dual processor amd mp?

lostguy30 · Jul 5, 2002, 05:40 AM

hello all, been lurking around here for a bit and you guys rock, taught me plenty just reading your posts. ok real reason for posting, havent seen too many dual processor overclocking posts, right now have a single xp 1900, but just for &%^$ and giggles im gonna build a dual mp 2000 system and thought about overclocking , if possible/feasible. any thoughts/ideas? again thanks for all the info guys, again great work here and appreciate it. rock on.

Ya nose is a little brown there, buddy.

Firstly, do not get a Tyan board. The Tyan dual board is aimed squarely at the server/workstation market and is built for stability. As such, you'll see next to no overclocking options. ASUS's A7M266-D, however, has quite a few -- such as FSB adjustment up to 180MHz and voltage tweaks. MSI's K7D Master allows for FSBs of 133, 138, 140, 144, and 150 and allows for voltage tweaks, as well. Neither of these boards will let you apply a voltage bump to just one of the processors, but I don't see why you'd want to do that anyway.

At this point I'd like to take an opprotunity to say "Just say Asus."

Anyway, try to get CPUs from the same batch. It's not a guarantee, but same-batch proc's have a better chance of o/cing equally. Since clockspeeds have to be the same, you don't want one capable of 1.8GHz, but another only capable of 1.7GHz, you know what I mean?

Another tip? Get one big bad punch-yo-momma-in-the-eye power supply. Do not skimp. '

Other than that, stick with the basics. Get good HSFs , buy high-quality RAM, and have good case cooling. Especially considering you're going to have two heaters in your case instead of merely one.

And, really, get a badass power supply.

I really hope that helps! I EAGERLY await the results of your experiment!

javafox, thanks for the input, was just looking at asus a7m266-d this morning, actually found it on sale and grabbed it. glad i didnt take tyan board after all. and gonna watercool for sure. will let all know what i achieved, as a beginner of course...
btw.....(wiping nose) thanks of course.

Just to add to comments. Really, really do get a big ass PSU, and make sure you have good case cooling, not just good HSF.

Any dual CPU solution builds up a LOT of heat internally, and this needs to dissipitate, otherwise you stress out the other compents; e.g. gfx card. Yeah, you might have a fan on the card, but that is only circulating already warm air.

One of the sites, Tom's, Sharkey or Anandtech, had a good article on cases cooling. It's not so much the number and power of fans, but ensuring a good airflow throughout the case. eg, in one fan and out from another, ensuring the air circulates through the whole case, otherwise one ends up with pools of cold and hot air.

My servers are home are dual PPro systems (boy, do these get hot), and dual P-III workstations (keep meaning to buy a dual AMD solution, when I run out of horsepower).

Hehe, I guess my double-mention was inadequate?

lostguy30 · Jul 6, 2002, 03:21 AM

oh, so i need good cooling?

Ummm... yes a Enermax 650 would do you good.

But i wanted to point out that there is no use in getting a dual system. Quite frankly there is no performance gain when using the dual mp's with an MPX chipset, there just simply isn't enough memory bandwidth for the two processors. You would have much better (gaming) performance with a KT 333 or 400 based single processor solution. The only performance gains on a dual system appear when you are running a server or a rendering farm or something really intensive, and in 99.9 percent of the time you really need stability there.

So you see overclocking a dual system is like putting racing tires on an 18 wheeler. Its just unsafe and doesn't give you any performance boost.

Just my opinion, but if your set on getting a dually system then go for it.

And get some cooling for that chipset too!!!

Although I'm sure that you know personally five people who have benefited from active chipset cooling, I don't buy it, just like I don't buy heatsinks on system RAM. I don't think it'll do a damned thing, really.

It's only useless from a gamer's perspective. But I agree, that's a misconception many people make.

But we don't know what our "lost" comrade here plans to do with his rig, so let's not be so quick to discourage him.

Overclocking, when done right, can yield a perfectly stable system. My 1.4GHz Thunderbird, for example, runs happily at 1.53GHz, and I simply do not have instability issues. If lostdude wants to get a dual, let him; if he wants to squeeze every last pit of performance out of the machine, let him do that as well! As long as the system is not mission-critical (that is, it's running life-support in the local hospital or controlling the city nuclear power facility), and our friend is careful and thoughful, I see no reason with overclocking. More power --no pun intended-- to him!

Speaking of computers and mission-critical environments, check out this thread:

thanks for all the advice guys, already got half the stuff ordered and just cant bring myself to quit now, as for this rig, yeah its for #$%@ and giggles. just something for me to play with. expensive game....yeah, but thats half the fun, risk. and one last question, why cant you put racing tires on an 18 wheeler?

the proposed rig: dual 2.0 gig athlon mp, asus a7m266-d, 768 pc2100 ddr, 200 gigs of hard drives, cdrw-dvd drive, ati (havent decided which yet), 650 psu, d-tek dual cpu watercooled.

if ya here something go boom, ill be ok in a bit.

S&G is as good a reason as any. If you aren't havin' fun, what's the point?

At least, that's what I say.

Yes, ensure that you source the largest, most powerful, titanic PSU you can lay your hands on. From a respectable maker, too.

Just checking...lol. Oh, and good choice not gettting the K7D Master. Friend has one and says it is SH*T for OC'ing. Very stable board, but not an O/C'er.

good luck
