Setting CPU Speed (Asus A7V133)

[That Other Guy]

A7V133 BIOS REV 1009, Athlon Thunderbird 1.33 GHz


I swapped the original 900 MHz Duron with what was supposed to be a
1.33 GHz Athlon Thunderbird.

When I ran the computer the processor showed up as a 1000 MHz Athlon.

The board is configured to be jumperless.

In the BIOS setup it gives me two choices for the CPU speed: 1000,
which is where it's at, and 1333 which is what the chip is rated at
and the speed I would like it to run. But when I set it at the higher
speed the computer blue screens during the startup process.

I know it isn't the memory because I have had the memory set at its
rated 133 for years, and if I leave the CPU and FSB at 1000 I can run
the memory at 133 no problem.

But this new Athlon will not run properly at its rated speed.

The motherboard has always been absolutely trouble free since I got
it. Same with the memory. The only new thing is the processor. Am I
safe in assuming that the processor is defective? Or is there
something else I should try?

I am concerned because I have an Athlon XP 2100+ (1.74 GHz) (now in a
different computer) that I was planning to put into this MB
eventually. I would like to determine now if the MB is the problem.

TIA for any serious replies. Those with sarcastic comments please
save them for somebody else.

From what I know of this mobo it is impossible to run the FSB and memory bus
at different speeds. Therefore, if you've been running the FSB at 100Mhz,
you've been running the memory at 100Mhz as well.

But this new Athlon will not run properly at its rated speed.

Could be your RAM, maybe the timings are set too tight.

Set the CPU frequency to "User define" and set it to 133Mhz.

Have a look at this page:
http://www.all-about-pc.de/english/Hardware/Motherboards/asus_a7v133/ASUSa7v
133_install.asp

Also, it may pay to look for an updated BIOS for it.

When I set it manually (by adjusting the multiplyer) the steps are
1000, 1400, etc. I tried 1400 but it didn't even begin to start up,
it just froze.

I already have the latest BIOS revision.

This answer tells you that the FSB *IS* set to 100.
(10x100=1000/14x100=1400)

Try setting the jumpers on your mainboard instead of relying
on the "jumperless" settings.

I have an A7V (the original non-133) with a Duron 1300 in it
(the old 13x100fsb version) and it does not like jumperless
mode. I set the jumpers manually. Refer to your manual on
how to set the jumpers and try that. Set them to 133fsb x 10
multiplier. If it doesn't POST then you know that the
multiplier is locked and the board won't let it work.

That may be the problem. From a latency standpoint it would've been
better left at synchronous 100MHz setting, and now that you have the
133MHz FSB CPU it now "needs" set to synchronous setting... that is, if
you haven't already.

You could merely assume the memory is fine but might as well TEST that
with http://www.memtest86.com

Also you were a bit vague about "bluescreen at startup".
What, exactly, was that bluescreen?
When, exactly, did it occur?
Have you tried to see where it stopped in a bootlog?
If you were to boot to DOS and do (whatever) would it stay running?

Just for the heck of it I'll ask; are you sure the heatsink is
well-seated, properly installed?


Is it staying cool enough?
Is your power supply decent, not a generic, and your voltage readings are
still the same?

Have you tried the jumpered mode?
Have you considered that if the northbridge is too hot it'll be less
stable at 133MHz FSB?

When I set it manually (by adjusting the multiplyer) the steps are
1000, 1400, etc. I tried 1400 but it didn't even begin to start up,
it just froze.

When all else fails, reset cmos to defaults and try it afterwards,
changing ONLY FSB to 133 for the time being.

I already have the latest BIOS revision.

"Sometimes" a board will run better with something other than the latest
bios. You might see if there's any archives for your board at web forums
like http://forums.amdmb.com , which bios versions have (any particular)
attributes.

I am almost certain that I had the FSB and the memory set a 133 with
the Duron.

The Duron 900 ran on a 100Mhz FSB. I honestly doubt you had it on a 133Mhz
FSB unless you unlocked the multipier and reduced it, it was *very*
difficult to get those CPUs to run at 1.2ghz (9 x 133). Are you sure that
your RAM is rated for 133Mhz? That seems to be the problem from here.

When I set it manually (by adjusting the multiplyer) the steps are

That tells me your FSB is still on 100Mhz.

No probs. As I said above, I think you're still on a 100Mhz FSB and am
inclined to think your RAM is only rated for that.

Good luck.

I guess it was only the memory that I had running at 133MHz. I never
did anything fancy with the setting of the computer. It just worked.

It is absolutely rated at 133MHz. That's what I ordered, that's how
it's labeled, that's the setting it works at. Right now the computer
is working fine at this setting:

Current CPU Speed 1000MHz
Operating Frequency Setting 1000MHz
CPU Clok Multiplier 10.0x
FSB Frequency 100MHz
DRAM Frequency 133MHz

It works fine this way. It only has problems if I change the CPU and
FSB to 133MHz. I might be wrong, but it seems to me that it isn't
likely the memory if it is running now at 133 with no problems. I am
running Memtest on it right now just to be sure. So far it hasn't
found any problems.

I assume the above numbers are from your BIOS.

Are you completely sure you have an A7V133? I have an A7V
(not 133) and I know it won't do 133 fsb because of the
limits of the chipset as it was never designed to go to
133fsb.

Your Duron IS a 1.3 as it is supposed to run at 133x10. It
is a newer one, that's all. I have a Duron running for very
small server duties here and it is a 100x13 older model.

Is there a setting to change the AGP/PCI/ISA bus speed
and/or multipliers? If so, make sure you are not
overclocking them as well.

 

[That Other Guy]

Those numbers are right from the BIOS. I played around with it some
more and got it working like this:

Current CPU Speed 1266MHz
CPU Clok Multiplier 9.5x
FSB Frequency 133MHz
DRAM Frequency 133MHz

It runs perfectly this way.

Then, just for the heck of it, I tried it like this:

Current CPU Speed 1330MHz
CPU Clok Multiplier 9.5x
FSB Frequency 140MHz
DRAM Frequency 140MHz

I didn't expect it to work, and it didn't. Crashed before it was
fully booted up. I put it back to 1266MHz as listed above. I figure
that's the best I will get out of it.

Completely.

I have an A7V
(not 133) and I know it won't do 133 fsb because of the
limits of the chipset as it was never designed to go to
133fsb.

The A7V133 is apparently a refinement or evolution of the A7V. I
think the 133 refers to the ability of the FSB. For some strange
reason that I never figured out they have it listed as a 200/266MHz
FSB. This is right on the front page of the manual which they have in
pdf format on the Asus website.

Your Duron IS a 1.3 as it is supposed to run at 133x10. It
is a newer one, that's all. I have a Duron running for very
small server duties here and it is a 100x13 older model.

My Duron is 900 MHz. It is an Athlon Thunderbird that I am trying to
run at 1.3 GHz.

Is there a setting to change the AGP/PCI/ISA bus speed
and/or multipliers? If so, make sure you are not
overclocking them as well.

The BIOS says that at FSB speeds over 120MHz the PCI bus will usually
run at 1/4 of the FSB speed, or about 33MHz for a FSB of 133MHz, a
completely safe speed AFAIK.

At this point you'd likely be best off to just return the CPU, bitching
about the situation to Directron to see if they'll give a complete refund.
You'd have a much faster system by buying a newer Athlon XP series CPU and
a motherboard for it, and memory, etc... you really weren't getting that
much of an upgrade from the Duron to the Athlon you have, even if it had
worked.

bitching about the situation

Make that, "politely complaining"

 

[Wes Newell]

I guess it was only the memory that I had running at 133MHz. I never
did anything fancy with the setting of the computer. It just worked.

Did you clear the cmos before installing the new cpu? Did you check vcore.
Should be 1.75v. Do you have a at least a 300W PSU?. Are the jumpers on
the board in default? Did you try the new cpu in your other machine? Did
you try your 2100+ in the av7133?

Yes and the fsb numbers are the marketing department at work
to entice newbies and the computer illiterate. 133DDR is
effectivly 266 because it send informaton twice for each
cycle instead of once.

My mistake. *I* am the one with the 1300 Duron that a couple
of years ago replaced my 900MHz Athlon.

Auto bus multipliers are a pain and can stop the computer
from attaining anything good for overclocking which, of
course, you are not doing so the point is mute. D

I read your other post and it seems strange to run at 133
with a 9.5 multiplier. Are the original posted settings the
default settings?

If you mean these:

Current CPU Speed 1000MHz
Operating Frequency Setting 1000MHz
CPU Clok Multiplier 10.0x
FSB Frequency 100MHz
DRAM Frequency 133MHz

They are the default settings with that chip, all except for the
memory which also defaults at 100MHz.

If I try to set the BIOS to a faster CPU speed the next (and only
other) step is 1333 or thereabouts, which also changes the FSB and
memory to 133, I guess because they are in sync. That was the setting
at which it is unstable. The only way to get an intermediate setting
is to change the multiplyer, in which case the next step down from 10
is 9.5, giving me a CPU speed of 1266MHz. It runs stable at that
speed, and, as I said before, I will leave it that way. This is just
a secondary computer that I am playing around with and right now I am
too busy to spend more time with it, especially since I won't gain
much.

U keep saying that ur memory is at 133MHz and your FSB is 100MHz.
With your FSB at 100MHz is the setting 100+33MHz enabled for your memory?
If so it will not work when u try to set your FSB to 133. 133+33 will stop
the memory from working.
Just thought i would post and ask

IMHO in KT133(a) the memory setting for 100/133 memory is independant of FSB
setting. It will not create a memory clock speed of 166 MHz.
The term FSB+33 (or FSB-33)was derived from ApolloPro 133 chicsets, IIRC,
for combinations such as FSB 66 memory 100, fsb 100 memory 66 / 133 and/or
fsb 133 memory 100
