Odd modules? (Dominator GT)

[Smartidiot89]

I baught a pair of memory modules that were selling out for a cheap price of €100(atleast I think that was cheap...) but when looking in BIOS and CPU-Z something doesn't look right?

To be more precise this is the kit:
2 x 2GB Corsair Dominator GT 1600MHz CL6 1.65v w/ memoryfan - looking at the modules it says Rev 2.1

Now these sticks are verified to work with Intel Core i5 and Core i7 with Intel XMP at these settings:
1600MHz 6-6-6-20-41-2T 1.65v

But the odd thing is only one of the stick has the Intel XMP inside, while the other looks like some JEDEC-standard module. So here are the part-numbers for both sticks:

• CMT4GX3M2A1600C6
• CM3X2G1333C9D

Now should I care about these or should I expect them both to work as advertised?

EDIT: If you wouldn't mind, what IC's are this kit using?

Thanks in advance you bearded workers!

The IC listings are stickied at the top of this section. Have you actually tested the modules yet to see if they work at specification? Also, did you buy them from an individual or an authorized reseller?

I bought them from an authorized reseller and I was the one to open up the box.

It seems to run good on it's specified settings, but will retest just to be sure... Just think it's weird both have different part-numbers is this something you usually do at Corsair with Dual/Triple-Channel kits?

Yepp, tested the sticks thoroughly and they work as specified. Still find it strange that one of the sticks doesn't have Intel XMP and follows JEDED 1333 9-9-9-24-34 standard according to CPU-Z but as long as it works I don't care I guess.
