GPU Bottleneck and CPU OCing Help

post #1 of 10
Thread Starter 
Hey everyone, sorry about the possibly noobish Question ;-)

I've had my current computer for two years now, and have recently installed a new graphics card, ATI x700Pro (AGP version), and in a previous post I found out that I'm having a bottleneck in my computer which is keeping me from getting the full benifits out of my agp card, most likely the CPU. I have an athlon xp2800+ and was wondering if overclocking the CPU would possibly solve, or help, my problem any.

when Running AM3 I got the results:

GPU: 6, 447
CPU: 3, 836

Those results were when I had my x700 OC'ed, but that only resulted in a score of 35k versus 34k when not OC'ed. I would think overclocking would yield greater results than 1k in AM3 unless a bottleneck was happening somewhere, but then again, that was the first time with a bench marking program.

Attached are the specs from CPU-Z. I have 2 sticks of ram, but they are identical, so I only included one screen shot of the ram.

Sorry to sound demanding, I don't mean to in anyway

Any guidance would also be great, especially if there is a post that describes my situation that I just havn't run into on the forums.

it won't bottleneck you that much.
what games do you play?
anyways, are those default clocks? and default voltage?

either way, change the cas latency to 3... and raise the fsb 3mhz or so at a time...
once it stops booting, raise the voltage a step and if it doesn't boot, raise it another step.
once you've gotten to where youd like to be then stop and stress test with prime95 and memtest.
also keep an eye on heat, and make sure its not too high before you start.
you're on stock cooling, so be careful.

Everything in the picture is default. Well I got the card for oblivion, because they didn't accept my old 128mb card. The game runs pretty good, but with near low settings. I was just hoping to get more of a performance out of the card, because it seems that other people are able to. Plus in another post a person made it sound like my CPU is holding me back

I also play Hl2, BF2...those typs of games.

also... in your system specs... ddr400 isn't pc2700, so you know. your ram is ddr333 it seems... also acceptable at tighter timings and lower frequency... as cpu-z says.
i don't have much experience with old systems... but just make sure you're temps aren't too high, and dont raise the voltage unless its unstable... voltage kills a cpu quicker, and raises temps MUCH more than frequency does.

overall it seems that that system is fairly balanced though... if i were you i'd mildly overclock it... and if it ends up that you can't then buy a new motherboard and cpu... that is, instead of better cooling.
overall as long as you don't lag in the game, then the system should be alright.

Well I'm not sure I feel safe OCing my CPU while running on stock cooling. I've been looking around for aftermarket coolers, such as typhoon, but have not made any purchases as of yet, with the addition of AS5 of course.

What are you explaining about the ram exactly? Just that I can purchase ddr400 if need be, since my Mobo supports it? Heh told ya I was new.

check your cpu temperatures. i believe speedfan will do so for you.
your ram might be rated ddr400... but its not running that fast.
for those games, i'd say get a new motherboard + cpu.
especially if you plan on playing quake 4 (which you should )

if your temps are good, then stock cooling might be all you'll need.

Heh the main reason for not getting a new pcu + mobo is that I just bought the x700 AGP :/ and new mobo's are equiped with pci-e. And theres no way around that

Right now idle temp is 25c, I'll have to run a game or something later on to check their load temps. Thanks for your fast help

use prime95 to check load temps. you need 100% cpu usage to know what the full load temps are.
25C is a very good temp though! depending on what your load temps look like, that should be very o/cable!

Your system stats say DDR400 PC2700. They aren't the same thing.

thats what i was telling him!
pc3200 = ddr400
