System fails to boot or shows no visual output after the RAM upgrade.
I improved my Lenovo ThinkBook 14 IIL from 8gb to 16gb Corsair vengeance 3200 mhz cl 22 ddr4, but the display isn’t showing anything. I’ve reset the CMOS, tried two different RAM kits, and still have the same problem. When I reinstalled the old RAM, everything works fine. Could it be that the system only supports 2666 and using 3200 MHz is causing issues? Or maybe the fact that it wasn’t SK hynix RAM could be the problem?
This scenario is highly improbable, as the system would likely revert to a reduced performance mode. The BIOS would need to be poorly crafted to achieve this, which is unlikely given the standards expected. It’s more plausible. In general, there are several memory ICs compatible with any given stick, each requiring precise settings determined through training. It’s conceivable Lenovo didn’t tailor their BIOS for the newer ICs in your sticks compared to older models. Including photos of both kits would help clarify the differences, as with Corsair products you can often identify the memory type from labels, and with SK Hynix you can usually determine it by checking the model number or packaging.
The Corsair component is already installed, but the packaging label matches exactly what you saw online. I attempted to figure out which chip manufacturer produced the Corsair RAM, but the status indicator doesn’t show the version details linked to Corsairs’ site for various chips: SK hynix module: Appreciate the assistance.
For Corsair modules, the chip is usually located directly on the stick. A few units display a label like "Ver. 4.31," which decodes to the memory IC. Not all sticks include this marking, so if it matches, it’s likely one of them. You can’t rely solely on the model number because RAM makers often change the IC in a kit based on what they have available that day. The SK Hynix kit is an 8Gb JJR type, which isn’t a widely known IC.
Yes, that seems correct. Replacing the kit with one that shares the same IC would likely be the optimal solution.
Thanks for your assistance. It seems the item isn't available for retail purchase in the UK, but I located a suitable eBay listing which should resolve the issue.
