Default Re: Basic FX59xxx bios changes

Hi jimmor,

I have MSI NBOX FX 5900 Ultra (2 heatsinks (with 2 fans) covers both: GPU + mem. I have been using cool bits but every time I reboot my box (XP Pro) the 3D speeds are reset. I have been doing testing for a while now and it seems I can clock my card to 470/900 and all my games work well. If I clock my card to 470/950 almost all games work well except IL2:Forgotten Battles flight sim. In about 30 minutes my computer locks up, this seems to indicate to my that this flight sim stresses my video card hard and after a while the card locks up. 470/900 seems very stable however. I would like to modify my current bios settings to 470/900, what tools should I use to modify my bios ?

Thanks for your help!

PS: I'm a bit surprised that my video card can't take 950Mhz for memory as the NBOX version was a bit pricey compared to other 5900 Ultra. The heat sinks are copper (2) and are very heavy, I figured I could take this card to 475/950 quite easily, oh well I use Thermaltake 5000A case and CPU is very cool running at 44'C (AMD XP 2700+ overclocked to 2304Mhz) so I don't believe I have case cooling problem.

Not sure I know if and how a NBOX FX5900U differs from a normal FX5900U ???

Have you tried flashing your card with a 5950u bios ?? Only reason I ask is because, my Aopen 5900nu couldn't overclock to 475/950 until flashed with a 5950u bios !! It was the extra GPU volts and different memory timings of a 5950u bios that allows it to currently run 500/1000 ! Can run higher, but I prefer to stay at current levels as insurance against unknown and because my stock heatsinking is not as good as a 5950u's !!

Your 5900u has the same GPU and 2.2ns memory chips that are on my card, so a 5950u bios should do same for you ???

However at the very least, you should modify your bios for both increased GPU volts, and improved memory latency ! After bios mod, overclock GPU to new higher stable speed, then modify bios to set as stock, new tested GPU/Memory speeds !

To modify and save new bios, you must use Hex editor of Ray Adams X-Bios editor ! Download it from Guru3D, and modify the bios using my Guide at first post of thread !!!

This is just a guesstimate on my part, since I don't know what the rest of your setup is like, or what criteria you were using to measure performance improvement ??

Also when measuring performance improvement from your card, it is best to stick to programs like 3dmark03, and aquamark3 and codecreatures1; good graphics card tests !! And use programs like 3dmark01 as a guage of overall performance changes ?? It is also most important to use same known and stable driver, like 53.03, for all testing otherwise it will be almost impossible to separate driver and card perceived performance issues ??

And you should try another 5950u bios, but don't worry about VIVO problems untill satisfied that another bios is going to give more than your original ??

I actually tried the Gigabyte 5950u bios, but found it average, and definately not in my top 10 ! However every card is different, so try the MSI that I use and the BFG and even the Leadtek, or anything else you fancy ? When and if you find a better bios, you may also find the new bios also provides the VIVO output you require ? Always remember a lot of 5950u cards provide very similar facilities !!!

my only other suggestion, is to modify your original bios with the "40" latency change as indicated in my 59xx bios modding Guide at first post of thread ! It will improve your cards memory bandwidth !!

Hey thanks, my current setup looks like this, P4 3.2c @ 3.66 ghz (229fsb), IC7-Max3 mobo, Kingston HyperX PC 3700 @ 1:1 3-4-3-8, SoundBlaster Live! 5.1 Thermaltake 480watt PSU with PFC, i did change the latency to the indicated 40. I think I will try to use a few different BIOS's but i would like to know if it is possible to change it to work with my VIVO, one last question, do i need to change the vendor before I flash it or do i leave the vendor the same?

Same here...I would have to get MSI NBOX FX5950U bios before I even consider flashing.I'm very much happy with what I currently have I just would like to speed it up a bit...

No I haven't tried flashing, I need to find MSI NBOX FX5950U bios first - so far no luck.

How do you know mine has 2.2ns ? I guess I will need to find out what memory chips are on FX5950U, do you know ?

Will Ray Adam's X-Buos editor tell me all the specs for my card and what I need to modify on FX5900U in order to get FX5950U ?

You see I want to be very careful as I love my FX5900U very much I don't want destroy it just to get few FPS out of it (there isn't much difference between FX5900U and FX5950U).

PS: I will check out your guide thanks!

your setup actually looks very good, so not sure what I would suggest as worst bottleneck to cards performance ???

For flashing, use nvflash.exe v4.41,

nvflash -r (just removes any read-only restrictions)

nvflash -b origbios.rom (saves original bios)

nvflash -u -p biosname.rom (flashes new bios)

Only important thing to note, Because of DOS restrictions, "origbios.rom" and "biosname.rom" must have max of 8 char's in first part of filename and max 3 char's in extender part or DOS will not recognise command !

No need to change ID's during flashing ! Program will warn you however ID's don't match ----> wouldn't expect them to since your are flashing your card with anothers bios -----> just proceed with flash !!!

Just for interest, many people have had success with BFG5950u bios, where VIVO also worked fine !

And once you find the better bios for your card, remember to also change its memory latency to "40" !

Yes I'll am planning on trying these BIOS's stock and overclocked on 53.03's and i'll mod through the BIOS's later, thanks for the advice and i'll post back later.

I am confused, surely you have your original bios ??? And if not, what bios are you currently using ???

The spec for all 5900nu and 5900u cards are 2.2ns memory chips (rated at 900MHz) !! The spec for all 5950u cards are 2.0ns chips (rated at 1000MHz) !!

The X-Bios editor will tell you very little about your card, since it is really only compatible up to GF4 cards and not FX ! However it is only the Hex editor part you need to use to make and save bios changes !

Nothing wrong with being very careful, I always recommend it to everyone !!

However don't get caught up in the hype that there's little diff between a 5900u and a 5950u ?

A 5950u is not just a go faster 5900u as some people seem to think ?? The parameters in a 5950u bios gives much better control over performance and stability at higher speeds and temps !

There are some however who have just modified their original bios with increased 5950u GPU volts, assuming this was all that mattered ? They were wrong, I tested many 5950u bios's against just modding my original bios, and I can tell you I use a 5950u bios as it gives me more stable operation when overclocked at the levels I use !!! But everybody has to make up their own minds on what they think best for them ??

Pretty excited and had to post back, on Unreal Tournament 2003 I have been running the 1024x768 benchmark and getting about 200 fps on the flyby on my gt bios at 475/950 and about 240 @ 570/1050 and on the MSI bios at stock 475/950 i consistantly get 265 fps thanks so much. Anyway off to try the leadtek and BFG BIOS wish me luck.

Although it is not for everybody's card, I personally found the MSI 5950u bios to be excellent ! And as I said, the Gigabyte to be average !! Your tests so far seem to verify this ???

I think I am going to try and stick with this MSI one the other 2 just don't compare and the MSI allows me to overclock even higher!!! plus i get about 1500 more points in 3d mark 2001 havn't tryed 03 yet but will.

I certainly found the MSI5950u bios to work well, so if you have decided to stick with it for now then don't forget to also modify the memory latencies to "40" as detailed in my Guide ! It will give you some extra performance !!

but also remember you can always change your mind at any time in future as there are a lot more 5950u bios's out there you haven't tried yet ??

EDIT:

if you are now going to run your card at much higher speeds, then watch your temps ! However don't worry too much if temps occasionally peak at 80c+ levels ? I've had my card at 90c+ levels while experimenting with extreme overclocks and hard testing !

Yes your are correct and I will be finding my overclock today, i want to get a watercooler and my goal is trying to puch 600 mhz through the core if at all possible. This BIOS surprisingly runs my card faster, overclocks higher and runs it cooler. Thanks for the ideas.
