Setfsb LGA775

post #1 of 5
Thread Starter 
Hi all,

I hope this is the right place for my question. I have an e8500 775 LGA socket (DG33BU). My bus speed is 333mhz, fsb 1333mhz and x 9.5 multiplier @ 3.16mhz. Since I purchased this from a retailer, I do know that the BIOS is locked. However, I checked into setfsb and noticed my clock generator happened to be on the list. My question, is this a safe thing or even possible? I can change the memory mult in the bios, but I haven't a clue how to do that. I'm using ddr2 800 3gib. Memory is set to auto at the moment. CPU-Z shows: DRAM Freq 400mhz, FSB:DRAM 5:6, 5-6-6-18, 52 clocks and 2T. Don't know what that means, but I thought I would mention it. Anyway, I hope I gave enough info regarding my question and any insight would be appreciated.

Thanks in advanced,

Dirk

you can overclock , but it has a cap on the multiplier , you can OC but very limited

and about the memory , the FSB:DRAM is a ratio , the 1:1 will put the memory at 800 IF the fsb frequency is 400 , right now its 333 x 9.5 = 3.16

i dont remember the right ratio for the memory to get to 800 flat , but you need to OC to 400mhz and leave the multiplier alone , and go to the memory ratio thing and put 1:1

it will get 800

....as i remember correctly

FSB x Multiplier = CPU Speed, so you have: 333 x 9.5 = 3.16mhz
But, also FSB x Divider = Memory speed. So, if you change FSB you also change the memory speed.

No, SetFSB isn't "Safe", no overclocking is, and the less you know about what you're doing the more dangerous it is.

As far as I know there's no such thing as a "locked" BIOS. BIOSs can be password protected (ie. you need a password to access the BIOS screen), but a retail computer would never be sold with a password protected BIOS (unless they gave you the password).

I think what you mean is that the BIOS is "locked" as far as overclocking is concerned ie, there just aren't any settings in the BIOS to oerclock.That is usually the case with retail computers. Have you looked at your BIOS to see what settings are available?

Back to SetFSB.
This program takes advantage of BIOS settings (usually hidden settings) that allow the use of other (newer?) CPUs and Memory. As such it tends to make rather large overclocking steps, the smallest of which may render your computer un-bootable. The "fix" then is to do a BIOS reset. You should know how to do that before you start using SetFSB.

I have used SetFSB successfully on a number of computers with some success.

Good Luck.

PS: Just a little help for a new poster....
It's bad forum etiquette. to use vague, general subject lines like "Help", "Assistance needed" etc.. The subject should give the reader some indication of the content so that a decision to read or not read can be made.

For this post, something like LDA775 and SetFSB would be appropriate.

Thanks for the info. Yes, I did mean that I can get into my bios, just can't o.c. As far as what's in my bios, all I saw was common things-nothing allowing me to o.c. So if I understand correctly, I should leave my memory alone if I'm not going to o.c. Otherwise, I might not be able to boot up. If I do decide to o.c., I have to change the memory settings as well. Is overclocking in the bios a better way of doing it? If that's the case, then I will wait until I build a new computer with a motherboard allowing me to do this. Until then, I'll hold off using setfsb, unless I can have someone walk me through it. Being a new person to the sight, thanks bill for the suggestion to make my subject more defined. The subject was vague.

what motherboard you got , i remember that its not the bios who dictate if you can OC or not , sure there are bios that have limitations , but it got the esenssial to OC

to OC the CPU , its the FSB frequency , you got it at 333mhz , do little increasements , save the bios and boot up , and keep going till you cant boot up , if you cant , you need more volt , there are other ways arround to OC a locked CPU , like changing the multiplier but having higher frequency , its more complicated :O and i dont have a "test subject" to help you out , im working out of memories here

the memory thing , just forget about it , and focus on having a CPU stable , you can OC your memory , just dont use the FSB/DRAM ratio thing and adjust it yourself , that ratio what it does is that , whenever you OC your FSB , the DRAM will OC acordingly to the ratio you stipulated , the closer they are , the less bottleneck will occur



if you tell me the bios and motherboard you have , i could help you more smile.gif

PS .

i hope you are watercooling , it can get hot tongue.gif

Edit

ok , i did some research ... and i got some good news and some bad news .... you better sit down and hug a teddy bear or something


... you can setFSB .... but you cant change the voltage , so your OCing will be more limited now since when you put more FSB , there will be a point where the motherboard just wont start and have to reset bios

i dont think you can get the 3.6ghz to have the 800 DDR2 speed , but you can try and see if it boots , just go little increasements , 333 , 355 , 365 and so on and on , its a tedious proscess but it will help you figure out what is your cap

then , when you get to enter bios at a OC fsb , load windows and do some bench and see if its stabe , if it isnt , you need to lower the fsb frequency , and on and on till you can run benchmakrs without the PC crashing or anything like that

THEN lol , when you have the CPU nice and OCed , go to the FSB:RAM ratio thing , and put it 1:1 and see if it loads , if it doesnt ... prepare for another round of trial and error OC lol

... this is the OC way , nothing is sure untill you try it yourself , someone can have uber speeds and lower temps but that doesnt mean its going to happend to you , there are lots of variants in count here lol

my suggestion , try to find a P45 chipset motherboard (i think thats the correct one) and swap all your stuff to it , and it will OC better (the options you have will be better than the intel one you have right now)
