Basic Features: Athlon 64 90nm Processors
The new 90nm Athlon 64 processors were only introduced for Socket 939. Since 939 supports Dual-Channel memory, the speed ratings are a bit different than Socket 754 processors.| Athlon 64 Socket 939 - Specifications of New 90nm Processors | |||
| Athlon 64 3000+ | Athlon 64 3200+ | Athlon 64 3500+ | |
| Speed Rating | 3000+ | 3200+ | 3500+ |
| Actual CPU Speed | 1.8Ghz | 2.0GHz | 2.2GHz |
| L1 Cache | 128k 64k Code Cache + 64k Data Cache |
128k 64k Code Cache + 64k Data Cache |
128k 64k Code Cache + 64k Data Cache |
| L2 Cache | 512kb | 512kb | 512kb |
| Memory Type | Dual-Channel Unbuffered DDR | Dual-Channel Unbuffered DDR | Dual-Channel Unbuffered DDR |
| Memory Speed Supported | Up to DDR400 | Up to DDR400 | Up to DDR400 |
| Maximum CPUs | 1 | 1 | 1 |
It is interesting that AMD rates the 1.8GHz Socket 939 90nm 512k CPU as 3000+, while the Socket 754 1.8GHz 512k 130nm is rated as 2800+. Speed ratings for 939 chips are generally higher than their 754 counterparts. AMD believes that the higher performance of the Dual-Channel memory controller justifies these rating differences.

Can someone please explain the effects of raising vcore?I'm a relatively newbie to overclocking but I remember in the past (with Athlon XPs) raising vcore was almost certain death unless you had water cooling or your pc running in a freezer :)

Wesley Fink,could u make a screenshot of the Memory tab in CPU-Z of the 90nm A64 3000+ cpu ??
thx so much

Just got my winchester 3000+ and my MSI K8N MSI Neo2 Plat. Since it's an x-mas gift can put it together until then. Putting it with Corsair XMS DDR 400 memory. I'll let you guys know how it goes.Goomzz - Saturday, December 4, 2004 - link

I dont get it...1)IS 3500 64 voltage 1.5 Volts?
2)Looks like the decreased the CPu multiplier on 3500 coz by default it is 11? Why? Does it affect ur performance?

#82: it's been answered: get a board (MSI) that allows the Memory & FSB to run at an adjustable ratio, so the memory can run slower than the FSB.scius - Tuesday, November 16, 2004 - link
Cheaper Ram Altnernatives:A few other readers have mentioned this, but it seems there hasn't been much of an answer (though a few worthy attempts, notably that the 3200+ is probably a better choice).
The Question: What ram would let us run at the highest FSB for the least $.
Obviously you can just buy the faster stuff (DDR500, or whatever), but there must be sticks that, with looser timings(small cost), can let your processor scream(huge gains) while staying relatively stable.
Anyway, I haven't found any articles about it, but if anyone has, or has some personal experience here, i'm sure we're all eager to hear it.

Great article Wesley!cryptonomicon - Wednesday, November 3, 2004 - link
great article anand!The 90nm process sounds like a great improvement (especially for oc).
