Default Re: Typical core temperatures for 5900?

lol people have been doing this ever since the 5950 came out. the 5950 is a tiny bit better card, but thats all. it has slightly faster gpu and memory (the core has been redesigned, and the ram is 2.0ns instead of 2.2ns). but the benefits of flashing a 5900 to a 5950 are still very great. i should know, i did it myself.

some advantages are 1) my benchmark scores and gaming performance are pretty much in line with those that own real 5950 ultras 2) the bios allows for higher overclocks 3) cooler temps 4) better graphics

the only disadvantage is if you flash the wrong card (i.e. 5900xt) with 5950 clock speeds it could fry the memory.

Have you seen any benefits from doing this?

For all that matters, it is totally bios based. So all you need to do is flash your FX5900ultra card with a 5950u bios ----> and in your case try the Leadtek A380 bios first !

However, if you want best performance for your card, then you must also change memory Timing/Latency values in whatever bios you decide to use !

Everything you need for bios modding is here.

Things you will need;

1) BIOS ROM File - Leadtek A380U (5950U)
2) BIOS Editor - NiBiTor 1.8
3) Flash Utility - WFFlash 5.6
4) MS-DOS Bootdisk --> www.bootdisk.com

Happy modding!

Default Re: Typical core temperatures for 5900?

I just experienced similar problems with my ASUS 5900 card and I flashed it last night to a 5950.
Lower temps and higher benchmarks for certain (I'm on campus now. If you want details on what I did I can post them tonite, or you can email me).

It was scary but worth it. I have all the files you need (including my own backup .rom, but you will want to get your own).

Look around on the web and get a GOOD understanding of this process BEFORE you start. I had a backup card handy just in case. You should too.

The one thing I have had problems with is overclocking.
Both before the bios flash and after I get slooooow frame rates if I use coolbits.

I'm happy with the temps going down but just curious if anyone knows more.


BTW first time poster, long time (x2 days) reader LOL!
