DFI Expert, Dual Core and Dual Channel = 3DoD

Recommended Posts


I wanted to find people that have a Dual Core, Expert and are 2x prime stable with 2x1024mb (or even 2x512) of any kind of ram.


Please list:

-Mobo: (Expert ONLY and revision if you have it)

-CPU: (dual core's only plz and revision/week code/etc if you have it)

-Memory: (dual channel only plz, 2x1024 or 2x512 and slots)

-Bios rev:

i have similar probs with my expert board. Thank goodness i read this post before making another unnecessary one. I am running the following rig. I could get it to POST but i cannot install windows. Let me try moving it to the orange slots 2nite and see whether that helps. Current it is in the yellow slots. I am using 2 x 512 MB G.skill 4800FF.

Hey Knob,

I'm don't remember if I have posted here about this but when I first got me Expert I had the same exact problem. I could post and get into BIOS but as soon as I started to load Windows it would freeze up and just stay at the first screen of Windows loading. I hate to admit it but I tried everything for two whole days and I mean everything. Different BIOS versions, I built, rebuilt, and rebuilt again my RAID Array, tried different HDD's, unplugged everything but CPU, graphics card, HDD and keyboard and nothing helped. Then two days later when I was completly bummed and ready to RMA my board I decided to swich my single 512MB TCCD modules from the first yellow slot (Furthers away from CPU, to the first orange slot. Well I couldn't believe it, Windows started loading. I was so happy even though that probably should have been one of the first things I did! Keep us posted on your progress!

and swapped in

2x1024 2 3 2 5 OCZ EL Plat 3200 2.8v (good to about 250fsb 1:1 when paired with the 3500+)

I had my 3500+ in there previously with my 2x1024 2 3 2 8 OCZ Gold 3200 sticks...which was great up to about 230. The highest i tested it with prime was mem bus 225 on a divider, sitting around 2.7ghz. (Chk out my link it rox my sox =D i'm such a dork)

Anyway, i had the 3800+ in my asus premium board, and i'm using the dfi (or i'd like to heh) as my main now, so i swapped it over...To the welcome of a DFI 3 dot memory error of death... So, I left just one in the 3rd slot...orange (going away from the cpu) and it booted fine. I rebooted and tried the same sticks in the same slots again. 3 dots. So i reset the bios, rebooted... 3 dots... took the first stick out of the orange slot (closest to the cpu). Booted right up. Tried extra voltage with 2, tried less, tried more on the cpu...tried combinations...Tried different timings...different dr str's and max latency and read preable...Then i tried the yellow slots. Booted right up...And bsod'd windows, corrupting the boot disk. Woot. Thats when i began crying. So i went back to one memory stick, and repaired my windows boot files...booted in to windows without issue (1 stick in). Then i brought down my 3rd system, an epox something or other which had my ocz 2 3 2 5 ocz el plat 3200's in it. And swapped in that memory (2x1024). Same problem. I didn't try everything (notably not using the yellow slots again...grr), but i retried everything i could think of.

I have some ch-5 2x512 and some 2x512 tccd i could swap in if you guys want...for testing.


Original Thread

DFI Expert, OCZ EB PC4000 platinum and DualCore


I've just gotten a DFI expert board, and can't seem to get my ocz eb platinum pc4000 sticks to play nicely with my dual core

when i first set up the expert, i flashed to the latest official bios, put my memory in the orange slots, plugged in an opteron 146 and everything was great. it booted up and allowed me to overclock quite easily

my problems started when i swapped the opteron for an X2 4400. at first it wouldn't boot , so i tried swapping my memory around in the slots.

eventually i found i could only boot with a single stick of memory in either of the furthest slots from the cpu. so using a single stick i tried to set up the timings and voltages, exit the bios, turn off the pc and insert the second stick.

no matter what timings or voltages i use, the pc either hangs with 3 red leds lit, or tries to load windows, but stops on a blank screen (or a faded windows loading screen)

after about an hour of playing with the memory settings i found it will boot with both sticks in the yellow slots if i set the command rate to 2T

i've tried OCZTony's settings for these sticks (nice relaxed timings) in the expert board, but it will not boot unless i use 2T even at 200MHz

i have previously had these sticks running at 255MHz 1:1 at 1T with this same CPU in an SLI-D board, and this is kinda baffling me

what could it possibly be???

and help, tips, or advice would be really appreciated, as i am losing a lot of performance running like this

I've running my sig system with no probs.

When I first set up the system I left all the mem settings in Auto/Default. No probs on initial boot with those settings.

If all your stuff works flawlessly in another board.............

I was running a single core then upgraded to an X2 myself. I had to up my voltage to run stable. What I can see in your post is your running at 1.32 volts, try upping the volts to 1.400 with a 110% above and see how it runs. I had to set mine to 1.450 with a 110% to get my OCZ PC4000 running smooth.

I should have a 3800 X2 to play with this afternoon. I'll see what I come up with and post back in this thread.

-Mobo: eXpert (original BIOS)

-CPU: AMD 64 Athlon X2 4400 (sorry, no at home)

-Memory: G.SKILL Extreme Series 2GB (2 x 1GB) 184-Pin DDR 500 (PC 4000)

-Bios rev: stock BIOS

-Timings/Voltage: (sorry not at home, but mostly stock)


Err, sorry, not much info for you there. I am running at stock for most everything with no tweaks or updates (to hardware), but this definitely says something about the situation. My eXpert seems to love my dual-core and my G.Skill dual channel memory, without any teaking what-so-ever.

Sorry for the lack of details on my settings, but if a setting was changed, it's in my sig. Everything else is default settings. Dual Prime stable for 10 hours; original BIOS.

Never had a problem using HZ, EB and Redline memory with 165/170 Opterons in my Expert boards.

Thx for the responses. It's good to see that not everyone is having problems. Helps me think/hope i can fix it myself.


Do you have any suggestions? I've spent days working with this bios with my 3500+, but it won't even boot at stock (after resetting the bios) with either 2gb set i have with the 3800+ x2. I'm currently running with 1 stick in the 3rd slot at stock timings and voltage. And i'm at work right now so i'll have to wait until i get home to fool around with it.



(and i went through the database and linked the one that had a dual core on a expert...that was one of the first places i looked before making this thread)
