Winchester 90nm and Prime95

I think we need to sticky this thread.

I think that we've to send the link directly to AMD to see what's going on :D ;)

OK you impatient types. ;)

I had not luck at 9 x 270mhz so I gave up on that. I know this memory will do it but I decided to see what the CPU wil do. Only tried at 1t.

9 x 260htt seems to prime blend fine. Of course only overnight will tell.

I am working on 260mhz x 10 to see if 2600mhz will run. I am upping the voltage slowly to see what happens. So far P95 burps at 3-5 min. Nope 2600mhz is a bust.

Hmm just had something strange happen. Running the 1.41b1 BIOS I just set the CPU volts to 13%, 15%, etc and when I rebbot it defaults back to auto or 1.42v. Anyone else find that? Volts seem to be best at about 1.53 anyway, so maybe it's a 90nm limitation in the BIOS.

Well the latest is 10x 257 and it seems to be priming along. I'll let you know if it's stable after a while.

Yeah mine won't do 260 x 10 regardless of voltage - it will post but isn't stable.

The beta 1.4 only goes up to 10% additional. There are modded ones floating around that allow 1.4 to go 13%, 15% but it's just cosmetic, it doesn't actually work. The only bios that allows more than 1.55 +10% is the 1.3b6. You may be running one of the modded ones, I shy away from those.

Nothing wrong with that - most I can do is about 2.520, even that isn't 100% prime stable. What voltage are you using in bios to get that?

My guess is that a high fsb on the memory, on the winnies often fails b4 the max CPU score is reached.
I get a idle temp(MBM 5) on the CPU of 34C with 250x10, and a idle temp of 41C with 278x9, with ram 1:1.
also the CPU need a notch more Vcore on the 278x9 setting (1,5V).
running with a divider on the memory reduces the temps on the 278x9 setting.

the cpu is prime stable @ 260x10 1,52V (divider on ram) only tried Large FFT, (user stopped after 8hours)

Rather than starting a new thread, my question is a result of prime not passing and forget about prime for a sec, coz when it doesnt pass my comp is unstable anyway.. random freezes at settings like 10*250 2-2-2-10

So my question is, should i buy a newcastle 3500+, or an FX-53, or FX-55 or stfu and stick with my winnie

I really want something like 10*260 2-2-2-10 as memtest passes at this level

Im leaning toward 3500+ cost its obviously much cheaper

What is the big deal about being ""PRIME STABLE"". My AXP is running at ( and has been running at) 2400-2500 Mhz. At this speed my computer is not PRIME STABLE. I can play any game with no problems at all, I can run all kinds of other benchmarks (CPU stress) with no problem. I can loop 3D01 for days, run super pi and pifast till I am blue in the face---Again no problems. Computer never crashes, No BSOD's, etc..

You know what I do ?
I do not run Prime 95 on this machine.

You missed the point I'm afraid. Certain date codes of the 90nm Winchesters will not run Prime 95 at 200fsb. That is indicative of a problem and we are trying to troubleshoot that.

This really started with RMA's being requested for OCZ memory that was failing P95. If the CPU won't run it then the memory sure won't.

I am not an advocate of P95. I will say that I defend the rights of someone to have the option of using it to insure a conservatively stable system if they desire that. :)

Yeh i understand what you mean but my system does crash at most prime unstable levels

I would say that getting a 90nm 3500+ 0441 or later would be a fairly safe bet. This 90nm 3200+ 0441 runs P95 blend just fine so far. They may have mixed up the cores and some weeks 41's might still not run, we can't tell at this point although dnottiss has a week 41 that is failing.

I have a replacement 90nm 3500+ coming and will thoroughly test that when it shows up.

Interesting point. Some further testing along those should be done.

I will keenly be waiting to see that results. thx :)

Per my previous post, it also appears that some 3000+ >= 41 also are ok.

Has anyone received concrete conformation that the P95 code is somehow suspect (or not) with 90nm AMD products?

I have 2 CPU's, both 90nm Winchesters. Week 37 no P95 blend. Week 41 P95 blend runs 11+ hours so far. I used the same board, memory and settings. This is proof that the code is OK in my mind. We have aslo tried several past versions and a beta that has no P4 optimizations. No love on many CPU's.

Andy,
I can confirm that week 37 is a no go with Prime95. I pull my chip out today and it is:
ADA3500DIK4BI
CBBFD 0437WPGW

I can't not run Prime95 at all with the stock setting. Prime95 bombed out at one minute mark with blend test.

I will RMA my chip tomorrow... Looks like I will be spending my Xmas and new years with my old girlfriend.... Pentium 4 @2.4 533FSB!! :mad:

man you need to get out more lol just kidding

wish i rma'ed my winchester now as mine was a week 37 non primer and all, ah well its moved on now at a financial loss :mad:

Most of us are using the MSI K8N Neo2 Plat..Maybe thats the problem with prime ??

3000+ 0441 - A real joy in comparison to the last chip. Have not rebooted my computer in a week, including priming for 48+ hours, gaming, burning dvds, etc. Running solid @ 267x9, default vcore.

I think there is a lot of truth to this thread as I have experienced the frustration first hand. The first CPU must of been defective in someway as all other hardware with the exception of the CPU is the same.

I had missed this. Good to hear another confirmation.

I do want to say that I am not advocating mass RMA action. If you can live without P95 and your computer is otherwise stable you should do fine.

It's not like AMD will recall all these "bad" CPUs - :rolleyes: I've had 4 of these CPUs, one was clearly defective the other 2 sucked for overclocking. Really seems like alot of bad parts are making it to retail.

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

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. Have a 3000+ 939 .90 coming from Monarch this week - gonna roll the dice one more time ;)

Ok, after cleaning my chipset off that looked like this -

I went back to the basics, 280 x 9 and primed -

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

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... :toast:
