i know little about bottlenecking so, couls someone advise me if i am bottlenecked or not?

it's an i7 920 clocked tp 3.2 ghz and gpu in my sig.

got the ram sitting at ~1450mzh
 
Well what do you find it slow to do?
A bottleneck is something which slows down your overall system speed.
So where do you find the speed lacking?

In your setup the slowest component will be the hard drive. SSD will help, but only with certain things. New versions of SSDs on the horizon, might be worth waiting.
Personally I doubt your system is slow at anything, so any potential bottleneck is irrevelant. My system is clocked lower than yours and eats up anything I throw at it.

STALKER
all three of them.
playing these games is like trying to jog in treacle.
even with AA urned off and settings on medium.

my old system, a Q6600, radeon 4890 and 8gbs of ram performed better, 11fps better to be precise.
 
At the same res?
What driver versions are you using for the ATi?
Was it a completely fresh install?
Your current system should be no slower than your old one.
It should be flying along.

What settings are on your OC to achieve 3.4?
Wonder if you drop to a straight 3.2 and have the ram set to 1600 would that help. Multipliers should work directly, but it sounds like you have some error in GFX processing.

Definitely the same res?
 
this is a fresh install. my only startup apps are:
steam, catalyst & powerISO, which i've always have.

using catalyst 10.7 at the moment, though i've gone back as far as 10.4.
no difference really there.

the ram frequency is tied in some way, i can only swelect from a list of frequencies as opposed to punching in the numbers myself.

noticed a few stutters in Portal aswell, however, FEAR 2 performs flawlessly even at 2.8GHz.

to achieve my oc i'm basically just raising baseclock and then lowering the ram frequency (as it would automatically push itself up to 2400+ if i let it!)

i haven't touched any voltage settings except for bringing the ram up by 0.01v because it somehow slipped down to 1.64 and this ram is rated at 1.65.

edit: no overclock in catalyst, running stock which is 950/1200.
temps are all well within safe levels.

one simple test u can try.

reduce the graphics settings/resolution and compare the fps

if theres little difference between low and high settings, it means ur gpu is not struggling at the high settings, and the bottleneck will be elsewhere
 
i am using xms profile. cool, be nice to specify my own digits, i thought "unlocked" on the box was porkies, i'm new to clocking i7, used to core2 and memory strappings. cheers.

i'll try that cycrow, but last time i lowered the res on Clear Sky, the computer died and the monitor lost signal, i think the gfx overheated.
 
Might be why things are slow, is the ccc centre allowing your fans to run at auto, meaning at full speed when needed, the gpu might be throtteled due to overheating


I'd start invetsigations there, run furmark and watch the ccc and temps and fanspeed
 
well there appears to be no 'XMS' profile in existance on my motherboard, there's an XMP but if i disable that my bclk goes really wrong (have to set it to like 400 to get 3.4ghz)

tried setting my QPI to 5000 odd but it seems to default itself out to about 3006.

hit the ram up to 1700mhz and it's still alive so now i'm gonna download 3dmark and give that a blast.

wish me luck.
 
to OP .. try increasing the speed of your CPU because the GPU is still bound by instructions sent by the CPU so if there is still a significant increase in gaming performance when further CPU clocks are applied then there is still some head room for improvement. As soon the there is little gain in 3d permformance then you have hit the cards potential ceiling.
