Asus Crosshair IV Formula + G.Skill Eco Cl7 Problems!

[AraS]

Hi , there

I have Asus Crosshair IV Formula with Amd 1090t & G.Skill Eco 1600mhz Cl7 7~8~7~24~2t , I have problem running memory at rated speeds.

The memory works only at 9~9~9~24 1600mhz , anything bellow i get Bsod ,

i tried switching memory to different slots ,i tried cpu&nb voltage at 1.2 still the same . is it duft ram or something i can do about it or it rma time ?

Ta for help

Hello, let's see if we can help you.
I'm also the proud owner of the Crosshair IV Formula and 1090T.
Is your set 2x2GB or 2x4GB modules?

If your running the 2x4GB set (8GB total), then you may need to increase the NB voltages.

Try these settings if running 8GB or more:

CPU/NB voltage: 1.30v (up to 1.35v)
NB voltage: 1.35v (up to 1.40v)
NB 1.8v voltage: Auto (for now)

Make sure you monitor your NB temp when running stress testing with these settings.
Some of the original Crosshair IV boards shipped with a loose NB & SB heatsink.
ASUS has since corrected the problem on newer releases (with bios 0905 & above).

no im running 2x2 set , also there no need of Nb voltage that high , and im not sure how it would help memory, my NB is at 1.21v 2600mhz stable.

waits for g.skill staff or moderators to help.

[NemesisChild]

Yes it does matter, the Phenom CPU's have an Internal Memory Controller (IMC).
So the NB frequency and voltages will have an impact on memory stability.
With your NB@ 2600MHz, I suggest increasing your CPU/NB voltage to 1.25v.

[AraS]

just tried it same thing cpu&nb at 1.35 nb @ 1.25

[NemesisChild]

Try CPU/NB voltage at 1.275v, you shouldn't need it any higher for 2600MHz.

[AraS]

Try CPU/NB voltage at 1.275v, you shouldn't need it any higher for 2600MHz.

same thing i told you it is not thing to do wit nb volts , well if nobody else have any ideas i will burn memtest today and test it and if it fails it is RMA time i guess.

[NemesisChild]

I know I thing or two about AMD builds and the Crosshair IV.
If you don't want to take my advice, then fine, that's your decision.
Since it's apparent that you know so much more about NB voltages and such than me, I will offer no more advice.

Good luck...

[AraS]

seriously you think it needs 1.3v at nb volts , then that memory would not work on any amd motherboards tbh , even with 1.3v it bsods its clearly not that. you cant offer me advice as you dont know what to advice anymore as i checked everything what is suggested.

[Tradesman]

For what it's worth the AMD CPUs have weak MCs (memory controllers) and generally need voltage tweaking for the 1333/1600 speeds on up. 1.3/1.4 NB is not at all unusual

[AraS]

tried from 1.3v to 1.4v doesn't even boot to windows straight away bsod

[GSKILL TECH]

Back it up, this motherboard/CPU may require 1.45V-1.50V for this memory.

First, set memory to DDR3-1333. Raise CPU Frequency to 240 (from 200). This will overclock the memory to DDR3-1600.

Then set timings to 7-8-7-24. DRAM Voltage 1.45V. Then let me know how that works.

Thank you

looks like its more stable now i will do some more testing.
