pls show ur bios template (bios settings). so dat people cud figure & rule out wat settings shud be done in order 2 achieve 1066.

Added on October 17, 2009, 4:58 amim wondering why it shows my ram pc2-6400 in cpu-z(in fact my ram is pc2-8500),of course if it show pc2 6400,means the mhz only 800mhz and i can only get 1:1 if my fsb is 400mhz.This is the cpu-z :


sorry,how to get clear image?

Added on October 17, 2009, 5:16 amafter u disabled the C1E and CPU EIST,then LOAD OPTIMIZED DEFAULT.
then cpu-z will recognize your proc speed correctly as what i've done.

sorry to budge in
but do gigabyte have "r-comp" setting for rams?
that should be the crucial factor in p45 series motherboard

what do u mean by r-comp setting?
can elaborate for me?
cuz i have some problem with my ram.

have try using different strap (MCH latch)? try use 333/200.

do u mean that i need to change this?---> System Memory Multiplier ..............: 2.00D (D for 400 strap right?)
do u have any recommendation to get my ram to 1066mhz?
sorry,im still learning for ocing.
btw thanks

just change ur MCH Latch to 333/200 and try different multiplier. but honestly, 800mhz and 1066mhz is not much different. not that u can notice the different.

me myself use strap 400 and running ram at 900mhz 1:1 divider.

no updates? got beta bios..no official release yet..

turn on load line calibration and reduce vcore... improve system stability, save power and no performance drop

im using EP45-UD3R too... love this board alot... its a very very good performer
the only bad thing is 1 PCI-E X16 slot... now i hunting for 2nd hand UD3P XD

(WTS) EP45-UD3R
(WTB) EP45-UD3P

heheheee

what for sell? just get 5970 and u're good to go! 5970 even pawn GTX285 Sli.

im using ep45 ud3r, q6600, mushkin pc6400, gtx275, odin pro 550w.

last nite, theres a lil bit of short circuit. then my pc went blank and ownt start.. its like this, switch on, the psu run, and all fans will work, but no display. and after around 20-30 seconds, it will auto shut, and auto start again.. all fan will keep working yet no display at all.. i suspect its the psu..

Btw, gigagyte have 3 years warranty rite? how long will RMA takes?
ive posted this in technical support, pending for reply.

tq all

did u OC ur rig?? sometimes not enough vcore will make that happen, where rig 'on and off' and keep on looping.

if not, clear cmos then see. if still happen, RMA is the way to go...

tq for the reply..yes, i did OC my rig.. now i can boot, but my ram slot 1 and 3 is faulty, other than that seems alrite..should i send for RMA? the age of item is less than a year, can get 1 to 1 exchange rite?

i'm using ep45-ud3r now.. just want to ask.. it's good or not to update the bios ? currently F9. the latest one F11?

other Q..
why this board only read my 4gb ram only 3.25gb..
before using ep35-ds3l detect 3.75?
confuse here... or it's normal?


after update the bios...to F11 tonight..
the good is.. my ram already detect 3.5GB...
which is good for me...

about u question... its u operation system(windows) 32bits... if yes... 32bit just detect u rams at 3.25gb onli....
if u take 64bit.. u can get full ram..
about flash bios... they give warning because flash bios can make u system running malfunction...
if dunt have any problem with u old bios.. the good is use it ... i update my bios ... now f10..
enough as long dunt have problem..

i just brought ep45-ud3p... support crossfire ....
i check compare with ep45-ud3p and ep45-ud3r..
got 3 different..
1) ep45-ud3p = got 2 gigabyte lan with teaming ( ud3r = just 1gb lan)
2) ep45-ud3p = got TPM for more security database(ud3r = dunt have)
3) ep45-ud3p = support crossfire(ud3r = just 1 slot pci 2.0 Express x16)

got 3 different ep45-ud3p and ep45-ud3r..
so far... using it .. very2 easy to overclock.. e7400 also easy reach 4.2ghz overclock

yeah im using ep45-ud3p too for a year already.good to overclock even for beginners noob like me of 1 month oc knowledge catch up currently oc on my q9400 3.60ghz with 1.300 vcore 8gb ram makes me squeeze harder on more MCH voltage ram volts as well...indeed there's 1 more 4th difference if i not mistaken that is the dolby surround output sound or something to do with that right..too bad it didnt get me to use all the 3 benefits since im on 1 piece 4870 graphic card, creative sound blaster audigy and all those TPM stuff didnt touched it at all b4 lol
