I'm convinced this board hates high vCore. Can anyone verify this? It seemed like my 680i could muscle in a stable 3.8ghz @1.68v but this board doesn't want to do much over 3.6ghz @ 1.64v.
Can anyone verify this syndrome? I know anand published diminishing success with higher voltage cpu's, but what about you guys?
iastudio, I have the opposite situation. Where I used to run core at 1.45 on 680i (P5N32-E), I am now running at 1.4v... actually, I'm running higher FSB as well. 1.68v sounds really, really high... that same 1.4v is running my B3 quad at sigged.
That is really nice to hear...i ll give it a try soon.Disabling Loadline Calibration doesnt have any other impact on the system except the stabilty issue?:rolleyes:Quote:

yeah, it is high. I have a early week chip that has always needed a lot to OC. I'll try to undervolt it and see what happens, but I'm talking more about the general amount of voltage needed. Anand seemed to think the board was not the best OC'r for chips that needed over 1.55 to OC. Soemthing about the voltage not being so stable at those levels.
Rise a little bit the CPU voltage.Quote:

Well I hate to admit my Q6600 also has a :banana::banana::banana::banana:ty VID of 1.325 for a stable 3.4GHz I need 1.45v and for 3.6GHz I need 1.565:shocked: I have run 3.8 and 4.0 but havent never got it stable, I'm alittle hesitant to run anything past 1.60v.Quote:

Make some pics Grnfinger! good luck, surely it would help at least 10c drop!Quote:

settings for 3.8Ghz on my q6600 (1.325 VID) *really its 3.798 but who is counting... :p:*
it is prime stable 8 hrs + and load temps are low 70's idle mid to high 30's dependant on ambient air temp. i am on water cooling, specs are in sig... and if you are that picky, im using zalman super thermal grease *cleans off nice and has a brush applicator :up: * sorry no screen shots (not running prime for that long again because i said to myself id quit oc'ing this mofo because it is addicting) but what the hell is the point of lying (yeah im lying about a 1.325 vid cpu) when all we are doing is trying to help each other?
TO Grnfinger - Have you considered sending your cpu back to intel? im thinking about that now, but if u are lapping it, please let us know results thanks
does water cooling the northbridge help any with over all overclocks? ive got a little fan cooling it now. its chilling at around 55c load, from what it was before which if i remember right was around 70... it was even too hot to put your fingers on for too long... stock volts and all. i have not reseated anything on the motherboard because im lazy and id have to undo all this water cooling junk in my case to get to it... luckily i havent put my graphics cards on liquid yet so if any of u guys recommends me doing this as a matter of urgency it wouldnt be TOO big of a problem i suppose
new high is :shocked: should i go higher:shrug:
actually here are some quick pics i snapped off for u guys.
cpu idling

running superpi *very light load and temps are reflecting it, ran it for cpu-z screenshot @ 3.8 really*
http://i48.photobucket.com/albums/f2.../lightload.jpg
thats a silly question.. the answer is always YES :clap: nice cpu dude... im enviousQuote:

I agree, answer is always "YES". However, I'd try for matched higher FSB as the 10x multi is holding you back. Lower to 7x or 8x for same high clock but more FSB. This mobo is great to 500+ FSB with ease. I had the have the Q6600 on another mobo and it is FSB limited to barely 504FSB so the Q6700 should get you a tad more.Quote:

I can run 3825mhz with q6600 needing 1.725Vcore. This mb is very stable over 1.6V. E6600 will run 4g at 500fsb with 1.65Vcore.Quote:

If this was the case, Intel would have to review their official thermal spec docs for X38 and maybe would get some serious troubles regarding RMA's.Quote:

First of all....Good thread! I couldn't read it all, because it'r pretty long, but the first pages are very useful.
What dividers seem to work best for you on this board? I have noticed that 3:4 works very good (400 strap) and that 1:1 it's not what it used to be, but I am curious what works best for you. Thx :)
Hi, Monstru. I find 333 and 266 to give me the best bandwidth (I use Everest Ultimate 4.2 as my bench).
I have attached some 4GB benchmarks. Scroll down for the Maximus (most of them are from P5N32-E). I didn't put the NB strap, but you can figure it out from the ratio.
Best advice is to test it yourself, because your system might behave differently...
I started my computer yesterday and LCD monitor was showing "CPU INIT". I reset the bios, but nothing changed. I called the ASUS technical support and they issued me a RMA # for the motherboard. I wonder what happened since day before it was working fine.
i would but i don't think this ram can handle much more im looking at getting some 4gb kit of 1066Quote:

Either I'm smokin' some serious crack, or there was no 1600 support when I bought the board a couple weeks ago. Neither the box nor BIOS release notes say anything about 1600FSB.
Most any board is capable of 1600mhz support, its just a little more overclocking :)Quote:

I'm definately giving my cpu enough juice and the mobo voltages are even a little high for dual core. When I lower the mobo voltages, it makes things worse. I even loosened the board timings to ensure that wasn't the culprit.
Um... right, I can take a board limited to 1066FSB and clock it way past 1333, but I can't put a 1333 chip into a board with a 1066 ceiling.Quote:

Thank you Dostoyevsky :)
