Poor overclock ? - Poor performance

ojrules · 11 Jun 2009 at 21:08

I've got the following:

512mb 4850
e2180 @ 2.8
4gb 5300 mem

I'm playing at 1280x1024, and i'm noticing poor performance. In Dirt , on a track with other cars, offline im gettign around 25 fps, (settings maxed out, aa @ 2x ), in CSS everything s maxed out but im getting approx 60 fps... Is this to be expected or have i got a problem somewhere?... The overclock is very stable, no blue screens or crashes or anything since i clocked it ( a number of months ago) prime 95 stable etc, etc....

The one thing i did notcie was that the memory was really stuggling, and at its stock voltage i don't think i could push it much higher.. so could a poor overclock be causing poor performance, or is this not poor performance?....

You could try putting a few more volts to the ram and see if it will go any higher.
If the ram wont go much more it may be worth investing in a set of PC6400 to get more out of your system.
My e2180 will do 3.2Ghz on 1.32v so theres definatly more potential to be tapped there.

hmm i'm at 1.35v on my cpu atm .. and thats as high as i really wanted to go .. so yeh i may get some faster ram..

-- is this poor FPS from these games on these settings?

Id say its probbly about right, your video card is no doubt being held back by the processor.

would the extra jump to 3.2 make a lot of difference then?

Hi

Have you tried putting the divider on the memory, so its not run above its speed, then upping the fsb to its limit.

ojrules · 11 Jun 2009 at 22:08

erm... i dont exactly know what that means.. as i say it may be a poor overclock, stable but poor... here are my cpuz values :

Core speed: 2750
BUS speed: 275.8
FSB: 1103

Memory:
Frequencey 344.8
FSB

RAM 4:5
5,5,5,15,2t

FSBRAM 4:5 This is the divider you can change in the bios, to reduce memory speed
5,5,5,15,2t

My setting for 3.1ghz on akasa 965 cooler
Fsb 388, 8x multiplier
Ram at 1:1
vcore at 1.36875
Northbridge at stock volts

thanks ...hmm why the low multiplier?.. also am i right in thinking then that the ram is running at 388?

Mine is at 8, only because today got the new cooler and only had time to push it 100mhz so far. Should be up to 3.2 with fsb at 400, and 9xmulti by the weekend.
My ram is at 776, which is under its rated speed, coz it runs double to your fsb unless you use the divider.

Hope this makes sense!

thanks very much.. it kind of makes sense.. i'l have a fiddle after my last exam, and see if i can get up to 3.2..

wiggy · 11 Jun 2009 at 22:51

Glad to help, i'm sure it will go to 3.2. I also see your running 2xAA in your games, this can have a big impact on your fps, so try taking it out and see what difference it makes.

Ps dont forget to give us an update on how you get on.

I've had a look in the bios but i cant find specifically a divider, or ratio... the lowest i can seem to set my memory is 667 ... Should i keep the memory the same and fiddle with the FSB?..

EDIT- I tried 333fsb at a 1:1 ration, with the cpu multiplier at 9.. but it bluescreend before getting into windows..
- I've now put it at 330 at a 1:1 ratio,(2.97 ghz) cpu multiplier teh same, and its booted up.. just going to prime it in a sec....
EDIT- Was not prime stable... changed fsb to 320 ...
320 ran prime stable for 15 mins , no errors or anything, so that seems good.

temps were a little high for my likeing..:
System: 37
CPU: 67
Aux: 15 (?)
Cpu 0 : 57
Cpu 1 : 57

- hwoever idle temps are much lower : CPu 46, cpu 0,1 :35

One thing confused me though... : the voltage is set to 1.375 in the bios... cpuz reads 1.355 though, and the same with speed fan.. but under the stress test this voltage actually went down.... to 1.335

So i've only really gone from 2.75 to 2.88ghz, hardly fantastic, but i've noticed a slight increase in performance.. In Dirt the FPS are a lot more stable, - the minimum FPS has increased , which makes a clear difference, and the average fps is slightly higher... I'd still liek to know why voltage appears to drop during load, and i'm convinced the 120mm fan on the back of my pc is pointing the wrong way... but yeh for a little fiddle i think its been quite sucessful, and no horrible overclocks where i have to reset the cmos.... thanks very much.. any further advice would be great..
