I need help with my ram

[asung415]

Hello, i am new to the forums

 

My problem, is that whenever i set my ram frequencies, above 1600mhz, post only shows the stick that is in the first slot. But the wierd thing is that if i go into the bios, the spd information will show all sticks of ram, any help?

[Godlygamer23]

What do you mean POST will only show the stick in the first slot?

[asung415]

so if i have one 4gb stick in the first module, it will only show 4096 as usable, vice versa, if i have the 8gb stick in the first module it will recognize 8gb 

[asung415]

I told ASUS about my problem, and they told me to use xmp profiles, but that is only for intel, so i was stumped

[Godlygamer23]

The way you describe it...it's normal.

[asung415]

so you are saying i cant have my ram above 1600mhz? or should i pump more voltage? i know 1.65v is the max for the 990 chipset

[Godlygamer23]

Well, you're saying if you have one 4GB stick in a lot, "only" 4096MB is available, and if you have an 8GB stick in the first slot, you have 8GB available.

[asung415]

but i still have other ram sticks installed at the same time..... sorry if i wasnt clear

[Godlygamer23]

You may have to RMA the board, or the RAM

[asung415]

Good old RMA...

[Godlygamer23]

You could also try using the memOK button if you have one. (chances are you do)

[asung415]

Oh the thing is if i do press the MEM ok button, it just reverts the setting back to the default (1600mhz)

[Godlygamer23]

RMA the RAM first if you can.

[ProKoN]

what ram are you using?

 

speed, capacity,brand?

[LogicalDrm]

So you have two sets of different size ram sticks? something like 2x4 & 2x8? or just 8 and 4? That also could be issue. But if bios and windows show it normally I don't think it's gonna be end of the world.

 

E: whats your mobo? Does it even have support for ram clocks over 1600?

[asung415]

Yea i have 2x4gb, and 1x8gb, and I have the asus sabertooth 990fx, so it does support above 1600mhz

[asung415]

what ram are you using?

 

speed, capacity,brand?

2 sticks of 4gb g.skill sniper series ram, and one 8gb stick (patriot memory)

[Torg73]

you checked the G.Skill duel memory kit is the same speed as the single 8gb Patriot, that could cause problems when over clocking even tho its stable at stock speeds.

[sotiris.bos]

Are you sure that all are rated for 1600Mhz or above? What about the timings?

[Torg73]

have you checked your memory is in the right slots, I know this sounds strange but if you put a pair of memory in the slots on the motherboard but they are not in the right pairing it could cause the computer a lot of problem's.

 

Most motherboards are colour coded with the the memory slot's, on my motherboard I can have 4 memory slots, 2 are black and 2 are gray, if I put my 2 memory in say 1 in the black one and in a grey one, it should work but there could problem's later on when I over clock my cpu.

 

so make sure your memory is in the right slots.  on most motherboard's today they have 4 slots, and numbered 4 -2-3-1, you should populate slots 1 and 2 together with a pair and 3 and 4 with the second pair of memory or put a single memory chip in slot 3.  You can see the number on the motherboard, it can be small but it should be there.

x58 and above is very picky on ram. Could you have them run to the default speed \ timming?

 

also take all of the off, blow into the slots and the rams , Use slot 2/4 or 3/6

Are you on 32bit or 64bit OS? Are you on Intel of AMD platform? More information would be nice. If you are on 32bit that is a normal problem and some limitation of 32bit OS if you are on 64bit then shut down your PC, discharge all static electricity from your body and then try reinstalling your RAM then go in to UEFI/BIOS and make sure that all dimm slots are turned on.
