Gigabyte K8NS 939 Ultra Modding

Hey Guy´s ,

my Gigabyte isen´t stable over 270FSB. The System boots with 2800Mhz and 280FSB in Windows. When SuperPI and Prime runs i become error. The memory runs with 177FSB. I need descriptions for a Vdimm and Vdd mod. The best would be with pic´s. And what o kind of ponti? Does give it a modding Bios for the Gigabyte?

Why does my BH-6 not run with the Gigabyte? Allways when the memory runs over 180Mhz 2-2-2-5 is my system isen´t stable. Infineon 6B run perfect on my board. Then 6A must run also on my gigabyte stable?

Sorry my English is very bad i´m from germay :p:

With A-Data PC4500 is the gigabyte instable why? :( please help

i´m interseted in the same questions...

the a-data memory doesn't runs by 233mhz with 1T. But it runs by 275mhz with 2T
so just someting can be wrong withthe board

@ 2T???????????? oh, man this sucks...

yeah thats right. I hope that a bios update brings me better overclocking scores

VDIMM mod on it, just follow GB K8N/K8NS-PRO way to do. It looks the same.

And it might help some.

Some boards are just that way...as far as 1T and 2T are concerned. Could be a bios update would fix it, but not likely a simply Vdimm is going to fix a possible compatibility issue between the board and the ram.

Just because certain ram runs great in another board, you cant assume it will run the same in another board. Put it this way, with BH5 I can run a higher fsb at 1T than with my TCCD...but change to 2T and my TCCD blows away the BH5 as far as higher fsb is concerned.

I have the mods (with pics) for the K8NSXP-939...not sure if the boards are identical.

Whats important besides board layout is that both boards have the exact layout and the exact voltage regulators.

Before doing the Vdd mod, please take a volt reading for Vdd then change the value in the bios and recheck the Vdd again to make sure I pointed out the right place to check Vdd as I dont get to fully test A64 boards because I dont own an A64 board thus no cpu to test with. The Vdimm and Vtt mods 100% and I am 95%+ that the Vdd mod is correct.

Here are the pics for the Vdimm, Vtt, and Vdd:

Vdimm = Vio (3.3v Rail)
Only solder to one of the capacitor legs I pointed out.
