My CPU says FSB 266, but I have FSB 333.

AMD 2800, FSB333.

How do I change in bios to correct this, I see where the 133 is set for CPU I tried to change to 166 but then a multiplyer option came up and don't know what that is suppose to be.

Also I am suppose to have memory of 2700 but I have 2 512 sticks one is 2700 and one is 2100 should I take the 2100 out.

There are two 2800+ core.....shown below.

Athlon XP 2800+ - 2083MHz (166x12.5) - 1.65v - 512KB L2 (Barton)
Athlon XP 2800+ - 2250MHz (166x13.5) - 1.65v - 256KB L2 (Thoroughbred)

They both run @ 166 (333FSB) default clock, but with different multipliers. Which 2800+ do you have and what motherboard ?

"Also I am suppose to have memory of 2700 but I have 2 512 sticks one is 2700 and one is 2100 should I take the 2100 out."

133MHz = PC2100 (DDR 266)
266MHz = PC2700 (DDR 333)

If run both DIMMs together, it will default to the lower DIMM speed out of the two, so you need to remove the PC2100 to run at your CPU/RAM in sync (333FSB/DDR333). However that drops you down to 512MB.

And on the Memory being the PC2700 and the PC2100, the lower was left over from my other motherboard, would it be better to have more MB using the mismatch or better to run in sync with only the PC2700 with the 512 mb?

Of course this is a just being curious, the settings is the main thing I want to correct.

You already have the PC2100 stick, so combine it with the PC2700 for 1GB. Granted that means taking a little performance hit, it shouldn't be that noticeable.

When I change the CPU Frequency from 133 to 166 in the Bios, it will not boot it shows unknown processor and had to remove the pin to clear the cosmo, to be able to get back into the bios, there is a Auto detect that is set at auto detect right under the cpu frequency, if I change from auto it gives me 3 choices 1:1, 4:5 2:3 am I suppose to change that too, I did to 1:1 and 4:5 and I had to clear cosmo again same problem I did not try the 2:3? can someone tell me how to change correctely.

what you need to have in the BIOS is

CPU Frequency (166)
CPU: DRAM Frequency Ratio (4:5)

Do not use AUTO.

But that is what I did and it would not boot to Windows it booted to the screen then said click Delete to go to the bios and everything just froze up, had to pull the pin out again on the cosmo thing.

Is there something else I need to change? do I have to pull the 2100 for it to read correct?

I also noticed that after I changed cpu to 166 and the auto to 4:5 the next line shows 133 MHZ in blue can't change that one.

I used cpu-z and the 2800+ is my processor

Ok I just tried it again was going to put in the 4:5 ratio, but when I changed it to 166 mhz, cpu frequency and underneeth where it said auto I tried to change that and it does not say 4.5 it says,

Auto
5:4
1:1
5:6

same problem had to remove cosmo.

Any other instructions?

Maybe the setting is in reverse.

After you change CPU Frequency to 166Mhz, for the underneath (CPU:DRAM Frequency Ratio) try 5:4, let me know what it says on the next line (the blue that you can't change).

Again DO not use AUTO.

BTW. There is a JP3 3-pin
BIOS Protect jumper on your motherboard, by default it should be set on 1-2: Disable. Make sure it is NOT set to enable (2-3: Enable).

The Bios is in protective mode, thank goodness.

I changed the CPU Frequency to 166

I changed the Auto to 5:4

The Blue line that I can't change says 133 the same as before I changed the (2) above.

I saved to cosmo and it tried to start got as far as the black screen that identifies the cpu (did say amd 2800+) before the change (2) above, now says Main processor unknown cpu type 2666MHZ I should be able to hit the Del and go back into the bios but it will not let me so I have to pull the pin and clear the cosmo again. I am at a loss, I should be able to change it.

The bios goes back to default which is 100 cpu, I change that to 133 with no problem and just leave the auto and everything is ok, but just cant get it to 166?

Let's try a process of elimination here.

Remove the PC2700 stick and leave only the PC2100 with BIOS protective mode still OFF.

Then set your:

CPU Frequency : (166)
CPU:DRAM Frequency Ratio : (4:5)
DRAM Frequency (blue line) should show 133

Do not use AUTO.

Save the changes, reboot and tell me what happens.

Did the above got black screen again, did show the same 133 in blue,

While I was in there I removed the 2100 and just put the 2700 in set the

CPU to 166
cpu dram ration 4:5
Dram frequency went to 166 but still got the black screen and unknown processor, so went back in and put the same thing but put in Auto detect and it worked but..........I went to crutial. com and did a memory check and now it says my fsb is 133?

What a mess I ran the cpu thing and cpu is correct and front side bus still says 266? am I reading something wrong here.

With the PC2700 still in there try:

CPU Frequency : (166)
CPU:DRAM Frequency Ratio : (1:1)
DRAM Frequency (blue line) should show 166

Save and reboot. I hope to continue tommorrow....but wish we don't....;-)

Ok then, try the AUTO setting. This would mean you running your memory at 133...;-(

CPU Frequency set to 133
CPU Dram Frequency Auto

Blue writing says Dram Frequency 166

Only way it works and have the pc2100 out just the pc2700 in

I guess I will have to get in contact with ECS about why I can't change the 133 to 166?

Thanks for all your help.

Really not a very good board, but that's besides the point. I had a look at the manual & copied this one portion:

"Spread Spectrum (Enabled) If you enable spread spectrum, it can significantly reduce the EMI (Electro-Magnetic Interference) generated by the system.

CPU Frequency (100) This item allows you to set the CPU frequency.

CPU: DRAM Frequency Ratio (Auto) This item controls the ratio of the CPU FSB clock and DRAM Frequency enable the CPU and DRAM to run at different frequency combination."

Here's my recommendation(s)...make sure to have the PC2700 installed ONLY:

Spread Spectrum = Disabled
CPU Frequency = 166MHz
CPU: DRAM Frequency Ratio = 1:1 (166MHz)

I will try that and post back, I have been gone all day, and I know its not the greatest board, but it was free and the board I did have which was a Gigabyte only lasted 1 1/2 years so we will see, I did read up that they have made a lot of improvements but we will see. I will post back.

Crap, that did not work had to remove the pin and put back to

Spred spectrum enabled

cpu freq 133

and Auto

Only this time when the boot screen came up, it said unrecognized cpu 26666 MEMO little different than before but same results.

Always disable Spread Spectrum...ALWAYS!

One of two things must be happening here...either you don't have a 2800+ CPU, or you don't have PC2700 RAM.

Download CPUZ & check your CPU settings...check whether it's a Barton or a Thoroughbred. Also check the Level 2 cache size, either 256k or 512k. And check the Clock Multiplier. Click on the SPD tab & look where it at SPD Timings Table...what frequencies are listed? Then post back with your findings.

Your Memory
Your computer currently has 512 MB.

The Above was copied from the left side of Crutial's Web page says I have DDR pc2700 (because I took the 2100 out of slot #2.

This is from cpuz...

And on the SPD Tab all it says is A0
Slot#1- 512 MB

On the CPUZ page where the SPD tab is, I can see where it says SPD timing table but it is all grayed out no print at all.

I will download another copy of cpuid incase its a bad download I did that yesterday but alot of information is grayed out.

I will check on the Spread Spectrum too.

OK it did not work same as above post, but when you said memory timing, I got this information off of a program called Everest.

PC 2700 DDR SDRAM (166mhz)
Module voltage SSTL2.5
memory timing 2.5 3-3-7 CL-RCD-RP-RAS

I seen the Box that this motherboard came in and it stated right on the box that it was FSB333 & that the AMD xp2800+ processor and fan was alread on it so I was pretty sure it was and I watched him install it, but the memory I had in my other board so I double checked it with Crutial Memory analyzer and it is also correct.

I also checked on AMD's web site and this Motherboard is on there recommended Motherboards for this CPU, so can't figure it out, I did email ESC about this question and how to change it? So hopefully they will answer soon how to change in the bios, I am wondering if there is a updated Bios, my bios is dated 4/2005 and there is one dated 10/2005 but it looks to be for supporting a cpu of amds 3000?

What do you think.

According to CPU-Z, you've got a mobile version of the 2800+. Unfortunately Athlon XP-M 2800+ clocks @ 133MHz (266FSB) NOT 333FSB as you've made us believe all along.

You should know what to do now, since you are aware of the CPU clock's discrepancy, the multiplier is also 16. I should have caught that error from (your) response 8, but your adamance on the 333FSB got the better part of me.

YOUR CPU's FSB is 266 NOT 333 (2800+ XP-M). Just go in there and USE the AUTO setting, don't muck with the BIOS anymore. When you are done windows should display below.

AMD Athlon XP-M, 2133 MHz (16 x 133) 2800+

I contacted ECS because as always guess you need to read fine print, he is checking, they were very nice about it, the only thing on the box that was real big 1 1/2" letters was FSB333 and AMD Athlon xp2800+ processor onboard, what would you think? no mention of AMD Athlon xp M2800+, thank you for all your help, by the way this is not ECS error but Comp USA's for misrepresenting it to me.

Well I know that, but Comp USA was suppose to put in the FSB333 and it did say that on the box, so I did not question it, they will just have to come out and put the right one in.

So they lied to me.

I do not know computers that well that is why I am posting here and the other 2 gentlemen were very patient and helpful.

Well enough of wasteing everybodys time.

You actually lucked out on the mobile 2800+, to someone like myself and some others, it is more valuable than the regular 2800+ since it is multiplier unlocked and overclockable with the right motherboard (NOT your ECS crap board).

If I was you I'd keep that CPU, and look for a cheap overclock frendlier motherboard.

My Insurance on the computer will be up in 10 months so if I can't get them to replace this one now maybe later. I will keep that in mind for a new motherboard. I thought Gigabyte MB was good but it only lasted 1 1/2 yrs so go figure? If all else fails maybe I will have trouble with this MB in 7 or 8 months and I will make them replace it.

How to damage a motherboard or cpu when lied to. Really my MB went crazy and they told me the ECS was a upgrade to my gigabyte and that I would have FSB333 instead of 266, I had a FSB266 with a true AMD Athlon XP 2600 that benchmarked the same as this one and they told me it was a upgrade because My Gigabyte MB was not available I accepted it. Even though they replaced it for free because of my insurance I took out I do not like being lied to and if you put ECS AMD xp 2800 on the Goodley, it does state onboard CPU FSB 333 and only noticed that when I ran Sisandra, and did not do that till I updated all my drivers which took a while to do.

I have the exact same setup as Pistal, right down to the mobo, and mismatched RAM, with the XP-M 2800+, If I'd see this sooner I would have informed him back at reponse 8, about the FSB. I am new to OC'ing, but understand my hardware...With CPU-Z I see that our settings are exactly identical....What type friendler board would you recommend??

Ignorance may be bliss, but it's still no excuse...Ask questions!
