Fake Pentium II 450 ???

[Christophe Despeghel]

Hello,

I just received a new boxed PII 450.

It looks very suspicious : the motherboard asus p2b reports an abnormal
2.5 voltage.

Here are the markings :

B80523P450512E SL2WB 2.0V
98320310-2950 MALAY

Comments, suggestions ?

Hi Christophe,

You can check the quick reference guide for your CPU here:
http://developer.intel.com/design/pentiumII/qit/database/SL2WB.htm

It seems like your motherboard is to blame here.

Greetings, Daniel

Hi Daniel,

Three different motherboards (two asus p2b and one qdi) report an
incorrect 2.5 voltage.

Greetings,

Christophe

Hi Daniel,

My old PII 300 reports 2.8 V (it's correct).
Another PII 350 reports on the same motherboards 2.0 V.

ASUS P2B & Abit BH6 has been known to report remarked PII-400/450's Vcore at 2.5v many, many times on this forum!

since it's a boxed PII, does it come with all usual stuffs in boxed package? do they look legit?

look through the bottom opening, how are the L2 cache chips arranged? any visible patch wires (green or black)?

post the complete reports of both Intel CPUID and C't CTP2INFO may help us to help you.

best luck!

c't Pentium II Info V 1.7 (c) c't Andreas Stiller, Nov 1998

Processor Core : Pentium II, Deschutes

Attention, ctp2info can't distinguish between 400/450 MHz types
and faked 266/300 MHz with Deschutes Core!

Out of curiousity.....

Which side of the case is this on? I can't really see up into mine since
there's a plastic peice that covers most of it up. There's some small square
holes but you can't see much. I assume that the cache chips are on the same
side as the fan/heatsink, there's no way I can see anything up in there with
my chip, the holes are just too small.

"Attention, ctp2info can't distinguish between 400/450 MHz types

absolutely correct if 66mhz FSB lock is defeated on those 0652 deschutes 266/300!

two L2 chips shall be on just one side of CPU core for SL2U7 (OEM) and SL2WB (boxed)! I'm not sure about whether it exists 'two-side' L2 for PII-450 or not, however, if it does it will use a different s-spec# other than SL2U7/SL2WB because PCB revision/layout will be different too!

so far, it does not look good! but let's wait till Joseph K. can have a chance to verify the serial numbers.

best luck!

if you did own a legit PII-450 in SL2U7 (oem) or SL2WB (boxed), it should have a so-called 'extendted' T-plate, and bottom of SEC (connector side) should be completely open to the T-plate side of PCB with CPU core and L2 chips are mounted.

if it was not the case on your PII-450, you DO have something fishy to worry about!

damn, I thought so, the code on it is 98300072-0020 MALAY, the date on the
box is August 8th, (30th week) and the PII 450 wasn't even announced until
August 24th.

I haven't built my system yet, (guess I won't now!) so no CPUID or ctp2info
yet.

Hello Christophe,
The markings appear to be valid.
For no other reason than the 2.5V operation, I suggest taking the part back to
your vendor.

Cyrus,
The 450MHz Pentium(R) II processor was introduced on Aug 24th. It would have
been manufactured in the preceding weeks.

What are the complete markings from the top edge of the processor, and the
details reported by the CPUID utility?

Here's the markings on the CPU:
B80523P450512E SL2WB 2.0V
98300072-0020 MALAY

I have not had a chance to run CPUID yet but I will do so tonight. I have
looked at the casing and it does not have the extended T-plate. According to
Tom's Hardware this is the t-plate that was used on the PII 233-333.

Thanks,

Hi Cyrus,
The markings that you have provided are not consistent with the 450MHz
Pentium(R) II processor. This is a strong indication of a remarked processor.

Contact your vendor for a replacement. If they are unable or unwilling to
assist you, contact the law enforcement agencies in your area and the area of
the vendor. Contacting Better Business Bureau, or similar consumer advocacy
group, and district attorney's offices would also be a good idea. At each
office, ask for a fraud unit if available. If those offices need assistance,
they can call our support line, and request to be escalated to the
investigators.

If you purchased the processor with a credit card, contact that company to see
if the payment can be refunded.

Please reply with the name, address, phone number of your place of purchase, and
the price paid for the processor. This information will be forwarded to our
internal investigations group. Include the complete text of this message, also.
