| 484837 | 2006-09-15 02:13:00 | Could someone clarify how the relationship between FSB and the speed the memory runs at comes about please? I have put together a new system using a Gigabyte GA-M51GM motherboard, an AMD X2 3800+ CPU and 1GB of PC6400 DDR2 memory. The BIOS reports a memory speed of 667Mhz. I've done some reading of various articles on the web, but I'm still confused about how the 667Mhz comes about, from a 200Mhz? FSB. What started me thinking about it is that I notice the memory is supposed to be run on 2.1volts, but my motherboard is set to 1.8volts, and can't be changed. Does this really matter? The above setup seems to be running fine and Memtest86 reports no errors. Thanks. |

| 484838 | 2006-09-15 02:32:00 | The memory manufacturer will test samples in each batch, and say the memory will run at its rated speed at a particular voltage. If you run it at a lower voltage, it will not be guaranteed to run at the rated speed. If you don't get any strange error messages from the OS or applications, memtest 86 doesn't complain, it's not being overclocked to the point of causing errors. ;) As the weather warms up, keep an eye on it. | Graham L (2) | ||
| 484839 | 2006-09-15 04:26:00 | 2.1v is pretty high for DDR2, one of the main selling points besides fasters speeds of DDR2 is its low power usage. 1.8v is the correct voltage for DDR2. I remember the good ole days when you could run Winbond BH-5 at 3.0v :eek: | Pete O'Neil (6584) | ||
| 484840 | 2006-09-16 00:11:00 | Thanks for the comments. Nothing seems broken in the memory department at present, so all is well, I'll assume. | rumpty (2863) | ||
