X800xl overclock

[wallrunnerm15]

i have the powercolor one with the pci-e power connector. it is at 480/500 stock. but since i added a vf700 alcu i have been able to get 520/530 stable. is there anything i can do, especially to cool te gpu ram? thanks.

ramsinks?

X800XL aren't great oc ...

As has been mentioned before, the X800 XL series does not tend to overclock well.

520/530 is pretty good.
Consider that a x800xt pe is only 520/560 with the same 16 pipes.

is an arctic cooler better at cooling the zalman??

The Zalman is better, but it's not worth it for the X800XL, like others said, it does not OC well.

QFT. The zalman is VERY good on teh 6600GT though!! 590/1200 rock solid. I'm going to shoot for 592/1210 tonight!

Well I guess you can do some volt mods to get a few more MHz. As for cooling, H2O?

If you wanna overclock so badly buy a 6800GT, flash to Ultra and go from there.

 

[wallrunnerm15]

in isn't that, but i would like to squeeze out any ounce i can out of my xl. also how much of a benefit is added by increasing voltage and/or increasing the bandwith from 100mHz to maybe 110mHz in the BIOS?

 

[mOeeOm]

I heard increasing it to 105mhz helps the x800xl overclock better.

 

[Unkno]

wow, that's a VERY good overclock for the X800XL (BBA), average/near highest overclocks at stock are at 450 for the core

Check out my X800XL OC in my Sig

I found that the memory on the X800XL seems to make a bigger impact on the FPS performance in most games. My OC was similar to yours but after some experimenting I dropped the core some and cranked up the Memory. I saw a much biggger increase in real world FPS as well as in benchmarks.

I guess with X800XLs its just kind of a hit or miss thing about the overclocking. Most people don't get there X800XLs near what the OP and I have reached. I guess we're just lucky.

(and yeah I know the 6800gt OC's better)

To paraphrase Star Trek: "We can't do it captain! We just don't have the power!". :Q

Essentially, you're SOL. If you try a volt mod or watercooling you're insane IMO. Your card is FINE. It's within 25% of the fastest out there. What more do you want?

Edit: I predict that your card will experience a hull breach (read: your PCB will rupture) and will also have a core meltdown if you try to overclock using the above-mentionned means.

Have a great night. And drink beer; it helps you write things like this. :beer:

I get the exact same OC numbers you do with my X800XL and AC Silencer. My 3dMark was actually one point better too. I also joined these forums 2 days after you.. soul mate?? haha. I couldn't believe the difference I got from the stock fan, idle temp dropped 8 degrees and never gets hotter then 50C. Not to mention the 430 to 450 core and 550 to 575 memory OC numbers... Quake 4 plays much smoother at 1280x1024 now. Screw Zalman and those who say you can't OC an 800XL.. AC cooling 4life!
