Overclocking troubles

680i SLI A1 *Purchased within first week of initial release

-1.4v core (constant over all QDR for testing)
-1.4 fsb
-P33 Bios flashed
-2.100v on Dominators

Unable to boot into system with 1333 QDR (3.0Ghz) *my target
Unable to boot into system with 1378 QDR (3.1Ghz)
Unable to boot into system with 1400 QDR (3.15Ghz)
Unable to boot into system with 1289 QDR (2.9Ghz)
Unable to boot into system with 1245 QDR (2.8Ghz)

I have never been able to get this board to hold stable ever since I have owned it. I can't even boot into half the speeds that people like to use.

Boots into system with 3.2Ghz 1422 QDR every single time without problems, but is gonna need more voltage and 59c is already quite high.
Problem is my temps run 59c under load.

Anyone know how to fix this?

Now you see why I am dead set against ever buying another nforce board. I was gonna go for a 780/790 along time ago, but after having all these problems I swore off nvidia boards completely for future upgrades.

what's running 59c under load? that should be perfectly fine unless it's your HDD temp, haha.

intel c2q q6xxx series should be able to handle stress test load temps up to the mid-80s and be fine for everyday use outside of crunching.

if you're talking about ioh temps, only thing you can really do is actively cool the heatsink/use an aftermarket heatsink.

I may have spoke too soon about, never buying an nvidia based board again.

I was referring to the core temps themselves
With my current voltage settings, I idle at 43c and 60c (headroom just incase) 58c actual on full load. Should a watercooled system Idle at 43c when OC to 3.2Ghz? I thought WC was supposed to start off in the mid 20's. at 2.4Ghz I idle at 34c even with water.

CPU 1.45000v
FSB 1.5v
Memory 2.200v
SPP 1.45v
MCP 1.550v
HT SPP <> MCP 1.40v

After alot of trial and error I was able to achieve a good overclock, but only on 3.2Ghz
These never work for 2.8Ghz-3.15Ghz on any QDR inbetween. They always work for 3.2Ghz though! 2.8-3.15Ghz the thing won't even load windows with the exact same settings (As soon as its about to load windows it blue screens and resets).
I am still trying to figure out why this happens.

My processor VID voltage is 1.2750v
 
I don't see what the problem is, the chip can handle a lot more heat than it's getting. what are you using to test load temps?

if you think heat is the cause of your instability issue I'm telling you it's not, your temps are fine. the problem is that the chipset just flat out sucks (was using the evga 680i sli for a few years 'till I tore out the board and just started to use it as a frizby).
 
Agreed, you dont have a heat issue. There is nothing wrong with that temp and you cant assign blanket rules to water cooling systems. Different systems and setups have very different running temps and results. Even within identical water cooling components there are variables that affect efficiency such as:

ambient temperature
air bubbles
cooling liquid
cooling liquid makeup ratios (water to antibacterial agent ie radiator fluid,etc)
water blocks
kinks
tube thickness
bends involved in loops
loop path relating to other items in the loop
cooling fans
pump speed
radiator size
air resistance
air flow or lack thereof
improper water block seating
thermal paste
etc etc


Memory related issues with the 680i were always rampant. I would not try too hard to get your head around it. You will only get minor perceivable improvements in any case from memory tweaking. Personally it is almost time to consider other upgrades before you worry too much about your memory clocks. Good luck.
 
i never got my q6600 to 3.0 with my E-VGA 680i bought a cheep asus p5w-dh and hit 3.0 in minutes i believe there is a volt mod on vrzone that makes the 680i a good quad overclocker
