Recently I found this AMD K6-2/333 in my basement, and I thought: "How in the heck did that get here?"

That's beside the point. Correct me if I'm wrong, but I think the 333 refers to the CPU supposedly being able to rival a P2-333 in performance, but not actually run at 333MHz. What I wonder is what's the corresponding FSB and multiplier for it?

Also, I'd like to know how much cache there is and if the cache has ECC or Parity on it or not.

If so, great. Then I might use it later to power a Linux server or something.

If not, then it's no good and then I'll try to sell it on Ebay.

I'd also like to know how much main memory is cachable with the cache on the CPU. If I were to use the CPU, the system would probably have at least 512MB RAM.

Talk to you soon!

ben,

You've got a K6-2 333, that's designed to run at 3.5x 95 MHz FSB = 333 MHz on 2.2 volts Vcore.
It has zero L2 cache.
I believe that it's got 64K of L1 cache.

The "ECC or parity" refers to your 'System memory', NOT the CPU's cache, so discard that avenue.

The "main memory is cachable" is more determined by the OS than the CPU, but a K6-3 is better in this respect.

What mobo?

even better a K6-III+ 450 overclocked to 600Mhz, it has 64k l1 cache and 256k l2 running at full speed.

Laptop:

it could probably be run on 133MHz x 2.5 too?

yes it could if the board supports it, but from what ive seen its not very likly. mabye it can be overclocked to 400Mhz either by multiplier or fsb...

-Milt-:

You really think that ECC or Parity doesn't apply to the cache? I'm fairly sure it does. My Opteron CPU (in my main workstation) has parity L1 cache and ECC L2 cache.

I also have a P3 where the L2 cache has ECC, though I don't know about L1.

But...I have a P2 chip lying around which does not have ECC on the L2 cache. Again I'm not sure about the L1.

So that's why I figured I was a worthy question to ask.

As far as what mobo it doesn't have one right now. It's just a CPU that's being stored right now. I thought I might want to use it later and get a SS7 mobo w/ >512MB ECC SDRAM support, but before then I wanted to learn some more about it since I didn't know much about the CPU (I think the system it was in was given to me). The mobo I had to throw away because all of the DIMM slots were broken so I couldn't put RAM in there.

I'm mainly interested because of all of the CPUs I have lying around it's the one with the best performance in a uniprocessor configuration (I have an extra P-Pro lying around, so...).

Everyone:

Any suggestions for what type of mobo I should get for it? AT or ATX doesn't matter, since I'd have to get another case for it. It'd have to support 100MHz FSB since I could probably safely OC it to 350MHz. It'd have to support at least 512MB ECC SDRAM, preferably using 256MB DIMMs. I also need an AGP slot and one or two ISA slots (I've got some ISA sound cards lying around, that's why).

Talk to you soon!

Ben,

You are correct in that 'cache' IS memory, but since you have absolutely no option to do anything about it, why worry?
WUSIWUG, and thats all there is. (WhatYouSeeIsWhatYouGet).
ANY K6-2 has 64K of L1 cache (32K instruction, 32K data), and zero L2 cache.
ALL K6-3 CPUs have the same 64K of L1 cache, but also have 256K of L2, which makes them much more advantageous when using large quantities of System Memory, and much better overall.

For a server, Linux or otherwise, you don't even need a vid card.
Any server can operate 'headless'.
Or, if you need to 'see' what's going on, even an ISA vid card will suffice.
So you DON'T need an AGP slot, not for a server.

For a mobo, I would strongly suggest that you take a look at what cowen1000, and the rest of the K6 crew here on the AMD Forums are accomplishing with his K6-3 450, on a Jetway J-BF530 motherboard.
The K6-3 450 never would overclock worth beans (it was the end-of-the-line for the K6-3 series, before the K6-3+ series took over), but he's got it running at 3.5x 133.3 = 467 MHz, and has now realized a 466% increase in performance from his identical-to-your K6-2 350
That all happened in this thread, and it is still on-going... we are hoping to get him up into the 744 MHz to 800 MHz range by switching to a K6-3+ 450

Cowen was a total 'newbie' when he started on this project, back in mid-June, so if he can do it, you can too.

Here's a screenie of my own K6-2 300 running at 400, so your K6-2 333 should be able to at least match this....

There was also a K6-2 333Mhz with a 5x multiplier to support mainboards which are limited to a 66Mhz FSB. I had one of these but ran it at 3.5x100 all the time.
