Winchester 90nm and Prime95

[Mentaly]

only because CPUs "suck for overclocking" doesn't make it "bad parts". come on guys, you're just geting ridiculous here

Hi


I agree with you, couldnt have said it better myself....

You added some thermal paste and what - it primed fine?

It did last night

I think you missed a very important reply...
"I'm talking about the ones that aren't priming @ stock. Out of 4 CPUs I had 1 defective one myself. Just from my first hand experience a 25% failure rate isn't exactly steller. "

Of course we arent calling poor overclockers defective, just the ones that wont prime at stock settings.

[dnottis]

Hey guy ! My CPU, Mobo ( chipdate ) are same urs... With Aircool I can Run 300x9 evryday... I think U should use 1.41 Mod BIOS or 1.36Mod ( NF Raid ) to get higher...

Well you got a better overclocking CPU than me then - I cannot run at 2.6Ghz no matter what voltage I give it. I can run 300 x 8.

Hi

I know what you mean, I just had the feeling some of the postings sounded like it was because not all clocked well, I have watercooling on my own chipset, and I must say the little goble of goo didnt look to good on my board either, so I replaced.

I contacted the AMD tech support and requested for RMA. I just want to let you guys know that if you are going to RMA your processor, it will take months. Since AMD do not have any 90nm in stock. AMD offered me a replacement with the 130nm but I decided to wait.

It is time for me to get a new A64. Is the 3200+ good to overclock?

[dnottis]

Did AMD have any thoughts on any of this?
-haha this could get good...
AMD REP "It's Prime95, the program is no good - use OUR stability testing software"

You wouldnt happen to know where to get a copy of the AMD stability testing software as it isnt posted on AMD's website or at least I didnt see it.

LOL, it's was a joke! hehe

ummm

he was being sarcastic...

First things first.. does anybody has a NON-MSI K8N Neo2 board and a CPU that fails @ STOCK SPEEDS?!

[andyOCZ]

Hey guys,

I would say that our "thoery" is pretty well proven. Under stand that my original testing was done on the Gigabyte K8NS Ultra-939, so any doubt about the MSI K8 K8N Neo2 are untrue.

It seems most that have newer 0441 Winnies are ok with Prime95 at stock and also at decent overclocked speeds. Most earlier 0437 won't prime at 200fsb and certainly won't when overclocked. Again this was tested and confirmed on the GB and MSI boards.

The bottom line is that most guys are stable and happy without P95. This argument has been going on for years. If you are happy without Prime95, then I personally have no problem with that.

I appreciate the great responses and testing that you all added.

This screenie shows my 3200+ 90nm 0441 passing P95 blend at 10 x 255mhz running +5% on the CPU, 1.45 CPU VID, 2.5-3-3-10 1t with OCZ 3200 Platinum R2 at 3.0v. The memory doesn't need that much voltage to run 255mhz but the booster was in there and I just left it alone.


I will check back, but this will be the last of my testing for a while. I have allot to do

[andyOCZ]

Read the above post. Yes, a GB K8NS Ultra-939. It was the first board I used for testing.

[IvanAndreevich]

Right, so there goes the $hitty board theory

You shouldn't test blend, cause as you can see, it is was testing small FFTs which doesn't have anything to do with RAM. As I understand, the CPUs fail @ large FFT sizes (in excess of L1+L2). If you want to test quicker, you run Custom with FFT size 2048-4096 and manually lower the amount of ram a bit so there is no swapping happening. IMO this would allow you to stress test the memory controller a LOT faster than Blend mode which also tests the core.

Well, we were not trying to design tests to stress anything in particular, We are not sure that the issue is the memory controller, so it just became a pass or fail situation after we had reports of P95 blend not running.

I like you idea and will give it as try soon. Thanks.

My week37 CPU usually fails between the 2048-4096FFT's. Stock speeds and SPD timings (Some old OCZ PC3500 EL DDR 2x512MB), 2T enabled:

Actually, there were a few people reported to AMD tech support regarding to Prime95. Obviously, they will not make any official statement about it. The software CPU Burn-in is what AMD tech support use for stability testing.

[DevilsRejection]

well now that newegg is dealyed with 3500's whenever they do get them i know i will have atleast week 41 lol

So it seems you are basing that all on this:

Well as I said I picked up a new CPU last night. I found a 3200+ 0441 date code Winnie at Fry's. I pulled the 3500+ 0437 Winnie that was failing P95 blend. I did nothing but swap the CPU and in fact the MSI K8N Neo 2 fired right up into Windows. I ran P95 all night.

See for yourself:

andy, give up the crusade! Look, you found a chip that runs Prime stable, which disproves your theory, but instead of saying, "hmm okay maybe I'm wrong" you make up new conditions? Come on...

[SteveOCZ]

I heard AMD may have pulled their new 0.09nm chips from stores in Europe.....anyone else heard anything?

you work for ocz lol, cant you email AMD?

[p0k]

I spoke with AMD tech support in USA, and they said they have received a few complains from the customers about Prime95 related trouble. Obviously, AMD tech support did not make any official statement regarding to this matter while I was on the phone with them.

Anyway, how are you doing? I saw your post regarding to your accident... I have a Jetta V6 myself and it is a great car. I hope you are getting better. What a terrible accident!!!

Let me out this in a way that we can all understand.

This is no crusade. I am in fact am a huge AMD fan. I work for a company that sells memory. We recently had several RMAs's based on P95 not working at overclocked speeds. Thorough testing by myself and many others has shown that there are issues with P95 and at least week pre-week 41 90nm CPU's.

If a CPU will not run Prime95 at stock speeds it seems logical that it will not run it at 260mhz. We needed to know what was going on and asked for help from our buddies here.

The results form this testing will save my company $$$$, our customers will save time and $$$$ from shipping costs. They are free to use whatever stabilty programs and CPU they like, BUT if their RMA is based on P95 results then we all need to be aware that a problem does between P95 and some CPU's.

I personally do have a perfect 3200+ 90nm week 41 that will run any program I choose for hour on end. Please read the entire thread and follow along to see the purpose and results of all testing.

I suggest that anyone failing Prime95 at overclocked speeds reset their BIOS to default and run the test again for a minimum of 7 hours. If you pass at stock speeds you should go to go, Test away.

Thanks

Ok guys, fair enough, i think that selling the whole system will take much less time and buy something that will run at stock speeds .
Anyways just for your interest, my cpu controller maxes out at 2.46G no matter what i do, i've primed for lots of hours with large fft's without any errors. But even the slightest fsb more than 246 it will fail within couple of minutes.
Before i hooked a northbridge waterblock on at 9x270 (2.43G) i had some stability problems while was running prime... such as monitor was freaking out with no reason and then it was comming back to life, also prime was failing after few minutes.
Now with the waterblock on using artic silver ceramique i run prime for hours just fine at that speed!
I've noticed when i removed the stock northbridge heatsink that there was not sufficient ammount of thermal paste between chip/heatsink. In some way the thermal paste was very sticky which was causing no good contact.

Conclusions are yours...

P.S.: with the waterblock on the northbridge the cpu max speed didn't changed, just stability at high fsb's.

[phobix]

Can anyone confirm if a non Nvidia based chipset with a 90nm 939 has failed prime at stock speeds? This would further reinforce the theory in this thread that the CPU is the culprit.
