Mobile Barton + NF7-S Rev 2 and CPUID

Quick question for you guys, if I was to buy a mobile 2500+ and install it in my NF7-S Rev 2 motherboard, would I still have the option to set it up as a 3200+ (one of two quick setup options I have with my current CPU) in Softmenu as I can with my desktop 2500+? And would the NF7-S R2 recognize the CPU as a 3200+ if I was to set it manually to 11 x 200?

I'm considering selling my unlocked desktop chip and buying a mobile version and running it at 3200+ undervolted to reduce system heat. I was thinking that if so many are hitting 2.4GHz and up at 1.7V that I might be able to pull 2.2GHz at 1.5V or so. What do you all think?
 
WinXP (sys properties) shows Unknown CPU Typ. Cpu-Z shows AMD Athlon XP-M for the name and Unknown CPU Typ for the specification.

Sokratz.
 
Mega, what specifically is your concern? Oh, and the bios will not recognize the CPU at all and will only allow "User Defined" in the Soft Menu - CPU Operating Speed. Now this is my understanding as of bios rev 22. I have not loaded 23 yet and it may recognize the CPU properly.

I think he wants to sell the mobile Bartons as if they were barton 3200+ to noobies 😉

My XP 2400 Mobile is doing that right now, without effort. It is shown as an "unknown CPU type" in System Properties.
It seems it did properly define it at stock settings?

naw, mega's a good trader... he wouldn't be stupid enough to try that...

.. right? 😉
 
I certainly wouldn't defraud anyone. This is for my own use. Shimm knows, it's his old NF7-S that I'm still using and plan to use until I can get a NF3-250Gb Ultra Socket 939 system. Then my wife gets my NF2 system and the kids get her KT266A system. And so on. 🙂

I only ask because I'm very anal about things (it's my nuclear Navy training) and I want the CPUID to show properly for the right FSB and mult. I also had an unfounded fear that if the BIOS and Windows doesn't see the CPU right that certain features would go unused (the cache and so forth). As I said, it's unfounded but it did occur to me to worry about it. 😱

I've been running my desktop 2500+ for almost a year now as a 3200+, I like seeing 3200+. 🙂
 
I wonder just how much faster it really is. On my desktop 2500+, I can do 2.3GHz @ 200MHz FSB @ default voltage. I haven't pushed up from there yet. I guess there may be little reason to buy a new mobile chip in this case. 🙁

Wait, let me guess-- but you aren't running it at 2.3ghz, even though it will do it at default voltage, because the bios doesn't recognize it as an XP3200?

Correct. 🙂 And the extra 100MHz doesn't seem to make that much a difference in the games I play. Now when I start to put my VHS library onto DVDs it might... I may have to push the CPU up a bit more then.
 
I get more gaming improvements from overclocking my Radeon 9800 Pro to 420/360 than I do from increasing my CPU to 2.3GHz (from 2.2GHz).
 
Mine does 2.5ghz as well, and the most computational stuff I do is gaming (yah) and 3D Studio Max professional renderings. Ripping DVDs in DVD Shrink also.
 
Ok, I bumped the FSB up to 210MHz and lowered the mult. to 10.5. Still 2.2GHz but the system sees the chip as just an Athlon, not an AthlonXP. I'll post up a Super PI score soon.
 
Ok, so this time I lowered the FSB back to 200MHz and upped the mult. to 11.5 (2.3GHz) and this is what I got for Super PI:

1M in 43s
2M in 1m 38s

So, it's 100MHz faster and only finishes Super PI 2 seconds faster. Memory throughput according to EVEREST is 200MB lower at 200MHz FSB, so I think I'm gonna stick with 210 x 10.5 (2.2GHz) for a while.

I fold proteins 24/7 with it at that speed. Here's the screenshot of it passing Prime95 for 12 hours, with only large fft's (roughly the equivalent of running the "normal" blend torture test for 5 or 6 days): link.
 
I'm Priming now with Ver 23.8.1 using the method with max FPU stress (I've already checked my memory using Memtest86). It's been running for a while now, I'll let it go overnight and through work tomorrow. If it's still running then I'll call it stable and adopt it as my new CPU setup.
 
Were you aware that using small fft's is totally useless, unless you suspect that you have a bad cpu? What you're running now is only testing your cpu and it's cache, nothing more. You would be much better off running either the blend torture test for a few days, or the custom torture test for a few hours, with a minimum of 2048 and a maximum of 4096.

Out of curiosity what are your prime95 benchmarks?

Mine:
Best time for 384K FFT length: 21.900 ms.
Best time for 448K FFT length: 25.008 ms.
Best time for 512K FFT length: 26.907 ms.
Best time for 640K FFT length: 36.193 ms.
Best time for 768K FFT length: 43.075 ms.
Best time for 896K FFT length: 51.802 ms.
Best time for 1024K FFT length: 57.308 ms.
Best time for 1280K FFT length: 75.543 ms.
Best time for 1536K FFT length: 89.753 ms.
Best time for 1792K FFT length: 109.317 ms.
Best time for 2048K FFT length: 120.866 ms.
 
I ran the benchmark, but I can't remember what the numbers were, since that was more than a week ago. I'll run it again, but my numbers won't be as good as yours, since at the moment, I'm running ram that will only do 2.5-3-3-11, instead of 2-3-3-11 (not to mention the 150mhz processor difference).
