| [memory] Asus P5N32-E SLI Problem
Can any one help my system is having some kind of performance problems. When i try and play latest games(CoD 4, Crysis) even at lowest settings(800x600) the are only running at 5-7FPS. Im sure u will agree my system should at
least be capable of runing even the latest games at medium(1200x1024), my specs E8500 3.16Ghz, Asus P5N32-E SLI, Asus EN9600GT 512Mb DDR3, 2Gb DDR2 Geil 533Mhz. I think it my be something to do with my memory timings but Geil.com were useless, CPU-Z reports the the DRAM frequency in the timmings section is only 277.3Mhz, this seems wron should it not be 533Mhz? I have latest bios(1405) and latest Nvidia drivers instaled. I include the CPU-Z reports. All Help Appresiated. andyturnbull2006@hotmail.co.uk |

What sticks out like a "sore thumb", is your FSB:DRAM ratio of 5:4.
1:1 is the only way to fly.
My setup:
Runs flawlessly.
You could probably "clone" my settings.

I ask because I've seen other folks say there is some sort of performance penalty not going 1:1, but no one has ever really spelled out what sort of penalty nor why.

| Simply put, a 5:4 ratio creates a variable-size "pile of bytes" that almost always experience a delay before they can proceed to the FSB. Even though the RAM can do things faster, the slower FSB speed is wat determines the throughput of the two.
Running "in sync", at 1:1, data does not have to wait for the other bus to cycle around.
I've found that running the FSB and RAM in sync alloes for twice the overclocking that I could attain with a mis-matched ratio. Also, things obviously ran faster.
I spent a whole day toying with the above setup. I scored each particular set of speeds with a video transcoding job that took about an hour to run at first, on default settings. My tweaks cut the time to 25 minutes.
For now, just try it. You'll see what I mean.
