Nice job panging!! What are your MCH/Dram ref,Ch.A and B ref's set to, to get 500fsb? How did you set the clock skew? I needed 1000/1000/0/50 and OC1200. Unsure what long term use at these settings will do to the board, cpu or ram. Was the only way I could get it Prime/LinX stable.

for my DDR3 board, as of now, all of Ref. voltages are set to the same values on the left colume in bios,
and yep i've been seeing you guys use 1000/1000/0/50,
but i use 800/900/0/0 for 500fsb, above 500 to 525fsb 900/900/0/0,
i did try 1000/1000/0/0 for my 530x8.5 but later on i changed back to use 900/900/0/0.
my DDR3 board and Q9550 won't boot with any setting at NB clock skew.
and however, my system is not thoroughly tested with program like IBT/LinX yet.

for my E8400's to boot above 600fsb i used to use 900/900 and CPU/NB 200ps/100ps and sometimes i had to try using Dram clock skew.


and, for anyone's information...
the DDR3 board seems to have problem booting "500FSB strap 333 5:8 DDR3-1600" if you install your ram's on the 2 pink colours slots only,
i have not seen any problem with the green colours one.
(no problem with anything above or below 500FSB, no problem with 500FSB strap 333 1:2 DDR3-2000 nor any other straps)

Thanks, I will try 900/900/0/0 today and test it.

its my stable 4GHZ OC
is everything ok or shoould i change somthing ?

Nice info pangingIII

How do you like the DDR3 version of the EP45?

[adpr_02]

Hey guys. I've had problems with this mobo since I got it. I can't get my q6600 over 3.6ghz no matter what I try. I know I can, because my loads at 3.6ghz never exceed 50C (watercooling). So now it's time for me to try again. I've searched for posts with the Q6600 and they didn't seem to help.

Here are my settings.

Multi: 9x
FSB: 400
memory: 960mhz (PC8500 ocz platinum xtc)
Vcore: 1.5
Vtt: 1.24
MCH: 1.18
Vmem: 2.1

That's all I have changed. My goal is to maybe hit 3.8ghz and memory above 1066 stable.

could someone please guide me on what settings I should change, and how I should go about changing them? On this board I don't know what most of the things do, so I'm just randomly upping voltages here.

you should up the MCH to 1.5 Volts.. the rest seems fine.

[Leeghoofd]

For 400Mhz ? are you insane ? 1.3ish will do for sure... he prolly needs more Vcore and CPU VTT volts to stabilise it... I'll pop in the E7400 again Bluestang... currently testing a Q9550 on it... ( Thx Tones.be ) maxing at 475ish with acceptable volts... not bad for such a cheap mobo ( EP45T UD3LR) but my Micron GTR rams don't play along at all

@Lee, Thanks! I wish you were in the states...I would ship you these OCZ's to try out.

How do you like the DDR3 version of the EP45?

Hi Ghostleader, thanks.
DDR3 one is very similar to the DDR2 one, i just need to spend some time with it, and most important, seems to be, to find ram kits that can work well with the board, and if you already have a good overclocking CPU, then i would say you cant really go wrong with these boards. these boards (UD3P/R's, both DDR2 and DDR3 versions) are probably not the best boards for every needs, but so far to me, they are quite good boards. this's an opinion from just another user.

Yeah I have the DDR2 version which runs my Q9550 @ 4G no sweat. I have the DDR3 version on the way for some cold action and will be testing the max. FSB under LN2.

looking forward to your results

[Ghostleader]

thanks for the response.the UD3P ddr3 is on the because of pangingIII's results.but i'll be using a dual core so thats why i might get the RE.i hear it great with a dual.

If you gonna run dual, RE is a good choice indeed and as pangingIII wrote "most important, seems to be, to find ram kits that can work well with the board", I agree, it seem like LGA775 DDR3 board is a bit picky about what ram to choose, do some reading before buy ram.

Thanks for your opinion, I might get a EP45T and see what it can do compare to my RE.

What ram do you have that work well with your board?

[pangingIII]

Thanks for your opinion, I might get a EP45T and see what it can do compare to my RE.

What ram do you have that work well with your board?

right now i use crucial value 2x2GB's DDR3-1333 CAS9-9-9 D9JNM 1.5v,
2x2GB OCZ Flex EX DDR3-2000,
and 2x1GB Crucial Ballistix DDR3-2000 2.0v. but the crucial value ones are best.
i also have a few friends who also uses EP45T's and they are now using Crucial value 2x1GB DDR3-1333 CAS9-9-9 D9JNM 1.5v (actually, they bought the one that are 3x1GB kits),
these Crucial value kits are overclocking well and are working best on the boards and are so cheap.



radaja, if you decide to try the EP45T's, also try the crucial value that i use... 2x2GB's DDR3-1333 CAS9-9-9 D9JNM 1.5v they are very cheap but works best.

pangingIII u forgot about me ... I just need some starting lines for 600 FSB testing ...

Couldn't get into Windows at 900/900/0/0 with all other voltages the same as I had been using. 900/900/0/50 booted right up and all seems fine, will run Prime tonight to be sure.
