Issues with RAM performance and stability
Issues with RAM performance and stability
Your system is showing a lower memory speed than expected because the RAM is being accessed at 2666MHz, but your PC is interpreting it as 1333MHz. This can happen due to driver settings or BIOS configuration. Check your BIOS options for RAM speed settings and ensure they match the actual speed of your memory. If needed, update your drivers or adjust the memory settings accordingly.
ddr(number) refers to double data rate random access memory, meaning it operates at twice the clock frequency, resulting in 2666 MHz. The timing appears quite relaxed, with a pattern of 19-19-19-43. For Hyixin chips, consider tighter timings such as 5-15-15-35 or 16-16-16-36.
That matches what you see in Task Manager, whereas HWinfo displays the speed without accounting for double data rate.
^^^ btw this is a jedec 2666c19, model number tells rank config and ic, hma81gu6cjr8n 8gbit hynix cjr single rank (8gb single sided cjr stick) should do 3800-4000 with relative ease but depends on your mobo and cpu wether or not you can actually hit those speeds cause im suspecting a crappy oem board which wouldnt allow ram oc nor timing adjustment Spoiler heres what cpuz shows at 3400 ddr3 for me so yeah perfectly normal, dunno how to get advertised speed to show in windows though since i have to use setfsb to get this thing from 3312 -> 3400 in windows since it will not bios boot 3400 1700 is real speed and 3400 is effective or advertised speed cause ddr
