Problem with RAM speed on ASRock P67 Extreme4.
Problem with RAM speed on ASRock P67 Extreme4.
Hello, I recently purchased the motherboard "P67 extreme4 from ASRock" for my main PC. My setup includes: CPU - i7 3779k, RAM - Adata 2x4 GB DDR3 at 1600MHz, and an SSD. Over time, I've observed my RAM speeds dropping to around 1300MHz despite attempts to raise them to 1600MHz. I've changed slots and replaced two RAM sticks, but the issue persists. Could you assist in resolving this?
Consider increasing bclk to around 105 and observe the effects. Bclk typically causes a full overclock of all components, including the CPU and RAM, so pushing it further isn't recommended unless you isolate it from other signals. You might reach about 105bclk, but higher speeds could be possible if you disable certain integrated devices. This isn't essential given the CPU's capabilities.
Bad guidance there. Initially you can't separate BCLK from anything until 1151 CPUs (I'm sure Haswell can't do it either). Secondly, you don't have to interfere with BCLK to get your RAM running at its rated speed. Plus, out of the four IV/SB CPUs I tested, only one actually reached 105MHz on BCLK, and high BCLK can lead to serious problems. RAM speed issues might stem from the motherboard failing to retain settings or from the board not being compatible with the RAM. OP, you shouldn't stress too much over 1333MHz versus 1600MHz.
There really isn't a straightforward solution, but the best approach seems to be connecting everything to an external frequency generator and carefully trimming traces. It's a tough task, really—what I'm saying is just a guess. The BCLK capability isn't limited to the integrated parts; it depends on more than just those chips. I assumed BCLK was about turning off certain components, but it actually involves more complex adjustments. I've already pushed my G31M S2C to 542 MHz with the E8400, so I expect to discover the maximum BCLK when the UD3P gets fixed.
The issue isn't about your phrasing—it's the data that's incorrect. You can't accomplish anything and won't be able to fix it. Overclocking the motherboard might allow disabling certain parts, but a low-end board won't support it. BCLK controls everything, which is why it's named BASECLOCK. PCIE, DRAM, CPU, DMI all matter.
