Hyper X blu CL9 @1600Mhz or Fury CL10 @1600Mhz

[Jayant Arora]

Well i had 2x 4GB hyper x blu, going to buy 4GB more in future, but seems like for hyperx blu the times has passed, luckily i found it online, It bugs me always what's the difference brw 1,65v ram and 1.5v ram anyways, also i see blu on XMP can go CL9 while fury is CL10 . can it go XMP to get CL9, Secondly i don't have the budget right now so certainly i have to mix them in future, can they work together like fine with CL9 i don't thin so fury @1600MHZ can run at CL 10 only as per specs so it should be slower than BLU @1600MHZ @XMP, insin't it?? I'ts the main spec the speed?? It would be a downgrade i fi mix?? also i would be running tripple/quad channel @CL 10. So whats the call here?? 1. i buy RAM now loan the money as i would probably miss the chance 2. Leave it to luck and wait till i got the budget 3. MIX . My Specs: t I had ci5 4460 GTX 970 Asus Strix and z78m-g43 MSI MB

It is a crapshoot to mix ram.
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.
It is safer to get what you need in one kit.

Ram with a 1.65v spec is really 1333 1.5v ram that is of sufficient quality that it can run at higher speeds when overclocked to 1.65v.

I am all in favor of lots of ram, but I suggest you buy a 2 x 8gb kit of the cheapest ram you can find.
Ram speeds are largely irrelevant to haswell if you are using a discrete graphics card.

Haswell will run only dual channel, regardless of the number of sticks.
If the capacity on each channel is not equal, the excess will simply run in single channel mode.

Mixing the 2 can be rather problematic, never a good idea to mix just for starters, then these have different voltages, different timings use use different info in the SPD, the Blu are XMP based, where the Fury are PnP based
