A64 3000 Socket 754 and ECS NF3 for $100 at Fry's

Got one. shipping today!

How does this compare to the similiar combo I got a few months ago with the Semperon 3100+?

I know my Semperon 3100 is an older 130nm die with a 9x multiplier vs. this new A64 3000 with a 90nm die, and 10x multipler.

Does the new onboard memory controller on the E6 revision (Venice) A64 3000+ give me a better chance of using 1GB DDR memory sticks, or doesn't it matter?

What is the best and cheapest 1GB DDR memory sticks?

I've located the following RAM for about $150, hoping to use 1 stick of each in each in my 2 ECS boards.

CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) TWINX2048-3200

Will this work with overclocking in both the Semperon 3100+ and the A64 3000+ ?
Hoping to use memory at 1:1, will this be possible? Or will I need the DDR 500 version?

With HTT at the max of 250 that means:
Sempy 3100+ = 2250GHz
A64 3000+ = 2500GHz
 
Chip runs hotter by about 3 to 5C but should should be able to best the 3100 by about 200MHz (2.5 to 2.6GHz with 512KB cache).

Have never had issue with 1GB RAM from Corsair, Kingston, etc.... Avoid non-name value stuffs. The Corsair VS was on sale a few months back for $65 AR.

The XMS should top out around 218 to 225MHz. My VS can hit 245MHz, although YMMV. I'd go with a 5:6 memory divider and use clockgen version CG-NVNF3 to overclock in windows if you need to more than 2.5GHz.
 
Thanks fur!!

Which chip runs hotter, the 3100 right?

I would think the Venice 90nm core (3000) would be a cooler chip since it's wattage is 51 vs. the Paris 130nm chip (3100) with a wattage of 62.

The other difference being the 3000 with an L2 cache of 512K vs. the 3100 with 256K.

I just ordered Corsair XMS 2x1GB kit (CAS 3) for $74AR per stick delivered, good enough eh?

Do you think this memory will cause problems with the older Sempy 3100 (Paris) onchip memory manager?

Not looking for large overclock, probably just to motherboard's 250HTT.
 
Hrm. Hard decision. I can't seem to find any info on it, but does anyone know about IRQ sharing on this board? The older board I'm using has some serious conflict issues with my cards, and even though the audio card and network card would be out, I'd still need the PVR150 and the PCI video card in there (and potentially a IDE/SATA card).

That and the price now is at a 'mid' point...wait until the 23rd...or bite the bullet and get this now when it's in stock :/
 
Have built many ECS NF3...no IRQ issue but I don't overload the PCI slots. The board has two IDE channels and two SATA ports. I'd go with the ECS NF4 754 (four SATAs) if you require more than two SATA drives.

The extra cache (+256KB) and core speed (+300MHz) probably account for the additional heat. Idle temp is 30 to 31C with 25C ambient.

The XMS should work with the 3100 CPU. I personally prefer the Corsair VS line.


 
Nice deal newegg is also has a free motherboard with amd 754's combos
biostar mobo+ AMD3400 is 115$ , there are a few choices
 
Grrr..tough choice. My 90nm Sempron 3100+ is running nicely at 2.56Ghz in a DFI NF3 250GB board.

Would it be worth it to upgrade to the A64 3000+, assuming I could get 2.6Ghz out of it?
 
If your DFI is a decent overclocker, you should be able to. I'm running my E6 Venice at 240x10. I think my memory is what is holding me back currently even though the ECS boards only have a 250 FSB max.
 
The ECS board is capable of +270MHz FSB if you auto load Clockgen CGNVNF3 during PC boot.

I'd keep the Sempron 3100 at 2.6GHz. Not much speed boost with the A64 @ 2.6GHz.
 
I guess I could give Clockgen a shot again. I had bad luck with my NF7-S with it, so I started basing maximums by what the BIOS would allow.
 
That ECS NF3 board has no problem running at 270MHz. Make sure you use only the CGNVNF3 version of Clockgen. Instruction can be found on the web.
