PCChips M848A ram speed question
My old board died and I replaced it with a PCChips M848A - changed
nothing else. The problem is that the ram speed is autodetecting 166 and not the 333 that I had with the previous board. Can I set this higher without doing harm? If so how? Thanks in advance for any help. This is my first motherboard replacement. Phil |

The one showing "333" is DDR333 or dual data rate 333. That is a measure of the number of million transfers per second. There are two transfers per clock cycle, for dual data rate memory. The "166" refers to the clock rate in megahertz. There are 166 million clock cycles per second. The two numbers, in fact, mean the same thing. Both memories are running at the *same* speed. It is just the units of measure that are different. - Clock Period - _______ _ _/ \_______/ Clock 166 million _______ _______ _/ 1 \/ 2 \_ Two data values per clock \_______/\_______/ DDR 333 million The best thing to do, is compare systems using the same Windows utility. A program like CPUZ for example (cpuid.com). That is what overclockers use to verify their BIOS settings, from the convenience of the Windows desktop. HTH, Paul |
