Gigabyte EP45-UD3P - out of the box and almost auto setting -> boot @ 620FSB easy.

Well if you can see a reference voltage next to anything manually set it to that so then if you up your FSB they should remain locked if you want to be on the safe side.

What the hell mobo & CPU blown up?....could understand the mobo burning out, but the CPU getting killed as well???...MOSFET even melted the soilder contacts, must have got REALLY hot.

[OCX600RR]

I hear this high pitched noise as well on mine whenever udner heavy load...balls!

[nugzo]

I was opening a new tab to newegg after reading first half of thread. I've since closed it without ordering. i'll wait for a few. Sorry for your loss guys. Who had the 3rd e8600 die? PcCI2 (1) , dinos (2) and ?. My EVGA 680i's all had that high pitched noise while stressing. Annoying!!

Alright thanks Im glad I asked. My CPU PLL was at 1.8v, its probably been like that all day and thats something I would have overlooked for a long time had it not been for easytune. Now its at 1.35 and MCH is at 1.4

I havent heard any high pitch sounds yet. I primed for probably about 4 hours total today and everything is quiet, thank god. Sorry about your boards, I hope mine doesnt follow.

yep mobo and cpu

the good thing is about RMA ,next Friday a new EP45-UD3P from Gigabyte will be here

i think is Thomas ,but not the 3rd ,he is the first

[PcCI2iminal]

Have u tried EasyTune6? Damn Im loving that app for volts and clocks on the fly, can crash SuperPI and then tweak again without a BIOS revisit. It beats SetFSB imho.

sometimes but i prefer to set all the voltages on bios

are you going to the beta bios?

i'd love to get a E8600, hmmmm

F4-4(pi bios from Hicookie)




4500MHz (Intel stock cooler room temp @ 23c)





i will try 5Ghz with some extreme air and then i will give some cold

[vera]

how is vdroop?

[Alcibiades]

Hey what voltages should I be watching out for? Ive got everything set on auto except for Vcore and memory voltage. I really dont want to fry my stuff.

If it's the same as the EP45 and EP45T Extreme boards,

manually changing the
DRAM Voltage will scale the following values if left to auto
MCH/DRAM Reference
DRAM Termination
Channel A Reference
Channel B Reference
I manually set all these to ~ 1/2 DRAM Voltage for high frequencies

and manually changing the
CPU Termination (aka vTT) will scale the following values if left to auto
CPU Reference
MCH Reference*

Again if it's like the EP45 Extreme boards, some values entered in the bios will not be what is reported in ET6.
Looky here

for a 45nm cpu, watch theses voltages
CPU Vcore ..........max ~ 1.45V (depending on ambient room temp!!!)
CPU Termination .....max ~ 1.40-1.50V
CPU PLL .............max ~ 1.60-1.70V
the above max suggestions are only a guide, some have been running higher vTT and PLL for months with no problems... so far

* I found scaling back the MCH Reference volts after increasing vTT seems to have helped me find stability when overclocking.

[BoldEagle]

Excellent answer and very informative .

[PcCI2iminal]

how is vdroop?

with the load-line enable the droop is zero - minimum

Alcibiades nice effort there,i will check the voltages on bios and compare with ET6

[PcCI2iminal]

SanAce 9SG1212G101 (F12-HHH) 120x120x38mm 6000rpm @ 260CFM + Gigabyte G-Power II Pro







room temp 24c
max clock at 4900MHz
fsb @ 650MHz
and pi @ 4750MHz
hmmm 650,fsb not bad at all but i dont like the max clock


my dead e8600 (Q820A599) was better (TRUE + SanAce 102CFM room temp - 25c)

like to see the 1m pi on that 4.9, if u did a 9.1s w/4.5

nice to see someone else pumpin 1.5v can quad handle more less voltage then a duo,
or is it samesame

i never had an air quad @ 5GHz and all my quad needs more vcore than any 45nm duo
well, air 4GHz+ -> core2 duo territory ,they need less vcore than quad but some have been running q9XXX @ 4GHz with only 1.3v or less

[PcCI2iminal]

more vcore and LN2 soon ^^

I have my work system running 4g with a Q9650 @ 1.28v

that is great for work, love it,

but this quad, i want to push, so the gig and Vcore have been pushed...
I want to go as fast as possible on air, then i am gonna try water.

[bingo13]

same here man
my gem E8600 is dead

Now wait a minute, I thought it was impossible to kill a 45nm chip even though I have seven 45nm paper weights on my desk...

I blew this board out in two days, figure that extra ounce of copper must have kept it too cool....

very nice man

i can ran a qx9770 at 4ghz with the same vcore but its not fully stable



but i have a great Q9550 E0
3870MHz @ 1.22v and 4GHz @ 1.288v (only for benching)



4GHz @ 1,22v

yeah with 1.5VTT like you guys have been claiming.... admit it you got it wrong

[GAR]

Whats the difference between F4 and F4-4, or even F5A??? im using F5A, any advice, thanks.

[Viss]

F4-4 is made to be fast in superpi 1m (probabaly only 1M, slower for all other tests). I think it lacks the E0 support to be fast in 1M (same with Maximus bios for exmple when penryn came out).

Looking forward to your LN2 results CI2iminal mate

nice
shame your CPU is a lot worse than your previous one

[PcCI2iminal]

nice

thx mate

shame your CPU is a lot worse than your previous one

the previous reached 6Ghz+ with only 1.75v (pi or screen)and now 1.75v is a no go

[dinos22]

thx mate

yeah i can imagine
that last CPU was similar to mine heh

but knowing you i'm sure you will stumble on something soon hehehe
