Crysis Benchmark: Q9550 CPU

CPU 2.83Ghz Stock
Best Average fps: 29.79
Min fps: 14.96
Max fps: 41.96

CPU 3.4Ghz Overclocked
Best Average fps: 29.69
Min. fps: 14.87
Max fps: 41.54


Help me out here guys. Shouldn't I be seeing a lot of improvement by OCing it from 2.8 to 3.4 or at least staying not decreasing? Why did my fps all go down when I overclocked it? GPU bottlenecking?

My Specs:
Quad Core Q9550 2.83GHz 1333Mhz 12MB cache 45nm
EVGA 8800GT 512MB Superclocked (Core 700, Mem 975)
4GB Corssair XMS2 DDR2 800 (4-4-4-12) 2.1 volts
EVGA 780i Mobo
700w OCZ GamerXStream PSU
320GB Hard drive 16MB cache 7200RPM
Sound Blaster Audigy SE
Windows XP 32-bit
 
You've punched up the speed of the CPU by increasing the FSB, which allows the CPU to communicate with the rest of the system at an increased rate. Your GPU may be getting those instructions sooner/faster, but it still puts out frames as fast as IT'S going to, which being "LAST YEARS MODEL", it's now behind the curve. The new chips from Nvidia and ATI slice and dice the 8800gt, a card I still currently use to good effect in most of the games I play. Pay and play for increased frame rates...

(yes, Elvis Costello still rules!)
 
Alright thanks guys. Anyone have an opinion on whats best out of the GX2 or the GTX 260 or GTX 280? I kind of want the 280, but way out of my budget right now, unless you know of a good deal.


P.S. anyone playing FSX with nice FPS on max?
 
Benchmarking Crysis requires many runs for an accurate assessment of framerate changes. I've seen one run be 4FPS on average slower than the previous run on my own machine. You're looking at margin of variation there, the difference is negligible. It just means you have another bottleneck somewhere as has already been mentioned.
 


Im playing on a 22in 1680x1050. Yeah its not bad, but when I saw it when I borrowed my friends 8800GT to run in SLI. Holly crap, amazing. I just thought I would notice more of a difference with cranking up my CPU. I guess I will after a new GPU. Flight Simulator is a big issue for me right now with frames.
 


CPU temps idle are about 41 degrees and while playing Crysis they only go up to about 47 tops. Never seen it higher for Crysis.
 


Hey Randomizer good to see you again, long time. Are you currently playing FSX? I went from a e6600 Dual core to a Q9550 and barely noticed a difference. Maybe by 10% if that. I was shocked. I can only hope maybe a new GPU combined with my new CPU will make a difference. If not, I give up on that game. If you are playing it how are your frames, settings, and specs?
 
Hey whats a good program for temperatures. I just had very bad luck with Nvidia's System Tools and nTune. Not working for me and cause instability and crashes. Anyone using a good one out there?
 

I don't own FSX, but I have seen that it likes more cores. It's a ridiculous game really. If you check out the VGA charts, many of the cards perform about the same.
 


Have you seen a chart for FSX or are you just speaking in general?
 


30 FPS is not very playable, because that is an average FPS not the 15FPS it dips down to. Usually an average FPS should be a minimum of 45 or higher.

In the meantime (before buying a new video card), the OP might consider turning down eyecandy to regain higher framerate.

Spitfire, you're still barking up the wrong tree. CPU is not very important in modern gaming, because CPU gains tend to be above the level of playable framerates, within the realm of whether you have 50+ FPS or 80+ which doesn't matter, and only then when it was mismatched with a less powerful GPU. It will be that way for quite a while because game developers target typical aging systems and the adjustments for performance tend to be mostly about how fast the video card is, at least until we have extensive host-processed physics but video cards are doing that now too so it seems we have left the era where a modern low-mid to midrange CPU is a factor in having playable framerates.
 


if money is no object i would get a 4870x2 easily the fastest card out unless you really want a nvidia card then go for a 280 GTX but when you do get them keep you CPU oc'd as it could bottle neck your new card.
 
Hi Spitfire

From what I can see no one really answed your question ...you havent mentioned any detailed bios settings but my guess is that you just raised the fsb without doing much tweaking elsewhere...Im also guessing your fsb strap is set to auto so when you change the fsb speed the fsb strap changes its timings and speed to keep the system stable....If Im right this is why you didnt get any more perfomance even though your clock speeds are higher

hope this helps 😉
 


Hey FSBUZZ,

I pretty much increased the FSB from 1333 @ 2.83 to 1600 @ 3.4. Then I increased the CPU voltage to about 1.3. What else do I need to do so that I will see a performance increase? I thought that was about it. When I overclocked my e6600 doing it like that from 2.4 to 3.2 I did notice a difference.

In your opinion should I keep my Q9550 or send it back and get the E8600. I mostly only play games and internet surf. Some music recording in windows. What do you think?
 
I would keep the q5500 and try to get your ram running a bit faster... try to get the fsb and ram to 450 1:1 ratio and see what happens.. might have to tweak voltages a bit but every system is different so you just have to experiment.. good luck :)
 


If I get it up to 450 at 1:1 does that mean I will be increasing my 800 speed ram up higher?

What do I increase the voltages up to?
 
So I have a few questions. So I need to go to the CPU config section in BIOS and select

1:1
FSB 1600 MHz
Mem Mhz 1400 ( I didnt know that you can increase your ram speed.) I have DDR2 800. Will that hurt it?

What should I make the voltages?
