one other thing i had the ddr3 version and it does not do this noise also it does not change voltage when llc is enabled where as the ddr2 board i have now does by one notch or 0.00625v???

anyone guys opinons and advice

apparently this is a common problem(high pitched noise)with these boards.i think it has something to do with the PWM when under heavy load.i dont know if there is a solution for this.i have seen a few guys RMA thier board for a new one.

cheers m8
i had the ddr3 version 2 of them and it never happened seems like the ddr3 version is a better board but very buggy o.cer

what ram are you running your EP45t-UD3P with m8 as i had the board and tried to run my cosair 1800mhz 888 24 and it would not have it it hated everthing with the ram except 1333

Tried to warn you Bob about the ep45t:shrug:. I was running the crucial 2000 cas 9 2gig kit on it, got it to 2000 but very unstable, but ran fine at 1800. Gigabyte has it listed as compatable on the board, and will run 2100mgz, that just isnt true, it was very very hard to get it to run 2000, and lots of lockups.

the board has gne back i now have the ddr2 version not hppy with it though as the LLC does not get rid of vdroop fully and there is a loud high pitched noise from the board think its another rma again

If you dont want ud3p grab the ud3r, the ud3l cooling is not as good as ud3p or ud3r

@ bobreece - having a small amount of droop is better than no droop or even worse having vcore increase under load. Due to the low amount of vcore output filtering caps on a mobo, they simply cannot filter out the spikes during load to idle and idle to load transitions. Also the amount of ringback, overshoot and settling time is increased significantly when LLC is enabled. You wont see the spikes with software or DMM the transients are too fast, but they are there. Having a small amount of droop in the design is better than no droop at all, as these issues are somewhat reduced.

Being a 6 phase PWM its pushed pretty hard when overclocking, so if you're worried, return it. Maybe this happens with all boards but I have only seen a couple of people complain about it.

did anyone try using dual LAN connection as 1 connection, pretty sure i read you can plug 2 Ethernet cables and use it as 1 connection.

I had 4 UD3P ver. 1.0 and 1.1 + one Extreme and never observed what your describing.

May not mean anything but I would ask for replacement.

cheers guys will rma it

Has anyone figured out why memory doesn't work well on this board? My Crucial Ballistix PC8500 2x1 won't run in dual channel. I have to put it in a red and yellow slot but it won't run if it is in the same color slots. I'll try three sets of Corsair XMS2 2x1 PC6400 tonight.

did you try changing volts to 2.2 (i think is your ram volts) and then switching them to see if they run dual channel?

Can someone look at these and give me some advice or pointers please

It will boot up, green windows load screen, then go to the windows circle things and then crashes giving a memory dump.
It will boot into windows fine with standard settings.
Strange thing is these ran fine at the weekend :(

so cant oc mu E7300 over 400fsb stable.
tryed 400x8 and x9 and x10 all same.
one time idle 430fsb was ok but not stressable.

what is wrong
http://www.wolk.pri.ee/kb/muu/ptiu.png

more vcore maybe :rolleyes:

ur NB vdimm is more than enough for 400ish fsb, also i think u dont even have to touch MCHref, ICH/IO and ICHcore try more vcore coz i had similar error at 1024fft when i thought it was my RAM or NB but once i raise my vcore a notch it passed

flo

Mask, your MCH Reference is too high. You will want change your CPU termination voltage to 1.2V then set your MCH reference to .70 or .72 then switch your CPU termination back to 1.22 (if you want to keep the CPU Term there). These boards are extremely picky with MCH reference.

Gigabyte boards (at least P35) and Ballistix don't like each other.

Was it 400x10 stable?

Phunky Phish:
Your ICH core is too low. It should be 1.100v. Try more vcore too.

2.2V on my 2.0V Ballistix to make them run under speed?

hmm i thought it was these

http://www.newegg.com/Product/Produc...82E16820148069

but i agree with what touche said i use to have ds3,p35 and crucial didn't like each other at all so i got rid of both crucial and board and went gskill abit and now im back to gigabyte, so im guessing its same problem still

It could be those memories. I was just going off of what is on the Crucial site now. I had D9's but when I RMA'd them I got the newer ones.

Tried my ICH core @ 1.2v and Vcore @ 1.26250v but she still wont play ball again!

I am gutted as it ran all day Sunday with no problems!

To late now but will try the lower settings I already posted but 450fsb. See if that will load and is stable. :confused:

This is kind of what happened with my E6600. I got that booting into windows up to 440fsb but then it crashed and after that nothing I could do would get it stable again. :mad:

Disable LLC, set vcore 1.41250, leave ICH core 1.100v. Set memory PL 11 or higher.


asap:
How come you changed these?

What difference do they make?

I can't believe how well and solid this board is. With Crucial B-Stix 8500's and KHX 8500. Both ran very good on my older P5K-e but required about 2.3 or so to do the same. I think that speaks to the quality and design of these later products. That goes for proc. as well. Crap, with DI even not too long ago clocks like these were only "possible" let alone the norm. I included bios info. I too had an issue with Prime ending. I upped vcore a notch, same time out. Obviously that was not it. Lowered it back and bumped vdimm up a notch. Same thing. Then I remembered reading someone's post about lowering MCH. Tried that and it has ran as long as I can stay up. (2:00am - got to get up @ 5:30) Lowered MCH ref. as well. Maybe it will help others as well. I'll say it, as some may be thinking it. This takes some time and experimentation. Enjoy.

I can't get past 544 no matter what I do. My board also seems a lot different from all of yours, it requires quite high reference voltages and... Well, yeah, high voltages on everything. F8a seemed to improve things for me a lot, I'm just only getting used to the board, but with F6/F7 I was struggling to reach 500 stable with roughly the same settings. Also, F8a sometimes resets itself after a failed OC attempt, which the earlier ones didn't do for me... A definite life-saver, I was pretty close to dropping my Vapo LS on the board when I had to reset it myself for about fifteen times in a row...

Seems to be some interesting issues with D9 chips this time around as well (remembering the 965P-series), my Cellshocks aren't as well-clocking as on my Maximus II Formula.
