@ hoss

I wish i had an ud3p now that high fsb and speed with a Q9550 stable... the highest i reached so far is 1.21v @ 490 FSB cant get it higher or it wil become unstable..

[Hoss331]

Theres still a few ud3s floating around out there, get one.

[MrDucky]

i know just dont have the money and i dont want to pay like 50 euros for just 2 or 300 mhz..

me too.... I can only do 490x8.5 @4165 1.28 vcore but temp is
high enough I think I 'll stop Oc at this clock. Anything over 500 fsb is not possible to stabil. Even 495 my chip can't do also.

I can boot and stress but nomather what i do i get an error in prime.. not small fft but blend

Well, if it's for socket 775 I would say it does.

Ok.. this is either a nice troll vector or awezum humor. I refuse to believe that one of us is ignorant.

Now back to the point: Has anyone tried the Thermalright HR-02 in a USB3P? Does it fit well, in all orientations, without crashing into anything nearby... chipset sinks, memory..etc ?

it fits the ud3p so i would think yes

Yeah, I also did a search and found that odd peculiar post...

Thermalright HR-02 S/U also fit the mosfet but no need for that because the gigabyte heatpipe can be pull off the nb block or the mosfet block.

Why is this post odd or peculiar?

Simple. It's from 11-21-2008. Dude probably meant the HR-01, and typo'ed HR-02 (??) ... The "real" Thermalright HR-02 that I am aware of is (C) 2010, as noted elsewhere and here -> http://www.madshrimps.be/vbulletin/f...spotted-72748/ "9th June 2010 .. During Computex the company showed several new creations and among these we found Thermalright HR-02"

Does ga-ep45-ud3p have some kind of mosfet load protection or something like that. I actively cool them and they are not even warm but I'm having hard time to make 20 LinX passes with q9650@4500MHz(9x500) because my processor needs over 1.4V and when I start running LinX, in a few minutes the system shuts down (fans not spinning) and restarts. If I raise vcore the system shuts down and restarts in few seconds so the more vcore I set the less LinX passes I get. Cpu core temperatures reach about 85C and Cpu Thermal Monitor is disabled.

EDIT:
It turns out that the cpu needs lower temperatures. It was strange for me because with my previous board heat issues just made LinX to issue wrong residual and this board has its own way of saying: "Hey you need to chill this CPU" .

[MrDucky]

hi what is the best revision cause i may get an ud3p rev 1.0 for like 40 euros...

[radaja]

1.0 i found to the best.
1.1's have quirks with certain straps and ratio's
havent tried a 1.6 though

[MrDucky]

ok then il buy it and sell my P45 T2RS+ may get the same amount as i buy the UD3P For haha :P

[BuGjAE]

I need 1.46 vNB to get 500 fsb run prime but I don't hv much time to test long run ,So 1.46 vNB is it save for 24/7 usable I use stock cooler UD3R board.?
Thanks for advice.

[Hoss331]

1.1's have quirks with certain straps and ratio's

This can be said about some of the 1.0s also, mine in particular has problems with high mch voltage when using 2.40B.

You should be ok with 1.46, if you can get a fan on the nb that would be good but its not required.

yea this is true,i have had different quirks with all my ud3p's like mch voltage using the 2.40B with one 1.0 and 2 1.1 boards.on 2 of my 1.1 boards i had the cant boot using 2.40B with strap set to 333,but on auto it boots.
last month i went throug five 1.0 boards and four 1.1 boards and 2 ud3r 1.0's and 1 1.1 ud3r's and i have to say they are each there own boards.i tested them down to two good ones and sold the rest.but still the 1.0 were the most solid ones.
yesterday i sold one of the good ones and should have my last one sold soon.
they are fun fun fun

[Gaul]

pfff some creepy high temps for just poor low volts hoss

AGREE with this statement

my q9550 4 GH need 1.216 volt, but max temp only 60 C

[Revv23]

anyone have a total NB failure on this board?

Today I'm browsing the internet after about 200 days without shutting down i BSOD. Then complete boot failure; pull out a stick of ram. Good to go. Put in another, down again. So I figure I lost 1 channel. Not so lucky. Using one stick I get halfway into windows boot and lock up. At this point i can't even get into bios.

Who still makes a good 775 board? I can't afford a new rig today and looks like the UD3R has been discontinued.

200 days... I've had this happen (maybe?) on three separate instances where I've run hardware almost non-stop for years, and then offlined said hardware for 1-3 days. Boards affected - two MSI-9105s, one ABIT VH6T (this one ran great for 3 years straight with very little downtime, until I turned it off for 1 day.), and maybe one SOYO-6YBB (not sure on this one). All these boards were made, IIRC, during the taiwanese-capacitor-disease era. I blamed dried/crappy caps in those cases, but who knows !? I was hoping such nonsense would vanish in this mostly-solid cap era. But who knows..!? I had a solid cap blow-out already in 2010.

Woo hoo.. my first USB3 flash drive test + USB3P.





F2D beta firmware in control, as original firmware was... USELESS!
Also, hdtune might not be the most appropriate software for this. Suggestions welcome.

Did a little SPI benching on the 9550 tonight, no dice runs yet just ambient temp water.

[mreld3r]

Dang hoss, thats a nice one you got there

[pmacdonald]

I've been trying to get a fine tuned 4.0GHz but have run into a few problems. I'll start off by listing my setup:

Intel Core 2 Duo E8500 Wolfdale 3.16GHz
Gigabyte GA-EP45-UD3P LGA 775
EVGA GeForce GTX 280 1GB
G.Skill PI Black 4GB (2x2GB) 240-Pin DDR2 800
Xigmatek HDT-S1283 120mm HSF w/Retention Bracket
Corsair CMPSU-750TX 750W

RAM Info:
Default Timings: 4-4-4-12 @ 1.9V or 5-5-5-15 @ 1.8V
DDR2 800

Note: VTT = CPU Termination

I began my OC by starting with my RAM. I was able to successfully achieve 500MHz (1000MHz) with 5-5-5-15 timings and at 1.98V.

From there I began to adjust the other settings in the bios in order to hit 4.0GHz. Here are the settings I ended up having trouble with below:

VTT Problems Begin
When I attempted to change the VTT nothing worked. The system wouldn't boot with VTT values between 1.2-1.3V. I ran EasyTune6 to see what the VTT was running at and it turned out to be 1.6V! 1.2-1.3V are the recommended settings and from what I read you shouldn't go higher than that. This problem stems from my RAM so I set all of my BIOS settings back to default in an attempt to find a solution to the problem. Here is the updated BIOS below:

Attempting to find a solution
I immediately attempted to OC my RAM to 533MHz with the VTT limited to 1.30. I started with the DRAM at 2V and the system wouldn't boot. I upped the voltage to 2.1V and the system booted to the windows welcome screen but then it would just reset itself. This happened at 2.2V as well as 2.6V.

Basically, it seems in order to enable my RAM to run at 500FSB my RAM voltage has to be turned up extremely high. I didn't feel it was safe to attempt any more than 2.26V since 1.8-1.9V are the stock values. I wasn't able to achieve a 533MHz OC.

Other Notes
I do not have the funds to purchase a new set of RAM.
I tried similar settings with all of the above numbers with the 333 latch.


Questions
How do I lower the VTT but still have the RAM run at 500FSB?
Is it safe to run the VTT at 1.6V?
Do you guys/gals have any recommendation on getting a successful boot with 533MHz?

[radaja]

pmacdonald,here i made some changes for you to try at 8x500
this should work for 533 fsb with your ram at 1066 too.just a matter of
