Anyone here has MSI K7N2 Delta ILSR? Any modded BIOSes for that board or any review?

I had this board some time ago. It was nice but my board it wasn't a great overclocker. Afaik the BIOS was limited to 233MHz FSB. It did that clock 3D stable though.
There should be a mod BIOS for it.

WOW!!!!

@supercordo
Something went wrong with the 1M highscore list. Seems you placed Sandmans score as 1st, but there's still digitalbaths name next to it.

Try this:

I have two MSI K7N2 Delta-L (the red PCB one with the old SB, not Delta2). The better one topped out at around 240-245Mhz FSB and the other maybe 235-240. My boards got a very old production week (older than week10 of 2003), so that was expected. In general the better chipset weeks are mid-2003 to mid-2004.

I finally made a pair of 256MB BH-5 sticks, installed them in my water cooled NF7-S 2.0 (vcore at 2.0v) running vram at 3.2v via a POT. To my horror, I still cannot go past 235 FSB, no matter what multiplier I run. Windows fails to load. Could I just have bad luck with the chipset on this board?

Which bios, is it modded? Have you tried other types of Ram? Are you sure the BH-5 are "good"? Tried another cpu (which one are you using)?

Yup, I sure did. I'll fix it tomorrow. Thanks.

There all fixed!!!!

measure please the VTT voltage for the dimms. It should follow the rule 1/2 of the Vdimm voltage. Afaik some of the NF7 board (revisons) won't follow the 1/2 rule if you do a voltmod. In your case it should be somewhere at 1.6v.
The Kyocera caps may not necessary be a problem. I would check other parts first.
My NF7 boards are not great overclockers, but they manage to clock higher then that. I would guess somewhere >245MHz should be possible.

Did you check the dram subtimings? Maybe worth to check slower subtimings?

I’ll check the VTT voltage and subtimings this weekend. Glad to know the caps shouldn’t be a problem at this stage.

I’m using D26 Manta Rays XT with CPC on. Should I be using something else? I’ve tried other types of ram but still cannot get past 235. I’m using a XP-M 2800 AXMJ2800FHQ4C (with “I” stepping). I have an unlocked XP 3200 (03 week 24) and a XP-M 2400 I could try?

D26 Mantarays XT is a good starting point. Usually a good chipset manages to pass 235MHz with this bios. You can try either a Merlin bios (Taipan 0.3 ED) or - my preferred option - a bios by digitalbath (ED or ED55). Make sure to keep the Cpu Interface option enabled (aggressive / on), else the board will fall back to slow default romsips which will limit your OC. This does also apply to D26 Mantarays XT, iirc it didn't clock well with interface off.

Also: have you tried using a bit higher chipset voltage? To pass >235Mhz 1.7V might be needed. Please don't just raise the Vdd voltage to the max, as some boards and chipsets seem to counterscale past some point. So try 1.7V first before pumping lots of volts through the chipset.

NF7(-S) v2.0 Merlin bios files: https://biosbude.de/%21%20BIOS%20VAULT/Abit/N … %20v2.0/merlin/
NF7(-S) v2.0 digitalbath bios files: https://biosbude.de/%21%20BIOS%20VAULT/Abit/N … .0/digitalbath/

In general i'd try higher FSB at low vcore and low multiplier first. Usually a good approach ist to try multi 8 or 9 and push for 250MHz. Any cpu without superlock should work for this, as 250x9 is just 2250Mhz. So 1.7V Vcore should be enough to get that stable. Mind thatt multi 10x and 10.5x will limit your fsb OC compared to 8 and 9. Also stay away from half multis (8.5x 9.5x) for your initial testing.

You could try another CPU, but I don't think it is a problem. Have you tried a single channel or a 256 MB stick?

Be careful with that! Tictac only used the modded romsips in his Mantarays XT BIOS when "CPU Interface" is set to Disabled. If you enable it, the BIOS reverts to the default Nvidia romsips. This is unique, as most other custom BIOSes actually require you to keep the "CPU Interface" option Enabled.

-----

Mantarays XT runs well because it shares the same modded romsips as the 619XT BIOSes. As a side note, every known modded romsip actually traces its roots back to the DFI NF2 Ultra B Beta BIOS releases.

Merlin ED romsip from DFI 200MHz beta von 12-31-2003
Infrared's ED55 romsip from DFI beta 200MHz 05-05-2004
Mantarays XT / 619XT from DFI beta 200MHz 01-31-2004
Hellfire, Rev.2 from DFI beta 200MHz 12-10-2003
Hellfire, Rev. 3 from DFI beta 200MHz 12-31-2003

My custom BIOS versions offer the option to load one of the Beta romsips directly via a built-in preset.

Less talking more benchmarks!!!!!!!!!!!!!!!! Your mom said so.
