Xtreview Forum

Hi all ,
I've a weird problem with a E2160 and p45 rig
it just refuse any fsb more than 400 whatever i do even 401 fsb don't get it boot up
I don't have a clue why is this happened ,I tried many many combinations in the BIOS but with no luck
I 'm currently OC @3200MHz=400x8 but i'm looking to hit 3600MHz with air
here is my specs

I can't get the image appear using the image icon Don't know who's fault is this the forum or the host site

You are facing the so called FSB wall , The cpu will not boot @ higher FSB no matter how much voltage or settings .
Your cpu multiplier is 9x so why not 400x9 =3600 .
Anyway u can always try 402 -403 ... some time some FSB setting do not work out .Remember also to check your memory clock (ratio) and also u may consider bumping a bit your chipset voltage .

Most E2xxx processor has a FSB wall from 350 to 450 so u may consider your self lucky enough  ;) .

Edit i just saw the memory setting image , here are some notes :
1) according to CPU -z your memory is PC5300 = 333 Mhz and you are running it @ 400 Mhz , this can cause your overclock limit (so u have to add more Vdimm voltage)
2) 4Gb are not easy to get over 400Mhz FSB , try first if your computer will boost with 2 GB only .

Note about the image hosting , you have to use the right forum code for your image to show up ,this hosting support the most popular format and in our case u will need this code :

Ok ,first my memory is pc6400 not 5300 check the part number on kingston site or google it ,this is a cpu-z error
second,about the fsb hole 350~450 i considered it before and i went straight up to 500mhz but i know that my ram will limit me in this case and i can't unlink it or use a 5:4 ratio since i found no option to set the ratio in the bios all what i can change is cpu strap which i don't understand it well
third i wanna know what's my mobo fsb limit so that i don't go to 400x9

her is the image link

here is another try 3400 but with risky volts Vcore@1.6 also chipset@1.6 that's why temps are too high

P.s
in the last image you see that the cpu has been throttled althouh i disabled this feature from the bios ,any idea why?

Blump

Now all is clear  ;) .
For Intel based chipset , the lowest ratio is 1:1 so for 5000 FSB the lowest ratio is 500 Mhz (DDR 1000) , the 5:4 ratio will get your ram running @ 600 Mhz while your FSB is @ 500 Mhz . Only NVIDIA chipset based motherboard has the option for low 500 FSB and 400 (DDR 800).
Most P45 Motherboard can do 480FSB ++. Therefore, your motherboard is not limiting your overclock . In general Asus P5Q does from 500-520 up to 550++ (with some voltage and cooling 570-600 Mhz).

Have you checked your overclock with 2GB only ???.
so u were able to get the CPU @ 500 FSB ??? ???
According to Intel Spec your CPU will be fine with 1.5v and 61c temp , and I can say that 1.55v is pretty safe for temp lower than 60c,
Everest is far from being the best software to test for stability or to make the CPU power consumption and temp , u can use
1) Intel burin in test
2) The new OCCT which include : linpack.

Sorry for delay there was some issue with our server, and we were busy with other Xtreview teams in order to restore and to male the server operating correctly .
Please, if possible post ALL your Bios settings (CPU memory voltage ....)

And how can i do that without a digital camera? Is there is any way like software or something like the print screen button to do that? I'm using VMware workstation and tried alot but i can't capture my mobo bios

no way ;  ;D .
just write down the important bios settings

I wish but the maximum stable memory frequency i could reach was 465 with a 333 strap i guess  :'(

Not yet but what's the difference , i only use 2 memory slots not the 4 so i'm not stressing the MCH  ::)
i saw most sites benchmarking using 2x1gigs of ram so using 2x2 is the same i guess also ::)

I managed to get it captured  ;D ;) ;D here we go

and this is my current settings

hope this help
and i'm sure i can hit the 3600MHz with the help of you and this lovely forum which i apologize for not visiting repeativly due to my hard studies and limited time ,but when i need any help ,you are the first forum i consider visiting and guaranteed helpful and speedy response
TIA
P.S. Very sorry for all typos and bad eNgLiSh  ;D ;D ;D

Then this good for u . your memory can do over 400 Mhz . but this do not mean that the chipset can do it in the 1:1 ratio .
2x2Gb stress more the northbridge than 2x1GB , check most record or high frequencies benchmark , most are made with 2x1GB . 4x1Gb is completely another story.
Now write down your memory timing manually and set your tref to 64 or more .
disable ai clock twister and transaction booster .
Set your cpu voltage manually to 1.5-1.55v .
CPu GLT voltage to x.63x
Cpu PLL voltage leave it @ auto .
Dram voltage 1.9v if your memory can do 400 Mhz with 1.9v , check your memory characteristic , u can also try up to 2.1v for a short time .
FSB termination voltage to 1.4-1.3v (usually require for quad core high FSB)
NB voltage to 1.4
SB and PCI-e to SATA to auto .
load line calibration enable :(this will remove the cpu voltage vdrop very useful for stable vcore)
CPU and PCI-e speed spectrum = disabled .
CPU  and NB clock skew auto .
let me know the result were u able to do 420 FSB ?? .
If not use the same setting with the 9x multiplier and let me know how far u can go .

It doesn't boot at 8 or 9x and i just set it as you said even 401MHz doesn't and i only use 1  memory module

There is nothings wrong with your setting , in 99% this is FSB wall.

Yes this is FSB wall ;) , Use your max multiplier 9x and try to get somethings stable @ 3.5 GHz, 3.5 Ghz is pretty good for 65 nm processor with some good air cooling .
you are lucky enough my Girl friend E5200 (45nm 2.5Ghz , 2x1MB) refuse to boot over 344Mhz no matter which volt or cooling (even under cascade) , So 400Mhz As FSB wall is pretty good for those budget processors .
Enjoy what u have and try to get the max from it . ;)

So if i use 500+ FSB could it boot with the 6x multiplier assuming there is a black hole  ;D  ;D  ;D from 400 to 500MHz
what's the processor FSB wall anyway and why it is happening ????
I thought that FSB wall was the maximum FSB that your motherboard can handle. ::) ::)

FSB wall is the maximum processor FSB . Some processor Just reach a FSB limit and refuse to boot after adding 1 Mhz (Mhz) this is called  FSB WALL.
Some processor has those issues like your which is generally limited in the range 350-450 Mhz (in your case) .  FSB has no known solution except overclock via multiplier

So if i try to set it over 450 can it boot  ::)

No , this is a hardware limit even 2 v or -200c will not help this processor to boot up @ over 400 Mhz . This why I hate FSB wall ,especially with low processor multiplier .
Usually low end processor either are bad overclocker or suffer from FSB wall .
I usually highly recommend to get a budget processor but with its full potential cache , bus ... like the E8200 For core 2 Duo or Q9550 for Core 2 Quad , Moreover it is always better to get those processors after one stepping update (Old 45 NM are based on C0  , new one use E0) ,
99% of E0 E8200 or Q9550 do 4 Ghz with minimal effort , while only good C0 can reach 4 Ghz . In this case High end (E8500) Old (C0) in 70% of case do 4 Ghz and newer (E8600 , E0 , also high end dual core ) do 4.4 Ghz in over 90% of case ,
Therefore, if budget is limited.
1)wait for a new core to appear
2)Wait for new setting
3)Get a Full capability processor
4) u will be happy with the result .

Ok thanks alot for all your time ,I'd never know that myself  :o that's why i always eventually came to this site  ;)
I really found that i've no idea in the OC mania but little  :)and there are tons of questions i wanna ask about but maybe another time in another topic
again thanks alot for helping me.
You're The MAN
