View Full Version : Simple Question about the DFI AM2 590 SLI board...

does it have auto ram dividers, or can you set your ram dividers manually?
I've seen lots of results from this board, but never anything truely spectacular.
like with my Ultra D, I did 480 HTT, but I always see low HTT on this board like 300 and such, and ram dividers at like 5 and 6...
upon reading a few reviews, I cant seem to find out if there is anything in the pics to tell me if theres any ram dividers to be able to control how your ram is handled, with this board.
so is it on "Auto" always, or is it hidden under some name I can't figure out?
(I dont have the board, just looking at the latest AM2 results)

it's a normal K8 memory ratio. 200mhz is 1:1, memory divider = cpu multi unless you're using an odd multi
266mhz = 4:3
333mhz = 5:3
400mhz = 2:1
the reason you're seeing mostly cpu/5 is because in order to hit 600mhz, you need a 3ghz cpu. cpu/5 is the lowest memory divider amd's IMC supports.

just FYI
the 266mhz divider doesnt work unless your using a half multi.
from what ive read its a problem with AM2 and not the board.
however, ive been finding the ram overclocking very finnicky. anything over 2.39Vdimm, will refuse to boot.
my damn ram is holding my chip back around 2.8ghz :(
(oh and if anyone has tips for these please lmk.)

never had an issue here. then again, i have the magical holy sempron from heaven :lol2:
for higher voltages, pay close attention to drive strength. you might benefit from changing the termination resistance too, sometimes 150ohms does a lot better than the stock 75

ah there it is.
just never seen the sub menu, thats more like it.
so how is this board anyways?
here is the sub-menu to the mem dividers...

like Ozzimark said, that is all we are given. when matched up with the chart form this post:

it really paints a picture of a weak memory divider setup for AM2. the reason i float around 300HTT is because the 10X multi is easiest to work with as far as memory goes. a CPU/4 is all i ask for from AM2 but i am not sure if it isn't possible or just no one has implemented it. with a CPU/4, mem clocks wouldn't be CPU limited and make it easier for testing RAM.
as for how the board is...i'm loving it. put in the time to learn the memory tweaking and the rewards are great. if you don't put the time in though, it can be a bit un-forgiving.

so far ive been loving it. even though its been giving me some issues with the ram voltages, its hard not to love all the options you get to tweak.

i know what you mean. the lack of fine tuning with the ram dividers is really a PITA. for my slower ram its holding back my proc, but for people with faster ram, they wont be able to tune it for full perfomance.
makes me miss the dividers on my old DFI NF3 LP UT

Sorry alittle off topic, How did you get the picture so CLEAN looking?
The board performs pretty well. I flashed my bios to the newest, and I still get some crashes here and there..

yeah, the board is amazing, provided the time to figure it out. like someone said somewhere.. like a girl. awesome when you dedicate enough time to her to make her happy :lol2: (my apologies to the girls out there ;))
and.. i'm REALLY banking on AMD putting 1/2 memory dividers into the 65nm chips. if they don't, it's just stupid.. they're using the 1/2 multis anyway :fact:

haha, magic :D
its not a picture, its a screenshot. there was a tutorial about it here on XS but with the sub-forum change up recently i can't seem to find it. ahh here we go...good old search.

apparently the thread doesn't exist in a forum anymore but you can still access it through search...HTH

i was just looking into that more since you said it actually. some weird things occur. have you run sPI at 1m and noticed the times? i was getting 38s at 2.8ghz and 400mhz ram at 3-3-3.. 8.5x multi with the 266mhz ratio :wth:
