on separate drive. If you need stable macintosh you should buy Apple computer, but if you are experimental personality, go ahead but dont expect much. Also regarding haswell you have to patch mach_kernel in order to make it work. There is a tutorial around internet how to patch mach_kernel for Haswell processor. Regarding SLI, no way to make it work.

I play BF4 and Watch Dogs aswell and 3 months ago I was experiencing same crashes but after I updated Nvidia drivers to newest now 344.48 and also flashed modified Vbios for Second nvidia ultrabay card, it stopped doing this error. Even before I repasted both graphics chips and processor it stoped crashing, after repaste, highest temperature while playing in SLI mode is 85 on both cards, processor temp is 90. I also changed screen refresh rate to 80Hz and it runs really good.

Yesterday I have received GELID GC-Extreme Thermal paste and I must say I am impressed. I was worrying about funtionality of my y510p after I repasted as I havent done it before. I usually played BF4 on medium settings but still heating issues were causing lags and temperatures ranging from 90 to 98 degrees but after I repasted CPU, Main and Ultrabay GPU 755M SLI my temperatures dropped, ranging from 75-85 sometimes 90 and settings havent been changed in BF4. Playing experience is surely better than on stock thermal paste. When idle temps are pretty much same as before, sometimes I find it higher or maybe its just me being paranoid. Lenovo should invest in better quality thermal paste for sure. I was scared when I received my laptop and started playing and temperatures so high that I didnt needed heating to be turned on in my room when it was cold outside .

Now I have found out that it is probably inside bios and only lenovo can update it but some people mentioned that It might be able to load it from bios since latest microcodes are not small anymore but again it is probably done by microsoft when it decides that it needs to be updated. CPU Microcode? - Page 2

I am not an expert but its more likely that microcode update is probably inside bios. At least it used to be in some older computers/bioses. But I dont know about UEFI. I have read that microcode updates are also loadable/updatable via OS for example Microsoft pushes sometimes an update with newer microcodes. There have been some topics on other forums that best way is to buy brand new recently manufactured CPU that most likely have updated microcodes but it dont actually have to be like that with every CPU. Intel/AMD dont publish documentation about microcodes at all. There is some documentation around internet how to apply microcode update in Ubuntu but what it does I dont know. I havent tried it. I will try when I have some time and I will test it if it applies microcode permanently in Ubuntu as Windows is reporting that newer microcode is available but I havent found any way to do it in windows. I found some tutorials how to apply microcode via BIOS modification method but it worked only on legacy BIOSes.

Hi. Is the latest mod for 3.05 with unlocked EC? Any possibility to control fans? I am currently using IdeaFan app but its annoying. I have allready flashed modded nvidia bios for ultrabay gpu for 3.05 bios but little tweaks to fans will help.

Hi guys I just want to ask if there is any advantage of downgrading from 2.07 to 1.10 . I have Lenovo y510p 755m dual graphics. It came shipped with 3.05 but I downgrade it because of whitelist to 2.07. I dont know if you have noticed that when you use v2.07 instead of 3.05 graphics get hotter while playing. Maybe its just me. Any news on mod for 3.07 or its just better to wait for lenovo to publish their own official bios with whitelist removed? Sent from my GT-I9505 using Tapatalk
