O/C'ing & ram

July 11, 2009 at 09:54:33
Specs: Windows Vista, 3gb
i thought it was about time i started to see what my processor could do.

ive currently managed to go from 2.3ghz to 2.8ghz with no problems so far, and a top temperature on prime of 54°.

specs are:
core 2 duo E6550 with cooler master gemini w/o fans
Gigabyte G31M-2SL m/b
3Gb PC6400 Ram
XFX geforce 9800 GTX

here's a screenie of cpu-z & temp: http://i32.tinypic.com/ilghfp.png

i've been increasing the fsb by 10mhz at a time, with my ram set to 1:1

how far could this processor go, and should i try and o/c my ram timings too?

thanks

also, ive just noticed, my memory has went from 5-5-5-15, to 6-6-6-19.

is this good or bad or do i need to adjust this too?

The motherboard & RAM are the determining factors. You *should* be able to get the CPU over 3.0GHz. Remember: the faster the FSB, the faster the system.

Try lowering the CPU multi to 6x, then see if you can bump up the CPU frequency (in increments) to 500MHz. The board or RAM may squawk somewhere along the way...if that happens, you'll have to find out which is causing the problem & see if you can work around it. Either that or lower the freq to a point where the system was still stable, then experiment with the multiplier. Let's say you can't hit 500MHz but you find it's perfectly stable as 475MHz. Try raising the multi to 6.5x & see if it will run at 3.088GHz.

Don't rush thru it...be slow & methodic. Test for stability often. And as always, you *may* have to increase the CPU voltage (possibly the chipset & RAM too) to stabilize the overclock.

thanks jam, ill give the multiplier a go, though i only have 2 options, 6 or 7.

as for the ram, any ideas why the timings have changed, and if they are better or worse since the o/c?

ok...

when i set the multiplier to 6x with 410mhz, i get 3 short beeps and then a further 1 beep, so i lowered back to 400mhz. same happens with 7x multiplier at the same speed.

i have my system set to automatically control the vcore, should i manually increase this or leave it as it is?

You didn't post a screenshot of the CPUZ SPD timings so I can't answer for sure, but if your RAM was running at 5-5-5 when it was underclocked & now it's running at 6-6-6 at it's default speed (or higher), that's normal. Take a look under the SPD tab & see what the timings are at the various speeds. You should be manually controlling the timings & voltages anyway.
