Overclocking my RAM
Overclocking my RAM
Hi guys, I understand you're not too concerned about the performance gain from overclocking RAM. What matters most is getting the best performance that lasts for a long time. I increased my RAM speed to 2800mhz from 2133mhz. If I push it even higher, Prime95 reports hardware failure. My question is whether I need to adjust the voltage. I raised it by about 0.025 volts, not because it was unstable, but because I assumed it wouldn't be.
memtest86+ is free software. It is considered the best tool for checking RAM.
You can find it at: http://www.memtest.org/
It works without an operating system and starts from a USB drive, DVD, or floppy disk.
By comparing speed to latency, you typically get around 140, which matches your current setup—no real improvement.
Some applications may perform better or worse depending on the situation.
If you test one application at a time, create your own benchmark.

2800 speed ram offers advantages over binned RAM that can be boosted to faster speeds by adjusting voltage, usually up to 1.35v. Run tests with memtest86+; aim for multiple error-free passes. Success indicates suitability for long-term use. Your current standard is 2133 speed with a 15-pin case. As speed increases, higher CAS numbers may offset gains. A key metric is speed divided by latency—ideally around 142 for optimal performance. What latency does this configuration achieve?
Geofelt suggests that a higher speed RAM with a voltage boost can improve performance, usually up to 1.35v. It recommends testing with memtest86+ and performing several passes without errors. A speed of 2133 with a 15 cas is considered good, but increasing speed may also raise the cas number, reducing gains. One measure is speed divided by latency—142 is ideal. Your current latency at 2800 is around 20 clocks, which equals 140 when divided. This indicates your RAM is still functioning well, not worse than before.
