Hey guys.
So i've been looking into a problem with my pc that may be related to the RAM, i have 8GB (2x4) or Samsung Green DDR3 RAM in Dual Channel on my rig, and every time i run a MaxxMEM test it shows a Memory Latency of 150ns, and from comparisons to others this shouldnt be the case?
I run an i7 2600@ 3.4ghz, GTX 680 2GB VRAM and a z68xp-ud3p Motherboard.

Is there any way i can reduce this, i believe all the voltages are on Auto so that may be the problem? This might fix the problem i've been having with Micro Freezes in games when things are loaded (as the SSD never fixed this issue)

Many thanks!

are you running the ram at stock speed/volts/timings?

you might be able to run 2000mhz im not sure on that board as gigabyte did update the bios's to support that ram better

you should be able to run 2000mhz and 9-10-10-21-1t timings and set the dram voltage to 1.55v

faster ram speed/lower timings will reduce latency

Hey Wazza, something i noticed in my testings.

So i set the timing to 2133mhz and upon rebooting i did a test, it was down to 45! But i notice every time i set the Priority in the options the RAM selection dissapears and goes back to being high like that again, so i just dont change the priority in it.

My computers running 2133mhz just fine. But it didnt fix the problem, i think its just down to how Payday 2 loads, gonna test Left 4 Dead 2 see if it helps, fi not i have no clue :/
 
it should lower it,if your running higher ram speed,no matter what games you run ect

check in cpu-z spd tab to see that its being applied,sometimes it wont apply the setting in the bios so you have to reflash the bios again so it will apply
 
did you set the dram voltage to 1.55v?

might need 1.65v dram but im only using 1.55v with my gigabyte board

Ah i didnt actually do that, i'll go back and try that in a bit.
I'm assuming a lot of the problems i'm getting arent related to the RAM though, no problems ever show up in memory tests and such, and i've never had problems too bad, just some games seem to stutter when things are loaded from the HDD, most notably Payday 2, left 4 dead 2 only freezes for like .5/1second if i set paged pool memory to High which made me believe it was a fault with the RAM so i'm not entirely sure.
 
what hdd you using? it shouldn't be ram causing the stutters

you have an ssd at all? might help to have the os on that and games on your 2tb hdd

but yh id expect some stuttering if loading from a hdd

try with 1.55v dram voltage,it shouldn't crash then
 
I noticed the stutter on Payday 2 was reduced a lot to near zero when i was running Low textures on Payday 2, but my graphics card should be able to open that game up no problem!

Yea my OS and problematic games are all installed on the SSD
 
You could try a mild oc? Not sure if stock CPU speeds would bottleneck anything,can try a 104 CPU/pci clock
