Only an hour so far. throttling on this board has been fixed through a beta bios. So will try to run prime longer next time.

Ben805- been looking at your screenshots and i think i have a similar chip to yours (yours slightly better though), i'm hoping to run this 4.4ghz prime and linX stable eventually. Oh and thanks for testing the 0007 bios for the deluxe ver1 by the way.
LOL That's sick. What are your ambients? You have me thinking about picking up a mora 2 now :ROTF: Got any pics of the setup?Quote:

Your settings should run any app without having to change voltages or compromise TO GET THE NEXT APP TO WORK RIGHT. THEY SHOULD ALL RUN 24-7 STYLIE:cool: LINX is GODLIKE:D
good job..bro I bet if you turned off HT you'd get higher clocks in LinX with that c0.
Nice work everyone, just a reminder:
Prime should be running in your screenshots because otherwise it's rather simple to cheat i.e. just stop Prime then set whatever clocks you want before taking a screenshot :up:Quote:

If you guys wont accept this I can run another 41 hours I will gladly do this again and leave it running this time.
No need to waste your electricity, it's just that when you post screenshot without prime running and temps in the 40's it's kind of pointless. I really wasn't even thinking of your post when I reitereated the prime running part as yours is quite obvious however justin.kerrs 4.6 ht on with 70 degree temps looks as if prime was running but it was not and I have attempted to duplicate his results with water in and water out temps only .5 degree difference and 2 degree difference between water and ambient there is just no way regardless of how many rads he has that he is getting those temps without a chiller or phase setup or something dropping his ambients way below anything normal. Perhaps he is running his computer in an igloo while ice fishing in Alaska?Quote:

No one was saying they dont accept it, but if you download a recent version of Realtemp, ie 3.3, it will probably read specs correctly including Tjmax, tjmax 95 is from adding distance to tjmax + core temps.Quote:

MarcusFoX: RealTemp 2.70 was released before Core i7 even existed so it does not properly support Core i7 CPUs.
RealTemp 3.30 works correctly.

RealTemp 2.70 does not handle hyper threading correctly on Core i7 so it shows the temperatures for the first 4 threads which belong to core 0 and core 1. It does not show the temperature for all 4 cores. The PROCHOT# flag within the CPU has been set for the first two threads which belong to core 0 so the screen shot shows that this core was throttling or reaching 100C, likely during the test. When this happens, the multiplier cycles down to 12. You can't tell from the screen shot whether this CPU throttled once or twice or was throttling continuously for hours but it definitely did some throttling. With early versions of RealTemp there was no way to reset the thermal throttling flag unless you knew how to edit some registers within the CPU or re-booted. Restarting RealTemp would not clear the flag that is set within the CPU. You should be able to clear this flag with newer versions of RealTemp by clicking on the Reset button. I can't remember what version I added that feature.
RealTemp reports 4195.23 MHz. It didn't know about turbo mode back then so it was using a 20X multiplier. 4195.23 / 20 = 209.76 BCLK which agrees with CPU-Z. If throttling was continuous then it would be only 209.76 x 12 = 2517 MHz. With turbo enabled and functioning, it would be 209.76 x 21 = 4404.96 MHz which agrees with CPU-Z. Hopefully some new screen shots at full load will clear this all up.

Yah ok that sounds about right.... because i now when the cpu gets to its tjmax it will throttle itself that could be why.
we'll see on my next pass, im calibrating realtemp right now getting ready to run the test for another 40hours

When pushing a QX9650 hard, they also started seeing some significant differences in the amount of work done for each thread when running Prime95 even during a short run. A 40+ hour run could lead to some large differences in Prime like you were seeing if some of your cores were throttling. This could also be a Prime bug or more likely a Windows bug and how the work load is shared between threads. The picture just above your post above isn't close to any thermal throttling but it also shows some large differences in work accomplished for each thread.
ill read this article, the cpu is running prime right now im about 5 and a half hours in and I dont see a big difference between the work done on most of the cores except core 6-3 which are just alittle bit behind by 1 test too the other cores.
heres a new screen I was able to bump my voltage down abit and up the core speed alittle, I think I have it were I want it now.

Nice overclock MarcusFox. :up:
No one will doubt your numbers now.
98C is getting very close to the thermal throttling point but RealTemp is showing that hasn't happened yet. It continues to report OK for all 4 cores in the Thermal Status area.
To answer that question: the ambient is 26c my computer is downstairs but it right by a water heater and its 160F all the time so it raises ambient around the system 4-5c easy. 4870x2 isnt in the loop and maybe has alittle to do with it but I doubt that since i have a TJ07 and the air flow in this puppy is amazing.its hotter at the back of the system than it is at the cpu were you think the heat would rise to but it gets exhausted by the 2 upper 120mm pritty quickly. The temps are like that because of the ambient.Quote:

Did some HT off testing, did not gain much speed, max bootable B-clock is 221 for this setup. Can get 4.7Ghz stable, but after booting have to use E-leet to bump B-clock to 225, and that doesn't seem like a 24/7 setup. lol
Temps are great when HT is off though.
Is HWmonitor messed up? or is RealTemp off? or is it just the different ways they calc the temps?

Nice oc man.... If i had to cooling I mite be able to match that. on second thought maybe I can we HT off
justin.kerr: It looks like RealTemp is using TJMax=99C for your CPU. Did you make any changes in the RealTemp settings window that would have changed this?
Some of the ES processors I've seen have TJMax set to 92C or 93C by Intel but all of the retail ones I've seen so far have been TJMax=100C. It looks like HW Monitor might be using TJMax=95C.
TJMax is contained within a register within the CPU. I'll show you later how to read this register directly so you can see what program is telling you the truth. Try Core Temp 0.99.5. I'm pretty sure that it is reading this register correctly and it will directly display TJMax on its main window.
Realtemp and Coretemp read same and accurate. Everest only reads cores 0 and 1, then duplicates readings for core 2 and 3 (thread/core confusion by Everest). Hardware monitor is out to lunch.
Justin, nice OC and temps, what are your ambients and can you run everest (computer/sensor) and see watts at load.
I am testing mine on different settings/different fans, ie new gentle typhoons 1850 versus scythe 1600, and trying to get an idea of watts vs temps, etc. Your 3 rads will improve your temps 4C over mine by bringing the 6.7C delta down to ~2C...but curious if you have very low ambients or very low watts cpu or both.
Sorry about off topic post...but will give an idea of temps to expect +/- cpu and setup variability. I cut hole back of my desk exact size of computer to expel hot air to back and prevent hot air from becoming intake air, which decreases my 13 hr prime load temps by few C by preventing local ambients from increasing...which then means at about 20 mins you are near max temps in prime...and any rise after 20 mins is from failure to prevent local ambients from rising...like my 1C rise.
This is in deg C with 4.4ghz, 1.34 vcore, 1.34 qpi/vtt, and loads at 170-185W, max core temps 76C. At 4.6 and 1.4v, temps are much higher, will run that later, this is with PA 120.3, 6 fans scythe 1550 rpms (Scythe s flex F 1600 maxed on controller, always little lower on controller). air intake measure directly over all 3 fans, as air out, then avg.
The 41C delta from water temp to Core temp is only affected by block/tim1,2/cpu diff etc, not by rad which just controls air/water delta.

For example, right now im at stock with turbo mode, so FSB is 133. Is it ok to jump straight to 200 FSB for example?
............
justin.kerr: RealTemp is using TJMax = 99C for your processor and so is Core Temp. To figure out the core temperature, software needs to know TJMax.
Reported Temperature = TJMax - Digital Thermal Sensor Reading
With Core i7, Intel writes TJMax information into each CPU so as long as software reads that information correctly, which RealTemp and Core Temp are able to do, there shouldn't be any issues. I'm not sure what HW Monitor is doing but it doesn't look like it's following the Intel documentation when it comes to reading TJMax which is screwing up the reported temperatures.
rge brings up another issue about Everest. For the longest time, it has only been reading two cores of a Core i7 and then copying that information and presenting it as the core temperature for all 4 cores. I don't know if that issue has been fixed yet.
When lightly loaded, a CPU can change core temperature instantaneously but when loaded running Prime95, Core Temp and RealTemp should be virtually the same.
RealTemp used to do that too when Core i7 first came out but rge's infinite testing helped me make sure that RealTemp works correctly on Core i7. Core Temp also works correctly though in certain situations it might not order the temperature data in the correct physical order but at least it is able to read all 4 cores and it uses the correct TJMax.
AC3421: Once you know what settings work for you at BCLK 200 MHz then going from 133 to 200 isn't a big deal but if you don't know what settings work then you might have to go up in more gradual steps.

My testing is pretty much just firing up Crysis or ArmA II benchmark. If it passes multiple times its good by me. Don't really care for running Pi and all that stuff.
So when I raise the BCLK to 143 it auto resets the computer during Crysis. Its fine at desktop and doing normal tasks though.
Should I up the Vcore more and the DIMM voltage? Obviously this chip can OC much more. Temps are perfect. right now with BCLK @ 142 idle at 25-29c and load in the 40's (While playing Crysis!) We keep our AC on a lot lol, so its cool in the house too.
Also should I keep the QPI frequency setting on Auto? Or put it at the 6.4 selection??
Some more specs - I have Dummy OC off, XMP (Xtreme memory profiles) off (Manually set the memory to its factory 1600mhz when I put them in)
Oh and rig is in my siggy. Mobo has most up to date BIOS wich is a rock solid version.
edit: oh and here is this if it helps. (In Bios the CPU mhz shows 3010Mhz and bus speed at 143)

Ok I upped the PCI-E frequency to 105 and now its stable at 143 BCLK.
But still some tips would be much appreciated!!
Your vcore is probably already higher than needed. You are using 12x multi for ram, so you are probably running into an uncore problem or ram problem.Quote:

mem divider set it on 8, uncore on 16, and put dram volts back on 1.65 or 1.66. And trying to use 12 gb ram, it will be more difficult.
Then leave vcore 1.29x and set qpi/vtt or whatever classified board call it to 1.35v. Then you can probably set your bclk up to 180 or so and start at around 3.8.
And I would drop pcie back to 100.
You might want to ask for help in classified evga thread...terminology/etc little different on my gb board.
Thanks man! I'll post that in the Evga x58 thread too.
ok, so I dont see anything about mem divider in my BIOS, uncore setting is a Mhz selection, nothing about "16"Quote:

Why the hell are the forums so damn slow today :( When I actually have free time to do this shyt.

Looks good on the settings bro but your temps look like they're getting kind of high. I bet you'd break 95C in LinX. Mid 80's is where my temps are hitting under load in LinX with my Xeon W3520 at 4.1Ghz. I'm planning to lap my TRUE and get some higher CFM fans to hopefully drop temps some. These i7's do get hot if you're not on watercooling or lucky enough to get one that runs 4.2Ghz at real low voltage.Quote:

Very true and thank you sir. I am hoping to pickup the Noctua or something along those lines here soon to get the temps a little more under control. I actually got it up to 4075 right now but she will not go any higher and I am not giving it anymore voltage. :explode2:Quote:

OK, my initial Overclock, just put this setup together this week. My goal was just to get 4ghz, and from there tweak voltages/mem/vcard. (I like round numbers, what can I say).
Oddity though with this board. Seems whatever bclk I set in the bios, it shows up as .5 lower. So when I set my bclk to 200, I was showing in windows as 199.5 (3990mhz instead of 4000). So I set it as 201, hence why I'm teetering around 4010. Anyone seen this before?

I just finished my i7 rig and finaly got around doing some tuning. Not the fastest but works for me. During the test my multiplier fluctuated between 20 and 21. BTW I started with Corsair Dominator GTs ram but they died soon after I started testing.

What is with people thinking 4.5ghz is not fast? Your lucky you even got there, or can achieve that with these chips.
scooby, that was turbo kicking in once you stopped prime. Nice oc though on air with HT.
Exactly. A 70% OC is very impressive under any circumstances, all the more when that OC takes you to 4.5 GHz. Given the majority of i7 owners are hitting a wall around 4.2 or less on air, that's a great OC scooby! :clap:Quote:

What vcore are you using for 4.2 and what multi/bclk arangement?
you bastade.....you spelt my name wrong :)
and im core votage was different from the first to the second run I bumped it down to 1.3875. So 1.3875 should be in ur chart on my OC.

Well, this is my first build and my first overclock, so I'm pretty happy with the results so far. It was such an easy overclock thanks to this thread (and others there at XS) that I'm tempted to go for more, but for now I think I start actually using this computer for a while. ;)

Ignore the NB/SB temps, the ASUS temp program didn't play nice with CPU-Z. The NB/SB were running around 43°C before I turned on CPU-Z.

This chip really should have been a W3540, I need higher mp to go further. I can boot and prime at 226, at 227 the mb does'nt even try to boot. I need a new mb, hoping GB X58A will be released soon.
i have the opportunity to get these batches:
3838A431 SLBEJ
And
3911A200 SLBEJ
Any good?

Sniper thats a really nice oc man... gj I think most chips on here could do that speed.. its keepin these puppy cool is the trick.
Maybe not most of them, but I'v certanly seen better chips than this one in theese forums. Cooling is essential though as you say, I'v got 2 tripple rads and ambient in the low 20, that helps.
Here's 8 hours in stupid world.... :doh:

I'm sorry for asking such a dumb question, but... I recently got a core i7 920 / classified MB and I have never overclock anything!
What would be a good "first time" reading / tutorial?
thanks!
