L7S7A2

[TimeBandit]

I just bought a L7S7A2 MB packaged with a AMD 2500+ for my son (6yr).
When I boot the computer up it come up as an 1900+. I have read
around the internet that a few people have had this happened. The
solution to many of these inquires is to change the FSB to 166mhz. My
question is how do I do that? The FID JP1 pin settings are set to "By
CPU", these ratio or multiplier should allowed for the correct CPU
speed, I would have thought. I don't see anywhere in the Bios or pins
on the board to change the FSB. You help would be greatful.

What speed is your RAM? It may be the cause
of your problem if it isn't at least 266MHz (PC2100).

I don't own such a board, but...

In its manual, there seems to be an advanced BIOS setting for memory
frequency. Have you tried that?

Otherwise, a BIOS update might solve the issue, but I don't see a newer one
for the L7S7A2 at http://www.ecsusa.com/.

Good luck.

Hopefully this isn't the case here, but I've seen many of these systems
sold using bogus, flat out deceptive model numbers, like AMD XP 2500+
System. Note it says 2500+ system and not cpu. Pull the cooler off the cpu
and see what the part number of the cpu is. If it's a 2500+ then it will
be AXDA2500DKV4D or similar. If it's AXDA1900... or similar, well you know
the rest....
I just looked through the manual for this board and I can't find a way to
change the FSB speed. It's autodetected, no jumper or bios settings. That
sucks. Might try loading Optimal settings and saving that in bios. If you
look at the cpu, get the codes on the last line too. That will help
determine your options. A 2500+ cpu should default to 166MHz FSB if
autodetected. A 1900+ would default to 133Mhz. But a 2500+ has a default
multiplier of 11, while a 1900+ has a default of 12. So, if you have the
fids set by CPU, then I'd bet you have a 1900+ cpu, sorry. Got a link to
where you bought this?

KC,

Memory is PC2700

Don't think it was deceptive. It was a boxed cpu with AMD packaging. A
local store (Fry's) was selling it as a MB/CPU combo. Saying that I
didn't actually look at the chip to make sure it was a 2500+, I just
assumed it was before I put the heat sink and fan on it. Although I
did write done the serial number. Reading around the internet, I see
someone else have the same problem I have with the same chip. That
person was told to just change the FSB to 166. Just don't know how to
do that.

Bob,


Will try that to night. The only thing I see in the bios that I can
change would be the Auto Detect Dram Freq which is defaulted to
disable.

That's because there is no way to manually set the FSB on that board.
At least I couldn't find any in the manual. Did you try loading Optimal
settings in bios? If your dram frequency isn't 166Mhz, might try changing
the CPU/Dram Clock ratio. If none of that works, I'd look at the cpu.

Actually the manual is misleading. I found that out last night while
playing with different settings. The manual states that in the bios
the CPU freq is for display only. Not true. I was able to change it
to 166 and now I have my 2500+. Thanks to all for your time.
