The
Annihilator has no problem when I set the AGP bus speed to
86MHz when using the front side bus speed of 129MHz. I was
able to run every 3D game and program I had. I noticed that
the Alpha cooler still had some room to dissipate heat, so I
tried for the grand 600MHz level.
Running a
Pentium III 450MHz CPU at 600MHz is something I see more and
more people doing and me being armed with the almighty Alpha
P3125 provided by 3Dfx Cool, I was ready to join the club. I
set the front side bus speed to 133MHz and powered up my
system. After the BIOS screen for my CL GeForce, Abit
motherboard and Abit HotRod 66 have passed the OS loaded and I
was greeted by the blue screen of death. My memory was already
at CAS3 and RAS3, so the next logical step for this was to
raise my core voltage.
I used 2.2
volts just to make sure the CPU had enough power to get it
running at 600MHz. I reset the system and the same blue screen
of death. Knowing how some people have had problems with
memory placement on their Abit motherboards, I decided to mix
the RAM around into different DIMM slots to see if I could get
a combination that would work for me. I have 224MB of total
RAM in my system. This includes one 128MB modules, one 64MB
modules and one 32MB modules. All three are rated PC125.
I took out the
64MB and 32MB DIMMs and powered on the system. Oddly enough
the system was running at 600MHz stable. This was even in 3D
applications. The GeForce seems to be a lot more tolerant to
high AGP bus speeds. The weird thing about my Abit motherboard
and RAM is that when running at 600MHz, I can run with the
128MB modules or I can run at 600MHz with the 64MB and 32MB
modules, but I cannot run my system at 600MHz with all three
modules together.
When running
at 600MHz with the single 128MB of RAM, I can still use the
default core voltage of 2.0 volts and the system is completely
stable. The Alpha is still warm, but I can’t say the same
for my burning hot GeForce. The Alpha P3 125 does an awesome
job at getting me to 600MHz even though most of the trouble
lied in my Abit motherboard and my memory.
