I think i have the SATA problem figured out. I did not get a floppy disk with my retail board. I don't have the jmicron drivers installed.
Anyone send it to me, or post it up here?

fubarswe had sata problems as well, corruption above a certain fsb, are you having the same issues? he switched to IDE and now it works...

i suspect the clock feed for sata is somehow related to pciE or some other clock. did anybody get sata stable at high fsb speeds?
with what settings? what hdd and what sata plug are you using?

[Gunslinger]

My IDE drive is not working either. I never got a floppy with my board that has the driver on it. JMicron support, says to go to mainboard manufacturer for drivers. Don't feel like waiting on EVGA to mail one to me.

[dinos22]

Sorry for the lack of news Dino, but I have been quite busy in my work

I could flash the Reference Board Bios, but I have to force - using /F switch

In fact this bios, with P1 and P2 enable, seems to have very good bandiwth

Here is a result with the E8500 air cooled and the blue Cellshocks

Everest seems to be a bit buggy, if I boot at more than 950 the readings on Read/Write/Lantecy all go very bad in Everst ..this is quite strange, maybe is due to mem multipliers

looks good to me

Tony mentioned that 475MHz is the limit for P1 and P2 but i tested SuperPi which is a much better indicator of RAM performance than everest software

in my tests i am 100% positive that you lose no performance in RAM when booting past 475 as i was booting at 500MHz and 556MHz FSB for the tests with superfast performance in superpi

so do some tests with Pi

also make sure you tighten subtimings (in case you haven't)

i've done some groundwork in my thread which will probably help a bit

thanks for the update mate

with reference boards you have to use higher volts on SB,NB,vFSB when pushing for very high FSB and RAM performance settings

[Tony]

At 475FSB on the older bios files P1P2 seem to get disabled, you see this by the read speeds in everest taking a severe hit, writes looked to be uneffected. Now a few reviewers asked for what ever was happening pre 475 to be given back in options the end user could enable or disable, hence you see P1P2.

Now Nvidia can change P1P2 performance where ever they like, it could be now 500fsb before it gets disabled or 450...its just a simple hidden command but at least we now have the option to manually force it.

I do hope this clears up what i was saying about P1P2 switches.

[dinos22]

yeah true Tony

i am really glad they finally sorted out crappy superpi performance

i did a video on last bench session and posted on youtube
i have the new bios in the video and i go through different parameters >> you can check it out here guys if you like

Nice vid man Love your guitar hero 3 hey?

[dinos22]

lol i'm not a playstation owner but it doesn't surprise me that Metallica and Eric make it on the list as these songs in particular are very very good

[dinos22]

it's a revision 2 beta still

That was a cool demo dinos and im a fan of Eric Johnsons to.

[Fusion2002]

vdroop is terrible on the ref board... thats the only reason I moved to the SIIE. I still can't believe that I paid $150 for loadline calibration



bios 507 at 450 FSB:
PLL - 1.56
VTT - 1.44
NB - 1.44
SB - 1.6

Sexy Sexy... Thanks for the settings I tried them on my SIIE and bam! 450 FSB I couldnt get it over 360 before. im now at 3825mhz. I was stuck at about 3600 for quite awhile.

[webwilli]

wow! what shop?
cancel it and buy it somewhere else!

cool! thanks

computeruniverse - german shop

but, hey, they send me mail:

wir möchten Ihnen mitteilen, dass die unten aufgeführte Lieferung nun fertig verpackt ist und an DHL übergeben wird.

[xgman]

it's a revision 2 beta still

Is anyone hosting this beta bios?

[day187]

Is anyone hosting this beta bios?

anyone?

[Pedropc]

He has just arrive my eVGA 790i Ultra and my Cell-shock, I get the error C1, if someone knows the bios P3 solve this problem? A greeting.

Already said, you've to put some crap DDR3 to boot and raise the vddr, stuck at 1.5v with cellshocks SPD.

[KTE]

Hmm.. been playing and testing with a few setups on air to compare what to stick with using Kenty, Wolfy and Yorky (non-QX).
Tried my trustee Q6600 G0 on Asus P5K3 Premium BPE max stable FSB 440, on Asus P5K Premium BPE max stable FSB 510, Abit IP35-E max stable FSB 480, Abit IP35 Pro max stable FSB 514, Gigabyte P35-DS4 max stable FSB 494 and lastly Asus SIIF 780i max stable FSB 436, not anything respectable by any means especially looking at my $100 board doing better and running cooler. B/w was also higher on the P35. Then I dropped an E8400 into 780i booted 333FSB fine, next stop tried 420FSB stock volts like most other boards did and failed boot. Board never started since, completely dead board. Returned it but am now waiting for some full Kenty tests on the 790i.

Anyone with G0 Kenty get above 490FSB stable? If so, what various volts?

Will never pay that price for a MB, ever, they don't give me money to buy it that I know () but if I do intend to get it, I won't be the one paying anyway so who cares.

+1
Probably if it lowers its price then yeah. How come Kenty got such a low FSB? How high did you go with the vcore?
Do you have any wolfdale or yorkfield to try it with? I would like to see some FSB numbers with the SIIE.

[TheHardCase]

Just fired it up, looking real good.
Started at 450FSB booted noproblem at all on E8400.
NB under 50, its about time.
Vcore is higher then what you set in bios...


I'm very happy so far.

Yeah man I'm wanting to see the same numbers. Don't have the SIIE, looking at this thread before I push for it
Highest Vcore I've put on is 1.67v real and max on every other voltage the BIOS allowed. I don't have (non-QX) Yorky, they're not available here but have an E8400 yep. It never booted with the 780i on oc, killed the board at 420FSB for some reason, chip is fine. Waiting to see a few max Kenty stable FSBs on 790i before I make any move to play with it. Looking below, there's hardly much separating 780i/790i but for DDR2/DDR3 and 1600/1333 official FSB.



I jumped on SE/EVGA 680i when they released and suffered nightmares over 'em for 5 months, 'aint making that mistake again I heard dinos especially touting the 790i as way better in terms of oc/stability than 780i, so I'm now waiting to see results. Kenty results above 485FSB stable and non-QX Yorky above 420FSB stable are what I'm looking for incl. b/w.

My G0 is Yorky enough for me, 1.36v real / 1.344v load for 3.753G stable stock HSF. 1.388v real 3.83G bench, 1.4v real 4.06G bench and around 4280 max at 1.56v air.

Just fired it up, looking real good.
Started at 450FSB booted noproblem at all on E8400.
NB under 50, its about time.
Vcore is higher then what you set in bios...

Great, have you torture tested it yet?

WOW nice fsb with that Q6600.

I am at 475fsbx8 with a Q6600 and the Striker II Formula, 450x9 also stable and was looking to the Extreme to get more fsb but it looks like the old p35s are the best kenty clockers.I have not tried over 475 yet but did boot 490 on a max formula but not stable.

[Big Myke]

So i got my asus SEII from newegg today from the ups.
Let me just say that I'm in the process of rmaing the board. It'll be shipped back to newegg pronto tomorrow morning.

After I did a leak test before I powered up my system. I found out I had a crack in my fusion block. This is not a picture of a cracked fusion block, But I circled the location of where the water would bubble and spew out. What a hecktic day for me. Now I gotta wait another 14 days or less. If I wasn't a watercooling freak I would have never known about my cracked fusion block and I would be probably telling you guys different experiences and O/c results. Sigh. happens right?

[dinos22]

i hope that's a one off or they are going to have some serious RMA problems

[Fusion2002]

Anyone have the SIIE 0709 bios? there is one linked over on the Asus forums but it wont install for me from the bios flash tool, i get a rom mismatch error

[GAR]

anyone have problems with mounting the Thermalright Ultra 120 Extreme, the backplate touches the little transistors, i havnt mounted this cooler because of this, im afraid of crishing them.
