Overclocking? Put thermal grease on the BX chipset below the

933EB
From: §tu Taylor
Pentium 933EB Slot 1 Overclocked to 1022 on a BE6 Rev 2
First things first. Make sure it will be properly cooled. Mine had problems at first with heat on a big 2 fan heatsink. The heatsink never even felt warm to touch, that was clue #1 that is was not making good contact with the cpu. I ended up placing 2 small washers on the pins that run through the cpu, that lowered the latch points for it thus making a much stronger contact with the cpu. Just a dab of thermal paste was applied to the cpu prior to attaching the heatsink (more is not better, a thin layer that won't squirt out the sides is all that's needed).
I first flashed the bios to the RV revision, then put cpu in "user defined" mode then started out with multiplier set at 7x and FSB at 133. That gave me a 931 to boot with. Ah-hah!, Windows Desktop, and loaded very nice and fast, but.... It can do better. I went back into bios and raised to FSB to 140 this time, booted as a 984. Windows loaded without a hitch, I was going to wait until morning to try the FSB at 145, but curriosity got the best of me. Once again back into the bios, raised the FSB to 145, voltage is still at 1.7 volts default. Bios reported it as 1015, but Sandra shows it as a 1022.
The benchmarks.. I really only use Sandra to test out systems and I know it's really not that great, but it tells me enough and does what I need to do, so you tech wizards that eat resistors in your salad at lunch give me a break here.
Sandra with the cpu benchmark is now measuring:
2761MIPS on the cpu dhrystone
1370 MFLOPS on the whetstone
Not too shabby... :) Gonna hold at 145 for awhile longer, happy for now. Will try 150 FSB later and send the results back to Jeff.
Good Luck,

P-III 700
From: Ken
Just so people monitoring this newsgroup don't just see problems with
the ABIT Mobo's and get scared away I would like to post a success
story.
I have successfully upgraded my old TC440HX Pentium 200 Toshiba Infinia
7200 to the BE-6-II with Bios RV. I had very few problems with the
upgrade and am overclocking the P-III 700 to 878Mz. The system is very
stable. Posted over 900 Mz but some games had problems. I disabled the
HPT controller in BIOS as I won't be taking advantage of it right now.
Spec's

Bought the BE6-II/memory/PIII 700 from <link no longer availible, sorry>
for a bundled price of $508.
I highly suggest you monitor this newsgroup for a while before you
attempt to perform an upgrade. Mine went easy because I took a couple of
weeks to monitor the newsgroup before I jumped into the upgrade.
Fan Clearance
Abit BE6-II, Sloket, and Alpha PEP66. Does it fit, while still leaving two DIMM slots free???
From: Anthony Chamberlist
Mine only left one dimm free...I switched to a "Plus" sink with a GlobalWin
fan...it works decently (ain't no Alpha though) and gives me all the dimm
slots...

Global Win VOS32 on BE6-2 Without Losing Dimms
I really like your site and I found out something which might be of
interest for you and especially for overclockers.
(Please excuse my bad english, but it's hard to describe something
technical in another language than your mother tongue.)
I've got the BE6-2 and I'm satisfied with it, but when I bought the GW
VOS32 I knew I would face some troubles with
the DIMMs.
One possibility was to assemble the fans on top of the heatsink (direction
of airflow to mobo), you can only use two of the screws for each fan (that's
enough in my experience) which is a little louder but gives the same
performance (thanks to Tilmann Steinbrecher/ heatsink guide).
Another/ better possibility I found out by chance:
I had problems to use the supporter and retention mechanism that came with
the cooler because the lowest row of the fins ( next to mobo) was still too
high to fit between the two parts of the ret. mech..
I had to press the cooler down which led to improper seat of my P III E
slot1 cpu in the slot, so I took a pliers and bent the lowest row apart
from the next row (~ 3 cm) and bent the upper 2-3 cm of each fin of that
row back towards the next row, that the upper parts of all rows were
parallel. The distance between the lowest two rows was ~2 cm then.
After that I was able to install the cpu/ cooler with the retention mech.
resulting in much better hold of the cpu/ cooler. As a concomitant the fans
were raised up and did not block any more DIMM slots ( at least on my board,
could be dependant on height of SDRAM modules).
It's a headache to install the upper part of the ret. mechanism because one
protrusion at the edge of it blocks the cpu fan cable header (you will
easily see what I mean when you try), but when you clip it off, everything
will fit perfectly.
Unfortunately I don't have a scanner nor a cam to show some pictures to
make it better understandable, but see below for stock pics.
Just to give you an idea what the VOS32 is like check out:

Tillmann Steinbrecher did not mention that the VOS32 fits all secc, secc2 and athlons.
If anybody is interested in further explanations, I will do my best to
help.
