Adjusting RAM performance after installing additional modules
Adjusting RAM performance after installing additional modules
hello, you just bought 8 gigabytes of RAM from the same brand and speed as your other two sticks. before that, you had 16 gigabytes of 2666mhz RAM in dual-channel mode (four slots total). now the two new sticks are installed in the dual channel slots, which is the GIGABYTE H370 HD3. you're having trouble overclocking them to 2666mhz and they're stuck at base speed. your PC crashes when you try to use the XMP profile. the RAM you have is Corsair LPX 8GB DRAM 2666MHz C16, with two sticks of 8GB and two sticks of 4GB. anyone can assist?
Typically combining various RAM types and sizes isn't recommended. Stabilizing four sticks over two channels is also quite challenging. The main advice I can offer is to match the timings to the manufacturer's specifications and increase the voltage, though other options are limited. Running a command rate of 2 can sometimes assist. Otherwise, you might consider using the two 4GB sticks together with XMP enabled, operating at the default 2133MHz across all four, testing XMP at a slower speed like 2400MHz, or opting for the same kit with identical capacity next time.
You have four 4 GB SD cards in a 4 DIMM setup. Wouldn't it be better to buy two 8 GB cards instead? A higher speed option would make more sense. As @TwilightRavens pointed out, installing four modules at once is tough.
