Need help with GIGABYTE GA-EP43T-USB3 (RAM)

[lola99]

I bought this motherboard 3 months ago. Two weeks before I suddenly noticed that my DDR3 1333 BUS ram is working in 1066. I tried every possible way for 1333 but I couldn't do it. Please please, can anyone help? I asked a lot of people but they couldn't solve it..

Config:
Core 2 Quad Q6600
4 GB DDR3 RAM (1333 BUS) Silicon Power
GIGABYTE GA-EP43T-USB3
Samsung 1 TB

With default 266MHz FSB DDR-1066 is the maximum possible.
To run the memory at DDR-1333 at leat 333MHz FSB is required, and a slight overclock of the CPU.
Please attach a text report of CPU-Z (about tab), you cam download it from http://forums.tweaktown.com/gigabyte...ity-tools.html

I have never overclocked anything processor or ram although I know about them. So I have very little practical knowledge about them. I have attached the text file. You have to tell me in details if it is possible for you. And thanx a lot Chike...

The memory SPD

JEDEC timings table CL-tRCD-tRP-tRAS-tRC @ frequency
JEDEC #1 6.0-6-6-17-23 @ 457 MHz
JEDEC #2 7.0-7-7-20-27 @ 533 MHz
JEDEC #3 8.0-8-8-22-30 @ 609 MHz
JEDEC #4 9.0-9-9-25-34 @ 685 MHz

I Would begin with profile #3, ram at 1216 with timings 8-8-8-22 and max CPU at 2432MHz (minimal OC)
Load optimized defaults and try the following changes:

All the rest at their default settings.
It's recommanded to run memtest86+ before starting windows, also 6+ hours of Prime95 blend torture.

Thnx a lot Chike specially for this detail process. I got the best response from you. 'It's recommanded to run memtest86+ before starting windows, also 6+ hours of Prime95 blend torture.' do I really have to do that? Because I am no expert in them. Whatevr it is, I will try your method without this two and get back to you.. And thnx again...

Those are just to make sure the settings are stable. They may or may not be stable, better to know it and try to stabilize them instead waiting for random crashes.

EDIT: memtest is easy to install on a bootable USB flash druve, and Prime95 is even easier to run.

Oops I just notices I forgot the FSB...
