Overclocking:


Our overclocking session with the XPG Spectrix D40 3200MHz RAM went pretty smooth. Our overclocking journey begins by increasing the DRAM voltage up to 1.37v for a starter, then we kept pushing the multiplier with timings on auto until the system became unstable. Then we dropped down a notch to find a stable overclock. And we landed on 3600Mhz with 12-21-21-43 timings on auto.

We then started tightening the timing at 3600Mhz and we finally landed on a stable overclock of 3600Mhz at 17-19-19-36 timings. All while the VCCIO and VCCST were set to auto. The stability was tested with a combination of Mem86+ test, Aida64 Extreme stress test, and Prime95 Blend test. All while the VCCIO and VCCST were set to auto.

So how much performance increase did we get with that extra 400MHz? Let’s find out below:


In Aida64 Extreme Cache & Memory Mark benchmark, we saw a good increase in the overall performance with about 5600MB/s increase in our write speed.


There was also an improvement of 1.5ns in the latency.


There was also an increase of 4cb in our Cinebench R15 test.


There wasn’t much of a difference in the overall firestrike test, but there’s an increase of about 111 points in the physics score.


Compared to the stock, we have an increase of about 162 points in single and 1157 points in multi-core performance. And the Spectrix D40 Oced also tops the chart.


There was also a good performance increase recorded in the PerformanceTest 9.0 Memory Mark threaded test.


In WinRAR benchmark, an increase of 400KB/s was recorded.


A good marginal performance increase in the Superposition performance.


As for gaming goes, nothing too noticeable. There’s about 2.25FPS increase in Rise of the Tomb Raider.


And not much has changed in the Thief Benchmark, other than the minimum FPS boost.
