DA - montăm RAM client-supplied fără probleme!

RECOMANDARE STRONGLY: Consultare prealabilă verificare compatibilitate!

Factors check compatibility:

1. DDR generation (DDR4 vs DDR5):
• DDR4 și DDR5 = physically incompatible (notch position different) = impossible insert wrong type (protection design)
• Motherboard supports DOAR 1 type: DDR4 SAU DDR5, NOT both!
• Check motherboard specs: CPU-Z tab "Memory" → Type shows "DDR4" sau "DDR5"
• Verificare online: Motherboard model Google → Specifications page → "Memory Type: DDR4" clear listed

2. Frecvență MHz support:
• RAM speed (ex: 3200 MHz, 3600 MHz, 5600 MHz) trebuie supported motherboard
• Example issue: Buy RAM DDR4 4000 MHz DAR motherboard max support 3200 MHz = RAM va funcționa DAR downclocked la 3200 MHz = waste money premium speed!
• Check motherboard QVL (Qualified Vendor List): Site producător motherboard → Support → Memory QVL = listă RAM tested compatible with motherboard = safest choice!
• General rule: DDR4 mainstream motherboards support up to 3200-3600 MHz nativ, higher speeds (4000+ MHz) necesită manual overclock BIOS risky

3. Voltage rating (1.2V vs 1.35V vs 1.5V):
• Standard DDR4 = 1.2V JEDEC spec, DDR4 "gaming" RAM = 1.35V (XMP overvolted), extreme overclock = 1.5V+ (risky long-term!)
• Majority motherboards handle 1.35V fine (XMP enabled automatic), DAR budget motherboards (A320, H410) poate limit 1.2V = compatibility issue
• Check RAM spec sheet voltage rating match motherboard tolerance

4. Capacity per slot & total capacity:
• Motherboard max capacity per slot: Ex: 16 GB/slot × 4 slots = 64 GB total max
• Older motherboards (pre-2018) limited 8 GB/slot = 32 GB total max (2×16 GB won't work!)
• Check motherboard manual: "Memory: 4× DIMM, max 128 GB" = clear capacity limit

5. Single-rank vs Dual-rank modules:
• Technical: Rank = how memory chips organized module (single-rank = 1 side populated, dual-rank = both sides)
• Performance: Dual-rank slightly faster (+2-5%) DAR some motherboards compatibility issues mixing single/dual-rank
• Best practice: Buy matching kit (ex: 2×8 GB same brand/model/speed = guaranteed compatibility)

Serviciu nostru verificare:
• Trimite photo RAM cumpărat (label spec sticker visible) + motherboard model → Verificăm compatibility 100% ÎNAINTE instalare = zero risc incompatibility surprises!
• Dacă incompatibil detected = advisory alternatives compatible + opțiune return RAM (dacă sigiliu intact) vs keep + resell OLX = avoid waste money

Cost manoperă: 100 RON instalare RAM (client-supplied sau sourcing nostru, price identic)

DA - garanție manoperă + hardware (dacă sourced prin noi)!

Garanție manoperă instalare: 30 zile
• Dacă probleme POST/boot/stability din cauză montaj improper (ex: RAM nu seated correct = intermittent detection, slots wrong populated = single-channel instead dual) = revenire FREE remontaj correct
• Dacă RAM Memtest86 errors detected post-install = investigare cauză: RAM defect vs motherboard slots issue vs compatibility problem = clarify accountability

Garanție hardware RAM (dacă cumpărat prin noi):
• Lifetime warranty brands premium: Kingston HyperX/Fury, Corsair Vengeance, G.Skill Ripjaws/Trident = lifetime warranty transferable (as long as own RAM, replaceable dacă defect)
• Limited warranty brands budget: Patriot, Team Group, ADATA = 5-10 ani warranty typical
• Proces RMA: Defect detected (Memtest86 errors persistent, Windows crashes MEMORY_MANAGEMENT BSOD) → Contact brand support (online form + invoice/receipt) → RMA number issued → Ship RAM return (prepaid label provided majority brands) → Replacement shipped 1-2 săptămâni
• Serviciu nostru handle RMA: Dacă RAM cumpărat prin noi = handle entire RMA process behalf client (forms fill, shipping arrange, follow-up) = zero hassle client!

Garanție hardware RAM (client-supplied):
• Warranty responsibility client (garanție producător original, client ownership invoice/receipt)
• Noi verificăm compatibility + proper installation DAR hardware warranty remains client's (logical, we didn't sell hardware)
• Dacă RAM defect suspected post-install = diagnostic Memtest86 + verification slot different (isolate defect RAM vs motherboard issue) = clarity fault identification

Excepții garanție (NOT covered):
• Physical damage client-caused (bent pins slots, liquid spill, electrostatic discharge improper handling post-install)
• Incompatibility issues (ex: client insisted RAM specific brand/model against our compatibility advisory = responsibility client)
• Overclocking extreme settings BIOS (RAM rated 3200 MHz pushed 4000 MHz unstable = void warranty manufacturer!)

Peace of mind: 95%+ instalări RAM = zero issues (hardware ultra-reliable, installation straightforward), garanție = insurance policy rare edge cases!

Steps verificare compatibility DIY:

1. Identificare DDR type current:
• Download CPU-Z free (cpuid.com/softwares/cpu-z.html)
• Launch → Tab "Memory" → "Type" shows "DDR4" sau "DDR5"
• SAU: Open case → RAM modules au label sticker (ex: "DDR4-3200 16GB") = DDR generation visible

2. Check motherboard model exact:
• CPU-Z tab "Mainboard" → "Manufacturer" + "Model" (ex: "ASUS PRIME B550M-A")
• SAU: Physical inspection motherboard silk-screen print near RAM slots (model number printed PCB)

3. Consult motherboard specifications online:
• Google "[Motherboard model] specifications" (ex: "ASUS PRIME B550M-A specs")
• Official manufacturer page → Specifications section → "Memory":
  → Type: DDR4 (confirm DDR generation)
  → Speed: 3200 MHz / 3600 MHz / 4000 MHz (O.C.) = max supported speeds listed
  → Slots: 4× DIMM = total slots available
  → Max capacity: 128 GB = total RAM maximum supported
  → Max capacity per slot: 32 GB = individual module size limit

4. Download motherboard QVL (optional DAR recommended!):
• QVL = Qualified Vendor List = RAM kits tested compatible motherboard specific
• Manufacturer support page → Downloads → "Memory QVL" PDF/Excel file
• List shows: Brand (Kingston, Corsair), Model (KHX3200C16D4/8G), Speed (3200 MHz), Capacity (8 GB), Status (Tested OK / Tested fail)
• Choose RAM listed QVL = highest compatibility confidence (99% guaranteed work!)

5. Match RAM specifications shopping:
• Example motherboard supports: DDR4, max 3600 MHz, 4 slots, 128 GB total, 32 GB/slot
• Shopping criteria: Buy DDR4 (NOT DDR5!), Speed ≤3600 MHz (ex: 3200 MHz safe choice), Capacity per module ≤32 GB
• Configuration examples valid:
  → 2×8 GB DDR4 3200 MHz = 16 GB total (occupy 2 slots, dual-channel, room expand viitor +16 GB)
  → 2×16 GB DDR4 3600 MHz = 32 GB total (occupy 2 slots, dual-channel, room expand +32 GB viitor)
  → 4×16 GB DDR4 3200 MHz = 64 GB total (occupy ALL 4 slots, quad-channel vissa motherboards support, maxed out)

6. Avoid common mistakes:
• ❌ Mixing DDR generations (DDR4 + DDR5 = physically impossible, notch different)
• ❌ Exceed motherboard max capacity (ex: buy 4×32 GB = 128 GB DAR motherboard max 64 GB = wasted 64 GB!)
• ❌ Buy speed way higher motherboard support (ex: DDR4 4800 MHz RAM DAR motherboard max 3200 MHz = waste premium cost, downclock automatic)
• ❌ Single-channel config (ex: 1×16 GB stick when 2×8 GB kit same price = dual-channel 2×8 GB bandwidth +30-50% faster!)
