I just finished and am testing my first overclock. I used the settings from one of the forums from someone who has the same processor/mobo as I do. Everything is completely stable... Should I push farther at these load temps?

One question is my ram is now set to DDR3-1451 while it is rated at 1866mhz. The timing is 9-9-9-24. What is the best strategy? Should I try to increase mhz (and I am assuming UCLK) or work on tightening timings first? Will I see much performance difference? Again, I am new to this, so pls tell me if there is something that looks off.

Since this

i7 930 @ 3.8ghz
Mushkin 6GB rated 1866mhz
Asus p6x58d Premium
Corsair 850w modular
Diamond 5870 1GB
Zalman 9900LED cooling

Idle temp ~38C Load ~68c

BCLK 181 x 21
DRAM DDR3-1451 mhz
UCLK 2903 mhz

CPU voltage - 1.18125
CPU PLL - 1.80
QPI/DRAM voltage 1.22500
IOH voltage - 1.14
IOH PCIE voltage - 1.5
ICH voltage - 1.2
ICH PCIE voltage - 1.5
DRAM bus Voltage - 1.64

Enable XMP in bios for your ram so it will run at advertised speed up the Dram voltage to 1.66v

that should do it although it would be more helpful if you were a little more specific
about your ram like the model #

Here is the model -

Mushkin Enhanced Blackline 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 15000) Desktop Memory Model 998834

http://www.newegg.com/product/product.aspx?Item=N82E168...

The voltage listed on spec by Newegg is 1.65.
Is it safe to bump it up to 1.66v?

Most important question is should I expect a noticeable performance boost from DDR3 1451 up closer to DDR3 1866?

If your running it at 1451, you don't need 1.66v, it will probable be stable at 1.60v.....test

NOPE, you won't see any difference.
