Mixing ram sizes Forums. I see that if I mix RAM capacities in my IMAC, for instance keeping the base 4gb in slot 2 and 4 (DiMM 0), and then add 16gb to slot 1 and 3 (DIMM 1), my RAM speed in "System Information" drops from 2667 MHz to 2133 Mhz. The size, speed, and voltage of RAM sticks may produce varying results, but different brands will not. I know that mixing two sizes will either drop speed or lose dual channel. I already bought 2 sets of G. Find out what the specs of the RAM you have installed are and match it as close as possible. A) 2x4G Original Apple SK Hynix. But whether the system boots is uncertain. However, you may not be able to enjoy any advanced benefits of the With AMD it is less official but it appears that since AMD's 7xx northbridges for AM3 have operated RAM in unganged mode (that is, two independent 64-bit channels), benchmarks have shown that you do indeed get dual-channel bandwidth when mixing RAM sizes this way too, until the matched sizes run out. Some users are also curious about “can you mix RAM brands?”. If you mix RAM size, each That's only if you use mixed size ram on the same channel, like having only a 4gb dimm and another 8gb one, those would run in flex mode (4+4gb running in dual channel, the remaining 4gb in single channel). Is the one at I am still unclear about mixing ram. Memory . In the past, I have seen Dell manuals with a full capability chart for RAM. Although you can mostly mix RAM sticks that have different specs, you Mixing RAM modules of different sizes is fundamentally fine so long as the generation, speed and primary timing are matched exactly or at least as closely as possible. To obtain the best system performance, it is recommended to use RAM sticks from same manufacturer, with identical sizes, and of the identical frequency. Modified 4 years, 11 months ago. It's bad if you need more than 8GB of memory a lot of the time, as you will see a reduction in memory bandwidth, if the system memory usage exceeds 8GB. Examples: 1 GB, 2 GB, 4 GB. 5v in 1+3slots If I get another set of RAM lets say 2x2GB 1600mhz CL9 and put them in slots So somebody parroted to me the common myth about how "you shouldn't mix RAM sizes because it can damage computers. I was wondering if it is possible (and safe) to have two separate pairs of ram in a four slot motherboard. Matched in symmetrical memory slots. One difference between DDR and DDR2 is DDR2 ram should be installed in pairs. Nov 26, 2016 5 0 1,510. About mixing ram kit, sometime they work sometime they don Look for the ram QVL list. Same brand same speed and I'm pretty sure same size too. Aug 13, 2016 #1 I have Corsair Vengeance 2133mhz 2x4GB Dual channel CL11 1. is it better to consolidate each brand to a specific channel or mix them up. I tested a mix of two kinds of memory sticks with different size capacities and different benchmarks results. i want install another ram with same specifications but with 8gb volume. My q asking if the different ram sizes would prove destructive towards the performance and ultimately ruin the DC efficiency. I believe it was because the DIMM SPD didn't provide correct settings for the BIOS to use. Mixing Speeds: Adding a 3200MHz RAM to a 2400MHz setup will cap the faster RAM at 2400MHz. RAM sizes refer to the capacity of each RAM stick and how much information it can store. Generally, you're just gonna have the lowest common denominator of the sticks' performance specs. For example if the 16gb sticks are 3600 MHz and the 8gb sticks are 3000 MHz, then ALL ram sticks will run at 3000 MHz. Half of the times a computer will run just fine when mixing different brands, sizes and speeds. Both sets are same speed same latency, just different sizes. • Populate four DIMMs per processor (one DIMM per channel) at a time to maximize performance. As long as the different branded RAM sticks share the same technical specifications, there shouldn't be any problems. This lets matched memory portions work in dual-channel, possibly @Cabbage it depends completely on the motherboard/memory controller. Reply reply You can mix speeds, however all sticks will be limited to the lowest common frequency. If you go to quad-rank, your RAM speed will drop to 800 MHz (row 4). If you If you want more capacity, pick the same ram kit that you currently have (if your motherboard has two more ram slots) or purchase a higher capacity as a dual channel ram kit Whether you’re looking to purchase a new set of RAM or upgrade the amount of existing RAM on a computer or laptop, one of the most common often comes up: can you mix RAM sizes/modules? What if there are different but the rams that I'm gonna buy is totally the same, only the sizes aren't, so it still has impact for dual channel? Yes, DDR4 RAM can be mixed in a computer system. Thread starter brkdvvn; Start date Aug 13, 2016; Toggle sidebar Toggle sidebar. Open comment sort options I'd be matching the existing Ram manufacturer, type but adding Ram of a different size. 83. The memory controller generally runs all attached RAM So I am building a high end pc for myself with a Asus ROG Maximus z790 Hero and a i9 13900k (to put you in context). I've heard that mixing different rams with different sizes should work if they use the same frequency and voltage, at the cost of some performance loss. This was about 5-10 years ago, though. I have been running 24gb with different sizes for years. Unsolved. Mixing ram sizes (same brand/speed) So currently i have CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000) and was wondering could i get the exact same kit but with 2 x 4GB bringing my total to 24? It has four slots for RAM. #shorts #gamingpc #pc #pcbuild #gamingpcbuild #ram #ddr4 #ddr5 #ddr3 #pcbuilding #pcbuild If you want 16 GB RAM then you would want either 2x 8 GB or 4x 4 GB all the same. When I opened the laptop I was surprised to see one of the ram slots is soldered (4GB 2666H) and the other one is removable. I wanted to put 2 more in because I find myself struggling with some games. In a 4-channel configuration, the DIMMs work together, so it doesn't matter what size they are or even what speed they are (2133, 1600, 1866 MHz). This is the mix that is in my laptop, which only has 2 DIMM slots: As you can see, I have two different manufacturers and two different speeds. When buying new parts for your computer, you may wonder - can you mix RAM brands? This article explores RAM and answers whether or not you can mix On an Intel CPU you would indeed have the same thing as before, only with 32 bit dual channels per controller, so 16 GB 32 bit wide quad channel and 8 GB 32 bit wide dual channel memory. Currently have 2 - HP 16GB DDR4 2933 MHz Registered ECC Memory modules and looking to add 2 - HP 32GB DDR4 2933 MHz Registered ECC Memory modules that would bring up to 96GB. e. at least I have never had any issues. AFAIK RAM have to be the same size to enable dual channel, which for gaming matters a lot. Mixing rams with different frequencies and sizes. so I'd be adding 32 GB of Ram--2 sticks of 16 (Kingston Fury) DDR4 to an existing pair of 2 8GB ddr4 Kingston fury. The faster RAM will also run at a frequenc Most people only need 8 or 16 gb. Well, by the chart above, it appears that you cannot mix memory size. This is because when mixing, the physical memory will be recognized, but the total RAM will perform at the highest latency. It might work if you clock it to 3600 and give it a little extra voltage on the ram and memory controller. More posts you may like r/buildapc. All the memory units installed in a motherboard run at the same frequency. Your existing RAM is 1333 MHz, so you are in the top row of the table. 2x4 GB 1600 MHz.

The best option in your case is upgrading to two of these 3200MHz 16GB sticks with the same size and speed. As clock speeds go, it will default to the lowest speed out of all your ram sticks. speed differences in RAM make little, if any discernable difference to performance. However I couldn’t find a definitive answer on mixing sizes or vendors. ) Does all the RAM still have to be identical? Your computer’s random access memory (RAM) is one of its core parts. However, I found a good deal on another set of RAM, the Corsair Vengeance 32GB (16GB x 2) 3200MHz DDR4. You can mix manufacturers.

Thanks. Two slots already have 8 GB sticks of Dell DDR5 UDIMM 4400 MHz RAM. turn on suggested results. The correct thing to do would be to have all memory modules be identical. However, there are Technically, you can install memory units with different speed and latency. Reply reply Once you've verified these, the next thing to keep note of is whether the RAM is the same size. Unless CPUz is a piece of shit software which shows incorrect things (and also all the ram benchmarks which showed me an increase in bandwidth compared to single channel ), populating all the slots with identical brand, CL and speed RAM will work and give you dual channel. The thing is, when you mix memory modules with different frequencies and timings, you get the worst of both worlds: all modules have to run on the clock and timings appropriate for the slowest one. •Place the DIMMs with the highest number of ranks in the white slot when mixing DIMMs of different ranks on the same channel Top 1% Rank by size . As for the result, that PC never awoke again. This means that if you have DDR2, you shouldn’t use it with DDR3. So I you want to put all 1 gig sticks in the system then you are ok with doing that.
