| 1367986 | 2014-02-18 03:56:00 | My original system was having 2x4GB Kingston HyperX - KHX 1600CD9D3k2/8GX and BIOS detected it as Dual-channel - all good. Just got myself another set of G.Skill RipjawsX 16GB (2x8GB) DDR3 1866MHz, insert them into my system, booted up OK and it BIOS shows 24GB, 1600MHz, but the 'Dual-channel' is gone! Why is it so? Could someone please enlighten me? Thanks. |

| 1367987 | 2014-02-18 06:31:00 | Do you have a motherboard manual? Reason I ask is that the RAM has to be installed in the proper slots to work. Not too sure but you might find that the combo could be same size RAM in slot one and three, two and four. Or is it the same size in one and two, then three and four. The motherboard manual would tell you. |

| 1367988 | 2014-02-18 06:57:00 | Dual channel means identical ram / brand and speed. Thats why its no longer dual channel. Two are Kingston and 2 are G.skill. Dont know if all of the sticks have to be identical. Some mobos may support it, if two are in the right slots | Speedy Gonzales (78) | ||
| 1367989 | 2014-02-18 07:31:00 | Take out the two smaller sticks, then you will have dual channel. 16GB is any amount. It may even run better than having two unmatched sets. |

| 1367990 | 2014-02-26 01:01:00 | dual channel need not have identical sticks. same size is sufficient. mismatched speeds will simply run at the fastest mutually supported speed. identical sticks are only note worthy for identical timings and other specifications which do make little difference out side of benchmarks and other epeeen type obsessions. 1% type performance situations. same warranty for all your sticks is a good reason to keep matched pairs you may find that dualchannel does not significatly affect performance depending on the task you use your system for. 16GB is definitely enough. sell the 2x4GB sticks and consider buying more 8GB sticks later |

| 1367991 | 2014-02-26 02:10:00 | Actually Mirrdes the move to matched pairs of Identical Sticks was a response to the numerous stabilty and memory error issues that occured when dual channel was first introduced. Well in theory any two compatible Sticks of matched size can work in dual channel mode in practice it can be very hit and miss, hence the move to matched pairs. RAM that works perfectly as individual sticks will not always work in pairs or mixed with other RAM sticks. On top of that different brands or Speeds of RAM don't always coexist well, and the problems can be very intermittent and lead to a frustrating situation where an otherwise stable system will occasionally get unstable for no apparent reason. It doesn't hurt to Mix RAM and see what happens as long as you are prepared for potential issues, but when you have the option you should always try for matched sets. |

| 1367992 | 2014-02-26 04:55:00 | In general mixing different brands\speeds of RAM is just a bad idea, dual channel or not. Sometimes it works but you can also get very intermittent and strange problems. | Agent_24 (57) | ||
