  1. 340.52 is out. I heard that with it you cannot change voltage.. Have anyone tried it yet? http://us.download.nvidia.com/Windows/340.52/340.52-win8-win7-notebook-release-notes.pdf
  2. The only thing I can think off to try - reset to factory defaults, save, reboot, select UEFI, disable secure boot, reboot, and then select legacy mode, boot from usb, reboot. Maybe secure boot somehow gets in a way or default settings..
  3. Why oh why it is easier to access EC on Alienware laptops and control the fans, but not on the lenovo ones >.<
  4. I have seen that 4700mq has microcode update 0x16 as opposed to our original 0x12. See XTU Hardware here Woomack`s XTU score: 818 marks with a Core i7 4700MQ or here rho `s XTU score: 860 marks with a Core i7 4700MQ Here is even 0x17 http://hwbot.org/submission/2542205_carbide_xtu_core_i7_4700mq_848_marks/ A lot on the TOP10 are with either 0x17 or older 0x8/0x9 microcode updates. They supposedly changes C0 states, power management, etc. Questions are: 1. Is microcode in BIOS or in CPU Firmware ? 2. How can we upgrade it? AFAIK, microcode can be downloaded from intel website in tar.gz format. And somehow could be used in linux. Thats the only info I have.
  5. @techmaster, I remember reading that 4930MX or 4910MQ is with the same socket but produces less heat, thus is less watt hungry. What do you think? See Intel Core i7 4910MQ vs 4700MQ performance per watt is almost twice..
  6. I think its good not to have a bracket - it holds quite well in place and is hot swappable - so I can remove the caddy and put it back without windows restart.
  7. I have made a walkthrough through the modded BIOS because I tend to forget all the names etc. And it is easier to give a link to some second of a video than getting my camera to take photos all the time.. Here it is : . Feel free to use.
  8. p95 28.5 I have noticed it is true, still need TS. I tried both on/off short power limit, setting long limit to 110W/350W/etc, but there are two things: depending on the test I am running, I usually run either into thermal throttling (i.e. usually when P95 is running) OR into Core Current Limit TDP (i.e. when I run XTU benchmark with multiplier set to 2.9T). Current limit is set to 85 A and shows as locked in TS (btw I tried to lock it in my intel 2600 and after being locked the checkbox got disabled permanently). I have tried setting BIOS setting to max 8189 value or something like that, but it did not change. Answering your question about watts.. TS shows 40-45W, more like 40W, voltage shows as 0.910V, 0.990V, etc. And I run everything with -70/-100 mV undervoltage. I think original pasting job was terrible, but I am yet to conclude and open up the laptop..
  9. slv7, I think ultrabay vbios is working for both of GPU in SLI mode.. I think of this because when I was changing vbios separately, when in SLI ultrabay VBIOS took presedence and allowed me to use modifications which I have done on ultrabay. Now I am wondering if that is really the case or I just missed something.. I am probably wrong? What is your preferred method of putting a stable strain on GPU to test how its working ? - - - Updated - - - slv7, do you think it is possible to both leave auto downclock/downvolt behaviour, usual 1,106V , but also unclock min/max on base clock and voltage?
  10. Oh, you may be right. Also AVX, too, can be disabled in uncloked BIOS(Update: AVX CANNOT be disabled!). Do you think HT disabling is good i.e. for games, like BF4 and Crysis ? I have seen reports where they state FPS with HT disabled can be worse, and multitasking is not as fluent in windows. Regarding the GPU-CPU relationship.. I personally did not notice that behaviour. Maybe I have something else changed in unlocked BIOS regarding that, not sure yet. Ill will run some tests again to see and double check BIOS settings.
  11. You can put GPU to 99% load either with FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net (press P on keyboard in order to enable HUGE strain on GPU) or MSI Kombustor - Burn-in test and benchmarking utility - Scores page Another thing - block air vents with simple paper/book cover in order to test how it acts on huge temperature (be careful with this please..).
  12. Not sure how to test it properly, but before clocks would always drop to 2.4 Ghz. Now, I can maintain 2.6 Ghz when full loaded with Prime 95 (i think I run heat related torture test). If you set multiplier in throttlestop to 2.6 Ghz on unmodded BIOS does it throttle back to 2.4 Ghz on TDP/Thermal? What temperature does it maintain then ?
  13. Lets assume you are using default layouts for all programs. Open them up: See CPU Throttling percent in XTU and TDP Throttle in ThrottleStop. If either of them is on - CPU is throttling (either on TDP aka watts or in XTU aka because of temperature). BD PROCHOT option sends signal to throttle because of temperature. Interesting enough would be to see whats happening on your end. P.S. Do not mix ThrottleStop and XTU running at the same time - it can produce different results as each one overrides another.
  14. I have just recieved this y510p hdd caddy: 2nd HDD SSD Hard Drive Caddy for Lenovo IdeaPad Y500 Y500N Y510P | eBay It came together with a bezel. And it i HOT Swappable - if I boot into Windows 8.1 with it, I can remove it, replace hard drive and insert it into the ultrabay slot again.. Here are some photos of the bezel they provide together with hdd caddy: For a price of 16 dollars, its super nice! I inserted into it original 1 TB hdd which came with y510p (I use ssd inside computer mSata) and I get 100 MB/s speed even.
  15. First CPU. Could you please download HWInfo64 and check there for CPU cores Ghz? It will show which cores are at which frequency, might be better to understand what is happening exactly. Are you using Intel XTU - extreme tuning utility? It could also show you some more info. Then again, I recommend downloading ThrottleStop which will show yet more information. Having at least screenshots from all those programs we could analyse and decide why "clock fluctuating between 2995 and 3095 GHz over and over". For now, I can just be guessing the real situation why's that happening, and there are a lot of variants why. Regarding the LCD.. Are you using SLI configuration or single GPU?
  16. In unlocked BIOS thermal configuration you can set manual config - it shows that CPU throttles because of temperature at 95 C. Meaning if your CPU throttles at 65, it could be TDP based throttling (ThrottleStop shows when that is happening). Go through Advanced options and search for Short/Long power options. You can set TDP watts in BIOS but also enable unclocking them to be used further in the system in Intel XTU for example or ThrottleStop (please use 7.00 beta 2 version). What I did to disable TDP is disabled short power in XTU, and set long power to 300w or so. Now, what I am left with is temperature based throttling (but not TDP throttling) at 95 C (I have not changed that yet). So now basically I can load 100% all cores when I set 2.6Ghz (when running p95) on non-modified stock cooling / non-repasted. Setting 2.7Ghz and temperatures too high.. Or I could set 2.8-3.2 Ghz for XTU benchmark or some games and still get no temperature throttling, because cores are not loaded 100% all the time. And I do all this -63 mV undervolted. What I like is that Ghz are not spiking during CPU load, meaning no random lag in games mostly, which leads to more stable FPS in games. I cannot say that these are the best settings, maybe someone will share some other settings ?
  17. please do not forget that modded bios removes whitelist as well lets you make num lock turned on by default, controlling thermal points, etc. AND you can always get back to original 3.05 pretty fast with no consequences. That being said, I can run heat p95 test w/o tdp and w/o thermal throttling only on multiplier set to 26T with throttle stop. If I do XTU testing or during gaming, I might go up higher to 28-32. But yeah, w/o repasting and some hardware modding cannot use full potential of 36T. And let us not forget that our power brick is only 170W.. Meaning if we only use CPU, we might get somewhere, but using 2xSLI, adding some JBL sound, playing CPU intensive game.. and pretty much even with wonderful cooling and undervolting done we can almost certainly run into that 170W. Am I not right?
  18. I use cooler master u3. I like to use it without fans for daily use - as its all metal with round holes it really helps with passive air circulation, also I use it to carry the laptop through the meetings. Then when I am putting some medium stress on computer, I just put the 3 fans under cpu, gpu, etc, and turn them on - laptops is cold then on outside. And when I am putting heavy stress on the laptop, I remove also bottom cover, etc.
  19. So you are all good. Because internal VBIOS is inside BIOS bin file.. so IF you flashed to 3.05 modded, you also got VBIOS modded for internal GPU. And you flashed ultrabay GPU, so external one is flashed too. All good then? - - - Updated - - - For me 5.128.x did not work - got error, at least for 755m. But 5.136 worked.
  20. slv7 asked for some voltage testing.. but I just did not have time to actually test until it was too late and slv7 released the mod. So here are mixed results before the flasing (and noted difference after the flash in parenthesis). 1 x 755m [built in Nvidia vBIOS: 80.07.A8.00.2E] AC desc, voltage, Base/Mem intel HD, 0.806 V, 135/202.5 Mhz idle, 1.031 V, 979.8/1350 Mhz 99 load, 1.106 V, 1097.4/1350 Mhz Battery intel HD, 0.806 V, 135/202.5 Mhz idle, 0.850 V, 135/400 Mhz 99 load, 0.850 V, 135/400 Mhz Note: Seems that Nvidia Power management works on battery mode Note 2: it does not let me to overclock before the 755mOC - nvidia inspector just returns to default values. 2 x 755m in SLI [ultrabay Nvidia vBIOS: 80.07.A8.00.32] AC desc, voltage, Base/Mem idle, 1.025 V, 979.80/1350 Mhz (1.1000 V on OC rom, 1097.4/1350 Mhz on OC ROM) 99 load, 1.106 V, 1097.4/1350 Mhz auto -12.5 mV when OC +135 base/200 mem (1.1000 V on OC rom; DOES NOT lower voltage when OC +135 base/200 mem, but can do it yourself) Battery idle, 0.806 V, 135/202.5 Mhz 99 load, 0.806 V, 135/202.5 Mhz Note: seems that 2x Nvidia GPUs are undervolted more than on 1x Note 2: seems that original 755m VBIOS, when I set +135base/+200mem settings, lowers my voltage with -12.5 mV Note 3: seems on 2x SLI, vBIOS on Ultrabay works for both GPUs Note 4: when using 755mOC slv7 rom, +135/+200 always crashes Unigine 4.0 benchmark and reverts to 0/0, but when using stock it does not. BUT, I tried +120 base/+200mem, -12.5V, and I got better results than with +135base before. So all in all, I get better results with 755mOC rom than with original. Its just that original ROM lets me make +135base/+200mem max and manages voltage automatically. And does not crash on those settings. Then again, it has 1.106V under load while slv7 755mOC has 1.100V. I guess it makes a difference on my card. My friend has exact same y510p, but it crashes unigine benchmark at +135/+200 on original VBIOS while on my y510p it does not. I guess that 0.006 V (or 6 mV difference) does really matter on my PC. Also, even with 755mOC rom and modded 3.05 VBIOS I cannot change temperature prioritization in nvidia inspector. If anyone knows how to change that setting please tell, I could not find anything in the BIOS for that.
  21. I would also like to share. First of all, I extracted Yx01.bi? BIOS recovery and wanted to make sure I can recover from unexpected. But nothing worked on y510p, tried FAT/FAT32, different block sizes, bootable and non-bootable flash, tried different usb ports, tried different key combinations (fn/win+b/c/x/z/r/Esc/Space). Nothing worked. A the hell with it.. Maybe anybody knows how to fix bricked y510p if its not booting and with black screen? Next step - I have done a lot of benchmarks on my y510p to make sure what, how, and when works, both with 1x755m and 2x755m SLI. I have also tried modifying my vbios with kepler bios tool. Apperently, I have done the same modifications as lsv7 did and had some.. issues. Slv7 is right - lenovo engineers did something strange with those vbios'es. I will share some tests about vbios on the next post. So, before actual bios update, I made my bios copy with several tools - every single one producing binary equal images. Good. I used andys tool again, extracted vbios from bios. Also used nvflash for windows and backed up nvidia bios. It produced same image as from DOS. Better save than sorry. I ran BiosFixer of 3.05 mod on my extraced 3.05 bios and got myself my modded bios rom/bin. Then I downloaded Rufus, made FAT32 FreeDOS bootable partition with 2KB allocation units. Put there EC.bat, BIOS.bat, 3.05 original bios with restore.bat (that I could restore if something happened) and made VBIOS.bat to flash. So, I rebooted into bios, restored factory default settings, disabled secure boot, enabled boot from usb, enabled flashback support (all those options which could prevent flashing bios to 2.07). Then, booted into Windows, ran 2.07 stock (Ran as Administrator), windows restarted into DOS and flashed my bios. So far so good - EC and BIOS 2.07. I went straight into BIOS and restored factory defaults again (thats what you do before and after bios flashing). So, again, I rebooted into bios, turned on legacy bios support, restored factory default settings, disabled secure boot, enabled boot from usb, enabled flashback support, restarted. This time into the bootable USB. I ran BIOS.bat, flashed into 3.05. I ran EC.bat and got error - I was only on AC, battery taken out. Then I put in the battery, and only then flashed into 3.05 EC (remember, was 2.07 after last flashing). Then, I tried VBIOS.bat and.. it failed. Tried making backup of vbios - was success. But flasing failed. No biggie - I figured I had bad nvflash for DOS. So, I turned off computer, put USB into my other laptop and checked the version, it was 5.128.x. So, I downloaded 5.136, put into USB, inserted USB into y510p, booted into DOS, flashed VBIOS and.. it was success this time. Well, last time I did VBIOS flash on my own modified VBIOS, I did with nvflash for windows, just I needed to restart computer after that.. but it was same as from DOS. I rebooted into BIOS again.. 3.05 BIOS, 3.05 EC, all good. Restored factory default settings! Booted into windows 8.1. Seems slv7 is right - everything is working just fine. I also can unlock and modify TDP of 4700MQ at last - I can get rid of TDP throttling and get to temperature throttling only at last. Also, main fan speed and temperatures can be modified, changed from default 55C for TP1 (low->med fan 75%), 71C for TP2 (med-high 100% <- it is not over 100% as in dust removal function, just normal 100%), and on 95C passive throttling on. And.. ran some tests on VBIOS 2x755m SLI again. Results will follow..
  22. Not entirely true - if you have windows 8.1 you might encouner some changed behaviour.
  23. Yes 2nd HDD SSD Hard Drive Caddy FOR Lenovo Ideapad Y400N Y410N Y410P With Bezel | eBay looks like the original when I recieved it. I am yet to recieve the y510p one.. Still in transit that one. Update: here you can see some photos of y510p bezel and hdd caddy: http://forum.techinferno.com/lenovo-ibm/5265-lenovo-y510p-ultrabay-hdd-caddy-3.html#post100480
  24. what Id like to know what you get on unigine heaven benchmark 4.0 on ultra 1080p 8xAA and v-sync..
