P3 650 FC-PGA cBO stepping SL3XV or P3 SECC2 cBO steppingSL3XK Best choice fro overclocking

[Toro 45]

Thinking about picking one up & wanted to know which one would be the best choice for OC'ing
Thanks, Toro

They should overclock equally the same. One of my friends has his 600e cB0 secc2 at 912mhz but uses expensive ram. Another friend runs over 700mhz with cheaper mixed ram [pc133 and pc100] on a 550e cB0 FC-PGA. The only difference that I can tell between secc2 and fc-pga, other than architecture is the cost, motherboard options, and overclocking solutions. FC-PGA seems like a cheap solution, but it really shouldn't matter. I was thinking about a 600e but will probably go with a 650e or 700e due to the cost of expensive high speed ram.

The FC-PGA format is a little more flexible in that you can put one in a Slot 1 mobo with a slocket, but you can't adapt an SECC2 to a Slot 370. You might work backwards and pick your P3 form factor after you've selected a mobo. Take a look at AT's Editor's Choice's for their fav's:

Anand's titles ID the chipset and slot/socket type for mobo's and CPU's. I think his favorite is the MSI/Microstar BX Master, which is Slot 1, has 6 PCI slots and 4 IDE channels with the superior Promise ATA/66 controller:

Take a look at the P3-700 fc-pga cB0 chip. I'm doing 933mhz no sweat.

Look at my sys. specs. al I had to do to oc. the chip was to set the
fsb.

I'll be using it on a Soyo6B+IV board or my BH-6. I'm mostly wondering if it's better to get the 650e variety.I see a lot of posting on that chip,whats the dif?Does the "e" variety OC better than the plain 650?

My retail PIII_650E FC-PGA does 975 stable (150 FSB) on my Abit SE6 board. I can only use one DIMM (even at stock 100Mhz FSB), which I think is related to the fact that I'm using ECC RAM, which has two extra chips to power and is probably overloading the RAM bus.

Still, 975 stable in games is nothing to sneeze at. I'll be getting another DIMM for it, non ECC, to see how it does.

Oh, it's Alpha'ed, of course, and running at Vcore of 1.8v. Stays in the mid 30's to low 40's C range.

Just my $0.02

Icestorm, what kind of temps do you get at a full load?

thanks

I'll have to play some CPU-intensive games on it and leave the temp monitor up. I normally don't see over the mid 40's when I check after gaming, but I know that the Asus monitor will show a dropoff almost as soon as I exit a game.

I have an OEM P3-650 cB0 Fc-pga, up to 975 @ 1.75 volts, PEP66, Asus P3V4x mb. 256mb Crucial Pc133 CAs2(running Cas2 @ 150 !).

My peak temps are, lately, 40 to 41, with mb hanging in around 34 or so. Its been hot out here lately.
