Design speed not met by Ram model
Design speed not met by Ram model
I'm facing issues with my older system (Asus A7V8X-X). I recently added a Kingston DDR kvr400x64c3a/512 setup, which is meant for 400MHz. Running at full CPU speed without adjusting the RAM to that frequency is causing problems—both the RAM doesn't work properly and the PC shuts down. Anyone have experience with this situation?
Basic idea – your board is different, the chip you have isn’t the same, and not every Socket A chip supports 200MHz on the bus. Which CPU are you running? And does the 512MB of RAM refer to one stick or both sticks together?
I experienced many Via chipsets over the years. Regarding your RAM issue, it seems the problem lies with the lower speed rather than compatibility. It’s likely related to the FSB speed and your processor model. Based on the user guide, if your CPU supports 200 or 266 MHz FSB, you can use 400 MHz RAM. With a 333 MHz FSB setting, the RAM will reach 333 MHz. The board is compatible with 200/266/333 MHz speeds. Kingston’s naming style indicates /512 at the end of the model number equals 512 MB per stick, which I accept as accurate. This detail is important.
Remember I mentioned the chip, not the board. You're right about its capabilities. Any Asus board from that series should work with it, even if it's a VIA model. Keep in mind that FSB matters—it influences how RAM speeds actually show up when the system starts. It's interesting how many 133 chips (like the XP-M Barton core mobiles) can handle 200 on the bus without issues, just like standard 200 chips (E code). Those should meet their specifications, though most 166 chips (D code) struggle to reach or exceed that. You might try a tool like SetFSB to push it past 200FSB in the OS, but it's unlikely to boot at full speed. I'm aware of clockGen support only for Nvidia chipsets; nothing VIA seems to work with it, though SpeedFan probably supports both types. I had to double-check their labeling because they listed something like kvr400x64c3a/512, and yes—there are also 256MB DDR modules available (totaling 512MB). That's a couple of sets, including some BH5 sticks. It's been a while, and my personal RAM (CRS) isn't performing the way it used to, which was a concern back then.
