5022MHz Validation
http://img50.imageshack.us/img50/751...validation.jpg
Are D0's showing same batch-variations as C0's? In case which batch is showing better OC, any pattern is emerging?
I know it is too early to have a firm answer, but I will be able to pick a i7 920 D0 or W3520 from a local store next week and I may be able to choose between different batches. Which one should i chose? Any pattern i batch or weeknr. ( for 920 or W3520 ) i should look for?
215*21 Prime95 :p:

This is only bringing the same circular argument down a peg. Another set of variables and subjective viewpoints rolls right along with it. I could easily say there is no such thing as stability and talk my way out of it. I honestly won't because it is a waste of time and I don't really care enough, but you should understand where I am going here.Quote:

Take the term with a grain of salt. Use context clues to "infer" what the individual is speaking of. Honestly all of us here have a common understanding of stability (well the more knowledgeable anyway), so as long as the subject matter isn't way off, let the term run its course. The catalyst here was when a specific member broke that common understanding with the prime stable claim. He was called out and the brains here know what the truth is. Next!
With that said, let us get back on topic ;). I'm personally waiting on the 975 for my results but I have some choice friends hovering around with D0 on the horizon........
TinTin,
Did I say "plenty of headroom"? Yikes! 5022 is beyond words, and 4809 loaded with a superpi run is
impressive as well. Looks like your chip is golden.
Yup, this chip is excellent with water...4900MHz can pass SPI 1M...:)Quote:

I got mine today thanks to pao_revolt from Ebay. Ordered on Saturday and got it today, now that's fast. Did I mention it was only $257 after the live.com cash back. Batch number is 3849A895. I will post results once I get it installed. I cannot wait.
Great result! What voltages did you set forQuote:

Here is where I am so far, not sure how "Stable" it is, but I am on it right now. :D

Vcore is 1.39v 220x19 with HT and Turbo on.
I got the same exact batch number from him also. Waiting on a motherboard and RAM though...Quote:

The Vcore is not adjusted right now, it will probably go a little lower!

I will have more time tonight once I get home from work. I may have to back it down to 215 for a daily overclock.
Those D0 results are just too nice, looks like too many people are aware of them though:p:, the value of my voltage whoring 940 went down like madness, only got like 10£ leftover after selling it and buying a 920 D0.
I'd say the worst part is that you payed the premium for a 940, opposed to the fact that it's a C0. :sofa:
what are you cooling that with?? a hair dryer?? lolQuote:

Even if these so-called "stability tools" worked, the best they could do is *predict* stability, not guarantee it. But there certainly is a guarantee,
the one we all know about, the three year guarantee by Intel.
okay well here is a link to 5.0ghz stable using your methodology

At what Vcore did you achieve your 4621 validation, and was that with H2O cooling?
I also wanted to know this.Quote:

I don't know, the room temp is like 27-30 degree and I am using Noctua NH-U12P. I can't put more Voltage ATM as the idle temp is in middle 50 and I saw 70 sometimes even not under load.Quote:

Time to lap that badboy. And yes, I'm serious. Cut 5-8C off of my load.Quote:

The best part is that it can hold two fans because it is split, so one fan can go in the center with another on the outside in the conventional location. But even with just one fan it beats all other coolers by a wide margin, so on a "same fan, same fan speed" compare, it beats all comers. See the review on mad shrimps and other sites. It;s designed for either 120mm or 140mm fans. Only possible problem is because it's extra wide, it will hang over the side of the mobo on the EVGA and DFI mobos because they put the CPU socket near the board edge. On all other boards it will be fully over the board.
Well EIST is complicated here. I use the V1 1403 BIOS on V2. Most of the time with HT off and Bclck>=200, the multiplier stays at 21x (which is set manually in BIOS). But I do see a flash of 12x multiplier when cpu is idle. But that 12x is very short, like less than .5 second.Quote:

IOC & IOH voltages as well maybe?Quote:

But that was at 1.488 vcore so your D0 may still be way ahead of me with same vcore.Quote:

What voltages did you set for
QPI/Vtt
IOH Voltage
ICH Voltage
Apologize if this is a common question:
If I buy a new motherboard and CPU, get a D0 processor but a motherboard with and older (pre-D0 BIOS), will the motherboard post? Or do I need an older processor to flash the BIOS?
It'll post.Quote:

Also on the Classified , adjusting the PCIE in bios up to 104-110mhz helped me push bclk beyond 220 .Good luck and thanks again for linking the 920D0.

I feel like I did when I went to the California State Lottery show and was 1 of 8 to get a chance to spin "The Big Wheel" where the worst you could do is win $30,000 and the best was like $9 million. Closest I ever got to being a millionaire. I didn't get to spin the wheel. The guy to me left did. I only won $1500. All of of us that didn't get to spin got $1500. I felt very sad when they were making out the check to me.
Got my i7 920 from newegg. It's a SLBCH "C0" :(
Think I will just keep it, maybe get a 950 once it's been out a little while or possibly a 920 D0 guarantee
Don't sweat it... Some of the last C0's clock quite well...
Max overclock for me and on air so far. I live in Oklahoma and it was in the 70's when I did this. Windows opened so no chilled air here. Vcore was 1.456v.

That is not possible...it's a c0!!!
That is possible indeed, I did it on DICE and I had another friend with i920 did the exact same result on SS.
@PytonOrm, your stepping is actually the early batch of the i920, the late batch numbers are 3841-3843.
Let's not forget eva2000, who has been doing it on air since last year ! If you look at the very early c0's, they clocked like the early d0's, the unanswered question is whether most d0's will continue to show the same pattern or will settle in at the 3.6-4.1 range like the majority of c0's ? Time will tell !
These are indeed impressive results, even for DICE. My C0 week 36 did same clocks/same superpi run, only I needed 1.488 volts. Then again, I was using a 2.5 year old air cooler. Still, 4660 Mhz at 1.38 volts is mighty fine! :)Quote:

hello
I have a 920 D0 3847A and a 21*194 I need to vCore 1.25V in bios (and with a Rampage II Extreme that is in full/load ~1.29v) to be stable under OCCT, CPU Stress MT, etc.. ..
with a lower vCore, OCCT, CPU Stress MT or Prime95 which closes on its own or BSOD (reboot)
1.29v to be stable at 21*194 (HT on) you find that good or not?
thank you ;)
