OC'ing the Athlon 3500

Ok...no responses? I've already done a search for this issue on the OC forums, and didn't notice any threads pertaining to my question. I understand I need to keep the HT multiplier below 5 if I raise the FSB over 200 (HT doesn't like going over 1K). I still don't understand why it forces the memory down to 166 instead of 200 when I raise the bus speed to even 201 though. I would think there'd be a lock to keep it running 1:1 but I haven't seen it anywhere. Any info or even a stab in the dark would be helpful, thanks 😉
 
Ok nevermind about the actual OC'ing...got it figured out...I think. My question now is about an after market HSF for my CPU. I've looked around and read some reviews on different types and brands, but someone here might have a good idea... I'm looking for a heatsink (socket 939 compatible, AMD64 3500) that has at least a core of copper, and preferably a 92mm or larger fan, but that doesn't require a metal mounting plate on the underside of your mobo, and doesn't weigh 600 grams. Any ideas that I might not have seen? Feel free to throw em out there...
 
That's the smallest heatsink you'd want to buy, since you're overclocking. It's only like 5½ inches tall, and weighs ~600 grams, which is pretty light for a heatpipe, these days. Some of them weigh 1,000 grams.

Nonsense. There are a number of other heatsinks by Asus, Thermaltake, and Zalman that are lighter than this, and definitely shorter. The last system I OC'd, I used a Volcano 12. While it still weighed as much as a brick, at least it was a short brick with a relatively small footprint. I just want to know if there are any better options. OC'ing does not mean you need a monster HSF.
I'm not saying the Arctic64 isn't a good option, but I'm just wary of HSF's that have to stand a half foot off your board.

Oh really? I'd love to have a link to a heatpipe that's lighter than the AC Freezer Pro, which weighs the same amount as the non heatpipe heatsink that I used on my Athlon XP. The AC Freezer 64 that I own weighed just about exactly the same as the stock AMD heatsink that came with my processor. But, since you're the expert, I'd love to hear your recommendation to us all on which heatsink we should have bought.:laugh:
 
I don't know why you don't want a larger HSF - if it's for aesthetic or functional reasons, but if you ever get over that hangup, I really do love my Scythe Mine` - and it's whisper-quiet.

If you don't care about size, why didn't you just get the XP-120? It weighs less than the Freezer 64 even with a 120mm fan on it...I like the design of the Volcano/Venus 12s, and oh, actually, what's this? Yeah, you're right...a heatpipe cooler has to be huge and heavy...

I don't want a taller HSF that is going to put stress on my mobo, or will require modding my board to mount. I'm looking for simplicity. I'd rather not have to mount a backplate on my mobo, but I will if neccesary. I know that I have options if I don't want a backplate.

Because I already have a heatsink that easily outcools an XP-120.

That's a heatsink that will get you no farther in overclocking/keep you no cooler than a Volcano/Venus 12. So, why not just use your Venus 12, if you like it so much?
 
I don't have the Venus 12, I sold it with the rest of the computer I had it in when I parted it out. I just wanted to know if there were better options for the same design style before just buying another Venus, as the design is slightly dated now.
If the Freezer 64 doesn't require a backplate, then I'll probably go with that. Honestly, I expected that those Zalman models you listed would require a backplate just because of the weight.
 
You can find a 4-heatpipe stock Opteron HSF (I think it comes with Opteron 175 and up) on eBay for less than $15 including shipping. It's really decent and I ran my Opteron 165 @2.80GHz/stock vCore with it.

Yeah the stock Opty cooler is really good actually, though not quite so quiet @ high RPMs.

My 165 came with that one btw; i am pretty sure all Opterons come with the heatpiped one.

There are 2 types of heatpipe HSFs for dual-core Opterons. One with 4 actual heatpipes, and the other with 2 heatpipe snaking around the fins, looking as if 4 heatpipes. 😉

I think the heatpipes are copper, and fins are aluminum.
