Is It Bad To Use PC100 Memory On A PC133 Memory Slot ?

That's because the overall system performance is affected by other bottlenecks at the hard drive, video card and other peripherals. Refresh is the ROOT cause of most DIMM incompatibility.

Normally the five red arrows that you see above would not be present when you review a data sheet. Most older machines have the ability to autosense or manually choose a setting of 100 or 133 in the BIOS. Before we show you how to distinguish PC133 memory from all others, some background information might be appropriate. Yes, my password is: Forgot your password?

Non-parity memory is the norm for home computer use. Here are two examples, a PC100 module from Micron and a PC100 chip from Samsung. by Earth9111 / August 29, 2005 11:10 PM PDT In reply to: Memory, difference between PC100 and PC133 What is PC100, PC133, PC1600, PC2100, PC2700, and PC3200 memory?

PC133 should work with PC100. I am currently successfully using a PNY PC133 256Mb DIMM (I was given for free) in my old Abit BH6 motherboard, 866Mhz PIII computer. If you look closely at each of the five part numbers, you will see that the only difference are the last two digits. Join our site today to ask your question.

If you plug a newer PC133 DIMM into an older machine that was designed for PC100 memory, because it is being refreshed for only half (or one quarter) the required number Unfortunately though, in the real world, you will find that SDRAM modules with identical SDRAM chips, can sometimes reach entirely different frequencies for no other reason than differences in the manufacturing Useful Searches Recent Posts Menu Forums Forums Quick Links Search Forums Recent Posts Menu Log in Sign up AnandTech Forums: Technology, Hardware, Software, and Deals Home Forums > Hardware and Technology This will tell you immediately if the memory will work in your system or not.

Memory tends to be one of the more troublesome performance bottlenecks in the computer, so the small extra cost for the faster memory is worthwhile. When manufactured, PC133 SDRAM, must meet Intel's requirements (the PC133 Standard) for use with motherboards having a 133MHz FSB (front side bus). This yields bad data reads from memory and the motherboard refuses to work with that DIMM if the motherboard is not set up to work with it. Politics?

Thank you for helping us maintain CNET's great community. There are compatiblity issues with newer PC133 memory and older PC100 RAM slots. 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 http://htmltemplatesfree.net/is-it/is-it-necessary-to-remove-agp-card-before-adding-memory-module.html Politics?

The numbers identify the FSB speed of the RAM.# For SDRAM PC100 memory runs at a FSB speed of 100MHz# PC133 memory runs at a FSB speed of 133MHzFor DDR,# PC1600 As I mentioned in Addendum #1, some RAM manufacturers already publish this information and it appears on their retail packages.

Sorry, there was a problem flagging this post.

I believe I read somwhere that with a PC 100 card in it, it will only allow the other PC 133 cards to run at 100 mHz; only as fast as The problem is we can’t see inside the chips so, asking the manufacturers is the only way to be sure. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended. However, PC100 cannot operate at 133MHz speeds.

It's working fine, and with the new 512 in it, it's working fine. Also the number of chips on the module, such as (16X8) What would happen is that if you manage to get to windows without a blue screen...then your good.
