Albuquerque Posted December 8, 2011 Share Posted December 8, 2011 Greetings, I'm on my second pair of these 8Gb SODIMMS (first pair RMA'd through NewEgg) and it appears these chips are not compatible with this system. Details are as follows: Device: Lenovo Y460 Processor: i5-520m 2.4Ghz "Arrandale" Chipset: HM55 Prior Ram Installed: 2x4Gb DDR3 1066 7-7-7-20 (competitor brand, sorry) New Ram Module #1: Lot 2429946 / SN 114506380 New Ram Module #1: Lot 2368006 / SN 114403960 New Ram Module #1: Lot 2367752 / SN 114403960 New Ram Module #1: Lot 2367824 / SN 114403960 Video: Switchable IGP 3000 / AMD 5650M 1Gb Firmware Version: 71 (27CN71WW) dated Feb 17, 2011 Is it odd that three of them share the same serial number? Hmm... The BIOS configuration screen correctly shows 16384Mb installed, however all four chips exhibit the same problems on this platform. When installed as a pair, they fail Memtest86 4.0a at Test #1 / 15% or will fail to boot Windows with a black screen / hang. When installed singly, Memtest will randomly hex-dump or the screen will become corrupted and Windows will BSOD with the generic "Any new hardware you may have installed isn't working" message. It's an i-series processor, and it's the proper chipset, so in theory it should work. However, since both sets failed in precisely the same way (even down to the exact same failure point of test number and completion percentage in Memtest86) this makes me reasonably confident the failure is with my machine rather than your ram.

Albuquerque Posted December 9, 2011 Author Share Posted December 9, 2011 I figured as much, and so did a few coworkers of mine who would probably know. :) I might take a swing at reverse-engineering this BIOS, but cooking Lenovo firmware typically is a pain in the posterior region. :( Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted December 9, 2011 Corsair Employee Share Posted December 9, 2011 I would maybe try and contact their support and keep complaining till you get to a support person who actually works for Lenovo. Link to comment Share on other sites More sharing options...
