markr: you got a PM from me regarding timings and stuff.
Sorry I didn't catch it earlier:( . Response sent. Hope it helps.Quote:

is uccc chips(bp) a good choice for this board? if im lucky i can use the 166 divider to get 3Ghz out of my chip (278mhz)
Is it just me that gets coldboot problems over 315MHz HTT ?
What bios are you on? This is a known issue with the Sapphire official bios.Quote:

NB HT Link Width is set to Auto or 16bit
RD580 HT Drive Strength is set to Optimal
HT Receiver Comp Ctrl is set to Optimal
RD580 HT PLL Control is set to High Speed
And is your HT multi set to 800 or lower?
Hi eXa. Chew* did some mem testing in this thread. You might find your answers there.Quote:

That is exactly how i'm running. Also both NB & HTT voltage at 1.3vQuote:

The data drive strength, its not in A64 tweaker or on bios?Quote:

Also got dram drive strength and can set that to normal or weak.
Cant change memory DQ thingy in A64 tweaker though, only got drive strenght (normal\weak)
Gotta try a newer one...
Edit2: oh seemes like i got the newest one... (0.6beta)
They are there. They are just not numbers like on the DFI. DRAM Drive Strength is normal or weak. DATA Drive Strength is reduced%.Quote:

Edit: You beat me to it. Try A64info. It is a sweet little program.
not familiar with dfi btw...
Downloaded a64 info. ok ditching tweaker now...
Idont think 133 divider works any good at our cpus... 133 doesnt work any good for me either...Quote:

wont boot at all! im testing the memory now. i think 150 should work (if its not borky like the 133)
Edit: 100 and 166 works fine though...
hmm what does this mean? got it on both prime but prime never turned yellow:
Torture test ran 10minutes - 0 errors, 0 warnings
execution halted
Beginning a continious self test to check your computer
and then it continues priming...
?
Edit: oh noticed now that it always says "Beginning a continious self test to check your computer" when u start priming. but why did it stop?
Edit2: eh never mind that prime thingy, everything is like normal. just a stupid user....
Ok testing 250Htt, ram 1:1 @ 3,3,2,5 right now!
Edit: Not stable, 247 was. time to reduse drive strenght thingy!
Edit2: Hmm reduced data drive strenght with 15% and prime failed @ 245htt... upped to 0% again and keep testing more @ 245htt
Edit3:Ok so redusing data drive strengt didnt do anything for me, no point in trying 30 and 50% then?
Edit4: wonder if 250 is doable with a little more voltage? upped to 2.8 (from 2,74) and trying 248now... eh no! failed while typing.
Edit5: Ok redused dram drive strength to weak. Daam, didnt help either! is it normal that both data drive strength and dram drive streng doesnt affect at all?
vell hm maybe try that P and N thing... aint that in the A64info?
Edit6: hm tried changing max async(since i cant play with P\N) latency to 9(from7) and read preample to 7(from 5.5) like ive done before and it only gave me a few minutes more in prime...
Ok what to change now? do i have to reboot everytime just to change P\N?
Edit7: Ok now im testing if i get to 295 with 166divider...
Post an A64 info screenshot so we can see timings and such.
ok. 295 went fine with 166 divider. wonder if i write down all the info from A64 and set it that way in bios, would the machine boot?
here:
YES! i think it boots alright with theese settings too! i wrote everything down and put it like that in bios and it worked! booted right up!
Think this is the highest stable performance settings ive had!
to bad 150mem divider aint in the bios or else i would had over 2.9 @ cpu!
Hmm maybe ill try the 133 divider again. change nothing but that...?
Edit: Zomg it worked!:eek:
Time to up the htt again! :slobber:
Edit2: What does "digital locked loop" does? it was enabled before but aint now! (i locked up the system and it wouldnt restart so had to clear cmos) but system booted right up after i set everything in bios again!
Edit3: Btw, how is th board supposed to beeb when u turn it on? two high and two low?
Oh and my cpu didnt like 314htt with only 1,35v. 310htt seemed fine though. Didnt test long but it usually tells me fast if something is wrong....
Edit4: Hmm @ 3ghz my memory is only at 223mhz. that should work fine with cas 2.5 insted of 3.
How does 2.5,3,2,5 @ 225 compare to 3,4,4,8 @ 278?
Edit5: Dammit! really thought maybe i could make 3Ghz with ok ram speed now, but no! since it seemes stable @310htt and not 315 i figured that all it was just cpu who wanted mor juice. so upped to 1,375. but no 315htt didnt work now either!? so im now trying 100divider on ram just to chekcj if its that (what i thought was borky) 133divider. if this doesnt work ill tri 1.4 on cpu too. if not that either.... well then im stuck!
Edit6: 100divider didnt do it!
Edit7: A little more relieved again. seemes like it needed a little more juice than i thouht. 1.4v and now it keeps going!
Edit8: Started testing 318htt with 1.4v and 133divider!
Edit9: hmm no... not shure if i managed to change the volt on cpu... I rebooted and sat the voltage to 1.4 in bios to be shure. testing 318htt now... (with 1.4 and 133divider)
Edit10: No, cant get 318htt stable. priming 315 now. Dammit what is stopping me? hope not cpu :confused: it should do way better than this!
Edit11: Daam, 315 not stable either? ran for 20min. well priming 310 then.... have to sleep, so gonna leave it at that for now. hope its still priming when i wake up!
Give these a try:
3-3-3-8
tRFC=13
Max Async. Latency=8
Tref=1032
Those settings should be good for ~250 (considering 278 3-4-4-8 was stable). If you want to tweak them better, read this thread:
http://forums.extremeoverclocking.co...d.php?t=170999
no no, i was considering buying new ram, thats where the 3,4,4,8 cam in.
My ram cant do that! only cas affect the oc on infinion chips. so i wont get higher with 3,3,3,5 or 3,3,3,8... but i could try though. But as you can se that aint my main problem anymore(i think) unless thoose other settings is what keeps me from getting past 310ht...
EDit: oh nice link, thanks. Maybe its Max async latency\read preample wich is bugging me now? will try higher there tommorrow and se if that helps!
Edit2: Dammit! not even 310 was stable, failed after like 40min. oh this got to be something else than cpu. it runs 2.7 @ 1,325 fine but not 2,79 @ 1.4.. thats not right.
Ok back to 295 with 166divider on ram (241mhz), lets se if that is stable, if so that will be my starting point....
Someone closed Titac's thread about RD580 HT O/C so I figured this is as good a place for this:
http://valid.x86-secret.com/show_oc?id=133963
This is on a production Sapphire A9RD580 that I dusted off and I am writing this message at these speeds. I just wanted to see what good ole Manta would do before taking a stab at Sturgeon (AM2). As you can see, it's not too shabby. Especially for all air cooling.
The trick here is that the async latency needs to change near ~HTT=320MHz to 8ns. After that, it needs to change again at ~HTT=360MHz to 9ns. Then again at ~HTT=390MHz to 10ns. Your results may vary, but the whole point of the board is that it has all the knobs to tune whatever you need.
It's good to see people using the boards as they were intended. ;)
