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

[mop231]

p45 for oc'ers look awesome but those volts

[T_M]

i have a feeling it won't be as bad as it's been made out to be

anyone use the Gigabyte DDR2 cheaper x48 boards curious how they perform as well?

[T_M]

That doesnt really belong in this thread dude.

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.

good start mate

[ZoLKoRn]

cool so VTT 1.72V and PLL 1.92V wow looking very high

[Oliver]

Wise words from Sam...

vpll > 1.70V will make it degrade then die
vtt >1.45V is 100% guaranteed death for quad 45nm

[natedog420]

nice board and clocks to. did 2.4v of pll to a e6300 on dice and it didnt like it lol. it was fun while it lasted

[Harshal]

Good Start mate

Awaiting my board!!

[Extera]

Nice board, but crazy voltages there....

i'm awaiting your high VTT endurance test results

[[XC] gomeler]

Can you log how many hours at what voltages just in case the chip does succumb? I'm hesitant in sticking my QX9650 into the P45T-Extreme sitting here before I do my 4850 + X48T benching

[Benny Lodewijk]

good start T_M !!!.....the voltages are nuts !

lol you shouldn't say this Oliver

[Benny Lodewijk]

btw T_M, have you tried the new F3B BIOS ? Hope it can fix 2T/1T and gain the FSB. I don't have time to test it now. You can download the BIOS here

[[XC] gomeler]

Going to use my 65nm chip to start, will check out the F3B BIOS.

Seems relevant, I don't know too many other review sites that don't compare motherboards. Why pay for a premium board if it I dont have something to compare it to? This seems like a damn nice board

[T_M]

Since when was this thread a review site? Please take your X48 queries to an X48 thread (search!)

I completed one run at 540fsb (8.110s) but cold bugged it foolishly (-110C)
After that i couldnt repeat it.

Time log.... hmm... i'd say last night the chip ran at those volts or similar for about 1.5-2hrs (love how little LN2 it takes on dual!)
Add to that all the air time ive spent at the auto settings > 600fsb.

[Tharshan]

Nice run dude. I'm awaiting by board. I have P45-DS3R here. sucide screen was at 653 fsb with air cooling. used E8400. The CPU still lives after 2,2 vpll and 1,54 CPU termination. it was on air.

[T_M]

Try opening up the Termination, it seemed to be a bottleneck on FSB for me

[dinos22]

Tim
keep your NB volts close to VTT volts
and you will get max FSB

NB volts slightly lower.... like 1.5NB >> 1.54VTT sort of difference

[T_M]

Will give it a shot on air, no more LN2 runs until after July

[youngpro]

haha i love tim, not afraid to throw the volts to get the job done, well done very promising mate,

ill be using your thread as a baseline when i recieve my board later this week... hoping for some high fsb 32m actions...
