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)

Is the system stable at stock settings? It's always good to have at least that as a baseline.

 

[kschaffner]

Yeah I can run anything at stock settings and nothing goes wrong. But if I change anything it just gets foobared.

 

[kschaffner]

I will be running prime 95 for at least 8 hours when I go to bed just to make sure that is at least 100% stable.

Maybe your PSU can't give the juice needed for your Over-Clocks ?

 

[kschaffner]

I ran a 3800+ X2 at 2.7ghz 24/7 and had it at 2.8ghz for benching. It should be able to run this with ease. Less juice required.

*edit* socket 939 btw

Make sure you have the latest BIOS for the board. The current P965 boards have an issue with 4MB L2 cache chips.

 

[kschaffner]

I do, I dled the latest one off the asus site.

What is the highest bootable FSB? Have you tried running memory slower than FSB? (below 1:1) I know it's not the ideal config but you need to find out what's holding your FSB first.

 

[kschaffner]

I got 428 bootable and I could run firefox with wmp and it would be fine but any stability progs would cause it to crash. Yeah I put my ram at the lowest Divider I could.

No matter what you say, your power supply is what's holding you back. 20A on the 12v rail isn't anywhere near enough for overclocking a Conroe. Download this: SpeedFan 4.29, and tell us what all of your rails are reading. I'm guessing that your +12v rail will be low, even at stock speed.

edit: Also, you do know that your motherboard hates running RAM at anything except 1:1, don't you? Leave the RAM at 266, then overclock from there. And also make sure that you're giving your RAM 1.9v.

COREA 2.58v
COREB 3.74v
+3.3v 3.31v
+5v 5.56v
+12v 12.10v
-12v -13.03v
-5v -5.04v

 

[Some1ne]

Speedfan doesn't always give accurate readings on the P5B Deluxe (or at least, it certainly doesn't on mine). I think you might be better off trying the software Asus bundled with the board (PC Probe II, I think).

 

[kschaffner]

Asus probe II reports
Vcore 1.29,
+3.3v 3.31,
+5v 5.22,
+12v 12.36.

I now have a 3.4ghz occt and 32m super pi stable oc. I reflashed the bios in hope the first one was buggy. Still using 0507 just reflashed it from a different site.

[akshayt]

Only 20A on the 12V lines, this may be the culprit.

 

[kschaffner]

It is not the PSU I have a 3.4ghz stable oc right now with that same processor I just reflashed the bios.
