dilemma! should i switch or not? p5wdh to p5b deluxe for the each 300-500mhz overclock?

currently stock voltage at 3ghz running stable.

i have a intel core 2 duo e6300.
and with
F2-6400PHU2-2GBHZ ---DDR2 800 4-4-4-12 2V

BIOS SETTING

http://www.gskillusa.com/motherboard/p5wdh/04.jpg

my setups like this are stable on 2954mhz
superpi 32m passed
7hr prime stable




currently running



was wondering how i would get this stable?

right now, it won't pass superpi32m. i want to be able to pass superpi. any help would be greatly appreciated.
 
You're running near the limit of the 975X FSB. The only thing you can really do is bump up your MCH voltage and hope for the best. Possibly replace the stock cooling with something else on the northbridge or at least get a fan on it.
 
you are running a 430MHz FSB 860MHZ memory frequency if on a 1:1 ratio with memory rated 800MHZ.

you could try another .1 volts of memory voltage to 2.1 volts but thats up to you, I am not up on your memories max voltage.

Loosen your memory timings to 5 5 5 -15

tried this already 5 5 5 -15 on 2.1v. no pass

mch already on 1.75v



should i just lower the ratio? would that lower the ram performance a lot? would i be able to tell when i'm using the computeR?

No, you wouldn't be able to tell if you lowered the memory ration by one step. If that doesn't help, I think you're just running at the limit of the 975X chipset's FSB. 430mhz is a lot. The only thing you can do is get better cooling and see if you can get a few extra mhz out of it. Most of them don't do better than 430mhz anyway, especially with stock cooling.
 
currently able to boot. 3.1ghz ram set on 5-5-5-15 running on 663mhz
but not sure if stable. still testing
 
Should have went with a 965 series for the e6300. With the lower multiplier, you need the higher FSB limit. The 975 is great if you have say a e6400 or 6600.

yeh too bad. i was thinking if i can get stable at 3 i will just let it go without going into the trouble to swapping motherboard and buying a 965. to much trouble.
 
Definitely try 2.2 volts on the memory. Most performance memory is rated for this anyhow.

Here's a good review how D9GMH chips scale with additional voltage.

When Micron uses these chips on their DDR2-667 modules it sets them at 1.8 volts.

A little more juice definitely makes them perform.

testing to see if this will work


bsod at 3.1
testing 3ghz 4-4-4-12 @ 2.2v 1:1 ratio
 
Put a fan by your northbridge cooler and see if that helps your OC.
 
if those are the G.Skill HZs you can run 2.35 volts through those easily, I ran mine at 475mhz x2 4-4-4-10 stable as a rock.
 
they are

Ram - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Unbuffered Dual Channel Kit System Memory Model
F2-6400PHU2-2GBHZ - Retail
 
Your really close to the limit, not much can be done. Try cooling the chipset, try raising your pci-e bus speed a few notches. Raise your FSB a few more MHZ. Raise Vcore a bit. Or buy a different motherboard or a chip with a higher multiplier.

I just finished reading a few reviews and they all get 200mhz overclocks at least with 4-4-4-12 2T running at 2.3v. Anandtech was able to get it to 1065 with 2.45 at 5-5-5-15. I'm going to shoot for 1000 4-4-4-12 2.2-2.3v in a few.

lower timings are better on the Conroe than higher clockspeed (RAM here... CPU clockspeed > ALL)

Having 3.2ghz clockspeed is much better than having 1200mhz RAM.

Having 4-4-4-12 @ 850 is a bit better than 5-5-5-15 @ 1000
 
I didn't read the whole thread, but I have the same ram that is running at 451x8 4-4-4-8 at 2.2v. My guess is that its the mobo.

Hi, how did you get your set up right, trying all sorts here and no joy, 2.8+ max.
pissing me off, as complete water cooled system is not being put to use:mad:
