thanks for the reply Jor3lBR,

than i have another question for you,

i have my q9550 e0 running on 485 fsb and 4125 Mhz, this is on a ga-ep45-ds3r. quite good actualy. what do you crank out of your ga-ep45-ud3p? think my processor will run better on the ud3p?
or do you think i can get more out of this board? i turned of all stepping stuff, upped my Vcore to 1.44 Mch to 1.5. that's it..

edit: changed my bios to:
CPU Clock Drive...........................:[900mV]
PCI Express Clock Drive...................:[900mV]
CPU Clock Skew (ps).......................:[0ps]
MCH Clock Skew (ps).......................:[50ps]

fsb 500 it is!
thanks

or is there a little better tweaking in the UD3P borad?

EDIT:
also i see it has 6 reg sata plugins and 2 esata. can you use reg sata cables on the esata?

i've got exactly the same board running a q9550 e0 @ 500 fsb and 4250 Mhz..

finally someone with my board..lol
what kind of mem you running on it?1066?
oh please do share with me some of your settings ive been tinkering with this board trying to get more out of it and i never would have thought of getting 4.25ghz out of it plus only have nddr2 800 mem has me stuck where im at now.

keep in mind this is my first build but have had alot of fun messing with it. im not to sure on some of the settnigs and what they do. so if ya dont mind sharing i would be greatfully apprecative of any info.

anyone running 8GB on this board?

how much MCH did you need to pump to keep a FSB over 450+

My current 480 FSB profile is 1.34v

nice.

This board is the KING of 4 DIMM OCing :up:

Anybody else using 8gb ram? I am having a hell of a time getting my 9650 past 3.8 stable on air. I am using 1.42v (!!!) and I have messed with a lot of timings...I am using 2x fan lapped true lapped chip 900 with 2 extra fans, 6 disk raid 0 and 850w psu. Anyone have an ide? My idle temps at 3800 are ~35/40, load temps 57/62, ram running at 1140, but I can't get the chip past 475 fsb...

Assuming you have dropped the multi to see if the RAM/NB are holding you back and not the CPU? Running 8GB at 1140 is already a solid OC for 4 DIMMS so you might have to drop down a divider to get that FSB up.

So you think it's the RAM holding me back? I'm at 8x475 and I'd really like to hit 4ghz...you think I need to go up to 8.5 or 9 and drop a bigger divider in order to do so?

It is probably the board/RAM combo holding you back. I don't have 8GB of DDR2 that will go that high but stability at 1000Mhz is easy on this board with 8GB, post your settings here and what RAM is it exactly?

I'm using gskill 8GBPI...I have Q9650 at 1.374v and the ram is at 1.9v. I am just usnig 8x475. I would like to drop down to 7x with a high FSB and a divider but even when I switch ratios the fsb will just not stabilize even up to 1.43 volts. I have tried messing with mch, pll, all kinds of settings, nothing seems to work...

Anyone using the GA-EP45T-UD3R/P should get this kit if you're having trouble with your current kit ! (this might've been said already...)
http://www.crucial.com/uk/store/part...KIT25664BA1339

They use D9JMN IC's and overclock really well with my board. Got them stable at 1800 CAS8 with 1.8v. Still yet to try for more... going to wait until i get some heatsinks for them.

Thx Oztopher : kit's that absolutely do not work are my Diablo Micron GTR rams, no way to go over 1600mhz stable... with the EP45T UD3LR...

Yeah it seems the D9GTR's don't work well at all, and need alot more voltage to keep them stable (not sure what other sticks don't work well, but im guessing D9GTS?).

But seriously, this kit im using now is excellent, can't believe they were only £56 :D I also booted 1900MHz CAS 8 with 1.9v, it would probably be stable as i was able to boot into windows with a minimum of 1.8v. Couldn't even boot 2000MHz, as im finding it hard to get 500FSB on my Q6600 ! *eyes up a Q9650*

EDIT:
Oh, and i found the straps acted weird. At 400x9, with the 333 strap, i needed 1.9v to even boot 1600MHz on the RAM. But if i used the 266 strap i could get it to post with 1.5v ! It just needed abit of MCH voltage as it's quite a 'tight' strap. But at 450FSB+, the 333 strap works like a charm, thats the one im using now for 1800MHz w/ 1.8v. It was the same for most of the BIOS versions i tried.

This kit only really likes CAS 8. I could only get 1600MHz and lower stable with CAS 7.

@Lee, I could really use one of your BIOS templates for that E7400 chip of yours at 500 FSB. I'm having a hard time with Prime95 stable after 3-4 hours. System crashes either at 320k or 640k in Blend, and at 48k or 64k in Small. I think it's my Ref's that are giving me trouble. Not sure if the E7x00 Duals require the same treatment as the E8x00 Duals do, especially on a DDR3 board.

For some reason I can't get the item I select in the boot menu to boot. I mean the menu you get when you hit esc or whatever it is during the POST. I will select my USB drive, hit enter and it just boots from whatever is selected as the first boot device in the BIOS. Any ideas?

Have you changed "Harddisk boot priority" as well as "First Boot Device" to the drive you want to boot from?

It boots from whatever I tell it to in the BIOS. That's not the issue. The problem is that if I want to install from a USB drive or boot it into DOS I can't do so by changing the boot menu via hitting f12 which is available during the post. Whatever I select there isn't respected and the drive which is selected in the BIOS ends up being used.

I'm usin 8gb Pi 9600's and cant get them stable at 1100+. 1:1 for 8gb i think is all we can do at high FSB. I've tried everything, even a new board. No go with dividers and 8gb for me. 4gb i'm good at 1250+. To me not using a page file and 8gb 1:1 feels better than 4gb @1200+. I have real good cooling on NB and RAM.. I've just learned to live with the 1:1. I know i know just something about 8gb at 1200 is sexy...oh well. Anybody else using 8gb successfully at high fsb? Pleease chime in....

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.

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 :down:

I was trying 8gb of the pi's also at 1200 but was a nogo, need to put them back in and tweak some more, been lazy lately with ocing.

does anyone have a link to bios templates

and maybe something explaining MCH Ref , CPU ref values.

this board is quite nice, havent had much time to play with it, but had the FSB up to 475, but had a reboot loop several times. I pulled the battery, and ended up getting distracted with some other stuff i need to do. Will get more time tomorrow night to toy around. I did read some people had problems with FB bios. I think i have Fb or F8..i forget now. The board is rev 1.6 though, bios is dated May 2009.

this thread is huge..it will take me a month to dig through it all:ROTF:

OH its the UD3P btw
