A bit of help with

post #1 of 4
Thread Starter 
Hello,
I have this computer

Intel Core I7 920 2.66Ghz Box Socket 1366
Asus P6T Deluxe V2 Socket 1366
Scythe Mugen 2 CPU Cooler
MSI GTX 570 OC Edition
Mushkin Essential DDR3 PC3-16000 6GB 3x2GB 9-10-9-24
Western Digital Caviar Black 1TB SATA2 MAESTRO
Cooler Master HAF 932
Corsair HX850 850W Modular

Today I decided to OC my I7 920 usinfg this parameters

CPU ratio 21
BLCK 175
PCIE 100
CPU volt 1.20
QPI /DRAM core voltage 1.35

And so far working well.
But when I was using the CPU-Z I saw that my memories where not with the right timings.
I went to the DRAM section of the bios and changed the frecuencies to 9-10-9-24
I changed the voltage to 1.64

But When I try to change the speed, I go to the BIOS, go to DRAM Frecuency but I dont have 1666. I can only select 1053,1403,1754,2105,2455.
Why is this? I am pretty noob to OC, so pls let me know what am I doing wrong. So far CPU-Z tells me that my memories are running at :

NB fracuency 2800Mhz
DRAM Frecuency: 525
FSB:Dram 2.6
9
10
9
24
Row refresh 44 clocks
Comand rate 1T

How can I set up the memories to 1600? Any help is welcome!
Also any other suggestions about this OC are welcome, as I said, I just tried today, and you have up there everthing I changed.

Memory speed is tied to BCLK, so if you change that, memory speed will change with it. You'll need to either run your memory at a different speed, or change your BCLK to 200 or 160 so you can use your memory at 1600.

What would you suggest with my set up?

Try BCLK at 200, with a CPU multiplier of 19. That will allow you to run your RAM at its rated settings and give you a CPU frequency of 3.8 GHz. You may have to raise vcore a bit, depending on your chip.
You can probably lower QPI/DRAM voltage by the way, 1.2-1.25 should be plenty.
