EVGA 680i Overclocking BIOS Settings

[Theta]

I have poured through hundreds of pages of threads pertaining to EVGA's 680i board.

I've been struggling for several days now to get ANYWHERE with this board, even with the P20 BIOS.

The best I can do right now is 400MHz with a L629B and TeamGroup that were good for 8x500 on a P5B.

Can anyone post their BIOS settings over 400 (1600) MHz?

A LOT of you guys are running 450-500 FSB with Allendale. Post up your settings, please!

alot of the issues with overclocking are coming out of the memory controller being Linked/sync or unlinked, synk or unlinked ratio..

this board is really wierd and nvidia has alot of work ahead of them to make it worth 250 bucks.

its slower than the 965 chipset which makes me really happy i sold my killer DS3. and thats even with the eVGA running the ram at 1111mhz 5-5-5- vs like 8xx 4-4-4 on the DS3 but same cpu speed.

you MUST MUST MUST disable spread spectrum,, all of them.
the HT multiplier i have not had that make any difference i just leave it on 5x
i also lock the pci-e at 115mhz,, all 3 of them.

i think Link/sync is best too from what i have tested. which realllly limits the overclock for 6400/6300's and their lower multi.

i have tried dropping to 8x 7x 6x but it doesnt work, its like the board doesnt care. overclocking still stops right under 1800mhz. and it wont go again until ... until i dont know when... i have tried 2000 2100 and higher and lower and everything in between, and it doesnt work. not for 8,7,or 6x
9x i am able to run around windows at 4ghz but it isnt super stable.

the board is just wierd.
either that or its the first board i have had that doesnt like my ES chip.

Thanks Lestat.

I assume you're talking about being slower in SPI, etc.

3d, gaming, etc. shows better scores across the board, from what I see.

All spreads are disabled (always turn those off).

I checked your suggestions, set Linked / Sync mode, no dice.

To anyone that HAS gotten 450 or above, HOW?!

I am fooling around with the BFG 680i version same reference Foxconn and using P20 bios since Friday. I think I have discovered after 4 days of testing that my issues stemmed from the voltages for FSB, HT, SPP, MCP etc

I was not able to pass Orthos blend very easily and figured it was an issue with memory but apparently it wasn't totally the RAM as I had 2 sets of 2GB 6400C4 to test with.

Thing is during my testing I thought that putting the CPU to default 2.4ghz and setting ram to 800 would help figure things out, what I've discovered at least 90% sure is that the AUTO settings for obviously RAM is way off but the auto for FSB, HT, SPP, MCP are too low.

I've jacked them up a bit but am wondering what everyone else running 400-450FSB has their voltages set to. If people could list or screenshot the voltages that would be a big help. Right now I'm testing with them all at max but I'd rather not leave them there.

[Lestat]

when i hit a a spot where SPI would fail or i'd get lockups or something if i had the chipset voltages on auto i looked at what it said it was and i went up 0.10v higher.
so if auto showed 1.4v i went to 1.5v
that seems to take care of a few lockups i was having but the fSB holes are still killing this board.
the fact also that its totally random that people cna do 450 and higher and some cant
or is it that the Allendales can, as usual make the fSB go higher.?

i also had issues with vdimm over 2.175
right now im at 1111mhz 5-5-5-15 at only 2.15v if i try to make the ram go higher, or up the voltages the system almost always gives me an Error 11. wtf that is god only knows, but it pisses me off cuz there is no documentation to it.
not that th emanual is worth a crap cuz all it tells you is what the Code means, not what the cause is.
i get many post codes where it stops on Extended memory ok well wtf does that mean and what do i do to overcome that ?

Heres...Linked and Synch, 1942 FSB won't boot, mem. @ 4-4-4 -autos..

what ram r u running?

[icon57]

running 470 x 8 with volts on cpu set in bios to 1.575
ram running 1100 mhz 5.5.5.15 vdimm set at 2.4v

...i am not dual orthos stable at all, in fact, i get reboot.
but i can pass all 3d benchies, and game on bf2 for hours with no probs.
...still testing atm

[Dumo]

what ram r u running?

Team Xtreem 6400C3.

[Grinch]

ok thx..

[Theta]

Well crap... Tried your settings Dumo... Same old reboot after settings failed.

Seems my highest FSB right now is 1750, NO more. Been through 50-60 xxx5 FSBs, no different (even though VR-Z said otherwise).

Same TeamGroup, TW - GREAT stuff! I did 1250 DDR2 on my P5B at 5-5-5-12.

[Dumo]

Theta, all cpu function in bios dsabled?

[Theta]

Oh yeah, we're barebone to the max.

About to CLR CMOS, start again to make sure upgrade took correctly.

Not a damn thing enabled that shouldn't be.

Unsure about the LinkBooster, etc. though. It's got my PCI-E at 125 and my SPP <-> MCP Ref Clock at 250...

[Theta]

Looks like absolute max is 1760.

Finally finished all FSBs between 1765 and 2205 ending in 5. Not a SINGLE ONE booted. Ugh...

[Dumo]

Heres...You can try with multi 7X and less vcore too and HPET function disabled...

[Theta]

Awesome effort, Dumo!

However, these settings don't work for my board.

Damn.

I guess there are HUGE swings in these boards. Maybe a new BIOS would help?

[Grinch]

this is the highest I was able to get:

now this is odd...dunno if anybody else has had this happen yet...after that overclock neither 1 of my onboard lan connections work...I mean they light up but windows tells me they have no connectivity...good thing I still have my 3com card..

[Theta]

What were your settings?

Still can't even get there.

You running P19 or P20 BIOS?

I'm going to try to switch back to P19.

ANYONE HAVE P19 THEY COULD SEND ME?

only difference was ram voltage..and running the p20 bios

[sierra_bound]

Are you running 1T or 2T?

Each set-up is different, which is why one person's bios settings may not work for someone else. I always try to find the best settings on my own. I've been switching back and forth between two pairs of RAM. I have to adjust the settings for each pair. One set runs 1T command rate better than the other.

[Grinch]

ram at auto was set at 1T...then again it is only a 512 stick

[sierra_bound]

Sorry, the question was meant for Theta. If he is running Auto, he should set command rate to 2T.

It would be nice if everyone ran the same settings and had the same overclock. Unfortunately, overclocking doesn't work that way. Some CPU's overclock better than others, and some memory modules overclock higher. A few people have gotten higher FSB than I have. But I've gotten higher memory speed. My system is rock-solid at DDR2-1300.

[Theta]

Sierra, always 2T.

Talked to Dumo on the phone tonight for 30 minutes, still no luck.

NOTHING above 1750, and 1750 crashes.

So... Weird. I'm going to flash P20 from BFG to see if there's something fishy going on.

[Theta]

Just flashed the BFG P20 BIOS - works perfectly. Clock testing now.

[The Nemesis]

I'm currently testing the evga and will be testing the BFG next. My Evga stops @ 1860 or 465FSB anything else and I get 11 error code when booting & then system boots with default clocks. Also, during orthos, ps2 mouse and keyboard went wacko. USB mouse worked however & 1850 or 462FSB was 4 hours orthos stable. Currently 2 hours orthos stable 1860 or 465FSB. I'll be posting a thread with bios settings & benchmark comparisons of the two boards after the data is compiled.
