This may not be obvious at first and you might only discover these crashes while the system is being used under load.Īll of the above reasons are why you should use identical sticks of RAM of identical size whenever possible. Speeds are usually labeled using either the older standard (in which case you’ll see speeds like PC2/PC3/PC4) or the new standard that also includes a more specific speed rating (in which case a speed would look more like DDR 1600). One other factor you should consider is that subtle differences between mismatched RAM can cause system stability issues and crashing. RAM Speed: This is based on a rather complicated combination of hardware factors, and the relative speed of RAM is specific within a generation. ![]() ![]() This won't be any worse than what you had before adding the extra RAM, you just are not taking advantage of the full potential of your memory and your CPU - see this The other issue is the mismatch memory size will affect your Dual-Channel memory performance. It will not damage your system or the RAM. You just are not getting the advantage of the higher clock speed of the new faster RAM. Since the slower chip is what speed you were already running at, you wouldn't see a performance decrease. In my case i have installed lower speed, So will it make the RAM(2667 MT/s) to work on 3200 MT/s speed.Will my system pressure it? Does it cause damage to my system or default RAM or new RAM?Īnd Locator, Serial Number, Asset Tag, Part Number are also different.Īs long as the RAM is working and being recognized by your motherboard, the faster chip will run at the same speed as the slower chip. So, if you Installed one stick with 1600Mhz and other with 2400Mhz, the latter will work on 1600Mhz, thus lowering its efficiency. If you install two RAM sticks of different frequencies, both of them will be working on the lowest frequency. pc:~$ sudo dmidecode -t 17įrom my above details, i can see that Speed is different(default: 3200 MT/s, newOne: 2667 MT/s). I read about RAM in google that: Speed, frequency, Latency, Clock Speed, Size matters for RAM.īelow is my RAM details, in that Manufacturer: SK Hynix is the RAM dell already installed in my laptop. Since its emergency, i went other service centre and changed(with different number "2666" RAM, manufacturer: Crucial). Otherwise increasing RAM is cheap and always good as Vince mentioned, but maybe not the issue here. ![]() You will notice it as the whole system feels like it is hung up for some seconds from time to time. If the RAM is full it will be extremly slow as it starts to swap to HDD. So we need to wait to get exact number for upgrade. More RAM will not much fasten up that specific issue. A more drastic option to speed up your laptop is to install a Linux distribution instead, such as Ubuntu, Kubuntu, Mint, Dolphin, etc. They told he has different number like "2666" but in my system RAM its number is different.
