The memory settings were changed. The board with SOC on auto would operate at 1.08v, while Jedec under a fixed voltage would run at a different speed. That difference might be significant. Not sure about the numbers. Passive cooling works fine. This is what gives a PC its quiet performance. I tested my 2700X with 4GHz all threads (16 cores) at 1.188v during load, reaching around 16°C. This shows that keeping the chips cool greatly cuts down transistor leakage. Maybe adding a TEC would help.
The memory was stored on XMP, I accidentally missed out on the benefits! It's a mining rig so quiet matters little, it's already in the basement thanks to geothermal heat absorption. The temperature stays around 68-72°F (20-22°C) all year. I've run my 2700X at 4Ghz with a large air cooler, keeping the core at 85°C and using some optimized PBO. The extra 180W wasn't worth it for the marginal performance boost. At 3.7Ghz it draws about 90W and doesn't affect gameplay noticeably. Also, the heat in 85°C is concerning, so I'm cautious about long-term damage. I might upgrade to a 5800X when they have clearance sales, but I'm willing to pay $130 for this one if I can find a better deal on a cooler model. I used water cooling before, but I'm hesitant to rely on it for a PC that's not always nearby.
HWInfo helps keep your CPU from entering deeper low-power modes by regularly checking and updating its data. For better accuracy, consider using a clampmeter or multimeter to connect directly to the CPU's power lines and measure voltage and current at the VRM. The CPU uses around 30 watts (30-50 amps) spread across eight 78 amp MOSFETs, which means roughly 10-15% per MOSFET—lower efficiency. You could save a few watts by choosing a motherboard with fewer but still decent power stages, such as the Gigabyte B450I Aorus Pro with four 50 amp stages. Turn off unnecessary USB controllers to shave more power. Ultimately, you're dealing with relatively inefficient 14nm chips, and the overall power draw remains high due to the design. It’s unlikely you’ll save money unless you significantly reduce component power use, which might be limited by your power supply efficiency. At around 50 watts, your ATX power supply will likely operate near 80% efficiency.
90w seems quite low. My current draw is near its TDP—usually around 105w, sometimes a bit higher—but often over 100w. Likely the reason is the memory being overclocked. With Jedec, 90w would be reasonable. My 2700X is already open (re-lidded with paste, not LM) and running on the stock cooler. It was just as hot before the change. An 85°C reading is typical for Zen flagships, similar to the 5800X and higher models like the 5950X. Very hot. You seem to have a good deal on the 2700X. I paid near the MSRP but got it bundled from Newegg. It came with the B450M-A and 16GB Corsair 3000mhz Vengeance RAM. That memory is not great on AMD, that’s all I know. It doesn’t matter which chip you use. A 5800X under $200 probably won’t be common anytime soon, but it’s possible. I might consider one if the opportunity arises.
System load will stay near 400W across all four GPUs. The power supply will operate at 90% capacity during 50% load, using an 850W unit—this helps reach optimal efficiency because small increases in high draw quickly add up. I’ve confirmed the idle consumption is acceptable. Performance should remain strong compared to a typical i5 4590T, making it feasible to run multiple cards simultaneously. If mining becomes less profitable, I’ll revert to folding with the mining rigs. Every little saving counts, especially when free time is limited.
I noticed a noticeable difference in performance under load. At higher demands the gap between lower and higher ratings becomes more apparent, though the overall drop remains modest at around 3%. I’m feeling content with my current setup. During idle and light mining, it runs smoothly at 12W and 25W loads, with a draw near 18-20W during mining—similar to the i5 4590T. I managed to boost its clock speed to 2.2GHz without significantly impacting power usage, so even with its limited core performance this first-gen Ryzen remains strong. I plan to install the existing cards tonight, measure power consumption, and then assemble a system to safely accommodate the additional cards later this week. My goal is to achieve around 650-700W total draw once everything is in place. The two GPUs currently consume about 200W together, adding 300W during mining, which puts pressure on the available PSU. I don’t have a high-capacity unit right now; it’s rated between 600-650W, so I’ll need to rebuild before expanding further.
You need to fund the equipment and power before earning any income. Once those expenses are met, you might see a return. With a yearly maintenance cost of around fifty dollars, how long will it take to recoup your initial investment? If the machine costs eight hundred dollars, at what point does the savings become clear? We're excluding internet fees since they're needed for other purposes.
These are just what I possess, with nothing more than that extra boost. My time doesn’t matter lol.
