Hi, I bought 2x2Gb OCZ PC2-6400 Gold Edition DDR2 for my GIGABYTE GA-P35C-DS3R with 2x2GB Kingston KHX6400D2K/4G. I put them together and my Computer freezes on the WELCOME screen of WiN 7 64bit. How set the RAM in Bios ?
Here the screen of CPU-Z OCZ first (separately) Kingston second

First, it's not a good idea to Mix-Match RAM: Frequency, CAS, Type (including Brand/different IC's). No Guarantees.

Specs - ref http://www.gigabyte.us/products/product-page.aspx?pid=2...
DDR2:
4 x 1.8V DDR2 DIMM sockets supporting up to 8 GB of system memory
Dual channel memory architecture
Support for DDR2 1066*/800/667 MHz memory modules

DDR2-667 5-5-5-15-20 @1.80v
DDR2-667 5-5-5-15-20 @1.80v
=======================
DDR2-667 5-5-5-15-20 @1.80v

5 CAS
5 RAS to CAS
5 RAS PRE
15 tRAS
20 tRC

Slots:
CPU: | New | Old | empty | New | Old | empty |

Channel 0: DDRII1, DDRII2
Channel 1: DDRII3, DDRII4

BIOS:
System Memory Multiplier -> 2 ; 2 * 333MHz = 667MHz
Memory Frequency (Mhz) 667 ; verify Frequency
DRAM Timing Selectable -> Manual
CAS Latency Time -> 5
DRAM RAS to CAS -> 5
DRAM RAS PRE -> 5
tRAS -> 15
??? tRC -> 20 ; {Row Cycle Time} minimum tRC = tRAS + tRP ; your manual I downloaded has no Timing info. You BIOS 'should' calculate a safe value.
DDR2 /DDR3 OverVoltage Control -> +0.10v ; optional but often helps with 4x_GB

Save & Exit = Yes

Big Thanks it works :hello:  System Memory Multiplier was the main thing in setting what I missed. :bounce:
