is the ram holding me back? overlocking e6550 question

post #1 of 4

Hi, i recently bought BF3 for pc and i want to overclock my system, since i am experiencing pauses at times. The pauses occur specially when using fraps, however avg fps is 50 fps. here is my spec:

In the bios i managed to bump cpu frquency to 3ghz from 2.33. however DDR2 timings were also bumped to 856mhz. i'm not too pleased about this, because i remember overlcoking ram made my system unstable once. i cannot further reduce FSB:RAM ratio as it is already at 1:1. here are my overlcoking specs so far:





so, is it safe for me to bump my frequency to 3.2ghz without sacrificing stability and reliability, since it will increase my ram clock way beyond factory settings? could i go higher? should i bump ram power? with current overclock i sometimes experience slight lag/pauses, it's not perfectly smooth. i'm not sure what causes the sudden lags (happens ever 20-30 sec) but im guessing either cpu or harddrive. the strange thing is during lags fraps reports fps at health 45-50. i have updated all drivers.

cpu useage with fraps


cpu useage without fraps

Well your cpu even overclocked 3.2ghz does not have the power to run fraps and bf3 at the same time. I would never overvolt ram, if you do that your going to be out some money since ddr2 is actually more expensive than ddr3 now. If you look at your e6550 it's running at almost 100% during the game which tells me you have hit the limit for your system. I'm not sure what resolution your running but it must be pretty low with all settings on medium. The lags are from your cpu my friend, sorry.

a couple of things.

its never a good idea to run different brands of ram together.
you have "4GB (4x1GB) Ocz & patrio DDR2 OC'ed to 858mhz"
this is usually a recipe for disaster.
and running 4 sticks of ram is always harder on an overclock than 2 sticks.
you will need to raise the NB (northbridge or mch) voltage a few levels

always, always buy matched pairs.

also

"i cannot further reduce FSB:RAM ratio as it is already at 1:1. here are my overlcoking specs so far:"

this is wrong. there is always a way to unlink the ram, so it does not run at 1:1
go back into the bios, and in the ram multiplier, change the multi until the ram is at or near stock speed. 800mhz

i can run BF3 on high, and i have 100% cpu usage across all 4 cores, so a dual core will struggle, no matter how high you get it

Ok so I decided to upgrade my CPU and hence replaced my dual core with q6600 quad core CPU. Right now all my clocks are at stuck level. My only problem is that since the upgrade my fsb to ram ratio is only limited to 2 choice 1:1.25 and 1:1.50. I used to be able to select 1:1 with my e6550, this way I could overclock only CPU and FSB without doing ram. What am I missing?
