Issues with DDR3 ram overclocking and related queries
Hello,
At the start I would like to express my gratitude for your understanding of English (I’m from Poland) and your assistance. I’m a beginner in overclocking and not everything is clear yet, so your support will be invaluable.
My current setup is: i5-4690k @4.5GHz & SPC Fortis 3 | Msi Z97 Gaming 3 | Palit 1070 Super JetStream @ 2063/4400mhz | 16GB (2x 8GB) Crucial Ballistix Sport 1600mhz CL9 | CoolerMaster G550M | WD Blue 1TB & Samsung 840 series 128GB | Phanteks P400S Tempered Glass
I overclocked my RAM about six months ago and it reached 2400mhz with a CR2 BIOS version 1.76V, 10-12-12-31. However, yesterday my PC crashed while playing CS GO (I didn’t play that game, so that was the reason for the long downtime). I decided to fix the issue and began from scratch – installing SuperPi 1.9, AIDA64, performing memory tests, and running memtest86 7.5. Among these steps, I encountered errors even with the default BIOS settings (even for a CPU), so I switched to version 4.3 – a non-UFE release.
Currently, I’m testing:
- Default RAM configurations
- 1866mhz 10-10-10-27 CR2 1.55V with VSA 0.9V, both VTT at 1.1V (parameters unchanged from previous run – it worked without issues)
- 2000mhz 10-10-10-27 CR2 1.6V
- 2133mhz 11-11-11-29 CR2 1.65V
- 2400mhz 10-12-12-31 CR2 1.7V (many bugs in memtest86, even at higher voltage – increased VTT to 1.15 and VSA to 0.92V)
I’ve only listed the working configurations so far (no BSOD during boot or reset settings in BIOS). Now I’m running 2133mhz 9-11-11-31 CR2 1.68V (actual 1.668), and memtest86 passed for about 35 minutes without errors. My goal is to achieve the best possible performance from that point.
I’m still trying to figure out the timing rules (for example, if the last parameter increases by 1, the next should be +3) and ensuring the voltage settings don’t cause damage (the last overclock used 1.76V on DRAM in auto mode with VTT at 1.76V). I really appreciate your help!
4th timing should equal the sum of the first three.
1st timing is the most critical; lowering it increases RAM speed.
2nd timing must match or exceed the first.

Bottom line—overclocking RAM offers minimal performance boost.
Consider it only if you have an onboard GPU. Otherwise, it risks damaging the RAM.

The fourth timing should equal the sum of the first three. The first timing is the most critical; lowering it increases the RAM's response speed. The second timing must match or exceed the first. Complete guide available at the provided link. In short, overclocking RAM offers minimal performance improvement. It’s best suited only for systems with an onboard GPU. Otherwise, it risks damaging the RAM. Thank you for the helpful and detailed information. I noticed a noticeable difference in browsing across more than 20 tabs after overclocking, which is important for me.
