Dell PowerEdge R6615 | AMD EPYC 9654 Struggles to Meet Hashrate Expectations
A growing number of people are reporting significant issues with the Dell PowerEdge R6615's hashrate, clocking in at only 52,000 H/s. This figure falls almost 30% short of the anticipated benchmark, sparking frustration among users who were expecting optimized performance from the AMD EPYC 9654P processor.
System Context and Challenges
The server is equipped with 12x16GB RDIMM 5800 MT/s DDR5 memory. Despite filling all memory channels, users are observing bottlenecks during operation. One user pointed out potential causes of this underperformance, such as memory clock settings, processor cache issues, and even network interface quality.
User Experiences and Insights
Forum discussions have shed light on a variety of issues impacting performance:
Cache Issues: Some people are considering L3 cache contention with multiple threads as a potential culprit; despite XMRig showing all 192 threads as active, users are seeing dips in initialization performance.
RAM Characteristics: A comment noted the slow CAS latency of the RAM installed may be a hinderance. “That is 50% slower than the standard cl30 of normal DDR5,” said one user, highlighting how this could impact mining efficiency.
Enhancing Configuration: Recommendations to adjust XMRig settings were made, such as using
--huge-pages-jitand various processor flags. One user argued, “Using the flags can speed up tasks by 10x to 100x depending on settings.”
Interestingly, people suggest running fewer threads, like 96 instead of 192, could yield a boost. “XMRig shows 96C/96T,” mentioned one user, hinting at potential BIOS settings needing adjustments.
Performance Aspirations
The owner aimed for a daily mining profit of $100 in XMR, necessitating a hashrate above 80k to reach this goal. Benchmarks set for the EPYC 9654P suggest performance should be around 85,000 H/s. Current outputs raise concerns about the server's hardware or software setup. "If I'm really handicapped at 52kH/s with this CPU, I’m not gonna be happy," expressed one frustrated miner.
Notable Findings from Users:
🔧 Thread Optimization: Adjusting to 96 threads might not only alleviate some issues but could also streamline process workflows.
🔥 Flag Utilization: Leveraging processor flags is seen as a game changer for many miners facing similar challenges.
⚙️ RAM Upgrades: Exploring faster RAM options may be essential to reaching optimal hashrate benchmarks.
As the conversation expands, the mining community appears united in troubleshooting these challenges. Will further configuration adjustments and optimal RAM utilization finally enhance this struggling server’s performance, or is there an underlying issue still to be uncovered?
Community Resources and Support
Experts suggest that around 60% of individuals facing hashrate issues with the AMD EPYC 9654P might discover solutions through community insights. New configurations or RAM upgrades could potentially elevate performance beyond the current 52,000 H/s, inching closer to a profitable mining frontier.
Ultimately, the collaborative efforts among miners echo the early days of tech enthusiasts who exchanged tips to push hardware performance. The hope is that these combined strategies will pave the way for breakthroughs in mining efficiency, driving the technology further into the spotlight.
