DIFFERENT MEMORY SPEED IN CPU-Z Tags: Memory Dram Frequency CPUs Last response: July 6, 2010 5:22 PM in Memory Share HolyDoom Witch July 6, 2010 4:45:48 PM Why should the CPU-Z report my memory's DRAM Frequency as 333.3? The JEDEC #1 is 333.3, and #2 is 400. But I don't understand this. The "Max Bandwidth" section says: PC2-6400 (400 MHz) I had got a single stick of 2mB of RAM installed that should have been of 800 mhz. Is this the case? Because I had thought that 800 x 2mB would become 1600 mhz! Earlier I had 667 MHz.

Also, have you went into your BIOS and adjusted the memory settings to match what is on the RAM (voltage, timings and speed)?? | Report abuse HolyDoom Witch July 6, 2010 5:22:47 PM Here is the info on the "Memory" tab: --General--------- Type: DDR2 Size: 2048 MBytes Channels #: Single DC Mode: empty NB Frequency: empty ---------------------------------- --Timings--------- DRAM Frequency: 333.3 MHz FSB : DRAM: 4:5 CAS# Latency (CL): 5.0 clocks RAS# to CAS# Delay (tRCD): 5 clocks RAS# Precharge (tRP): 5 clocks Cycle Time (tRAS): 15 clocks Bank Cycle Time (tRC): 21 clocks [The last four rows "Command Rate (CR)", "DRAM Idle Timer", "Total CAS# tRDRAM)", and "Row To Column (tRCD)", are empty.] | Report abuse Ask the community Publish Tom's Hardware>Forum>Memory>DIFFERENT MEMORY SPEED IN CPU-Z> Related ressources: ForumDifferent memory speed in BIOS and CPU-Z ForumTwin ddr3 memory showing different speeds in cpuz ForumDid I ruin my CPU?
