I am undecided between the 3500+ or the 3800+

Price is a minor issue. More importantly can i get the 3800+ to 2500Mghrtz air cooled to match a stock fx-53 and save the extra 125 which is an issue? Also, does the 3800+ run at 1000 hypertransport or 800. Thanks guys. Can i relistically get the 3500+ to 2400Mghtz?

I am pairing this this with 1gig Corsair 2-2-2-5 mem and an ati x800xt. thanks

Yes... I'm running my 3500+ @ 2.4 right now. You can expect a 3800+ to hit 2.6 easily.

the hypertransport link of ur cpu is 1600mhz for sure, but it really depends on ur mobo. so far the fastest ht link is 1000mhz.

2.6Ghz on a 3800+ ? really ? I was talking to a freind who says 130 nm tech might be able to squeeze 2.6Ghz as the last speed grade before 90 nm comes into play.

Mind you, theres a difference between overclocking a chip and fabbing one and getting a good enough yield from the wafers.

P4 Northwoods use a 130nm process yet went up to 3.4ghz. Mind you, it's not only the process that determines clock speed, the speed of the slowest step in the pipeline has an big impact too (hence amd's ability to keep up with intel at slower speeds). AMD have the althon 64 fx-55 rated in their road map as 2.6ghz, and with an fx-57 expected, I'm sure the core has a bit of room to move left in it.

yeah but the high IPC on the a64 stops it from getting to 3.4ghz like a P4, its easy to ramp a p4 up becaues its has a low ipc, its always been said on the axp that 2.2ghz was near the end of 130 nm not just the core, so to see 2.4 and hear of a last speed bump on 2.6 sounds intresting

Of course this was done on dry ice which means it is not a sustainable clock speed for an every day environment; a commendable feat nonetheless.

If money is not an issue between the 2 processors, logic would say go with 3800+ because it will probably have a higher overclocking headroom considering the extra 200mhz advantage off the bat.

My personal recommendation is to pickup a Newcastle 3200+ A64 @ 2.2ghz 512kb for about $260 and it will probably overclock to 2.5 on nforce3 250 agp/pci lock motherboard like Chaintech VNF-250 then you have $300+ left over to buy the new videocard you wanted so much or Raptor Hard Drive + a DVD-Burner perhaps.

2.6ghz should pretty much be cake for a 3800+ as long as you do not somehow land a poor example. There are a couple guys over at the xtreme forums that have topped 2.9ghz already and without extreme volts. 1.75v or so if I remember right. I bet that the 3500+ should be good for at least 2.5, probably higher as long as you have good air cooling and accomidating motherboard. If you can afford either, then I do not think you really can go wrong.

If the 3500 and 3800 are built on the same process, and the only difference between them is the internal clock multiplier, then surely they should theoretically be capable of exactly the same overclocking ceiling (though u would obviously need to increase the FSB/HT by a greater factor on the 3500 to achieve this) ?
