GPU running half of clock speed

I'm just curious about this. I was told on another forum not to worry about the card unless there's visible artifacts.

Also been told by some that GPUs almost never run full potential in Windows and not to expect otherwise. Not sure what to believe at this point.




Also used GPUz and never see anymore than about 5% of VRAM being used, even under full load gaming.

Currently running @1280x1024 75Hz refresh, OS is Windows XP Pro SP3.


System specs:

AOpen MX4SGI-4DN2 mobo

Pentium 4 Prescott (SL7E6) 3.4GHz/1M/800FSB (socket 478)

PC Power and Cooling Turbo Cool 860 PSU (860 watt single 12v rail)

EVGA GeForce 7800GS CO AGP 8X 256MB

3GB DDR400 (2x 1GB OCZ Performance + 2x 512MB Samsung - running dual channel @ 2.5v 3-3-3-8)

Seagate Barracuda ES 250GB SATAII HDD 7200rpm 16MB buffer


NO overclocking, mobo seems to undervolt CPU (1.30v idle and about 1.22v under load) but it was designed for Northwood core CPU.. Prescott is detected due to BIOS flash. I do also have a Northwood core CPU (SL6WJ) 2.8GHz/512k/800FSB

I was able to find a newer video BIOS for this card but hesitant to flash since I don't want to render the card useless.


Do I just ignore this? Or something I can do so that it will run at full clock speed and use more of the on card VRAM instead of it hogging all my system RAM?

it is ok, i do not know more than you about that lonely topic so i can't comment. I do know that GPU memory plays see-saw with system ram in 32 bit platforms ~ something to the tune of memory addresses swapping. Other than that,  it seems you know more than I do on that one.



It happens sometimes, i remember i had a lonely topic about a gfx card installation a year and a half ago, i think after 48 hours a gentle "bump" is ok to keep the topic current as it may be getting ignored for more current novice type topics.

Few, if any, topcs are ignored...you can tell that if you look at the number of reads/views for any topic.


Sometimes...there just isn't an answer to what is asked...or those who might have an answer...did not view the topic.


It takes a combination of circumstances...for a good result...one of those circumstances is understanding that members are not all-knowing or omnipresent :).

OK, hope this helps with system specs.





















CPU cooler is a Scythe, but I don't remember which model it is. And if it helps any, here's what Speedfan 4.49 shows for voltages and temps.
