Checking DDR3 1600MHz and 1333MHz RAM compatibility, along with assistance for minidump files and BSOD issues.
Checking DDR3 1600MHz and 1333MHz RAM compatibility, along with assistance for minidump files and BSOD issues.
I possess the following setup details
Intel core i7 4770
Gigabyte H87-HD3
Gigabyte GTX750
Windows 11 24H2
At first, I had a Kingston KHX1600C10D3/8G (16GB total) without any BSOD or other issues. RAM operated at 1600MHz. Later, I acquired another pair of Patriot PV316G160C9K (2x8GB) and several BBSODsSOD appeared, particularly after turning on the PC.
After performing Memtest86+, I detected an issue with the Patriot RAM modules. Since these were the latest models I had, I replaced them with a set of G.Skill F3-12800CL10-8GBXL.
G.Skill modules are marketed at 1600MHz and match the timing of the Kingston units. Yet after installation, their speed decreased to 1333MHz. I concluded the problem stemmed from these new sticks, as even using them alone maintained the same speed.
XMP was turned off because Kingston RAM did not support it. I opted to manually adjust the settings, aligning both the speed and timing with the advertised values.
My concern is why G.Skill sticks perform at a lower rate. If I fine-tune them slightly—raising the speed and keeping the timing consistent—I wonder if that would resolve the issue without risking damage.
I know 1600MHz fits within the JEDEC 1333MHz OC profile, but I assumed it would be selected automatically. All RAM models are listed in Gigabyte’s supported range.
Still, another BSOD occurred. Someone could assist with the minidump?

I bet you only looked at the first three Primary timings (10-10-10). Did you compare the Seconday and Tertiary timings too? There's a whole bunch of additional SPD timings accessible in the BIOS, some of which are displayed in Aida64. https://www.aida64.com/downloads It's unlikely all the Primary, Seconday and Tertiary timings will be the same on the three different kits you tried. In other words, they're mismatched. Similarly, the physical memory chips on each set of DIMMs will probably not be identical and may be from different manufacturers. You can check the chip type with Thaiphoon Burner. In the example below, the chips are from Micron Technology. https://thaiphoon-burner-official.com/ Even if you fit two "indentical" pairs of DIMMs from the same manufacturer with exactly the same part number, the memory chips will most likely be from different "bins", with subtly different characteristics when overclocked. That's why it's recommended to buy a single kit of 4 DIMMs (not 2 different kits) so you know they'll be matched, with a better chance of stability. In any case, installing 4 DIMMs usually places more strain on the CPU's Integrated Memory Controller channels, making overclocking more difficult. If a manufacturer states their kit of 2 DIMMs can run at 1600MT/s, it doesn't mean that 4 DIMMs will run as fast. More loading on the CPU IMCs equates to potentially slower speeds. Motherboard manufacturers sometimes specify lower XMP speeds when you fit 4 DIMMs instead of 2, especially on DDR5 systems. Apart from benchmarks, the difference between 1333MT/s and 1600MT/s is often marginal in real world apps. Most of my DDR3 systems are running at 1333 or 1600 (depending on the maximum XMP speed). I have one system at 1866 and another at 2133, but both have only 2 DIMMs per mobo. https://forums. It's better to run a stable system at 1333MT/s, even if you have to sacrifice a few FPS in a game, than put up with system crashes at 1600MT/s. If you need more speed, consider a modern DDR5 system where 6000MT/s is the norm on AMD and 6600MT/s on Intel. The BIOS may have spotted 4 DIMMs and automatically reduced the memory clock speed from 800MHz (1600MT/s) to 666MHz (1333MT/s) to maintain stability. https://www.kingston.com/datasheets/KHX1...3B1_8G.pdf The Kingston memory does support XMP (1600MT/s). As I suggested above, the BIOS may have reduced memory speed from 1600 to 1333MT/s for greater stability with 4 DIMMs. XMP ratings are not an automatic guarantee of success in all circumstances, especially when using 4 DIMMs or mismatched pairs. Life's like that.
I managed to fixed the timings as you told me and dropped the speed to 1333MHz (auto). I can't find a 4 stick set here so I have to stick with this configuration. Also, I don't play games, only office work, but I need 32GB RAM. However, I still get random BSOD after waking up the PC from sleep. I'm still investigating the issue.
