Thinkpad W520 Ram Slots

7/13/2022

Lenovo ThinkPad W520 Processor, Graphics, RAM, Storage The W520 includes the dual-core i5-2540M and i7-2620M, and quad-core i7-2720QM, i7-2820QM, and Extreme Edition i7-2920XM. Dual-core systems have two SO-DIMM slots, while quad-core models have four, supporting up to 8GB and 16GB of DDR3 RAM, respectively. Lenovo ThinkPad W520 42844CU laptops technical specifications database. Number of Total Memory Slots: 4. Memory Card Reader: Yes. Network Lenovo ThinkPad W520. Ok I just got my brand new spanking W520 today I have a question re: upgrading the memory It came with one 4gig stick which is in one of the slots under the keyboard and there is 2 slots open under the bottom of the case So. To install my 2 sticks of matching 4gig Ram I had waiting. You'll want the ramaxel memory in slots 0 and 1 so they're paired, then the hynix in slot 2. ↳ ThinkPad W500/W510/W520 and W700/W701 Series. The lower RAM compartment houses a single memory slot on the T520, whereas the workstation-class W520 has two slots on the bottom. The compartment also gives you access to one of the screws which holds the keyboard in place (which you need to remove if you want to get at the rest of the components up above).

Installed on my W520 I have 1x4GB Hynix memory HMT351S6CFR8C-H9

I bought 2x2GB DIMM modules of Ramaxel PC3-10600S
part number is RMT1970ED48E8F-1333
this should be the specs page: http://ramaxel.com/eng_Products.aspx?Cl ... 46%2c77%2c
If I install all of three modules, Bios and Windows 7 64bit does not see new modules, but Speccy (http://www.piriform.com/speccy) does,

If i leave only new modules, the laptop does not boot

Ram specs seems to be identical: is there any reason why the system does not see correctly this memory??
