My AMD Athlon XP Barton CPU was running at 1.83 GHz, and I was using single chip of 256 MB 400 MHz DDRRAM, which wasn't enough for San Andreas, so I managed to get 2x512 MB 400 MHz DDRRAM chips. My motherboard has only 2 RAM slots, so I took the 256MB out, and plugged in both 512MB ones. Everything is working, but the CPU now is running at 1.09 GHz! In the BIOS, there's no option to change CPU's clock frequency! My motherboard is NVidia nForce, but I can't find out any model info. Any hope to kick the clock speed back to it's heights?

Have you tried placing the old stick of RAM back to see if it's still underclocked?

[Wolf68k]

Which one exactly do you have?
What are you using to read the speed?
What mobo is it, make and model?

Confused: first you says it's running at 1.83Ghz then you say it's 1.09Ghz so which is it?

[Exxon]

His standard clock speed is 1.83 GHz and with the new RAM it's 1.09 GHz

[Wolf68k]

Use Speccy to get the mobo make and model. You can also look at the mobo itself and find that, however where each of those are varies from mobo to mobo.
My other suggestion would be to first try going into the BIOS and tell it reset to default settings or....
Shut down. Unplug the power cord. Take out the CMOS battery. If possible look for a set of jumpers on the mobo labeled CMOS; either move to jumper from one set of pins to other, count to ten then move the jumper back or if there is only 2 pins with no jumper then get a jumper to bridge the pins you can use a metal paper clip for this as well or wrap a wire around one and touch the other end to the other pin. Then replace the CMOS battery. Reconnect the power cord. Turn the system back on.
If you want to make sure that either one of these reset features are working correctly. Find a setting in the BIOS you don't care about and you know won't hurt anything, like for instance setting the first boot item to but a USB option or if you're using the onboard audio then disable it in the BIOS. Restart to make sure your chance(s) take effect then to the BIOS reset and check for those things going back to their default setting.

Ok, I got the Speccy, it's saying that my mobo is NVidia nForce with nForce2 400 chipset and nForce2 MCP southbridge, revision A4. My BIOS is Phoenix Technologies BIOS, version 6.00PG.
I will update as soon as I will try methods Wolf68k mentioned.

UPDATE : Tried to set CPU to the Turbo mode through BIOS. No effect.

Looks like the bios has reset the CPU to the lowest setting available. Go to bios and look for CPU clock speed or something like that and change that to the correct CPU clock speed.
Some bios will look at CPU models numbers instead of CPU clock speed. If that is how your bios is, change that to
model number for your CPU.
Selected old boards will let you set the CPU clock speed diretly on the motherboard via jumpers or dipswitches to prevent this from happening.

What's your motherboard model?

Take a screen shot of the Speccy on the Summary page and post it

HUGE thanks to Wolf68k for pointing out what I was too dumb to notice. Selecting the Load Optimized defaults option rolled the clock speed back to 1.83 GHz. I also checked what parameters have been changed, and the one that controls CPU freq, is called FSB Frequency. Surprisingly, seems that this CPU can run @~2.00 GHz without overclocking! Again, HUGE thanx to Wolf68k! Keep howling!

P.S. if someone has mobo and CPU similar to mine, this might help:
________________
|___ Frequency ___|
|__ FSB__|__CPU__|
|_100Mhz|1,09Ghz_|
|_133Mhz|1,46Ghz_|
|_166Mhz|1,83Ghz_|
|200Mhz|~2,00Ghz*|

*I haven't tested this mode yet.

At my earlier topic, I posted this:

Now, I tried to boot it @2.00 GHz, bet it froze at mobo logo screen, so I disconnected the power cable and took out the CMOS battery for the night.
Now, the PC has went crazy. When it's turned on, it doesn't send any signal to the display, and simply keeps beeping. The HDD LED shows no HDD activity. How to fix this?

Ok so basically some how your FSB was set wrong. What the FSB is, yes, will set the speed of the CPU.
You seem to have an AMD XP 2900+? Other wise there are 2 different 2800+'s one runs at 2083Mhz the other at 2133Mhz.
I had a 3200+ which ran at 2.2Ghz.

Speccy shows my CPU as 2500+ one. I am really interested in booting it with 200Mhz FSB, however, it' s not working at this setting.

How many times did your computer beep, were they long beeps or short beeps?
The processor you have, AMD Athlon XP 2500+ has two models, the other 2500+ being a bit faster at 1.86GHz are found in OEMs.
For the one you have running at 1.83GHz, then its specifications are as follows:

AMD Athlon XP 2500+/1833MHz (1.83GHz)/333FSB/11x multiplier
To get the stock clock of 1.83GHz, take the FSB and divide it by 2 as the FSB for this board is double data rate. Then multiple that FSB with the cpu multipler to get the CPU clock speed.
333 / 2 = 166
166 x 11 = 1826MHz or close to 1833MHz (1833MHz /166 = 11...)

Setting the FSB at 200MHz, what you actually done is run the FSB at 400MHz (200 x 2 = 400FSB)
200FSB x 11 = 2200MHz
2200MHz - 1833MHz = 367MHz overclock!
If you were to run the FSB at 200MHz, then actualy FSB is only 100MHz (100x2 = 200FSB)
100 x 11 = 1100MHz

Without a good CPU cooler, there is a chance you may have damage your CPU by overclocking it way too much.
If you're actually trying to target a CPU clock of 2000MHz (2GHz), (if bios support for overclocking FSB in +1MHz increments) then
182MHz FSB x 11 = 2002MHz (2GHz)

Was your old stick installed when the problem happened? If no, remove new piece and put back the old one and see if you can get the screen back.

This is also why I asked for a screenshot of Speccy.
Just press ALT+PrintScreen and it'll take a screenshot of only the front most window then you paste that into Paint. Save it. Upload it. Post it.

[winme05]

The PC's working now, I simply want to run it at higher speed than the 1.83 GHz.
BIOS shows these FSB freq options : 100 MHz, 133MHz, 166MHz, 200MHz.
My PC's not working when I set FSB freq at the ''200MHz'' setting.
I think my cooler's good enough - together with the fresh Xilence thermal grease, Speccy shows the system temperature being 46C°.
And OK, a screenie of Speccy:

[Wolf68k]

Set the FSB to 166 which is where it should be for that CPU.
Where does Speccy show that your CPU is a 2500+? Under the CPU tab?


And just wow on the motherboard results. It really doesn't say who the maker or model number is. That's odd.
What about when you click on the Motherboard tab (for lack of a better term) on the left?

No optical drive? You have no CD or DVD drive? Odd.



Try CPU-Z http://www.cpuid.com/softwares/cpu-z.html
Maybe it's Motherboard tab will be more useful as well as show the right CPU.

[winme05]

I'm already at 166Mhz setting, now I want to use the 200mhz setting, but that one causes the PC not to work.
Yes, Speccy shows 2500+ under CPU tab.

Mobo tab doesn't give me anything better:


I have no idea why Speccy doesn't show up my DvD reader.

I already have CPU-Z, and it's no better:

[Wolf68k]

You not getting it. That CPU is meant to run with a FSB of 166Mhz not 200Mhz. It's possible that the RAM is also meant to run at 166Mhz as well. So by setting the FSB to 200Mhz you're overclocking the CPU and the RAM.

Ok that's odd about the mobo and so little information every where else. I guess the only way you'll know who made the mobo and the model is too look at the board itself.

Also, for some reason the images didn't load. I fixed part of your tag problem, you were missing the end tags to the first set of colors and what not. Try using tinypic.com, which yes I know is annoying now that they have a captcha before you can upload.

[Slamman]

An older Athlon XP Socket A?! You won't get uber gaming performance out of, but a swap to better RAM and CPU is possible.
The heat sinks aren't all that custom in terms of options for those boards, are they?
I've never had one with problems though, but perhaps consider getting a NOS Abit board, they were very good until the company closed it's doors

[winme05]

Ok, I found that my mobo is a Biostar M7NCD non-pro. Other people around the web say their AMD Athlons run fine on this mobo even with FSB at 200Mhz setting.
