Hi,

Im having odd problems with my overclock. My computer is:

P4 3.2E EO SL7Pn@ 3.841ghz (cooled by H2O)
ASUS P4C800e DLX Rev. 2
2x512mb OCZ PC3700 Gold Rev. 2

I recently upgraded processor from a 2.8C to a 3.2E EO SL7PN. I was able to run 1:1 with my 2.8C and I seem to not have the likewise success with my pressy. My fsb is currently 240mhz. Vcore and DRAM frequency are set to auto. I set the vdimm voltage at 2.85v. With these settings my cpu was able to successfully pass memtest 86 Rev.2 and prime 95.

My problem is this: When I have my DRAM Frequency set to 400 and manually raise vcore to 1.4 and 1.45 manually and with fsb set to 240 I get errors in prime 95 in a few minutes and get a few errors in test #7 with memtest 86 Rev. 3.2. Some times my computer will even reboot.

I have my memory settings at 2.5-3-3-7 and dram burst set to 8.

Why am I unable to run 1:1 (DRAM Frequency set to 400) at 240fsb settings with this processor. Is there something wrong with this ram, settings, or could it be my powersupply due to pressys draw more voltage than a northy? The lowest my rail ever went in asus probe was 11.98 and fluctuates very seldom. My temperature is only 33-35 degrees celsius.

Well I loosed timings to 3-4-4-8 and now I am prime testing at 1:1. At 3:2 I easily got 4ghz with dram frequency at auto and vcore set to auto. will post pics in a bit.

Nice! E0's seem to overclock higher at default vcore. Do you have the 14 multi option?

no I dont believe I have multi option. Well it seems my issues above may have been related to to tight of timings at 2.5-3-3-7. I upped vcore manually to 1.425 and backed fsb to 240 and am testing it at 1:1 at moment in memtest and upon successful completion will prime it. Wonder if I should save up for some other memory to get better results or stick with these?

1:1 is ofcourse better if the timings are good. 5:4 with tightest timings is good also. Right now Im running bh5's @3.6v with 2-2-2-5 timings. your ram should atleast be able to do 250fsb/5 * 4 = 200 Mhz with tight timings. As for the lockfree; "Lockfree enabled/disabled" options in bios, it's there if you have it. sl7pn has Loadline B according to intel spec so you might not have it though

If you can get those kinda OC's on that kinda voltage, start crankin :p. I have my 3.2e (DO stepping) at 1.46 (4.0 Stable). .6V aint gonna hurt it, try upping to vcore and see if your 4ghz turns into 4.1 :p.

well I failed prime 95 after a little over an hour at 1:1 at 2.5-4-4-8 with this memory. Think I need better ram to accomodate this processor. well decided to press it a lil farter at auto vcore and auto dram frequency. Here's 3:2 stepping results...
