A PII-300 that is likely to be a PII-450
Remco G
Last Saturday I bought a new system with a Pentium II 300, but astonishing enough, the system recognizes the processor as a Pentium II 450. This is on the screen while booting. After having checked the serial number on the processor, 80523PX300512PE 18320505-0464 SL2W8 , according to the intel coding system, it must be a PII-300.
Several test programs reported a ' Genuine Intel Pentium II-450 MMX with ECC running internally at 451.1 Mhz, and externally at 100.3 Mhz'.
Is it possible that the serial number is corrupt? The last 5 coding chars, SL2W8 is according to Intel a 300 Mhz core and 66 Mhz exterieur. But the SL2WB is a 450 MHz core and a 100 Mhz external path. I double checked that code. Does anyone know more about this strange case?

Hello Remco,
it would appear that the person that installed the processor
for you configured the processor to run faster than it is
specified for.
The 300MHz processor is specified to run 4.5 times the 66MHz
operating frequency of the motherboard, while the 450MHz
part runs 4.5 times 400MHz. Running the processor beyond
it's specifications is considered overclocking, and voids
the OEM processor warranty. Make sure the company who sold
the system to you in this condition is willing to warranty
the processor for you.

1800MHz? I like it, typos aside, does is come with an air conditioner
attachment, do we need to vent to the outside, will 6" pipe do? ;-)))))
(That was supposed to be "the 450MHz part runs at 4.5 times 100MHz", right?)
Vic ... ;-)

a improper setup alone. But if you are using reliable test programs that get
the data from the CPU (and not from the configuration settings) then it might
be OK. This is because at least previously like with the Pentiums if Intel made
too many of a faster CPU then demand existed to buy it they might just mark the
CPU down and sell it (well it beats little demand resulting in its sitting in
the warehouse and never getting sold), but they might not do this anymore. You might
be lucky, but until you have absolutely ruled out that it is just a misconfiguration
either in BIOS or in jumber, I would absolutely set it back to a 66 MHz bus. Only then
(while running at a 66 MHz bus) a reliable test program that gets the data off of internal
information provided in part this is indicated as a 450 would I set it back up to 450
again. Best not to continue to run it at 450 MHz unless you can be absolutely
certain that it is really a 450 MHz PII that was marked down. Marked down from 450
to 300 sounds less likely though then from 333 to 300.

I heard that in order to accomodate the shortage of PII-300 CPUs out there
Intel basically rebadged and configured a bunch of PII-450s as 300s. Produciton run of about 14 days. Apparently the have 2.0V on the case markings and also if you cover up pin 11, it performs as it was built - as a 450Mhz CPU. Note this is not overclocking.

processor that is actually a deschutes core 450. Abit BX6 and BH6 board
owners just use software bios to set the bus speed at 100 (the mulitplier is
locked at 4.5) and presto! instant PII 450 for $250 instead of $750. 504 mhz
has been achieved in quite a few cases. Those with Asus boards have had the
same success by covering pin 21.

Hello Giri,
running the processor beyond it's published specifications,
those of the factory markings on the processor cartridge, is
considered overclocking.
Overclocking, as well as making any physical alterations to
the processor to affect it's operation, is not supported or
validated by Intel. It can result in undependable system
performance, data corruption. It shortens the life of the
processor, and voids any processor warranty.

PII 450 (for the most part) and sold as a PII300 (good deal huh!) I have
one myself. The multiplier is locked at 4.5 you can't change that (4.5x66
mhz= 300). Plug it in a 100mhz board as you have and this processor shows
its true colors. some have had success at 504mhz.

To get it to run at the 300 I need to lower the bus speed and lose performance that way. There are jumpers on the two motherboards I used and the changes don't take affect. At first I thought it was a bad motherboard (Asus PIIB-S) took it back and got an Asus PIIB. Both seem to hold the 4.5 multipier no matter what I set the jumpers for the multiplier to. Is this really a 450mhz cpu mis-boxed as a 300 or is there some other explanation?

The 300MHz Pentium(R) II processor is not validated for
operation at 100MHz. The use of the 100MHz system bus,
regardless of the attempted multiplier, is overclocking for
that processor.

Did you get any answers to why the 300 is processing like a 450?
The 450 is supposed to be locked at a clock multiplier of 4.5 and 2 volts.
According to the Intel guick referencde guide the cpuid SL2YK is a 2 volt
66mhz cpu. I thought only PII400's and higher ran at 2 volts.
Is it OK to run the PII300 on a 100mhz bus without fear of overheating???
The store I bought the system from said it was OK.. In fact thaey charged me
$310 more than the PII300 retail box price because this cpu actually runs at
450mhz on a 100mhz bus.
Thanks for any info/assistance you can provide me with.

Hi Dan:
For all intents and purposes, you do own an Intel PII 450 but
you should not have paid any premium over a normal 300. You can pick
up a PII SL2W8 (PII 300 OEM) for around $210.00 and an SL2YK (PII 300
BOX) for around $230.00 via mail order. My SL2W8 runs at 504 and 2.0
Volts 24/7 and your SL2YK should perform similarly. Check
www.pricewatch.com, www.killerapp.com, and or www.netbuyer.com for
proof of the prices.
Go back to that store and get your money back immediately
because they just ripped you off by $310.00.
Good Luck

ripped you off! I would demand that they make it right! You are not just
some lucky guy who got a magic processor by mistake. It is has been known
for some time that the SL2YK and SL2W8 (oem) are basically deschutes core
.25 micron PII 450 with a few minor modifications.
