alllright lets get to business. i've currently got a stable oc, of course im not pushing my system to its maxium or anything. ill have everything including voltage readings(from apps, yeah i know) below. its currently just a tad below.

oc'ed to 2.5~
its at 355x7
vcore is 1.25-1.275
ram is 888 right now...it can apparently do 1ghz pretty well
running 5.5.5.15 latencies
stock ram voltage right now as well

i want to hit higher, and im not epeening, but i would like to max this thing out before i head out for a year and such to know that my rig will be more than well off when i get back and upgrade/possibly sell this comp and build a new one in a year to a year and a half. if i push the voltage up to 1.325 to 1.35 and pump the cpufsb over 400, it wont post or anything.

edit: temps right now idle is low 40's and into the high 30's, load is high 40's into low 50's. i have a scythe infinity so temps wont be much of a worry, i have a high flow panaflo as a case fan right behind it, i can post pics if needed. temps are taken with load from TAT, orthos is posting me into the high 40's with room to take it higher.

Set your memory to DDR533
CPU volts at 1.45
MCH V to 1.4 or 1.5
set ram timinings and volts to spec
FSB to 401


See if that works

1.4V is nothing ;)

Doing over 1.6V, now that might be pushing it.

As long as temps are decent (80C is max basically), & you keep vcore below ~ 1.5V, you'll be fine.

The reason it's not posting @ higher FSBs is that you're using the 4:5 RAM divider.
Set that to 1:1, or so it's exactly double the FSB speed in the P5B Deluxe's bios.

I've never killed one yet and I've put a lot more than that through em. I said 1.45 so you can test how far it will go. My E6400 will do 2.8 401x7 with 1.375 but it takes 1.475 to get orthos stable at 3.2 401x8.

You can do 1.4 to start, then start working your way up, you will likely have to icrease the MCH, and FSB volts more as you get higher. If you can get up around 500 you will also have to increase the ICH and SB volts.

You should be able to get to around 450 with 1.475-1.5v cpu and 1.45-1.55 mch amd 1.4 fsb volts and the others on auto

what exactly is mch....i'd rather talk through aim/yahoo if you have either or. make things much easier. i think it probly is the 4:5 ratio....which one will work better, im not sure how high my ram will go.

well i managed to hit 3.2ghz, im gonna test for stability overnight and see if it works, but im gonna do a little gaming first...it seems ok, ill run TAT to see what the maximum temperature i hit will be, question, i open cpu-z, and it identifies my cpu codename as Conroe....yet the power supply calculator that everyone uses, identifies mine as Allendale...which one do i believe, im thinking cpu-z.

Don't have an instant messanger installed on this machine

MCH is called "NB voltage" on your board

Here is a good thread that explains all the bios settings on your board
Text

I would start with

CPU frequency 401
DRAM frequency DDR2-802mhz
PCI Express Frequency 100
PCI Clock Sync 33.33mhz
Sread Spectrum Disabled
Memory volts 2.2v
CPU Vcore 1.45
FSB term volts 1.4
NB Vcore 1.55
SB Vcore auto
ICH Chipset auto

Set the ram timings as listed to
5
5
5
18
5
42
10
10
10
11

Then start going up with the FSB, the DDR frequency will also go up but don't worry thats why I show 2.2v for the ram and loosened the timings way up.

Once you find your maximum CPU overclock you can start lowering the Dram volts and timings to find what works best

:thumbsup:

I see I was a little late:) , you appear to be well on your way. It's trial and error from here on. If it fails at 3.2 up the vcore and/or play with the DDRvolts and timings. If it proves to be stable you can either choose to go higher, or start testing with lower volts and timings. The object is obviously to get the best CPU overclock you can, then work the vcore,ddrvolts, and ram timings to the lowest possible with your overclock.

Good luck, and let us know what you come up with

All of the earlier 6300's were conroes with 1/2 the cache disabled, but just here recently they released the Allendale versions with a native 512mb cache. If you just got it recently you will have to check the stepping to be sure. B steppings are conroes and F or L's are allendale, I don't remember. I tend to agree that CPU-z is probably accurate, but it doesn't really matter

the picture is obvious as to what this is....im interested, why i couldnt get it to go above 3.22 stable, even borderline 1.5v it wouldnt stay stable, as soon as i started up orthos it would freeze....voltage problem? cpu-z is only reporting 1.4 instead of 1.45, would i need a voltmeter to actually check voltage?

cas latencies, it seems all good right now, we'll find out overnight if its ok or not.

Yes a voltmeter is the only way to get completely accurate. Windows utilities like CPU-z always show less than what you set in bios thats called vdrop, and then once you load the CPU under orthos it drops a little further that difference between idle and load is called vdroop.

Where your at a 455fsb it could be you need to increase the NB volts, or Dram volts, or loosen the ram timings(see you've already done that), or you could be getting to the CPU's max. You will just have to play around with it. List all your voltage settings

well dram volt is set to auto, i can try 2.1/2.2 but its in the red on the bios...heh. im happy with this as it is, its probly the cpus max..i'll get a voltmeter sometime soon since i need one for my car as well to check all my engine grounds n such, 2nd gen rx7's are electrical hazards, not to mention fire hazards(for those of you who know what the pulsation dampner is).

You have the gear but you will have to tinker with the settings. It is remarkable how one motherboard setting(and don't ask me which one, this seems to be random and dependent on luck and your mobo) can make all the difference for overclocking. For me it was setting the PCI-E to 100 instead of auto. Overclocking is a bit of voodoo and luck when it comes down to it. Good luck. ;)

when i run the orthos cpu only test, my cpu works fine, when i run the cpu/mem test, it fails...i've relaxed the timings, increased voltage to 2.3 for a little bit(didnt wanna do it too long) and it still wont show as stable on it, im gonna run memtest sooner or later, and see if its my memory that cant handle being oc'ed, but its not even that high of a oc on the ram...

whats your NB volts set at? Overclocking the ram puts more stress on the north bridge chipset. But you are most likely hitting the top on the ram running 1:1, I have OCZ ram based on the same PROMOS IC's as yours and 450fsb DDR900 is the best I can get running 1:1 with fsb. Strangely with the 4:5 divider and a lower fsb I can get it almost to DDR1000

Yeah. I've got a Q on a similar subject so I might as well ask it here. The MCH on the eVGA 680i is 1.5v minimum and I've OCed my rig considerably (450x8, DDR2-800 @ 900 4-4-4-11). Do I need to boost it above the 1.5v?

Try bumping it up to 1.55, the max should be 1.65 or higher per the sceenies I linked in a prior post

If its stable leave it where it is

above 900 my RAM gets shaky. so bumping my vMCP to 1.55v may help? my vDimm is 2.3v and vMCH is 1.5v, and vFSB is 1.5v (the max).

well i tried the 1.55v, and it wont post....im not going to try 1.65v because thats just a bit risky, i dont think i have the proper cooling for that much of a jump, i'd hafta change out my northbridge cooler and such to probly run that high wouldnt i? how would i get this to be orthos stable, because im getting one error, and it says rounding was .5 and it expected .4

Well it really sounds like your ram is your holdup, if it will post with NBv at 1.4 but not at 1.55 then NBv is not your problem. As I posted earlier my OCZ ddr2-800 won't go past ddr2-900 runing 1:1 no matter what I do. Unfortunately your probably going to be limited to 450fsb or less with that ram:( . But look on the bright side 3100-3150 is pretty damn sweet for a <$200 CPU:) faster than the most expensive chip available at stock speed.

yeah, it seems to be my ram like you said, i'll be happy with 3.15ghz, its a substantal oc over my stock speeds, and i'll be happy with it for the next month till i leave. thx for the info on how to do it, i wouldnt have ever bothered to figure it out otherwise.
