Most dual-channel memory controllers will operate properly in single-channel mode if you install only one DIMM, but system performance may be significantly degraded. I'll assume familiarity with common terms like Megabytes and Gigabytes etc. As shown below SpeedFan tells me I have only one RAM stick (DIMM #0) and it is DDR, it does not store parity information, and the total size is 512MB. allenw1223Apr 15, 2009, 11:38 PM jitpublisher said: Memory runs in banks. 2 slots make a bank, your board should have colored slots representing the matched banks.

ECC - Error Correcting Code - RAM that has additional data storage for checksum bits to allow correction of errors 'on the fly'. Because the RAM is Dual Data Rate the memory bus runs at 200MHz in this example but the equivalent DRAM Frequency would now be 400MHz.)

Ram Memory Different Frequency
Some versions of the Award BIOS slow down your system markedly when more than 768MB of RAM is installed. Also, because the circuitry on ECC modules that calculates and stores ECC values imposes some overhead, ECC modules are marginally slower than similar non-parity modules. techwanabe Diamond Member Joined: May 24, 2000 Messages: 3,147 Likes Received: 0 Almost 3 years ago I bought a Dell Dimension PC with 3.2 Ghz Pentium 4.

The 'chunk' of RAM is then declared free for use. With the introduction of the 168pin DIMM this drawback was overcome and now there can be many banks of RAM on one memory module. Ram Memory Different Frequency Faster, larger and more expensive than DRAM. Is It Safe To Use Ram Sticks With Different Frequencies No-one likes a slow computer so what do you do about it?
Replace the Cover. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. RELATED ARTICLECPU Basics: Multiple CPUs, Cores, and Hyper-Threading Explained DDR4 RAM made its first appearance last year as part of the Haswell-E rollout. If you put a single odd stick into 1 slot of a bank, your memory will not run in dual channel mode. Can I Use 4gb And 8gb Ram Together
GET IT RIGHT THE FIRST TIME The easiest ways to avoid motherboard compatibility issues are to verify the compatibility of specific memory modules by brand and model on the motherboard web Re-arrange the memory so it gives me the advantage! By the time Windows 98 came out these had become 16MB or 32MB modules to make up around 64MB in a good system. useful reference Move a single match to make this expression true Are the Ferengi racially discriminated against by members of the Federation?

In fact, many people erroneously look at a computer and call it a CPU or a hard drive, when in fact these are just two parts of a computer. If you know about the other memory timings, you can also try fiddling with those. You can also often identify an ECC module by its part number.

Some controllers support X4, X8, and X16 modules, but many support only one or two of those organizations. Single-sided DIMMs count as one row, and double-sided DIMMs as two rows.

So 1GB + 2x512MB should workClick to expand... If you're currently using two different DIMMs at different speeds, it's best to replacing them with matching speeds (and timings if possible). Similarly, once all the required data in a row has been read a different row needs to be addressed. The PC originally came with 2x512MB modules.
My new ASUS P5Q Pro http://www.xbitlabs.com/misc/picture/?src=/images/mainboards/asus-p5q-pro/board.jpg&1=1 has Dimm_1 Dimm_2 together as yellow and black and Dimm_3 and Dimm_4 as yellow and black so this is the case where 2 different colors Remove the PCI card. This will indicate for example whether the Memory Controller can support Dual Channelling, which you will need to consider if you are upgrading. This tab also tells me the timing figures are 2-2-2-6 @133MHz. (See the 'Memory Latency' section for an explanation of these figures).
Static is especially a problem during dry weather and if you have synthetic carpets or clothing. If I had more than one stick there would also be information for DIMM #1, DIMM #2, etc. How much RAM do you need? "640K should be enough for anybody." - Bill Gates 1981 Ironic that this quote should come from the founder of Microsoft - the company whose The parity of each data byte can then be stored by adding an additional bit of data, which can be either a one or a zero.
When Windows has loaded okay run CPU-Z again to check the new memory has all been recognised and is running at the correct speed and in the correct mode. Inserting the new RAM is a matter of choosing which slots to use (if your are not using Dual Channelling then just use the next available slot). If the amount is not equal, they can run dual over some of the ram, and single over the rest.Click to expand... Older systems may have less user-friendly mechanisms, but all of them use a mechanical latch at either end of the module.
If you're running an outdated motherboard or a non-compatible processor for example (such as older Haswells or AMD equivalents), you'd need to upgrade those as well to use DDR4 RAM.
