Asus 680i tweaking and OC guide?

what's ya goal mate . 3.6 ? 4Ghz ? Best bios to use is the 1303, I had good results with the new 1305 but had zero fan control and lost my voltage reading from the NB, SB CPU VTT...so I went back to 1303... Here's what I found out with my E6600 ( for the 333FSB settings ignore those as most settings on auto besides ram and a NB at 1.3 works fine for 1333 FSB GO cpu's at stock) due to the fact you use 4gigs a bit higher an the NB voltage will mostly stabilize things...
Also 680i is a weird incredible HOT chipset as settings can differ much with most users, brands of boards and also mostly due to bios programming... Asus boards aren't s good with quads unless the NB/PWM will be watercooled...

Vcore Voltage: board has large Vdroop/drop so set always one or two settings above required eg 1.4 needed set at least 1.4250
Memory Voltage: board overvolts here and has bad ripples , always undervolt here 1-3 settings eg 2 volt required set 1.9
1.2v HT Voltage: most users have had good results here with keeping it at 1.35 or even 1.4 for 400plus FSB
NB Core Voltage: overvolts : 400-424FSB 1.45V; 425FSB : 1.4v; 450FSB- 1.55V ALWAYS COOL THE NB WITH AN EXTRA FAN !!!
SB Core Voltage: 1.5 works for most overclocks, 1.55 for 400FSB and more, 1.6 for SLI use, to stabilize
CPU VTT Voltage:1.35 for most GO CPU's works mate, if higher than 400FSB go 1.4-45 region

Funny thing is with 425 FSB you can use a lower NB voltage , prolly due to a looser strap kicking in...

Interesting. I saw the same behavior, but I've done a bit of investigation and here's what I've found. Upon resetting the CMOS or installing the BIOS 1305, the voltage and fan instrumentation are all there and working fine. When I run CPU-Z (v1.41), it has some kind of nasty interaction, because after running CPU-Z, the voltage and fan instrumentation in the BIOS is blown away. Resetting the CMOS will restore it back to normal, but you just have to re-configure all your BIOS settings. I don't know enough about the BIOS or the CPU-Z program yet to know where the "bug" resides. My next test will be to see if I can load the BIOS profile I have saved off and see if that restores the voltage and fan readings.

BTW, thanks so much for the detailed post, leeghoofd. Very helpful indeed for a noob like me. I still have a lot of reading to do and much to learn about OC and tweaking in the "modern age of mobos" :p
 
OK, an update to share.
Firstly, I re-tested the CPU-Z issue w/ the 1305 BIOS and it happens everytime. Using the OC Profile save/load allows me to get back quickly.

I would love to get to 4GHz, but am going to take my time. First step was 3.6GHz. Can't get past the memtest during POST. I tried just about every reasonable tweak with the memory voltages and timings that I could think of, but still couldn't get past memtest. This was with all 4 sticks of the crucial 1066 in there.

Here's the CPU-Z summary - you'll notice that the SPD isn't correct - the memory I have installed is actually the PC2-8500 ... odd.

Any suggestions? I guess the next thing to try would be just using 2 sticks? But I've seen where others have gotten the E6850/Striker up to 3.6 with 4x1GB memory...
 
hey Coo Coo, My power supply arrives in the morning, and It looks like we have pretty much identical systems. Love to see what settings you went with for initial pre-overclock. I am totally a newb at home building systems, have been reading MANY boards and have so much info I am almost overwhelmed.

4 x 1gb Ballistix PC 8500
E6850 Processor
Striker Extreme
Windows Vista 64

1000 Watt Cooler Master Power Supply

These timings dont work leeg:
Vcore Voltage:1.3725
Memory Voltage:1.9
1.2v HT Voltage:1.35
NB Core Voltage:1.4
SB Core Voltage:1.55
CPU VTT Voltage:1.4
DDRII Controller Ref Voltage:auto
DDRII Channel A Ref Voltage:auto
DDRII Channel B Ref Voltage:auto

Those settings for 3825 are rubbish for e6850 esp since 1.3725 isnt even a voltage option for vcore - bsods all around until i give it 1.45- but that only allows me to get into windows - to run orthos it takes even more than that, im testing out your 3600 settings right now.

I was however, able to run orthos for 1 hour str8 finally at these voltages on my G0 E6850 bios 1303-

Vcore: 1.3875, Mem 1.925 Timings - 4-3-3-3-2t 2,9,2,7 A, A, A
Ht: 1.3, NB: 1.4, SB: 1.5, VTT: 1.5

Leeg - ya think 1.6v on the SB is ncessary for SLi ?
Running orthos at Leeg's suggestion at
3600
Vcore: 1.36875, HT: 1.35, Ram, 1.925, Timings 4-3-3-3-2t, 2,9,2,7 A, A, 42
Ht: 1.35, NB: 1.4, SB: 1.6, VTT: 1.4

Anyways I see some of the other work youve posted on other forums -- well done btw
My cpu is e6850 - batch - L723B308 Pack Date: 08/28/07
Quick google search for that batch reveals no results! must be pretty new?

Also the striker extreme i am using also had the 4.08 error in pc probe with bios values dissappearing on 1303 - but that was resolved by using pc probe alone with no other monitoring programs such as cpu-z or everest along with it.

My specs - Striker Extreme 1303 - e6850 - 4x1gb Corsair 8500c5 -(micrond9) 4-3-3-3-2t,Trrd:2. Trc: 9, Twr: 2, Twtr: 7. 2x wd raptor 150s, 2x wd raptor 74s, 2x g80 sli (oc'ed and dd water blocked with ACS3 bios), 1x plextor 716a, PC&P Silencer 750W in Thermaltake Mozrt Tx - cooling = swiftech apogee, 2x primochill dual pass 120x4 radiator w/ 2 mcp 655 pump working in parallel with the g80s and finally converging into one to cool the cpu apogee, 10x Silverstone FM121 fans running at quiet speeds (4 on the radiator/exhaust, 5 intake, 1 sys exhaust)- full throttle only used when temps get above 65 which is usually never... Temps reveal 40 idle on the cpu and 50 on the gpus, loads = 60 on all 3(cpu, 2 gpus) in 86 degrees F ambient.

I hate to do this to evga b/c of their great customer support but i had to switch to asus striker after burning thru 3 evga mobos with little or no long term system stability - my only regret is that the q6600 i had oc'ed much better on the evga than the striker imo, but for gaming this e6850 owns.
