FSB overclocking on AMD2600+

I have gon a KT4Ultra Mainboard (Bios 1.4) with a 2600+ CPU and each time i try to change the FSB with Fuzzy logic the System crashes.
Can you help me?!

At least you have to set the CPU-voltage to \"1.65V\" or \"Auto\" (here you can also use a higher value but be carefull: the more voltage the more CPU-heat)
Yes, have manual. I don't quite understand all there is in the MB BIOS. Learning though. CPU Mult is set to AUTO and is showing up as 12.5. and the Freq for FSB is 166, which is only giving me 2083MHz in BIOS. CPU Voltage is also set to Auto. I have been messing with the first two items, but did not know about the CPU Voltage. I have restarted system after chg freq and it has not come back up. I reset jumbers on board to restart it and then reconfig some settings.
Why does it not recognize the CPU at 2600 automatically????

MSI Admits to FSB Overclocking

MSI Admits to FSB Overclocking
They said in there next bios release, but maybe this is what messed us up with bios 1.3. Their cheating for the benchmarks and were getting screwwed in the end.
MSI still hasnt answered any of my emails nor have they refunded shipping costs of my 875 neo mobo that had to go back cause they killed it with bios 1.3 :O

set FSB:CPU in 5:4
increase cpu vcore with small step
increase FSB to 250,260,280.. you must testing if you put FSB to 250Mhz RAM will working at 200Mhz
set CPU interface to default(not aggresive)
thats mine thinks about that.
expert will reply hope soon to corecting me if im wrong

[AMD] FSB overclock doesn't hold after Standby???

Hello fellow overclockers,
My motherboard is a K8N Neo2 Plat. BIOS v1.8 and I just bought the board and the FSB overclock isn't holding once I bring my PC out of (S3) standby; all the other BIOS changes appear to be holding but for the FSB overclock settings!!! Did I fail to check or uncheck something in my BIOS settings which would enable my FSB overclocked settings to hold once I bring my PC out of system standby? I will note that if I restart my PC then the FSB is overclocked both in the BIOS and in Windows. Thanks in advance!!!

My advice is forget about S3 if you overclock .
Great response syar2003 thank you I just tried hibernate and when I awoke my PC out of hibernate the FSB overclock held! So I'll put my PC in hibernate instead of S3 standby for now. Hardly a hassel to us ClockGen to reset the FSB overclock once there lost due to S3 standby. For now hibernate is my choice.
Cheers!

FSB Overclocking

I have a MSI MS-6334 (815M Pro) mobo.How do I oerclock my FSB,as I do not have any option to do so through the BIOS,and the manual doesn't list all the jumper settings I found in my mobo.

then i would guess you have an oem board with overclocking disabled by the pc maker,tiny,dell etc
msi boards have this bios
http://www.msi.com.tw/program/support/bios/bos/spt_bos_detail.php?UID=88%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20&NAME=MS-6334

Is FSB overclocking above 175 MHz possible with KT4 Ultra?

I would like to squeeze a few extra MHz out of my AMD XP2600+ (without unlocking or other hardmods that cost money if they fail...). I have upped the FSB to 175 successfully, which gives me just above 2200 MHz CPU speed as reported of Motherboard Monitor. But when I go above that, it crashes. Upping the voltage from auto (1.65 on my system) does not seem to help. A guy on an overclocking board suggested that it's because it stops in the AGP/PCI slot since there is no lock of those speeds. Is this possible in any way, or are there any other dirty tricks to use so I can get more speed out of this?
Thanks a lot in advance!

thanks!!!yes, it really seems to be a power source issue...
i am using a powerline 450W power source, and the smart doctor utility form asus reported a reading of red marked warning 3.12 volts intead of 3.3 volts, also i tested the 3.3 rails using a multimeter while the system was on and capture drivers under conflict and it reported a 3.25 voltage.....i opened the power source's box and clean its dust, and so, the problem is not happening anymore!!.anyway smart doctors is reporting a 3.15 voltage instead of 3.3 (not in red or under warning message)and the multimeter is reporting 3.27. but everything is working fine: capture and tv out fetures while using the processor as an athlon 2800+ for the first time since i bought the motherboard........
the 5 volts line is reported by the multimeter with 4.95 volts after and before the problem was happening, same with smart doctor.
the hardware i used was:
-two MSI kt4 ultra boards
-kt4A
-an intel motherboard which i don't remember its brand, using dimm pc 133 memory(using anoter power supply)
-asus v8460 for all boards
-same ddr memory for all msi motherboards
since the voltage is still not 3.3 volts reported, even if the entire video card is working fine, and i only cleaned the box, and didn't change anything to its structure, maybe the problem could happen again, i guess i should buy another power source then.
i am very thankful
Andres.
PD: i see that a lot of people is having this kind of problem through the forum and maybe its due to this voltage stuff too....maybe it'd be a good idea if a sticky thread is posted repoting this stuff i believe. (if it hasn't yet of course)

KT6V-LSR 200 FSB overclock doesn't take?

I'm running the following hardware...
KT6V-LSR
2100+ 0248 T'bred B
512Mb Corsair PC3200 C2
Slapped everything together, booted up, loaded the defaults in BIOS, then immediately changed to 200x10 (which I knew my chip and memory would have no problems with) and restarted. Worked great, right out of the box!
So I wanted to find out how high I could take the FSB (to compare to my nForce2 board in my other system) and was able to get it up to 230 FSB after lowering memory timings to 2.5-3-3-6 and increase of vDIMM to 2.75
I thought this was pretty darn good considering a 233 FSB would need a 7:2:1 divider (which of course isn't available) to keep the AGP/PCI in spec. But when I ran CPUz from within Windows (also verified with the MSI Core Center) it shows my FSB stuck at 200?!?
It does display the correct multi that I have set in BIOS, but regardless of what I have set FSB to (from 200 up to 230 in 5Mhz increments) the BIOS saves the settings, POST displays the increased CPU speed, but Windows utilities show the truth... still running at 200 FSB.
I have the Dynamic overclocking disabled in BIOS since I wasn't familiar with that and would rather have manual control over my overclock anyway. As I said, I did have to reduce memory timings in order to get the board to POST once I got over 210 FSB, which leads me to believe it really is trying to run the thing at the FSB I've set. Otherwise, you'd think I could put it up to the max 280 or whatever if all it was going to do is stay at 200.
I'm using the latest BIOS release available. Anyone else encounter this strange event trying to use >200 FSB?

Have you ever checked your PCI and AGP frequencies at Sisoft sandra or another 3rd party software when fsb is set to 200 mhz.
There is a problem, this moron mainboard doesnt give standard PCI and AGP frequencies when CPU's fsb is set to 200mhz or higher.
Look in that program and you'll see that when fsb is 200mhz PCI is 41 mhz.This is a realy realy big handicap to make overclock.
This mainboard is not a good mainboard.Clear Cmos jumper's position is the worst ever that I've used lots of MOBOs.
there is no AGP/PCI divider at 200mhz or above.This moron mainboard uses AMI bios that doesnt support AMD CPU Mobile modding and using up to 24X multiplier.
-'s are
1.there is no PCI/AGP multiplier at 200 mhz
2.ClearCmos jumper's position is bad.
3.AMI Bios sucks.It must be Award Bios.
+'s are:
1.there are 3 fan sockets on mobo.
2.doesnt have any stability problems.
3.This mobo is only for standard users.
lock my spect ....sempron 2200+ @ mobile

Bios AMI not is suck ,is better max multiplo L6 in MoD mobile

Fsb overclocking...what does it actually change? (K7N2 delta-L)

Hi all,
I got my new mobo K7N2 delta-L, and I've heard some talk that it should be safe to OC fsb with this mobo as it wouldn't change any other speeds than only the speed of cpu.
So I'd like to hear how it really is, if I change the fsb does it have any impact on pci or most importantly ide devices? In bios I can set the speed of AGP and memory manually so I guess the fsb doesn't affect to them. But does it then if I don't set memory manually and set it to AUTO or SPD? Most importantly I'm asking what about the IDE, now as I understand pci speed is the same as IDE speed, and there is option in bios "AUTO detect pci clock", if I set that to enabled, does that mean that my hard drive and cd-rom speed always stays the same (33mhz) nomatter what I change my fsb? Please someone give me detailed information on how changing the fsb on K7N2 delta-L works and everything that it affects, or does it really only affect on cpu speed as I've heard. Thank you very much already!

Just from my experience upping the fsb also ups your PCI
cards, AGP video,CPU and last but not least memory.
I think the most gain is in memory benches. The CPU doesn't jump much but the memory is very noticable.
Upping too far can and will lead to a non posting computer,
the tough part after hours of experimenting is to try and play your games without addition problems.
I was O/C'd very well but had to quiet it all down to play Grand theft auto Vice city.
Had trouble with the O/C on that one alone, all else was fine with 446fsb 223x10.5 but had to wave it all good bye for the sake of the game.I like the game so near stock is what I'm running now.
I did however just upped my video card to a Radeon Pro 9800 and wait for it and hope I can reclaim some O/C but heck with that card I may not need it.

FSB Overclock, Computer shuts down after 15 sec

Hello All,
I'm putting together a computer together with the K7N2 Delta board for a friend of the family. It's a XP2800 chip, with a PNY GeForce Fx 5800, and 256 Crucial mem. Here's my prob:
The processor wasn't running at full speed so I went into BIOS, changed bus speed to 200MHz. It obviously should be set to 166MHz, which I learned later. I was successfully able to set the jumpers for the bus speed back to Safe Mode at 100MHz and then boot back into the BIOS. Now my problem is that the Motherbaord doesn't stay on more than like 30 secs without shutting off and the only way to restart it is to kill AC power to the board. At which point, start it again and the process repeats itself.
Does this mean I fried the board and CPU? I sure as hell hope not
Thanks
Lue

Ok:
Power Supply is 400W max output, it came with the case.
PNY GeForce FX5200 128MB DDR
Crucial 256 DDR2100 Ram
Standard Floppy
LG CDRW
Sony DWD+-RW
WD 120 Gig Hd
WD 40 Gig Hd
SB Audigy2 MP3
The computer WAS working with everything in it. Loaded XP pro fine, did initial driver installs. Then I went into the BIOS and set the buss to 200MHz. Then the problems start.
Now, I also checked the CPU fan cause I saw other articles were the CPU was overheating and shutting the computer down. I booted the it up and went into the PC Health in the BIOS and watched the CPU Core temp go to 45 celcius before I turned it off. Could it be the comp is overheating and shutting down?
Thanks again
Luke

Is there any way to overclock an A64 by adjusting the multiplier?

Is there any way to overclock an A64 by adjusting the multiplier?
I have an Athlon64 3200+ (Socket 754) and a MSI K8T Neo-FIS2R.
Seems to be a sweet overclocker, but my RAM cannot run at much more than the normal 200 (400) MHz, so FSB overclocking is no good for me.
/Salmoneus

hmm the a64 is locked so you cannot use a cpu multipier to have only cpu go faster..
i oc with the fsb....but noticed that i may actually be over running my power, at high oc's(233) if i unplug at least 3 hard drives, and some fans it will run microsofts memmory tester...but not with them in.
you may be able to oc if you drop your mem speed down in bios to 333 or 200.
so when you oc the memm will clib from there...i have seen good results from that.
one person was able to catch my 232 results from dropping down to 200 mem speeds.

Can't set fsb to 133mhz

I'm using a k7t turbo(ms 6330 ver.3) motherboard and i have no idea how to set fsb to 133. In the manual it shows a jumper called j17, but on my board there is no such jumper. I tried setting the clock rate through the bios, but the highest i can get is 132mhz. any help would be greatly appreciated.

Go in the BIOS to the Hardware Monitor Setup page. There are two entries that have to do with the FSB. The first one is CPU FSB CLK. You can only set this to 100 or 133. The next is CPU FSB Overclocking. This one adjust the FSB one at the time. For running at 133 FSB use the first and check if the system is stable. then if you must, overclock (or underclock).

Overclocking not showing in Windows

OK, I'm new to this forum, but not to forums in general. I've searched as best I know how and I could not find a direct answer to my problem. I did find out that Core Cell had to run at startup, but it still will not reflect the overclocking in Windows.
Am I doing anything wrong? I've found numerous threads discribing nearly every other question I've had, and thank you all for the answers, but this one stumps me.
System:
875p Neo mobo
P4 2.6c chip
1 gig Kingston Hyper-X pc3200 Ram (2x512)
1 80 gb ata133 maxtor (I know)
2 80 gb sata150 maxtor (raid on Promise)
Radeon 9800 pro 128
Audigy 6
Lite on DVD burner (dual format)
Lite on Cd burner/DVD
Overclocking is at 250mhz in Core Cell (3251 mhz), but it changes back to defaults frequently (it will not save either). SiSoft Sandra reports 203 FSB even though I have it set to 250. All setting in BIOS are from forums lpreviously listed. DOT is disabled (I do have BIOS version 1.9 if anyone wants an e-mail) and RAM is at 5:4 (333). AGP is locked and everything. Windows shows 2.6 chip running @ 2.64.
HELP!
PS: I can't get my ATA133 drive to be recognized on Promise if RAID is running. Right now it's on the ATA100 slot1 with DVD drives in slot2. That's the only reason I bought this board and not the 865p Neo2.
Thanks in advance,

Yes "SoCalMX" is for the most part correct....Windows will not recognize a FSB overclock that has not been done in the BIOS, But be carefull because using CORE-CENTER will indeed overclock the system!!! (if it is indeed working) as you can overclock using CORE-CENTER and then check with a utility such as CUPID http://www.cpuid.com and it will show a CPU increase!!....I say to be carefull because people do not see the OC in windows (or with the INTEL frequency ID) and forget that they have indeed OCed the FSB with CORE-CENTER, and they go back and up the FSB in the BIOS and now they have a double OC...And they wonder why their system has now become unstable ....So the best way to OC your system is by a BIOS adjustment....Just make sure that if you did make a change with CORE-CENTER that you go into it and hit (Default) and OK, Before you go into the BIOS to make a FSB change ...Sean REILLY875

Overclocking XP2400+ on K7N2-L

I have a K7N2-L and an XP2400+ CPU, with 2x256MB Twinmos PC3200 RAM. I bought this CPU/RAM combination as I read in several reviews that the XP2400+ was a good overclocker and the K7N2-L allowed the adjustment of CPU multipliers without modification of the CPU. So far I have managed a modest FSB overclock up to around 150MHz FSB but so far the only multiplier setting I can get the board to POSTwith is 7x. The board allows manual multiplier adjustments from 7x to 13x, (I assume the standard multiplier is 15 for the XP2400+). Do I actually have to modify the CPU to unlockk the multiplier or is there a bios setting/jumper that I am unaware of that enables unlocking? I would ideally like to get the FSB up close to 200MHz with a multiplier of between 10 and 12, mainly to take advantage of my fast memory.

Hey, sorry to disturb this talk,
i have also a k7n2g-l with amd xp 2400 and an Hac-v81 xdream,,,,
But i have supertroubles with the installation of win xp on this, is it possible to tell me wich driver you used to get it started right without graphical troubles etc...
i want to use the onboard card because my old gforce 2 wouldn't help i suppose,....
I would be very glad if i can have the driver version and are they from the MSI site or Nvidea....

and maybe in a few years i can follow your discussions

MOVED: Overclocking and RAID, do they mix???

This topic has been moved to Overclockers & Modding Corner.
Overclocking and RAID, do they mix???

What board do you have? It makes a difference in this case. For example, the Via K8T800 based boards do not have PCI/AGP locks, so raising the FSB overclocks all the other components as well, including the HDD controller, and it has been observed that for these boards, RAID arrays will become unstable at FSB settings above about 225 MHz, at most, so overclocking and RAID do not really gotogether on these boards. The nforce3 based boards, on the other hand, should have PCI/AGP locks, though I think (but I'm not sure) that you have to explicitly enable them in BIOS, and I've seen some threads questioning whether or not they actually work, so again the board might have problems with high FSB settings, although I'm pretty sure an nforce3 board would have a working lock and thus be able to overclock with a RAID array defined. Finally, if you have a nforce4 based board, it should definately have a functional lock on it, and it should handle the RAID just fine when overclocking.

Bios cpu Fsb Speed

by default this is set to 200, why is 200 the FSB, or is that multiplied by something?
also, it says it can go to 280, is this overclocking?
is it best to leave it at 200?
also, last night my computer was turning itself on???i dont have a set time to power on and there is no wake on lan option, how do i stop this from happening?

Raising the FSB = overclocking. If you take it to 280 (the standard multiplier is 10), you get 280 x 10 = 2800 = 2.8GHz. Now, if I were you I wouldn't try this "at home" unless you have a nVentiv Promethia cooling system or Vapochill, or something similar.

BIOS V1.6 Overclocking help pls!

Hi guys
I have a 875P Neo-FIS2R and since I upgraded my bios to V1.6 I have found the FSB of my P4 has been overclocked to 203Mhz from the standard 200Mhz. :(
I have also found that my graphics card has been overclocked. (A Geforce4 ti 4400 and the core is overclocked close to a Geforce4 ti 4600).
I can fix the FSB with core cell back to 200Mhz but this only lasts until the next restart. I have not found a way to fix the GPU ocing.
Btw I set the bios voltage of the AGP at 1.55V but on core cell it is always set to 1.6V when I reboot.
Has anyone else experienced this problem and does anyone know how to fix this problem or do we have to wait till the next bios is out (V1.7?)
Thanks for you help. :D

Hi ppl )
I no this is an old post but I know a few of us still have the problem of our GCs overclocked as well as our FSBs overclocked to 203Mhz by the new bios V1.6.
I have since e-mailed MSI technical support with this letter:
"Hello
I have recently purchased a 3Ghz 800Mhz FSB Pentium 4 and a MSI Neo2-FIS2R 875P motherboard. I noticed that when using core cell the FSB was automatically overclocked to 203MHz each time I loaded up. As I do not wish to overclock at the moment I turned the FSB down using the "-" button then pressed OK and then saved. Core cell would then read the correct 3Ghz (no overclocking).
However I found the P4 overclocked again after I restarted the next time. So I did the exact same with corecell and lowered the FSB to 200Mhz exactly so that it wasnt overclocked. I was sure I saved this setting with corecell and then I uninstalled core cell so it could no longer change this FSB setting.
However when I rebooted and checked the speed with the "Intel frequency ID Utility" the FSB was said to be 811Mhz so it was in fact 203Mhz again. I checked the CPU BUS CLOCK in the bios and it is set to 200Mhz. I then tried the default setting of 201Mhz with corecell with the same result after rebooting.
So basically how can I prevent this overclocking happening automatically. I have a MSI Neo2-FIS2R with a 875P chipset and bios version 1.6? I dont want to overclock because I want to keep the Intel P4 warrenty.
Another question: Does that MAT function that is available in V1.6 affect the Processor at all or only the RAM and will it void the warrenty of the P4 if run? It is currently set to SLOW."
soz for the long read but had to get everything in.
Now for the interesting part 8)
THIS IS MSI TECH SUPPORTS REPLY!!!!!:
"Dear Sir/Madam,
Thank you for contacting MSI Technical Support.
There will be tolerance difference when the softwares detect the clock.
It's normal. It won't cause reliability nor stability problem.
Please feel free to let us know if you still have any further problem.
Best regards,
MSI Technical Support"
8o 8o 8o
Is anyone else shocked 8o by this response because MSI seems to be overclocking "cheating" and are happy to say that is only a tolerance in the clock meanwhile so many other users have experienced this as well so it definately isnt a tolerance difference.
Thanks would like your views on the matter
