It seems you're summarizing a concept about CPU performance. Basically, it doesn't matter which programs report since each program gives different results. The sticks should run at the CPU's 1333 MHz limit, and there shouldn't be any noticeable performance difference. You're aiming to choose the stick with the lowest CAS latency and a speed of 1333 MHz.

They focus on what they publish, but their methods differ, so understanding your tool’s reporting is essential. Not always. I’m not sure about your setup, but usually the processor’s memory speed limit acts more as a suggestion than a strict rule. Faster RAM doesn’t always work, though it often does. Dual channel offers double the bandwidth and better latency too. This could boost performance in some apps, but the gain varies. Not ideal.
All participants here agree, though I'll try to clarify the details more thoroughly while keeping things simple for clarity. The processor's maximum memory speed is 1333 megahertz, as mentioned on Intel's ARK page: https://ark.intel.com/content/www/us/en/...0-ghz.html. This document also shows the maximum number of memory channels it can handle and the highest bandwidth possible with that setup. It suggests your CPU can officially support 1333mhz in dual-channel mode, achieving a bandwidth of about 21.3 gigabytes per second (calculated as 1333 × 8 × 2 = 21,328 MB/s).
It's crucial to understand these limits come from Intel and don't cover overclocking beyond their stated specs. Also, keep in mind that these figures relate specifically to the CPU's memory controller ratings and aren't about the processor's operating speed. The numbers people see can differ because they're measured in two ways.
@Kilrah & @HairlessMonkeyBoy were right; it boils down to personal preference on how we interpret memory speed. Some check WMIC for "Memory Chip Speed," while others look at "Configured Clock Speed." Running those queries can yield different results.
For instance, my machine runs at 1200mhz but actually operates at 2400 MT/s. For ease of explanation, I'll treat it as a 2400mhz "effective clock." Regarding performance impact, dual-channel does provide roughly double the bandwidth compared to single-channel, though this doesn't always translate to noticeable gains in everyday tasks. Not all applications are memory-intensive, so extra bandwidth rarely makes a big difference. Reducing latency is beneficial, but that's a separate issue altogether.
Typical improvements from using dual-channel in gaming or regular use would likely be between 5% and 15%, depending on the workload. In more demanding scenarios, you might see even larger benefits.
I’m really struggling to find the right words. Also, I was discussing how 1333 MHz RAM in dual channel versus 1600 MHz in my setup works—most folks understand dual channel is essentially superior.
You're puzzled. On each cycle, the memory transfers 2 bits through every data line. The stick is 64-bit wide, meaning 128 bits are sent per Hz between the RAM and the controller. To tell these DATA-DIRECT ATEN memory sticks apart from older SDRAM (which sends just 1 bit per pin), makers began marketing them at double the actual speed. Thus, a DDR3-1600 operates at 800 MHz but is labeled 1600 because it handles twice what a 800 MHz stick could. In dual-channel mode, the controller accesses both channels simultaneously rather than one stick at a time. This means each Hz allows 128 bits from the first channel and 128 bits from the second, totaling 256 bits per cycle. If you need to save 1 MB, the controller writes 512 KB to each stick in parallel, cutting the time nearly in half while keeping the same speed (800 MHz for this example). I’ll simplify a bit for beginners—it might not be perfect—but it should help clarify things. In computers and processors, parts need to coordinate using clocks or frequencies. There’s a starting frequency, usually between 100 and 200 MHz, often called Front-Side Bus. This base is adjusted with multipliers and dividers to reach other speeds—like 100:3 or 200:6 gives about 33.3 MHz. Older PCI cards ran at 66 MHz, achieved by dividing 200 by 3. To match memory speeds, the CPU uses multipliers that jump in half steps. For instance, an FX-8320 with a 200 MHz base can change in 100 MHz increments. To sync with memory, additional multipliers or dividers are applied. In my setup, the CPU runs at 200 MHz and RAM is at DDR3-1333 (likely due to a reset). The FSB rate is about 3:10, so the RAM’s frequency comes from multiplying 199.99 MHz by 10/3, which matches closely. The clock that drives the FSB can shift slightly with temperature or design, and some high-end boards may push it higher for overclocking. Keep in mind that these adjustments can impact other connections—like PCI-E buses—if changed too much, possibly causing crashes or resets.
