Current 24/7 setting: 3.5 GHz (167 x 21), 1.15 vcore, 1.2 uncore.
It is prime and linpack stable @ 3.8 GHz (181 x 21), same voltage settings.
20 days straight of 24/7 100% cpu... no problems.
Similarly, my alternate 24/7 settings is:
3.8 GHz (181 x 21), 1.25 vcore, 1.275 uncore.
But it is prime and linpack stable @ 4.0 GHz (191 x 21), same voltage settings.
I'm currently running this setting (@ 3.8 GHz) 24/7. To test it out for a few weeks.
I think this is how Intel bins them, but they do it with a much larger safety buffer. (probably on the order of 1 GHz for the 920s and 800 MHz for the 975s...)
Of course, any sort of safety buffer (even if it's just 200 MHz) is unacceptable to most OC'ers even for 24/7 :rofl::rofl::rofl:. But for me, I prefer the reliability. Since I run @ 100% cpu 24/7. :rolleyes:
*On the other hand, my benchmark settings have no safety buffer...
Anyone know anything about the following batch 3845B026, my local PC shop has a few of these and im contemplating grabbing one.
This batch is great, 1 of the best, where did you find them?Quote:

The last one would do 4GHz with 1.264v and 1.35v QPI/Vtt, and the idle temps were around 44 to 46c, and under load they would hit 82c, but this chip @ 3.8GHz, idle temps are 51c, and 88c under load, and this is with less Vcore and QPI voltage that the last processor, and also the last processor was being cooled by a Zalman 9700NT, whereas I have a TRUE on this one!!
I have tried applying more TIM, reseated the heatsink several times, and I have even tested my 2nd TRUE but nothing is making any difference at all, so I take it is just this chip that runs hot???
I am extremely upset about this tbh, because OcUK have given me a replacement chip that is an absolute dog, and I am pretty sure that they know this as well, because the CPU had been used already before I got it, the guy who sent this chip out said to me that it was a brand new chip, and that he broke the seal so that the people who package the hardware for shipping them out would just think that it was an RMA being returned instead of a new chip, but as soon as I opened the box, I checked the underside of the chip, and you could clearly see the pin marks on the contact points where it had been installed on a mobo...
I said to the guy that I had suspected that they had sent me a chip which they knew was a dog, but he never mentioned anything about this in his reply...
I really don't think it matters how much voltage I were to put through this chip, it just isn't capable of doing anything more than 3.8GHz, which I know isn't to shabby, but the reason that I am so unhappy about it is because the chip I sent back could do 4GHz without any issues, and I am sure once I got it under water that I could have gotten it stable @ 4.4GHz, because it could boot into Windows @ 4.4GHz quite easily, it was just the temps got to high under air so I couldn't bench it properly to test for stabilty..
I even got that chip to boot @ 20 x 225 a couple of times, but as soon as I started Prime it would BSOD..
So they have taken my old chip, tested it, and found no faults at all, and they have still went and replaced it with an extremely poor sample, and kept my average chip to themselves...
There really isn't anything I can do about it.. I asked for them to swap it over to my old chip again, but the guy said that it ended up being used in one of their pre-built systems, even though he had told me when he sent the new chip out that he would just use my old one in his test rig himself!!!
So I really don't know where I stand here tbh.. do I have the right to send this chip back and ask them to replace it because of what they have done, even though the original processor was purchased about 2 months ago?
I must be able to do something surely, because they shouldn't have swapped my processor over when my last chip was tested and found not faulty..
Ugh, I have a POS i920 that is highly unstable. Frequent BSOD no matter what I do.
Asus P6T Deluxe V2
i920 D0 3919A509
CPU Ratio: 21
Speed step: enable
BLCK: 180
DRAM: 1443 MHz
CPU: 1.23125v
PLL: 1.86
QPI: 1.35
IOH volts: 1.20
DRAM volts: 1.66

Under load it runs in the mid to upper 70s. The system can last anywhere from a few minutes to a few hours before BSOD. Extremely frustrating.
Ideas?
might give that a try Iam no expert but so far I've raised the bar 300 mhz to 4.4 ghz tweaking thingsQuote:

I've just moved to a new place so my internet options are limited, (hence only testing with stock bios etc). Once i've setup my system properly i'll give it a proper go and see what i'll get, ideally somewhere about 4.2ghz+ for 24/7. Have you done much testing with your chip yet?Quote:

Well, the lowest voltage I can use for 3.8 GHz is 1.20000v with my memory at 1600 MHz... When I used 1.2065v, I got almost 2 GFlops more throughput and nearly a 10 second quicker time per test...
On a side note, the reduction in quality one has to use to get the pics on here is ridiculous. I can barely make the characters out ffs...:down::down::down:

I need to spend some time with this chip and tweak the settings to really find out what it needs and get some screen once my system is back together.
My new chip - Batch 3845B026
I can get in Windows at 4.2 and 4.4 but not stable. I have the ram underclocked right now to test the CPU. If I take the BCLK above 200 should I raise the IOH voltage?

Batch # 3845B027
I started working on stability for a change today on my 920 after months of havin it, LOL. Test ran was blend. I have a mild overclock on my RAM and also gave the uncore a nice lil boost. Here is what I have so far:
http://i269.photobucket.com/albums/j..._4315ghz_3.png
I had to settle for only 6 hours as I woke up this morning a lil before 2am to go to work just to realize there was one of the biggest lightening/thunder/rain/wind storms going on that I had ever seen. Not wise. 4.315ghz was too easy and I am moving on up today. I have a feeling heat will be a factor for me as I have a low voltage/ high temp CPU.
I have 3919A520

I have tested my chip with 3 different HSF's, and for some reason this particular chip runs a full 10c hotter than my previous chip..
46c idle, and it hits 77c when I am running LinX.. Vcore is around 0.954v idle, and it rises to 1.1675v full load..
Temps are a lot higher than the last chip, and I have tried reapplying TIM several times, and like I said, I have used 3 different coolers.
My last chip was under my Zalman CNPS9700NT, and it idled @ 36c and loads were around 69c iirc.
So I wanted to see if it was this particular batch that ran hotter than my previous batch 3851A***, or if it is just this particular chip I have that runs hot. I suspect the IHS isn't making proper contact with the base of the heatsink, because everytime I have removed this HSF there has been a line about 1cm wide that goes all the way across the center of the IHS that doesn't have any TIM on it, and the base of the heatsink is the same.
I am spreading out my AS5 so that it covers the entire IHS, and I have also tested putting an extra blob in the center before fitting the cooler, but the bare line still appears when I remove my cooler, and looking at the IHS closely, it does look as though it dips down in the center.
My stock idle is 37-39 and load is 60-63 running linx. Your temps are pretty high. I'm using an Ultra 120 Extreme, push/pull yate loons 1400rpm, icd7 paste spread with razor blade for my cooling.Quote:

I was looking through some screens of my last chip and then comparing them to this current one, and there is quite a difference tbh...

My old chip @ 4GHz load temps are 86c on the hottest core after nearly 4 hours of Prime95 Blend:
http://img200.imageshack.us/img200/432/87721p.jpg
Idle Temps at 4.2GHz, I never had the chance to play around to get this stable, so I don't have load temps as it would crash as soon as I ran Prime/LinX:

I would definitely say that there is something not quite right with these temps, I personally think that the IHS is warped, and isn't making proper contact with the base of my coolers...
I never had my Ultra 120 Extreme when I had my first processor, so I was cooling that chip with my Zalman.. I would have thought that a TRUE would do a better job than the Zalman 9700NT, but what I find even more weirder about this chip, is the fact that these temperatures are pretty much identical with all 3 coolers I have tested, I think the Zalman was about 1c hotter than the TRUE...
::edit::
Really sorry about the size of these images, I thought imageshack resized them when you upload images!!!
@BLunT
3.8ghz 200x19 @ 1.200v is really not bad, it should do 4.0ghz 191x21 @ 1.26v like your old chip

Hi mate,Quote:

I mean surely if I am pushing less voltage through this chip, it should actually run cooler than my previous one right?
I have tested up to 1.355v Vcore and 1.4v QPI for 4GHz, but when I ran LinX the temps hit 100c on the hottest core, so I stopped testing immediately.
And I have tried running 4GHz using the same voltages as my last chip, but it doesn't even manage a single pass of LinX before it gives me a BSOD with Stopcode: 0x00000101.
When I tested it with 1.355v Vcore, it done 2 passes before I manually shut it down because of the temps.
It must be the IHS on the chip that is warped, because I have tested 3 different coolers on it, 1 of which was the cooler that I used for my last chip, and the temps were still ridiculously high.
As you can see from those pics above my last chip @ stock idled at 34c on the hottest core, but this new one idles @ 50c, 16c of a difference, that is not normal.
Also, I have tried reseating the coolers loads of time, and reapplying AS5 to, infact, I had half a tube of AS5 when this chip arrived, I now have none left because of the amount of times I have reapplied it to see if it was due to there not being enough/to much TIM.
Anyway, as I said, I will be getting another chip pretty soon, so I am hoping I get a decent one this time.
If I didn't care about my warranty, I would just lap this chip to make the IHS nice and level, as I am pretty sure this chip has an uneven IHS, when I look at it closely, it actually looks like it is concaved, and whenever I remove my coolers, there is a line across the IHS about 1cm wide that doesn't have any TIM on it, this happens everytime I have removed my coolers, I tried spreading out the TIM so it was nice and even, and then I also put another little blob in the center before fitting the cooler, but this didn't have any effect whatsoever.
I also tried putting a washer underneath the mounting bracket so that there was more pressure on the heatsink, and this knocked a measly 2c off the temps, which wasn't worth my time tbh.
+15c at idle sounds fishy IMO
see if you can get another one
If you already mount the hs few times and still got worse temp than the old chip given that the ihs is ok then it probably a leaky cpu.Quote:

~30Watt make quite a difference. It certainly not kind of chip you want if you using air cooling.
The only easy method I know to see whether you chip is a leaky one is swapping 2 cpu and watch the watt meter. Or probably you can try use a clamp multimeter on cpu aux power cable..
Thanks for the replies guys.
@iboomalot, I have talked with the retailer, and they have agreed to swap this chip for me because of these issues, so I am hoping that the new chip will run as cool as my previous one did.
@Sparda, thanks for sharing that info with me, I guess this would explain these issues I am having with this chip, although I haven't got one of those things to tell me how much power my system is drawing, nor do I have another chip to compare it with, like I said, it is being replaced anyway, so I just hope that the new one will be better.
It definitely isn't a poor mount that is causing this problem, it is either what Sparda has mentioned, or it is the IHS.
Just got my new D0 today. Same voltage settings as my C0 chip, trying to see how much more I can go. This voltage achieved 3.8 GHz on my C0, so far 4.2GHz on the D0 :up:

I had a chip from this batch, and it was garbage, I had 3910A501, and it wouldn't clock any higher than 3.8GHz, and the temps were insane, I tested the chip with 4 different HSF's, and nothing I did would get the temps down.Quote:

Pretty much the same temps that you are getting when you are clocked to 4.2GHz!!!
Thankfully the retailer has agreed that this isn't normal and is sending me out a replacement one.
I just hope that it isn't anything like the previous one!
BLunTSmoKeR Good luck with your next cpu, it seems that they are not all that bad.
Don't forget to post the results when you get it :up:
@KingsofSorrow, that's my replacement chip being shipped out to me now, and I also ordered my 2nd chip this morning as well, so they will both be here with me tomorrow, I will be sure to post my results on here as soon as I test them out.

I'm limited with my air cooler. With a WC I would esily run it at 4.4/4.5.
[QUOTE=unclewebb;3938042]Scooby: Your screen shot clearly shows turbo throttling. Your multipler is at 20X at full load which equals about 4308 MHz.
At idle it jumps back up to 21X or 4523 MHz but it's not running at that speed at full load.
You need to make an adjustment in your bios to get the 21X multi to stick at full load.
Check out RealTemp 3.30 and i7 Turbo V8 so you can watch your multi at full load.
Unclewebb,
i7 Turbo has EIST grayed out and core 1 throttles. EIST is disabled in the bios of my GA EX58 UD4P. How do I get the 21X to stick?
Thanks
You need to also disable C1e in the BIOS to make 21x multi stick on Gigabyte X58 mobos.Quote:

I am trying to get it o/ced to 4.2GHz atm, but I am having difficulty getting it stable, LinX keeps BSOD'ing with stock code 0x00000124, I read somewhere that this is caused by not having enough QPI voltage, so I am playing around with that atm..

@oggie, I think some people disable HT so that they can get bigger overclocks, and I think that it also requires less Vcore and they don't run as hot neither.
@ Bei Fei, that is extremely low Vcore for 4.5GHz man, is this stable????
I have 3907A360 and also got it perfect at 4.0 GHz but to get it stable at 4.2 i need 1.37v so not worth it.Quote:

Now about HT, if i use my pc mainly for gaming is it worth it having lower (4.0GHz) speed with HT on or should i try higher speeds with HT off :shrug:
Also i know most games/applications use first 2 cores, is there a way of assigning other cores to run things such as antivirus progrems :confused:
I haven't tested this board much. I played COD4 and CS:S for a few hours on that voltage. I am not positive it would be prime for any amount of time though.Quote:

Is this normal??
I didn't think that you could get two chips with identical batch numbers like this, I thought it was only the first part that could be the same, like 3921A and then the last three numbers would be different for each chip...
Batch is just some code number for a large number of chips made at the same time on some fab etc. So quite a few CPUs share the same batch number.Quote:

Sure thing - it's normal. Though they still can overclock differenly (I think).
Thanks for the confirmation guys.
I will be testing the 2nd chip either tonight or tomorrow, hopefully this one is as nice as the one I got yesterday...
@Blunt, what is your CPU VID? you can check it in the bios behind the VCORE
4GHz 191x21@1.264v can you please post full template for all settings?
Thanks
Totally agreeQuote:

Need some help and advice here guys.
I have my i7 920 DO overclocked to 4305 stable. System is per sig.
Here are my settings:
Multi 20 Turbo enabled
bclk 205
vCore 1.44
Qpi/vtt 1.455
CPU pll 1.84
PCIE auto
QPI pll 1.26
IOH Core 1.24
ICH i/o auto
ICH Core auto
vDimm 1.66
I would like to get to 4400 but the vcore is already about as much as I want to try. It seems to me that I have too much vcore for a DO.
I would appreciate any suggestions to get to 4400 at about the same vcore as I am at now. Am I where this chip is going to go or are there settings that I am missing that will get me higher without cooking something? My load temps are ~80c now. I am upgrading to a heatkiller which should give me a couple of degrees.
I will appreciate any help.
@phsinc, I will get a profile of my BIOS for you later on, I don't suppose you have a link to that page that has the BIOS layout, and I can just choose the settings from drop down menus, it is pretty much just like my exact BIOS screens, and it allows me to set it the way my real BIOS is set???
Here is it: http://www.jzelectronic.de/bios/x58.php
Here you go mate.

Hope this helps you out man.
p.s. if there are any other screens you would like me to give you, just ask.
I notice something strange though with my Vcore, I can set it anywhere from where it is in these screens to 1.2914v, and CPUZ gives me the same reading of 1.264v???
Thanks mate, I assume you used 16x uncore?Quote:

1.22500v is what it says in the BIOS for normal Vcore.
And yes 16x Uncore is what I have set mine to.
This chip has much higher VID than the chip that it replaced, my last one was 1.19500v, but it was damaged, the idle temps of that last chip at stock frequency were 17c higher than the idle temps of this chip when it is O/Ced to 4GHz!!! :O
Hey genec you should try raising your nb ioh voltage a tad, also a trick is to set a lower multiplier to boot cause as soon as windows loads it goes to 21. Also try upping the pci-e clock a few to say 105-110Quote:

Hey BLunTSmoKeR how did you get them screens? they look really cool lol.
he copied them from www.jzelectronic.de ;)
I seeQuote:
