Well, I keep getting these unrecoverable hardware error bluescreens from prime that don't make sense. I've never gotten errors like that before so I don't know if it actually is the cpu or if something else is screwed up. I wish the temp diode actually read below 0 because it just says 0 for me, but the bios reading is -10C at the stock speed of everything and stock voltage.
And yeah it is pretty funny that you got the same stepping when you live in ohio with me.
I bought it off newegg lolQuote:

I got mine from the local microcenter.
Dumo, could you post your stepping and the motherboard you're using?
And for people to post later on, please remember to post everything to make it easier on me when I add you to the list.
Edit: I think I may have found the problem with high multipliers. When I booted up with the 18.5x one AOD would get completely screwed up readings of me being at 4.5ghz instead of the 3.7ghz I was actually at. Hopefully setting the multi through AOD won't do the same thing or it'll be time to complain for a new bios.
Old guy did you pack the cpu socket with dielectic? I had that problem the first time I ever used phase, It was condesation jumping across pins because I didn't pack the heck out of the socket with grease.
Heres with Giga 790GP-DS4H..

Guess demonkevy666 has found a good batch from what it seems so far 2 3.8's stock volts is very impressive.
Let's hope they all end up being that good soon.
Sweet dumo batch # 59 lol, I wonder how you got that :D although i'm a little disapointed I would have thought you would have opted for one at least under 50 :shakes:
I want to see how good that board is...Quote:

@ chew - I might try that eventually, but it never gave me a problem before. I keep the underside heater on with a little power to make sure it evaporates or something like that.
Man... screensaver just started and scared me :banana::banana::banana::banana:less...
Ditch the heaters, and get some eraser and pack it in the backplate and front plate ,around the socket and all around the head :up: and pack it with grease trust me I lost the MMC once without it, chip became a 754 single channel...........It's fine without for some testing but 24/7 is a No No.Quote:

I am going to keep experimenting with 3.9 for now. I need some more voltage tweaking to get it stable.
I guess I'll be doing that soon :rolleyes:.
3.6ghz is no go on stock volts, trying 3.5ghz now.
I'm on air, vista 64 bit here.
been benching with generic cpu bench. simple yet it puts full load on the cores quickly and load @ 3.5ghz stock volts.
idle 36C load 48C.
old 9850 idle 3.0ghz at 1.475 volts 44C load 57C.
I'm just doing small fft's atm. I want to find a base point before adding voltage into the game.
Edit: I might also need to do some windows updates. The computer isn't connected to the internet so it doesn't have any updates other than the drivers I ported over.
3.6 is working now oddly enough. Stock volts and all. So now I get to complain to Asus that I want a new bios so things stop screwing up...
Here is another one about to be put under testing..
http://img166.imageshack.us/img166/8991/img0323tm5.jpg
Got it from the same shop as Dumo
I see AMD is still using the T stamp on the PCB of the chip, anyone getting pcb's stamped N?
Good to see more chips getting tested. Do you guys like being able to download it in a word document or is it about time for me to convert it to a gif so it can be viewed on the page?
Just curious did you try the 2.1.5 version of AOD?Quote:

The more I think about it the more I think my 19x multiplier thing is a motherboard clock generator multiplier max. I'll try bumping HTT.
My board doesn't like anything above 17.5x so far. I'm testing 4ghz with 267x15 because it likes it the most this way so far. Quite a bit more voltage than expected though, I'm at 1.5v set in bios, cpu-z is reading 1.52v right now. I think I might be putting the grease in the socket if it doesn't work with this much voltage, I probably will no matter what though. It seems I got a dud of a cpu, won't a new one till AM3 though.
I got my cpu this morning and started with some simple tweaking, I'll use these settings as my base for finetuning. Idle temps were around 30 degrees Celcius and the highest load temp I've seen was 52 degrees, ambient temp is 22 Degrees.
Okay, here we go:

Old guy,
Your results don't surprise me and I don't think your chip is a dud. I've yet to see uber clocks on that asus board "brick:banana::banana::banana::banana:house" PWM or not.
I have seen the board take a dump when trying to acchieve uber clocks however.
Not saying that the board is junk yet but the trend I have seen is leaning that direction atm.
That cap next to the socket isn't helping people looking for subzero usage out at all either......
Whats your last 5 digits by the way bottom row without me scanning through the thread?
I'll have to check that when I put grease in the socket, I've never paid attention to more than just the stepping so I don't write it down or anything. It finally seems stable with 1.525v set for 4ghz. I bet my gx board would be better except that it maxes out at 1.25vid. With the 1.5v I can set with this board I would have had a good chance at the WR for the regular 9600.
Do you know an easy way to tell when you've reached the limit of phase cooling before you hit positive temps with the cpu? The evap head is sitting at about -38.5C, the bios reads at 7C, and the cpu still reads at 0C.
the 79t has 3 of the 5 top validations - 6.0, 6.1, 6.2
Sure thats not the deluxe ;) a board not released yet.......FYI just because its validated does not mean its the highest.......gigabyte did up to 6.3 at the events, I saw 6.1 myself.....Quote:
Originally Posted by crazydiamond

Is one of those the new board ( unreleased )? there model #rs can be really confusing...Quote:

Well, 4.1 (256x16) looks like it should be stable with 1.5625 set. Made it 15 minutes in with 1.55 and it restarted. Not sure how much farther its really feasible to go, at this point I'm going to be happy to hit 4.5 stable, 4.3 looks to be achievable at least. I just saved a validation of 4.1 so I at least have that for you guys. Won't be able to upload it till later though.
Alright folks to some this is important info as I believe I have the only nvidia system using a Phenom II
Just got the chip in on my MSI 750a, boots up just fine but just a warning the dual-core center diagnostic sidebar for vista will BSOD your PC with this chip, just fyi.
Chip's stepping is as follows:
CACVC AC 0850 BPDW
So far:
4ghz BSOD on startup @ 1.52v
3.8ghz to windows @ 1.52v (STILL TESTING)
That board looks nice but the power/reset buttons on it make me worry about the price. Also bothered by the limited side sata ports.
Looks like it may not have alot of usb ports on the back either.
Can't believe they didn't raise hypertransport specs.
We should have a discussion thread for that.
Back on topic lets see some high nb/hypertransport clocks with 3.6+ core clock on air.
Oh man running into alot of issues here. Voltage past 1.5 doesnt seem to get it bootable into the upper 3.8 ~ 3.9 range. Given that I have an MSI board I believe im running into power issues so I decided to start off nice and low.
3.6ghz @ 1.45 seems to be ok so far, I hope I get more out of it than this but we shall see.

Alright guys, here's my validation for 4.1ghz which is currently priming.
http://valid.canardpc.com/show_oc.php?id=480946
Can't wait to take it even farther...
Ok, good, I almost went into nerd rage mode when I plugged my shiny new chip in and got crazy readings from AOD. Not only does it read my clocks wrong, it reads my HT and mem speed wrong as well. CPU-Z reads perfectly according to what I think it should, although I don't know if the 1Ghz HT link is normal? I'm kinda new here at Phenom OC'ing.Quote:

Then again, DFI, Abit (uGuru), Asus (AI Tune), Gigabyte(Eyastune) have become rather OK for the casual "clocker". :D

Also there's something a bit weird about volts with this cpu. When doing prime95 i was watching HWmonitor for temps and i noticed my volts spike down for like .5 seconds when under load. Watchin cpu-z when doing prime95, they go form 1.536>1.52v>1.536. Question I have has anyone else noticed this? I can say that's never happened on this board with my BE-2400 x2, 5800+ x2 BE, and 7750 x2.
Anyways here is my stable OC. (volts 1.52-1.536?) http://valid.canardpc.com/show_oc.php?id=481022
Will prime it tomorrow after I try 14.5 x 265 to reach 3842 , 265 x 9 NB 265 x 8/9 HT.
havent seen any DFI boards yet. *EDIT* just posted right before me with the board i was looking at getting. Would like to see some AIR results from that board with 2x2gb ram.

@ Sgt.McRuff - I need a screen of Prime95 or OCCT to put it in the stable list
@ iandh - I just need your stepping if you have it handy. Your stock voltage is actually low, its supposed to be 1.35v unless you just got a really good chip or something. I think you may need an upgraded bios before your troubles are over.
I just wanted to say I/ we appreciate you doing this. :yepp::up:Quote:

Anyway, I have a Prime95 stable result for you. I ran it overnight at a conservative set of settings to establish a baseline:
8h54m (user canceled)
3610MHz (225 x 16)
1.45V vCore
NB 2025MHz
Load temps were about 48C. You should really, really, really track load temps in your chart btw. If people with lower temps are doing the good results, that's really significant information.
load temps are nice but they can vary from cooler to cooler, from different ambients, etc.

on my way xD
i have to set up xp32bit for ocing.. vista 64bit really is holding me back..
Oldguy932 I will post stepping when new hardware arrives...
Well, this doesn't make sense. I just insulated the socket with paste. Before the core temp would never move from 0C, but now its sitting at 2-3C. I'm thinking that the paste needs to set on top of the cpu, or I didn't get enough on the cpu itself. Socket temp according to speedfan is the same as it was. Maybe it needs to cure or something, I don't know, but I don't like it.
I'm also retrying 256x16 @ 1.575v right now. Core 2 gave me an error after 1:04 so I'm hoping that it was because I hadn't insulated.
@chew - The number was 154, so its not a cherry chip, but its also not like one of my 3xx ones that I have sitting around of other cpu's. Should be pretty good.
2hrs prime stable.. is that enough for the list?
http://www.abload.de/thumb/primev199.jpg
stepping is in my sig.
cpu is watercooled.
windows vista ultimate x64
unfortunately core 2 errored at 2hrs6mins. will try this with a little more vcore.
I think you might want to try with a little less vcore. Unless you got one that was like on the edge of the wafer, it should take 1.4v at most for that. Also, don't try for stability with anything above the 17.5x multi on that board, it just doesn't work yet.
Updating in the next few minutes.
Edit: Nevermind that, I forgot you were running x64.
iīve got no probs with the 18multi so far. too bad that my ram doesnīt do more than 1066mhz, so ocīing thru htt isnīt a good option, unless i let my ram run under 1000mhz.Quote:

Clearly I'm not grasping all these new K10 variables right. I thought I'd hit a limit if I put everything else down and upped the bus speed. I reached 300 with no issues. :(
http://halk.pwp.blueyonder.co.uk/300bus.gif
Impressive bus speed that's for sure. Tbh it's a lot like the base clock on i7 chips, it doesn't really do much to help peformance so most people keep it below 250.Quote:

For the record Im having issues with multipliers as well except for me its anything above 16x, oddly enough it feels like the lower I put the multiplier the more stable the chip is for some odd reason...as 15x versus 16.5x seems stable with .5v less at the same speed which is weird.Quote:
Originally Posted by Oldguy932

EDIT: No go, sadly my ram isnt going to cooperate with this little experiment. Either I drop the multi of it down and then my board wont post 300+ or I go out of spec of my ram and it BSODs. :(
This K10 architecture is new to me and it's a long time since I overclocked anyway, so I'm stabbing in the dark. I'm trying to follow old methods, which is to turn all the knobs down and then turn one knob up to find the max. I do not think the 300 is realistic when I turn the other knobs back up though, not from the other clocks I've seen. But what do I know :)
anyone know a good bios for the K9A2 plat, im stuck with 10x NB multi on the 1.6 and i dont know of any flasher besides their Live update one, which only gives me the 1.6
I got 267 with the 15x multi. Not sure if higher was a problem because of my ram though. My board is just being finicky with any real settings I try with it. Its finally starting to get colder though, a few degrees here according to the socket temp, but that's all I have to go by other than evap temp which doesn't say much.
Yes, and that's the whole point. CPU temps are CPU temps regardless of the cooler. If people with better coolers and/or lower ambients are clocking better because their core temperature is lower, that's significant. From my experiments, temps seem almost more important than voltage on Deneb.Quote:

800MHz RAM Setting = 1:2
So for example, DDR2-800 memory with an HTT of 250MHz and a RAM setting being at DDR2-667 in the BIOS will yield 399MHz (which is the same as stock spec). :) Remember to drop your RAM multipliers, people!
I don't really have much room left in the table to add temps in, plus I then I'd have to go and have everyone that already posted post temps as well. People on phase like me also don't technically have temps until we shove 1.6v or so through the chip.
Not a big deal or anything, but could you try saving the database as an html file? Seems I have a different batch than everyone else. I've never yet owned a great chip (some good ones), so maybe this is my turn! CACVC AC 0850DPCW
Mine arrived yesterday, and looks strong, not up there with the best but good enuff for me! Seen some nice ocīs in this thread! Phenom II is soo much fun!
Oldguy932 screen for your database!
http://i30.photobucket.com/albums/c3...ic/FirstOC.jpg
Good place to ask this Id guess, but do you overclock northbridge/ hypertransport seperatelly from the core?
Halk thats not what I meant unfortunatelly, I'll trying to make this more clear this time.
Umm, I meant does it make it harder to clock up the northbridge/ hypertransport the higher you clock the core? Does it make it need more voltage or anything?
Because anyone that has a high core clock so far doesn't have much for northbridge/ hypertransport.
Yeah, the core multiplier has no effect on the rest of the system. So multiplier clocks work well. It's not the best overclock of course, the best one would be the lowest multiplier for the highest speed I guess.
Another one for you Oldguy932 :)
