Should I return this and get other kit

I am current running this kit
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145236
OC at 1740Mhz 9-9-9-24-T2 with 1.66V. I can't get pass it even with more step up. I believe it's due to my MB limit Bclk at 219 bclk.
Since I just bought this kit, I can still return it and get this kit.

main reason I want tighter timing at 1740Mhz. which I can't get current Corsair XMS to do it.

What do you guys think? is it worth $10 extra?

If anyone wondering, here is my setup.

I7 930 OC at 4566Mhz HT on with 1.54vcore
MSI X58 pro-e
watercooler GTZ block.
1000W antec power supply
ATI HD5870
Corsair XMS 1600Mhz
2 x 30G SSD raid 0 for OS
1.5T Storage HD

I wouldn't...not worth the hassle for so little. Besides aren't the xms sticks doing their rated timings at their rated speed?

yes, it run fine with rated speed and voltage.

There will always be something a wee bit better. Enjoy the excellent memory you have.

I would dump Corsair and get either Gskill or OCZ, but then that's just me.
