I'm near a heat source in the winter. There's no other way.



I run the AC, which is right next to the heat source that I keep off in the summer. I haven't noticed any probs with my P3-500. I want to dump it for an NF7-S and either a 2400+ or 2600+ with the same case, PS and fan setup.



Thanks

You're going to at least need a new power supply with a 4-pin 12V ATX connector.

Heat isn't much of an issue with these chips as long as you have a decent HSF unit. Of course, that's assuming you're not running it at 2.0V.

It sounds like your current case is very old and outdated. You're best upgrading to something with a newer (P4-ready) power supply and better airflow. Check out the Cases and Cooling forum for lots of great advice. Both intake and exhaust fans are practically standard these days.

 

[Interitus]

Have any of you guys tried undervolting these yet? I know their default voltage is 1.45v.

I was going to purchase one to run it at 1.45v at stock speed sheerly for the lower heat and ability to run very slow and quiet HSF's on them (i.e. a Zalman 7000 keeping temps in the 30's at 5v)

I do have a good set of DDR400 that will run 2-2-2-11 @ 2.6v so I was looking at running a mobile (don't matter what speed, but preferably a 2500 or 2600) at stock speed by changing it to 200FSB and a very low multi like 9 for the 2500. I figure it will do this no problem but...

Will the mobiles actually pull stock speeds like this at the 1.45v? Or is their 1.45v rating strictly for the 266 bus and stock multi?

Anyone out there with a 2500 or 2600 mobile that can try that test for me?

(200fsbx9) for 2500 ...I guess 9.5 would be 1900mhz and closer to true stock...

or

(200fsbx10) for the 2600

If you can, PM or post the temp result change and if they'll actually do this at 1.45v.

Thanks!!!

Ok, it's down to the NF7, NF7-S, or the AN7. I like the extra 2 USB and 1 frewire ports on the AN7 and won't use the SATA on it or the NF7-S. I have an Adigy2 I am happy with, so onboard sound isn't that important. Everyone recommends the NF7-S but the NF7 is $26 cheaper and I could always get a Firewire card. Is the only difference in the NF7-S and the NF7 the add-ons? If so, the NF7 would work just as well as the NF7-S. Which should I get?

RCraig

Hey RCraig.

I ended up with the AN7 and its a hell of a board. so far i'm doing 215x10, but i'm just getting warmed up..

i have one glaring issue with it. No MBM support. long story short: Asus Taiwan wont let Asus USA give Alex V. K. the API so that he can support uGuru boards in MBM. and that just sucks. because now in order to have any temp monitoring, you have to go with their uGuru/AbitEQ program, which tells you temps...but is no MBM by a long shot.

other then that, i'm pleased as punch.

Interitus,

You said, "I was going to purchase one to run it at 1.45v at stock speed sheerly for the lower heat and ability to run very slow and quiet HSF's on them," and that's exactly why I bought a Mobile Athlon. The way I see it, even if I'm using a great CPU cooler, I still want to keep heat production itself to a minimum, so I don't intend to run my processor at maximum speed.

I'm not sure if this will answer all of your questions, but here are my results with an Athlon XP-M 2500+, a Shuttle AN35(N)-Ultra, an Antec 300W power supply with a "Smart" fan, a ThermalTake Volcano 9 heatsink fitted with an AeroCool 2000rpm fan (it's not very efficient, but it's QUIET), and 512MB (2x256MB) Corsair "Value Select" Dual-Channel PC3200 DDR-SDRAM.

Setting 1:
8x200MHz=1600MHz
1.25V Vcore (14% decrease)
36 degrees C at idle
42 degrees C under Prime95 stress-test (6 hour minimum)
NOTE: I usually run my system this way.

Setting 2:
11x200=2200MHz
1.45V Vcore (standard voltage)
POSTs but does not boot into Windows 2000

Setting 3:
11x200=2200MHz
1.60V Vcore (10% increase)
43 degrees C at idle
59 degrees C under Prime95 stress-test (6 hour minimum)
NOTE: I run my system this way when I really need the processing power.

Setting 4:
12X200=2400MHz
1.75V Vcore
does not POST due to inadequate cooling

NOTE: My CPU will apparently run fine at 2400MHz if I use a larger (and noisier) cooling fan, but I haven't tested it with Prime95 and I suspect it might not pass a rigorous stress-test. I haven't forked out a lot of money for a really good but QUIET CPU cooler, so for my purposes, there hasn't been a good reason to run a lot of time-consuming tests.

As you can see, my CPU can run with less voltage at stock speed (with a higher processor bus speed), but significant overclocking requires a voltage increase. Judging by the numbers, my CPU might be able to run at 2000MHz (a 25% increase) at stock voltage, but I haven't tested it.

Individual CPUs yield different results, so it's probably worth your while to buy your own and do your own testing to see what kind of results you get. Good luck!

 

[daba]

It's even cheaper now. 2400 = $94, 2500 = $99!

Get an SP-97 and a Vantec 92mm Tornado with this and you're good to go!!!

 

[ahsumdude]

I have a 2600+ IQYHA 0346.

I have had it up to 2600 Mhz but not stable on my A7n8x deluxe because the max vcore is 1.825v.
I ran it at 2500 mhz for weeks at 1.775 however I got tired of the fan noise in my case. Currently I have been running this processor at the lowest voltage setting which is 1.575 on this MB and my CPU is prime stable at 2320 MHZ. CPU temp runs around 31C to 35 C. This CPU is certainly not the best OCer but runs fast and furious at a low voltage.

Though if I have to hardwire the multiplier, I might just wait until I can go Nforce2.

I looked at the same option as you have since I have similar spec with you (8kHA+, DDR266, XP 1600+). Officially EPOX doesn't support mobile Barton. Secondly, there has been some people who reported that they could install mobile Barton on 8KHA+ but I'm not sure (See EPOX at AMDMB.com forum).
Some said that 2400+ throurobred(??) will hit higher speed than Barton core so I'm also postponding my decision now.

These are actually VERY close to what I would run the processor at. I really had my mind set on running very close to 2500+ stock speed (1.83) so I guess that leaves me with either 200fsb x 9 or 9.5 multi. My case has very very good airflow so I should be able to keep about where my temps are now with a big decrease in fan voltage. I have an extra 120mm coming in soon and will have the adapters/cabling to run every fan in my system at as close to 5v as I can get them to start up. This is what I'm working with now...


Antec Sonata with Bezel cut open larger for better airflow
Thermaltake Silent Purepower 420w
Abit NF7-S 2.0 (no voltage mods) w/ stock NB cooler on a Fanmate
AQXEA 0331 Barton @ 3200+ @1.62v
Zalman 7000A-AlCu on Fanmate
1GB OCZ Platinum EL @ DDR400 2-2-2-11 @ 2.7v
WD800JB Primary
WD1200JB Storage
Stock Antec 120mm rear exhaust on a Fanmate
Panaflo 120mm (non-hydro wave) on drive cage (soon) also on a Fanmate

With the system running at 3200+ I get about 40C Idle with the Zalman (It doesn't fit on the NF7-S like it's supposed to otherwise it'd probably be around 36-37C idle) which isn't too bad, but I have to run the Zalman full speed to achieve those temps. I'd really like to tone that thing down to at least 7v consistently without hurting temps at all.

Basically it sounds like it's a great deal all in all and would really benefit my system to jump on the mobile bandwagon...

Now does anybody want to trade a very nice AQXEA desktop 2500 for a mobile? C'mon I know there's someone out there hehe...

How did you find out they don't support the Barton? Has anyone said that they could not get one to work? According to one thread there, since the board doesn't have a multiplier above 12.5, you must use the app CPUMSR to get higher multipliers. Is that a big deal? Maybe that's what you mean about the Bred running higher than the Barton? Else I don't see how the Tbred would overclock better.
Supposedly one person mentioned there flashed a KT333 BIOS in a KT266A to get a 1/5 divider?
Even if it does work, I definately need it stable.

A few people over there claim the 8KHA+ supports 333FSB CPU's.?

There was a post from EPOX support. You can also find the CPU which 8KHA+ currently support from EPOX website. I saw someone talking about Barton "Mobile" installed on 8KHA+ but I could be wrong.
As far as I know there's not a bios update which supports 333FSB, is there?

 

[huesmann]

I came late to this thread and have some questions.

Can I just replace my desktop 2600+ with one of these mobiles and get a lower temperature at stock clock speeds?

What's the tradeoff? Is there any disadvantage to doing this? Is there any performance loss?

no tradeoff, and it should get lower temps at stock speeds since the voltage has gone from 1.65v in the desktop chip to 1.45v with the mobile.

no performance loss, no disadvantage....but if you're not overclocking, i'm sure your current 2600 is serving well.

I myself have ordered the 2600+ mobile and have a 8k5a3+ Epox

Link to my previous post

Though, at 166 with 16x, even at 1.9 or at close to 2 volts, the temps are HOT. Stabile at less than 50% cpu load when using Task Manager. At 100% load, it will reboot after 5 minutes.

I suggest to give the wire mod with a multiplier less than stock if you are using 166.

 

[edplayer]

Interitus, I think almost all the mobiles Bartons should be able to do 1800MHz at 1.40V

Subodim, nice post. Can you try some settings in between?

I have been trying several different settings (though not recording temps) and right now I am testing out 1980MHz (9x220FSB). I was at 1.50V and I lowered it to 1.45V yesterday. SO far stable and if it remains stable I will test out 1.40V in a week or so. I have a Thermaltake TR2M2 so I don't expect the lowest temps. I will post my temps when I get more info

For those posting temps, please include what kind of heatsink/fan you are using and what are your average room temperatures.

Assuming that your motherboard can run a Mobile Athlon (not all of them can), you would probably get a lower CPU temp at stock speeds. Look at it this way. A normal Athlon XP 2600+ can be expected to generate about 68W of thermal energy. But an "Athlon XP-M 45W" (that's the formal name) can be expected to generate about 45W of thermal energy. In other words, it generates about 33% less heat. That should make it run cooler, although the rate of return is probably marginal--it will put less heat into your room, but if you have a good cooling solution that dissipates heat very well, the temperature on the CPU die will only change by a few degrees at most, if you follow me.

I don't see why there would be any performance loss. What we're really talking about is a Barton that is "cherry-picked" at the factory because it can run at a lower voltage and put off less heat than an ordinary Barton. It is given different markings on the chip and a different CPU ID string--and the multiplier isn't locked--but other than those things, there isn't really any difference that I know of.

The trade-off is that the Mobile CPUs are slightly more expensive, their availability is limited, and not all Athlon XP motherboards can run them due to recognition issues, voltage issues, etc. Your motherboard doesn't necessarily have to identify the CPU correctly in the BIOS (mine doesn't), but it needs to support the required multiplier and voltage and so forth.

 

[huesmann]

How would you know whether or not your mobo can run a Mobile? My oldish Epox EP-8K3A+ has CPU voltage settings down to something like 1.30V and up somewhere above stock XP voltage. Would that do?

 

[Subodim]

Subodim, nice post. Can you try some settings in between?

Which settings would you like to see?

I did a test to see if my CPU can run at 2000MHz (10x200MHz) at stock voltage. I tried it immediately after doing a Prime95 stress-test, so the chip was "warmed up". Unfortunately, it wouldn't boot at 1.45V. It did boot at 1.55V, but I didn't do any stress-testing or try anything in between.

I figure that my CPU wouldn't have any trouble running at 1833MHz (11x166MHz) at stock voltage or slightly less. I'll give it a try and let you know.

By the way, I'd like to reiterate that my goal is to have a quiet system that doesn't put off lots of heat (without spending a lot of money), so I'm using a limited amount of cooling. I have a large CPU heatsink with a low-RPM 80mm fan, and a low-RPM fan in my power supply, and that's it. (My video card and motherboard chipset have passive heatsinks.) I'm using an old Inwin S500 ATX midtower case just because it's an old favorite. The ambient temperature in my home-office is about 74-78 degrees F. To get better performance from my system, I'd have to replace the fan on my CPU cooler and probably have to install a case fan.

That's not easy to answer. I suggest that you do some research and see if anyone else has already tried to run a Mobile Athlon on the same motherboard. But in my own case, I couldn't find any information about the two motherboards I wanted to try, so I had to buy them and see for myself. (Fortunately, I have no trouble selling parts and systems if I want to get my money back.)

If your motherboard can run a Barton CPU, you might be in luck. Your BIOS probably wouldn't recognize a Mobile Athlon, but that's not necessarily a problem (I don't know of any motherboard that actually does). From what you've said, you probably wouldn't have any problems adjusting the voltage, which is good, but that would leave the issue of the CPU multiplier. If the motherboard can only run the Mobile Athlon at some unreasonable default setting, you probably wouldn't be satisfied with it. (That's one of the problems I had with one of the motherboards I tried.)

I have an Epox 8K5A3+ and a mobile 2400+ but kept getting a blue screen saying "Harware failure, contact vendor." Others have reported this same problem. I pm'd EpoxTech and he told me to "Look in the BIOS for Athlon 4SSE and disable it. It should solve the stability and error message." This worked partly, I could then get to the desktop and it ran without a load all night, but started blue screening after I started running apps. I was running it at 1.7 core and 133x14, but CPUID said it was using a 5 multiplier. I then upped the FSB to 166 and it showed a 14 multiplier in CPUID, but started blue screening again. I replaced my 1600+ back in this board and ordered a new board. I haven't heard of anyone who has a fix for this board with the mobile cpu, though the regular Barton may work better. FriedRiceBob tried a mobile in two 8K5A3+'s and had the same results.

Hope this info helps.

[tchinhe]

After almost 2 months I finally had a chance to install my 2400+ and NF7. it is set at 1.5V and 200x11 right now. installed xp fine. Will flashing the BIOS make it recognize the CPU or it will still show as unknown.

 

[papaschtroumpf]

I have been menaing to buy an XP3200+ so can I instead buy a 2500+ or 2600+, and change the FSB to 200?
Is it pretty much guaranteed to work?
I was thinking about getting a A7N8X motherboard (rev 2) to go with it but I'm open to suggestions. Basically I am not interested in overclocking the buses. I want my PCI to run at 33 and the AGP to also run at stock speed, and I want both emeory and FSB to be at the same locked speed (min 200).

 

[huesmann]

Thanks, I've ordered a Mobile 2600+ and will give it a whack. It's only $99 to try.

 

[Subodim]

I just did a test with my Athlon XP-M 2500+ (Week 52 2003):

11x167=1838MHz (same as Athlon XP 2500+)
1.40V Vcore (3% below stock voltage)
39 degrees C at idle (20 minutes after running stress-test)
47 degrees C under Prime95 stress-test (6 hour test)

 

[Interitus]

Sub can you try running it at 200fsb and 9 or 9.5 multi @ 1.45?

Also what HSF are you running?

Thanks!

Thanks!

9.5x200MHz=1900MHz
1.45V Vcore (stock voltage)
41 degrees C at idle
51 degrees C under Prime95 stress-test (6 hour test)

NOTE: The room temperature is about 80 degrees F now, which is about 4 degrees higher than it was when I did my earlier tests (because I've been running stress tests on three computers all day), so that probably accounts for a small increase in CPU temperature. Even so, I would say that raising the FSB speed from 166MHz to 200MHz appears to make the CPU run 1 or 2 degrees C hotter even at a similar speed, which confirms what 87pathfinder said earlier.

I apologize for repeating myself, but I know there's a lot of messages to wade through in here. My CPU cooler consists of a ThermalTake Volcano 9 heatsink fitted with an AeroCool aluminum LED 80mm fan. According to MBM 5, it runs at about 2300rpm. It is rated at 21.5 CFM and 20.3 dBA, and it is is quieter than my Hitachi 160GB hard drive.
