Question 1

I am also wondering if these will work in a ASRock motherboard - the Z77 Extreme4 LGA 1155? could  I install two sets in this board? I didn't see this memory on the Memory Support List.

Accepted Answer

I've checked the supported memory list.  2133 memory is supported for this motherboard, but it is overclocked. This means that there's  a chance of overheating the motherboard and CPU under load.  This should not be too much worry since most motherboards automatically downclock memory to acceptable speeds, and if not, you can manually change it in the BIOS.  I'd recommend using this puppies with a good cooler like a Hyper 212 Evo or Hyper 212 plus and there should be no trouble at all.

Question 2

Will this work with an AMD Processor?

Accepted Answer

Yes, be sure to check the processors specifications, it will list the maximum RAM speed, the processor i purchased the A10-6800K accepts the 2133 as the highest speed, some may have a lower max speed it can work with. Hope this helps... I do like Ripjaws RAM, I use on my other AMD system and have never had any issues... also be sure the motherboard supports the specific ram speed as well

Question 3

Im running on ASRock Z97M-Mini ITX Mobo, for some reason, windows shows that there is 8GB memory installed but only 3.47GB is useable. 
Anyone know whats going on?

Accepted Answer

This may be indicating you are only using a 32-bit version of Windows. To determine the OS system type, go to the control panel, and double-click 'System'.  The difference between 4 and the amount available indicates an integrated graphics card is also being used.  Please verify.

Question 4

I have 8 g of ddr3 pc1600 memory in my computer. Are they compatable with each other?

Accepted Answer

You end up with the lowest common denominator. pc1600 might be able to OC but I doubt it will OC with the other ram on. Whether the mb or the pcu can handle it, the practice has always been (the 30 years I know of that is) the machine slows the faster ram, or everything crashes.  Depending on your OS, (64 bit windows?)16 gig at 1600 may be noticeably faster than 8gig at 2133.  Just remember where you dock your memory when prices go down and you get around to upgrading.

Question 5

Trying to get 2133Mhz, I have Gigabyte 990FXA-UD3, when I enable XMP profile, it fails, boots up to 1600Mhz back. Anyone knows how to enable 2133Mhz on this motherboard?

Accepted Answer

double check your ram slots... sounds like you installed the sticks in single channel mode.  Usually the dual channel mode is slots 1 and slot 3.  or 2 and 4.. I hope this helps..  other wise I have the same ram and its xmp profile works perfectly fine.

Please let me know if it fixes your problem....

Question 6

I'm trying to find out if this memory is compatible with Intel 3770k and the ASRock Extreme 4 mobo....i am buying this memory from a friend while I'm in town, he says it will work, but I want to make sure....I mean what is the difference in memory for Sandy-bridge vs Ivy-bridge?

Accepted Answer

It is compatible as that is what I am using now, Just remember to go into the Bios and set is speed to 1600, As it is not recommended to not use the 2133 speed with the processor ((THat is unless of course you overclock and processor life doesnt matter as much) then go ahead and set it to 2133.

Well this is my thoughts as I am using it right now so no problems with it.

Question 7

is this ram compatible with amd richland apu?

Accepted Answer

The processor and ram don't necessarily need to be compatible, it's more based on the motherboard you're putting them in. The motherboard must support PC17000 speeds, otherwise it will only run as fast as your motherboard allows. Make sure the socket type on the board matches your processor as well.

Question 8

Will this work for p67a-gd80 (b3)?

Accepted Answer

That ram will be great on that board.  When looking at mem compatibility on motherboard just make sure native mem voltage is supported as the mem controller now resides in cpu.

Question 9

Is this compatible with AM3+ board to clock to advertised speed?? what motherboard? planning to hook up with FX-9370

Accepted Answer

I used it for ~2 months in my HP Pavillion 500 (A8-5500 class) before transferring it yesterday into it's new home:  A Gigabyte 990FXA-UD3 running an FX-9590 CPU.  Runs like a champ (But I do not Overclock)

Question 10

I am planning to use this ram with the ASROCK fm2a75 pro4-m motherboard. I don't know if this motherboard will put out 1.6v. Will this ram run at 1.5v? Could I can adjust it in BIOS? If so how will it affect its speed?

Accepted Answer

I have been running mine at 1.5 for about 2 weeks and yes I do not get 2133, but 1950+. You can get more out of it later if you replace the motherboard, but for now it's better than 1866.
