Is Hyper X Fury CAS 9-9-9 Possible?

[jayantfordreams]

I have 2x4gb hyper x blu ram @1600mhz, these models are been replaced by hyper x fury and are no longer avalable in market, i've seen people mixing them and it works.
See the Blu can run at CAS 9-9-9 @1600MHz in XMP mode, while fury runs at @1866 CAS 10-10-10 default .
As per specs it has programmable CAS of 9,10,11 with frequencies 1333,1600,1833.
The thing i don't know if i mix blu and fury, can fury run at 9-9-9 CAS @1600Mhz?? which will make it to mimic the blu model exacltly.
If not what would be the best possible configuration i will be getting with:
2x4Gb blu + 2x4GB fury
?-?-?CAS@xxxxMhz ?-?-?CAS@xxxxMhz
UPDATE:
ANSWER FOUND: IT WILL

One way to find out....give 9-9-9 @1600 a go. It would most likely work.

Wouldn't ask this question if i had it.....I Don't have it i'm going to buy it if it works. It's upto u guys if any one knows.

What voltage are the RAM sticks rated at separately? And what voltage are the sticks running at on BIOS itself? Since AFAIK the BIOS is hardwired to run all memory sticks at the same voltage no matter what.

It should work if the computer boots, the only thing you should watch out for is stability, so run Memtest to check if any errors pop up.

I don't think there's any reason for you to try completely matching your other RAM stick timings if you mixed them, since the performance increase or decrease in some cases will be marginal at best.

Buuuuut...... Since you want to run the higher clocked Fury at a lower latency, you should be able to go with 1600MHz 9-9-9-24/27 easy, just remember that it might require a voltage bump, unless the Fury stick already runs at 1.65v, increasing voltages beyond that for memory isn't a good idea, I personally don't recommend it. I think most XMP 1866 sticks do require 1.65v to run optimally.

IMO the best way to run mixed RAM is to make channel B (secondary) sticks run as closely to the slowest RAM stick in channel A (primary) as possible to avoid having more of something called "hard faults", you can look up on the internet what that means for PC's, it's nothing to worry about much.

My personal experience:

I mixed Corsair Vengeance 2x2 1600MHz 9-9-9-24 with a single Kingston HyperX Savage 9-9-9-27 stick, both are 1,5v though, which is favorable, lower voltages are healthier. And I saw no issues with running them as BIOS likes them, granted I could run them at 1866 10-10-10-30 but the Z67 bios on my MB is very fragile and especially doesn't like any kind of deviation of clocks or voltage when paired with a non-K processor such as mine.

I never tried the unofficial beta bios made by one guy, reason being it disables some features and also messes with voltage stability, so it's not recommended for me to use that when the board works OK for the most part without UEFI. (Except when I need to get into BIOS and the board decides to turn off the keyboard, disable the middle mouse button or forgets to OC from a cold boot. No wonder the guy that owned it before returned it to the retailer, because it has all sorts of nuances that I wouldn't like to deal with on a daily basis.)

1.5V for blu and i don't have fury ram yet.. fury can run at both 1.5 and 1.35 V modes

Ok I found the answer and it's pretty neat and direct:

See this:
Announced at CES 2014, Kingston has released their replacement of the Blu series of RAM modules. Named “Fury,” the new HyperX series of DDR3 RAM claim to make overclocking even easier by automatically detecting the appropriate speeds and timings for your motherboard, making these modules “Plug and Play” ready. Arriving in 4GB, 8GB single, 8GB dual or 16GB dual-channel kits, the Fury line will have frequencies of 1333 MHz (CL9), 1600MHz (CL9), or 1866 MHz(CL10).
