High performance RAM is generally not recommended for budget systems. You need 1.2V memory and can install either in pairs or single modules, but mismatched modules will not run in full dual channel mode. If you want Kingston RAM, here's what they recommend: [URL] Another alternative: [URL]
Hi, after runnning CPU-Z I found that this model comes with 04TPRN A00 mother board, which should be usefull to find info about which RAM specs will work, but as it seems, is not. After running Kingston and Crucial memory checks I found that the compatible specs for the Vostro 15 5510 system are: DDR4 3200MHz Non-ECC Unbuffered SODIMM CL22 1RX8 1.2V 260-pin   The catch is that high performance RAMS are mostly 1.35V voltage. Does anyone know if that would be an issue? Also, you can buy RAM memory that comes in a single stick (for instance 32GB) or kits with 2 memory sticks that come together (for instance 32GB - 2x16GB). Does anyone know if using to single sticks of same specs works the same as using 2 sticks that come in a kit? So let´s talk specifics. Does anyone know if these specs are compatible with the mentioned vostro system? - Kingston Fury (KF432S20IB1K2/32) - Memory kit 32GB (2 x 16GB) SODIMM DDR4 3200Mhz FURY Impact 1,35V 2Rx8 260 pins - Corsair Vengeance Performance  (CMSX16GX4M2A3000C18) - Memory kit 16GB (2x8GB) SODIMM DDR4 3000Mhz CL18 1,2V - Crucial Ballistix (BL2K16G32C16S4B) - Memory kit 32GB(16GBx2) SODIMM 3200 MHz CL16 DDR4 DRAM 1,35V - Crucial Single Stick (CT16G4SFRA266), 16GB, DDR4-2666, sodimm 1.2V CL19 All the best, Pedro_S.
