Stepping

[Mort]

Please Help
I have a Coppermine 700 Flip Chip.
How do I tell what the stepping is ?
I know cb0 is best.
If I want to buy another CPU, can I tell then
what stepping is ?
PS..This one overclocks @ 115 / 38 on my
Asus CUV4X MB.

Thanks,
Mort

cb0's have an SL4XX code, ca's are SL3. Also, cb0's if retail say "dual prcessor capable" on the label on the box. Any questions check here:

Thanks Larry Joe, that is great.
Please verify,
any p3- 800 should run at 133+ FSB

2. There are no guarantees on overclocking. For o'clocking real men usually use 700/100 - 750/100 cB0 CPU's and try to get them to 933/133 - 1000/133 or better. Since even Intel is having trouble getting out enough 1000's you can expect it may be difficult for you to do that well, so people tend to not go for the 800 or faster chips to o'c where 800/100 > 1067/133 is not very likely, but costs more. Also, real real men don't try to o'c any P3 designed for a 133 system bus since they're already at 133 and so have little 'head room.'



P.S.
Any P3 800 or above should be a cB0, but as I suggested they may or may not do 133 or better.

"Real Men" LOL

I concur, stay away from the EB's. They are not for overclocking. Go with a 700E cb0.

Thanks,
When I said P3- 800 at 133 should work ok
I was asking, any Coppermine 800/100 should go to 133+ FSB
I understand that a 700 is better value,but it seems there is
no way to be sure of getting cb0 stepping.

To determine the stepping you have to ask the vendor to tell you the S-spec from off the outside of the retail box (or off the chip or the top of the SECC2 cartridge). Then check the s-spec against that chart. Some vendors vendors advertise the cB0 stepping 'cause they know it's desireable.

Check other threads for info on vendors with cB0.

Check vendors at:

Search Yahoo for " "cB0" "

I have found some cB0 P3's at http://www.gamepc.com

Onvia has 700e's, many of which are cb0's, for $215 after two coupons. You'll probably get a cB0 unless you live in or near California, since that warehouse seems to still have the older, less overclockable cA2's.

For the coupons check out http://www.techbargains.com and click on "Coupons" near the top.

Edit: I just realized that one of the coupons will expire in about an hour and a half, so you'd better hurry! You can still get it for $240 if you don't make it in time though...

Side note, not all cB0 chips say "SL4xx". OEM cB0 chips are all SL3Xx. Just to clear up any confusion with folks looking for an OEM chip to overclock. OEM cB0s are actually more common.

I have PIII 800EB/133 and it runs superb at 141+ mhz FSB with "PC 100 IBM 64MB RAM and PC100 128MB of some other brand RAM" They are bumped up 41 or more mhz in FSB increase!!!!!!! They are stable for sure, it's been running just fine 2 months now. I have no memory error messages or any other problems or crashing. I have also tried something CRAZY, I pushed the PC100 RAM sucker to 151 mhz FSB!! Then it finally said, nahh... litte witty bit too much. But I did not burn my mobo or any other components, LOL. So stop putting down on the EB version too much It still has quite a bit of reasonable amount or head room to go from 133FSB. I just found the Sspec for my PIII processor and turned out that mine is cBO stepping!!

- 800EB SL458 SL3XQ cB0 0683 256K 80 20.8 1,2,3,5,7

But Im still regret about I didn't get a PIII 700E with cBO because this has more potential in o'clocking. I would like to get my P3 800EB with ABit BE6-2 have flashed in the near future that will allow me to choose the ratio setting for overclocking as high as 180- 200+ mhz FSB, Haha... with the CPU case Air Conditioner attached. I am really hoping to reach 1.2 Ghz or more. Heh...
