lol it finished fine and maxed on one core at 54 degs

doing a windows 7 rating to see if it goes up from the 7.2 stock score, doubt it but we will see.

paradisiac · 10 Dec 2009 at 21:06

well the ram is downclocked to 800mhz instead of 1066mhz, and its score along with the cpu has gone from 7.2 to 7.3 which is odd.

cmndr_andi · 10 Dec 2009 at 21:10

Don't pay much (if any) heed to the stupid windows score - it really doesn't mean anything.

paradisiac · 10 Dec 2009 at 21:15

well i took it to 450x7.5 and it didnt like that at all

will try 425x7.5

cmndr_andi · 10 Dec 2009 at 21:16

Have you upped the voltage yet?

paradisiac · 10 Dec 2009 at 21:18

yeah to +0.075
the ram on auto is running at 800mhz but it seems happier like that, so just leave it?

paradisiac · 10 Dec 2009 at 21:19

vcore on OCCT is reading 1.3-1.31

cmndr_andi · 10 Dec 2009 at 21:20

Cool

Aye, I'd just leave it at 800MHz, should stay nice and stable and you won't be loosing much performance.

vcore on OCCT is reading 1.3-1.31

Nice, you can afford to bump it up another 0.1volts if u need.

paradisiac · 10 Dec 2009 at 21:23

so do you think the not like 450x7.5 might be down to i also set it to 1066 ram?
should stop being inpatient and do 1 thing at a time

but 25mins between each change is too much hehe

cmndr_andi · 10 Dec 2009 at 21:28

I know what you mean, but this stuff does take some time to get right.

The reason 450x7.5 not working could be down to the higher RAM speed, but it could be down to the board not being able to run such a high FSb stably or the CPU hitting an FSB wall.

I suggest going back to your highest stable overclock so far (3GHz I believe), use the 800Mhz RAM, and increase the FSB 5-10MHz at a time - and running OCCT after each change. To save some time - only run OCCT for 10 minutes (just make sure you test the heck out of the overclock when you think you are finished).

paradisiac · 10 Dec 2009 at 21:37

well its been running OCCT for 15mins at 425x7.5 (3.18GHz) without issues so getting a bit closer to the 3.5GHz

trying it at 435x7.5 (3.26GHz) as 450x7.5 caused a 'windows cannot load, insert disc and run repair...' error. probably down to vcore but will see how this goes.

cmndr_andi · 10 Dec 2009 at 21:40

Sounds very good

Keep up the good work

paradisiac · 10 Dec 2009 at 21:42

be nice for another Q8300 owner to post up their results so i know whats sensible to aim for.

paradisiac · 10 Dec 2009 at 21:47

well it did 12mins ok at 3.26GHz maxing at 59 degs. what would you recommend i did now, 450x7.5 and upping the vcore from +0.075 to ?

paradisiac · 10 Dec 2009 at 21:55

tried 450x7.5 vcore +0.125 and still errors in OCCT

cmndr_andi · 10 Dec 2009 at 21:57

What Vcore does that give you in CPUZ at load and idle?

paradisiac · 10 Dec 2009 at 21:59

not sure, running OCCT on 440x7.5 vcore +0.075 and see how that goes. its not a temp thing as im not even hitting 60 deg yet, so maybe mobo, cpu or psu is at its limit, or i need to be braver with vcore

cmndr_andi · 10 Dec 2009 at 22:02

What does the Vcore say in OCCT then?

I ask, because I think the voltage shown in the BIOS is higher than the actual voltage. If so, then you can afford to put more voltage in.

paradisiac · 10 Dec 2009 at 22:04

because i have set it back down to +0.075 its showing 1.31, this looks pretty good so far, done 6mins with no errors at 3.30GHz

nope that just errored too

will up the vcore to +0.125 again and see what it says.

cmndr_andi · 10 Dec 2009 at 22:06

Shweet

With that voltage you can afford to use something like +0.15 V and still be perfectly safe

As for getting up to 450FSB, that may start being a motherboard limit. You may need to increase the Northbridge (FSB) voltage to keep it stable, though definitely just try the higher Vcore first.
