Unable to overclock pentium d e2140(doesnt go over 1.8Ghz)

With your power supply it could be that you are running out of power to achieve the boot, what are your amps on the 12v? Overclocking the CPU can increase the pull by more than you think.

is says on the power sup: +12v2- - -16.0A(Yel/Black),+5vsd- - -5.2A(purp),-12v- - -0.3A(Blue)
p.s there are more lines writen on it if you'l need them just tell me i will write it down

What is the total Watts over the 2 12v rails. See you have a lot of amps on the rails, maybe this is not it. But the total continuous power may be too low.

You will see

12v1 16A | 12v2 16A

Total Power

XXX Watts

Give me those and I can probably answer you

300W Max

just a FYI,
that board has Intel® 946GZ + ICH7 chipset i am not sure how stable that is with overclocking like a P45/35 or X38/48 board.

sorry but what is FYI? and what do u mean saying: ''i am not sure how stable that is with overclocking like a P45/35 or X38/48 board.'' what is P45/35 or X38/48 board????

Well I think your PSU is good enough for an overclock, have you tried a mild overclock on auto voltage settings to 1.85 ghz etc?

What are you changing for your overclock, you can try using a Multiplier of 4.5 and a bus speed of 400 to acheive your 1.8ghz. Providing that works increase to a multiplier of 4.6 > 4.7 > 4.8 > 4.9 > 5.

Edit: looniam could be right, asus does have a new bios version for your board related to the chip. It doesn't say anything about overclocking but does mention temperature readings which could be a reason for the no boot senario: http://support.asus.com/cpusupport/detail.aspx?SLanguag...

No offence but you need to brush up on some VERY basic computer knowledge before you try something like overclocking. Overclocking is for people with advanced computer skills.

And FYI google is your friend.

For Your Information

some motherboard socket 775 chipsets overclock better than others. the P35 or P45 and X38 or X48 chipsets were extremely good for overclocking; you would be able to be a higher overclock with the same CPU then you would with a G41 chipset.

now i realize that i had been comparing apples to oranges. as the chipsets i refereed to are more for the core2duos whereas you have a pentium D. however since it does have an integrated graphics controller, like the G41, i would suspect it might not be the best board to expect a high overclock with that cpu.

That's not a Pentium D, it's a Pentium Dual-Core (Conroe-based). They never shipped a Pentium D with a clock speed that low.

thanks for that. i skipped the whole P 4&D chips . . . at least thats my story and i am sticking to it.

um actually i have knowledge about pc but i also have limited knowledge about Mb's so i am not very familiar with those chips the other thing is that i first thought of high temp. cuz my thermal grease was very old and didnt done its job properly so the temp'sn were abou 70C but i changed it today and now its 40C under full load. but i can't get over 247*8=1.97Ghz and it doesn't matter how much i raise the voltage... its still very unstable on 1.97ghz even with high voltage 1.4500V(1.3650V stock) so now im running 1.92ghz with voltage of 1.400V just in case.. but i still dont understand why cant i overclock it more that 1.97Ghz can anyone help me PLEASE! this is the only computer i got and i dont have alot of money for a new cpu or pc so it would be nice to have it atleast running on 2.6Ghz stable so i could play some games on it. Thank You,
J.K.

You don't really need expert knowledge to overclock, infact it's good to try it. As long as you keep the voltages sensible you cannot do much harm.

soo,why can't i overclock my pentium?

As a previous poster said you could have a poor chipset to overclock. There's a thing called the silicon lottery which basically means that you can get poorer performing chips that do not overclock very high. Chips are only designed to work at a validated clock speed, more than the clock speed is never gaurenteed and sometimes impossible unfortunately.

I have seen those chips clock to 3.2ghz in the past, perhaps someone with knowledge of the chip can help further.

soo i need to go find a man that makes this chip? or has high experience with it?
Were do i find something like that?!

i suspect it seems your motherboard is limiting your ability to overclock. i am surprised you cannot get past 247 on your FSB since your motherboard should support 266 with the CPUs (1066) listed that it supports:
http://www.asus.com/Motherboards/Intel_Socket_775/P5BMX...

do you know what number bios version you have?
do you believe you can update the bios w/o bricking (fubar) the board?

(please do not update the bios IF you think you can screw up the board)

Your problem is the board, the chipset that being the intel 945 doesn't handle high clocks very well and is crap even for a netburst celeron lol. Really that chipset struggles to reach 266/300mhz for higher end chips while it also runs extremely hot. I would replace the board and you can do so without having to reinstall the os provided that you used a different board with an intel chipset. Second the power vrm for this board also looks very very weak and may also be one more reason why you can't overclock your cpu very well.

A rebuild with a new board will go far.

i recently updated the bios to the newest version didnt help

i dont have the money to replace the board and if i would be doing so i would probably change to lga1115 socket i actualy already got one in mind (fatal1ty-p67-professional)
i recently found it for less than half a price that it cost slightly used so i am thinking of upgrading soon. any way the second option is to upgrade a cpu to quad core or something soo it would be cheeper but i still havent descited yet cuz now i'm thinking of geting 3gb's of ram atleast that's what i could do.

ok atleast your thinking about NOT putting money on old tech.i
BUT since your having a problem with a FSB of 247 and a quad is 266 you might end up with an unusable cpu. that intel 945 seems to be a POS if you are going to drop on more cent on that rig, look for a CHEAP (under $30)G41 chipset. the P35/45 and X38/48 are rare anymore. you would get better results with a G41 than what your doing now.

i didin't even knew that you can change the chip lol next week i will get about 200$ and then i will go to my local computer dealer to see what's what soo could u write down the best chip model for me that i should look for thanks.
P.s one more question i now have 1X1gb ddr2 and 1X512 ddr2 and my mb only has 2 slot's for ram and in my country(lithuania) 2Gb ddr2 ram costs about 50$ soo should i have 3Gb's of ram for only 50$ or pay extra 50$ for 2Gb of ram caset and have some spare parts(1x 1gb & 1x 512mb). Will theres gona be a big diffrence in performance becuz of that 1Gb Thx,
P.s.s Im a Very low budget gamer.

i hope you can find a motherboard with a G41 chipset. it will not overclock nearly as well as a P35 , P45 or X38, X48 chipset but you have a better chance of finding it.

and sometimes it is difficult to know what chip is on the motherboard. lots of times you need to go to the motherboard manufacturer's website and see. hopefully it will be on the box somewhere.

just get the 2Gb. unless you have a 64 bit windows, it will only "see" the 3 anyhow. and also that is a very old system and parts are expensive. here you can get 8 Gbs of DDR3 (which is newer) for $50. so may may want to avoid spending a lot of money.

good luck and let us know how it works out.

The best CPU you can run in your motherboard is the 2.4Ghz Q6600 65nm Conroe based Core2Quad. They have not been made in years and are very expensive compared to a modern new CPU if you can even find one. You would be spending money on dead tech. The best thing you can do is save money for a completely new build.

so first of all sorry for reviving an old theme but recently remembered that two of my motherboard capacitors may be not working(i will try to send a picture of them) but the thing is that they are just above the cpu socket and the reason i think they are not working is because they got bend by trying to install a pentium 4 ht cooler (i know that was stupid) and although i got them back in to the right position but i think that they might be the problem and one more thing when i set the cpu voltage to etc. 3.165v i get 3.365v or even more and so on with other values of voltages i get more than i ask. so my question is can those two capacitors over the cpu socket be the problem why i cant go over 247fsb? and if so what can i do?

thanks,

Joris

so can anybody help?

i was wait for pictures   just kidding.

if your caps went south from bending them over, your motherboard would not be functioning. bending them over has as much affect as bending wire; none unless it is repeated several times until the wire breaks.

i am sorry to say that you have a lower end, older chipset with a lower end cpu, you will be hitting limitations rather low.

ok thats what i wanted to hear than i will buy a new mobo with ddr3 ram 4 gb   what do you think of this?
ASROCK S775 G41 VGA DDR3 MICRO-ATX LAN
and then i would get 2x2gb ram ddr3 p.s my budget canot exed ~100$ and in my country this would be about 100$

Don't...

Choices for LGA 775 boards are very limited since they are so old. I would go with whatever is cheapest. You don't want to spend money on obsolete tech if you can help it.

Do you actually need a new board or you just want to overclock? If you don't need a new board save your money until you can do a full system update.

Don't forget to get an aftermarket cooler if you plan on overclocking. The stock cooler will not work.

^+1
if you had a core2QUAD i would recommend getting another board. but since you basically have a pentium the performance gain you will get by overclocking it further is not cost effective for spending $100

when you are able to double that budget you can then get a much better icore pentium, a h67 board and RAM.
if you find a bargain it could happen for $160

i will get the quad core in the future but now im asking of help to chose a board that would have ddr3 mem support of at least 8gigs which my chosen board has an p.s the pentium e2140 is highly overclockable i saw people getting 3gigz out of it with a high performance increase so can you just help me chose a board please?

here:

now please understand you will NOT get that type of overclock. the chipset that was used to get that speed is NOT available anymore. IF you find one it will be VERY expensive and not worth it, you can buy a NEW board and cpu with the same money.

G41 or G43 will certainly allow you to overclock more than what you have now. The best LGA 775 chipset for overclocking was the P45.

DDR3 is not necessary with LGA 775 chips. They just can't use the extra speed. DDR3 is much cheaper than DDR2 at this point though. Core2 chips do best at a 1:1 ratio with the FSB and RAM. So 400Mhz FSB with DDR2 800 or 333 FSB with DDR2 667.

You will need an aftermarket cooler to overclock at all as I have said before.

so what board does have a p45?

you will have to look at what you can get and see if it has that. i could tell you several motherboards but NONE of them are being made anymore.
this is a problem because what you have is OLD. what overclock that they did was back THEN when there were lots of those boards. today it will be very difficult and EXPENSIVE to try and repeat it.

ok i just came up with this awesome gigabyte board (i always wanted a gigabyte) that although doesn't have a p45 chip (it has g41) but i think it is still not bad

GA-G41MT-S2PT

tell me what do you think?

It's better than what you have now. Just like all LGA 775 boards still available today it's a low end board just designed to work. None of the high end good overclockers are still available.

No matter what you might have read you will NOT be able to overclock with stock cooling.

Since you already have to upgrade to DDR3 either way and buy a new motherboard why not just save your money and buy a new CPU too? You will have to buy a CPU cooler to overclock what you have so you could put that money to a new CPU you would not have to overclock. An H61 motherboard and a Pentium G would be cheap and about 3 times faster than what you have.

i will buy the cpu next moth after buying the ram and mobo i know that it wont gonna overclock very high but i am expecting at least 2.4 ghz perhaps 2.66 out of my pentium
so what do you think about that board can i find any better in that price range? i mean that gigabyte is not so terrible right?

p.s i will change the cooling to

I almost always use Gigabyte boards for my own computers. I have one now.

ok so it is clear for me i get the board the ram latter the cooling and cpu and then i will get money to buy a new pc   any way thanks for your help guys you are the Best!
