E4300 + Asus P5B-E Plus = disaster!!

[Musslan]

Hi!
I recently bought the following system with some overclocking in mind:

E4300
P5B-E Plus
2x Twinx2 1024mb PC6400
Radeon X1950XT 256mb
Corsair HX520 PSU

I use 0504 bios

I have som big problem reaching above 410 fsb.
I know that the board AND the cpu are good for some nice results.
I have cranked up all the voltage in bios and disabled everything that are unneccesary.

Max fsb is 400fsb and even the cpu begin to act weird above 2900 even with 1.5v and more :(

Plz help me out guys

what is the FPO/batch of your E4300 ??

[Musslan]

Fpo : Q634a290

[messerchmidt]

what fan/heatsink are you using?

also, did you do any vmods?

[Musslan]

I use the stock heatsink.
At 2700mhz I get 42/55C idle/fulload

No mods, I bought these components in belief that I could atleast reach 450fsb and 3ghz but I fail at both of them :(

I need some serious help here :(

my chip will not clock over 400 FSB (had Vcore up to 1.55)
The highest I've seen was 4Ghz on phase change mach II at 1.6 Vcore.

running 3.4 Ghz at 1.38 Vcore

Well, your cpu goes atleast over 3Ghz.
Mine will not even do that!

Can someone confirm that the week 34 E4300 is just crap or is it something else?

I begin to think that I´ve got two POS components on my hand :(

Perhaps you're over-volting something. Could be the ram, the cpu, or the chipset. Find your stable clock and then slowly push it up, and adjust your voltages along the way.

It also sounds like you're using the x7 multipler which could be a big problem, due to the theory that the northbridge core clock would actually be 1.29x what youre setting it at (9/7=1.29x410=527mhz, which it ain't gonna like) My most sucessful overclocking with my E4300 has been with the x8 multipler.

Hmm thats a bit interesting.
For max FSB testing I´ve used the x6 multipler.

So you can overvolt the components and get worse o/c results?
Because I can runt at 6x400 with no volt adjustment at all.
But as soon as I exceed 400fsb it doenst matter what differnet voltage the cpu, ram or the mobo gets :(

Do I need the exact combination of the different voltages to get a successful clock?

if you can hit 400fsb and you can go all the way to 9 multi then there shouldnt be an issue maxing out this chip whatsoever :confused:

No, I know but I want to reach up to atleast 450 ;)

My cpu is saying no no at around 2.9Ghz anyway :(

[Fr3ak]

400*9 doesnt sound too bad for me...

Using low multis is not the best method to test the max oc. Better stick with 9x and try to oc past 2900mhz.

[Musslan]

I´ve tested the cpu over 3Ghz with alot of volts and it doesnt help. I can boot with 3.15 but cant get pass the windows logo without BSOD
And this with 1.6vCore

I dont want to put more volts due to my stock heatsink :(
The temprature rises to fast when adding to much volt.

I´ve tested everything in auto and 400 is fine but then its impossible,
I cant understand how my Plus board cant reach 410 and above when the majority of the clockers here can do 450+ without any difficulties

[Fr3ak]

I bet they arent using a E4300.
Most E4300 have FSb walls at 360,hz and above. A few goe past 500, but thats really just a few.
Did you run the tests you are talking about above with the stock 9x multi or with 6x?

[SoF]

didn't heard about fsb wall on 4300 until now.
really that hard fr3ak?

[Fr3ak]

I dont know if it actually is a fsb wall or if the mainboard bios needs some fine tuning, but have a look at E4300 threads. There are a lot that cant go over 380mhz ish FSB. Dunno if its just a bad week or a general issue.

[Musslan]

I´ve tested with x6 multiple every time just to put the cpu "out of action" when tuning the fsb

Do you mean that the e4300 doesnt like high fsb?
How come a cpu bother what fsb that Im using. I thought the cpu didnt care whatever the fsb was 200 or 500 as long as the multiple puts in to the freq intervall that is possible

[Fr3ak]

There are certain theories that mainboards (especially 965 and 975) dont like to run CPUs on a lower than their stock multi.
Its still not completely clear why that is the case, but there seems to be something true about those theories.
I bet you can get past those 3ghz with the stock multi of 9.
There is no benefit from running a higher fsb with a lower multi compared to a high multi and lower fsb anyway.
And if the CPU/ board combo can do 400Mhz, that would mean 400*9=3600Mhz. That wouldnt be bad, dont you think?

[xtrempinoy]

ive hit the ssame FSB all 380ish and my system in unstable. i use the 8x multiplier .. and nothing... im thinking its the processor.. i might pick up a e6300 just to test out this theory.

[Musslan]

Yea I begin to draw the same conclusions as you guys.
Now I try to get the thing stable @ 8x375 = 3.0Ghz@1.30v

But I notice that the cpu isnt stable with 1.3, can be the multiple that screws up the stability.
I will test with 9x350 and 9x375 and if our theory is correct this would result in more stable platform with lower volt.

As it stands now, I might sell my e4300 for an e6300 or 6400.
I like high fsb rather than just high freq on the cpu.

But do you guys try to tell me that it doenst matter if I run high fsb at e.g 3.3Ghz or low fsb at 3.6Ghz?

Thanx for the input guys.
Plz post some updates if you come up with other theories

There is no benefit from running a higher fsb with a lower multi compared to a high multi and lower fsb anyway.

This statement, by itself, makes no sense to me. This implies that only the cpu clock speed is important.

Increasing the FSB decreases latency and increases bandwidth and overall performance. Increasing and improving the FSB speed of intell cpu's, chipsets and motherboards has been going on since the beginning of time; where have you been? The current market is pushing up to the 1333mhz FSB.

I understand the benefits of using the top/max cpu multiplier in some cases, but it is not "the" ultimate goal; overall "system" performance is. This is my understanding, such as it is.

[Musslan]

I agree with you.
I got really confused when someone stated that it didnt matter.
Ofcourse you want a high fsb in your system.

But I guess the E4300 doenst want to play at around 500fsb

[dekruyter]

500 fsb w/ an e4300 is quite an achivement, I believe; you'll have to have all your ducks in a row, and some luck maybe, for that one to be stable 24/7.

[dsaraolu]

Asus P5B-E Plus (bios 0304) + E6400 is OK. All on air.

[ineedaname]

I don't get it. Why do you want to use 6x and 7x multi so badly?

Have you tried using the 9x multi and doing 3ghz+? I highly doubt you need 1.5v to get over 3ghz that's just making your proc hot, try using 1.4v. or just stock voltage if you're using 9xmulti at 3ghz. Just set the fsb to 333x9 and you're already at 3ghz. And your actually bus speed will be 1333.

Also 55C at 2.7ghz is a bit high. You probably need a better cooler or try resetting and reapplying your thermal paste.
