Albatron 5950U

[GravY]

calling on anyone to help find the bios for an Albatron 5950U.. if anyone comes across one please post it here..


thanks a Million!

[asw7576]

Yeah, ..... I need that same bios too !! Albatron FX5900UV ( Ultra)

thanks 2 million!

[larva]

I'm using the Nvidia reference 5950 bios v4.35.20.35.08 with great results on my Albatron 5900EPV.

[GravY]

Larva what have you achieved with that bios, Im running the Leadtek one right now, but would really like one from Albatron to match my card..

[asw7576]

thanks larva, I got it.

Sorry to ask...... the flash?

[GravY]

asw what are your max overclocks with the stock 5900 bios? you do have an albatron 5900 right??

if you flash it with the bios provided by Larva let me know what your new max's are..

Thanks..

[larva]

Generally, if you are running a 5900 Albatron, I am running a 5900 Albatron, and I use a particular bios, the chances that it is going to prove to be the one you should use are near 100%.

Do you have the 5900EPV or the 5900PV? My EPV came with an un-customized reference bios, so this is a good a match as any. The EPV uses 2.5ns ram where the PV has 2.2ns, but they seem to clock about the same in practice. My card did 475/995 with the stock bios, and does 520/995 with the bios above. 3DMark03 is 7106. It looks to me like additional cooling will be necessary for higher clock rates.

Most cards won't do 995 on the memory with the 5900 bios and improve up to 995 or more with the 5950 bios. Mine is a bit unique in this regard, but being that it has different ram chips than most is pretty understandable. Not all 2.2ns examples do as well as my card, so I'm pretty happy with it.

There are plenty of Nvidia bios flash utils on the net, google is your friend. I've been using the Leadtek one, but it doesn't matter who made it as all 5900s are essentially the exact same hardware.

[asw7576]

Don't know the real name..... All I know it's an Albatron FX5900 Turbo 256mb version.... maybe it's similar spec to FX5900PV but with additional memory?

I know the turbo version is using slower ram than the ultra version. The name turbo is just marketing trick.

So I just flash it, right? and see what happen....

Can I use nvflash v4.46 ( the latest flash ) from nvidia?

For your card is just wow!!! 520/995 is awesome. Is this OC with volt mod?? even with volt mod, 995 memory is lucky s.o.b !!! :eek: :eek:

[GravY]

my card is the 5900pv..

doods.... I think we are in trouble?? or maybe just me.....

My situation: I think I need original bios copy from albatron fx5950uv (ultra) 256mb version.

When I use larva bios, and I can't flash it. It gives me error. I think larva bios is for 128mb version. I get device id error and pci id error eventhough I already re-programmed them 0000.

So anyone with albatron fx5950 256mb ultra version, could you please lend me your bios??

Use nvflash v4.46 (http://www.nvplanet.com/files/nvflash/nvflash446.zip)

extract everything to C:/ drive

Reboot to DOS mode, and switch from A:/ to C:/

at C:/ prompt, type exactly lilke this:

C:/ nvflash /b 5950.rom [ hit enter] ---> to create back up bios

Done. You see the confirmation words " 5950.rom is successfully created ".

This rom will be in your drive C:/

[GravY]

try WFFlash instead ov NVflash, NVflash has issues from what I've read..

also everyone with an albatron is looking for a 5950U bios, so if you find one please post it here.

the Bios will look at what ram you have 128 or 256 and adjust accordingly on start up, all 5950U bios's are for 256mb, but it really doesnt matter..

email me and I can send you the wfflash and directions.. oogravyoo@sbcglobal.net

[larva]

Since Albatrons come with Nvidia reference bioses, and I posted the reference 5950 bios above, it is what you would get if you had a bios saved from an actual Albatron 5950u. And it will indeed work on either 128 or 256MB cards.

As well, the above leadtek flash util uses wfflash.exe. You boot from a boot disk and use the following syntax to flash:

a:\wfflash.exe nm 5950.bin

It will say the card and bios don't match if you don't use the "nm" switch. This bios will work for both of your cards, trust me.

Great pics of the 5900PV above, that's the exact same card I have except mine has the 2.5ns Hynix memory chips instead of the 2.2ns versions on the PV. These are nice reference 5900nu cards.

The 2.5ns card seems to clock as well as the 2.2ns examples, at ~1GHz. I have seen 2.2ns examples stable to as little as 950MHz, so the 995MHz of my 2.5ns card is acceptable. I saw a 5900xt (2.8ns ram) hit 972MHz with no volt mod, so the speed rating of the chips seems to have only a minimal impact on maximum operating speeds in this case.

I have not volt modded the card, but rumor is that the 5950 bios increases the core voltage of the 5900GPU, this being the factor widely deemed responsible for the increase in core speed you typically note after flashing. The memory timings are slower on the 5950, often allowing better OCs on the memory too, but at the same clock speed the 5900 bios is definately faster.

If your cooling is good on the core (and the Albatron "Wise Fan" is pretty decent, especially on the core); you can volt mod the core and use the 5900 bios for the best results. Without the volt mod the 5950 bios is faster due to the ~10% increase in core speed generally realized.

With a volt mod the core voltage can be increased manually, allowing the roughly 10% core speed increase seen with the 5950 bios to be realized with the 5900 bios. At this point the faster memory timings of the 5900 bios will most likely make it the fastest bios for these cards. A volt mod on the memory will allow ~1050-1060MHz on the ram, but will require upgraded cooling due to the monumental heat generated by the ram chips under these operating conditions.

I got what your saying about the bios.. I flashed to the one you provided and it preforms the same as the leadtek bios.. my ram just wont go that high, best I can do is 975 with out artifacts.. can't touch 1ghz.. core sits at max of 500.. can't complain this is much better than I could achieve on the stock 5900 bios..

thanks for your input..

oh, do you use coolbits to overclock?

[larva]

yep.

[asw7576]

I followed Larva's advice and downloaded the two attachments: 5950ref.bin and wwflash.exe

It works very good !!! Now I have free fx5950 ultra :D thanks larva...... you are trustworthy as always!!!

My card is albatron fx5900 turbo.

oops.... correction!! fx5950 ultra @ 550/1000 :D :D

[asw7576]

Any new bios after v4.35.20.35.08 ??

So far so good @ 550/1000.

[GravY]

I got the Albatron 5950U bios and it acutally let me go higher on my ram than the Leadtek and ref bios.. previously I could only do 975 stable on ram, could go alittle higher but would get artifacts ect.. however the albatron bios I can do 1ghz on the ram with no artifacts.. :D so best oc before bios was 460/880 (if I can remember right now.. lol ) and now is 500/1000... will run at over 500 but the card kicks in the protection and slows the core down.. :(

[asw7576]

Gravy: you have original albatron 5950 ultra bios ??? please..... please...... could you share it with me :D :D please???

can be found here.. Albatron5950U (http://www.mvktech.net/download.php?view.119)


let me know if it improves anything on your OC'ing..

That is simply a one revision-newer Nvidia reference 5950 bios. It is no more "Albatron" than the one I posted. I can't state this any more clearly than I did in my earlier posts: Albatron uses un-customized reference bioses on their FX cards.

I tried the one linked above (v09) and it does no better than the 08 version I posted. I think if you go back and do carefully controlled back-to-back testing you will find that the 09 bios vs the 08 one is not responsible for the degree of change described above.

:D :D I think what you said it's true. The bios I get from here (http://www.mvktech.net/download.php?view.119) is the same like the reference bios you gave me earlier. I'm going to test it again because I've got minor artifacts @ 1GHz memory speed (always in nature test 3dm03).

well I know it gave me 25+mhz more on my ram than two other bios's ..

I did plenty of testing between the Leadtek, refrence and this.. there is no artifacts @ 1ghz on ram as there is with the other two (to the highest I could take them).. I don't know what to tell you but, its plain as day..

[asw7576]

:p :p I think both bios are perfect for FX5950 ultra because one is nvidia reference bios and the other one is probably customized by Albatron. Albatron bios gives me peace of mind because my card is Albatron. That's is the only motivation to flash again.

BTW you can get 1 GHz memory speed artifacts free ??
