CPU / RAM overclocking
CPU / RAM overclocking
I just completed assembling my new PC. I frequently encountered BSOS during unusual moments while performing light tasks such as browsing the web. However, I only experienced these issues when using Mozilla, not Internet Explorer 11. When rendering videos, RealTemp displayed high load percentages (90-92%), and the rendering jobs lasted between 17 to 22 minutes. I never faced the first BSOD. Whenever it occurred, the screen remained visible long enough for me to read the message, but the main title indicated a "MEMORY MANAGEMENT ISSUE."
I turned off Turbo Boost on both levels (my motherboard supports two levels), but the BSOS persisted, especially during light tasks. I chose the Corsair 2800 chipset, which is compatible with my CPU (non-ECC) and is suitable for a 2133 MHz memory. The maximum memory size depends on the type: 64 GB is recommended.
Memory specifications:
- DDR4 1333/1600/2133
- Up to 4 memory channels
- Bandwidth up to 68 GB/s
- No ECC support
The BSOS ceased when I disabled XMP and set the RAM to "jedec 2133." Any suggestions for increasing the memory capacity?
I have optimized the CPU to a stable 4.0 core, with temperatures staying between low to mid 50°C during full load (using Prime95 v26.6). The optimization process involved using XTU, running benchmarks, and uploading results to HWBOT online. I compared these settings with others having the same CPU and chipset, downloading compatible configurations.
Are there any other recommendations, or have I reached the limit of 2133?
I should have noted two things—BSODs appeared before I overclocked at the standard speed of 3.2. I even turned off Turbo Boost since it’s Turbo Boost 3.0, and Intel mentioned my CPU only supports Turbo Boost 2.0, which might have been the reason, but unfortunately not. The BSODs kept happening until I reset the RAM speed back to 2133.
And now you mention it, when a BSOD would occur, I’d notice two sticks missing from the BIOS—my BIOS would list 48 GB with two slots, C1 and C2 marked as not populated or unavailable (I don’t remember the exact wording).
I bought RAM in packs of four sticks each. When installing, one pack was placed in all A1, B1, C1, and D1 slots, and I color-marked them to avoid confusion with other packs. The second pack went into the “2” slots, which is unusual since I’d find two neighboring sticks from different packs both showing issues. After re-seating everything, I noticed this problem 3 times, and each time I would flash the latest BIOS, bringing the issue back but restoring full 64 GB in the BIOS.
CorsairSSC :
The memory speed list doesn't match DDR4, it's more like DDR3. I understand it's annoying to ask but are you using the correct RAM?
You can't actually fit a DDR3 stick into a DDR4 slot (or vice versa). That shouldn't be the problem.
I bought my RAM in sets of four sticks each, and when installing them, one set went into all the A1, B1, C1 & D1 slots and I labeled them clearly to avoid confusion with other sets.
It's usually best to purchase all your RAM together as a single kit, since mixing separate kits isn't guaranteed to work, even if they're from the same brand/model. I can't confirm for sure, but I suspect the issue might be related to mixing RAM kits. You might be able to get them to function by adjusting timings and voltage manually.
the issue has been present or existed when I purchased these items. No one provided 64 GB packs that were available in the QVL for my board. I would have liked to choose 16 GB sticks instead, which only recently became accessible. However, this was the reason I kept all the sticks from one pack in the "1" slots and the second pack in the "2" slots. If it's incompatible RAM, why does it only happen on two RAM sticks from different packs in neighboring slots, C1 & C2? Still, it gives me a clue—maybe I should move those sticks to other slots and check if the problem persists there. The adjustment of the RAM speed to what Intel claims supports (2133) hasn't resolved the matter yet.
didn't wish to disturb a friend, a former Microsoft engineer, but I just spoke with him about this topic. The first advice he gave was to take out the four sticks in the secondary slots (A2, B2 etc.) and check if I could run them up to 2800 without BSODs. He suggested marking each stick removed so I would remember which slot it came from before taking it out. Then, with only 32GB of RAM installed, increase the clock speed and see if the BSODs reappear. If they don't, it could be a faulty RAM stick in the second group or a compatibility issue. The reason for marking the secondary sticks beforehand was to ensure I didn't put the same stick in the C2 slot when reinstalling. If removing the BSODs with one set of RAM in the main slots, I should take out those sticks and try using only the secondary ones—this might point to a defective stick from the first group causing the problems.
