Default DRAM Timing

Hi All,
This is my first post here....I hope I can get some answers or directions to the answer I need.
I just bought new computer components and I have a question about the memory settings in my bios.
Here is my setup;
Asus P5E3 Deluxe x38 DDR3 WiFi-ap@n mobo
E8400 Wolfdale Retail
G.Skill F3-12800CL7D-4GBHZ PC3-12800 4 GB 2X2GB DDR3-1600 CL7-7-7-18 DUAL CHANNEL KIT
Silverstone Olympia OP1000 1000w PSU
HIS Radeon 4850 512mb

My Question is;
In the BIOS settings for the memory I have the following settings;
1st information: 7-7-7-18-6-60-10-6
2nd information: 8-6-6-7-7-4-7

How come they are not both 7-7-7-18?
How can I change the 2nd to be the same as the first information?

Greatly appreciate any help

TheRock

The 7-7-7-18 refers to your standard timings.

The rest of the numbers refer to your subtimings (tRfc and the like) It's likely that the second set of numbers is not labeled starting with CAS or latency and instead refer to something else.

To be honest, my memory subtiming knowledge just ain't good enough to help you beyond that.

Thank you for your reply.
So you are thinking that the the mobo picked up the cas latency correctly for both stick of the set?
I was just curious because I didn't want an issue with ram right from the get-go :)

cheers,

The secondary timings have nothing to do with the 7-7-7-18

The mobo will read the SPD of the RAM and set the appropriate timings if the settings are left at AUTO.

If you like to play with them, you could probably squeeze a little more performance out of your RAM, but it would really only be noticeable in benchmarks.

I will be juggling between 12-hr shifts and trying to get this new system working top shape over the next month :)
I will be reading a lot here for sure.

Cheers,
