Hi pangingIII

Nice memory sticks you have there.

If you remembered I had some problem with my EP45-UD3P, RMA it, they couldn´t fix it, got a new board, it´s working as it should, nice piece of machinery.

i've been running a few much more expensive ram kits on this board, both 2x1GB and 2x2GB,
they are running okay at DDR2000 but use too much vdimm and i don't like to running high vdimm all the time.
i thought i try somethin a little different, and got this crucial value kits, it came to my surprise that this D9JNM based DDR3 works quite good with the board. i still have a crucial ballistix 2x1GB PC3-16000 2.0v kit coming to me next week or so and i still doubting it that it will overclock well and with a low vdimm like i have with this crucial value ram.
anyway, i'm glad to know you got the new board and it works great now.

Anyone got 575FSB+ on E8500/E8400/E8600 settings for UD3P they wouldn't mind sharing?

Thanks

Anyone have some kind of instruction on how to set the cpu and mch reference values in bios? Everytime i change the value from auto to something else, the computer won't boot.

I did run a short test in december with my E8400@575, I got it 1M stable but more, here´s a screenie, hope it can help some.

It seem like 45nm (both dual and quad) like CPU ref at ~0,760 and dual seems to like ~0,700 for MCH ref and quad ~0,840 for MCH ref, this value is when CPU Term is at 1,20.

Have not test 65nm so much so I´m not sure what works for them.

Thanks Ghostleader that does help quite a bit

Thanks Ghostleader that does help quite a bit

Great

Right now I do run my Q9650 but soon I gonna swoop it for my E8400 and try to reach 600 so in the meantime you can fine tune the setup for 575+ and share with me and others.

I know I have been lost for weeks now. I missed my XS lol

Hello,

I am currently sitting at 4Ghz (finally)

BIOS F9
E8500 E0 stepping
GA-EP45-UD3P rev 1.0
G. Skill 8800 @ 1130MHz 1.9V

Below is my template. I think I can do better with the volts on the motherboard, but since I am finally stable I am a little hesitant to do random changes.

My temps are OK, looking at mid to upper 30's during idle and I get right around 65ish deg during prime95 small FFTs. I saw as high as 74deg during intel's burn in test.

Please help me optimize my O/C.

Thanks,
J

Does anyone has OC settings for an e5200? Looking to push one to 4.0ghz or more.

[radaja]

fatguy1992 posted some i think.check through the thread and see if you can find it.
im pretty sure he has/uses a E5200.

i have a gigabyte ep45-ud3p board with q9400 and gskill 8500 ram with the following settings
I managed to get it 490 stable in prime for 24hrs at the following settings
- mch core is a bit high, but i tried upping vcore and vtt and lowering mch core, but that didnt work





now, i want to try to get get 500mhz.
- any setting i do at 500, it freezes
- i've tried upping everything except mhc core
- i've also played around the skews but that makes everything unstable

any ideas for 500mhz?

Guys

Any improvements on BIOS F9 ? i have the UD3P rev 1.0 i see that is on GIGA's site the F9 final...

Cheers
Sergio

[pphx459]

Would like to know as well..

Try upping the mhc core, I had to use 1.46 for 500/turbo/pl8/2.40b

i own a ep45-ud3p rev 1.0 with bios f8 final, but its the hardest 775 board to get stable from my experience. I previously owned an abit ab9 quadgt and an asus p5k premium and my e8400 was stable @ 4ghz with 1.225 set in bios without any problems with ram @1068, pl6 . I have 2 x 2gb ocz hpc reaper pc8500 and i am having a hell time gettin this board to run @ 4ghz with decent memory timings and voltages . My only stable config was the default settings. I am now testing @ 4ghz with 8.5 x475 fsb, ram settings standard, xmp disabled, 400 strap, ratio 2.00d, ram settings manual @ 5-5-5-15 2.14v, pl9, llc enabled, cpu @ 1.2500, vtt 1.24, vmch 1.28v, every ref up 1 notch, case closed, room temp 23C, eist and c1e enabled cause i don't like to run a 4ghz cpu while browsing websites.

I guess those settings dont work in bios f9 anymore, and i hoped it will be better than f8, i guess i was wrong, i am now @ 1.34v vmch in bios and still not stable . Dont know what to do anymore cause orthos is failing with round error after 6 minutes or even quicker.
That's the stupidest thingh ever, the bios update not only erased my overclocking profiles, but also made my computer totally unstable@ the settings it was 24/7 rock solid before

[lilneel12]

ive tried that voltage already with no luck, within a few minutes at load, it freezes.
-any other ideas, i really think the chip has a lot more in it, but the board is stopping me, bc i got it to post at 525mzh fsb =4.25ghz, but it freezes while loading into vista- would that be a ram, motherboard or chip issue?

Try upping the mhc core, I had to use 1.46 for 500/turbo/pl8/2.40b

Hi, guys!
This my result with Q9650:
MB EP45-UD3P (BIOS F8f)
RAM 2x1GB Crucial
PSU Antec TPQ-850

and linpack:

[bluestang]

Right now I'm at 8x525 @ 1.40v in BIOS (LLC enabled). Would 8.5x500 be easier and less volts for vCore, VTT and MCH ??? Cuz I'm thinking of getting some KHX9200D2K2/2G (2x1GB, 1150 MHZ) and running 8.5x500 with mem at 1200 MHz. My ram in my sig just can't do that and I don't need 4gb on XP right now. Any ideas or suggestions? Thanks!

Andressergio, I am on the f9 bios. Is working pretty good for me.

Indeed, nice. Welcome and where did you get that mchtemp monitor? cool.
