Overclocking Ram for a beginner's project
Overclocking Ram for a beginner's project
In short, I used a single stick Adata Gammix d30 with 16GB DDR4 RAM. I can't buy another 16GB DDR4 unit because of budget limits and because the deepcool assassin 3 would cause issues with the side panel when using a D30 height. I opted for Corsair Vengeance LX 8GB with 3200MHz RAM and the Adata Gammix XPG D30 16GB with 3200MHz. I understand they'll run in flexible mode, so up to 16GB will use dual channels and the remaining 8GB in single channel. It works fine for me. After adding the second stick, my game performance improved noticeably, though the RAM speeds differ. There seems to be a timing mismatch between my Corsair Vengeance LX and the Adata XPG Gammix D30. I’m very new to this stuff and don’t have much experience with RAM overclocking—just know that timing matters.
Ram overclocking is VERY time consuming (I am talking weeks of testing) also there is no guarantee that both chips can run at same timings. In your case I personally wouldnt bother trying to set timings or overclocking but if you want to there is only guide you can follow: https://github.com/integralfx/MemTestHel...guide/DDR4 OC Guide.md
The performance gap between those configurations is notable. The older specs suggest a larger variance, while the newer details point to a more consistent but slightly lower benchmark. The Corsair Vengeance LX 8GB at 3200MHz RAM advertises speeds around 18-18-36, but the actual results seem to hover near 22-23-24-16.
It’s set to 16-20-20-38, which isn’t matching the numbers listed above. The memory section displays the present clock speeds and RAM performance across all modules. The SPD overview indicates the default settings for each channel. Also, understood. Adjusting RAM speed isn’t straightforward, with plenty of potential mistakes… just a joke. Identifying RAM problems is tricky, and it rarely points to the RAM itself causing the problem. Issues can range from odd crashes and glitches to complete data loss. Don’t attempt manual RAM overclocking unless you’re comfortable risking total data loss and have a week to fine-tune settings and verify behavior.
Based on what you've shared, it seems these are the SPD timings without XMP enabled. When XMP is turned on, the frequency and timing change. You're wondering if this matters or if the main issue lies with the memory tab. Also, you're curious about jdec versions and why there are four tabs for CAS latency—something I didn't understand. And why isn't Corsair running at those specific clock speeds?
The SPD chart outlines the default RAM speeds (JDEC values are standard, varying with speed and voltage, offering varied timings). The chart displays timing changes across different rates. Both sides of the chart indicate the XMP profile as 16-20-20-38 at 3200MHz and 1.35 volts. The memory section confirms the actual running speeds match these XMP settings, showing consistency between what’s reported and what’s happening. The JDEC rows show hypothetical performance without XMP, highlighting differences in timing based on frequency. All relevant details align here—XMP settings remain uniform and correct.

After reviewing several discussions and the link you provided, I’m not as sure I’m prepared for a ram OC yet. I was confident about increasing my Corsair vengeance to 1.40v with 18-22-22-42, aiming for 3666 and turning on DOCP. It seems my attempt to boost the 66 MT/s might not have worked, and the system didn’t start at 3800, so I reverted back.
