i'm not surprised. but should be much easier for you guys with higher than 8 multi's. i was playin with my x3330 (q9400) the other night and got a BSOD tryin to boot at 3.9ghz @1.4 vcore, 1.4 vNB and 1.4 fsb termination. i am on air tho, may be possible with water but all my temps were fine at 3.8ghz, cores under 40C idle along with NB and SB. after 2 minutes of orthos i was at 53C for the cores, stoped it then to try 3.9 then went out to the barQuote:

It is really hard to tell - post your Vtt which you are using for 480 maybe we will find some nice values but I am afraid it is really hit and miss :).Quote:

I spent some time the other day messing around with OCing this board with my q9650. I got it stable at 445 x 9 before running out of time to try all of the settings myself, so does anyone have any advice on what to change to get this higher? I've tried just upping the CPU/vtt/vNB volts along with the FSB but couldn't get it stable for more than an hour of prime95.
The rig is watercooled, temps are great (except for the NB getting to 50C under load but that needs a remount with MX-2 on the block), RAM is 4 x 2GB sticks of G.Skill 8500CL5D-4GBPK. RAM volts are probably a little higher than needed, but it's within specs and they're well cooled so I'm not worried about the volts for now

M8 your template is just basic. There is a lot templates for c2q 45nm flying around here you can just read few pages back and you should find at least 3 or 4.Quote:

Give us something to work with.
-----------------------------------------
As a quick guide for sure you would need more Vtt for > than 450mhz, more CPU PLL, more vNB, more PCIe, maybe some GTLs fine tuning.
Disable all in CPU submenu and so on.
All of that with assumption that you ram is stable.
Cheers and have fun :)
lol, instead of just using someone elses settings its kind of a good idea to learn this board yourself and how your hardware reacts.
Maybe I'm weird but I like to know what my money bought, not what others think it can do.....

It doesn't want to go much further than that even with the CPU/NB/vtt all at 1.4v and PLL at 1.6V, so that's why I'm asking for some help.
Which Prime are you stable? if Blend that is ok if small ftt then you should go blend (I am also IBT/LINX stable at 471 but Blend will fail after 3h)Quote:

You might need more then 1.4 vNB to be stable on higher FSB.
In the end simple solution might be setting PCIe to 101 or 102.
---------------------------
BTW I am feeling like I hit the FSB wall with my MF2 - cant make it stable at 469+ There are still few options left but I slowly see end of them.
But those option yeld a hope which I am holding to.
It is shame that I did not have enough experience and time with my first MF2 to do real testing and comparison to my current one.
That is life :)
It was failing 1024 early on in blend tests when over an FSB of 450 (only made a few minutes, at 445 FSB though it passes blend without a problem), so with the volts near what I felt were safe maximums I just backed the speed down to 445*9 and hoped the TIM on the NB would set up better but so far the load temps are still a bit high on the NB
445 it passes 12h of blend? Also what temps r u getting on NB.Quote:

yes, at 445 it'll pass 12 hours of blend with the low volts from the template.
temps are getting up to 50 degrees C (depending on test) with anywhere from 1.1V-1.4V on the NB, which was leading me to think I have a bad mount either on the NB's water block or the heatpipe to the chip itself :shrug: (the temps responded to volts before I put the waterblock on it)

Ok, this may seem a bit odd.... This board is x8 crossfire right?? For arguments sake, say someone put a couple 4850x2's in it... Then started having issues with booting, vid performance, ect...
This could be laid upon said individual as being a fool/n00b/ect...
One would have to assume that the issues are with the PCI-E slots being x8 electrical, and not supplying enough power thru the slot for said X2 cards??
Input/bashing/flames????

Anyone know if my G.Skill F2-8800CL5D-4GBPI can be doubled on this mobo? Like to get a 2nd kit and see how high this mobo will run 8gb

And its bandwidth not power, the slots will provide the same power be it 1x16 or 2x8.
Could also need a bios update to provide full compatability sometimes... or eg ya PSU cannot handle the power drainQuote:

i've found they perform roughly best with around 50ps between channel a and channel b, exactly what value for both is a matter of the board. i use delay 50ps chan a, normal chan b. A p5q deluxe I set up used pretty much the same, normal chan a, 100ps advance chan b.
I run 4x2GB on 1.1v for 1600QP FSB or 1.2v for 2000QP FSB. ;)
diff ics require diff northbridge voltages, probably to do with the diff amplitude more than anything else. microns reqiure quite a bit of additional nb voltage to clock high for example.
Hey !
Yup happy new year to all of ya ppl
I got little present for every one for new year .
It is simple GTL and NB GLT calculator.
How to use it:
First type in desired / currently used vtt voltage as in your bios (or rather the way it looks loaded in Everest for example - but bios one is also working fine)
Secondly put some correction numbers and watch how GTL values are changing (Max and Min values of GTL for given VTT are also shown there).
The goal is to figure out which GTL works best for you for one VTT - in most cases the same GTLs voltages will work for different VTTs or very similar ones (or sometimes not ). So when we switch Vtt we would need to adjust GTLrefs to values which will give same or close to same GTLs as working previous ones for different vtt.
Anyway have fun using it, I created it to make my life easier and it does the job.
PS. There are 2 sets of values to compare between different VTT.
This is a PAIR of 4850x2's in quad here.... That fact isnt gonna kill the bandwidth??Quote:

Don't go by anything you read unless it states its PCI-E 2.0 as 2x 8 PCI-E 1.0/1 would loose performance, this review was very recent.
I would have no doubts running 2 GPU's on this P45, I would not have done so on a P35 though.
That said I do not like Dual GPU set up's and rather have 1 better GPU.
Hi Happy New Year Friends
Any 1 Can Get 500 FSB With Q9550 On This Board?
EveryDay I Try But I Can't Get More 490 On Setup With 1.65 Volt CPU And In Windows With SetFSB 499 But After 20Second Hang In System And Then Reset......
Plenty have 500+ on MFII in this thread : http://www.xtremesystems.org/forums/...d.php?t=197802
Fact is the Q9650 E0 is a better CPU, obv best cores go to them and failed cores go to lower models. ;)
