Q8300 OC 3.2ghz Advice.

[KapiteinKoek007]

Hi all,
I recently purchased a intel q8300, cuz saidly my previous processor a C2D E8400 died in action after 3 years of intensive 3.8/4.0 ghz oc. i was a little bummed out, but i had it for 3.5 years so pretty nice processor lifetime.
Back to the subject @ matter; ocing the Q8300,
Im currently running it @ 3.3ghz 440fsb vcore 1.2875 @ idle 1.26 @ load 1.18
I also disabled all the powersaving options in the bios, except the multiplier, set to 7.5
so after 1 hour of occt 3.1.0 linpack testing 90 % mem the temps are around 50 the first core is always around 45/47 & the rest of the cores are constantly around 42/43.
My Cooling is a Corsair Hydro H50 With Push&Pull effect 2X120 mm 1600 rpm
i also have 2 tiny 40mm (i think) on the North/South Bridge heatsinks installed
Thats all clicked in on the Asus P5Q SE2.

So if my actual question is can i go higher, i heard on most boards 450FSB is pretty much the max, any higher and ur lucky.
so any advice is appreciated

looks like you can try for more oc and volts with those temps

Fill in your system specs.

Your P5Q SE2 should be able to get the bus speed upto around 480 maybe even 500mhz.
The main limiting factor is ram. I take it you have PC8500 yeah?

Anyway you need to get the ram frequency divider down to 1:1 if your going to have any chance of getting to above 450mhz.

The P5Q boards dont have a simple "DRam Frequency Divider" setting so to change the divider you will have to play around with the "FSB strap to north bridge" setting & the "DRAM Frequency"

I think you'll be ok the leave both them two settings on "AUTO" as the board will see the high bus speed & auto set the divider to 1:1 . But do a check with cpuz to make sure.

Leave the multiplier at the highest setting turn of the powersaving crap & also you will need to up the cpu core voltage 1.28v isnt enough to get a good overclock 1.4v is more like it. & last thing 2.1v is good for most PC8500 ram when over clocking.

Thanks for the advice, i have the vcore set @ 1.3250 in bios, and its stable, the fsb strap is set to 400 mhz, and the ratio is1:1 and no i have pc2 6400 unfortuately.

i have the same ship and cooling and ive researched this alot. the Q8300 is held back by its multiplyer (7.5) and max most ppl can get on them is 3.4/3.5 but some lucky ppl have gotten 3.6 on p5q and gigabyte boards max i had outa mine on 1.3v is 3.44 stable but i run mine at 3.3 24/7 @ 32c on the hottest core

440fsb is about as good as your going to get with PC6400 ram your already upto 880mhz. To get a higher oc your going to need PC8500

 

[newtekie1]

Your motherboard is going to limit you greatly.(I know, hear me out.)

The P5Q SE2 has a 4 Phase power design for the CPU, that is going to really hurt any serious overclocking with a quad-core processor.

Help Q9550 not stable even in 3.4(F..ing mad) Rea...

That is another recent thread from someone with a P5Q SE2, and they couldn't get it stable at 3.4GHz. The only solution was to get a new motherboard, and not surprisingly the new board allowed him to get much better clocks.

The 4 Phase CPU power on the P5Q SE2 simply will not provide stable enough power to allow good overclocking on a quad-core.

yeh ur right bout that, cuz when i go any higer then 450 it will not post, but when i put the fsb back to 440 it just posts and boots to windows with no probs.

 

[KapiteinKoek007]

Okay i got it @ 3339mhz and with 1 hour of prime95, the temps do not even reach 60, all around 55/56, i also run a 2 hour test with occt 3.1.0 linpack 90% mem and it was stable @ 1.200v (load) 1.250v (idle), also the temps did not exceed 58. unfortuately as mentioned earlier, i have pc2 6400 mem, so if i want to go higher the 445fsb i gotta have pc2 8500, but hey still a 33.5 % overclock not bad.
anyone suggestions what brand is the best in price/quality. like kingston, OCZ, Corsair ??

what ram do you have ? most 800mhz ram can oc past 900+

 

[KapiteinKoek007]

what ram do you have ? most 800mhz ram can oc past 900+

uhmm A-Data 2x2gb DDR2 800, i yeh i know its low budget, so oc potential is pretty low.
im planning to upgrade to pc2 8500 but im still figuring out what brand i sould go with, considering my budget is not that high.

 

[DOM]

well do you got a link to them ? the balistx i got where 300 new now there like 50 bucks

Most of the A-Data sets I guess could probably do 1000MHz if you pushed 2.0V through them and loosened the timings a notch.

uhm i got http://global.adata-group.com/en/product_show.php?ProductNo=AD2800U tis module X2.

Yeh i already set it @ 2.0v but i dont understand those timings, i do know they are @ 6-6-6-18-52-2, got it of CPU-Z

 

[newtekie1]

Can you get a screen shot of the memory and SPD tabs of CPU-z?

Yeh sure, here r the screens.

 

[Bo$$]

Try atleast 2.1v they can do 1000mhz if you set them loose enough

 

[newtekie1]

Ouch, already at 6-6-6 by default, that is already pretty freakin' loose already for DDR2.

You might be able to go higher by raising the voltage to 2.0-2.1v, but I wouldn't loose the timings anymore.

thanks for the info. i will up the mem voltage to 2.0 to start.
but wich way should i go; higher or lower?, i heard somewhere that the lower the timing the better.
i also have more timing settings on my mobo, like first information, second information, and third information.

the first informations are the timings with 6-6-6, should i adjust the other timings as wel?
the second and third are not making sense to me.
and can u explain exactly how those timings work, weirdly enough google doesnt make sense to me right now.

thanks in advance m8

 

[newtekie1]

Adjust the first information timings.

Lower timings give better performance. However, higher timings allow the RAM to run at a higher MHz, which is what you want to do. So leave them at 6-6-6, I wouldn't go higher than that, and lowering them would lower your overclock potential even further.
