  1. Hi, Means original cable got burn marks on it, turned brown and due to heat, insulation became hard and started to crack. Before there was any short circuit, i bought one from ebay. Sorry, i don't have pictures currently, but you can imagine, i think.
  2. Spacer mod on ultrabay is extremely dangerous,because the pcb is so small and weak, it will bend. Not saying it will crack, but eventually will, but traces inside can be broken via bending. There is 3 solution with ultrabay, undervolting, mine can do 1124 with 1V, or do the fan mod, which is tricky, and it will make it louder. ( combining these two is funny, 6x temps and acceptable loudness, pitch is higher) Not unbearable, but loud. It will be an abomination, but it will work :)with that, around 1300mhz gpu speed is doable. ( To be able use that speed, maybe you should mod internal psu cable as well) Or make the fan work @ 100% always by detaching rpm signal from board. Check the beginning of this thread for some hardware mods.
  3. Try 72Hz which is a standard refresh rate, and it will downclock. ( Hopefully) 90 will be ok for 30Hz videos, youtube, some ntsc dvd,( actually 29.97 fps) , but 24Hz is more common in video formats, bluray, dvd even. To be exact it is 23.976. So use 72 or 71.928 for those.
  4. Sorry to hear that. Never tried it out, hopefully never have to... Possible B plan ,if this flash write thing is true, is do desolder bios chip, and externally program a new bios with default settings to it.
  5. this is not standard boot, it is recovery. Try it!
  6. As i know, some bioses write back settings to flash. Open bios with tool, check for recovery file name, put it on pendrive, fn+esc, or fn+B start and pray...
  7. @Jerenny, Valley, not Heaven.... What benchmark is not boring for you? Furmark? And yes, it takes time, beacuse if you want co compare coolings, they have to reach working temperature. After that, you have to eliminate heatup readings, you have to reset hwinfo so all the readings are done during load. And yes, even the screenshot have to be taken during that time. And you have to sroll down to show gpu readings, cpu is irrelevant in this case. ( almost... ) Notice, there is 3C fluctuation, so thermal load is almost constant, no idle readings to alter average and minimum. Let me give you an example: It was taken with 26-28C ambient, CPU is down to 2 cores with HT, max 3.1GHz, to match i5. Laptop is slightly elevated, no external cooling, since we want to compare effectiveness of raised fan speed. So the upper case is with default fan speeds There is another 6C is shaved, so if you are near boiling temp, increasing fan speed can help you. Note, this is still without external cooling. But: Why do you need to shave more degrees, if you are very far from the maximum? Ok, you can say enthusiasm, i can accept it. Maybe, strong maybe, i could accept the elevated noise because of high rpm, but hey, this is a laptop, won't be that silent as a watercooled desktop. But in current state, this pulsating noise is a killer. So if you can do the same as above, extending it with 2 other cases, when laptop cooler is on, we could get a better picture, what can one expect from a cooler, this mod, this mod with a cooler, etc.. To bulk answer all the remaings post since that: Using high msaa can lead to lower GPU usage, because performance will be narrowed by membus width, and gpu will be bored. @1V 1124/1350 is stable with 2-3 degrees higher, still under 80. ASIC is 84/76, so there are similar quality chip like 650m, but it is silicon lottery, some gets better ones. @1.2V with low ambient i was able to benchmark @ 1.3Ghz, but not usable for 24/7, not just cooling, PSU was about to explode too. Edit: About cooling mods: With that you are able to squish thermal pads a bit more, so heatsink is touching and/or pushed to gpu better. Modifying ultrabay fan is a tricky one, a wouldn't recommend that, only if you want to reach 1.2Ghz or higher. Don't wait for a video tutorial, read that through a few more times, and it will be clear. If don't, feel free to ask.
  8. Can you please run Unigine Valley, windowed, near 1080p? MSAA not required, but let it heat up first with 3-5 rounds, then reset hwinfo, and then run 3 more. This way we can have a reading of average and usage based fluctuation of temps. Thx. ( At default speed, you can go lower with voltage, mine is ok @0.95V. @1V 1124mhz looks stable. Flashed into ultrabay, and merged into main bios, so no nvinspector needed ) Edit:: And if everything else fails, do some hardware tricks like this: http://forum.techinferno.com/lenovo-ibm/4921-y500-y510p-spring-mod-spacer-guide.html
  9. Monitor cpu speed with xtu, use gpuz for gpu monitoring, there you can see perfcap reason.
  10. Because that community has people with more knowledge of EC modding. Asked Svet from MSI, if he is willing to do EC modding for us, because his vbios editor is supporting EC modding of MSI bioses recently: " Quote or stricly MSI machines are supported by You? Yes, EC modding is limited to MSI notebooks only [supported models are listed in 1st topic] " It worth a question, but from his point of view, it is completely understandable. We have to find our people, with proper knowledge.
  11. Jerenny, no one wants to start a war.... BD PROCHOT is the default method of throttling, implemented by intel. But since Lenovo used a more direct approach, we cannot go around it, with deafult methods, like prochot disabling. Luckily we have TS. So far, by my experience, the methodology of EC is the following: - You start to stress CPU. - Because it is on a common heatsink with GPU, GPU starts to heat up too. - When GPU is reaching 65C, EC sends a command, setting CPU speed to 2.4. - When GPU is cooling down below 58 ( or some duration under 60, cant test it for sure) EC is setting max multi again. When you are using TS, you are setting a direct multi, which overrides EC setting of multi 24. Tested it, during EC throttling, using TS, setting max multi, and turning it off doesn't going back to 2.4 so EC is only setting command once/heatup. When it is cooled down below 58 and then heating up again, EC throttling occures again @65C. Second GPUZ is used to run render test, beacuse by default GPU is only heated up to 62C, (staying flat on desk ) so I had to push gpu to heat up a little to start EC throttling. Secondly, even using unlocked bios, configuring thermal trip points and so on, fan speed cannot be tweaked, since all is controlled by EC firmware. Hope that clears up things a bit.
  12. By stock you mean stock boost, but with enhanced TDP and offsets? From my point of view, it is more than welcome! Thank You! Or if you can give me some hints via pm regarding vbios change, maybe I can do it myself. Tried it already once (extracting bios, editing vbios, repacking), but no luck, had to remove ultrabay, to be able to boot, and revert bios.
  13. No, AVX can not be turned off via bios, even with unlocked one. HT is only good when running more than 4 independent threads( fe. encoding) , or if application is optimized to use it.BF4 can benefit from it, Crysis3 maybe. Look for reviews, probably there are a lot regarding HT and those applications. There are no options in unlocked bios, regarding this. This is configured in EC ( embedded controller). Run cpu test, monitor cpu speed, and gpu speed .
  14. With modded bios TDP limits can be set, but it is saying, higher than default will not be set. But, according to XTU it is. You can set it further with XTU, when MSR is not locked. Current limit can be set via unlocked bios, with hint saying higher than fused will not be set, and in this case it is saying right, current limit is staying @default. With non AVX prime95 you can run it with undervolt staying under the default TDP, 43W with HT disabled and -100mV. AVX is different story, with that you can run into current limit, and speed will be 3.0Ghz, regardless of way higher TDP settings. And default Lenovo throttling is based on GPU temp, if any GPU is reaching 65C CPU is down to 2.4. But it is done via direct multi set by EC, not standard methods like BDPROCHOT. ( latter can be disabled in unlocked bios, but since throttling isn't based on that, it does nothing)
  15. First of all, thank you @svl7 for your dedicated work. Doing it is simple, maybe 1 step should be added to 1st post, before downgrading, set bios option to be able to downgrade. ( For some people it is trivial, i know, but for those who it isn't. ) Regarding VGA bioses: I can consider myself lucky, 1st card can do 1200@ 1.07V, 2nd(ultrabay) @1.09V with original bios. 1.1V is too much for me, but i have to point out, i'm a minority here, most of the gpus use more than 1.1V by default. Yes I know, i can use negative offset with nvinspector, but I used that just for benchmarking with overvoltage. The reason it is in past tense, because it tends to mess up the auto downclocking on lower usage. By default when usage is lower, and GPU is donwclocking, it is downvolting too, so i can end up for example 1.1Ghz with lower than 1V. Why is it important? Because it allows GPUs to cool down. Now with this bios, GPU 3D voltage is locked down @1.1V, and even with auto lowered 3D clocks it stays the same. It can be good, because it allows a simpler/ more stabilized overclock, you just have to test 1 voltage and clock combo. With default bios it is more complicated, because you can have a stable max clock at certain voltages, but when it downclock/downvolts automatically, it crashes. But when we are using the cooling on the edge, every bit counts. Can we have a version where auto downclock/downvolt is working? Thanks in advance!
  16. Well, p95 wasn't reaching current limit, maybe that was without undervolt, or remembered something else. This is with -100mV. Temps a bit high, maybe i need a repaste or at least dusting the heatsink. Until its done, linx test will be skipped @Tech Inferno Fan: doesn't seems to be that bad, mine does +200mhz, igpu is turned on, (using optimus atm) maybe that is why I have hotter cores, and almost 1W lower TDP comapred to octiceps's Ivy
  17. With unlocked bios you can raise TDP limit, and time window more than that, but even with that, you are not able to modify current limit. Unlocked TDP allows to run [email protected], limiting it by current, but this is with modified cooling, with stock, it will probably fail. Anything else, not linx of course , doesn't push cpu that far, so default TDP in real world situation is enough.
  18. Only way is trough EC, since every temp and fan related settings in unlocked bios does nothing at all. Fan is not controlled via bios and ME.
  19. @octiceps: Yes, that is correct. And EC is forcing multi directly, going around the standard of PROCHOT, which by the way can be disabled via unlocked bios, so reverse engineering of EC would be good. Or using TS of course. @hooman008: 2.6 with TS is probably because of temp or more likely TDP or current limit reached. ( with unlocked TDP AVX test is dropping from 3.4 to 3.0 because of current limit)
  20. Actually, they do get hot. I don't understand, why you say, baseplate isn't doing much. But please, explain then, what is the purpose of the baseplate? (Which is not alu, it is some kind of alloy.) Cpu backplate is hard enough, baseplate will do almost all the flexing due to strain. Ok, then don't do it This mod is not for the faint hearted. (Actually pressure in this case is not problematic, since baseplate can flex. However uneven pressure on the chip, mostly during assembly, can be, and you can corner the chip. But cpu baseplate flexing can introduce 3 type of issues: - Cpu fan housing is connected to cpu plate, with flex it is moving too, it will not be level with motherboard and it can push keyboard up. - With too much flex it could reach SMDs next to haswell ic, and cause shorting. - When it is reaching side of the cpu, increaing pressure on it, the center of it will come up, decreasing the pressure on the ic, even lifting it up from it. )
  21. They will heat up each other eventually, since both heatpipe is soldered to common fins. Those are great temps, but good luck with the mod, if you are doing it, and any feedback is welcome. Main pcb did not flexed, but the heatsink did. When used too much spacer with cpu, the fan housing bended so much, it pushed the keyboard up... Be extra careful.. Ultrabay PCB is weaker, smaller, no backplate, don't wreck it. Don't do it. If the unit is new, test it first, if it has any flaws. Don't loose warranty, without being sure there are no issues, other than high temps. Ultrabay can be opened, because there is no sticker on it. Yes, VRAM chips, GPU VRM, CPU VRM coils.
  22. First of all, mesh is the original Did a picture from the other side, where you can easily spot where cutting was involved. I wouldn't rush things that much if i were you. Try it with removed bottom plate, to see, if there is an improvement. Then try the spacer mod, with and without bottom cover. If coverless seems good, then try the intake mod. If you achieved that much of temp drop, with your games/apps you are using, what is satisfying, no throttle, around 80-85 max with oc, stop. The fan mod is irreversible, fan controller mod is better in that point of view, and if you managed heat with those mods, no need to do it further. However, if you want to, need to.... You can see where inner chassis element was cut, in order to get way more fresh air into the laptop. You can extend heatsink with some copper pieces, i think with external cooler it can be even better, since you can blow air onto gpu heatsink directly, and more into chassis. ( I'm not using any...) Why block it, if almost the whole bottom plate is mesh. Come on Lenovo, really? And the ultrabay... The mod stucked at wip status, so other side and inner pictures will not be published, since i think they belong to ghetto modding... The right side fan is the one i broke during first assembly, so i had to reorder. But it is good for measurements and comparison. You can see the fitted fan, compare the original fan to the new one. it is bigger, thicker. The new fans diameter is almost the size of the original one's metal plate. Please excuse me the quality of the cutting of the chassis, i was in a hurry, eager to see results, and since then i had no time to correct it. Top cover of inner fan housing had to be removed, due to thickness. And between new fans baseplate and inner housing i had to insert around 1mm of spacer, thickness... ( Between the baseplate and rotor, in order to lift up the fan, not to touch chassis. ) I strongly suggest, try other mods first, even combine them, leave fan switch as last resort. (There were lot of discussion about undervolting via Throttlestop or XTU. Overclocking can be done via unlocked bios or Throttlestop)
  23. Try it for yourself We wrote down our results, but i can give you a little update. It is as good as it was written down. But if you want to overclock your cpu and gpu, it can be modded further. I also did a chassis cut mod, where i removed dust filter, the inner bottom chassis element was also cut, sou you are able to see gpu heatsink. Gpu heatsink was tweaked with additional little copper heatsinks glued to the gpu plate. Chassis was cut where ultrabay is intaking fresh air, like seen on the following picture: But most of these were for cpu and internal gpu. With all these mods i was able to run the cpu undervolted with 100mV, and overclocked to 3,6 1C; 3,5 2C ; 3.4 3C; 3.4 4C Ghz, gpu is running at 1200Mhz, memory is at 1350 with reasonable temps. around 85 Ultrabay is a different story.. i was able to drop ultrabay temps, when load was below 80-90%, with not so long peaks to 99%. But when load was constatly above 90% ultrabay got hotter and hotter by time, with the mod it was slower, but still climbed up to 97C and throttling... So ultrabay is a f***ed up design, becasue of lack of air movement through the heatsink. ( not mentioning upper faults which were fixed by my mods. ) There are two things you can do, if you have the will, courage and knowledge. Do a hardware fan speed increase mod as Bagyusz did excellently, a fellow mate from my local forum @prohardver.hu. Lenovo IdeaPad Y széria (Y40, Y50, Y400, Y500, Y410p, Y510p) - PROHARDVER! Hozzászólások Or, insert an Y500 fan, Genuine New Laptop CPU Fan for Lenovo IdeaPad Y400 Y500 See Pictures | eBay Which by the way was a PITA, better prepare your dremmel, major cutting was necessary. But the results were spectacular. With Serious sam3, where after 10 minutes playing ultrabay was started to throttling, check those temps: Lenovo IdeaPad Y széria (Y40, Y50, Y400, Y500, Y410p, Y510p) - PROHARDVER! Hozzászólások And it was done by standing still at a scene, where both gpus were loaded CONSTANTLY @99%. So yeah, Lenovo f***ked it up badly, but as seen, an EC firmware mod, where ultrabay fan speed is increased, those temps can be kept managable low, without throttling. Shame on you Lenovo, beacuse those ultrabay design flaws could be eliminated by a simple firmware, but you are unable, or not wiilling to do it, despite the large amount of complaints. And all of these test were done on a Logitech AltoX notebook stand, with no additional fan involved. Have a good mod!
  24. Dear svl7! Bios used for internal nvidia is based on the presence of ultrabay. If ultrabay card is removed, different bios is loaded for internal vga. Your vga unlock is only affecting the the bios used with sli, when ultrabay is removed, internal nvidia is locked again. There are 2 different nvidia bios in packed in system bios: So if it is possible, please mod all the bios, and if vga voltage mod will not be universal, please don't forget 750m owners. ( As of lowered 3D voltage, is it possible, to set it via parameter? ) Thanks and regards Adam
  25. Did a quick tryout, and no success. Disconnected RPM pin does nothing, and this is no surprise, because my previous notebook, which was an MSI GT7725 acted like this too. In that there was a 3 pin fan, so this is unrelated to PWM. However i did that mod years ago on my old Acer Travelmate 5720G, "game mode" switch was working with that one. The MSI had a little 3rd party utility, which was written for gx740, where i was able to overwrite fan lookup table, but was working, since they had the same EC, despite generation differences. With this lenovo i think its a bit more complicated, because there is 2 fan, and i bet, ultrabay has an individual lookup table. edit:Official MSI GX640 Owner's Thread - Page 113 found it, it was written by Pherein@notebookreview While we are there, probably we could find the register of EC which is responsible for 65C gpu throttling issue, since even with disabled BiDirectional PROCHOT ( Intel ME interface for software disable turbo) EC is still throtthling the CPU, so it is wired deep
