GUIDE: How to use SETFSB with non-barebones bios!!! Look it very easy. (example shown for GT627 but should work with all similar)

So I had a problem, I needed the northbridge options in the BIOS that were not given in the barebones BIOS.

But I needed the barebones BIOS to use setfsb, or so I thought.

Anyway, right now I'm on the 1.0T bios version for the GT627 (non-barebones BIOS) and I have setfsb working.

Here is how I did it:

1. Flash the barebones BIOS and EC firmware (PM me for link if needed), open setfsb, click on the diagnosis tab, click getfsb, move the top slider a bit (1-5mhz), click setfsb then click capture.

That will give you a screenshot with the registers that are "good".

2. Flash the non-barebones BIOS you want (if you have a GT627 I suggest 1.0T because it gives lots of overclocking options and NB options).

3. Open setfsb, click getfsb, click on the diagnosis tab. Now look at the screenshot you made before, copy the registers from the screenshot into setfsb manually, hitting update and apply.

now you will see your 1-5mhz overclock, but the best part is that you can also now use the slider. So using the slider, OC as much as you want.


Only thing that is needed now is to get nando4s GRUB OC and that will let you set your registers automatically at startup.

I will update this guide when I get that done.

Until then, try pressing turbo* after overclocking with setfsb and see what happens

Screenies:

Here is what it used to be like (using non-barebones BIOS), you press getfsb:



When you move the to slider and press setfsb (as you can see, you get wrong values for the FSB):



Here is what it is like after this trick:


*ok, I'll tell you the secret about turbo, after this mod, it's gone...

And finally I have attached the OC that you cant get without setfsb (250mhz FSB, I can go higher since I have control over the ram now, 2.7ghz should be possible for my T7300 without a volt mod, but the temps are a bit high):

 

Nicely done moral, i'm sure alot of users will be happy to see this .

 

Thankyou

I believe users with the latest BIOS may be able to get a 20% OC (not 15) by changing a few bits in setfsb, I will do some tests and let you know soon.

Also quad core users can get >4% OC too, I think, I need someone to do the test for me since I dont have a quad...

By the way, my 3dmark06 score went from 6763 to 7183 just by taking the CPU from 2.3 to 2.5ghz.

 

Yeah, 06 is quite bound to CPU, pretty big jump though,

And i agree, surely quad users can get past that, restriction? haha, we need some test puppets, i could do it but i don't have the turbo button so it'd be stupid haha.

 

Found a fast way to load the "good" registers without having to type them all in, just download RW-everything, click on clock generator, change the registers to the "good" values, then save that.

Next time you want to overclock with setfsb, just open RW-everything and load the registers you've saved.

I have attached my saved registers for you:

 

CONFIRMED WORKING ON MY Q9100 in my GX720! FINALLY! I LOVE YOU!

BIOS version 1.11 latest, replaced with proper registers, and it works! OMG!

Quad cores now running at 2.7 GHz vs 2.26 original!

 

Hey that's great

I also found a way to chance the "turbo" %.

 

eh? I will try this for the quad core....

 

Mine still reverts itself after a split second. But it did run at 2.3Ghz instead of 2.0 for a second or so.

 

Maybe it's got something to do with SCM?

 

Seems so. Did the trick and 24% immediately froze my computer. Got the numbers for 12%?

Edit: Nevermind. I still can't get the stuff to stick.

 

Just an update, clockgen can read my registers if I select ICS9LPRS509.

If you then change the bytes you want to change and go into options and select "apply current settings at startup" it should save you time. (I didn't test this yet).

EDIT: Tested this, doesn't save the changes I made to the registers.
