The only thing that happens when I power on is the lights light up.
No extreme voltages, no hardware changes.
What could be the cause? Would the mobo lights come on if it where that? Could my CPU be toast? Power supply?
Im anxiety ridden... And Asus's customer support answered and said they'd have to give me a call back within 24 hours due to heavy call volume. Un-freaking-real...
Damn, I know how that feels. Don't rely too much on Asus, their support is not the best there is.Quote:

Hey guys ..
My first time on this great forum .. thanks to help of guys like dejanh & Lukee I've managed to get my Core i7 build stable enough for 5+ mins of prime @ 4Ghz .. but with 1.4V & HT On my temps are through the roof ..
http://i206.photobucket.com/albums/b...600prime95.jpg
http://i206.photobucket.com/albums/b...RAM3047QPI.jpg
But strangely - Core #4 is consistently 10-15C lower under load (at a level I'm comfortable with) .. Core #1-3 are off the chart ..
Idle all good low 30's on all 4 cores (#3 is actually warmest @ idle)
Can anyone suggest if its likely a CPU problem vs. Cooler TIM application problem ?
I would take the battery out and remove the power chord and let it sit for a couple hours.Quote:

lol you are going to RMA a chip to try to get a better overclocker? thats pretty weak man.
There is nothing weak about it. There is still no proof that the chip is not what is faulty, and furthermore, for $1100 American dollars I deserve the best product available. What IS weak is that your chip clocks similar to mine.
From all of my extensive reading I think that it can safely be said that there is no tangible advantage in buying a 965 over the 920 except for some easier overclocking. A good 920 will reach the same speeds as a 965 in most cases. If I were you, I'd try to pocket the extra $700-800 you spent on the 965 and get a 920. That's just my .$02. I wish you luck.Quote:

It may be your TIM placement, or maybe your HS needs to be lapped. That's why I asked what you were using.
From everything I have seen/read/experienced, that is truth. Shame on me because I can afford it or shame on Intel for putting out a 3 CPU's at staggered prices that are effectively the same?Quote:

It turns out that it is an issue with the mobo. Removing the battery did help as it now starts, although, it doesn't restart consistently. If I apply unstable BOIS settings, it will hang until I remove and reinstall the battery. Another RMA process to go through. Both with Asus. First my 4870x2, not the R2E. I suppose cross-shipping would be too much to ask... $(#@*%$)@*$*@#(!
Ouch man! That really sucks the proverbial big one. :( And nah, I took no offense. I understood the context of your comment.Quote:

You have the best product available out of the box. This means that if it's used at factory speed, it is the best desktop cpu on the planet. Overclocking is another thing entirely though.Quote:

But I would never ever recommend it to someone on a budget. Personally I would not be happy with a 920, because I usually like to have the top of the line as a cpu, but I think 99% of pc users should go with a 920 because objectively it is one of the best overclockers and performers out there for its price.

That is pretty damn retarded. $350 CAD more got me literally 266MHz more at stock. That's pretty sad. And yeah, I'd as easily point my finger at Intel. There needs to be a bigger difference between these chips. When you get a i7 940 it should feel like you got an i7 940, and when you get the XE, well, that should be in a league of its own. For now, it's worse than some low end i7s.
ATM, I feel like I donated $350 to Intel.
Did you disable TM (Thermal Monitoring)? If you did, you might want to enable it. 93 will degrade that processor permenantly. It should be shutting down at 90, and personally I wouldn't even let one get over 75, but maybe for a couple minutes during a Chess Bench run or something that was a full load HT enabled with 8 loaded 100%.Quote:

If 93C will permanently "degrade" it how come the Tjmax is 100C?
Who said the Tjmax was 100C?
Realtemp is reading the MSR containing tjmax value on core i7's, so no more guessing tjmax since the value is software readable, tjmax on that one is 100C, distance to tjmax plus temp in C. 100 on all ones I have seen so far.
On another note, Intel white paper quote on running your cpu up to TCC max temp:
"With a properly designed and characterized thermal solution, it is anticipated that the TCC would only be activated for very short periods of time when running the most power intensive applications.... An under-designed thermal solution that is not able to prevent excessive activation of the TCC in the anticipated ambient environment may cause a noticeable performance loss, and in some cases may result in a TC that exceeds the specified maximum temperature and may affect the long-term reliability of the processor."
Here's my OC so far. I'm on air. I can't stay stable in Prime at 195FSB so I'm trying to figure out where to go from here to get the last 200MHz so I can hit 4GHz.
http://members.cox.net/kompulsive/oc.jpg
Personally I'd not want to run in the 90's for long, mine just bsod near a 100C on the stock cooler. But permanent damage if you stay under the TCC, throttling is not even active yet?

I finally found my 24/7 configuration. Thirteen hours of Prime95 is good enough for me to determine stability. Now to try to see how far this thing can actually go. However, it doesn't like the 20x multiplier and the QPI threshold is holding it back. Come on Asus, let me drop that darn QPI multiplier already!

Intel has said that TJMax is not a fixed value. It varies a little from one CPU to the next but they haven't confirmed how much variation is in that number. It's a number they aim for when calibrating but the actual TJMax may be higher.
My personal theory is that it can also vary from one core to the next in a CPU. That's very obvious in the 45nm Core 2 series but I think it's also true in Core i7. There's a reason why in the vast majority of Core i7 screen shots, core0 is the hottest and core3 is the coolest. If TJMax = 100C for core0 then it's likely to be closer to 105C for the average core3. If this was all just random chance then you wouldn't see the exact same pattern with almost everyone's reported temperatures.
Thermal shut down of Core 2 doesn't happen until about 125C and it's likely that Core i7 is the same. I can't imagine that Intel would set such high numbers for TJMax and thermal shut down if they thought people were going to destroy their processors. They wouldn't offer a 3 year warranty and they'd obviously lower these values if they didn't believe in the high temperature durability of their CPUs.
Well said... I think these things are a lot more durable than some people give them credit for, i'm sure when penryn launched Anandtech had at least a full page detailing how much more resilient chips are becoming to death (that's even in light of their high VTT warning which is what gave a few people quite a scare, i wish they'd think twice before publishing stuff like that)
With the temps being reported by most people as acceptable and so much higher than any penryns were run at, i'd say i7 is even stronger.
Of course, in a few months if we're all shelling out for new chips i'll need a hand wiping all this egg off me face.
Im happy sub mid 80's 24/7, depending on the voltage I will need to get me there
Yep. I'm a bit lazy and bought a Koolance Exos-2 LX but I did pair it up with a new Apogee GTZ water block. Considering that my CPU is the only thing in the loop, it's working pretty well so far.Quote:

What made it happen was running 165bclk with 24x QPI and 24x uncore (i was trying to find max stable of both) which were 3960mhz each. This is pretty ridiculous as from what i know they're supposed to top out at 4ghz, but i never expected them to just fry one of my disks like that.
lol you have not fried your disk... you just killed your raid0, happens quite often when you oc.
Thats why i usually use either raid 10 or 5.
If you use suicide raid (aka raid 0) be prepared to have a backup ready. :yepp:
Yeah well, I guess maybe it was karma for giving up on AMD after 12 years with them :p: All in all, I was too cheap to pay for bragging rights of a 965 XE and I stupidly assumed that same thing which applies in AMD world applied in Intel world so I figured the 920 would be low-binned and a 940 would be high-binned (boy did this backfire). This is a lesson for all times, at least when using Intel. Either go low, or go top of the line just for the bragging rights. It's all the same thing anyway, just packaged differently.Quote:

Isn't it weird to happen just from testing 4ghz QPI though? Maybe it was the uncore... This blows because i wanted to start at 4ghz and work my way down until i found my max stable clocks there (based on high multi and lower bclk), i guess i can't do that :shrug:
I'm on the stock intel raid 0 option anyway, i reckon i'll try to figure out how to use the included hardware raid, J micron i think it is.
I'd still be on my blackops if it wasn't for the disaster that was ATI Catalyst :rolleyes:Quote:

I refitted the Noctua today with horizontal mount (fans blowing up out top of case) + smooth cover of paste over whole CPU + thin invisible layer rubbed into HSF side ... brought my temps down 10-15C at load and sub-30's at Idle as you can see ..
Finally happy with the build !!

My excel sheet of my OC's, big difference at 4.1ghz stock multi of 22 versus dropping the multi to 21 at same mhz, or enabling turbo with 23 multi which is another way to lower vcore. All in bold are 12+hrs prime stable (most had linpack run at same time as prime for first 1-2 hrs to try and crash OC early vs late if unstable)...did not record all failures, just ones lasted few hrs. All are 36 (18) QPI, 18 UC for lower bclk runs, 17 UC for higher bclk runs, 1.28-1.33 QPI/Vtt, and 8 mem divider...but I am using 3x1gb so dont need as high qpi/vtt as those with more mem.Quote:

On GGBT boards do we need to manually set qpi and uncore multi's when going for high bclck?
If yes, what would you reco as a first cut?
rge - from your signature - I will try this -
4.2Ghz (200x21) with 1.412 bios LLC, 1.376 load, prime 12+hrs.
QPI/UC/Mem 36/17/8
QPI/Vtt 1.335
Mem 1600mhz 1.64v
CPU PLL, QPI PLL +1
correction - I will try x6 for memory - this the first time as I think I have weeker memory than you.
Those are my exact same settings, but with 1.4v opposed to 1.412 and I'm using 1.66v dimm. I get 1.344 load.Quote:

If that fails, can leave all settings same except change blck to 196x21 for 4.1...if your 4.0 run was at stable vcore load 1.344, then 4.1 on those settings should be close to stable if not 4.2, then you can use ~scaling to find higher stable points quickly. But hard to compare yours to mine, since I have not seen many i965 yet and dont know the effect of dropping multi.
rge - got it, running p95 at your multi's and volts, except vcore at 1.36875 (same as what was stable for me for 12hrs p95 at 134x30).
currently priming at 191x21 - 4.01ghz, temps are lower by approx 5C so far! excellent!
max temp so far down from 75 to 70C
I will let this run for an hour then drop another -1 on cpu v.
Man, you're gonna kill your CPU. Your vcore is past maximum at load (Asus is BIOS + 0.03V at load), and your VTT is way to high too...Quote:

If he says he shaved off 10C-15C his original mount must have not been good as those temps would have put him at or over 100C.Quote:

As far as QPI cooling goes, I guess that means one using high QPI should have solid airflow/low ambient. :shrug: I'm trying to figure out a way I can mount my rig in a glass/acrylic box in my window. Kinda like a window extension of sorts... Think air conditioner, hollow inside. It is winter after all - 12 inches of snow on the ground. Oh, to be young and energetic.
In the manual of the Asus Rampage II Extreme stands that QPI Voltage is green from 1.20000 - 1.39375, from 1.4= oranje.
So 1.35V is maybe not the safe min?
i c on your pictures that you run a QPI voltage of 1.45V.Quote:

greetz
I would bench 2000 ram if I had it, but not 24/7. I just ran 22x182, 17x uncore, 8x mem for spi, everest, pcmark5. Then ran same except uncore at 20x. Then ran same except both uncore 20x and mem at 10x. Wanted to see what had more effect the 20x uncore (necessary for 10x mem) or 10x mem.
I gained ~0.5% in spi and pcmark 5 scores from just increasing uncore to 20X from 17X, keeping mem at 8x. I did not see any more gain in pc mark5 or in spi at then increasing mem to 10x, but had to loosen timings to 10's from 8's, not to mention use high qpi/vtt and DRAM voltages. Everest increased read and copy speeds 6% and write speeds 13% from uncore increase alone. Additional 3% increase from increasing mem to 10X. Other than benching, I wont be using mem speeds over my 8X divider.
For an extra 0.5% speed for 24/7, raising bclk by 1 point is a lot easier all the way around.
All depends what sorta temps you currently getting Idle & Load ??Quote:

Blowing out the back its a much more enclosed space .. smaller fan no surrounding vents .. and the fans dont quite line up with the P6T mount ..
Have a quick look at the radbox link in my sig.Quote:

I continue using it in the present state till I am broken
And you just keep that next to your computer? Is that just for your CPU? What kinda temps do you get with that running?
Very niccee
that radbox is pretty sweet, next time I build I may try something like that...would definitely be better for cooling than my internal rad. As bmilos, would also like to know what temps you get and if one loop for cpu and gpu. Putting one of those in cracked window in winter, not a bad idea, or against a/c vent in summer. Looks like may be easier to work with/bleed etc with everything external as well.
Sounds like a plan. I ran my qx9650 at 1.56 volts for 4.4Ghz for the longest time. I only stopped because heat dump into my room made me sweat like a pig.Quote:

ACPI 2.0 On seems to buy me an extra 20 mins on top @ 40mins ..
DRAM to 1.68V & QPI to 1.35625V got me to 1hr 25mins prime @ 1.4V CPU (Auto had DRAM @ 1.8V !!) .. bumping QPI higher to 1.4V actaully had negative effect.. crashing in 5 mins prime ..
1.45V CPU (rest volts Auto) also does the trick .. gets me over an hour with prime .. but temps are off the chart again ..
this is my first time posting in this thread, here is a link to my results in another forum so that I dont have to re upload everything.
I'm using the components in my sig:
Wprime, super pi, and Generic CPU Bench

3dmark vantage, score is really low, i dont know why, anybody have any suggestions

awesome 3dmark run bro, what are you using to cool the CPU, decent idle temps you have there, pretty good actually.Quote:

Still trying to find the lowest vcore that can support prime stable 4ghz. Currently priming at 1.3250 vcore.
Results so far - it looks like lower vcore (and lower temps) can be had by going to high bclock/low multi.
Data follows - (FYI - linpack was telling me I had corrupted my vista install, currently priming with 32 bit xp).
I've learned the same thing. My Bclk is 211 and multiplier 19 but I'm totally stable at 4.0Ghz with 1.36v. I'll continue to experiment but I still think that something's amiss with all of this. My chip seems to be darn good and I'll just have to find the "sweet spot". :)Quote:

Overall settings are XMP for my Corsair RAM. Any other voltages are left at AUTO.
RAM is running at 1688Mhz(20 passes of Memtest stable).
HT is enabled but with the P6T, Turbo and Speedstep are automatically disabled when you change the CPU multiplier to any value other than the default 20.
What boggles my mind is if I set my CPU multiplier at Auto(20), it's almost impossible to achieve any sort of stability at 4.0Ghz. At 211x19, no problems whatsoever in any stress-testing or benchmarks.
My CPU is under H20 which pretty much eliminates any thermal throttling but the 20x multiplier quirk is very annoying.
What about Vdimm & things like LLC, CPU Amplitude, C-State, ACPI ?Quote:

I'm sorry in a Japanese blog site
I am Japanese overCrocker
Looks like i920, i940, and i965 all then can run with lower vcore for same mhz by using higher bclk with lower multi.Quote:

Any problem watercooling a x2 gpu? My pcmark is 20k by running at 4.4 and doing the dpi shrink, My system is 16,800K if run straight as is.
rge - let us know what you get for a monitor - I am also thinking about getting a new monitor - surely it can't be age - its got to be the monitor!
Dude...I'm on a single 8800GT :confused:Quote:

LOL...I just keep seeing these awesome 26 inch widescreens with much better view of all action on some games...I want one, but my single ultra won't handle the increase in resolution for many games. Need a x2gpu, but want to wait for new offerings.
Thank you.Quote:

Interesting you posted this. I found too that with lower QPI/VTT voltage I end up being more stable. I do not run my QPI/VTT past 1.39V now even for 4.14GHz OC...Quote:

Looks like high bclock is better for oc than high multi.
I can get the same 4ghz prime stable with 0.0875v less vcore by using 191x21 vs. 134x30.
Temps are also reduced from 75 to 66C!
