Is there something wrong with my ram?

[hunkeelin]

well as my rig stated, my ram is

g skill z series 1600 (12800) 32gb kit quad 9-9-9-24'

however for some reason when i open up my cpuz and check my ram.

i get these

dram frequency: 800mHz
latancy 11-11-11-28

isn't my frequency should be 1600mHz and my latency should be 9-9-9-24? am i missing something here?

The frequency is right, your ram does not operate at 1600MHz, it operates at 800MHz but uses clock signal tricks to maximize the data that can be transfered in each clock cycle.

The timings are loose though, the 11-11-11-28 is what your BIOS has implemented, you could go into your BIOS and tighten the timings to 9-9-9-24 if you wanted.

The BIOS won't always implement the specs for the ram. Often times it is up to the end user to do that.

cant he just select the XMP profile in the BIOS? that should make it run at the advertised settings.


EDIT: speaking of which, I have a question about that. in CPU-Z under the memory tab it shows my ram as 9-9-9-24 like it should be but under the SPD tab it says my XMP profile is 9-9-9-25.

That's funny, my G.Skill is showing that, too.... Off to the BIOS we go...

EDIT: XMP did indeed fix it!

Just be careful when enabling XMP in the BIOS because not all mobo makers adhere to implementing the SPD settings verbatim.

For example, my ASUS MIVE-Z, if I enable XMP in the BIOS then it will change the Vdram from 1.5V to 1.65V automatically.

The thing is, 1.65V is not in the SPD for my ram, my ram isn't even spec'ed for 1.65V operation (its 1.5V spec'ed at all SPD and XMP settings), and of course my Sandy Bridge is also spec'ed as not being ok with 1.65V.

Yet my MIVE-Z bios will just go and set it like that if I don't watch it.

So can anyone teach me how to tweak my bios so my ram is on the level i aspected without causing any trouble? ('im really new) i know i have something call the dram memory control where i can just change the latancy manually, but as Idontcare stated it can be dangerous so what's the safe way?

For some reason, sometimes BIOS won't set the RAM at correct speed & timings & voltage, it happened to me on a LGA775 system, where the RAM (DDR2) was suppose to run at 2.2V, but the BIOS would set it at 1.8V (everything auto) and cause all type of system instability.

 

[hunkeelin]

yea ok. so how can i set back to the latancy i expected without causing instability?

Have you tried enabling XMP under A.I. Overclock in the BIOS?

 

[hunkeelin]

how to do that d4a2n0k

 

[d4a2n0k]

Go to the "A.I. Tweak" tab in the advanced BIOS and simply change "A.I. Overclock Tuner" to X.M.P. That *should* automatically load your RAM settings but as mentioned above, it sometimes does not work.

 

[T_Yamamoto]

make sure it doesnt automatically change voltage to 1.65

 

[birthdaymonkey]

And if it doesn't work, you simply enter the values manually...
