Chip does 3.6ghz on Air I said 3.7ghz on Water more than likely

Give me $110.00 and its yours! I keep it @3.5ghz @1.4vcore (Stock Voltage) so I have never really opened it up nor run excessive voltage to it either was gonna go water cooling and crank it up when my CoolIt came back from RMA but need to start looking into Bios on the Phenom level sooooooooooooo let me know.

[justapost]

You need PLCC Extraction Tool and there is a risk that when removing the Bios Chip or Replacing it can drop on the Motherboard and short it out or Damage the chip or both. So yes there is Risk involved not to mention ESD damage as well it should be done in a rea that is a ESD Work area or at the very least in the Kitchen or Room that does not have Carpeting and you should at a minimum have a ESD Wristband and don't go walking back and forth on Carpet and build up static electricity during the procedure matter of fact less walking or moving you do the better and make sure you have everything you need prior to doing this too.

Thank you, found that tool for 5€

Also I found two old p4s800--mx mobos with bios chips of the same size. I can try it with those first.
Floor and table are made out of wood will make sure i'm grounded.

Any results with your 9600BE?

[Rammsteiner]

Brother Esau,

My system was 8hours+ stable Prime95 before 1/30 BIOS. When 1/30 was released I simply flashed the BIOS and didnt look at it again. After the flash untill 22th of February (when I went on holiday) I didnt really play a lot. I tried out UT3 a little. But that game crashed, but I never played UT3 before the flash. Also i went on the internet when it happened and more people had those problems so I couldn't/can't tell whether the crashes came from UT3 or the BIOS.

Also I tried to get the RAM upto 586Mhz which failed, but again, I dont know whether this was due to bad BIOS or hardware.

After I came back from vacation I started to play EvE-Online again as I took a little 2~3 month brake for my new PC. Then I started to notice I crashed now and then as EvE-Online never crashed. Though I didnt know about the BIOS problems.

As internet wasn't working last friday I investigated everything a little and it seemed like the whole system wasnt stable at all. Playing around a little sometimes caused insta BSOD or longer stability. But in the end Prime95 simply gave an error and/or caused a BSOD. But if Prime95 runs 4 hours and 54 minutes finally it gave an error again at 3.5Ghz instead of 3.51Ghz. Tried old Voltage settings and higher, it didnt matter.

Also tried to put RAM on 667 divider and let the CPU run at the old settings, still a BSOD in Prime95 while running Small FFT's which hardly uses any RAM. But the CPU was for 110% stable at the old settings, both on the DFI as on the Gigabyte DQ6.

So to go short, I know my system was stable before and I never really stress tested with 1/30. But as I look now and whatever I change, it doesnt matter sooner or later there will be an error and/or BSOD. I do know that the BIOS I used before 1/30 was 11/22.

I mean, Ive D9's and I know about the electron migration but running Small FFT's and still BSOD'ing at 100% stable CPU settings makes me doubting it's due to the RAM. Both CPU and RAM tests in Prime95 seem to crash, which doesnt make any sense. Lowering the HTT by 1Mhz gave a lot of more stability, from 17 minutes to 54 minutes. And as I said before, at some point I even got 4 hours and 54 minutes before error or BSOD. But I KNOW my CPU can do 3.52Ghz 100% stable, so could my RAM do the things before although the electron migration part could have been an issue too, at least, if it was only the RAM causing BSOD's (IMO then), but it's not only the RAM.

So Dr Brother , what do you think? It doesnt really makes sense it's hardware related.

[Brother Esau]

Seems to be allot of this going on lately no doubt, coincidence ??? I don't think so! My best advice on this to everybody is If you have tested stable on Prime95 Stable for 8hrs on what ever Bios it was with Proven Stable settings in that Particular Bios that you know for sure I would suggest any of you that may think this situation is affecting you please Flash Back to the Previous Bios Release that is Proven STABLE through extensive testing before you start doing the Hokey - Pokey with the Last Resort Procedure I wrote 2-3 Pages back Please just use you're common sense and go back to what worked for sure for you with you're Particular Hardware set up and Diagnose from that point onward

[Rammsteiner]

*sigh*

Did your BIOS flash thing from 3 pages back... Damn, more work than you would think at first.

Anyway, Ill start Prime95 in a sec so, lets hope it's all good now

[Oese]

*holding both thumbs..*

[Rammsteiner]

Mkay then,

Prime95 hold a lot longer this time. Though it BSOD'd again and I linked that right to the RAM. Downloaded Memtest (just in Windows though) and tried a few timings a bit more loose as I always had 'problems' with those specific timings (they were new to me and 'intoduced' with newer Memset beta).

Anyway, after that I ran too instances of Memtest each testing 750MB and after 900% coverage still no errors. Will try to get the timings a little bit better, but at least I dont have the annoying crap anymore of past few days.

[3oh6]

Hi 3oh6 have you been able to run the 5000be with the ocz 4gb kit lately?
I'm really interested, am trying another run with trfc upped. Maby that will remove the 308 htt lock

sorry mate, testing on the Phenoms went longer than it should have...waaaaay longer. needless to say, i am done (god i hope i am anyway) and just tossed the 5000+ BE in there. it doesn't look like i am having any of the issues you are with the HTT. perhaps you are just trying to run the memory too high or something else. here is a quick screen i did for ya. no time for real stability testing but it seems like everything is fine for me with this kit and this board. 11/22/07 BIOS BTW...HTH

DFI has my bad M2RS now, hoping they have a quick turnaround and I have my replacement by this coming weekend.

By the way, I checked the stepping on my phenom 9600BE, it is CAAWB AA 0747MPMW - any info on that as to whether it appears to be a decent clocker or not, or is it too early to really say yet what steppings are good?

[Brother Esau]

Sparky none of them are decent clockers I really do not think its even worth the strain on the CPU to attempt such on a full time Basis and I think the Key with these Chips would be to get the in tandem with 2X2GB RAM Kit @1066MHZ and call it a day!

[Sparky]

seriously?

If I can't OC then that's a waste of money

should have gone darkside then if I want to OC?

[Rammsteiner]

Nah, AMD is more fun to OC. For pure 3DMark06's, Intel is still better at the moment yes. Still I stand my point, AMD is more fun to tweak.

Anyway, to get back on my BSOD crap... It's still there. Most stupid part is, my memory is very stable with my timings. I ran four instances of Memtest in Windows, each 750MB for a few hours without any problems (all of them had 550% Coverage and 0 errors).

I start Prime95 and within no time BSOD. Tried to run Prime95 in safe mode, same story.

I put the multiplier from 14 to 12 and leave the rest alone, Prime95 runs without problems (only tested for 2 hours though). But there's no way my CPU would be crapping out, it never ran beyond 50C, nor did I put up a lot of Voltage on it. And, it's been stable before

I just searched for the BSOD and lots of people have those BSOD's related to software issues

Here's the two BSOD's I just got at a restart:
BCCode : 1e BCP1 : FFFFFFFFC0000005 BCP2 : FFFFFADF8F80C202
BCP3 : 0000000000000000 BCP4 : FFFFFFFFFFFFFFFF OSVer : 5_2_3790
SP : 2_0 Product : 256_1

BCCode : d1 BCP1 : FFFFFADB90BD00D2 BCP2 : 0000000000000002
BCP3 : 0000000000000008 BCP4 : FFFFFADB90BD00D2 OSVer : 5_2_3790
SP : 2_0 Product : 256_1

Well, Im out of clues. As far as I know I didnt install any new drivers since a long time. Last one was 8.1 at 24th of January. Also, I just remembered that inbetween 30th of January and 22th of February I tried to OC my RAM good, I had to repair XP64 very often due to corruption, maybe that might be it? Anyone knos what those BSOD's are for?

[Sparky]

Nah, AMD is more fun to OC. For pure 3DMark06's, Intel is still better at the moment yes. Still I stand my point, AMD is more fun to tweak.

I don't care much about super pi or 3dmark benchmark scores, I know intel is better at that. super pi has always been intel's ground anyway. But if phenom really doesn't OC, well.... :/ I was hoping for close to 2.8GHz, that way I'd be at the same speed as my old opty 165 just with 2 more cores basically.

Well hopefully when the board gets back from RMA (this weekend, please!!!) I'll be able to OC this thing. Would be nice.

As to the rest of your post.... I got lost in there somewhere, my head exploded The BSOD codes get me confused.

[Brother Esau]

Sorry Mate but unless you get exceptionally lucky (which most don't) reality is that maybe 200mhz above rated clock frequency for 24/7 use is being very realistic from what I can obtain from following this processor from Public Launch and what I see from users on this forum that give it their best go its just a No Go as I see it being realistic that is and truthful

[Sparky]

............

tempted again to sell this 9600BE and mobo and get something that overclocks... or maybe just sell the CPU and go back dual core 6400+ or something and hit 3.5GHz if possible...

[Brother Esau]

Don't get me wrong bro Rules are meant to be broken and nothing is written in stone that you will not be able to get what you want out of it but the M2RS has 4 Phase Analog PWM and don't know if thats gonna handicap you from the front line or not

[Sparky]

Well I've decided I'm going to give it a go anyway and hope for the best. Who knows, maybe I'll have a magic setup, for once! lol..

[aGeoM]

Hi

I was one of the lucky guys to have one 9500 @ 11x250(9xNB;9xHTT) as "default" and 11x255(9xNB;9xHTT) for gaming/benching/24-7 use, with MSI-K9A2 and ASUS-M3A32-DLX/M2N32-DLX untill I got the DFI-790FX, this board, with the same system/settings can't get over 11x240 stable.

Allready tested B07,B22,B30,C06,C21,103,130,212,307,312 bioses released also crossflashed the last Sapphire bios, think is the same as DFI C06, none was able to do 11x250(9xNB;9xHTT), no matter Volt, Mem timings or whatever... it can go over HT250-260 if I lower NB/HTT multi to 8, but not stable (random lockup), don't know what else can I do, or what cud it be, Bios or this particular board limit.
Any one? Oliverda you got a nice 11x279 OC (congrat ) with lower HTT multi, can you try for me the 11x255(9xNB;9xHTT) setting, just to cut the bios variable? Thanks.

@KTE

I didn't forget to post some DFI results, but as you can see I can't replicate the same settings as before; tested a 3-way 3870 CF, fresh Vista x64 install, updates, Cat 8.3 drivers 3GPU CF active,etc... 3DMark06 results lower then just one 3870 , had no time the debug, since 1 GFX wasn't mine, but isn't all bad news, I can hotflash the bios now.

[aGeoM]

Well I've decided I'm going to give it a go anyway and hope for the best. Who knows, maybe I'll have a magic setup, for once! lol..

That's the spirit!

[Rammsteiner]

Errr,

How likely is it a CPU doesnt like a certain multilier (anymore)? Been browsing the web, playing music in WinAmp and running Prime95 for 1.5 hours now by just changing from 14x251 to 16x219. RAM is running slower though but I tested that before and it was ok.

Ive no clue what the hell is going on here lol

Yesterday I tested 12x251 with RAM at usual settings and ran 4x Memtest and they covered like 550% each without errors.

If it's 'just' that my 14x multi isn't liked anymore, Im still not very happy. 14x was actually the only most usefull multiplier I could use. I can run a divider of course but that will mean I need to get MAL from 4ns to 7~8ns and gives quite a performance drop.

Is there a way to explain all this anyway? I think this is quite strange. And what might be the cause?

[Brother Esau]

Sometomes that happens with AMD CPU's I had a Opteron 175 default 11 Multi and it overclocked and responded better to X10 Multi

[KTE]

Someone here or elsewhere posted a +15k 9800GX2 2k6 score and 44xx CPU score with a 2.9xG Phenom and 2.3xG NB/HT.
For Phenom, that CPU score is pretty damn good. I'm starting to see a trend here... ATI cards are "eating" the CPU score more than nV cards on this platform.

Hey 3oh6, did you really require that high vCore for that setting? By my experience, it's very high, I only required 1.3V to get to 3.35/6G stable with the stock HSF using two of them CPUs.
Also, how accurate is the DRAM voltage given there? If true, looks very good.

By the way, I checked the stepping on my phenom 9600BE, it is CAAWB AA 0747MPMW - any info on that as to whether it appears to be a decent clocker or not, or is it too early to really say yet what steppings are good?

Unfortunately, its not a stepping issue anymore, more luck based. I tried this by having two 9600 both of the same week and batch and both were different oc'ers, one didn't make it above 2.55G screeny and above 2.5G stable and the other hit 3G screenies and 2.8G stable with 1.3V, stock HSF. TRUE on them didn't help nor did a little subzero. That batch I've also had on one and it reached max 2.68G stable, but that doesn't prove anything about yours.
High speed bin yield issues show up like this exactly, large oc variation between same wafer cut dies, as we see with Phenom. Hence why no 3G/2.8G/2.7G officially planned Phenom yet and late 2.6G.

should have gone darkside then if I want to OC?

They oc far better, yep, there is no doubt about that. But the Q6600 G0 is the key on the Intel side IMHO. If you've seen what mine benches on air, then it outdoes Penryn Yorkfields by a good margin apart from the 4-4.5x priced QX9650/QX9770.

I was hoping for close to 2.8GHz, that way I'd be at the same speed as my old opty 165 just with 2 more cores basically.

I would say you can expect this, from what we've seen so far, by only the top 30% or so, but I would say, a realistic aim with Phenoms is 2.65G stable, ~60% chance. Looks like in-between the average, the poor and the good to me, as 2.6G is fairly average ignoring Vista 64b users.
I've owned 6 Phenoms now; 4 have benched 2.95-2.7G, 3 stable plus 2.7G, 2 stable plus 2.65G and 1 stable only at 2.5G. My new 9600BE I've sold this week, might pick up another this week (not looking forward to opening the box) and just lost picking up a 0739 from my uncle 2days ago, damn, really wanted to test it. It was supposed to be the guaranteed high clocking early batch which some early reviewers were getting, i.e. Kyle.

Sorry Mate but unless you get exceptionally lucky (which most don't) reality is that maybe 200mhz above rated clock frequency for 24/7 use is being very realistic ....

Camon Camp, you've been reading the Vista threads too much and ignoring mine!
No messing, honestly, if your sample can't get even 2.6G stable, then it really is bad luck and you need to get someone else to touch the CPU first off the shelf because you're obviously extremely jinxed.

What's the max you've hit fully stable with Phenom yet (you'll need a week for this at least)?
Thought of trying a different board?

@KTE

I didn't forget to post some DFI results, but as you can see I can't replicate the same settings as before; tested a 3-way 3870 CF, fresh Vista x64 install, updates, Cat 8.3 drivers 3GPU CF active,etc... 3DMark06 results lower then just one 3870 , had no time the debug, since 1 GFX wasn't mine, but isn't all bad news, I can hotflash the bios now.

Great, yeah, you have one of the better Phenoms around. What was max HT on the DFI with low NB/CPU Multi?

I wonder whats happening with the 3GPU setup and the lower oc

Been browsing the web, playing music in WinAmp and running Prime95 for 1.5 hours now by just changing from 14x251 to 16x219.

If you test P95, a cheat people use is to carry on doing other tasks while it runs in the background.
As I stated when I first got a 9500, the way to test P95 is to leave the window as active, in-focus, or Windows prioritizes for the Window in focus, and so the results you're getting is not the actual stress test, so you later end up getting instability out of the blue, but it really was nothing but what you would've caught if stress tested right.

If it's 'just' that my 14x multi isn't liked anymore, Im still not very happy.

Could easily be, my 5000+ didn't like the 16x multi.

Any Minidumps?

[Rammsteiner]

Yeah, Im trying to find out how the hell the Debugger things work lol. It's asking for symbol stuff.

But I do have minidumps yeah.

I looked around by looking in the event stuff, might be indeed a software issue although then I dont understand why exactly lower CPU core gives a longer stability.

And I didnt know running P95 in background was a 'cheat'. Good to know for next time then.

The crashes I have vary from a BSOD to grey and white lines vertically across the screen while everything freezes. No hard reboots or anything like that. I might install Windows freshly onto the other HDD and only install latest drivers + Prime95 and see what that does. But will have to do that at a later time.

But I cant make anything out of this, CPU dieing doesnt make any sense at all, but the memory seems to be fine. Also I just remembered a few things I did before I really noticed the crashes. I installed stuff as AOD and some other apps to check if they could read CPU ODT, CPU NB Voltage etc. Also I tried to OC my memory die-hard and had to repair Windows quite often.

So I dont think it's the CPU dieing although the PC is crashing faster when the CPU is clocked higher. Also the crashes in normal use are very random (and also as I said very from the lines to BSOD). Sometimes only when browsing the internet and playing WinAmp, othertimes while gaming etc. Although I ddint have a BSOD just idle-ing really, but I dont idle a very lot so.
