Exploring OC, UV effects, and memory adjustments in detail
Here’s a revised version of your message:
So, welcome everyone! This is my initial post here, and I’m eager to hear your thoughts and feedback.
Secondly, I’m using the Legion graphics card from Lenovo Y540 with an Intel Core i5-9300H processor. It comes with a 6GB GeForce GTX 1660Ti, 16GB RAM (two 8GB modules), a 1TB hard drive, a 256GB NVMe SSD, and the model number is 81SX00FFUS.
Third, I have a few questions.
I’d like to ensure I get the optimal gaming performance from this setup. It’s intended as a gift for a child, and I plan to configure and fine-tune it before Christmas. I apologize in advance if you have any concerns.
Could you clarify whether it’s better to undervolt the CPU and overclock it together, or just adjust one at a time? Also, regarding the GPU—should I keep both at their default settings or lower the voltage? I understand the goal is stable performance without overheating. If I lower the voltage, does the CPU automatically adjust its speed? My i5-9300H runs up to 4.10 GHz and can boost to 2.4 GHz. So if it jumps to a higher base clock, it might generate more heat, leading to throttling. Should I find a voltage setting that keeps things cool as close to 2.4 GHz as possible, or push the CPU a bit harder and try to keep it stable? Or am I misunderstanding the whole process?
For the GPU, I’m not sure if tweaking memory is necessary unless I really need to upgrade hardware. Also, regarding TDP, should I consider lowering it or is that something I can’t control?
I’ve done a lot of research but haven’t found anyone discussing these points together. I’m looking for advice from experienced users.
Could you suggest programs for tuning the CPU and GPU? What stress-test tools would be useful? Where can I find reliable documentation to help me understand this better?
Thank you for your time, and I appreciate all your responses. I hope this clears up any confusion. If I missed anything important, please let me know. Thanks again!
Sorry about the misplacement in the Graphics Cards forum. You're welcome to relocate my message if you believe it suits that category better.
Welcome to the discussion boards! If you're looking for guidance for the future—whether it's when sharing here or elsewhere—breaking up text into paragraphs really helps. Now, regarding your questions: 1. Undervolting and overclocking can coexist, but they’re not always achievable together. It’s about navigating the unique challenges of each component. My experience with a 4790k shows that even small adjustments like a slight undervolt and modest overclock (around 1.2v @4.5 all-core) can improve stability, though reaching 4.6s consistently below 1.295 remains tough. The 9300H isn’t an unlocked chip, so it can’t be overclocked in the traditional sense. Overclocking usually just pushes performance to its limits without a dramatic transformation. 2. GPU overclocking differs from CPU overclocking. While you can boost voltage targets, actual gains often come from tweaking memory clocks rather than core speeds. Sometimes memory speed improvements matter more than CPU frequency. 3. Both undervolting and overclocking are about managing heat. Intel and AMD provide thermal guidelines (like TDP and safe operating temps) to help extend chip life. Aim for the recommended limits rather than chasing the absolute lowest temps. Laptops usually get the most attention for thermal tuning. 4. Memory overclocking is possible, but gains are modest compared to CPU work. A 16GB RAM setup should suffice if it balances speed and latency. 5. Stress testing tools like OCCT, RealBench, Cinebench, Unigine, Superposition, Time Spy, and FurMark are useful. Each offers different insights depending on your needs.
for laptops, since there is not much thermal headroom, it's usually best to leave everything stock, as the manufacturers designed the cooling and power solutions with the stock configuration in mind. they are usually well optimised and it's difficult to make significant changes without affecting something else in the system negatively. it is a powerful laptop with good components. trying to get it 10% cooler will probably reduce the performance by 20% and vice-versa so it's not worth tinkering with it.
CPU tends to be the easiest to adjust, but I’d reduce both voltages. GPU could offer significant improvement if it maintains stability. Check if allocating extra power to VRAM brings better results than increasing clock speed, since that’s common with budget models.
I think that's exactly what Semper mentioned regarding GPUs too.
