1900xt core and memory clock questions

[Vokofpolisiekar]

I don't think that you should return the card. If I look at my 3dmark03 score, then I'm not too far off as in 3dmark05. I quess that 05/06 is very dependent on CPU power along with memory sub system. Strangely, my 06 scores are good if I factor in my 3.2Ghz CPU (4900 @ 3.2 / 5000 @ 3.4 and 5100 at 3.6).

Still don't know why 05 gives me this crap - but who cares, all my gaming benchmarks are pretty close to what one can find on internet benchmarks!

ATI tools doesnt work with the X1800XT and up due to the seperate 2d/3d clocks, use this one:

It works best by using ATI tool to set the voltages, then overclocking the 2D, not 3D clocks in Overclocker. It reverts to normal with each reset, so if your system crashes, resseting should bring it back.

I managed to get my X1800XT to 729/846 using the combo of voltage modding in ATI tool and OC'ing in overclocker.

Check this for more thorough info on overclocking the X1800XT.

Personally I dont like screwing around with the Voltages, basicly coz i dont know where the danger areas are and where to stop.

Like vokofpoliesiekar, I live in South Africa and Money is an object for me, and yes I almost spent 3/4 of my salary last month on this X1900XTX card.

And a warranty is my best friend, but if im assured of the voltages that can be set, then I will go into the voltages and set them for OC'ing.


So any of you guys have tips and stuff, ratio's , setttings what eva.

I would like to know them 😀

O Yeah, I got 4822 in 3Dmark2006 @ standard Clock and MEM settings.

I get envious to see other ppl score more than me, thats why i wanna over clock.

My old athlon I OC from 2400 to a 3200, that was the fastest chip I had for ten minutes 😀

JKS!!!!

It ran fine in windows but bombed out in when playing games so i set it too 2800 and it ran stabble.


And dont even get me started on my old Pentium II 300A chipset that baby
could move mountains 😛

ATI tool gives you a warning when you set the Volts to high. For the mem volts, the warning kicks in at 2.25v, hence I stopped there with 846mhz untill I confirm whether or not I have 1.1ns ram and research how many volts it can take. Im not sure about the core, It wont run at 729mhz with an extra .2 volts, so im leaving it at 700mhz on stock which runs fine. Just hoping I can somehow squeeze 900mhz out of the ram without killing it.
