  1. Hello All. I have a question: I need to repaste my laptop. To clean the old thermal paste, i went to the pharmacy and bought an acohol solution with 78% alcoohol (highest content they had). However, the same solution is also 2% salicilic acid. There are no other components in the solution (except 20% water). Can i usr it to clean the CPU anyway? Thanks!
  2. Hey guys, I recently upgraded my M15x with a i7 920XM and a GTX 780M. Flashed the modified vbios, got a 330W brick, pulled the pin, installed newest drivers and did some gaming. Everything worked pretty well, only sometimes the 780M reached 93C and clocked down, but still ran stable, never crashed. Therefore I decided to get a finer TIM and repaste. Bought the Noctua NT-H1, carefully repasted and voila, temps dropped around 15C. But here comes the catch: when trying Furmark or some very intensive game, the GPU reaches 88C and screen immediately turns a random color. No downclocking, no limiting, just a sudden crash. Only thing I can do is a hard reset. This doesnt happen on any other occasion, can game on 80C for an hour. Do you guys have any sort of idea why the laptop crashes at 88C, while before it worked at 90+ without a problem? Things I tried: Used DDU and reinstalled the drivers, also tried older version. CMOS reset. Cleaned everything, no dust left anywhere. Carefully checked the GPU for any visible damage or old TIM residue. Tried undervolting and underclocking, only took longer to get to 88C and still crashed. For the sake of it I actually strapped a Corsair H45 AIO to the GPU heatsink. Now i get to max 55C with furmark, but the laptop still cashes after around 2 minutes. I would be happy for any suggestion, thanks!
  3. Thermal Paste Complete: Mandatory. Not an Option. * Don't mind the MX4 LOL that was just left over from something... How about that toothpaste that is rated at 401w/mk...which happens to be the thermal conductivity of copper. Greetings, I will be repasting the P775DM3 very soon and will be posting up the results w/ a lot of pictures for your entertainment. My liquid metal paste of choice will be Grizzly Conductonaut, however, I'll be experimenting with other pastes as well to satisfy any curiosity as to if one can get by with just traditional paste. (Highly doubtful, but I am curious about GC.) Traditional paste wise, I have a feeling that GELid will hold up pretty well. While I'm at it, I'll also be replacing the thermal pads. Depending on how warped the heat sink is, I have pressure paper handy to be able to test the contacts of the die and IHS against the Heat Sink. If needed, I have copper shims standing by of varies sizes from 0.1mm to 0.3mm+ ... Below are the conductivity numbers for the top Liquid Metals and Traditional Paste: (As we know the numbers don't mean everything, however, from all my tests done so far, Grizzly Conductonaut has always topped CLLU by an average of ~3C. Results may vary and it can be the case where it's the other way around. However, the thing here is that with these beasts, every drop in C's count. It could make all the difference.) Liquid Metals: Thermal Grizzly Conductonaut - 73 W/mk Coollaboratory Liquid Ultra - 38.4 W/mk Coollaboratory Liquid Pro - 32.6 W/mk Traditional Paste: Gelid GC Extreme: 8.5 W/mk Grizzly Kyronaut: 12.5 W/mk ICD: 4.5 W/mk ------------------------------------------------------------------------------------------------------------------ Project 775 Journal: Straight out of the Box: The temps when running OCCT on the CPU reached 99C on all four cores. Even on F1, the CPU temps all maxed out. Yikes right? As for the GPU, when running Unigine Heaven and Fire Strike the Temps were also in the high 80's and 90's. Repasting is a must IMO. 90C's is not okay and there's no justifying that. I know it's such a shame on Clevo's part for poor QC and lack of engineering (as demonstrated by the crap ADDA fans that are used), but it is what it is. If you want something to just work out of the box without any modding, then a DTR is not for you. Simple as that. Yes, it should work within normal operating temps right out of the box, of course, we would all agree. A DTR is for enthusiasts and those who have the willingness to get under the hood. Some of us thrive on this fact, while others don't, but at the same time this doesn't give Clevo an excuse to go cheap on us. Project Delid + Liquid Metal Magic: (9/22/16) The Repaste and Delid are now complete. I've been gathering temp data non stop, along with fine tuning the machine to find where it is the happiest. The temps have been amazing and I'll be posting up a full review shortly. - Stay tuned... Fine Tuning: (9/25/16) It's been a blast fine tuning the beast and I think I've got it to near optimal range. The CPU is a winner in the silicon lottery, thank goodness. I'm holding 4.6GHz @ -200mv Core / -200mv Cache and it's very stable with gaming, running benches, video encoding etc...As for the GPU, it's a working progress. After about 100+ runs...yes really of fine tuning and recording data on a spreadsheet, I think I've found the GPU's sweet spot. It's not a massive overclocker chip, but it's good enough to get a great boost out of it. Then again, my expectations are very high so anything sub par is not good enough. I'll be running more benches tonight and hopefully the tuning will pay off to take the #1 spot int he P775DM3 Class for Fire Strike, Unigine Heaven, Cinebench R15, Time Spy, wPrime (already recorded and sitting at #1 in this class) etc... I'll keep you all posted! ------------------------------------------------------------------------------------------------------------------ Please post your results using the format below in order to keep things uniform and organized: >>> Before repasting, please run the benches and record your temps for a base. <<< >>> Please BOLD the answers as show below. <<< Application List: (Click below to Download.) 1.

  4. Hi! edit: merged with Conscriptvirus's post so it's easier to follow: This modification is very dangerous, can lead to broken chips. Don't say i didn't warned you... edit: he's right, it is easy Lenovo did a sloppy job with cooler, too much thermal paste, weak springs, overheating and throttling machines... First of all, disassemble the machine. Then do a repaste, with bare minimum amount of thermal paste, and remove cooler again, check thermal paste spread. Remove screws from cooler, by removing little plastik washers, keeping the screws to fall out. My gpu heatsink was not paralllel to motherboard, so the corner without screw was slightly bended upwards. Twist the gpu heatsink, so that corner is pushing gap pad a little bit harder. Be very gentle, you dont want to broke your heatsink. You can check level by putting your heatsink on flat surface with gpu screws removed, cpu screws stays in place for now. Then place a 0,5mm spacer under the spring like seen on the following pictures These are screw number 4 and 5. Screw number 6 is using a weak spring, so use double spacer, or change it to a stronger spring: Put back plastik spacer, so screw stay in place. Do the same process with cpu heatsink. You can do this to ultrabay as well, but take extra caution, since there is no backplate, and it can lead to warped/broken board. Lastly change the gap pad over cpu vrm area, because it is too tick, I used 0,5mm piece: Aaand it's done! Put back heatsink, use as little amount of thermal paste as possible, and enjoy 10-15+ lower temperatures. Spacers was lying around, i had the spring from some old heatsink, so dont have exact types and diameters, but Conscriptvirus did the mod also, his mod is better to look at, spacer perfectly fit into heatsink holes edit: I also did cpu mod, ended up adding a washer to screw 6, despite of changed spring, gained 1C-3C. I can run XTU stress test under 85C with -95mV and 3,4Ghz 4core. GPU and CPU idle is under 50, without notebook stand with fans. Thanks to Conscriptvirus for his effort and pictures. If it worth to be sticky, Mods, please make it one. Regards

    m14xR1 GPU Hitting 99c

    Hello I have a m14xr1 555m which has been repaired by dell 4 months ago. Despite a terrible service from the technician and two MOBO replacements, everything was working fine until few weeks ago when I was playing diablo3. FPS dropped to 5 and the game since then has been unplayable. I noticed my GPU temp was too HI reaching 99c causing GPU throttling. I have been reading a lot about same issues from several people with the same machine claiming different causes: (Nvidia drivers, GPU physics load, Virtual Sync config, Blizzard patches, processor cores load, Dust in fan, etc). I have tested all suggested solutions and even re-pasted with IC diamond 24. After all this it seems that the FPS drops and thermal increase vary from machine to machine for Daiblo3, so I decided to test with any other game and discovered the thermal increasing was happening again. Before calling Dell again I would like to know if somebody knows what is the cause for those thermal increases in such way as idle remains between 50 to 60c. I acknowledge the GPU rise in temp with heavy load (even max settings) but shouldn't go beyond 80's Many thanks for your time
  6. I did not know exactly where to put this thread but i think is a good idea to discuss and share something about the thermal paste. I have read enough of this topic, and the best known brands are: IC Diamond Arctic Cooling MX-2 / MX-4 Arctic Silver 5 Tuniq TX 2 / TX 4 Extreme COOLER MASTER IceFusion I found a new one (at least i did not know) that promises to be better than the others, called GC-Extreme Solutions GELID, here are the link to a review: GELID Solutions GC-Extreme Thermal Compound Review - Page 1/5 | techPowerUp. $13 on Newegg Also found several videos on YouTube explaining the methods of applying thermal paste, and i want to share with you a couple of them: Also found some pictures here that show (basically) how to apply the thermal paste on the AW M11x, i think internally is quite similar to M14x so, if any of you know a method or have any pictures/videos/reviews that you can share i'll be more than interested in seeing them and if they are of the M14x that would be better! greetings!
