here are my current specs(will be upgrading soon)

mobo: biostar ta 790gx 128m
cpu:p henom x4 9950 oc to 3ghz
ram: 5 gigs crucial ddr2
gpu: currently hd 4850 ( i bought a 6850 and my psu is too weak for it. will be buying a 750 watt ocz soon)
psu: thermaltake tr2 550 watt

i moniter my cpu and ram usage playing bf3. i usual get between 60 and 70 % cpu and 70 to 75% ram usage.

i want to know if adding more ram will
1. make my cpu usage go down
2. help my fps.
3.help overall system performance. ( at desktop i use about 26% ram and 0 cpu)

Thanks :)

Using 2x2GB and 2x 512MB?
What RAM are you using?

1. No
2. Probably not.
3. Not for basic gaming. Possibly yes, for heavy multi-tasking.

thanks for the reply!
is 70 % cpu usage bad? what about 70% ram? so ur saying if i add more ram i wont get any better performance than i am now? cuz before i had 2 gigs and things were horrilbly slow, especially bf3. stuttering frames all the time. i added more ram and the frame rate went from like 20 to 40

The 2Gb you had before wasn't enough to run it smoothly, adding more helped because the program could use more, but once you have enough RAM adding more won't effect performance because the program won't utilize any more than it needs. I highly doubt adding more RAM will improve performance at this point.

Your CPU usage is fine, BF3 does a good job using multiple cores and will push any quad core to near 100% usage, especially in a 64 player game.

Right now a better video card is your best bet for improved performance.

Check your MB manual. I don't think that's an approved combination.
Should be matched pairs.

ok thanks for all the info! i really want to use my 6850 but my psu is too weak. the card spins up full speed and does nothing else. i have a 550 watt psu and its pretty old and from what people tell me it was never really good

Looks like your best performance boost options is a new PSU and run that HD 6850.

Hop over in the Memory section of the forum and ask them about your motherboard and that non-standard 3x1GB & 1x2GB RAM.

RAM:
Yes, you need PAIRS of RAM. If you don't then your RAM operates at half speed which actually might not make a difference for you anyway. Still, I recommend you go with pairs. Be warned though if you mix RAM you may have issues. My advice is get a new 2x2GB kit for about $60 at NCIX and sell/give away your existing RAM.

Always run MEMTEST after adding RAM or modifying the CPU or RAM settings.

RAM and FPS:
4GB is sufficient for gaming with your setup and more will provide you no benefit.

CPU usage:
"I want my CPU usage to go down"
Uh, you can't unless you lower the quality of the game.

The fact that your CPU usage hits 75% also means you can't buy a significantly better graphics card. If you got a slightly better graphics card your CPU would go up as well. If you got a MUCH better graphics card your CPU would simply become a bottleneck and the graphics card couldn't use its full potential.

CPU heatsink:
I'm guessing noise is an issue the way you discuss it. Get a better HSF for your CPU. It has to match your motherboard socket type.

Check out NCIX. http://us.ncix.com/products/?sku=41337&vpn=RR-B10-212P-...

I think this HSF is compatible.
(don't forget fan control in BIOS to vary fan speed. may need to set to VOLTAGE)

When memory configuration is matched on both channels, both channels are paired up to double RAM bandwidth. When the configuration is asymmetrical, both channels are operated independently and end up with only half as much usable bandwidth when reads/writes are occurring within address ranges that tend to hit only one channel at a time.

Asymmetrical configurations work but with degraded memory performance most of the time. How badly this may affect performance depends on how (un)evenly balanced accesses between the two channels end up being and how many extra pipeline stalls the slower bursts might cause.

ok thanks for ur help. so i have a phenom 9950 at 3 ghz. i have a 4850 gpu now. would a 6850 be really over doing it?

You already own it, so use it.
I just updated my post.

If your CPU is a bottleneck (and it varies by game) your CPU usage will hit 100%.

It's not always certain because games can't always use all of your cores fully. If you hit 100% on two cores and are high on the other ones you're getting pretty bottlenecked.

It was easy to tell on single core CPU's where you stood.

Okay, I reread this post and let me summarize:

1) get 2x2GB of RAM and don't mix types

2) get a CPU HSF if your current one is stock (for noise/overclocking)
3) get that power supply

4) install your HD6850


sounds good thanks! im running mem test now. i feel bad going from 5 gigs to 4 gigs though. maybe just a mental thing lol

ok that makes sense. i moniter all cores playing various games and the most i ever hit was 80% that was bf3 running high settings and explosions all around and 64 ppl in the game

You can do 2x2GB + 2x1GB, just need to make sure each DIMM from each matching pair is in the matching position on each channel to enable normal dual-channel operation. Usually this means one matched DIMM pair in the first two slots and the other in the next two.
