Smile DMI Lanparty UT nF4 Ultra-D BIOS help

Hey all I have been playing with OCing with the Ultra-D MOBO and am interested to get people's takes on what version BIOS is the best.

In particular I am interested in OCing the system in my sig and want to squeeze the most possible out of it.

I am currently running the 6-23 bios I believe. If anyone thinks that another would get me a better OC then by all means give a yell!!

Thanks, I think it will be interesting to hear peoples thoughts on the various BIOSs for this board.

I'm using 704-2bta although I'm thinking of flashing again as I'm having some issues with depends entirely on your hardware though and there are way too many BIOSes out there to really specifically pick one for you

I was using a modified 310P BIOS with support for RevE cores when I had the Venice and it helped get my memory up to 280

Intel C2D E6320 / AMD Athlon X2 3800+
Gigabyte 965P DS3 / DFI nF4 Ultra-D
2GB OCZ Gold PC2-6400 / 2GB OCZ Gold PC4000
eVGA 8800GTS 320MB / eVGA 6800GS 256MB
150GB Raptor / 74GB Raptor
2x500GB / 320GB
OCZ GameXStreme 850w / OCZ StealthXStream 600w

Newer BIOS' for these boards will come in 3 versions. You will, for example, notice a 623-1, a 623-3 and a 623-3. (BTW, boards will always ship with the latest official general/unoptimised BIOS i.e. if you bought an nF4 Ultra-D now it'd arrive with the 623-1 BIOS).

-1 = General BIOS for all RAM. Not optimised for any particular type.
-2 = Optimised for BH/UTT BH/UTT CH.
-3 = Optimised for TCCD/Micron.

BTW, the 623 in the example used above refers to the BIOS being released on the 23rd day of the 6th month (of 2005).

The difference between the three BIOS versions is the ROMSIP table used. A ROMSIP table is the memory controllers internal timings and along with the correct alphas can make a big difference to how your RAM plays. Some configs prefer one ROMSIP type, some another, hence the comments below.

As always, the above is not an exact science, it is merely a rule of thumb. I have seen people running for example TCC5 on a "-2" BIOS with great success yet I have seen people trying to run Micron -5B D in a "-2" or "-3" BIOS and the result was a no POST and a while spent sorting it out. The general BIOS will be fine for most types of RAM, it is really only if you are pushing for stability at high clocks that a BIOS designed for your specific mem type may become useful. With regards to slots, Orange is recommended as they generally work better than yellow, but as always, you should really test for yourself to find out which arrangements work best for you. However, if you're lazy, just follow the recommendations.

If for whatever reason you flash to a BIOS that doesn't like your RAM, and you can't POST or the BIOS hangs, you need to power down, clear the CMOS, put a stick of RAM in the top yellow slot and then power up again. The system should now at least POST, meaning you can then flash to a more appropriate BIOS either from within DOS or via WinFlash in Windows.
Since I have TCCD's I am using 623-3. I don't know what IC's your RAM has, but this could be used as a guideline for you.

Anyone know how to find out exactly what my ram would be? All I know about it is basically what the newegg page I bought it from said lol.

Thanx for the input synergy, if I find out what kind of ram I have I may try flashin to a bios from that snippet you posted.

they are probably TCCC's since they are 2-3-2-5 and not the complete high end which would be 2-2-2-5.

Those BIOS descriptions are primarily for the complete high end RAM which you don't have. Although yours is higher than regular valueRAM it's not the 'top of the line OC'ing RAM"
