mine just rebooted after more than 45 minutes in prime small :( 4100 @ 1.45v, coretemp was ~ 48C
Ehhh maybe, I tend to say that was a bit much vcore for "most" C3's but just not that particular chip.
Treat each chip like an individual, not a collective, never know what a chip will like/do until you try. A good gauging point however is a chips ref volts......
I would say less than .200 over stock is fair game for air and water.
That chips ref voltage was 1.40 so still in my personal safe range, I find most chips stop scaling after +.175 and seems C3 has a wide scale for ref voltage.
I have seen 1.325 up to 1.40 so the range of most peoples maxxed out clocks are going to be on average between 1.50v to 1.575 providing the chips have voltage tolerance.
i have with 955 the best risisng with 1.45V (up 3850 MHz). Up next 50Mhz i need next 0.05v (1.5V)
chew*, does voltage tolerance make a chip desireable for use with extreme cooling?
My 0942fpmw c3 isn't great for my water rig. At room temp with .5 hour blend: 3.7@1.4, 3.875@1.5, no go at 3.9@1.55. At 0C in window, 4.118@1.568 succeeded, and 4140@1.632 wouldn't complete, but didn't fry it (phew!). I'll probably sell it and try again, but want to make sure it's not of use to someone who uses much more cold!
Grinder,
To be truthfull I have not been able to duplicate any proven method of a good cold chip........I have had great air chips do great cold and other great air chips be total crud cold. Same goes for bad air chips, some do well cold some are just crud all the way around.
Still searching for the magical combo and what makes a good chip a good chip but so far it has always been put a chip in and freeze it and test it thouroughly throughout the entire voltage range.
Seems the most important factor i have found is voltage tolerance. However that alone does not make a chip a good chip.....also have noted some air chip with wicked voltage tolerance all of a sudden hit a wall @ 1.7v cold. The best chips i have have had have have 2 common factors. They scale well and have voltage tolerance however this can only be determined once you hit it with max cold.
Still trying to break it all down to a science but so far my data is all over the place and there is not much for consistency.
The chip in the above Prime shot does 6.5 max 1 core. I have another chip here that does 6.7 on 1 core yet trails in prime on air by 100 mhz.
Best I can say is I know what properties to look for when cold but they can only be determined accurately when cold, it's kind of hard to explain but went through a few chips when at the recent michigan event.....I knew right away when I found the "right" chip so much that I didn't even bother testing a few other chips.
So, it has some potential, but the proof is in the pudding. Errr, popsickle...
Thanks for the info! :up:
Talking 'bout potential...
http://img.photobucket.com/albums/v6...Prime41GHz.jpg
No icewater or cold outside temps, just 20ºC ambient and regular watercooling.
So, shall i try for 4.2GHz with some more volts? :)
ik zou zeggen leef je uit tot 1.55v ofzo :p:
Zeus: of course, jump at 1.6V and 4.2 or more is yours :)
64NOMIS: I wonder one thing....most memmorys is rated for Intel platforms and the will not work same on Amd platforms. Now i dont yet have any DDR3 platform to test sticks, but it would be great if Macci or someone with help of Corsair, Geil, Gskill, Muskin, Kingston, OCZ, Crucial , Adata could show what sticks works great on the Amd platform with the new Amd C3 cpus. Its much gambling now to get sticks that works good.
Ok I think i'm done with this chip before it meets an untimely demise. Seeing as how I promised it to someone that would be bad.
Prime really isn't my thing but I just wanted to see how it would do with an optimized ram and NB clock.

http://chew.ln2cooling.com/qdig-file...g_cine%202.JPG
Nice work there chew. What cooling did you use for that?
Awesome job there chew*, not just a nice speed on the cores but nice NB and ram speed/timings as well! Is that Elpida based ram?
Air cooled?
I have looked in the "Xtreme Bandwidth" forum and "Best DDR3 Memory for PHII" but its not enogh...also if i look after memmorys in Sweden in stores the info is not enogh. Maybe you dont see the trouble but its not few that have it.... its many.
All i want is to help users to choice right memmorys, thats work great and clocks great with Phenom II C3. Brb see if i did miss something in another forums.
im at my parents for the holiday but when i get back home sunday its supposed to be a little cooler in MIL next week so we'll see if i can crack 4.2 on air... i was prime stable for 25 min. twice with 60*f ambients so i think if i can drop them 10* or so i should be able to hit 4.2,,, 20-30* and maybe 4.3 ;)
I think i've met the limits of this chip. 4200MHz Prime blend rebooted after some 3 minutes at 1.52Vcore. Raising Vcore to 1.55V made it reboot even earlier.
Then i tried 4150MHz, 2 cores error after 13-15 minutes, this might be CPU-NB related so i think with some effort i might be able stabilize that.
Furthermore, tested some SuperPi 1M, got it to do 4360MHz but time wasn't that good due to "low" NB. 15.719sec iirc.
Seems like the NB on this chip isn't great, 2.6GHz is stable with 1.18V but 2.8GHz requires heaps more, well over 1.3V
I have to do some more indepth research as everything was on the edge so maybe i just overlooked something.
4.1GHz Prime blend stable is nice but only with appropriate NB speed.
Then again, i'm not complaining with 4.1GHz fully stable with normal ambient temps. :)
You know what is even cooler? The Smart Profiles in AOD :D. I been modding the XML file to allow my custum clocks for my 965. I finally got CoH to work and add some others. I don't have any memory that works with BE profiles, so i don't even mess with it.
Edit: Plus, it work great with CnQ enable. Just like a "Turbo Mode". And since it holds the clcoks, there are no performance hit whiel running the apps due to throttling. Then releases the clock upon closing the app.
Ok thanks for the update. I keep checking! Have my 8's running 7-7-7-21 1600mhz.
Playing with multiple chips atm........
Those of you on water wanting to find your max.
I have found a preety cut and dried pattern, you can "shoot from the hip" with +.175 over default vid........and just test your chip from there, on occasion a chip will get mad and want a tad less or on rare occasions you can use more......but i'm def seeing a pattern.
Chip in above testing was default 1.375, liked +.175 and had just enough tolerance to handle that .025 more. I'd reccomend for most to stay at +.175 max though.
instaled, with 500W seasonic (maybe il must it upgrade to 650W?)...to tme i have a troublw with Cinebench at 4 gHz only?:( Why? PUS with 2x 17A is bad for higher voltages? Or is not good my chip C3?
Lastviking: tomorow il test it. To time, i can good stability at 3716Mhz and 2600 MHz NB with 1.375V, 3817MHz with this voltage not passed all time. Yesterday i havent much time-only 2runs Cinebench, qucikly at 4080MHz with 1.5V and in x64 at 4GHz with 1.488V. And than only 2x stability test with default voltage. Think, i need more time to test. But even so, according to the benchmarks, think that the chip will be nothing extra. Can me AMD change it?:)
Ok now to go by 64NOMIS' rules:
System:
Asus crosshair III Formula
965 C3
2x1 GB CSX Diablo ram (D9GTR)
Silverstone DA800 PSU
Watercooling:

I tried 4161MHz but it rebooted after several minutes, over 1.5V makes one or more cores error. :shrug:
nice clocking there Zeusje.
My wallet is burning in my pants or is it something else. I might get me one of those C3's.
Just got back from the HCC where they have some nice setups running at the hardware.info stand.
I'm running C2 on max 3,8@1,45V stable in W7 64B.
4Ghz is no go with 1,5Volt with my setup.
P.S. do you have the EK full board installed?
Keep up the ante.
Hey there,
If it's something else burning in your pocket it's asking for immidiate attention! :D
I could get my 955 C2 doing 4GHz Prime stable but ran it 3.8GHz daily.
I don't have the EK fullboard block on it, i don't think adding the extra restriction is worth it.
And besides, the board barely gets warm. Gotta admit that the block is a great looking piece though. :)
Hey Dave,
I cannot comment on the Apogee GTX, i think that is Swiftech latest block with the micro pin design and alternate inlet?
I can only say this heatkiller took off 1-2ºC idle and about 4ºC load compared to my old D-tek FuZion block.
I have the delrin LT version and i like it a lot, been trouble free so far. ;)
And the price for the LT version (not to be confused with LC) isn't too bad either, at least not here in europe.
Sorry guys for little OT, but 7GHz+ PII C3 under LN2 not LHe must see !!!
It seems there is newer XT than GTX. but there is no plate for AM3+ yet. According to Swiftec, XT has about 3degrees improvement above gtx.
Nice to see you using heatkiller. v3.0 tempts me really after seeing madschrimps intel i7 core test :)
I wonder if Phenom and core i 7 are similiar regarding heat dissipation for water blocks?
still not quite cold yet for milwaukee standards but cold enough for 4.2ghz ;) (around mid 40's F outside)
still using xigmatek s1283 with scythe ultra kaze 3000rpm for my air cooling and this is on windows 7 64-bit

Wow, you like volts lol.. Nice air run:up:
Looks like we are approaching the end of round one. Any last entries before we move on?
Then we are agreed. All will WAIT AND WATCH for Titan7171 to post his chilled water results. This will mark the passing of this half and the start of the second and last half for this thread. We will take a tally of all those who have fought with air and water and their efforts will not be forgoten. If you wish to be counted among those completing the first, then know that the hourglass is turned and your time runs out.
With 8ºC outside temp i had to give it a go:

And after 5 minutes idle:
http://img.photobucket.com/albums/v6...s/4221idle.jpg
Systems specs are the same as before, outside temp 8ºC.
Overclock: 201x21=4221MHz :up:
Just some observations:
The chips stops scaling after 1.5V, regardless of temps (i'm talking temps above 0 ) and CPU-NB seems pretty weak compared to my old 955BE C2 and even compared to my old 940BE.
I can't stabilize 2.8GHz with reasonable voltage where my old chips could both do that easily.
Ok, that's a done deal now, ready for the next part Simon. :)
Nice one Zeus! :)
Edit: I like your mousepad ;)
Nice temps Zeus.
I have the same limit with cpu-nb, for 2800 it just needs too much voltage.
Thanks guys.
It was nice to have mother nature helping me a bit even though temps werent that low.
It surely helped me out for 1M:
http://img.photobucket.com/albums/v6...tory/15359.jpg
Efficiency isn't great due to lowish cpu-nb, hopefully subzero ambient temps might see me breaking into the 14's. Not sure if this chip can do that as it's allergic to voltage over 1.52V. :(
Seems like this new C3 is a hit and miss, some people having good success, some not as good a C2, i just ordered a 965 C3 hope it out does my C2 :shrug:
zeus, nice picture! can I see more pictures of the watercooling things? :up:
64NOMIS, thanks. :)
Tomasis, all the info on my system can be found in this thread:
http://www.xtremesystems.org/forums/...ight=murdermod
Some things have changed since but the watercooling system is almost the same still.
I am so jealous of you c3 owners. 955 c2 FTL . Nice work Zeus
So here is what I managed with some cool air. Tried hard for 4.2ghz, but it wont happen without more coldness... But really a fun chip I must say :)
Gigabyte GA-MA790FXT-UD5P
AMD Phenom II 965 BE C3
2x2gb OCZ Platinum (rated 1600 7-7-7 1.9v)
CFT 1200G-DF 1200W
Windows 7 32bit Ult
The cooling was done with a lapped and pressure modded TRUE copper with two ultra kaze 3k rpm in push/pull. Paired with an awesome-looking cardboard and duct tape air-tunnel, and a 220v 120mm fan feeding fresh air.
Measured temperature at CPU fan intake: 14C

What say you?
I rode many times with the AMD Phenom II X4 955 BE and the C2 revision they will not soon be forgot. It broke the 7GHz barrier. They benched 3D like their masters were at their back! It's north bridge and memory controller flowed like stallions in the field. You own a piece of history my friend and at 3.8GHz you are well off indeed!
And if still you despair, you could always sell it, wait a few, and buy something new...
I'm still at work I get out at 1am and the fun begins at about 2am, it's going to be a long early morning
Sometimes people so stress themselves on what they don't have that they miss out on what they do have. I know, I've been guilty of that myself.
It's the pursuit of "forbidden fruit"..
I've been reading about the 965's and they sound nice but the 940 i have here works perfect. Smoothe( yes, that word again) runs cool,stable and does what you want from a machine..Dependable..
Now when are we going to get one of these threads on dual socket machines?:D
Look at the interest there was on the Supermicro board for those new cpu's you guys are bringing out.
Suggestion: Send the IHS measurements and hole spacing for the HS to some of the big aftermarket HS makers ahead of time like ThermalRight so they can do their magic and have good HS ready when the boards hit the streets.;)
64NOMIS:
Hey bud, I know this isn't exactly what you asked for, but I did put this C3 under water and have spent many a night already shivering with the window open... :yepp:
If I had Titans Rad, Equinox's Chiller, or Charged's garage I'm sure I could do alot better... :D
I posted my ambient AIR temps here:

Great results guys, C3 rocks!
I guess this is it for the first half?
Curious what the second part will bring, i hope no 3D test, i only have one HD4870.
Ok, one more kick at the can. -2C here last night, so set my water rig in the window again (see previous pics, and I have to say again that I really liked your plank Simon!).
I'm not going to beat anyone's scores with my 0942FPMW (thought of selling it but it's still faster than my 550be, which I've been hanging on to as a backup). It bothered me that my 4118 run during the duel with Lastviking was at 2000 nb and 1333 ram, so I bumped those up rather than try to squeak out a couple more mhz.
I ended up with a .5 hour prime95 stable 4108, 2739 nb, 1660 ram @ 7-7-7-21 1T 28 90. I'm using it day to day at ambient room temp @ 3875, 2750, 1666 same timings. :up:
Screenies are 30 min load, aod settings, and 5 min after end of test. CPU voltage is 1.5875 (+.1 in bios doesn't show on cpu status). I ran it to 1.6375 trying for 4125, but it would reboot after 10 or 15 min.
I set the cpu to 3700 and stock voltage, and determined what I needed on cpunb for 2000, 2200, 2400, 2600, and 2800. I'll edit those in when I get home (working again lol).
Updated:
2000@1.025, 2200@1.075, 2400@1.125, 2600@1.225, 2800@1.35
IIRC, I was at 1.35 for 2800 and 1.225 ish for 2600, which means I'd probably need 1.4875 or more for 3000 the way it was scaling. I may try at 2900 just for fun, but it seems a nice balance at 2750 and 1.325 for day to day.
Sorry to hear that you are without your C3. Plan to try again when you receive your new chip?
Yeah, my single 4850 will be a hindrance in 3dmark. Maybe I can cf it with my old xt1950 pro or x800gto2 :horse:
I need a new mobo I have to push 1.45v on cpunbv for 2.8ghz nb
For those who wish to continue down this path. You have elected the way of pain!

Chapter 2 Guidelines Posted
That is the experiment. Added also the CPU temperature graph to see how temperature rises and crests through the test.
It's an opportunity for some DRAM tuning and to see how much of a hurdle that a fixed multiplier creates with a lower (10X) and upper (17X) bound.
"five minutes to twelve" i add my experience with 0942 EPMW. AIR, cooler master Hyper 212. Im back from work and very qucikly and in chaos i run PRIME (but i forgot changing NB multiplier at 13 in BIOS). So only 3970 MHz with 1.488V (aod setings voltage is not correct) and 2400+ MHz at NB. Ambients 20C. Its not maximum, max i have 4010 MHz with 2672 MHz at 1.502V. Ok, now some screens and photos :)

Yeah, looks like it but once you start trying you'll see how hard it is.
Nice challenge Simon! :up:
Let me kick off with 290 HT:
http://img.photobucket.com/albums/v620/Z3us/06290HT.jpg
You guys have no idea what a frustrating time i had getting there, i could boot into windows at 330HT!
http://img.photobucket.com/albums/v620/Z3us/1M330HT.jpg
More to come for sure. :)
nm..........
Hmmm Me likey the HT challenge.....
Reminds me of the good old days when FX chips were way way way out of my price range :up:
I added a 17x run. I will try a 10x next. I have ram that does not like real low dividers so we'll see how it goes.
http://3800z24.info/Phenom/965/4.3-3d06-310ht.JPG
http://3800z24.info/Phenom/965/4.2-3d06-250-17x.JPG
I thought its only using the 10x and 17x multi?.........should have used that for the test
oh crap. I used 14 x not 10.. I am dumb.
well, i'll fix that soon.
I hope I included everything on the picture... got a low overall score due to my 4830, but at least htt is @ 345:
edit: sry for the double cpuz window, i forgot to switch to the memory tab..
http://img704.imageshack.us/img704/6264/54992737.png
Nice run beta.:up: What was your memory speed and timings?
thanks theoldtimer, ram was @ 1380 cl7 (1:2), the nb I dont remember, I was half asleep during testing :)
Seems this bios I updated to to get c3 compatability has killed HTT overclocking........with the 0903 I could at least go up to 295mhz.........now with this 1303 The most I can boot from the bios is 210mhz and using AMDOD the most I can get is 250.....251 locks up.
Ive tried changing memory/nb/cpu speeds and voltages to no avail over the past 3 hours.
Ive also tried on Vista and windows 7.
http://i271.photobucket.com/albums/j...1/17multi1.jpg
well here are some of my results so far :up::yepp:
ambient is 70F and this is in my closed case with xig s1283 and scythe ultra kaze @ 3000rpm
in the next few days i will go back at the 17x multi with some actual cold air, i just cant tonight. (edited with some new 17x multi scores)
all done on windows 7 64bit
got runs with 10x multi @ 300htt, 310htt, 320htt, 330htt, 340htt, 345htt (1st pic below), 349, 350, 351htt all crashed within seconds after applying in AOD (some interesting scores as i had to change nb multis and ram dividers etc between some runs)
i think i need to get it a little colder to get 250+htt on 17x multi... i did get 17x multi with 245htt
EDIT: just ran a few more with some cold air using 17x multi - got up to 255htt = 4335mhz CPU w/ 2800mhz NB (new 2nd pic below)
also notice how much the 4870x2 scores went up with more cpu speed :)
http://i70.photobucket.com/albums/i8...on2/345htt.jpg
http://i70.photobucket.com/albums/i8...5htthighnb.jpg
Nice runs man
On a side note...
Using the 10x multi I have to limit my NB to 2500mhz to keep in line with the cpu at 2500mhz and my 250mhz HTT limit
I can boot to windows with the copu at 2ghz and the nb at 2.8ghz and run 3dm06
If I try to raise the HTT to 250 and try to keep the nb around 2700-2900 the system hangs and reboots due to the fact that AMDOD doesnt like nb higher than cpu
Also If I have the cpu at 2ghz and the nb at 2.8ghz and I try to open AOD it will automatically set a higher multi to get the cpu above the NB.
just a couple notes Id like to make people aware of
Ugh....:(
I cannot compete here unless i get a bios that will allow more bus speed.
Definately a bios issue, already flashed back from bios 1003 to 0503 without result.
Wondering what others will get with this crosshair III. 345 busspeed is awesome. :up:
What voltage do you guys set for chipset?
Which is the right bios? :confused:
Thanks man, no need for asking the user, it was in the screenshot. ;)
I was stuck around 255 HTT. Upping the NB (chipset) to 1.2 (+.1v) got me up to 311 HTT stable enough to run 3D06...
Heres the SS @ 311Htt
http://i30.photobucket.com/albums/c3...3_Nomis10x.png
I think Im officially out of this AOD is not working properly.
as an example I can boot to windows at 285HTT Once in aod if I move the slider down even 1 mhz the system will freeze. Im good to 295mhz from the bios but any movement I make in aod causes a hard lock:shrug:
Titan,
This particular part of the test is not about how "good" you look while getting a result. Its just about getting a result at high HT.
Try killing all devices in bios and drop everything down.
Take a break and take another crack at it later.
Try the asus OC utility that came with your board ( if it came with one ) or try an older version of AOD.
Good luck. :up:
