Motherboard: P43DE (BIOS Version P1.70)
CPU: Intel Q8400 Core 2 Quad 2.66GHz.
Memory: Kingston KHX8500D2k2/4G 5-5-5-15 2.2v (2 x 2 2GB sticks)
Graphics: NVIDIA GeForce 8400 GS
O/S: Windoes 7 64 Bit.
Hi All,
I bought the above board yesterday to replace my Gigabyte GA-EP35-DS3L board. The reason I rplaced the Gigabyte board was because I recently bought a kit of Kingston KHX8500D2K2/4G PC-8500 1066MHz memory and no matter how hard I tried I could not get it to run at 1066MHz. CPU-Z & System Information for Windows both reported it as being PC-6400 DDR2 800MHz and I had read some reports about the Gigabyte board having issues with running memory natively above 800MHz.
I replaced the board with the Asrock and installed the memory and at default BIOS settings CPU-Z & System Information for Windows still reported the memory as PC-6400 DDR2 800MHz 5-5-5-18 1.8v. I went into the BIOS and set the timings & voltage manually to what Kingston say is correct for 1066MHz which is 5-5-5-15 2.2v (Kingston datasheet) http://www.valueram.com/datasheets/KHX8500D2K2_4G.pdf
I also set the DRAM Frequency to 533MHz which is what Asrock state in the BIOS guide and even though CPU-Z & System Information for Windows still reported the memory as PC-6400 DDR2 800MHz, in the system summery in the BIOS it reported it as 533MHz DDR2 1066MHz. The only problem with those manual settings are BSOD with an error message dumping memory to disk, then the PC reboots. This has only happened whilst streaming video online. At default settings everything is fine. Also when I set everything manually CPU-Z shows the changes to the timings but still shows the voltage as 1.8v not 2.2v this happened with the Gigabyte board too.
Can anyone help me here? Has anyone managed to get this memory running at 1066Mhz? After all it is meant to be PC-8500 1066MHz memory not PC-640 800MHz which can be overclocked to 1066MHz.
By the way I have ran Memtest86 and it reported no errors.
