Overclocking i7 13700k model
I've been experimenting with boosting my CPU, RAM, and ring clock settings. Since I'm new to Intel technology and DDR5, everything feels unfamiliar. My current setup includes an i7-13700K, 32GB of 2x16 Trident Z7, a Z790 Aorus Elite Ax, EVGA 1000 T2 PSU, and an MSI RTX 4090 Noctua NH-D15s. I've got these overclocks: the CPU at 5.4GHz all-core at 1.24V, HT disabled, E-cores off, a 7000MHz CL32 at 1.45V (stock is 6600MHz at 1.4V). I was a bit careless with tuning voltages and could probably improve them. The CPU handles around 80°C under stress, 60°C during gaming, and 40-50°C at idle. A ring clock of 4.7 is fine, but 4.8 causes BSOD on startup—though it uses the same voltage as the CPU, I don’t want to exceed that. RAM is stable at 7000MHz; I’m unsure about pushing further with a 7200MHz option. Heat stays around 40°C with these configurations. There are many RAM timing and settings I’m still learning about. Looking for general overclocking advice, plus guidance on which voltages to adjust and how to tweak timings or RAM speeds.
Assume your LLC configuration might be off. If 1.25V seems too high and impacts stability, consider lowering it to around 1.4V or even 1.25V—this usually gives enough power for a solid 5.5GHz run, possibly reaching 5.6GHz. Most boards perform best with moderate or low LLC settings, so start there and adjust. Expect higher overclocks at lower voltages, though you’ll likely face a bit more heat (especially around 40-50°C). This is fine if your chip supports it.
Key voltages for boosting performance include VCore, CPU PLL, and Ring PLL. SA and SA PLL can help with ring overclocking when needed. VCore should be raised until you hit heat limits; other settings are more about fine-tuning. Your chip usually thrives at about 1.05V for all three PLL voltages, though some models prefer slightly lower values.
For memory overclocking, focus on VDDQ TX, VDD2, SA, DRAM VDD, DRAM VDDQ, Ring PLL, SA PLL, MC PLL, and VCCIN. These points have optimal ranges, and their ideal values shift with BIOS versions. Your chip generally does best with 1.05V on these, but variations exist.
System Agent is unusual—Ring clock usually keeps growing with higher SA voltage, while memory overclocking has a narrower sweet spot. Keep it below 1.45V for CPU health, especially at your current speed. For memory, aim for stable values; only tweak if you notice instability after a while.
For DRAM settings, match VDDQ to VDDQ TX, and set VDD2 as a baseline. Some boards prefer 1.35V, others stick to 1.65V. It’s wise to test these ranges and see what your board handles best.
Check Buildzoid guides for guidance on 13th-gen memory settings—they cover tricky relationships. Tools like MemTweakIt can help you explore timing options safely. Keep in mind, extreme tweaks can cause crashes or instability, so proceed cautiously.
I believe the high idle temperature comes from having all dynamic frequency/boosting features turned off, which means it runs at full speed and voltage continuously. I set the LLC to normal and raised the SA voltage, achieving 5.5 working and 4.8 ring. I’ll keep working on it.
tRTP is present on my system but not on yours. I still have tRDPRE installed. I also saved many of those timings and it started working properly. Setting RAM to 7200 MHz doesn’t seem to help, as I keep getting BSODs regardless. It might be an issue with your hardware.
tRTP is present but has issues in most BIOS except for ASUS. It may not work, lead to training errors, or only support higher values like 16. The frequent BSODs could stem from timing constraints or incorrect memory controller voltage settings. Try adjusting VDDQ TX and VDD2 voltages to see if it improves things. The exact labels for these settings aren’t clear to me yet.
VDDQ CPU is the component I'm focusing on that influences memory controller performance. Most users prefer setting it to 1.35V and keeping it stable. Some boards, especially from Gigabyte, tend to require higher VDD2 levels, so consider increasing it slightly to test stability. However, adjusting the actual memory voltages is necessary—exceeding 100mV between them can cause unintended voltage flow through parts not meant for it. From my experience, these boards generally reject memory voltages above 1.435V. There are a few clear issues I notice right away. First, tWTR isn't a real timing metric on Intel; it's derived from tWRRD_sg and tWRRD_dg in the tertiary stages. In practice, leaving them on auto is usually safest since they can introduce unpredictable problems and often lack sufficient headroom. Second, tRTP 6 either isn't active or is overly restrictive. It's uncommon to find a die with a die count below 10, let alone 6 like M die does—though it seems tRDPRE timing is being used in some cases. Third, tRRD_L appears too tight; few A dies remain stable at 7, and some even struggle at 8, though this is rare. The tWRPRE 40 also looks very tight, which could help if you're targeting CAS 32, as its stability depends heavily on CAS latency. Generally, I opt for a looser setting (around 60) if uncertain. Command Rate 1 won't be feasible at 7200MT/s; achieving it reliably is difficult, especially at speeds above 6800MT/s. If you're using A dies, aim for 2T to maximize clock speed.
