Help change FSB to 133
I have an sis 745 ultra board and also have an 2600xp amd and in windows and bios it reads 1900+. I have already flashed the bios to 1.6 and it still does not read correctly.
HOw can I change my fsb from 100 to 133??? is there a jumper on the mobo??
well it is the 266 version of the 2600+ not the 333. also when I try to change the fsb from 100 to 133 what key do I press?? enter wont allow changes. hmm not quite sure how to change it. I know this sounds like a stupid question but I am not at my computer at the moment.

Hi Folks,
Hey, I'm a novice, and I need a pointer.
I've got a 845Ultra, 512MB of DDR PC2100 and a 120G drive. I just upgraded to a P4 2.4G processor.
The problem is I'm stuck at 1.8G speed. Yes, I read the MSI article to bump up the FSB to 133, but it won't hold; it shuts down and resets itself to 100 on reboot. I've upgraded BIOS to the AMI v3.5 and I'm running FuzzyLogic 4 which I've also tried to use to change the FSB. That's about the extent of my expertise. Any Ideas? I appreciate any help. Please keep those answers simple for my simple mind!
Thanks,

I mentioned previously that I upgraded the BIOS to v3.5 before overclocking. I'm no wizard, but maybe that is making my system a little more stable too.
You're right on the warm reboot. My system always resets itself to 2.4g at reboot. BUT, with FL4 you simply click the "Turbo" and it's immediately back to 2.8+g. It remembers my last setting - I don't have to rerun the oc test each time which takes 2-3 minutes. Good luck!
Nope - it doesn't work for me. Are you sure you have the 2.4 that runs on the 533mhz fsb? When I run fuzzy logic 4 it completely misreads the cpu and starts overclocking at 100 * 18 rather than 133 * 18. That would be ok but it misreports the 100 as 133 so the counter starts counting up from 133 when the cpu speed is in fact based on the 100 fsb. For example, when fuzzy logic reports that my fsb is 180, it is in fact only 134 for some stupid reason and the cpu is only running at 2.42.
So I am trying to figure out how you managed 2.8 if you have the same cpu as I. I am running the latest version of Fuzzy Logic (just downloaded from MSI's live update).

MSI 645 MAX 2 - LRU P4 1.8A OC FSB 100- 133
Geetings, board users and fellow israeli moderator (does this mean u wont mod my messages? )
I am planning on buying the above mentioned board and processor. from my understanding, the best method of OCing the said combination is by raising the FSB from 100 to 133. I understand this is easily done from the BIOS, so this is not the issue here. what is the issue, however, is the change in the PCI/AGP and memory speeds as a result of changing the FSB. from what ive read here, i gather that if the FSB is at 133 exactly, the board takes care of the PCI/AGP dividers by itself so they remain 33 and 66 respectively. is this true?
one more issue i would like to discuss is the memroy speed. i have decided to buy a 333 DDR memory, and from what i understand, setting the FSB to 133 and the CPU: Dram ratio to 4:5 would result in 333 DDr speed, which is what i want. is this correct?
lastly, i would like to know whether a 2:3 ratio is possible for a PC3200 DDR or a 5:7 ratio for a PC3000 DDR (i hope my calculations are correct :D ) in 133 FSB, of course. if not, are BIOS updates which would allow such ratios due to come?
Thanks alot in advance )
Oh and i forgot to ask - i was thinking about setting the Vcore to 1.55 (3.3% increase) and the DDR voltage to 2.6 (4% increase). i understand these are minor changes that wont do any damage but rather improve my OCed system's stability. am i right on this one?
Thanks againExcellent... Youve been of great help ! :]
The only thing i dont understand is something about the memory...

PC3000 is not a standard and is not supported by any chipset, it is only usefull for overclocking.
but i AM overclocking, so how can i use a 366 DDR, for example, if i dont have the right multiplier? if more multipliers come in future bios upgrades, that would be good.
and Vgames are great, they have excellent forums in a variety of subjects... and if you like hardware hwzone.co.il IS the place for you, i hang around there occasionally too... lots of MODS and OCs and really advanced stuff (most of it too advanced for me though :( )
and as for my planned OC, it was also surprising to me but:

I've heard a few people have been able to hit 2400mhz outta the box (stock)......So I went for it! I selected the option for "2400mhz" and I didn't touch anything else, not even the cpu core voltage. The bios automatically set my memory fsb speed to 133fsb. I saved and exited and prayed it would boot up..........IT DID! It booted right up and started loading windows....So , I let it run Sisoft Sandra Cpu burn-in for about 8 hours at "high stress"...).....LOL. Ok, ok, he can hold his own ( he usually does.....bwahahhhaa)....back to the system, it was totally stable! After a 2 day uptime with WinXp using the computer constantly , in and outta games like Ra3 and MOH, I came to the conclusion that it wasn't gonna crash"

Using a SiS 645DX motherboard, we were able to easily reach the magic 2.4 GHz overclock on the standard 133/533 MHz FSB
(with no voltage changes)
-Sharkyextreme.com
and thats not mentioning many ppl in lots of forums who reported similar results...
anyway, even if i get a crappy processor that wouldnt allow me to set the FSB at 133 (and it certainly has to be crappy to not allow that) i can always go for higher voltages, up to the maximum 1.65 which isnt so risky... and EVEN if 1.65 wont be enough, there is always a chance that a bios upgrade allowing greater voltages will come out, isnt there?
i mean what could possibly happen? the mobo will shut down the computer if the processor gets too hot wont it?
but thats being extremely pessimistic... im quite sure my OC will work just fine with far less than 1.65V, and the above quotes confirm that... -
I have been trying to oc my 2200 to get the most out of it that I can. I tried the wire trick a while back but I ended up bending a pin which I fixed. After that I never oc'ed my cpu. I tried the other day just to raise my FSB but had no luck.
For some reason when I raise the FSB nothing happens to the cpu. I had the FSB at 290 but the cpu was still 1800mhz in bios, core center, and windows. Im pretty sure you can raise the FSB without unlocking the cpu. I thought I had before. Now I cant for some reason, and I dont know why.
What am I doing wrong? How come the FSB wont go up and change my cpu clock? Any suggestions?
Thanks.Hi, thanks for the tip. I changed the fsb/ddr ration to 1:1 as you suggested and upped the fsb to 140 last night (multiplier set at 7 in the bios) with Vcore left at standard. WCPUID showed a clock speed of 2100 with a multiplier of 15. The cpu temp is now around 48c, and system seems to be stable.
I will try upping it a bit more tonight, but a jump of 300 Mhz over the standard clock speed seems pretty good to me.
The only thing that is bugging me is that I can't up the multiplier from 7 in the bios, even if I go at 7.5 with a fsb of 133 the system won't boot, even when I up the Vcore to 1.8v. Also 7 is the lowest I can go (I get options from 7 to 13.5). If you know why this might be (do I need to unlock the cpu?) or have any other tips for oc'ing this system I'd be grateful.

I'm sure many of you have heard of this problem before, but please bear with me as I would greatly appreciate everyone's help in solving this problem. It is becoming very frustrating at this point as I need my computer to be working.
I read in the above posted AMD FAQ that if it is not showing correct processor speed (In my case showing 1500+ instead of 2200+) to set the FSB to 133. I went about doing this and on reboot after saving BIOS i get no signal sent to my monitor. I know this is a common cause but I don't seem to understand what's wrong. Am I supposed to set the CPU clock ratio to 13.0 or Auto in the BIOS?
If anyone can think of what can be wrong and give me input I would really appreciate it. Thanks all for your help!Srry Bas men engels is ni zo goe, dus neem me nix kwalijk.

MSI x48 cant change FSB at all
hi,
i would like to ask if anyone of you encountered problems with changing FSB on MSI x48 platinum, because I'm encountering very weird "bug", everytime i change FSB save and restart bios showing me its running on ie. 8x350 but when i boot to windows and check it in everest/vista/CPU-z/whatever its showing only 8x333 which is default, after some tries i found that if i set any value to FSB it will boot up and bios will shows what i set and in windows its still at 8x333, i tried even some insane values like 8x600 and even 8x800 without any change of voltage only DIMMs i have at 1.92, everytime its booting up with bios showing 8x600/8x800 but its obvious that running 8x800 without any change of voltage is unreal so ....are there any secret values in bios which can disable "overclocking" ? can i access them ? how ? can re-flashing bios v2.2 with v2.2 from web pages help ? if it causing bad HW, which one ? CPU ? MB ?
PS: my brother have exactly same setup as me, and he doesn't have this problem, only thing we made different is that i installed Vistas with ACPI S3 and he with S1
PS2: i have 30-35°C on CPU idle and 40-45° burn depending on ambient temperature
NB is something like 50 ?
PS3: my setup is in signature, just ask for more details if its not sufficientjust want to inform you that today bios flashing to version 2.3 solved my problem...i was finally able to overclock my PC :P

DKA790GX Platinum, have problem with changing FSB in Dual Core Center
Hello guys, freshblood is here,
I change fsb in Dual core center, but unfort. core temp and CPUZ don't reflect any changes.I agree. The BIOS gives you better control with better options.

Dumb MSI Dual Core Center. It is not the best tool ever developed. Use the BIOS for overclocking your system. -
I was having trouble sending to hotmail accounts from my Earthlink account, they had me go into Mac Mail preferences and make changes (because they claimed it was Mac Mail's fault, even though the hotmail error code said it's because Earthlink is blocked by hotmail), now Mac Mail doesn't work AT ALL - any help changing the settings back to correct Mac Mail settings? I can provide a transcript of the entire tech chat session, if that will help...
both apostrophes are used correctly, thanks
doesn't = does not (this is called a contraction)
it's = it is
Mac Mail's fault = possessive
any help with the actual issue? thanks! -

I am a hold out to an I Pad. Help change my mind! I travel and while gone, for several months at a time, have always managed my photos on my laptop on a daily basis. This means deletions, naming, filing in folders. Is this possible on an I Pad? I have just returned from a 2 month trip with several thousand photos. If I had waited to name and file these until I got home, it would be misery.
The iPad is a great device but it can't do all things. To accomplish all the tasks you mention I feel a laptop is the best tool.

Help someone tried to change FSB wont change
ok well I just got into some over clocking and I have a MSI mother Board with a 1.7ghz Celeron and I went into the bios and I was going to try to change the FSB from 100mhz to 133mz and the voltage from 1.750v to 1.850v, well I saved the changes and exited and my computer rebooted and I got a POST warning it said FSB mistake and it changed the FSB back to 100mhz and I cannot figure out how to keep it at 133mhz well my mother is this http://www.target-sale.com/tusa/items/mbsocket478/i03770.html thats even where I bought it from but I dont think they would help me with overclocking its a cheap MSI board yes but I didnt have much choice becuase I had a AMD 1ghz and the fan shut off in the middle of the night and burnt up the chip so I just replaced everything I have a ECS Board and a AMD Athlon XP 1800+ but I need to get a different board for it becuase the ECS isnt working right with it well if anyone can help me with my FSB change problem it would be appriciated, thanks

Thanks,

Josh, please try and use more punctuation. Your posts are very hard to read.
Anyway, i don't know for sure, but i think your CPU supports clock throttling. This is a mechanism that slows down the CPU if it gets to hot. You will notice it, it's quite a steep change in clockspeed.
Intel has very clear spec sheets on every single piece of hardware they aver made, you should be able to find the max temprature in those. Personally i keep a temprature of 55-60 degrees Celsius as an absolute maximum.
