btw, dark knight doesnt use copper. DK uses fully nikel all over its heatsink . and sad to say that according to frostytech, the performance is poorer that S-1283

anyway this thread becoming air cooling thread edi

use nickel for the whole heatsink?? not just coating?? they are just cutting down on costs and also unfortunately performance with it..

i know nickel has a very low heat exchange. about half of copper. not great at all..

something like the asus triton or something that has the gold cover, it's expensive but performance wise it's way way unsatisfactory.

i observed it too, my mobo sensor detects only 1100+ rpm only , the box stated only able run 800-1500rpm ,and the rear fan i put another Xigmatek XLF-F1253 FAN , mobo sensor detect around 1500+rpm ,it will cause the heat stuck on inside? and should i get 2000+ rpm fan to get better air flow??

the back casing fan you put exhaust or intake?

depend whether what position you put your heatsink. horizontal or vertical??

i put my 1284 horizontally and blow air upwards. i have another 2 top mounted casing fan for exhaust..

can ifx-14 fix this board?

i'm not so sure.. try asking ham_revillo...

that heatsink is quite big..

yup you can . although the cooler looks gigantic but it provide enough clearance from the board's mosfet cooler and north bridge

anyway here is some result too (look at post 327):

yeah...understand.. high enough to pass ever the mosfet and northbridge cooler..

Hi, new EP45-UD3R user reporting in.
The mobo is awesome. Good OC and cheap. This is similar to Biostar T-Power I45.

My oc result 4.4GHz on air cooling. Low FSB due to air cooling.
OC result validation at my siggy.

haha, i just got the EP45-UD3P also..
really awesome board for quadcore
some testing..

510fsb


500fsb pl8


500x8 4ghz ibt past

I see my old Q9450 in action..

ncie result hengmy

ape bende u adjust kat bios?

will Sunbeam CCF/Deepcool Killer whale/Ice blade pro can fit this board ma??

between these 3 coolers wich one is the monster??

Your core temp is quiet low, wonder whether u are inside a/c room, if not what heatsink r you using.

thx so much bro

thx, i adjust all those setting inside bios that can adjust, it easily can boot at 500fsb, but to stable it need to adjust those GTL REFs.

it idle on air con room, i am using TR IFX 14

hmm...u mean adjsut the cpu REF?

that one so many value i saw in my fren's ud3p... if trial and error adjust till sienz

ya, i must adjust the cpu ref to get it stable, if leave it auto, it cant pass prime or IBT.
i use this formula to count, but i dont know it right o not.
it default 0.76/1.2vtt=0.633(45nm)
i set cpu vtt to 1.34
so 1.34x0.633=0.848 ~ 0.84-0.85
btw, i using F4 bios

after adjusting, i can prime almost 5 hours

Trial and error
Got to have a lot of time at hand lah

Sunbeam CCF CANNOT fit the mobo..try looking back a few pages..you'll have pics for that.

get a s1283 or s1284 xigmatek

@hengmy
hi bro.,can u share the bios template with us..tq
