e6300 + P5B Deluxe Overclocking

Lithium · 25 Nov 2006 at 20:01

Hey chaps!

I've gotten this up and running, unfortuantely i cant seem to hit more than around 2.65ghz.

e6300, P5B Deluxe, OCZ 6400 "crossfire certified" with a Tuniq Tower in a P180 case. Plenty of cooling and around 50C under load.

Anything past 2.7ghz and GO fails in under 5 minutes.

I have followed these settings that i found on a website somewhere.
(except for the FSB bit which i have incremented up slowly)

Any suggestions?

DRAM Freq, 800mhz? Or the lowest it will go? Plus have you set all the settings as the other photos show?

Set the PCI-E frequency to 100mhz :E

Set ram to 2.2

Set VCORE to 1.40

Set DRAM frequency to 800mhz

Sorry yeah i had my pci-e at 120, didnt want to push it too hard.

My vcore is now at 1.4 and dram frequency has always been at its lowest. (so when fsb is pushed it sits around 800mhz)

I'll try increasing mem to 2.2 see if that helps but so far no luck!

RAM is set to 1066 there... unless it isn't your pic

No its a pic from a forum

Ok so now i'm at 2.86 something or other. I can play oblivion ok (at least it worked for the hour i tried, which it wasnt before)

However GO doesnt work so well, i am using a beta version however. Is GO a reliable testing method for stability or could i be trying something else?

*GO* Or is it called Orthos? I dont know

I think it could be related to memory somehow.... quickpar is throwing up failures and suggesting its a memory error.

Plus when i run Orthos with just CPU stress it works fine.

I'm running it at 4-4-4-12, its OCZ 6400 cross-fire certified and should run fine past 800mhz! (its at 1:1 however i cant seem to hit more than 2.8ghz)

Did you set the settings shown on the other slides?

If you have then set this:

CPU Vcore: 1.45
Mem V: 2.15/2.2
FSB Term: 1.4
NB V: 1.55V
SB V: 1.5

Yup all those settings are good.

When using orthos "blend" test it tends to fail very easily for me, even at a paltry 2.7ghz. However the CPU tests that dont involve memory tend to last forver.

Well i reset everything to default clock speeds and ran memtest86+ overnight, it ran flawlessly for 10 hours and did 8 passes.

So i'm fairly certain my ram is cool, however soon as i clock up i start getting errors with windows memtest, going to try clocking up and running a memtest86+ test.

Is it normal for memory to be the cause of problems? I mean i can get my machine to post to windows at 3.2ghz easily and its fairly stable, it just comes up with memory errors in memtest and orthos fails. (even though oblivion worked ok for the hour i played it)
