Question Is it ok to combine an 8gb stick of RAM with 4gb stick of RAM?

[PetarStev]

One stick is 1866 mhz and the other one i believe is 1600 mhz. How will thiss affect the performance of the RAM

Considering that it may completely fail to work...."is it OK" = maybe.

Mixing RAM is always a crapshoot.
Differing RAM means running in single channel mode, if it works at all.

If they do run , they will run a 1600. There is a good chance they won't.

Im running a 4gb with 2gb stick at the moment and nothing has failed

 

[USAFRet]

Im running a 4gb with 2gb stick at the moment and nothing has failed

And that does not guarantee a different config will work.

Mixing is hit and miss regardless of what you have installed currently.

So should I mix them or stick with a one 8gb stick

 

[Dark Lord of Tech]

Stick with what is currently working.

I was wondering if all the SATA ports had the same speed.

EDIT: I checked the motherboards manual and it said that the SATA 3 0/1 ports are the 6Gbit ports. I wanted to ask is there a difference if i plug the ssd into the SATA3 0 slot or the SATA3 1 slot.

 

[COLGeek]

No difference. Use whichever is most convenient.

No difference. Use whichever is most convenient.

For real? Because I checked the manual and it says that there are 2 with 6gbit and 2 with 3gbit

 

[COLGeek]

SATA 3 ports are all the same speed. SATA 2 would be slower.

Breh sorry I forgot I edited the question. Thanks tho. To be sure the sata 3 are the white ones right?

 

[COLGeek]

Yes. The white ones are SATA 3.

Should I put my single stick of RAM in the DDR3_1 slot or the DDR3_2 slot on my H81M-DS2 rev 1.0 motherboard?

 

[alexoiu]

Put it in the second, to be a bit farther to the CPU cooler.

 

[PetarStev]

So it doesn't matter in which one?

 

[COLGeek]

So it doesn't matter in which one?

Nope. Not really, in this situation. Either should work.

 

[alexoiu]

So it doesn't matter in which one?

Nope, if both slots working. However, the recommended slot is the second one.

 

[PetarStev]

Nope, if both slots working. However, the recommended slot is the second one.

The speed of the RAM is 1866mhz, but in cpu-z it says 798.1mhz. And in task manager it says 1600mhz

The speed of the RAM is 1866mhz, but in cpu-z it says 798.1mhz. And in task manager it says 1600mhz

There's nothing wrong with that. The RAM clock is half the data rate, hence DDR (Double Data Rate)

 

[alexoiu]

It's ok. CPU-Z lists DDR (Double Data Rate) speed like that (800x2 = 1600). Have you tried enabling XMP in BIOS?

 

[COLGeek]

You may need to set the speed in your BIOS (XMP profile) to achieve the memory's rated speed.

It's disabled and I can't change it. Voltage is 1.50V

Hi. So I just bought a stick of Kingston HyperX Fury 8GB 1866Mhz DDR3 RAM and I installed it in the slot. After that I booted up the PC and I checked in task manager to check the speed of the RAM. It said that it was running at 1600Mhz. I went to the BIOS to enable XMP and it says disabled and I can't enable it.
