Effect of RAM freq. on CSS FPS tested

post #1 of 10
Thread Starter 
I tested what effect the RAM frequency would have in the stress test, and discovered it could well be part of the bottleneck along with CPU.
I ran each test twice and under the same conditions:
550+Megs of RAM free
256 meg Heapsize
fps_max 300
steam.exe set to low priority
hl2.exe set to high priority
hyper threading off (turning it off improves your frame rate btw)
EIST off
TM2 off
C1E off

My relative system specs are: FSB 211x18(3.8GHz) Corsair 2x512MB Twin 8000UL RAM @ Dual channel. (this RAM is capable of running at 1Ghz)
I will start with my results under stock frequency wich at the time was 3.33x211 (702MHz)
154.17 fps average
153.98 fps average
Now with just a slightly higher freq 844Mhz (5-5-5-15)
158.48 fps average
158.55 fps average

Keep in mind these figures also affected the FPS's lows too, not just the highs.

Now to confirm that the RAM did indeed make a difrence, I ran the test with the lowest freq I could get, wich was 316Mhz (4-3-3-9)
135.31 fps average
134.41 fps average

Good job Mafioso

what is your cpu again? iNTEL? cuz I find it extremely hard to believe you are getting that high fps with an intel...

Dude I honestly don't understand why you are laughing cuz my fps is crap in CSS with an intel processor...look at these specs:

Intel 3.2 ghz with HT
1 gigddr2 ram (4-4-4-12) latency
p5ad2-deluxe motherboard
xfx 7900GT (450/660)
160gb

I get about 115-120 fps in stress test and during game about 50-100 fps...during firefights it will drop to low 40s.

First of all; that's no 955X chipset. There's a big difference between 3.2ghz and 3.8ghz. The 7800 GTX could be way overclock than your stock GT (?).

Considering I have a XFX video card that I highly doubt that is true. These cards are good overclockers. I have a 925X chipset so I still cannot fathom the 35-40 fps difference. Overclocking your video card in CS:S has literally no bearing on the video stress test results; at least in my situation. I can overclock my cpu to 3.6 ghz and cannot see any improvement in the vst. I'm left scratching my head..... : (

btw...the creater of this thread states that turning off HT improves fps...for some reason I don't see any improvement : (

I never had any confident in the new 925x and 925XE chipsets, that's why I didn't get one in the beginning. It was shown that going from 875P to 925X didn't had any considerable change in performance.

I made a little mistake because I didn't want to buy a expensive MoBo and ended up getting a 915P ABIT and performance wise it was good but not to my standards, so I only used that system (now my 2nd rig) for about 2 months and then I saw the difference between 875P and 955X.

Chipset alone may not entirely give a performance boost but there are also features that the MoBo manufacturer puts in the BIOS which end up gaining a few extra points over MoBo brand "X" to MoBo brand "Y". I have features in my 955X ASUS that I've never seen before in another motherboard.

Overclocking always help. Always!

Nightrider honestly there is literally no way you could not see an increase in performance with your CPU overclocked from 3.2 to 3.6 unless you are doing something very wrong. Also I know for a fact that the FPS that Mafioso posted are possible just to assuage any doubts that you may have.

it depends on resolution and settings you are running but MaFi0s0 should get higher tahn your setup with 3.8ghz and a newchipset
