The Phenom II List of Overclocks

[jonspd]

I prime above what I'm gonna run 24/7. For instance this is 10 hours prime stable at 202 instead of 200. And chances are if I get 1 EUE in F@H smp I will drop it .5x muilti

I remember the days where it used to be 18-24 hours of prime to insure stability what happen to that

thats a good oc right there

[cbjaust]

I agree with AMDGeeks.net and their definition of a stable overclock:

"Level 3
Certified 'Rock stable overclock'

* CPU-Z validation
* Super PI Mod 1M pic (1.4/1.5)
* 10 Hrs Stressprime pic (Prime95/SP2004)"

As a I side note does anybody know if Orthos picks up all cores of CPUs with more that 2 cores and automatically run 4 threads on them?

9-11 hours?...Easy for someone who runs their cpu at stock for "bios testing" lol.......put a little juice into it..........anyone could run prime at stock settings so whats the deal with that?

Not quite I am referring to my 9850 BE that I sold a while back.


This chip is @Stock because its a DUD and B2 Revision that does not OC

thats cool Did you sell it to get money for the P2?? If so nice move

Dave .......could be that first generation hardware was inadequate Don't know. But I do know that most of the board related issues are from people pushing the HT.................(Thats a Fact).....did you do that? I know myself I have been very mindful of not doing that in any given case because of what I was witnessing happening to others boards..so I avoided it and have primed my machine for 9-11 hrs on numerous occasions same board since day one without issue

C'mon Dave I aint calling anyone out as a noob but this new standard of stability testing is not what I would call stable in which to judge

Bro, I'm not really sure the mobos have gotten that much better, especially concerning the PWM sections of the boards (Asus 79-T being the possible exception)... Most of my chips have been BE's, and I've only used the HTref to tweak my memory and it has never really required much over 220 on that clock (1180 Mem speed)...

When my DKA790 died my HTref was well under 220, I can't say for a fact that your wrong, but I'm really not sure high HT clocks kill boards...

From my experience, high V's kill stuff faster than anything else. When my MSI died I modded the AOD file to allow 1.55 CPUvid, and it popped after only 20 minutes of P95....

I'm not really sure that your assumtion that high HTRef clocks kill boards. I agree with ya the that with BE chips it's really not nescassary and can cause more problems than it's worth, but when OC'ing a locked chip as long as you keep V's under control I'm not sure it is a board killer either.... If I had a PhII 920 I wouldn't hesitate to crank the HTref to 250.

My biggest problem is running Prime95 for hours on end... Most Phenom boards still have weak PWM sections with inadequate cooling. Even the boards with Heatpipe coolers still don't do the job...

Most of the people I've seen kill stuff do it by running really high V's on their IMC/NB volts... My personal limits on these are:

1.55v's on the CPU core (Asus 79-T)
And 1.4v's on the IMC (bench only, everday I keep it under 1.375v)
The IMC is VERY sensitive to high voltage!

All that being said, for me IntelBurnTest will catch errors in 20 minutes that will seem stable even after hours of P95, and I don't have to worry about waking up up with a dead box...

FYI: What this video and you will see what AMD considers as stable overclock for the Phenom II processor.

Gotta say, Some lame excuses about stability in here, If you are scared to run prime because you believe your system might melt then its time to bring it back a notch. You cannot redefine stability because you don't want to melt a weak platform.

[Jaivan]

How about other criteria for "stability" for crunchers.
I run BOINC 24/7 on my rig and don't really want to use prime to take up 2hrs+ of precious crunching time and I think that many other crunchers feels the same way.
So what if I show that my system is "stable" by posting the up time from windows task manager showing an up time of like 3 days or something?
From my experience it seems that BOINC can be a valid stability test it just needs to run a lot longer than p95 since it doesn't stress the cpu as much as p95.
Also as a side note I find that gaming and crunching at the same time is the best test for stability.

[DYM]

Agree about BOINC + gaming/other work qualifying as a good stability test. Used to be my test back in the day when I ran my Athlon 500@950, and still is. Running Prime for 8+x hours is not for me.

My system is stable and I dont run prime..........I dont think theres anyone who can make me believe that its not.........the cpu and memory are not the only components in a system that get stressed to the limit running prime. Other components that route voltages on the mobo may be a weak link and heat is the killer.

Like the video above they ran Crysis at 5.6ghz stable.....I didnt see anyone yell out "hey thats not stable......you have to run prime95 for 8-12 hours"

So above you got AMDgeeks.net say you need to prime for your system to be stable then you got AMD saying a cpu is stable basically as long as it runs a game without shutting down. Obviously we have 2 different sides and it can go back and forth all day long. If you want to prime go prime If you dont want to prime then dont prime. Just dont try to convince the opposite side that you are right.

[Oldguy932]

2 hours of prime is final. I only shortened the time so that more people could find time to run it. Missing 2 hours of crunching is not the end of the world, you could run both at the same time as long as you make sure each one stays out of each other's way with memory.

I don't know how high ht speeds kill a system, my m3a32-mvp did 2700mhz with it on my first 9850. I'll be able to try again with my other one as soon as all the parts for my new system come in this week.

[KELL5]

prime is for perfectionists and folders. No-one in this world needs their cpu to NEVER ERROR. If they do, then they screwed cos they all do, even the PRIME STABLE machines. The only difference is they can fix their errors, while a machine that isn't prime stable is making too many errors to correct them all.

I'd like a prime guru to show me a cpu that NEVER makes ANY errors

Fritz chess bench on all cores, hyper-pi 32m on four cores to 32m then ice storm fighters (intel users) for 30mins and a machine is perfectly stable for most users.

[[XC] gomeler]

If you guys are willing to accept results without the Prime requirement then I can share a slew of results when CES starts. There is no way in hell I'm waiting even 2 hours for Prime to run, LN2 costs too much

[Oldguy932]

That's why there are separate lists. I'm going to be working on two separate list in this thread. One for people that do stability runs of prime, others that don't. I can't believe the fact that I wanted to go by the old standard of 8 hours that we have 3 pages of nonsense.

@jonspd - Could you post the information about your cpu? I just need your stepping and get a picture of prime when you can. I just started the tables in excel so your data is the guinea pig since you were the first post to have your overclock in it.

Edit: The list of just jonspd is linked in a word document right now. I will convert it over to an image file after I get more results. It will be in the same format as the word document, just as a picture file so you don't have to download it.

But if your cpu produces errors and is crapping WUs, it make other people wait longer for there validation.

If a rig can run several hours prime/linx/occt it can run everything. Cause this tools put a unusual high stress on the cpu, and if the can run that stable, they can run everything stable.

But anyone whos demanding to run prime on extreme oc is out of there mind.

Who runs LN2 cooling for 24/7 anyway.

If the system is not cabable to run 24/7 with that specific cooling it makes no sense to test it if its prime stable or not.

Yea but who has there main rig under LN2? thats strictly a benching rig for possible highest.......not encoding video.


@OLDGUY............I find OCCT 1hr High Priority CPU Test to be the thing that's hardest to Pass........Not Prime95

hmmmmmmm sounds good.

[Oldguy932]

If everyone agrees on OCCT for one hour then I'm fine with that. Just as long as everyone agrees on some form of stability.

I think it's a moot point why AMD mobos are so cheap; I mean how far back does one need to move back the goal post? With all the talk in here you'd think P95 is the return of godzilla.

Just run the standard 8hr stability standard for pete's sake. I'm very interested, but won't buy PII until I actually see many chips doing 3.8 - 4.0 Ghz air stable.

None of the 790gx mobos cost more $170 and they all overclock well. I won't buy PII until the prices drop. As to how well they clock, well i think we have enough info to have a pretty good idea. I bet even the worst chips get to at least 3.4

[roofsniper]

zucker is only posting because hes trying to find a way to bash amd once again and this thread is a little hard to do it in. please don't quote him. and even though he says he might buy phenom II we all know its a load of . he obviously has never ran or even seen a 790fx so he knows nothing about it. but he can call everyone ignorant tho. im still baffled why he even posts.

[rk7p5]

It's just an exciting time to be an overclocking enthusiast. So many choices and such great prices I'll never understand all the negativity

[BertM]

my carefull approach on benching new tech so long is based also on the failing 45nm intel chips we see here at xs.
it is unknown how long amd can run on high oc/voltage, i let the hardcore xs amd guys find that out.

[rypt]

Indeed. What's the point if clocking the chip so high if any use of that power will cause it to kill half your computer.
Next people will say "it posts, so it's stable".

Define "high" voltage, one would expect that the chips are fine running up to the max voltage as stated by AMD. Afterall, the Intel 45nm chips have been fine as long as they were not pushed beyond 1.4/1.45v (which was the max voltage as per Intel specs I believe).


My personal view is that Intel BurnTest should be used, it "kills" things far quicker than Prime can.
