Just Bought New Ram and It Wont Read
RAM is ane of the almost essential parts of your desktop computer, and it'southward also ane of the quickest and easiest parts to upgrade. Mod RAM modules are incredibly simple to use, then information technology's rare that something goes wrong in installation…but then when something does go wrong, it gets frustrating quickly. If your computer or operating organisation doesn't recognize the RAM y'all're using, here'due south what you lot need to do to detect the problem.
Stride One: Check The Seating
On a desktop, installing RAM is uncomplicated: fold back both the clips on the RAM slot, then insert the stick firmly straight down. The pressure from your insertion should force both clips to snap back into a locked position with an audible "click," but sometimes it does crave you to snap them back down on the DIMM manually. If the DIMM isn't exactly perpendicular to the slot and the motherboard, or the clips can't be completely snapped, it's not fully inserted. Remove the DIMM and attempt again.
Laptop designs, due to their lower tolerances for space and volume, are a little trickier. Assuming your laptop allows admission to a RAM DIMM slot at all (many newer, smaller designs don't), the DIMM is generally inserted at an angle, then pushed down towards the laptop frame until it clicks into place. Even a properly-inserted DIMM might not exist seated properly; be sure to put as much pressure on the stick as yous can without risking harm to the excursion board itself.
Step 2: Cheque Your Motherboard's Compatibility
RAM DIMM sticks are fairly standard and well-designed: they can only be inserted one fashion on both desktops and laptops, desktop and laptop RAM isn't interchangeable, and dissimilar generations of RAM won't fit in the incorrect socket (and then a motherboard that but supports DDR4 RAM can't physically fit DDR3).
That being said, it'due south rare just possible that RAM might not exist compatible with a motherboard, even if it's the right blazon. RAM speed should dynamically shift down if information technology's faster than the slot itself can handle, and timings shouldn't accept an impact on the compatibility at all. But it's possible the RAM DIMM's capacity is college than the motherboard is rated for.
Your motherboard has a maximum amount of supported RAM, which includes all the slots on the lath taken together. This might be as few as ii or equally many as eight, but about full-sized (ATX) motherboards include four. So a motherboard with a maximum RAM chapters of 16GB and 4 RAM slots can simply accept a maximum of 4GB in each slot—trying to put an 8GB DIMM into the slot might cause information technology to not be detected. This is probable to be the case if you lot've bought multiple new DIMMs and all of them are failing.

Footstep Iii: Run a Diagnostic like Memtest86
If you've checked all of the above and still can't find a reason that your RAM isn't beingness detected, you might have a faulty DIMM. It'due south possible to determine this with software tools.

Windows includes a built-in memory diagnostic tool that you can run, if your arrangement can boot without the RAM you just replaced. If y'all tin can't boot into Windows or you're running Linux, the MemTest86 tool or MemTest86+ can run pre-boot and isolate problems in the same way. This guide volition show yous how to utilize both methods.
If the retentivity examination returns detected errors, you probably have a faulty RAM DIMM. It'due south fourth dimension to supervene upon it (and remember to return it to your retailer or manufacturer if it's within the warranty period).
Stride Four: Make clean the Electrical Contacts
If your RAM is showing errors or isn't being detected, it'due south possible that some of the contacts on the DIMM might have gathered dust or some other obstruction. To clean them off, employ a elementary cotton wool swap lightly dipped in 91% isopropyl alcohol to swipe each contact. (Don't utilize a conventional cleaning contact, every bit the chemicals might cause corrosion.) Make certain to let the alcohol completely evaporate, and check the contacts over for any balance dust or cotton. If you have some compressed air handy, give each side of the DIMM a quick blast. At present re-insert it and endeavour again.
Step Five: Test It With Other Systems
If even a retentiveness diagnostic isn't returning any results, you may have a more serious trouble. The mistake is either with the RAM—an abrasive merely relatively piece of cake part to supersede—or with your motherboard, which would exist a much bigger pain to remove. At this point you want to know why, because one failing part on a motherboard can easily lead to others, and that means a completely broken computer sooner or later on.
The following steps might not exist possible if y'all don't have some extra hardware at hand. If yous don't, enquire a friend or coworker; yous might become lucky.
Attempt to detect a computer that'southward similar to yours. If yous can employ a estimator that's in working status that has the aforementioned RAM compatibility (the same DDR revision and a slot that can take the capacity of the DIMM), swap the possibly faulty memory into the second figurer and run across if you meet the aforementioned problems. If the reckoner boots and detects the new retentiveness, the problem lies somewhere else your organization, not your memory.
At present test information technology in opposite. Put another DIMM into your original computer in the same slot, again, with the same stipulation that it needs to be compatible with the motherboard. If your original figurer boots and detects the RAM where it didn't earlier, the issue is with the original memory, and that needs to be replaced.
