NEW Memory - Higher Speed - Overclock Setting Changes needed

[JFC15]

I purchased new memory for my computer and need assistance with making changes to get the memory frequency upto 2133. Below are all my current BIOS settings. Any help (changes) , even in other parts, would be appreciated.

What are the memory multipliers that the BIOS makes available to you?

I would try changing BCLK to 200 MHz and reducing your CPU multiplier to 18. That should give you 2000 MHz memory clock and the same CPU clock. When you start trading off CPU multiplier and BCLK, the voltage the MB delivers may change so you would probably have to adjust that too. Then run prime95 or IBT to make sure it is still stable. After that, if you have an 11x memory multiplier, then you can change to that and be there (after checking stability again).

Thank you for the reply, but from what I've read, a CPU Clock Ratio of 21 on an i7-920 allows the processor to adjust speeds - only being at a higher speed when needed... the rest of the time it drops to 12 or so (according to CPU-Z) That is less wear and tear on the processor with less heat. If the CPU Clock Ratio really doesn't make much of a difference, maybe I'll take a look at lowering it and raising the BCLK. I did see that if I raised the SPD to 12, I went to 2172... a little over the memory rated 2133. But I didn't have enough time to play around with making other changes because it wasn't stable. Your thoughts?

That is only a slight memory overclock. It should probably work, but you should run extensive memtes86+ and prime95 blend with a large memory footprint to make sure it is stable.

Correct me if I am wrong, but if you have a X58 board should this not be running triple channel memory? Either 6 or 12gb?

I assume you have put Dual channel memory into it and have 2 spare slots now.

I don't know much about memory but that may cause you some issues I am really not sure though.

Sorry I can't help with the settings as I have a P67 board myself.

Good luck though.


Paul.

Technically, you are correct. But with this specific motherboard, I can run triple channel using slots 1,2,3,5. I verified that through Gigabyte tech and using MemTest86. The problem I'm having is when I lowered the RAM timings from 9-10-11-28-2 to 8-9-9-27-1, my GFlop when from 50 to 48. I had both settings stable with only minimal changes. I'm hoping someone can explain to me why my computer actually got slower with better RAM timings and "MAYBE" give me pointers on what settings to adjust to make it better... THANKS!!!
