Cpu fsb clock setting?

I bought a Microstar MS-6380E KT3 Ultra with an AMD Athlon XP 1800+ (1.53Ghz) 266FSB CPU -- it just got in today.
I have it all set up EXCEPT for the clock frequency. The 6380 has a default of 100mhz, up to 220. But the AMD Athlon XP 1800+ is supposed to be a 266 fsb.
I don't want to overclock my system -- am afraid to endanger my system when I really don't need the extra processing power. I just want it set the way it should be.
There's another field -- CPU Ratio/Vcore (V), w/ the following manual description for it:
The items are used to adjust the CPU clock multiplier (artion) and CPU core voltage (Vcore). The fields provide users a tool to overclock the system. WARNING: Changing CPU Ratio/Vcore could result in the instability of the system; therefore, it is NOT recommended to change the default setting for long-term usage.
I was gonna _guess_ that I set my CPU FSB Clock to 133 and input a CPU clock multiplier (ratio) of 2 (assuming I could do that). Is that the correct way to configure this AMD Athlon 1800+ to this motherboard? The 'CPU core voltage (Vcore)' descriptor is what is making me afraid of experimenting. I would really hate myself if I destroyed my new cpu and/or motherboard less than 6 hours of having received it.
Please advise.

I doubt you can set the clock multiplier to "2" - simply it isn't available. Even if it is available and u hv not unlock your CPU, adjusting the multiplier ratio has no effect at all.
The default multiplier for 1800+ is 11.5x. Multiply it by 133fsb you get 1529.50mhz, hence xp1800+ (1.53G).
Don't confuse yourself, juz follow this setting if u r not overclocking:
FSB Clock: 133
CPU Ratio: AUTO
CPU VCORE: AUTO

Confused about the 'cpu fsb clock frequency' setting, etc., in cell in bios

just got a new k8n neo2-f nforce3 board with an a64 3500+ venice chip. It is properly recognized in the bios and windows as an a64 3500+ at 2.2ghz, but I'm confused about the cell menu settings in the bios. I see a 'cpu fsb clock frequency' which was automatically set at 200mhz, but the fsb runs at 1Ghz (1000mhz), so what is the 'fsb clock frequency' if not equal to the cpu fsb? Is 200 the correct setting for that? Should I need to change any of the other settings in here? I wonder, because my 3dmark03 score only went up 200 points from the same system with a AthlonXP 2500+ chip and kt4avl mobo, which seems like a low increase to me.....

I would set that to Manual in BIOS, so that you can incremently increase the CPU speed without causing a sudden crash. Each system is different and operates within the specs of not only the CPU, but system memory and PCI-E add-ins as well. Your video card is the primary driver behgind your 3DMark scores...but you haven't listed that?!

Setting BIOS CPU FSB clock to 333

Hello everyone,
I recently acquired the K7N2-Delta ILSR (MS-6570) motherboard; nVIDIA Next GF2 400 FSB DDR. The CPU is an Athlon XP 2500 1.85 GHZ, 333 MHz.
The mainboard specs states the Socket A (Socket - 462) supports AMD Athlon XP processors @ FSB 266/333/400. I have the jumper J11 on the board set to 'short'.
With all that said, I've tried adjusting the CPU FSB Clock Frequency to 333 in the BIOS Setup Utility yet 200 is the highest option it gives. Does the CPU Interface have to be set to 'High Performance'? Other adjustments necessary?
Thanks for any feedback!

200 mhz fsb is the correct setting, DDR is just that "double data rate" so 200 x 2 = 400 mhz

CPU FSB clock

I don't know much of computers and i have just bought an Athlon XP 2000+ processor. What BIOS settings do i have to change to make it work at the correct operating speed?
I've anyone could help me, i don't wanto fry my PC.
AMD says it's 266 for the CPU FSB clock it this correct?
thanks
Montana

Welcome
It may be set up correctly now. What speed is your chip running now - about 1667 MHZ. How is chip IDed at startup - XP2000+? If not, say you have 2000+ Tbred, set FSB to 133 (266 DDR) and multiplier to 12.5 (think that's correct default). Be sure to give your motherboard manual a good read! Will help with settings.
Depending on your motherboard model, memory, cooling etc, you may (with some experience) be able to run that chip to 166-200 FSB. But don't try above 133 FSB without proper research. You can damage your system. You'll have to furnish your system details to get a better handle on its potential.

Annoying problem that happens when cpu fsb is set to 133

Hi, i have a real annoing problem wich occurs when i set my fsb on my spu to 133(which it is supposet to be set on). It's a while now since i bought my computer. i can start of with the specs before I go any deeper now.
i use:
Motherbord MSI KT4 Ultra
CPU AMD athlon xp 2400 2.0 ghz
Gainward Geforce 4 4600
and 256 ddr ram
as i said when the fsb on the cpu is set to 133 it wont get in to the os, it just reboots itself when the winxp load menu comes up. however if i set the fsb down to 100 everything works (besides that i now am running at 1.8 ghz or something)
now the thing is when i bought it i had no use for 2.0 ghz when i bouth it so i dint care much and learned to live wih it but now games requires more power and so i want what i payed for, but the problem still stands i cant use optmal power due to this.. anyone have a clue of what i can do to fix this, is it a physical hardware malfunction, or can i fix this?
please please respond..

hm, im not that good in technical terms in english, what do you mean?
that my power supply isnt up for the job, that it could be my ram and i have not to good cooling?
as for the cooling i bought what was supported for my cpu.. it might be the power supply, i have had problems with power supply earlier but i bought a brand new one. the RAM i have no idea on..

694D Dead? Changed CPU Host Clock

Hello all,
This board was running great. I had to do a new OS install and started playing in the BIOS to overclock it. I wanted to change the CPU multiplier but did something with the CPU Host Clock setting. After I changed it the board, just died. It turns on, but the 4 LEDs are RED. I had two PIII 800 w/1GB RAM
I've done the following:
1. Pulled the board and installed one memory stick, one CPU and Video
2. Tried different CPUs (confirmed old CPUs are working fine in a Gigabyte board)
3. Cleared the CMOS by shorting the "Clear CMOS" jumper serveral times.
Any thoughts? I saw this in a earlier post - http://www.flashbios.org/
Thanks!
NB

Sorry I wasn't more complete:
I removed the battery, flipped the Clear CMOS jumper to clear the CMOS and removed all power sources, removed everything (CPU, Cards, etc)
I let it sit for a few days.
I then but the battery back, flipped the jumper so it would boot, added just memory, 1 cpu, and a video card.
Same results.
Thanks for helping out!
NB

Cannot set the CPU's FSB clock to 133 anymore. What's wrong ?

My AMD Athlon 2200+ processor runs now only on dafault value (100Mhz x 133 = 1350 MHz) instead of 1850 Mhz it just to run.
If I change the values in Bios to what they used to be (133 x 13,5 = 1850 MHz) the computer blank, monitor is black and the PC doesn't response to power button. I can revive the PC by removing and replacing the motherboard's CMOS jumper, but the clock speed stays on that 'underclocked' value.
Motherboard is MSI KT4V with 'Fuzzy Logic' -program. I've tried to set the FSB clock value back to normal (1850 Mhz) with this Fuzzy Logic by rising the value from 100 upwards, but when the program gets to somewhere around 110 Mhz the whole system crashes. Windows's blue screen can be seen with the text 'Unexpected kernel trap'.
So, something is wrong here, but I can not figure out by myself what it is. Can anyone help me ?

Yes I agree with with Wonkanoby the power supply is the culprit as usual. The forum should have an opening page telling people to check their power supply is powerful enough before posting, the amount of power supply related problems I've read myself alone is massive.
Get a nice 420 - 450W PSU with at least 24A on the +12V rail if not more. Tagan, Antec, Enermax and OCZ power supplies are the best brands.

Diamond Plus; Cell Menu CPU FSB Set at 250 x11 but Board Running 200.9 x14

I have FSB set at 250 with the CPU multiplier set at x11. Memory is set at an FSB / DRAM ratio of 1:1. The memory modules are in slots 1 and 2 (green / purple). While in the BIOS Cell Menu it is reporting Memory frequency at DDR500 and the CPU at a slight underclock. This agrees with the above settings. However, in BIOS / Standard CMOS Features / CPU Configuration, it shows the CPU running at 2816Mhz with a multiplier of x14. This is equal to the settings (200.9 x14) that are applied when "Load Optimized Defaults" is loaded and saved. All of the settings in the rest of BIOS setup are definitely set to Manual and the setting values as noted in the first sentence.
CPUZ is also reporting a FSB of 200 with a multiplier of x14. It's showing the memory as PC3200 and running at DDR400 which makes sense if FSB is really running at 200. Long story short, it's reporting everything at the stock settings as set by "Load Optimized Defaults". It is correctly showing the memory in dual channel and the command address rate at 1T. This is the latest version of CPUZ. I had an older version saved on CD. I tried this old version and it reported the same thing.
I have all of the dynamic overclocking options, wakeup options, cool n' quiet and automatic fan speed controls (except northbridge) disabled. If there's any other options that could throttle down the CPU I sure couldn't find them. Even if there were, my CPU is running atb 39C at idle so it shouldn't kick in any thermal throttling. When I flashed to the version 1.19 BIOS version at MSI Tech Support's direction to solve the "phantom modem" issue, I took the extreme route to clearing CMOS; powered down, removed or disconnected all the components, pressed the clear CMOS button, removed the battery for 30 minutes, pressed the clear CMOS button again, reinserted the battery, pressed the clear CMOS button yet again, reinstalled / reconnected the minimum required components, flashed the BIOS, cleared CMOS again, cleared nvram, loaded optimized defaults and saved, manually adjusted all the settings, reinstalled / reconnected the remaining components.
I'm at a loss to explain this. MSI Tech Support says they can't help me because this involves overclocking and they're not allowed to provide advice.
Anyone have any ideas as to what could be causing this?
Thanks in advance for any help provided.

I've been experimenting with different combinations of FSB / Multipliers / Memory dividers. My best performance is with the CPU at 250 x12 for 3.0 GHz, and memory still at 3-3-2-8, 1:1 and 1T. This is all at stock voltages and I'm not willing to risk frying anything by raising it even a little bit. It's running fast, smooth and cool. That's all I'm looking for so that's as far as I'm going to take it.

I'm getting the same anomaly with the value for CPU Fan. That's the chipset fan speed for sure. It matches the BIOS reading and it's the only fan I have plugged into the mainboard. Everything else is running from a rheobus.
The NB temp on this mainboard is really exceptional. The NB on my old DFI SLI-DR routinely ran in the 48-49C range. I guess the MSI cooling solution is pretty efficient. One other thing though, I'm using Arctic Silencers on both of my graphics boards. The intake fan on the "slave" board is directly above one of the chipsets. That may be drawing an additional bit of heat off of the chipset.
As far as the voltage values, I'm getting the same skew with a different mainboard, BIOS and PSU so this looks like an Everest issue.
IMHO, if your machine isn't doing flakey things that can't be attributed to anything else then your PSU is adequate. If you do go with the Diamond Plus and SLI, I would suggest upgrading the PSU. It seems that the 1 kilowatt PSU's are all the rage now but in reality 700W is more than adequate. Adjustable potentiometers must be nice if you know what you're doing with them. I don't so I don't bother looking for that feature.
Hope this is helpful or at least of some interest.

Can't set fsb clock (k7t266 pro )

Hi there,
I hope someone of you gurus is able and wanting to shed some light on my problem:
I replaced the duron 700 on my k7t266 pro with a xp2000+
(palomino). When I want to change the fsb clock in the bios
I can't. It stays 100Mhz
I upgraded the bios with ver 1.90, and disabled bios prot.
What is it that I'm doing wrong?
TIA

should i try a lower version of the bios?
In the bios setup menu i don't have the possibility to load
high-performance settings ( that option isn't there).
But maybe that is correct in ver 1.90
thanx

845 Ultra ARU CPU FSB Ratios?

The bios provides DRAM Frequencies of 200, 266 and Auto. Given a FSB of 100, that means the ratio of CPU:FSB is 1:1 and 3:4. (What is 'Auto')
If I run the FSB at 133, are these ratios preserved, or does some other ratio come into effect. If I choose FSB of 133 and DRAM Frequency of 266, will I be running at 354 DDR? If so, do you think a stick of Corsair PC2700 (333 DDR) will O/C to that level?

If I recall correctly, once you reach a front-side-bus of 123 MHz, the ratio sticks at 1:1. So at a fsb higher than 123, the memory ratio will ALWAYS be 1:1 no matter what you set it at. X( You are correct on your ratio assumptions, but at 123 MHz the memory ratios become useless. The Auto option is as it suggests. The BIOS will automatically set all the RAM timings per what the chips are rated at. So if you have the memory set to Auto, you won't be able to change the CAS timings and the other various memory options.
The lack of memory ratios on this particular board is what really hurts it. I've got my 1.8A P4 overclocked to 2.52 GHz on a 140 MHz fsb. However, the CPU is being choked to death by a memory bandwidth of only 2.0 GB/s. If there were more memory ratios than the one 1:1 ratio that MSI gives us, I'm sure I could improve my system's performance quite a bit. The other problem with the MSI board, that affects me at least, is that the temperature sensor seems to be out of whack. PC Alert III and MBM5 say that my CPU is at 67-68 degrees Celsius under a full load. With the case open and my hand right on the heatsink during that full load, I can tell you that the reported temperature is at least ten degrees off. If it were really 68C, I would not be able to keep my hand on it without it feeling really warm.
So those are the only two things about the 845 Ultra-ARU that make me really wish I had gotten a different motherboard. :(
Hi jdurg.
I just found a post on Usenet that was very interesting. The poster has an 845 Ultra ARU. Here's the quote:
All this time I used fuzzylogic 4 to overclock my 1.6a to 2.1 @ 133. now I
actually went into BIOS and adjusted my memory settings. This is what I did:
Changed....
DDR Frequency: from 266 to AUTO
Configure DRAM Timing by: from MANUAL to SPD
What I noticed was the CAS# LATENCY changed from 2.5 to 2 (I didn't adjust)
Now I use a program called CPU-Z to get information on the CPU, MB, and MEM.
speeds. Before the changes on the motherboard/CPU speed was normal like:
Before: (with out bios changes)
CPU Frequency: 2119.1 MHz
Clock Multiplier: x 16.0
FSB Frequency: 132.4 MHz
MEM Frequency: 351.4 MHz
before I had problems of computer freezing after a few hours.
Now: (after bios changes)
CPU Frequency: 2119.1 MHz
Clock Multiplier: x 16.0
FSB Frequency: 132.4 MHz
MEM Frequency: 264.9 MHz
also CAS# L: 2clocks, RAS# to CAS# Delay: 2clocks, RAS# Precharge: 2clocks
and Cycle time: 5clocks.
now my main question is how come the MEM Freq. has changed/decreased?
and my system is very stable now (no crashes). is this normal? I have a
no-name, cheap(only paid $60 can.) is this normal for this mem chips?
There was no reply to the message, but it looks like he was getting a 3:4 memory speed ratio with the FSB at 133. This is good! He had DRAM Frequency set to 266 and memory timings set to Manual. Using AUTO and SPD brought his memory back to a 1:1 ratio. My board won't be in until the end of the week... is there anyway you could verify this on your board?

K7N2 NoPost after misadjusting FSB clock too high

I have set up a system as descibed and it worked fine. Load OS and used it for many days. Then my son decided to look at BIOS set up and adjusted the FSB clock to something above 200MHz (he couldn't remember how high). RAM is PC333, so the setup I had used FSB at 167 Mhz as recommended.
Now the system won't POST. No beep, no video, no floppy disk activity. Tried resetting BIOS by jumper and removing battery (all power cords disconnected as well). No success. Any other ideas what to try? I don't have any other spare components to swap as a test.

I've reviewed other threads and read that resetting BIOS does NOT reset the FSB clock. Since I don't have a J10 to set to SAFE mode, seems like I am screwed. I have cleared BIOS using jumper and removing battery (with power cord disconnected). No success.
I have sent a request to MSI for support. Do you think they will be helpful?

How do I change CPU FSB Freq on 975X Platinum Pue

Hi all!
I´m thinking about overclocking my CPU and that will be my first time ever. So I am a complete noob in this matter.
I have already read the sticky "975x Platinum Pue Overclocking Guide" (I do have that board) and will have it for reference later.
1. I have one question regarding changing CPU FSB frequency. I´m asked to key in a DEC number. But how should I do it. The guide says to "Start from 266 fsb increase by 3 fsb". So do I have to put in 269 to begin with, or how else do I change the number.
2. One other thing I want to ask of before I begin. My memory is Corsair XMS2 2x1GB 800MHz PC2-6400 CL5 in Dual channel. But in Bios it says 667MHz and voltage 1.8. Do I need to adjust memory clock ratio and the voltage before I begin overclocking?
3. My third question is: if overclocking Core 2 Duo E6400 to about 3.2GHz could I face some stability issue in regard to my PSU of 410W? (that my PSU could influence the system stability in a negative way). My system is very stable I think and the PSU fan is very quiet.
4. I´m using the the most recent Speedfan and it shows unusually high cpu temps, about 100c which is wrong as I´m using hardware temperature monitor which says about 35c idle and the BIOS says about the same. Which software cpu temp monitor would you recommend?

Speedfan is no good for Core2 Duo + 975xPUE, use CoreTemp
To change your FSB, simply put in a new number. The multiplier is locked on this board still I believe, so to calculate the frequency you'll get, just multiply the FSB by 9 and that should give it to you. So, yes, that means do 269, stress test, then 272, stress test, etc. BUT, the 266 they used in that guide is from an E6600, you don't have that. You want to start from whatever it is as default.
The reason you go up by 3 is because of stability issues as far as voltage is concerned. That is to say, go up by three, stress test (i like to use 2 instances of Folding@Home) and if it crashes, raise the voltage a little.
Make your fsb:memory ratio 1:1 always, and that means it will run a little slower than what it's rated at to begin with but then you can move up from there. As a beginner doing a pretty small overclock, you shouldn't worry about RAM. At 3.2GHz your RAM will be running at 712MHz, which is a little slower, but once you get more experienced that means you'll be able to tighten the timings.
Good luck and be safe

Question about CPU FSB and K7N2-L

This is probably a nub question, but here goes anyway:
I currently have an 1800 XP Palomino processor which supports 266mhz fsb. I just installed this board with this processor and left all the jumpers at default. After reading the manual it says I should short jumper J11 (133/166mhz) on the mobo, and make the appropriate settings in the bios to achieve 266mhz for the cpu fsb. Now, I know it says this in the manual, but I thought I'd better make sure that this is the right procedure before I go ahead and do it so I don't screw anything up.
If anyone could help me out on this it would be greatly appreciated.
TIA

Cheers... it's interesting how many people make that mobo/RAM choice. I use a K7N2G-L with Crucial PC2700 DDR (2x256) and it works fine. Kudos on reading the manual, frequently it has the answers you're looking for. You're correct... make sure J10 (FSB Mode Jumper-133MHz position) and J11 (FSB Frequency Jumper-133/166 position) are set correctly, BIOS settings on the "Advanced Chipset Features" page are correct for your processor/RAM, and you should be all set. There is a good article on driver loading order (by liquidsoul) on the http://www.amdforums.com site... look under "MSI Motherboards".
