** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

[Oztopher]

Actually the latest bios is f6 for the UD3R

I was talking about EP45T-UD3R, the DDR3 version of the board

[clo007]

aaah gotcha.

LLC - load line calibration

whats the deal? safe or unsafe? is it just a matter of personal opinion, or are there people who have actually fried their chip from voltage spikes under load? if i understand correctly, llc compensates for vdroop, basically by spiking voltage.... ?

thoughts?

[fatguy1992]

I have LLC enabled and personally I like it, it makes it way easier to stabilize the OC (well for me it does).

[Mean Machine]

I'm through with this board now.


Even one MHz FSB higher and it shuts down...

Nice work

Is that stable?

Could u please post ur settings?

[radaja]

very nice mean machine.but has it occured to you that the cpu wont go any higher(hit its limit).i bet if you set the multiplier to 8.5 or 9 you could get a little higher fsb.hell even 8 and you could probally go alot higher.any ways great job with that clock

I have the same limit with three separate CPU's regardless of multipliers. I'll see if I can give you my settings later on, but I promise you, they aren't pretty. It was 1.52V MCH and 0.93 in MCH ref or so.

550MHz FSB isn't particularly stable (once again, regardless of CPU frequency, multiplier, MCH voltage, straps, you name it I tried it), but it works for Pi 1M if you're lucky. If you need stability, about 525 is where I need to be. It just doesn't work well enough for me, the board keeps ing all the time, I've spent tens of hours getting it stable, but over 525 it's just not that.

What's so fab on 552FSB and a CPU-Z screenie ? His CPU speed is mad for air or water ( but with extreme cooling is average ) Would love to see a 32MB run... as taking a CPU-Z, 1Mb run screenie takes one minute of stability in windows... don't get too easily arroused guys lol

[Mean Machine]

My thoughts exactly. That's why I wrote "I'm through with this board", since it doesn't do anything better than the 552MHz FSB no matter how I try.

[Rattle]

try a diff cpu dude, only take me 1.3625 cpu volts, 1.26 vtt, 1.3 NB with refs at .768 and .758 to do 550 prime blend and 3d stable....

[Mean Machine]

Already tried an E7200 which behaved exactly the same on the board, regardless of voltages.

[BuGjAE]

@ Rattle ,What's your board Revision? 1.0 or 1.1 550x8 is the greastest clock that my Cpu can do but seem no possible with this board ??
Any way could you post yr full BIOS setting ?

[radaja]

well i was able to get it somewhat stable a while back at 556fsb.so it can be done

Nice OC, left only the ET6 settings or BIOS settings, could you post it?

[BuGjAE]

Very Nice radaja, ask some Question I notice that my 12+ Volt Rail is alway below 12.00 It's around 11.87-11.92 in ET6 And never go above 12.00
. Is this something wrong with my mobo? I see you have alway over 12.00 that u show ur post in the past.

Note: I use Enermax 460 Watt for my system and everything run up as usual.

[radaja]

BuGjAE,from what i understand its better to have a single rail psu.with my antec 550W psu it was multiple rails and my 12v would always go from 12.30 to 11.30 under load,it seem to stay in the 12.49 to11.98 while doing large fft's but when it got to the small fft's it would drop to 11.98 to 11.39 area.but now that ive change my psu to the PC-Power&cooling 500W with a single 12v rail,even using my quad i have yet to see my 12v line drop below 12.11,its usually at 12.51 to 12.49 under load.and it seems that having a very stable single 12v rail with high amperage allows me to run my quad with much lower vcore.i assume it because there are less flucuations in the vcore that is being supplied.

Hello...

...is some new bios out there for the EP45T-UD3P DDR3 Board???

I have now F4

...thx

[Leeghoofd]

F5 mate : EP45T UD3P F5 Bios

[radaja]

these are the bios settings i used for the 556 and 560fsb runs,everything that is blank was left on auto.and the 560 run the mems are running 1:1 using 2.00D and pl10 W/lower vdimm.

Thx ...and whats new in this?

[bobreece]

is it ok to not reinstall windows if i am just swapping one mobo for another but both identical as i have revieced my rma board??

[Loony]

How does this board work with using all four dimm slots? I wanted to use a 4x2gb set for 8 gigs of RAM.

[clo007]

You should be fine. I went from a rev 1.0 to 1.1 with no issue. well, except this stupid memory slot bull!

[radaja]

loony,ive used 8 gigs of G.skill pc8800's 4x2gig running 1:1 overclocked at 8.5x518 and using quad 9650 and it works great.with my E8500 i was able to run 1:1 with 8x545 pretty stable.
