Can You Mix 133mHz RAM With 100mHz?

Before we show you how to distinguish PC133 memory from all others, some background information might be appropriate. We have broken it down based upon Samsung's reference sheets: 1 2 3 4 5 6 7 8 9 10 11 12 13 KM 4 8 S 8 0 3 0 Pick and Place machines are programmed to know which chips are placed where. If in doubt, set your RAM to run at 100MHz with 3-3-3 latency (CAS3), if your BIOS gives you that option, that will force it to run at a conservative PC100

Below are some of the terms you may see in those descriptions. By varying the total number of PCBs in each array based on size, Micron maximizes the number of modules made from a given amount of raw materials. It's working fine, and with the new 512 in it, it's working fine. Triple6, Dec 7, 2004 #5 rodeognome Thread Starter Joined: Dec 13, 2003 Messages: 1,360 thanks for those savvy answers guys and gals.

That modulemight not work in your computer if the controller won't adapt to 2-bytewide access from each chip.Also, although I have not used low-profile PC-100/133 modules, they doexist. Other vendors in the upgrade market simply buy the modules from a manufacturer, repackage them, and sell them under their brand name. Functional and nonfunctional chips are identified and mapped into a computer data file. He has been a contributing author on a number of titles for Sybex, most recently the best-selling A+ Complete Study Guide, Second Edition.

  • These basic steps are repeated for additional layers of polysilicon, glass, and aluminum.

  • However, at the low cost of ram you could easily replace one slower stick with a new 133 one.

Many modules also undergo additional inspections using automated X-Ray equipment to ensure no unreliable solder joints exist. Does this meanit> won't run PC133 RAM, and can I mix 133 & 100 RAM on this board?>> Who has experience doing this on their boards? For example, if your computer has a maximum memory capacity of 2048MB (i.e. 2GB), and has two slots, the largest module you can install in each slot is a 1GB memory This site is completely free -- paid for by advertisers and donations.

In theory, as long as manufacturers meet or exceed these specifications, all memory modules produced by all manufacturers will be identical and rarely produce problems. While there are many cases where PC100 modules, and even the older PC66 SDRAM modules, have worked together on the same motherboard at 133MHz bus speeds, however those situations are extremely They will not function and will not even fit in the same sockets. these days *almost* all memorycan run at 133MHz anyway, the primary reason new memory modules are beinglabeled as "PC100" is due to this density compatibility issue with olderboards/chipsets like the 693.

In other words, the first data item transferred in a Rambus transaction takes longer to initiate than the first data item moved in a DDR system. As you can see from the red arrow, this Micron chip has a "-8" designation that identifies it as 100MHz bus and 10 nanosecond.

The heat melts, or reflows, the solder into a liquid stage. Rambus die (chips) are much larger than SDRAM or DDR die. At present, one of the overall limiting factors in PC systems today is the bus speed. The textbookdefinition of density is not the focus here, however he used the termcorrectly.M.

Thread Status: Not open for further replies.

By the end, while I finalized on what RAM I need for my notebook, I had compiled a small document on Basic RAM Information courtesy Crucial® FAQs.  I hope this guide to be helpful PCBs are built in arrays, or sheets, made up of several identical boards. After the contact windows are etched, the entire wafer is covered with a thin layer of aluminum in a sputtering chamber. While performance gains from dual-channel chipsets aren't huge, they can increase bandwidth by as much as 10 percent.

Kingston Technology uses a similar method to indicate the parameters and specifications of their memory modules, and this link will take you to the Kingston Technology Reference. All the rest are8-bit x 4 bank whereas the 128MB module is 16-bit x 4 bank. The ram only responds to the computer not the other ram.

Many newer computers use double data rate or "quad-pumped" front side busses.

PC100 RAM is in short supply & mostly used RAM. While Rambus modules may have the ability to transfer data faster, it appears to have higher latency (the amount of time you have to wait until data flows) than that of The Server+ exam certifies the knowledge of mid- to upper-level technicians with 18-24 months of strong IT experience using hardware functionality, including server installation, troubleshooting, support, and second level support. This common uniformity standard was designed to insure that all SDRAM memory module should be created equal and there shouldn’t be any major variations between any two module made by different

To do this, the chips are mounted to printed circuit boards (PCBs). What do you mean by that? solved is it ok to mix these ram sticks together? However, be very careful to order two modules with the exact same specifications; the modules must be identical to each other to perform correctly.   How much RAM can Windows handle?

The surface tension of the molten solder prevents the chips from misaligning during this process. When the module design is perfected and the PCBs produced, memory module assembly begins! Typically, the 133 MHz SDRAM chip has a speed rating of 7.5 nanoseconds (7.5 billionths of a second) when running on a motherboard with a 133 MHz Front Side Bus. These checks provide immediate feedback to ensure continuous improvement.   Memory Module Manufacturing Part 5 The first step in assembling the memory module is Screen Print.

There are also times when a system would only accept a 512MB module at launch, but down the road would take a 1GB module with a BIOS upgrade. Please type your message and try again. Of course PC100 costs more, but that's agiven since it takes twice as many chips. Frequently Asked Questions About Memory Troubleshooting Memory Problems Megabyte (MB) vs.

The "2100" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 2.1 GB. In 1997 we saw SDRAM speeds jump to 66MHz with the release of PC66 SDRAM, and shortly thereafter the engineers moved the speed lever again, this time to 100MHz with the Micron is the memory supplier to the top PC manufacturers in the world. Beware!

Some PC-100 DIMMs have chips with a 10ns speed, which you definitely wouldn't want to use on a 133 MHz bus. Will the MoBo accept the mix?

And no matter what type of memory you use, more is typically better.

The terminology "dual-channel memory" is being misused by some in the memory industry, which can mislead the consumer. Also, you should buy double-sided RAM, not single-sided, as if it's old enough to use PC100 it probably won't recognise single-sided properly (i.e. Some older ones required thatyou use the same density within a bank (i.e., within a pair of slots).You have to check what the maximum module size that the motherboard canhandle in Most likely purchasers buying new RAM for a PC100 application, will get PC133 RAM from the supplier.Thus, stick with your current total of 768MB. Cheers, Tom Feb 21, 2007 5:23 PM

All the chips are placed on a PCB in just a few seconds! Well my old Emachines can max out at an unofficial 512 meg. In this case TSOP II (400mil) 11 - No value 12 G = Indicates Power - Auto & Self-Refresh (3.3V) 13 8 = Indicates Min. Memory chips are integrated circuits with various components (transistors, resistors, and capacitors) formed on the same chip.
