As I've already told you, some 1.03 (and older) boards could have an old
vrm. You should just look at the chip...

NO. The clamp is there for some i/o signals (from the top of my head,
some of these are 2.5V with the old spec (for old p2), and 1.8V (or was
that 1.5V?) with the new spec (coppermines/tualatins). It neither
corrects the bus signal voltage (just runs out of spec, no problems),
nor the vcore - and if you really have an old vrm (unlikely), you'd need
to set the slot-t to 1.8V to work at all (not recommended for tualatins).

9150AF-08 only tells us it's *not* revision 1.04 D03. I don't know which
revision 1.03 PCBA level introduced the new VRM, you'll have to check
the chip as Roland said.

The TVC16222A voltage clamp is used to meet the Coppermine/Tualatin CMOS
I/O signal specification of 1.5V vs. 2.5V used by P2 processors. The
Slot-T does nothing to address AGTL voltages (Tualatin 1.25V,
P2/Coppermine 1.5V) or Vcore voltages. AGTL voltages can be adjusted on
the motherboard as described here:

http://tipperlinne.com/p2b-dsvtt.htm

.... but most people don't bother since the discrepancy doesn't appear to
cause problems. Tualatin processors do not last long on 1.8V Vcore
(minimum available from old VRMs).

Only *if* your board has the new VRM - check the chip!

I can email you the patched BIOS.

Ok, where is the VRM? I see two power fet's close to the slot marked
32N03. Sorry for the short post, got to run.

Between the USB/PS2 connectors and the CPU slot, adjacent to the PWR_FAN
header. I expect either:

HIP6004ACB :-( (not Tualatin capable)
HIP6004BCB :-)
HIP6004CB :-)

Jeez, this is going to be my FIFTH time attempting to get this posted.
Fisrt four three had a screwy keyboard problem, then I made the
mistake of allowing the site to time me out.

I confused the VRM and clockgen. I've got an HIP6004BCB. Core voltage
adjusts to 1.3, correct? What's a good starting voltage for a 1.3
celery?

Any ideas on doing the agtl/agtl+ compromise like you did with the
6019 on your dual?

The slot-t board has fsb adjustment. Does it take over the mobo
control? I'd like to get the 112 the mobo allows if I cannot modify
the board for the faster clock rates.

All the celery tualatin images I see online show the chip with no heat
speader. Did they have a production change at some point?

I need to know the thread pitch and size for the cpu retention
mechnism studs in the asus boards. I did not get one originally, but
need to add it.

I ordered the AMP universal SEC/SECC/SECC2 retainers. They do not fit
the slot-t card! What gives there? The card looks like it fit's
intel's SECC only mechanism:

http://support.intel.com/support/processors/sb/CS-017374.htm

but these are supposed to fit the SECC, too. Here they are:

http://www.pccables.com/07054.htm

Am I supposed to remove the top-half of the connector and let the
pressure from the "sprung" piece in the side hold it in?
Upradeware's card won't slide all the way to the board with these,
either, unless I modify (the base fits snugly around the end of the
board connector).

What craziness. Almost there... gotta go order that heatsink now.
