Looking to take the 940 to 4.0 24/7 on air, which mobo?

Like the post says, im switching over from intel ( spec in sig ) I was gonna go i7 but the dang DDR3 is way too much. So what I would like to do is take the 940 to 3.8ghz for 24/7 use at least! I would really like 4.0ghz 24/7 use on air. Right now I have the tuniq 120. I wont go water till a good cheap system can be had for $150.

Ok now the board that I need has to be a really good overclocker. The cheaper the better but as u can tell from my DFI LP UT P35 I can spend a bit extra.

Suggestions need really fast gonna make a purchase by Friday Jan. 9th or go to microcenter depending on the board you guys suggest.

To get the best from P II 940 you need either 790FX or 790GX chipset - depends on how you feel about integrated graphics .......

I went with DFI DK 790FXB-M2RSH which is actually cheaper than the 790FX Asus and Foxconn, some GX MB's are actually cheaper such as MSI, GB, etc.

It's too early to say what will be the "best", but for now I can tell you that four of the top five world record CPUZ validations were all on the Asus M4A79 Deluxe. I don't believe it has been released yet, so if you're looking for an immediate upgrade it won't do much for you. The DFI 790FXB-M2RS holds the number five spot. I'm not sure if that one is a new revision of the 790FX-M2RS or just a weird way that board identifies. People have had promising results on pretty much any board that worked well with Phenom though, so that means stuff like the ASUS M3A79-T (available now) and Foxconn A79A-S. In the end though, overclocking is a game of luck. With such a good cooler though, I'd be surprised if you can't hit your 3.8 goal.

use the best cooler you can get a "amdican" mentioned that 5000 be use 1.352 volts on the stock cooler @ 3.0 and 1.344 on H.D.T cooler. o who's going to get a copper true for this puppy ? lol I'll be sticking with my sunbeam CCF.

although I've found it weird that my rosewill z5 ultra is doing better now O_o the heat sink is hotter then what core temps says lol. Temperature probe in the heat sink is reading like 39-41C and core temp is showing 33-35C it's on 9550. anyone got a clue on how that happening ?

sof also said ACC doesn't matter

How about the Foxconn A79A-S.. that holds a coupla high overclocks.. i think i saw the Foxconn Destroyer going close to 3.9..

Nomatter what mobo you get, if the CPU is banana, you will not be able to get such high clocks.

It's a revision of the board with SB750 instead of SB600

I think the best mobo at the moment is Asus M3A79-T Dlx....very stable board

I think If you ordered the cpu on line you are shooting craps, the only way to get a cherry cpu is to hand pick a under 100 batch cpu and even then you could end up with a mediocre cpu based on how well the actual batch came out as a whole.

Kind of like the old saying crap is still crap even if if you put on a silver platter.

As far as the asus board m3a79-t I have yet to see one person with a 940 perform uber clocks on it yet.......or put it under cold, I thinks its the only board I have not seen 5ghz screenies with yet.

Well I could go to Microcenter and get the cpu they price match newegg. I wanted to get everything from microcenter because im such a "i have to have it now" type person.

[/thread]

If you find a 940BE that does 4G on air then the mobo is almost irrelevant.

It looks as if microcenter does not have a decent board in their store. If someone could check out their site and correct me I would appreciate it, because if so I could be trying out phenom2 as soon as saturday.

Best boards that I can find there:

http://microcenter.com/single_produc...uct_id=0277600

http://microcenter.com/single_produc...uct_id=0294809

http://microcenter.com/single_produc...uct_id=0294660

The more I look at the DFI 790FXB-M2RS the more I loves it ( yes it meant to spell it that way ). Since im giving my old setup to my parents for the small amount of $350 im gonna have to wait another 2 weeks unless I can come up with another $60 bucks on my end to get that DFI board which I loves. :)

Don't buy anything but the cpu from microcenter. I spent half an hour getting them to pricematch my 940 yesterday because they don't know what they're doing.

Chew, could you go into a bit more detail on how this batch thing works, why this under 100 may be good etc?

Sure theres a large wafer, they make quite a few chips out of it lets toss a 1000 as a # of chips made. ( Not really sure how many they can squeeze out of a wafer atm )

I lifted this pic off particle for explanitory reasons, hope you don't mind particle.
http://www.pcrpg.org/pics/misc/p2-940-cut-sm.jpg

So the bottom line last 5 digits are what we are looking at here.......Looks like particles came from batch 80000 and is 74 in that batch of 80000, that batch will go up to 81000. The higher the # the further you get away from the center of the wafer of silicon.........The center of the wafer houses most of the "Cherry" chips in a batch as the silicon at the center of the wafer is of the purest quality.

Now getting a chip in the first 80001 to 80100 increases your chances of getting a good chip but there is a catch. Batch 80000 could have been a poor batch to start with and batch 81000 might be better.........getting a low batch # just increases your chances of getting a higher yield chip in a batch even if the batch is poor at clocking to begin with.

I personally don't buy chips unless they are 01 - 50 and where i get my chips from they have plenty of chips to pick through ( distributors warehouse ), I've rarely gotten duds this way.

In 939 x2 I ended up with one that was under #50 from a poor batch and still did 3.0 under a mach 1 24/7 stable, The other chip I got was # 47 in a decent batch and did 3.0 under water and I later went on to take the x2 3800 WR at 3.5g under DI for a short period of time.......( I still have it and plan to take the current 3.7 WR down with LN2 )

Batch is not god and does not mean you will get the best chip in the world but it will ensure you getting a better piece of silicon out of the whole batch, try to think of it as playing blackjack against the casino versus any other game, You odds are higher with blackjack than any other card game at the casino ;)

Last but not least particle nice chip being in under 100, have fun with it.

I could go further into what the other numbers meant back in the day but alot of things may have changed. I may make a new database for stepping/batch.......last time I was able to determine which chips did well under cold among other things.....this time I might be able to figure out something different but I think I will reserve that for AM3 as the 920/940 appear they will be short lived.

Sure he can he's freezing the cpu......I don't think you should be as worried about a board as you should be more concerned about what cooling you will be using to attain your goal. I'm preety sure I will hit 4.5 no matter what board i use, I plan of freezing the cpu however ;) buy a cheaper board , save some money and put it towards a nice used phase change for $200.....

OK can the phase change be used for 24/7 ??


Also I was thinking about just getting the Q9550. At the same time all my friends have Q6600s I want to be different but better! I want the PH2 to really blow theirs out the water. They all run theirs between 3.6 - 3.8ghz.

Also right now I have the Tuniq 120 which I will be keeping for a bit.

Hey where can I get a phase change for $200 quick google gave me nothing that cheap. More like $800+

Got to buy one used. $200-300 should be the going rate for a used mach 1 or mach 2. I picked up a pristine mach 1 for $200 IIRC 2 years ago. Should get you well over your buddies chips.

Yes it can be used 24/7 as long as you insulate it properly.

I have 2 mach 1's I'm selling one but only locally which is why its not listed in our forums, Don't feel like shipping it.

My vapo cost me like $900 2 years ago, as expensive as the current build, but its the third system its been attached to. I actually thought about selling it and getting a triple cascade built, now that would be loads of fun to play with.

MMMMMm cascades were great in they're hey day till LN2 became popular, not really a 24/7 thing, can be done but noisy and not cost efficient :D

Very interesting information chew. Maybe I'm in the minority here that didn't know about that, but thanks for posting!

Just wanted to add one more little tidbit, better silicon does not always equal out to higher oc's, sometimes it will be in the form of a stronger memory controller, or chip capable of higher HTT etc etc.....

BTW great batch guide!

Thanks Chew*.
Great lecture. :up:

would it be worth it to upgrade my DFI 790FX with sb600 to the board with sb750?

prolly be a downgrade IMO

Chew, thanks for taking the time to explain that! :up:

The entire codes on my chip are the same as everybody elses..

0850DPCW
9100082L80280

Meaning I got number 280 which isn't the best. However it's not around the edges (I hope) so it's not the end of the world.

Edit : Since I'm a crack whore for knowledge.... Care to shine any light on how the stepping works? All I know is that some are good, some are bad, but I don't know how they generate the numbers. I remember from Opteron Dual Core that CABCE or such like was good but a couple of letters different was a not so good batch.

It is weird that it seems EVERYONE got an 0850 and I am the only one who got a retail 0848... Also, my last 5 digits are 80062 and my CPU cant clock the cores worth sh*t.

So either I got REALLY unlucky, or the 0848's are pretty bad for clocking the CPU. It seems their redeeming factor is I can stably clock the NB and HTT to 2.75GHz :)

Like I said lower batch # doesn't always mean higher core clocks, could be in the form of HT, a stronger mem controller.

By nature amd's earlier batches aren't always the greatest and they get better with time.

I could shed some light on older cpu's via a database I had created, It's honestly not worth trying to interpret 920/940 steppings because they will be short lived.

I will start a database and try to interpret AM3 however, I am keeping a personal database though of some of the 920/940's people are posting, I'm going to want to compare them with am3 steppings and batches as I get a funny feeling these are failed am3 cores ( ddr3 controller or HT failed chips ) It's the only logical explanation I can think of for AMD to launch an end of life product like this.

So what you're saying is it's not public what the batch numbers actually mean. The four letters could mean days of the week, night shift, day shift and back shift, they could be which QC team checked it. But as far as we're concerned we can't translate it into anything meaningful other than watching which batch numbers are good, and which are not so good.

No they can be interpreted, for instance we interpreted that CDBHD chips had a strong memory controller under cold with 939 and thus did not coldbug or coldbug as bad........You can also identify chips that were failed FX models etc etc.....They definitely are not days of the week/night shift day shift.....there is another line that determines that ;)

Trust me I will go into detail eventually on steppings but first I need a database and results to back up any findings

So AMD label the chips with the this code after they've tested the silicon?

Yes btw the last 4 letter in the stepping doesn't mean as much as you think. the 5 letter stepping has more importance....the chip pictured above has a date code in it as well. It was made in 08, and its week 50 If I remember correctly.....thats what the 0850 part means....So this chip was done around the 14th december.....

Yep, I understood the date, it's kind of obvious. All I know about the 5 letter steppings is the same letters seem to get used, from San Diegos to Phenom IIs...

I created a thread on steppings in effort not to derail this thread anymore.

Dont they cut the cores off from one side of the wafer and work their way through to the other side? this would mean the first cores assembled would be from the outer edge and be first numbered........they wouldnt wait till they got to the center of the wafer then start numbering them......as an example if theres 144 usable cores on a wafer (smaller scale)and they cut from left to right then move in and cut again. that would be a wafer (that looks like a 12x12 tictactoe grid) from left to right and top to bottom the first cores out would be from the edge, the best cores would be from the center 4 rows leaving 4 rows on the left and right and 4 rows on top and bottom

that leaves 16 cores in the very center numbered 53-56, 65-68, 77-80, 89-92.

the highest numbers off the batch would be the last row cut from wafer.

Unless they start cutting from the middle I dont think cores from the center would have low numbers.

This is just an observation.....i have no idea how AMD cuts their cores.

How they cut them out doesn't matter, they could number backwards, the lower batch #rs always comes from the center, I could offer supporting evidence but i fear I would be giving intel guys ammunition so I will refrain.

Ok back on track..... Im gonna take the plunge and get the proc from newegg. As I see more reviews come out im not too sure I will be able to reach my overclock goal of 3.8ghz for 24/7 bummer I know. Here is what I have so far for board, proc, and ram. Do let me know if I went wrong somewhere.

http://www.newegg.com/Product/Produc...82E16813131339

http://www.newegg.com/Product/Produc...82E16820231211

Proc is the X4 940. Im needing fast responses so I can tweak my shopping cart.

P.S. I may go with this board http://www.newegg.com/Product/Produc...82E16813130190 I would save $35 bucks. It doesnt look like a bad board but im NOT a fan of MSI after buying a couple of their boards. Also I may consider that new gigabyte board. Im a Xtreme fan of DFI and ASUS but DFI may be out of my price range this build.

So the new motherboards will be out when AM3 comes out?

sidenote- what are the best air coolers for deneb? Im looking to spend a little extra to get a little higher clock.

Thanks :)

I'm assuming you cant wait? the asus seems like a solid performer especially for fine tuning. From what i hear with the same equipment it gets better performance #rs at same settings.

Best air cooler would be the Sunbeam Core Contact, Thermalright Ultra-120 Extreme, OCZ Vendetta 2. The core contact is the the best performance per $. It is equal to and sometimes beats the TRUE, and costs less. Put a good fan on it though, dont use the stock one. Buy a high RPM delta or soemthing.

Also, the Gladiator cooler from OCZ is worse than the Vendetta 2. It has larger heatpipes and costs more, but somehow it performs worse.

I'm using a true 120 Black and it definitely kicks hiney, I don't think theres a cooler out ther that can beat it if you use a push pull setup.....save the TRUE copper. I'm right now about 10 hours into prime with a Q6600 @3.6 gig running small FFT's to generate the most heat to cure some thermal paste quicker and hottest core is 61C, I would imagine AMD's would run far cooler at 45nm process....MY OCZ vindicator was breaking 80C for reference at same clocks, volts, fans etc etc.

Bang for buck wise though the xigamatex 1284EE or 1283 are both excellent coolers for AMD, for intel they need the add on backplate kit..........which makes them cost like $15 less than a TRUE.

One thing that (we) are running into is the same problem we had with the 9950BEs, alot of the cheaper motherboard's power layout has issues with very high vcore and crashes because the mobo's FETs are overheating.

For example no matter how much voltage or clock speed I use anything over 1.55v instantally crashes. Alot of people like myself on cheaper boards are having this issue ie MSI, Biostar and the like.

I have heard some of the DFI's are less prone to this since they use a digital PWM and Asus is generally of high quality, the same can be said of Gigabyte. In either case if you intend to use a tower sink be sure to have some kind of airflow over the power regulation heatsink as that will honestly be the limiting factor, that and heat as these chips do NOT like getting hot (50c+).

Also these chips seem to have the same quirky behavior in Vista64 where they clock significantly lower than their 32bit cousins. I really dont understand why but it has been well documented.

Finally these chips appear to have "ACC" enabled by default so you do not have to have a SB750 to get the higher clocks, so far the average across all motherboards both amd and nvidia alike are hitting in the same range of about 3.5 on the low end and 3.7-3.8 on the upper end with air.

No I cant wait because the only reason im upgrading is because my parents need a computer now ( PSU on their crappy dell took the board with it to hell ). What would I be waiting for?

Bang for buck wise though the xigamatex 1284EE or 1283 are both excellent coolers for AMD, for intel they need the add on backplate kit..........which makes them cost like $15 less than a TRUE.

Yeah a friend of mine on my recommendation got the Tuniq for his Q6600 and is sitting nicely at 3.6ghz.

For example no matter how much voltage or clock speed I use anything over 1.55v instantally crashes. Alot of people like myself on cheaper boards are having this issue ie MSI, Biostar and the like.

I have heard some of the DFI's are less prone to this since they use a digital PWM and Asus is generally of high quality, the same can be said of Gigabyte. In either case if you intend to use a tower sink be sure to have some kind of airflow over the power regulation heatsink as that will honestly be the limiting factor, that and heat as these chips do NOT like getting hot (50c+).

Also these chips seem to have the same quirky behavior in Vista64 where they clock significantly lower than their 32bit cousins. I really dont understand why but it has been well documented.

Finally these chips appear to have "ACC" enabled by default so you do not have to have a SB750 to get the higher clocks, so far the average across all motherboards both amd and nvidia alike are hitting in the same range of about 3.5 on the low end and 3.7-3.8 on the upper end with air.

I really like your reply. With not " having " to have the sb750 kinda opens things a lot more for me. I would like to hear a few more confirmations on this before I go ahead with it and look at other boards.

M4A series asus boards.

How long of a wait would I be looking at?

I honestly couldn't tell you that but working boards are out there according to CPU-z records. they are in the top 5.....

im thinking i may go with that cheap biostar board and get a better board in a month or 2 when they come out. Actually I may even wait after all and get the Q6600 for now. I was all over the phenoms when it was said u can get 4.0ghz on them with air. But now that user reviews are starting to trickle out that on air most possible stable looks like 3.7ghz. I need at least 3.9ghz for bragging rights.

I have it. I like it. good functionality.
Not for super OCing with hard 4+ hr continuous benching unless you have VRM section water cooled.

Proc is the X4 940. Im needing fast responses so I can tweak my shopping cart.

P.S. I may go with this board http://www.newegg.com/Product/Produc...82E16813130190 I would save $35 bucks. It doesnt look like a bad board but im NOT a fan of MSI after buying a couple of their boards. Also I may consider that new gigabyte board. Im a Xtreme fan of DFI and ASUS but DFI may be out of my price range this build.

Current q6600 are struggling for 3.4, might want to go q9450/9550 45nm......for reference a PH II 940 only needs 3.7 to match a q6600 @ 3.6 in most benchmarks. Its a little different with q9550 I think do to the 12mb cache and small ipc improvements. Don't have one to test but i think the gap is a little larger.
