I am a little wary of posting this as I have just found out that the memory I purchased after asking for a build on these forums might infact not compatible at all.

I was hoping someone who KNOWS these would help.

I ordered:

Asus M4A79XTD-evo and these:

Not knowing what I was doing and hoping people could help me, obviously people are giving answers without even knowing themselves and I would like OC to be aware of this and other posters to be wary also.

I have been having problems with games restarting/driver/Time out detection and recvoery and 'AMD Northbridge' crashes. Many troubleshooters point to the memory which promted me to look into it.

i was hoping that someone could give me some advice. I have tried the gskill forums, which are useless so far as i am registered but can not post.
 
Hi there, Have you set the RAM frequency, voltage and timings manually in the BIOS or are they running at default settings?

Also, did you go for the two stick or four stick kit?
 
Ah, well I think that may be your problem. Enthusiast memory is rated to a certain level, but the way the BIOS works it will automatically set the speed/voltage/timings to a (lower) default level. Hence you need to go into the BIOS and input the correct memory settings manually.

I would suggest you familiarise yourself with your motherboard manual (specifically the memory section) and when you feel confident set the DRAM voltage to 1.6V, the timings to 8-8-8-24 -2T (CL- tRCD - tRP - tRAS - command rate) and frequency to PC3-12800 (ie 1600MHz effective).
 
Thank you so much for that.

I will have a gander through my manual. I have been through the BIOS afew times so the look of it is not so fightening :)
 
Well I had a go.

I am here posting so at least it booted!

They only problem I encountered was that the Frrequency will only accept : (AUTO) (800) (1067) (1333) or (1600).

I chose (1600) which assumed was the same thing.

CPUZ is currently showing

NB Frequency 2000.0MHz

DRAM Frequency 800MHz
FSB:DRAM 1:4
CL=8.0 clocks
tRCD=8 clocks
tRP = 8 Clocks
tRAS = 24 clocks
tRC = 40 clocks
CR = 2T

'SPD' says Memory slot selection
Max Bandwitdh PC3-10700H (667MHz)

Does this look about right?
 
Generally the safest way to select memory if you don't 'know' is to firstly go to the Mobo web site as they usually have approved memory listed. Secondly go to the memory manufacturers site and use their selection tool which most have.

The advice on these forums is usually pretty good but you must still use caution.

Andi.
 
Yes, thanks i found all this out when looking bits up.

The f3-128000 is in the list but.. will see how it goes.

CPUz said the freq was still 800MHz - is this simply becuase I am not using much or is something still not right?

Yup - looks like you did it right :)

Where it says "DRAM Frequency 800MHz", this is the actual frequency. However due to DDR (Double Data Rate) where data is transferred on both the rising and falling edges of the clock - the effective clockspeed is double this. Hence your memory is currently running at 1600MHz (effective) clockspeed - which is exactly what you want and a fair bit faster that it was running before (most likely 1066MHz).

Don't worry about the SPD tab - that is just the presets.
