View Full Version : More Ram, lower FPS.

Something to keep in mind when installing more memory. I had 2gb of DDR2-800mhz ram initially, added another 2gb to support 5 clients on 1 box and then discovered my fps was terrible. On further inspection I noticed the BIOS was set to auto-detect the ram speed which worked fine previosuly but with the added ram it was incorrectly detected at 667Mhz instead... manually set it to 800mhz and wam... practically doubled the frame rates. I never would have thought that 667mhz vs 800mhz would make that much of difference but it's like night and day. Noob lesson learned.

OMG I had the same thing. I went from 1 gig to 3 gigs of ddr2 and BAM, 1/3 fps i was getting (even when running only 1 client) and I get occasions where my FPS goes to 10 and doesnt budge at ALL.
I'm a bit of a computer noob and I was wondering if you could tell me how to adjust my settings to increase my FPS? (I have the same ram as you, just 1 gig less.)

Where the settings are will be different for each mainboard. Check the support website for your mainboard and see if there is a manual that shows you where the settings are in the BIOS for DDR ram frequency etc. Also the ram you added needs to be atleast as fast as what you got in there now, otherwise they all run at the slower speed from what I know (they should also be installed in pairs).

All the ram is the same speed.

Could it be that you bought Ram from diffirent Companys, so that the Timings and the Latency is diffirent to your old Ram?
Only the lowest Settings will be used with two diffirent modules, be sure that you not build it in in dual channel mode, check the Manual of you Mainboard for that.

If you use a 32-Bit System it will show you something about 3-3,5gb of Ram cause it canīt work with more than 4gb but also needs some Memory Addresses which are included in the 4gb,
with Vista 64bit you can use more than 4gb, but to really take effect you should build in 8gb of ram indeed, cause Vista 64bit need more Ressources.


Hope i got that all right, need a little more practice in englisch :D
have fun

If you want to check current DRAM frequency and a whole bunch of other stuff download 'cpuz' from www.cpuid.com. It will tell you everything about the memory chip timing and cpu, bus speed etc.
