NVIDIA 840M (laptop) - logistix111 - 09-05-2015 Did some overclocking just for fun and informational testing and here are the benchmark results: OS: Windows 10 64bit Driver: 355.60 oclHashcat v1.37 Default settings for WPA = 31,400 hashes per second Default settings for MD5 = 790,000 hashes per second +135 Mhz GPU Clock Offset = 35,100 hashes per second for WPA (11.78% performance increase over stock) +135 Mhz GPU Clock Offset = 881,000 hashes per second for MD5 (11.39% performance increase over stock) Tool used: EVGA Precision X 16 software utility. Raising the Mem Clock Offset will actually hinder performance so it's left alone. Most of us know already that unless you have adequate cooling, overclocking a laptop GPU is NOT recommended! To put this into perspective, if it normally takes your word list 1 hour to complete, then: 10% increase = 6 minutes faster (54 minutes) 11% increase = 6.6 minutes faster 12% increase = 7.2 minutes faster For 10 hours, a 12% increase in performance is about 1.5 hours shaved off of your time. RE: NVIDIA 840M (laptop) - Difermo - 09-07-2015 Nice. I was w8 for some bench for GT 840M. I was comparing it shader units and speed to other cards and tought it would do 20.000 H/s But 31,400 is great. How long did you run WPA? Was it 10 minutes, 1 hour, or 1 day? How much heat did it produce? RE: NVIDIA 840M (laptop) - FlippingGerman - 09-08-2015 Really? An 840M only does 790k MD5? My laptop has a 4 year old AMD 7690M XT and does twice that, and it was not expensive. RE: NVIDIA 840M (laptop) - Difermo - 09-08-2015 That means your laptop is from 2011. Strange since AMD 7690M XT is launched 2013 RE: NVIDIA 840M (laptop) - FlippingGerman - 09-09-2015 No? http://www.notebookcheck.net/AMD-Radeon-HD-7690M-XT.72662.0.html But interestingly I only get 24.4k on WPA, 1394 MH/s on MD5. Actually Device Manager (among others) tells me I have an "AMD Radeon HD 6700 Series", but that changed after I installed modded drivers so I don't believe it. I bought the laptop in August 2012.
