Memory settings cannot be altered on dp55wb.
I was attempting to boost the performance of my i5 750 using my dp55wb motherboard, installing a new 8GB RAM module with 1600MHz speed. I believed the upgrade would be straightforward, as I had successfully achieved 3.7 GHz with my previous 2GB modules at 1333MHz. I installed the new RAM and everything functioned normally at default settings. When moving to overclocking, I left the memory settings unchanged and switched it to automatic mode to adjust the multiplier to 8, aiming for a 180MHz clock speed and a 3.6GHz CPU frequency. Initially, I only adjusted the memory settings to manual and rebooted, but this resulted in a memory error beep. After another reboot, I experimented with different approaches, but the system still failed to boot properly with manual memory settings. Eventually, I tried overclocking in automatic mode, which worked better, but the BCLK could only be increased to 150 before the BIOS began exceeding 1800MHz, causing instability. I suspected a hardware issue and replaced the 8GB stick with an older 2GB module, which also failed to resolve the problem. Even without modifications, leaving manual memory tuning enabled still prevented the system from booting correctly with both sticks. I’m unsure what to do next.
DDR memory refers to Double Data Rate technology. This approach doubles the performance by employing two communication paths between the RAM and the memory controller, either integrated into the chipset or directly within the processor, which is common in modern CPUs. The term "double" indicates simultaneous reading of both memory channels. The actual clock speed would be 667MHz, but using both channels makes it functionally equivalent to a 1333 MHz RAM setup. When only one channel is available, the system operates as interleaved RAM rather than DDR. Combining various RAM sizes and speeds can achieve similar results since the parameters don't support full DDR operation. To resolve your issue, turn off the machine, install the desired RAM, reset the BIOS by removing or using the backup battery/jumper, reinstall the components, power it up, and reboot.

The topic you're referring to involves DDR memory. DDR stands for Double Data Rate. It achieves the "double" by employing two channels between the RAM and the memory controller, whether integrated into the chipset or built directly into the processor, which is common in most recent CPUs. This "double" capability allows it to read both memory sticks simultaneously. The actual clock speed would be 667MHz, but using both channels makes it functionally equivalent to having 1333 MHz RAM. If you only have one stick, it operates with a single channel, switching from DDR to interleaved RAM. Combining different RAM sizes or speeds often results in the same performance since the parameters don't support DDR operation. To resolve your issue, turn off the machine, install the desired RAM, reset the BIOS by removing or using the backup battery and/or jumper, reinstall the battery/jumper, power up, and reboot. More details: http://www.hardwaresecrets.com/everythin...ectures/2/ Remember, you're not using two sticks, so the explanation might seem unclear. My BIOS shows effective speeds instead of predefined ones. ddr. Also, I can run my PC stably at default settings, but changing memory attributes prevents booting and requires a CMOS reset. I'm just trying to fix this problem.
