ATI Radeon X1800 XT's now from £199 at OcUK

Got my one yesterday :) and installed it along with my new Mobo.
According to ATI Tool, it seems to default at 593/697 sort of speed, is this normal as I though it was supposed to be 625/750. Does it run at different speeds in 2D and 3D operation.

I ran at stock speed on the X1800 and got 16,500 odd on 3DMark2003 and 31,500 odd on 3DMark2001SE.

I used ATI Tool to find the maximum core speed, which started artifacting at about 639. I upped the vcore voltage in ATI Tool, to 1.4v and it would get as high as 680 on the core. With a bit of a bump on the memory, that went up to 880 before artifacting.

Can anyone tell me what is the safe limit for the vcore and memory voltage on these cards and at what temperature I should start to worry (Its been up to high 70's already).

Great card and great deal, cheers OcUK.

Core voltage wise, it's fine to go for the full 1.575v for when you're benching, but i wouldn't suggest running this voltage 24/7 or extended periods of time. The memory actually benefits from you not increasing the voltage, but even slightly undervolting it. By undervolting mine to 1.996v i've managed to get 930mhz on the core, which is a stunning clock :)

Cheers, I will have a play tonight.
I will probably run at stock after I have run the initial benchmarking, as at the resolution I will be running, it will be more than sufficient to get decent FPS with everything turned up max.

I've set ATi tool to run at startup and to load my Gaming profile. This means every time i boot the PC it sets the clocks of 720/850 on my card. It gives a noticable increase in performance in games, and i'd definately reccomend doing this :)
 
hang on..... I should be getting my one today...

Can you increase the volts on both memory and core with ATI tool?

WOW, those XTS are amazing prices.

Try and get the XL down a bit now :D
 
Can I still use a simple program called Reforce to set my refresh rates to what i have? 120hz for 1024x768, 85hz for 1280x1024 and 75hz for 1600x1200?

First, I was going to spend £190 on a 7800GT, then I saw this 256MB XT and now you show me the 512MB... jeez. You should have some kind of goverment health warning on this site.
 
theres prob been loads of threads about this but whats the safe volts you can push in to these cards on both core and mem?

Cheers

It's not that bad anymore. Despite all the moaning, it only uses about 4MB RAM with .NET 1.1 and 2.0 installed and isn't really buggy anymore. It's quite easy to use also - I know, 'heresy!!!', but true - however it does hinder overclocking as it doesn't allow you to overclock without difficulty so hmmm.... I forgot about that. You should be able to use something like that - ATi Tray Tools should have it.
