But in each case, the system will clock down to match the slowest memory module it has access to, so buying faster RAM to mix with slower RAM doesn’t have any real benefit. That way you get these temps, yet remain silent. If you’re limited on time, this is a good way to test both the CPU and RAM at the same time. For example, they may bin their kits of RAM at 1.35 volts, not do extended testing if it doesn’t pass, and chuck it in the “3200 Mhz mid-tier bin” that most kits of memory fall into. Most users understand that a faster processor, with speed expressed in megahertz or gigahertz, is more desirable. Right now I'm seeing the highest temp I've recorded yet, on on a build with 8GB (4x 2GB) of older A-Data AD2800002GMU DDR2. Here is the dump. Some RAM handles itself really well at 4000+ Mhz with low CAS latency, and some RAM can’t overclock past 3000 Mhz. Joined Dec 6, 2008 Messages 1,388 (0.33/day) Location Macon, Georgia System Specs. Most RAM buying guides, including ours, insist that 16GB is the value sweet spot, and for good reason: Many consumer programs tend to spill over 8GB of … It's DDR2 800 memory running DDR2 887 @ 1.9v if I recall correctly, in a case and system configuration that doesn't put a lot of airflow over it. He spent five years writing for Android Police and his work has appeared on Digital Trends and Lifehacker. Thanks fir the feedback guys! But what if you ran the memory at 1.375 volts? While faster, lower latency RAM will indeed increase the technical performance of your computer, it works at such a fundamental level that it’s almost impossible for us flesh-and-blood humans to actually appreciate the difference. CAS latency is a measure of how many clock cycles there are between the READ command being sent to the memory stick and the CPU getting a response back. Lower latency means faster data access, thus faster data transfer to the CPU, and faster operation of your computer overall. Speccy. Not all RAM performs the best. Total: 1,130 (members: 42, guests: 875, robots: 213) Then, once you get it working, you’ll need to verify the overclock is stable using the calculator’s built-in memory tester. For a while now I've been checking RAM temps in my builds. 12800 divided by eight is 1600, so it’s two ways of stating the same thing. This is because of XMP (Extreme Memory Profile). The XMP speed is just a rating that guarantees that stick of memory will perform at the rated speed 100% of the time. Press the purple “R – XMP” button to load your kit’s rated specs, and then press “Calculate SAFE” or “Calculate FAST” to view your new timings.You can compare these timings with the rated specs using the “compare timings” button, and you’ll find that everything is tightened up a bit on the SAFE settings, and the primary CAS latency is reduced on the FAST settings. Since we launched in 2006, our articles have been read more than 1 billion times. The “stock” speed for DDR4 (the newest memory type) is usually 2133 Mhz or 2400 Mhz. With that going now, the temperature in the same spot (probe hasn't moved and room temp has remained constant) doesn't break 50° C. That fan is key to balancing the airflow in the case, but I'm still surprised it made an 8° difference. Pretty simple, right?Things start to get complicated in the nomenclature.
Once it’s loaded, it usually stays there for a while, being accessed by the CPU whenever it needs it.Improving the speed at which your RAM runs can directly improve your CPU’s performance in certain situations, though there is a point of diminishing returns when the CPU simply can’t churn through more memory fast enough. It’s more about marketing and product segmentation than it is about the limits of the RAM; nothing prevents your RAM from operating outside of the manufacturer’s spec, other than that enabling XMP is easier than overclocking it yourself.Additionally, the factory binning process will have a set voltage range they want to operate in. Obviously at 50-something Celsius, you have a lot head room.
