About ram 2666?

[Ser Superior001]

hi, i have the the same question as him 

 

but the diff is that i have 2 ram slots ddr4 kingston hyper x fury black 2666mhz(hx426c16fb2/16 is the part number in cpu z) so i have 32 gb ram in dual channel, but the problem is i have msi z170a g-45 gaming motherboard and is not the

 

2666 mhz support:

 

3600(OC)/ 3200(OC)/ 3000(OC)/ 2800(OC)/ 2600(OC)/ 2400/ 2133 MHz

 

will i damage my pc??

 

also i cant find hx426c16fb2/16 in google, it does exist??, how i know my ram slots are genuine and not a falsification/bootleg??

No, it won't. 2666 MHz is a JEDEC standard mode, so it should always be supported. The ones that are listed are all Overclock (OC) modes for the memory. If the CPU's memory controler doesn't support a specific mode, it should simply fall back to a lower JEDEC mode instead.

The /16 at the end simply means it's a kit with 16 GB. Search for "hx426c16fb2" instead.

No, you won't damage the PC by doing this. It's technically RAM overclocking because the 6700K is only rated to support 2400MHz, but at the same time a 6700K can run upwards of 3600MHz without much of a fight. And no, this won't damage anything, the worst case scenario it would be a little unstable, but as said before that's not gonna happen with a speed as low as 2666MHz.

It works right? That's all that really matters. I wouldn't really worry about it.

im testing the pc right now, i hope are genuine and not fake.

 

but my motherboard dont mention 2666 in both stock or OC cases, are you sure i wont have any issues?

If you want to know what's guaranteed to work with your machine, search your board manufacturer's QVL list for RAM certified to work with your motherboard. I've gone through a ton of aggravation and wasted time and some wasted money because I didn't know that was a thing. I did a write-up explaining it...

and how i know my ram is genuine?

I'm still not exactly sure what you mean by this. Why do you think it's not real?

i mean how i know my ram is not a fake ram (bootleg, chinese etc), how i know is a genuine kingston hyper x black fury 2666mhx ddr4

You won't have any issues, no. 

 

Source: Own a Z170 board (OC Formula specifically) and a kit that supports 2666MHz JEDEC, it always just boots at 2666MHz and runs completely fine. 2666 is not mentioned in the support page.

I'd be very surprised if it was fake. The model number sounds like a standard Kingston model number, I've found many similar models (they have 1-2 numbers/letters differently). It's probably just a more obscure kit that the data sheet is harder to find with.

This is a 6 year old motherboard and CPU, any kit on the QVL will have been discontinued at this point or redesigned (new PCB, new memory ICs, etc.) that it's pretty much pointless.

oh sht, the rams case says hx424c15fb/ 16    16 gb ddr4 - 2400 cl17 288 - pin DIMM, wtf the case is wrong

As @RONOTHAN##said above, the model # when searched up appears to be your standard Kingston ram.

[Ser Superior001]

another thing, i cant on the xmp profile in the bios idk qwhy, cant put the mhz too 

[Ser Superior001]

case says 2400 but i have 2666 wtf? kingston's  mistake?

Maybe not. It's still a good reference for what is known to work, and just because a particular kit might be disco'd doesn't mean you can't find it used. Sometimes you get lucky and find some that was never sold, still new in box.

Probably 2400 base, overclock to 2666 with DOCP / XMP enabled. Pretty common. Also check to be sure such overclocking is acceptable for the machine. If enabled, you might check the timings are correct, if there are any specific ones prescribed. DOCP and XMP don't always get the timings right on their own, requiring manual settings. I ran into that on my 5900X rig. It was giving some wonky 20-20-20-43 timings instead of the 16-18-18-36 the board called for.

and how do i set the timings manually?

xmp is off in the bios, i cant turn it on

I would say if your machine's max (2400 in this case?) is less than the DIMM's 2666 Mhz rated speed, it would probably still run at the lower speed. But there could be stability issues, minor or moderate. Then again, there might not be any issue at all. If it runs fine without crashing or boot issues, I wouldn't worry about it, but it can be a thing in some cases.

There will be options for this in the BIOS setup menus. But you only really need to mess with this if DOCP / XMP don't get it right for the machine. Since XMP is turned off, you probably don't need to mess with this. And it's best not to if you don't have to.

damn i dont know if is safe

Just to clarify, you have 2666 Mhz DIMMs in a machine limited to 2400 Mhz, correct?

 

If it's not crashing or having other strange issues, I wouldn't worry about it too much. As long as the voltage and timings are right, speed generally has no effect on anything but performance. In this case, the machine can't run the RAM at its full speed, so if anything, it actually might be more stable as long as the timings are right, and the lower speed might even let the RAM run a little cooler. Assuming it isn't creating boot or crash issues, that is. Are you experiencing anything like that? Random blank screens, refuse to boot at times, etc.?

And this is in regard to what? A GPU question?

Oh, wait, I see now. My bad. Your PSU isn't a major factor here as long as it works properly with sufficient wattage output for the components. Voltage in regard to RAM is the voltage given to the DIMMs by the motherboard, which can generally range from 1.2 to 1.35V (usually 1.35V in most cases). That voltage can be adjusted in BIOS settings along with the timings if needed. It's completely separate from what your PSU delivers.

ok, but i dont get why i cant on the xmp, and change the mhz speed, i dont know if i can manage the voltage and timings let me see tomorrow

so i wont damage my mother board?, remembe it is msi z170a g-45 gaming and says: 3600(OC)/ 3200(OC)/ 3000(OC)/ 2800(OC)/ 2600(OC)/ 2400/ 2133 MHz, there is no 2666mhz there

No, you won't damage anything. They just didn't list all the sub frequencies. 2933 would work, 3466 would work, 3066 would work, etc. As well as 2666

ok dude, but i dont get why on gods earth when i enter the bios i cant on the XMP profile, it is off and cant do anything to put it on
