Can't OC my E6400

Hi all,

I'm posting in this thread because my probelm is unrelated to the other E6400 OC thread. I'm using the vanilla P5B board and I haven't been able to hit anything over 2.13 stable at least. I was at one point able to run some benchies at 2.56, but Super Pi wouldn't run and I got crashes in games and even lower then 2.56 also.

I've done all the n00b checking, Thermal and Power saving settings in teh BIOS are disabled and I've tried settin' the vCore all the way up to 1.55 but it didn't make a difference. I left the memory either just above DDR800 speeds or a little below. I'm running the 0309 BIOS that was released on 08/14/06. I have the FSB voltage at 1.45.

So basically I've tried 3 different BIOS (0211 and stock BIOS before 0309), upping the voltages pretty high, I even tried setting the PCI-E to 110 (somebody on XS was getting good results with my board that way). I can't even get Super Pi to run at a 280FSB which is only 14Mhz higher!!!! WTF My system is water cooled so my temps are alright, nothing over 40C

Does anybody have any suggestions?
 
Hi , I too have used a P5B to overclcok a E6300 and actually they are quite nice to overclcok with , I got a 2.76ghz stable overclock.

I point this out to one person everyday and today its going to be you.

The art of overclcoking is you find the Max of what your CPU can run , meaning the lanes which are known as the FSB and then the Max of of what your Ram can run at , and then use your deviders to synchronise them both.

What is happening at the mo is that your Ram is letting you down.

What you do is set your ram to run at 667mhz and then work yourself up.
Some peoples DDR800 can go up til DDR1000 , like mine but I do not think your ram can do that and if it did you woulnt have made this thread.

ALso look at the leaderboard as a guide and set your voltages when needed be and do not at any time go near 1.55V , you can if you have watercooling but you dont. Your CPU will just cut off and you will have to clear CMOS.

ALso until you master your CPU FSB and find your Max ram speed , then only then play with the latencies and Vdimm,just leave the Vdimm on auto untill you understand whats happening.

Also write your findings down and you will see a pattern.
 
did you even read my post????

I DO have watercooling and my RAM isn't letting me down because I said I WAS using a divider and leaving the RAM jsut around the stock speed, it's never exact cept when the board is at either 320 FSB and I'm on a 4:5 divider or 400FSB with a 1:1 divider or 266 with a 2:3 divider, etc.

Sorry dude , read most of it but missed the watercooling bit, you have tried a few BIOS ,yes?

Check on the leaderboard and check NOOH and what he tried. Still you sounded as you were not getting any stable overclocks , if thats the case how did you get to 1.45 voltage?

Most of the people get about 400mhz increase without even increasing any voltage. Use it as a guiding tool. If anything its the best overclcking CPU on the leaderboard.

Take it from the beginning , reset cmos and set it at 4:5 or 5:4 , 4 being your ram at 667mhz if you can

\ps getting late , going to bed .

ROFL, again you must of missed part of my post.... I'm on the third BIOS I've tried so far, which is the latest one that seems to be the best for other people to OC on, released on 08/14/06. I will definitely look for your shiz and other peoples on the leader boards.

what exactly do you mean how did I get to 1.45voltage? Are you talking about my FSB Termination voltage or my vCore voltage?



One other question I have is this. My P5B only has a 4pin aux power connector, the P5B Deluxe and Wi-Fi version have the 8pin connector.... could this be causing my CPU to not be getting enough power or the mobo not getting enough power and thus causing the system instability? Also, I noticed in CPU-Z that my CPU code name says Allendale instead of Conroe, has anyone else seen that?
 
I believe that the 6300 and 6400's are called allendales and the higher ones are called conroes.

Lyquist
 
Yeah E6300 and E6400 are mistaken for allendales, Allendales are not out yet I believe
 
Wow you are getting tons of helpful replies. It is like you are hoarding them! Save some for
the rest of us!
/sarcasm

The only helpful question that I can ask is:
Are you using the OCZ psu listed in your signature? Have you tested it recently to see if it is
still doin' its thang?

Hopefully persons with more Intel knowledge will show up and offer their adivce....
 
me thinks it's gremlins.


...or psu like above poster--can't tell for sure what psu ur using.
 
Have you tried dropping your ram divider down to something that will run it lower then 667, like at 533 or 400 and then tried upping your FSB from there? Keep upping your FSB up 5 to 10 mhz and work your way up. Have you tried loosening up the ram timings?
 
Hello, yeah my sig needs to be updated lol.

Anyways, I am still using my 520 OCZ Powerstream. Are there programs you can use to test it? voltages look good in monitoring programs and such and it never faltered when I was using it with either my 3200+ system or my Opty system.

As for my RAM I'm running OCZ DDR800 rated at 4-5-4-15 but I'm runnin it at 5-5-5-15 and the lowest I've tried running it at is 350MHz (DDR700)

/me reboots to try some different RAM settings
 
I'm having trouble too. I have the following settings that run stable but I don't know what to do from here

DRM: 800mhz
CPU Frequency: 290
Ram Voltage: 2.1v
Current Clock Speed: 2.33ghz
 
okay so I'm runnin at 2.4 now, FSB is at 300, I really don't think it's my RAM though, runs flawlessly at stock DDR800 speeds with timings of 5-5-5-15 when the FSB is at sock 266. I just tried FSB at 333 with RAM at DDR-667 speeds with timings of 6-5-6-15 and it POSTed fine but no windows, restarted when it got to logo screen. Now I'm running FSB of 300, RAM at DDR600 with timings of 6-5-6-15.

I can't tell if it's my CPU or my motherboard, that's really what's peevin' me off
 
now I'm at 315, didn't do any stress testing, but just to see if I could boot to windows and I can now. Actually I'm willing to bet I could boot at 320 as I already have, but anything over 266 I can't even run 16k Super-Pi in, this is really starting to piss me off :mad:

Did I just get a shitty CPU?

I was able to run Super-Pi ONCE at 1MB when I had my FSB at 320 at 21seconds, but other than that I haven't been able to keep this damn board stable at anything higher than stock.

okay so now I tried Super Pi at 315 and it worked.... weird....

Now i'm at 325 and it doesn't work at all, it doesn't even go into the first loop, aaahhhhhhhhhhhhhhhhh

something else is weird.... my voltage settings are all on auto in BIOS and yet my CPU vCORE according to CPU-Z keeps increasing when I OC more, is that normal?


edit:
tried booting at 330 and got BSOD.... also, is having spread spectrum enabled or disabled good/bad??
 
throttled back to 315 and Super Pi stopped working at that FSB too.... BAH

and in case I didn't say it before, my PCI is locked at 33 and my PCI-E locked at 100, has been since I started all of this
 
Did you try the older bios? 0170???

Reset your CMOS and start over from there...


Seems like you might have hit the wall with your processor... Overclocking is not guaranteed...
 
meh, I already sold this board, reading others posts not many people seemed to hot on this board. I'll repost when i have my newer mob0 and see if it really was my CPU, meh

I really don't think I've hit the wall when this thing isn't even stable at anything over stock.... so lame

and yes, I've tried the older BIOS, I tried taht one, 0211 and 0309 none of which were successful, bah
 
hey, thanks for the suggestions guys, I sold my P5B and got my P5W DH and I'm sittin' at 3.0 stable right now, 2 instances of Prime 95 ran all night long, 3.2 stable for games just not Prime stable.
