Can I Mix Different Types Of RDRAM?

The big difference between DDR and SDRAM memory is that DDR reads data on both the rising and falling edges of the clock signal. Single channel modules come in 168 or 184 pin configurations and both types of modules are interchangeable in most systems. You want to run an AMD Duron 1.3GHz processor on the motherboard's front-side bus (FSB) that runs at 200MHz with this processor installed. more hot questions question feed about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation Science

Why is this? Your RAM will only run at the speed of the slowest DIMM, unless you wanted to overclock the others. So, in this case, the processor is creating the bottleneck by having an effective data transfer rate that is 133MHz slower than the RAM. Why does Ubuntu not ship with a way to fill in PDF forms? http://www.lifehacker.com.au/2010/07/what-are-the-rules-on-mixing-two-different-types-of-ram/

That said, if you absolutely have to mix them, here are some general guidelines. Answer Even though the processor has a maximum speed (frequency) of 1.3GHz (1300MHz), the effective data transfer rate of the processor is limited to the speed (frequency) of the motherboard's FSB, It was named PC 2100 because it has a data bandwidth of 2.1GB per second.

First, let's start with a quick review. Sorry, I know you don't want to hear this — that depends. In theory, if you had to, you could mix, say, this Patriot model (DDR3 1333) with this Corsair model (DDR3 1600), since they have the same cas latency, timings and recommended Rambus RDRAM FAQ Can I buy memory directly from Rambus?

No, Rambus licenses RDRAM technology to manufacturing partners, but does not sell components or modules.

What Japanese word is used as a classification for all profanities? Thus, it's possible, but note that when you start mixing speeds, a chain is only as strong as its weakest link, so to speak.

Here's our analysis of the world of PC memory as it is being shaped by DDR. Even though there are systems that support both technologies, you can't have DDR and SDRAM in the same system at the same time. DDR SDRAM uses a new technique to transfer data that effectively doubles its speed. RDRAM-enabled chipsets include: SiS R659 (4-channels), SiS R658 (dual channels), Intel 850E, 850, 960, 840 (dual channels), Intel 820.

That probably won't be clear until sometime in the near future. Reply 0 Badmus Rukayat Guest Nov 30, 2010, 10:50am thanks for explanation but i dnt really get the fact am looking for.

If you've got your own tips and experiences mixing RAM, share them in the comments.

None of this necessarily guarantees functioning RAM, of course — you may be greeted with the Blue Screen of Death if your DIMMs just don't like each other (or your motherboard You must set the RAM clock speed (in the BIOS, or by setting jumpers on the motherboard) to the speed of the RAM that your purchase.

The new 1006MHz (1.006GHz) Rambus RAM, combined with Intel's 850E chipset and the latest Pentium 4b processor, takes full advantage of the latest 533MHz motherboard front side bus (FSB) frequency. I am told there i need to put the larger RAM sticks in rimms 1 and 2. Cheap, no-brand RAM can be especially prone to failure if the processor has been overclocked to a faster speed than its designated speed by increasing the system bus, from a default For example, instead of a data rate of 133MHz, DDR memory transfers data at 266MHz.

or something was not compatible. Upgrade factory-direct today with Crucial Technology. Some memory questions Does it matter which slots I plug my new module in?

Supply and demand.

  • Memory is cheap enough nowadays that you're probably better off just buying some new DIMMs and calling it a day — that's the only way you're going to get the best
  • Upgrade Kits (special deals on 2 modules) 128Mb RIMM Upgrade Kit, Samsung (2x 64Mb modules), 184pins, PC800, 40ns, non-ECC Manufacturer: Samsung, Warranty: Lifetime. 256Mb RIMM Upgrade Kit, Samsung (2x
  • The ECS motherboard supports PC2700 DDR RAM, so if that is installed with the new processor, the effective data transfer rate would be increased from 200MHz to 266MHz, and the bottleneck

So, lastly, I put the continuity modules back in RIMMS 3 and 4 and put my new sticks of RAM in 1 and 2. RAM is probably the most critical system component. A Socket A motherboard must specifically support it. Rambus memory supports both ECC and non-ECC applications.

There is a good free system scanner from Crucial (google crucial memory scan). Click here. Occasional changes in market demands will alter inventories and, therefore, raise or lower prices. Also, he did say old PC.
