Upgrade From 2400 Hd Agp To 7800 Gs Agp Slower Framerates

[gabefauver]

Yesterday I upgraded my video card from a visiontek hd 2400 agp 128bit 256mb to a 7800 gs 256bit 256mb evga and all my games Prototype in particular are much slower. Used driver cleaner and installed latest drivers for all. Any ideas?

Edit: The 7800GS is a hell lot faster than a 2400Pro my bad.

Just a question, why buy 7800GS when you can get a 4650/70?

 

[gabefauver]

yeah thats what I thought

thats what I thought too but it seems everything is much slower, except Oblivion which runs much better.

 

[gabefauver]

got it for free

What is your system set up?

 

[gabefauver]

k8ns pro, socket 754 sempron 3400+ @ 2.56ghz, 1gb ddr400, audigy se, antec 500w psu

The only explaination I can think of is your system is seriously bottlenecking the card.

Even back at those days, the 7800GS are used on systems with Athlon FX and P4 Extremes, but 1GB of ram seems awfully low for anything really.

 

[gabefauver]

It is the one that came with the case, which I got used. my bad it is a cooler master rsu-430

 

[gabefauver]

well I know it is lacking a bit but framerate was playable on prototype before and now it just takes a nose dive unless I am looking at the ground while moving around. tried oc'ing the gpu and it seemed to make things worse.

I just noticed that when opening a program my fans slow down for a brief moment. could the power supply be responsible?

 

[Zubasa]

Since you are certainly dealing with an old card, I really have no idea what condition it is in.
May be it is overheating?

40 degrees idle 42 degrees after 10 min of gaming

This seems rather old for even a 7800GS, is it a reference design?
I do not have a 7800GS, but I do have a X1950Pro from that same generation, the X1950ro loads at around 70, so I am wondering if it is your PSU causing the card to reset/slow down in games.

 

[gabefauver]

could I use a multimeter to monitor voltage while playing? if so how? Sorry to bother you with this.

Sorry for confusing you even more
You can try running HWmonitor while you play games, that should give you an indication.

 

[gabefauver]

ok I'll try it and post back in a few min. Thanks

 

[gabefauver]

ok here is the hw monitor info

the -12v and -5v are constantly changing from -3 to -11 weird

 

[Zubasa]

The -volts really doesn't matter much.
The -12V looks finem but the +5V looks rather interesting.
Do your card uses the 4-pin molex connector?

From what HWmonitor shows (if this sucker reads correctly), your +5V is dipping really low.
By any chance the the card might be drawing from the +5V rail.

Start from the obvious, may be you should check your AGP setting in the BIOS.

How about we start way back when you swapped out the ATI card for the Nvidia card.

Poor framrates can be caused by something as simple as not properly removing ALL the ATI drivers from the PC prior to installing the Nvidia GPU.

I say pull all your graphics drivers and use Ccleaner/drivercleaner in safe mode, then reboot and install an Nvidia driver of choice.

You are my saving grace, I feel like speaking crap at 4:30 AM may be I should catch up on some sleep.

Remember you can't always trust software voltage readings.

OP, I'd recommend grabbing driver sweeper and just cleaning out all the ATi video drivers that are possibly left, then installing the nvidia ones.

try Driver Sweeper (in safe mode only) and delete any nV ATI Driver from ur system .

Update: I just put in a brand new psu, no improvement.

Well I got a new thermaltake 430 watt psu still lagging and voltages read the same in HWMONITOR but bios shows different. Any other suggestions?

 

[sneekypeet]

have you tried cleaning your drivers out as suggested yet?

 

[gabefauver]

yep

Yes I used driver sweeper and removed all nvidia and ati drivers and reinstalled newest ones.
