In addition to double pumping the data bus as in DDR SDRAM transferring data on the rising and falling edges of the bus clock signal , DDR2 allows higher bus speed and requires lower power by running the internal clock at half the speed of the data bus. The two factors combine to produce a total of four data transfers per internal clock cycle. Alternatively, DDR2 memory operating at twice the external data bus clock rate as DDR may provide twice the bandwidth with the same latency. Both performed worse than the original DDR specification due to higher latency, which made total access times longer. These chips are mostly standard DDR chips that have been tested and rated to be capable of operation at higher clock rates by the manufacturer. Such chips draw significantly more power than slower-clocked chips, but usually offered little or no improvement in real-world performance. DDR2 started to become competitive against the older DDR standard by the end of , as modules with lower latencies became available. During an access, four bits were read or written to or from a four-bit-deep prefetch queue. This queue received or transmitted its data over the data bus in two data bus clock cycles each clock cycle transferred two bits of data. DDR2's bus frequency is boosted by electrical interface improvements, on-die termination , prefetch buffers and off-chip drivers. However, latency is greatly increased as a trade-off. Thus, DDR2 memory must be operated at twice the data rate to achieve the same latency.

However, latency is greatly increased as a trade-off. Based upon the general input here, this answer is "no, ddr2 6400. Does it Fit your Dell?

This category of RAM is crucial for users looking to improve their system's responsiveness and handle more demanding applications. Users should verify their laptop's specifications to ensure the memory module will function correctly. It's particularly beneficial for applications that require substantial memory, such as photo editing software, video production, and gaming. The increased RAM allows for better multitasking and can significantly reduce lag and system freezes. Despite being an older generation, it still offers a cost-effective solution for extending the life of existing laptops.

At this point, mainstream users should go for branded DDR memory. DDR is important for systems based on AMD Phenom processors, as their memory controllers can utilize the faster memory. At this point we recommend waiting on purchasing DDR3 memory, as most speed grades are still considerably more expensive than DDR2 RAM, without delivering better performance.

All parts are physically in-house, and ready to ship same business day. Sign in. Archived from the original PDF on Despite being an older generation, it still offers a cost-effective solution for extending the life of existing laptops. Enter your 7 character Dell Service Tag is located on the bottom of your laptop. In other projects. The lower memory clock frequency may also enable power reductions in applications that do not require the highest available data rates. DDR2 memory can function at a wide range of clock speeds and the programming of CAS latencies, etc is pretty standard and based on the number of clocks. Read Edit View history. If it would work and if so would it allow for the faster speed. Click for larger image and additional views. However, latency is greatly increased as a trade-off. That will show current and past invoices, and gives you a pay now function. Second generation of double-data-rate synchronous dynamic random-access memory. Page content loaded.

It used to be that they had to operate at the same speed or a multiple in order to properly synchronize, but it's more advanced than that now. The two factors combine to produce a total of four data transfers per internal clock cycle. Source on Alibaba. It seems that you can get it to work with one caveat. Ask a question Reset. These chips cannot achieve the clock rates of GDDR3 but are inexpensive and fast enough to be used as memory on mid-range cards. DDR: Revenge gained". Mar 29, PM in response to Kappy.
