Hi everyone

I recently upgrading my computer for gaming and I read that a 1 to 1 ratio FSB:D RAM is the best and most stable setup.

I am unsure how to do this a could anyone please tell me how to set this up.

My cpu is a 3570k i5 quad core processor

My motheboard is a gigabyte Z77X-UD5H

My Ram is Kingston DDR3 1600 (PC3 12800) KHX1600C9D3LK2/8GX

I am trying to achieve a 1:1 ratio for FSB:D RAM

Could someone tell me the formula or what to change the numbers to and which numbers?

Here are my stats from my gigabyte BIOS:


CPU/PCIe Base Clock: 100 MHz

CPU Clock Ratio: 34


System Memory Multiplier: 16

Memory Frequency: 1600 MHz


Standard Timing Control

CAS Latency: 9

tRCD: 9

tRP: 9

tRas: 27


Advanced Timing Control

tRC: 36

tRRD: 5

tWTR: 6

tWR: 12

tWTP: 24

tWL: 8

tRFC 126

tRTP: 6

tFAW: 24

Command Rate (tCMD): 2

tRW Stability level: 3

Please help me achieve a 1:1 FSB to DRAM ratio for gaming.

Thank you everyone for reading and helping me. Thank You.

The 1:1 FSB/RAM ratio only mattered with LGA 775. LGA 1155 is completely different and does not even have an adjustable FSB anymore. Your computer is fine as is.
