Athlon MPs.

[Jon]

Have a question I've been debating over for the past couple of weeks and haven't really got a definitive answer after researching it thoroughly as there isn't a whole lot of information available on overclocking the Athlon MPs.

I am going to be getting Asus' new addition to the AMD dual board market and am a little torn in between which processors to fill it with. I'm aiming more towards FSB overclocking when I get it and only hope for as much as about 150MHz without fiddling with the multiplier unless I find I can get much more out of it.

Would the 1.2GHz not give a little more headroom for overclocking the FSB to 150MHz than would the 1.33GHz model? There isn't a whole lot of price difference between the two, $7 where I plan on purchasing, but even though it's a minimal difference I'd still like to save the $14 on two chips and just reach my goal. At 150MHz the 1.2GHz would be at 1.35GHz which isn't a tremendous increase but I figure it would do that before a 1.33GHz would hit 1.5GHz...general consensus has told me so far that the MPs don't overclock all that well.

What do you all think and which would you go for?

[Placid]

I would think the mp cpu's would overclock as well as thier t-bird counterpart all other things being equal(stepping).
I would also think it would be harder to overclock the dual cpu setup as high as a single cpu setup like with intel cpu's.

Since they are pre-unlocked as long as the motherboard allows changing the multiplier you could get 150fsb at default speed.

I believe that the MP's and XP's are the exact same chip, only the L1's are cut on the XP's and AMD offers no support/guarantee that XP's will run in SMP. As far as MP's not OC'ing well that is inaccurate. They are the same and should OC the same, it is just that most people with single CPU set ups do not spend the Xtra $ for the MP, although some people should since they have no clue on how to unlock an XP. Now the Tyan Mobos that are out offer no OC options at all, therefore the MP in SMP is really untested as far as OC'ing goes. Personally out of the 2 I would get the 1333 because it has the better chance of reaching a higher OC then the 1.2. In my experience the XP 1600's seem to be the best OC'ers of all. I would then get the MP 1600. When the MP 1800 first came out www.amdmb.com tested them in a single cpu setting and it OC'ed just like it's brother XP. Hope this helps.

May just go with the 1500 then. Not much difference between the 1.2 and 1500 but when you get to the 1600 it takes a bit more of a price hike. 66MHz isn't worth an additional $10 to me.

I'm not too intent on getting a high CPU speed but really want to get as much out of the bus as possible. Not going to be easy with 768MB of ECC but I'm going to give it a shot.

If all fails then it may make the most sense to go for the 1.33GHz if running at stock anyway...an extra $7 a chip really is nothing considering the parts I need to get still are going to run me over $700.

well i have an xp 1500 at 1.6ghz on an asus a7m266 so i would think that if u are going to get the asus a7m266-d with an mp 1500 the results shouldent be that different

edit: oops lol i ment a couple mp 1500s:burn:

I would go with a mp 1500. I am running the 1.2ghz mp's which overclock very well as you can see but the $7 difference seems worth it to for the 1500. I am not sure how they overclock though.
