Can't oc e6600.

[kschaffner]

You name it I have tried it. Fsb from 300-450, multi from 6-9 vcore from 1.325 to 1.6, fsb term to 1.55, nbvcore 1.35, I have tried everything under the sun. I cannot get 1 stable oc no matter what the speed or the vcore I fail super pi 32m, occt, prime 95. I'm not sure if it is my mobo p5b deluxe/wifi-ap or my e6600 retail conroe.

Specs:
MSI 500w 20a +12v rail
Intel E6600 Retail (stepping 6 revision B2)
Corsair XMS2 2GB DDR2 800 (CAS 5)
Zalman CNPS9500 LED (Artic Silver 5)
Asus P5B Deluxe/Wifi-AP (0507 BIOS)

You mean it get unstable when you raise the fsb by 1mhz? If so, does this happen with all multipliers?

[kschaffner]

Yes. Every multi that I can use 6-9 it will run unstable. I'm not sure wether it is the MOBO or CPU that is causing this hinderance.

Take the box to you local dealer.....

[kschaffner]

Why would I do that. I am trying to figure out what part is foobared so I can RMA it.

*edit* NVM my dumbass was in the way. I see what you mean take it there to have them test the parts in a different rig to see how stuff goes.

Tried RAM on SPD? Dumb question I know, just checking.

[vintage_guitar]

tried locking the pci-e speed to 100?

[kschaffner]

Yup did both.

[alexio]

If 1mhz increase of the fsb causing instability there is a good chance that the bios is buggy. You could try clockgen to oc in windows and if that does work you should reflash or update the bios to the latest version.

Run memtest

[kschaffner]

Did, passed 8 tests. On the good stick of the 2. 1 is bad but I found that out right away.

[Mr.Kakarot]

I reset bios defaults. Then did you disable ht3, and dram throttling?

leave your memory settings to auto for now... and just try to boot....

change your ddr800, fsb 400, voltage 1.55.. I think that is all I did and it booted at 3.6

[kschaffner]

The ram is not the problem I can run it up to ddr900ish with memtest reporting no errors it is the processor stability itself.

I will try to help. I think you are making too much changes at once and so you can´t know what´s wrong. There are several problems with 507 bios settings, that result in no boot or not stable. I would try this:

boot at stock
change memory from auto to 533 and memory voltage to 2.1 - the memory must always run 1:1 with 507 bios. Input the memory settings manually, try 5-5-5-15-5-30
save and boot, if it boots, then your memory settings are ok (memory will be running 533 for now) and you can proceed - disable everything under cpu options (or everything except multiplier control), disable all unnecesary devices - wifi, usb, audio etc and disable spread spectrum
save and boot and if it boots you can try overclocking the cpu (or maybe go into windows first, to see this is stable).

While overclocking the cpu you should first try to avoid fsb between 300-400, so I would suggest you try 7x420 or 8x400. Only if this doesn´t work, then try something with the default multiplier: 9x280, 9x300 etc. Don´t change any motherboard related voltages (I can run FSB475 with everything default)

If this doesn´t work for you then I think some of your components are broken. As a last option you can try 502bios, but there are different settings again.

20A 12v rail sounds awfully weak to me as well, whats your videocard?

[Nasgul]

Have you tried it this way: http://www.xtremesystems.org/forums/...d.php?t=112303?

Also, what kind of PSU you got under that system? Hopefully not an Antec.

[kschaffner]

I have a MSI. GREAT NEWS. I reflashed the bios in hope that the first one was bad. BAM I have a 32m pi, occt stable oc at 3.4ghz. I am currently running a 8 hour prime 95 test. 1 more question though. Asus probe said I hit 65C is there any way to drop this. I have a Zalman cnps9500. I Believe the voltage is 1.425 or 1.45.

[herderien]

you flashed from windows with bios 0507 ? or from EZflashstuff

[kschaffner]

I put it on a floppy. I got it here http://www.dvhardware.net/software/5906
