| Component | Validator Requirements | Additional RPC Node Requirements |
|---|---|---|
| CPU | - 2.8GHz base clock speed, or faster - SHA extensions instruction support - AMD Gen 3 or newer - Intel Ice Lake or newer - Higher clock speed is preferable over more cores - AVX2 instruction support (to use official release binaries, self-compile otherwise) - Support for AVX512f is helpful |
|
| 12 cores / 24 threads, or more | 16 cores / 32 threads, or more | |
| RAM | Error Correction Code (ECC) memory is suggested Motherboard with 512GB capacity suggested |
|
| 256GB or more | 512 GB or more for all account indexes | |
| Disk | PCIe Gen3 x4 NVME SSD, or better, on each of: - Accounts: 500GB, or larger. High TBW (Total Bytes Written) - Ledger: 1TB or larger. High TBW suggested - Snapshots: 250GB or larger. High TBW suggested - OS: (Optional) 500GB, or larger. SATA OK The OS may be installed on the ledger disk, though testing has shown better performance with the ledger on its own disk Accounts and ledger can be stored on the same disk, however due to high IOPS, this is not recommended The Samsung 970 and 980 Pro series SSDs are popular with the validator community |
Consider a larger ledger disk if longer transaction history is required Accounts and ledger should not be stored on the same disk |
| GPUs | Not necessary at this time Operators in the validator community do not use GPUs currently |
Recommended Hardware

Agave CPU
AMD is the CPU maker of choice when it comes to running Solana validators. Running Intel processors for a new validator is strongly discouraged. Intel Xeon Gold/Platinum (6[45]xx) are the only ones known to be able to possibly keep up with the chain.
NOTE: This list is not exhaustive, just a selection of CPUs different folks on the discord have run or are currently running.
- 24 cores is the sweet spot, as of 10/2024,
- 12/16cores will most likely struggle and,
- more than 32 cores will have a slower base clock speed due to TDP issues (32 cores would possibly be more future proof)
| Recommended | Manufacturer | Model | Base Clock | Max Boost Clock | Cores | Threads | Default TDP | PoH speed * |
|---|---|---|---|---|---|---|---|---|
| Yes | AMD | Ryzen™ Threadripper™ PRO 7965WX | 4.2 GHz | Up to 5.3 GHz | 24 | 48 | 350W | 22.2M, 20.4M |

| Yes | AMD | Ryzen 9 9950x | 4.3 GHz | Up to 5.7 GHz | 16 | 32 | 170W | 23M |
| Yes | AMD | AMD EPYC™ 9254 | 2.9 GHz | Up to 4.15 GHz | 24 | 48 | 200W | 17.5M |
| Yes | AMD | AMD EPYC™ 9354P | 3.25 GHz | Up to 3.8 GHz | 32 | 64 | 280W | 16.1M, 14.4M |
- Recommendation from version Agave 2.1.1 is to have at least 10M hashes/sec. Results based on governor set at performance mode.
These recommendations also work for RPC nodes, but RPC nodes require more cores and RAM to perform better under load

Swap
Running swapfiles is highly discouraged since it masks problems with your setup and will lead to negative consequences as chain activity increases.

notes to consider for renting:
- check reviews on the solana discord for your specific provider.
- ensure you are not running within a virtual machine (vm).
- verify the speed and uplink of the provider; low latency is crucial.
- ask the provider about the hardware specifications, focusing on higher ram frequencies.
- before using your validator, confirm that all hardware components are functioning as expected.
free to test for beginners
some providers offer a test phase before you commit to renting with them, often as a playground to explore running a solana node. you can check the list, which we update frequently with new providers.
Notes
-
CPU Selection: Prioritize CPUs with higher base clock speeds to meet Solana validator performance requirements. Ensure the selected CPU supports at least AVX2 instructions, with AVX-512 providing additional performance benefits. The AMD Ryzen™ Threadripper™ PRO and AMD EPYC™ series listed above are optimized for high-performance and multi-threaded tasks essential for validator operations.
-
Storage Selection: Choose NVMe SSDs that offer high IOPS to handle the intensive read/write operations necessary for validator nodes. Samsung’s Pro series and WD’s SN850X are highly recommended for their reliability and performance within the validator community.
-
Memory Considerations: While not part of the table, remember that RAM requirements are crucial. Ensure you have ECC memory and sufficient capacity as per the Hardware Recommendations section. RAM speed and DDR4 vs DDR5 are not known to make any significant differences

FAQ
Q: My validator doesn’t catch up or catches up slowly or does not keep up with the tip
A: If you’ve followed the setup instructions correctly, make sure to: (via ax on discord)
i would like to suggest using the acronym “core” when beginners are asking for help, because its always the same question with same answers. it helps to break down the steps and make the guidance easier to follow:
- c: check cpu performance (focus on single-thread speeds)
- o: optimize nvme by separating ledger and accounts
- r: remove unnecessary cli arguments
- e: enable performance mode
setup performance mode
sudo apt install cpufrequtils
sudo bash -c 'echo performance > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor'
