OK, I've decided to go with a 933 P-III processor. The only problem is there are two listed for P-III 933Mhz. The difference between the two-

(The only difference in mfg. #'s is 'U9' & 'C9')

Manufacturer-both Intel, Pentium 3, 933MHz
System/Front side bus speed-both 133MHz
Bus width-both 256-Bit to L2 cache
Level 1 cache-both 16K Instruction + 16K Data
Level 2 cache-both 256 KB
Socket type supported-Slot 1(U9)/370-Pin socket(C9)
Form Factor-Single Edge Contact Cartridge 2(SECC2)(u9)/Flip Chip-Pin Grid Array(FC-PGA)(C9)
Number of pins-242(U9)/370(C9)
Addressable memory-both 4GB
CPU Voltage-both 2.5V
Math-Coprocessor-both included
MMX Compatible-both yes
Superscaler-both yes
Floating Point Unit-both 80-Bit, IEEE-754 Compatible
Misc. Features-both Fan Heatsink Included, IEEE 1149.1 Boundary scan, Dual Independent Bus Architecture(DIB), etc...

Now, THIS is the motherboard I'm going with, unless someone can tell me a reason why I definitely shouldn't go with it. Looking at the two processors, what is the better choice for this motherboard?

Please help me out (once again)ON THIS ONE> I don't want to buy the wrong set-up.

Check out this ASUS board: http://www.asus.com.tw/products/Moth...uc2/index.html

It has a few more minor features, and it looks like it is a Socket 370 board rather than a Slot 1. The Intel looks like a Slot 1 from the picture on their site.

As for the difference between the CPU's one uses a slot form factor and the other a socket form factor. The U9 is slot, the C9 is socket.

I would go with the Asus board because I don't think Intel is making any more Slot 1 PIII's. Even if they are, I think the availability is higher for the sockets.

The i820 is a notoriously bad chipset. Look for a board that uses the i815 chipset like the Asus CUSL2. You want the flip chip package since Intel is phasing out slot 1 and all new P3 motherboards are using socket 370.

From what I understood all of the problems with the I820 had to do with motherboard manufacturers use of a memory translator hub to allow for use of SDRAM rather than the I820 suppored RDRAM.

It looks like the Asus CUC2 uses RIMM slots for RDRAM, therefore those problems wouldn't be an issue. Are there any other issues that you have heard of?

The only problem I can see using the I820 and RDRAM is the cost of the memory.

I 'normally' would like to use Intel motherboards, but in this case I will make an exception and agree with the ASUS recomendations.

here is a link

http://www.asus.com/products/motherb...sl2/index.html

you can find a good deal on pricewatch.com or shopper.com or pricescan.com

The 815 chipset is the way to go. Socket 370 or flip chip is the format to go with. BUT keep in mind some of this is pointless because when you do go with a p4 (when they get them right) socket form on your current board will not matter anyway.

I am looking at it from a bang-for-the-buck/resale/performance point of view, in today's market. This Asus board has made a name for itself and will be easy to sell off when you make the leap to the p4.


Go with the 370-Pin socket(C9) chip
and the ASUS cusl2 motherboard and you will be happy. Also, the Asus takes SDram pc133/100 which will save you a few bucks right now. RDram is a bit of rip off right now.

MAYBE PATMAN will comment on his new motherboard I know we talked him into one a month ago.

feenst - you are correct. There is nothing CURRENTLY wrong with the 820 chipset. I have 100's of them in use right now (even one on my desk at work) BUT IT ISN'T WORTH THE MONEY ON A 933 PIII!!!

MTH issues aside, even when you're using RDRAM, the i820 chipset is slow. It repeatedly gets crushed by the i815 on most any application benchmark. Part of the bad rep that RDRAM has gotten is due to this chipset since it in no way is able to take advantage of RDRAM's higher potential bandiwdth.

I'm putting off the P4 and just going for a high-end p3. As long as it keeps me happy for a couple years(I hope), I'll stick to the P3.

So, you say grab the Intel P3 933 (C9), and the ASUS cusl2 motherboard?

I recently picked up some Kingston RAM(PC133, DIMM CL3), can I use this on that motherboard?

That's what I did and it's a great motherboard with lots of user-provided support. There's even have a cheaper CUSL2-C model now that eliminates the onboard video. The board is great, the heat is minimal, and the tidier inside without that huge slot 1 monstrosity with fan and/or fins, is really nice.

Are you sure the core voltage of the FC-PGA is not 1.70? Even the newer stepping of the SECC2 form is listed at 1.70.

I was checking out the prices at www.accubuy.net , and they list 2 ASUS CUSL2's, actually, one's a CUSL2-C, and it's $14.50 cheaper. What's the difference in product???

Sorry guys, but I'm getting a little confused looking at all of these processors!

INTEL P III 933EB/256K/133MHZ SECC2 OEM CPU W/O FAN (45 DAYS WARR.) $339.95

INTEL P III 933EB/256K/133MHZ SECC2 CPU W/ FAN RETAIL (3 YEAR WARR.) $409.95

INTEL P III 933EB/256K/133MHZ SECC2 OEM CPU W/O FAN (1 YEAR WARR.) $369.95

INTEL P III 933EB/256K/133MHZ FCPGA OEM CPU W/O FAN (45 DAYS WARR.) $328.95

INTEL P III 933EB/256K/133MHZ FCPGA CPU W/ FAN RETAIL (3 YEAR WARR.) $374.95

...another dumb question. What exactly is the difference between OEM and CPU??? And I should get the fan also, right???

Sorry guys, still learning here!

You want the fan. It's the retail-boxed processor with a full three-year warranty. If you're not going to overclock the warranty will be good, but I never did have to use the warranty except in the old days when the Pentium-90, I think it was, had the floating point errors. They replaced it easily, but I think they replaced all of them, if people wanted, eventually.

How cheap do you want to go? You could save a few bucks with the OEM, add a fan, and live with less warranty.

I'm not worried about the price. What is the difference between the one that you suggested and the SECC2 w/fan?

...and what does OEM mean??

The SECC2 is the slot 1 form factor. If you get the Asus board, it won't fit.

OEM is the CPU supplied to companies that manufacture the whole computer so they don't need the box, might use a cheaper fan, and either provide their own warranty, or a lesser one than the three years.

Sometimes OEM can be dangerous because unscrupulous resellers were remarking them from a lower speed to a higher speed. I don't think you have to worry about that much now. I heard there's some of that going on in Germany, but primarily with the SECC2 form factor.

You're welcome. I made that same choice, but I went cheap with retail-boxed 800MHz for $210.

Yeah, I'm happy with the Asus CUSL2-C motherboard I picked up this past month. Other than that, I can't add much else but my thumbs up for the Asus MB. Have fun!
