E6850 L724A105 on Single Stage 4.9GHz 32M SuperPi stable (Gigabyte P35 & X38 mobos)

[dinos22]

hey guys

got a nice chip for a comp i am going to attend next week and did some testing to see if it's any good or what


TEST SETUP

• E6850 L724A105
• C-BuZz Blackbox SS Rotary 1HP
• Gigabyte GA-P35-DS3P F6 bios
• Gigabyte GA-X38-DQ6 F3 bios
• PCI MX400 Nvidia GFX
• 2x1GB Corsair PC10000 week 8 '07
• 160GB Samsung 7200RPM IDE
• 620W Corsair HX620 Modular PSU
• WinXP Pro SP2

Got a HARD FSB WALL at 552Mhz




basically got a 552MHz FSB wall at all multis

Validation with 9x multi (clearly i could have benchmarked at 5Ghz easy aaaaargh)

http://valid.x86-secret.com/show_oc.php?id=249019



SuperPi 1M @ 4923MHz = 10.266s




SuperPi 32M @4.9GHz = 10m 11.151s




4.9GHz wPrime 32M



4.8GHz wPrime 1024M



4.9GHz Hexus Pifast = 19.17s






WATERCOOLING TESTS ADDED (Corsair Nautilus 500)


it's actually not too bad on water either with Gigabyte X38-DQ6

4481Mhz validation

4.3GHz Pi benchable



...... dual 8M SuperPi at 4GHz with 1.44v loaded >> i'd say 3D stable there too but would need to test

Very nice,are you sure you didn't run it any other trouble that wasn't FSB Wall

[Oliver]

Looks good .

Keep pushing it .

[introstand]

Great job...
What's the temp on the last shot?

[dinos22]

Very nice,are you sure you didn't run it any other trouble that wasn't FSB Wall

nah it was the wall

i tried for 6 hours and believe me i tried everything

[T_M]

vccpll mod time

[Harshal]

Very Nice run

[Nosfer@tu]

Great work m8

[Achill3uS]

great run dinos
try the cpu with pll modded p5k series mobo, and I'm sure you could reach the 5G

[eva2000]

excellent stuff dinos

-48C idle is pretty cool there after 32M run @4905Mhz

[Nordling]

my E6850 on lol SS (-18 load) go 4600 only

[dinos22]

guys i don't think those temps are right

my evap was on -48.5C lol

[eva2000]

sounds about right..meaning very nice SS there - 1HP !

my 1/4HP SS evap was around -36.5C for E6850 @4714Mhz for 32M when speedfan reported around -30.5C idle

Very nice chip And very efficient 32M time.

Something colder is needed in order to push up the FSB wall a bit.

[dinos22]

vccpll mod time

i don't think it would do much

plus youngpros CPU has an extra 20MHz FSB on mine
i don't think i stand a chance against pro but i'll give it a shot in the comp heh

DRY ICE on friday for the comp with Gigabyte X38 and Corsair PC10K sticks

but DICE will not max the CHIP i don't think

fingers crossed i can get another 25-30Mhz for some superPi ownage

this chip will bench Pi at those clocks easy on dice

[Sauron_Vie]

great score m8

hitting also a fsb wall @550 on my dq6:

6850 cooled by modded vapo:

[dinos22]

nice one dude




so i changed over to X38-DQ6 and thought i might as well flash to latest bios
so from F3 to F4

my conclusion is DO NOT USE F4 bios if you have this board

F4 is ****ed i could not go past 445Mhz FSB no matter what and even that wasn't too crash hot stability wise

after trying to figure it all out i decided to flash back to F3 bios

and now all is fine



DO NOT FLASH TO F4 BIOS on X38-DQ6 IF ANYONE ELSE IS READING!!!

[T_M]

i don't think it would do much

Worth a try, you might well be suprised mate

[dinos22]

Worth a try, you might well be suprised mate

i'm not a guy that uses soldering irons nor do i have a steady hand
while i could probably follow instuctions and all i don't dare around a few days before the comp starts

as you know gigabyte PCIe voltage is tied in to PLL and i only gained 4MHz FSB by going from stock to +0.35v so it's just colder temps that will help me on the comp

[over@locker886]

Great work!

Lot of chip, have fsb wall about 550

Good luck buddy

[dinos22]

Good

Nice Chip dinos! Makes me think back to the mobil athlon xp days with their unlocked multis.... how nice that was

What I would give to find a way to unlock the multis on a core 2! lol...

Good luck man!
