How Well Does Your x1950p OC ? ... updated

You might find it marginally worth it? A few fps in a marginal zone is often the difference between playable and unplayable

less than marginally worth it

my CPU has a *real* OC ... from 1.8Ghz to 2.81Ghz ... with *noticeable* performance increases

OTOH, the x1950p manages to go from 580 to 608 on the core and scores +200 marks in 10K ... or +2% "performance gain"

after dealing with Sapphire's Brain-Dead RMA people, i would not want to take *any chance* -- for only 2 percent - of encountering them again
[although that would *force* an upgrade to GTX or HD-XT]
:Q

so far ... *nothing* with my x1950p is "marginal" ... it runs STALKER with *everything* absolutely maxed in game over 30 FPS ...

letsee +2% might give me +0.5 FPS increase ... if it isn't already limited by my CPU
i won't get ANY more "details"

NOT "worth it" - imo

i'd rather OC my CPU further - or lower details

-OR

much better

buy a NEW GPU when i am dissatisfied with my current one
============

and Paratus, yes, your CPU does hold you back ...
however, if you OC your CPU or GPU too much - at the "edge" of instability -
you 3DMarkXX score may go down

i OC'd my CPU beyond stability ... and got a lower 3DMark06 score ... that's when i *settled* on 2.81Ghz for my e4300 ... i can get much higher with a better MB

Just wanted to chime in that my Sapphire x1950pro does not overclock using the CCC Overdrive utility. I'm getting the exact same scenario that you have described.

=(

Edit: AGP

I've been hearing that the X1950 Pro is a highly clocked GT w/o the OC headroom, and, if you go to gpureview.com, the specs are basically identical except for clock speeds. Disappointing, huh? My 7900 GTO has basically the same relationship to the 7900 GT.



EDIT: Doesn't overdrive work? That should be better than +1 MHz. And what about GPU/mem voltages in ATITool?

We'll see what happens with that HD-2900XT though.

Bear in mind that the Radeon X1900GT is based on the R580 (X1900XT) and the X1950PRO is based on a new and less power hungry core, the RV570 which is based on a 80nm (Kinda budget process like the 110nm) process compared to the X1900GT which is based on a 90nm process which has higher quality components inside and is able to run at higher speeds and consumes far more power.

The Radeon X1950PRO phisically doesn't have the missing 4 pixel pipelines and the 12 pixel shaders, which the X1900GT has but they're disabled by default. The X1950GT is also based on the X1950PRO core, like the X1650XT.
