so, i can boot into windows at 3.5 but i can't get stable. someone help me get up there. i can do a good 12 hr stable on current settings in OCCT full stress. load temps range from 60-65 on TAT

You could try to bump a few of your voltages a little bit, but beware of temps. That's a nice oc, check your NB temps though.

which do i bump? and how much do i bump it by?
which prog will let me check my nb temps?

I have the same board and the same ram as you. I run fsb, nb, sb at the same voltage as you have. My ram is at 500 5-5-5-12 @ 2.1v, try that. Not much performance difference from 4-4-4-12. I use 3-11-5-12 for sub timings. Also. I disable spread spectrum. Vanderpool tech is also disabled, even though I don't really know what it does. Good luck.

if you want to hit that point, read this thread! you HAVE TO DO THIS MOD! ITS AMAZING!

will give that a try right now. i disabled the spred spec and the vanderpool stuff.
gonna try your timing

what thread? what mod?

I have used that same ram/board/cpu and i've hit 3.6ghz.
You should probably post some of your temps.
I know the NB really needs some extra cooling on it.

if you ask me 1.5v is pretty high. For the p5b computer i built it only needed about 1.42V to get stable at 3.6ghz. By adding too much voltage you could b causing the cpu to get too hot.

[noktekniq]

just did a search on the vcore pencil mod. just took apart the comp to do the vmod. trying it now

[noktekniq]

not exactly sure what the pencil mod did except balance out the volt pretty good. as for better overclock i haven't seen anythign better yet. sitll trying.

[noktekniq]

any help would be interested!
is my ram bottlenecked?

I have almost similar setup, and the Ram and Board are less likely to be a problem here. Your chip must be a good one to do 500x7 24/7 stable.

Check out Freecableguy's thread for P5B-Dx BIOS screens, you should find your solution there hopefully.

Anyway, for 3.5Ghz, the followings are recommended:
+ Vcore = from 1.45 to 1.60 max (unmodded retail boards drop quite a bit, so dont worry too much)
+ Vdimm = 2.3-2.35, put a fan over the modules
+ VMCH = 1.45-1.55 (if you want to run 1.65 for 24/7, update your NB cooling)

To test your CPU's ceiling FSB, keep vdimm but relax timings to 5-5-5-15, then boot and clockgen/setFSB in windows until...it crashes. Board should do 500+, Ram should do 500+ with those timings, so on air your CPU will cap out first, note that FSB.

Reboot, reduce about 50Mhz and test for stability, when it's stable, retweak your ram to run tighter =) (don't forget to adjust voltages to the lowest stable possible value, helps with Temp and prevents degradation)

If you are lucky you will have a 3.5Ghz C2D and mem at 500Mhz 4-4-4 for daily use. Good luck.

disable the vanderpool tech! You can only change this setting on a cold boot. This setting allows for virtualization on a hardware level. You dont need this enabled..... Might free up some overhead.

I o/c up to 515FSB x 7 with my E6300 & P5B vanilla. It ran all my programs and tests fine, but my cooler is not up to the task for longterm o/c at this level. At 470FSB @ 1.30v the temps are much cooler and there is not much difference in performance from 515FSB.

well if you check your voltage when your overclocking under load, the board has a pretty bad Vdroop.. like EXTREMLY BAD in my case.. if you check out the resualts that i got before... i went from max 3.255ghz because the processor kept drooping to 3.4ghz stable with only 1.3125vcore on the processor...(i could go higher, but temps are already 65+)

did the mod, but in my case ic ant' find 3.4 stable. still testing ! :banana: :banana: :banana: :banana: :banana:
