Your drive settings are very high, raise skews to 150ps.

[waiho2k1]

Thanks for the input Dan, will try later to see

[gurusan]

just achieved this with this board

I'm having trouble getting past this clock though, would really like to do a 5GHz run but the board doesn't seem to want to do the FSB. I have tried up to 1.5V nb and it doesn't post at all :/ Pretty sure the CPU is capable of it but I dropped the multi anyway to see if I could get the target fsb first.

[radaja]

wow.gurusan,you got a great cpu there
very nice OC

[Hoss331]

Hi all, just get one EP45-UD3P and is having problem in getting my Q9650 stable @ 495 FSB (prime freezes after 1.5 hours).... settings as below, what's wrong? The ram is Gskill PC8500 PK 2GB X 2

Which test is it freezing on? Try this,

[RAMMAN]

this board is weird, settings i know are orthos stable if i overclock in windows simply wont boot. regardless of other settings 400 fsb = no boot, at 333fsb 3:4 and 2:3 = no boot, and recently i tried 5:8 at 333fsb too. it booted, but couldnt get into windows every time. so being stuck with a choice of 4:5, 5:6 or 1:1 divider plus my fsb limitation its impossible to get higher than ddr2-1066 :/ . i have tried changing performance level, timings and mch voltage.is that alone a good enough excuse to get a refund or replacement for this board?

[In-Fluence]

sounds iffy, what's your PSU like?

[RAMMAN]

let me rephrase that, settings i know are 100% stable if i raise fsb using setfsb in windows simply wont boot if i set them in bios.
unfortunately i dont think there is a way to change memory divider in windows, or cas latency in windows for that matter so im stuck with what i got.
psu is a thermaltake toughpower 750w. so far 435 fsb works with 5:6 divider using setfsb.

[Gaul]

max v mch for my GA-P45 UD3R is 1.62v on air, anyone ever touch 1.7v ? on air ??

[RAMMAN]

good news! i tried raising fsb with setfsb further, got to 460fsb orthos stable! funny how it wont even boot if i set 400 fsb in bios. still 1.2v mch, 2.2v ddr2, all other voltages normal. 5-6-5-15 timings. this is a higher fsb than i ever achieved with 2gb same voltages, i suspect setting performance level to 9 instead of 8 had something to do with it.

[User111]

know how to set the command rate to 1T?

You should raise vMCH, 1.2V is not really that much.

know how to set the command rate to 1T?

You can't set command rate to 1T on DDR2-Intel chipsets.

[User111]

why there is the option to set it? it was a mistake or what ....?

[Don_Dan]

why there is the option to set it? it was a mistake or what ....?

Well, command rate on Intel is a bit different from what is usually called command rate, that's why it's called 1N/2N. It works on the DDR3 boards, but it doesn't work on the DDR2 boards, though the option is integrated in both boards.

[User111]

perfect thanks

[RAMMAN]

i know but northbridge heatsink already gets hot as it is, how hot is too hot? im only going by feel btw as there is no temp sensor for it as far as i know.ud3lr has an inferior northbridge heatsink and no heatpipes compared to the ud3p/ud3r so im sure its going to limit me somewhat.

[M40TURBO]

Anyone know how much i should tighten the screws on the mosfet water blocks. It's the mips blocks for the ep45-ud3p. The one over the cpu starts to bend the mobo almost right away.. And i'm useing the original pads that are there.

[OC Nub]

I think Jor3lBR uses the mips block's for his UD3P, try sending him a PM.

Download a program called MCHTemp it will tell you the temp of the NB.

[the_real_7]

Been messin with this board after the bios upgrade which was great and solved my loop reboot and my x- fi fatality hiccups brought down to perf 8 and damn she snappie my everest score increased to 58.ms so next i tried to overclock to 4500 and i lowered back down to perf 9 and 5 5 5 18 crashhh , tested ram alone up to 1000mhz with a 8 x 500 she acted ok ...latency also went down to 56.2 ms but why can I raise cpu speed ? cooling is very good so is power supply im lost
I tried these settings but i get crash on intel burn

hoss i dld MCHtemp but 1,3 ALPHA7 , could you make it work on W7x64 ?

[Hoss331]

Yea it works, windows wants a digitally signed driver so the easiest way to get around it is press F8 just before windows starts to boot. It will give you a list of options, choose "disable driver signature enforcement", this is just a quick work around so it wont be permanent. My temps dont even register anymore, even with very high voltage, so I dont use it since it only starts to show readings above about 46C.

old air run

[the_real_7]

hey Hoss331 nice temps and voltages dude , 1.36 v and your running at 4.5 damnnnnn can you help me with my settings again ive been on this all day up and down and yes at 4.0 i have tight timmings and nice latency but with these p i pc 7200 i should be able to do a nice 1000 or more at 5 5 5 15 , just cant figure out why im crashing

I really want to try out the G.Skill ECO ddr3 sticks but they are so expensive. Anyone know other alternative modules that use the same low voltage ICs?

I have these waiting for me in the apartment office, I'll pick them up tomorrow and can tell you what IC's they have:

1.3v rated voltage.

Just to ad on the list for the DDR3 boards:
