[Team.AU] Gigabyte GA-EP45T Extreme - P45 DDR3 Monster

[chispy]

Looking very promising this board too ,Tim what PL were you using to boot in Bios when you ran the cpu on LN2 ? If you remember.
Keep pushing it bro , Poor E8400 , CPU-Z screenshot shows 2.0v

[Nosfer@tu]

First round with a bit of LN2 @ -100C
Efficiency was not an aim, hence the RAM timings.
But i know for sure it ran the same MHz at 6-5-5-14 1T but i ran out of LN2 for higher multi.
Pumped more vCPU than i needed, and manually set VTT and PLL to 1.72V (measured) and 1.92V (measured) respectively.
Vdroop is a big problem when running 32M, but 1M hardly anything.
NB cooled by P35 heatsink on air.

Wanted to test what a real benching system might handle, hence two sticks of RAM and two cores.

EVIL

Great work T_M.

I 2 have Coldbug at -110

Migth just be the caps, anybody have a clew what to change them with ?
-110 SUX WANT TO GO LOWER

EDIT: Btw if any readings with oscilloscope is needed please say so.
I have access to every measuring tool in the world here at work!

[T_M]

PL was Auto all the time, and in Windows after booting at 620 it was reading in Memset as "4"

[TheKarmakazi]

Great work Tim, get an 8500 in that board next! 650FSB on 8500 get some really nice spi!!

[chispy]

Thanks for the response bro , Auto PL in Bios worked for you.
Keep Pushing it Tim , great job.

[Nosfer@tu]

Thx for sharing.

Will give the board a spind again in the weekend

I m testing EP45-Extreme but DDR2 version.

And after few boot , i saw that that board needs alot of VTT to boot to 600mhz !

Edit :

yes it loves VTT

Edit :

CPU in air and NB also

Memset locked ???

[artkobe]

How about this M/B Ram-OC?
Can it 2000+Cas7 stable

[T_M]

No, DDR3 RAM clocking on P45 is still a serious problem

yeah it's locked for me too

how much VTT did you use EEEEEEK

[NinjaZX6R]

I am all over this board!

Wonder if this place actually has it: http://www.alwayslowest.com/AL/index...s&part=2869838

Anyone have any clue when this is going to be out?

Worse than P35? Hit DDR3-2000 at 7-7-7-20 on my Blitz Extreme. Think this board will be better?

-Collin-

[T_M]

If and or when the kinks are sorted out it should be capable of those standard sorts of OC's.
But for now I cant even get more than 800MHz very stable, and theres serious divider issues.

i am pretty sure that p45 ddr3 will rock. but when? nowadays 1333 is faster than any higher freqs. weird. i don't think its mfc's bios related rather intel related.

[T_M]

BIOS version f3b is the first to make this board DDR3 capable

First RAM testing:
900MHz 7-6-5-15, 2.1Vdimm

ing sweeeeeeeeeeeeeeeeeeeeeeet

[T_M]

Just doing some quad FSB testing and 460 was stable with no tweaking.
Pushing for 470 now.

[Benny Lodewijk]

Tim, how about 2T/1T issue ? It seems no changing in F3B BIOS.... but this BIOS change a lot in memory performance i think

[T_M]

Yep still no change between 1T/2T, even if you set it in BIOS.
Memory performance of 4.00B is good, but at the same settings with 3.20B or even 2.44B it fails to post.

Bumped up vMCH manually to 1.35V (read), locked the VTT and PLL at the same settings as Auto 450fsb (1.52 and 1.795 read) and managed this:

[Gouhan]

Wow amazing stuff
I'm loving this board after endless problems with the EP45-Extreme, switching to this one and reading here on XS gave me hope.
Can boot windows at 620 fine, looking to push to FSB's like you have. (Still on F3a)
Excellent clocks T_M, this is mt P45 board of choice

[strange|ife]

why does memset lock me out of being able to adjust anything?

[Harshal]

Great info in the thread mate!!
I will give my E8400 and EP45T-Extreme LN2 action soon
Thanks for the BIOS too

@ Thomas, what VTT were you pushing on EP45-Extreme?? My Xtreme board can do 570FSB boot with 1.36V and ET6 makes 590 possible nothing higher. Same chip does 590 in Ep45-DS3R and 610 with ET6/set-FSB :s

[T_M]

@ strange|ife - no idea man, no problems for me using the latest beta available on XS

[T_M]

Reset a few BIOS settings and got the board to successfully run 2.40B so played with some more FSB on quad.
Without much trouble got it doing CPU-Z to 515MHz on 4 cores, and 2M at 495MHz

[youngpro]

board looks okay to me
using c8 but just seeing what it can do of course, not bad ram speed being reached on a kit of mine that isnt the strongest ever, but 1050 on the trams with 630 fsb and low pll and vtt used is alright with me
