love to see that running IBT or linx ^^^^

I'd give it 1.3 seconds before a BSOD.

What are the chances of D0 doing 4.5Ghz stable? What's the average voltage required? I wouldn't want to spend extra cash if there isn't a lot of difference from my C0.

If you are talking about W3520 4.5GHZ@1.27v, you're wrong, it will be stable the same way...

Depends on what kind of cooling you have. If you're on air, the chances of running 4.5Ghz 24/7 are relatively small unless you're using 100CFM+ fans.

I am talking about all variants of the 920, Xeon or not and 4.5ghz HT on @ 1.27v using IBT or Linpack at full memory usage isn't happening. If I see I'll believe, but you telling me I'm wrong at least puts a humorous spin on it.

anyone seen anything on a 3850a823

its a W3520. Won't be able to test it for at least another week.

I know no guess is perfect, but i'd like to know what i can on it

I am trading someone my c0 and some cash for his d0 is is a 3849A916 batch I heard this batch does very well. I have seen some benchmark it at 4.5 Ghz on a Giga board. So far my C0 will top out at 4.2GHz, hope this new chip is worth the extra cash.

Any of these rings any bells of OCing?

There were also some C0/C1 SLBCHs, but wasn't interested in them...

These are found at my local MC. Anyone with any info at all regarding their OCability, please advise. Thanks...

Obviously, it's all a game of chance, but I would definitely put my money on the 3849B018.

Most 3849B's have proven quite strong thus far, so that is your best bet among the listed batches :up:

It's not 3845B028, though. It's 3849B028 that I have. One digit difference.

Prime blend is harder to pass than IBT or Linx. Although 2 hours isn't much I have been through 3 different processors and 2 different sets of ram and have always needed 2 extra notches of Vcore to pass Prime blend after I was Linx stable. Also have spoken to others that have much the same results, however have never seen anyone post screens of prime blend 8 hours at the same vcore as linx. Care to take the test?

On water with HT off it's a comfort zone for my 920, I can do it with HT on and can do 4.6 with HT off 24/7 but the temps are so much higher that it just seems past the point of diminishing returns for a 24/7 setup. 4.5 HT off is nice temps don't go above 80c usually hover around 70-73 on a 24 hour Prime blend.

It is hard to make a global statement based on a few samples, and apply that to thousands and thousands of other setups, sometimes you can be right...and sometimes not. Took me just few hours with linx to find below OC points, and have checked some with prime, and like on my i940 I record tests.

4.2 HT on, vcore 1.28 pass linx 10 runs of 5100mb, 2 notches less fails 1st pass.

4.3 HT on, vcore 1.31 pass linx 10 runs of 5100 mb (max memory), 1 notch less failed 8th run of same, later confirmed 9 hrs prime stable blend.

4.4 HT on, vcore 1.34 pass linx 10 runs of 5100 mb, 1 notch less failed 6th run, confirmed later with 9 hrs prime stable. Lowered vcore 1 notch in bios, still says 1.34 cpuz load, and still passed prime 13 hrs.

4.5 HT on, vcore 1.38 pass linx 5 runs, 45 mins prime, did not run either longer 2nd temps.

On both my i940 and i950 I need at least same and when tested more vcore for linx at max memory, than prime.

Showing a prime blend and linx stable screenshot together, how would you know they did not simply choose a vcore that both would run at:shrug: I have a 13 hour run with prime blend at vcore that failed linx max memory.

Only way to prove anything would be to video a 13 hour run of prime at vcore where prime passed but linx failed, then keep video going and run linx and capture the bsod. But time demands vary considerably from my interest in the subject.

Since I have now heard quite a few arguing both ways, I assume it is possible for some cpu/mobo/setups to need more vcore for linx or prime, especially given difference between 2 programs and given extra heat of linx.

Or maybe I should get into the internet spirit, and say everyone is crazy that found it the opposite of my setup:D.

LOL I know I pull my hair out every time I see someone claim you can't pass linx when you have a Prime blend stable 8 hours or more. It drives me crazy because it has never been the case for me Linx is rough on temps but easy on stability it is roughly equivalent to Prime small FFT's in my experience and that's with 3 different processors and 2 different sets of ram. Also 2 different mobos... It's not that I don't believe anyone It's just that I would love to see some screenshots showing otherwise to satisfy my curiousity because in my experience I just don't see how it's possible and i've never seen anyone post screenshots saying otherwise so I continue to believe it's not possible.

I don't think this debate will ever get solved though even with screenshots, because there will always be people to claim otherwise :)

Does anyone knows if BCLK is CPU dependent or the motherboard? I mean, what is the factor to run at high BCLK.

Bit of both cpu and board.. i have 4x i7 920 (2x c0 and 2x d0) and w3520 d0 all 5 cpus do 230bclk 32m pi and 3d bench on DFI UT X58-T3EH8 on air and water. I'm probably more board limited than cpu but each cpu required differing cpu vtt, ioh/ich voltages to reach 230bclk straight boot from bios into windows.

+1 on this. I can run prime Small fft's for 12 hrs at 1.32vcore just like linx 20 passes but when I run prime blend I need 1.34v for the same 12 hrs run.

eva2000

for prime95 guys use custom blend or large ffts with 5400mb allocated probably best settings for testing but still fo rme linx and even hyper pi 8x32m might need more vcore than prime95 for SOME cpus not all from my experience with 4x i7 920 c0 and d0 and w3520

Thanks and darn, you've got plenty of i7 CPU's there, lol. Btw, I've got this weird problem whereby I could run Prime stable on 20x200 and 21x197 but the moment I do 21x200, nothing seems to work even if I add 2-3 notches of Vcore, PLL, VTT.

What do you think could be wrong? I tried 21x201 and no luck as well. What voltage do I normally have to add for higher BCLK (above 200)

Same here, tried everything... can't get past 200Mhz on my R2E & i7 920 D0??

However, 21x200 is rock solid 24/7.

I suppose when you mean "everything," that includes bumping up PCI-E Frequency to 110+, too?

I did try 101, 103, 105 & 110. Also eliminated RAM by lowering multi etc.

Strange how I can't post 1MHz above 200 BCLK??

My i940 was cpu limited, bclk max was 215 with normal voltages, 217 max with voltages everywhere from black to red, not a setting I did not try in bios.

My i950 is mobo limited. Boots up 222 bclk with normal volts/settings no problem. 223 is no go. Then raise pcie, ioh, vtt, etc and 229.x boots up fine. Raising pcie above 103.3 or bclk above 229.x to 230 it freezes. I think if I could raise pcie higher could do more.

But like eva said, limit can be either. I think if your cpu makes it to 222, it is probably mobo holding u back, since most mobo on normal settings take a reasonable cpu to that point. If cpu is crapping out a lot earlier may be more of cpu issue. But I have seen most D0 get to much higher bclk than C0's.

Don't think it's my chip. I have had an i7 920 C0, i7 940 plus my current i7 920 D0. I'm yet to see my R2E even post above 200Mhz. Just ordered a Classified, so I'll find out soon I guess. :)

You can boot from bios into windows @ 230 bclk? That is impressive if so. I am unable to boot higher than 222 on my Classified but can go much higher once already into Windows. Is this on the LP UT? might have to pick one up to play with!

A mystery we all have to discover, I guess. The i7 is still very much fill with mystery. Same board and model of CPU, same settings, etc...some users are able to do things others can't.:shrug:

yeah, if all 3 cpus stop at same mhz...that does not sound like cpu problem. post your results with classified when you get it, interested to see what you get.

I believe it's my board that is the limiting factor on my OCing because I have two D0s that OC the same and anything else I try, both would crap out. That factor alone tells me it's my board that is unable to OC the way I want it to. I only managed to get that CPU-Z Validation screen, but if I run LinX (or OCCPT, Everest Benchmark modules, et) both would crap out. The only stable OC I've managed to run on both of them is 21x205 (4.305Ghz). Even 21x210 craps both out. I just sold one of them and now down to just one D0. Am thinking of getting a Xeon to try. Am also thinking of the 3849B018 from the local Micro Center.

Sub-week 50 chips are disappearing quickly, so I wouldn't hesitate to buy it.

Having said that, as you mentioned, your board is likely holding you back so another CPU likely won't give you any gains.

Am I missing something? What has PCI-E frequency got to do with high BCLK clocks? I mean if we stress the PCI-E frequency, it'll affect the graphics card and prolong usage at such high freq. might kill it?

Well, i7 is still new to most of us so maybe this PCI-E freq. has some secret beneath it?

By raising the PCI-E frequency you raise the BCLK limit. Don't ask me why ;)

Sem: Most Core i7 CPUs start to thermal throttle and slow down at 100C. Any temperature below that is fine as long as your computer is stable. If Intel thought you were going to hurt one of their CPUs at this temperature then they would lower the thermal throttling point. The bean counters don't like RMA returns.

Hmm, I just ordered a 3849A832, so I'll be able to do a head-to-head comparison against my 3845B026.

Is anyone putting up a list like we had with the S775's ? I'm getting a brand new 950 tomorrow, though I have no idea for batch. The one I get just has to be good. After 3 normal CPu's I hope it's time to get something decent for once :p

It was the last one, so it's a moot point.

But I was just pick up the phone and talk to stores, resellers, suppliers.

I know damn near every batch available in Canada :D

NCIX.com have 3845B027's mixed in with their billion other D0's, by the way.

I noticed my chip doesn't get hotter with high voltage, I can run 3.80Ghz with 1.25v with max temp 77c, and 4GHz 1.28v my max temp 80c
chip can do 4Ghz with 1.26v, it passed 25 passes LinX but it is not 100% stable, I have to up vcore to 1.28v for 100% stability, also temps are same with 1.26v or 1.28v, is 1.28v fine for 4GHz?
I'm using True120 unlapped

I dont run x64 and i only have 3gb of memory that will change soon tho.

That is all it will let me run in 32 xp it puts such a heavy load i cant do anything while its running with the settings in the picture.

I have windows 7 32 bit i'll try to grab the 64bit version.

If you are only hitting low 70C's that's perfectly fine for Core i7's.

hi Kimofil

I think that I rise in temperature too much.
The way to paint grease was bad.
The heat spreader of it and CPU is not flat.

However, it is good CPU.

That from 2 different chip. The 4.55GHz(3844A704) use 1.475 vtt and the 4.2GHz (3845A935) use 1.38v vtt. Havent test the 3845A935 properly yet but it suppose to clock nicely.:)

No idea but what I know is it is an uncore voltage since I need to change it for a different uncore frequency at the same bclk.
Not sure on other motherboard but on gigabyte I find them independant on other voltages at least for a normal oc.
Usually after I find the final qpi/vtt for specific uncore speed ; I didnt touch it anymore. >>> qpi/vtt I hope that helps.:)

I have a chance to get 3845B220 but there is no data on the net about it. Im just speculating that sub 385 are good clockers, especially B batches.. atm mine 3850A769 is doing medi-core OC of 4.2Ghz@1.32V.. should I take a risk and bought another one and sell this one? only thng that worries me that it will not perform to my expectations

Definitely test the 3845B, you will likely be able to do 4.2Ghz at 1.25V or less.
