About 512 GB RAM dedicated server
512 GB is where big-data workloads start being fully in-memory feasible. Large graph databases, multi-TB ClickHouse hot data, ML training with big batch sizes, or dense virtualization hosts with 100+ VMs — this is your tier.
Two platform families: (a) dual EPYC Rome/Milan — 128 physical cores, DDR4-3200 across 16 memory channels (~410 GB/s aggregate bandwidth), best price-per-core; (b) dual Xeon Platinum 8168 — 48 physical cores, DDR4-2666, AVX-512, best single-thread performance.
Typical customers on 512 GB tier: fintech backtesting stacks, ML training clusters for mid-size models, dense multi-tenant VPS/KVM hosting (50-100 VMs per box), private cloud infrastructure, ClickHouse analytics on 5+ TB hot data.
Both platforms expandable to 1-1.5 TB RAM. NVMe Gen4 available (EPYC), Gen3 on Xeon Platinum. Uplinks: up to 100 Gbit/s unmetered on QSFP28. Custom-quoted per build, 48-72 h provisioning.
Frequently asked questions
512 GB DDR4 vs 512 GB DDR5 — worth the price?
DDR5 gives ~40% more bandwidth (4800 MT/s vs 3200) and better power efficiency. Worth it for bandwidth-bound workloads (in-memory analytics). Not worth it if you're CPU-bound.
Can I run a full 500 GB database in RAM?
Yes — with a 512 GB box you can fit a 400+ GB database entirely in RAM (leaving headroom for OS cache and processes). Query latency drops by orders of magnitude vs SSD.
How much does 512 GB cost to upgrade later?
On EPYC — ~$800 one-time hardware + 30-45 min downtime for the swap. On Xeon — similar. Usually cheaper to spec 512 GB upfront than upgrade in 6 months.
