Yeah its stable at 4ghz and nothing I do in real world ever pushes the temps that high. But still I think I will prepare to clean the loop next weekend and increase the pump speed to see what happens. Thanks...

I've been running my PLL at 1.63 volts for nearly two years now with a q9550 at 3.8 Ghz ,8 gigs of Gskills over 1100 MHz and 2 hd4870's in Xfire.
there are a lot of voltages elevated to what has been muttered as unsafe here and there around the web and I never shut er down.
It folds 24 hours a day except for time out to play a game or two.
There seems to be a misunderstanding of what is safe and what is not.
Rule # 1 if you think its unsafe then it is.
Every system responds differently to voltage tweaks and you have to live on the edge a little if you want that extra 50 mhz of raw power.
My northbridge runs a tad over 1.4 volts and VTT 1.37 v ..cpu is 1.39 to 1.40
I'm more concerned with stability and registry integrity than where My volts are :D
your dual core will run all day over 500 FSB on this board if you'll just step on it a little and rework that water cooling.
I have chipset, gpu water blocks, and the CPU on the same loop and it hovers around 61C... all four cores 100% CPU utilization in the summer time and 50 deg in the cooler months .
I idle at or near ambients (27 at the moment) and its about 26C in my apartment.
and yea.
Turn that pump up.
If it dosent sound like a low flying airplane next to your computer then your not overclocked enough :cool:
FYI- I run 1.78PLLv and 1.57v NB benching on my MIIF... :D
OK so CPU PLL of 1.54 sounds like it is ok then?
@kwalker, I read that the PLL was bad for Core 2 Duo's but not Core 2 Quads. Thats just what I read from someone in another site that seemed to know what he was talking about. The thread and posts were dated though, back about a year ago or more I think. This machine was stable one year ago with the same exact settings as I posted above, but now it is not. Oh, I just remembered I had to RMA my last MIIF, my bad, so this is a different MIIF, (I ran this MIIF stock since November and just now trying the first overclocks on it) and seems to be a newer serial#, but the same settings are not working. Same CPU and Memory though, as is everything else. Weird
Im sure the extra 500mhz wont yield me any worth while results and since it seems to love 4000 mhz I think I should just be happy with that. The only thing I don't like about this board is that when I reboot, in order to actually boot back up I have to fully remove power from the board between each reboot, other wise she gets stuck in a blank screen not posting. Upon replying power she boots just fine. This is repeatable 100% of the time, its not an intermittent thing.
The E7xxx and 8xxx series processor specs for PLL are 1.5 volts +5% or 1.575 volts and vtt 1.14 to 1.26 volts. The Qxxxx series processor specs are the same but the package design is more complicated with regards to reference voltages and GTL tweaks being that the incremental increases or decreases in gtl ref are directly proportional to Vcc and Vtt voltage adjustments..
that’s why a few key posters in this thread went to great lengths to explain this.
Yes the quad core is sensitive and the guides should be followed unless your not concerned like myself.
Now my QX9650 gets a little different treatment than the inexpensive Qxxx series.
:D
How does this board compare the the Gigabyte EP45?
The issue with the Maximus II and just about every other Asus ROG is the north ,south bridge heating up along with the mofets and power circuits.
most of the time you need to remove the heatpipe and use a better TIM or go for broke and water cool the board which makes the Asus the better board if you can control the temps.
I am more comfortable with Asus and never had good results from Gigabyte.
I guess I just like drama :cool:
F.A.O SkOrPn :
Quoted : " DDR2 spot prices climb back above DDR3 "
http://www.techreport.com/discussions.x/18677
And the last paragraph says...
Thanks for the info. Im waiting just a tad longer for DDR3 prices to fall as low as the price I paid for my G.Skill per GB, the kit I want needs to drop another $30-$50 just to match the price mb for mb. Hopefully this happens by May though... My GSkill is $25 per GB and the Dominators I want are $38 per GB. My G.Skill was the #1 best rated ddr2 memory at Newegg the day I purchased it and today the ddr3 Dominators are rated #1. If Im lucky maybe these will drop to $30 range soon, at least that will be close enough for me. On a side note, I do remember spending as much as $500 for mem kits before tho, lol.Quote:
What about retail? Newegg's cheapest 4GB DDR2-800 desktop memory kit starts at $81.99 before mail-in rebates and shipping, while similar kits of DDR3-1333 RAM start at $94.99. Presumably, it'll take a little while for changes in chip pricing to impact branded modules listed online. Still, DDR3 looks unambiguously pricier right now for consumers.
Does anyone have a Bios Template or settings for a Q6600/B3...
I didn't have any problems with the E8400 installed, but this quad only wants to run stock or on auto.....
I'm trying to get at least 3.0GHz/prime95 stable, thanks-
EDIT: I managed to get it to 3.0, do these numbers look ok? Thanks-

That q6600 B3 will do 3.6 on air but needs more voltage than the G0.
you don't have to worry so much about the termination voltage or north bridge as you would the 45nm quads so you can push that higher if you like the 8X multiplier and higher FSB , otherwise I would use that 9X and go for 400 FSB ,leave the ram at 1066 pushing the nothbridge to 1.4 - 1.45 and FSB as high as 1.36(or a little higher )
your pll can come up a little more also.
as long as your cooler can remove the heat from the CPU you can push the cpu to 1.45 - 1.48 and drop it down until you loose stability ..raising it up small increments at a time until you regain stability.
you can go after the ram later
Please accept my apology if I posted on the wrong forum. My newly finished MIIF is driving me crazy. I would appreciate if someone could give me any idea on how to resolve my problem.
From cold boot the system will turn-on for about 2 seconds then power-off for 3-5 second then it will properly turn-on as normal. Please note the problem only happens when the system is overclocked, also when mildly overclocked.
I am not sure if it was board itself or something else was wrong. I have tried 3diffferent PSUs, first one was Antec Neo 550, then Antec Earhwatts 650 and finally Topower 950w.
Here's the system specs:
Maximus II Formula bios 2202
Q9550
ATI4870
2x2GB Corsair Dominator
2x30GB OCZ Vertex in RAID 0
Topower 950W PSU
Swiftech MCP655 pump and swiftechs blocks.(Works perfectly on my R2E).
Window 7 HP x64
Thanks in advance!!!:)
Not doing that for me with my Q9650 @ 4050mhz. Only does that if my overclock failed, to load the bios' defaults. I would try a CMOS clear (the button at the back of your case, on the I/O plate and manually re-enter your overclock settings. Try with a mild overclock first (100mhz or so).
Hi and welcome. Cold boot - you mean power off at the wall or PSU right? My board did that too, if it turns on, then off, then back on and boots with the desired overclock, its normal IMO. If you leave power on at the wall/PSU then just turn on the PC it should just boot with out the on/off/on cycle.
Thanks Musho,CL3P20 and Cryptik for the help!!!.
Cryptik, exactly as you've described, on-off-on from cold boot and boots fine when psu is on all the time, if that's normal I will leave it alone. :):):)
It looks like this thread has s-l-o-w-e-d way down...maybe people have moved onto other boards, or just lost interest in the MIIF-
Are there any active MIIF threads?
Yeah I think most have moved on to i7. Which I am finally doing myself this week. I cant believe I will have this ROG mobo sitting in a closet though. lol
EDIT: Stupid me I forgot a friend is getting this system the moment I have my i7 up and running, so at least she will continue to be used for many years to come....
