Thank you for answering so fast
No. Only the superior powerplay features are gone then.
Ok, I did as the FAQ said, and opened a saved BIOS with them Disabled (Enable/Already Enabled was checked). Nothing changed tho

. I guess they are already hard coded?
Increasing the overdrive headroom does not mean your card runs these clocks all the time. Nothing will change at all if you don't have overdrive enabled.
Well what I was reffering to is that the "standard clocks". If the increase overdrive limit tab, does only that, increasing the overdrive in CCC only and nothing more, the expresion "Standard clocks" made me think the standard clocks will change too. For example under actual settings, it's Standard Clocks 750/900 (which are the rated clocks), with the upper limit 790/1100 (same numbers I have in CCC). Now with the Hash check method, and the included 4870 settings, it says "standard clocks" 800/1100 and upper limit 990/1200. Compared between, at least myself, I understand that the limit in CCC will now be 990/1200 and the GPU clocks will not be 800/1100.
First of all, you should read and understand the
RBE tutorial carefully. It seems you didn't (entirely) understand several basics of the powerplay mechanism yet. Please be sure to entirely understand what you are doing before tinkering with your BIOS.
This would be related to the above statement. I thought that a new "standard clocks" means it will change the standard 750/900 clocks to a 800/1100 value.
You need to understand your BIOS. The RBE tutorial will help you doing so. Then, you can answer this question yourself.
Ok, I think I just know. Because my windows mode (which I guess is the notebook blabla powerplay state structure) is 200/500 on the line for all low, medium and high modes. For it to activate to 750/900, it has to detect a 3D acceleration state, which I guess it's done when entering full screen. If you stay in window mode, it uses the windows state, and since my windows state is 200/500 for all 3 modes, it only uses 200/500, even tho it's an actual game.
Now my question is the following: in the FAQ you gave a nice rule when windows might find it self in low, medium or high. But is there an actual written "rule" in the BIOS when it switches between the low, medium, high that you can check? Or it's just a "it should" because that's how it's hard-wired.
What I'm trying to say, is there a way for an average joe like me to know when the modes change and what triggers them?
The reported values are irrelevant. Think about it: The reported values are valid only for the video board the BIOS has been extracted from.
Ok, so basically, it's safe to assume that the max voltage wired in the card is the value found in the original BIOS? Therefore when you flash to a different 4870 BIOS, any voltage which is over the maximum voltage found in the original BIOS might not work? And if it doesn't and you select a 1.276v when your card maximum is 1.265v, by selecting 1.276 will it crash/damage the card, or the card will simply run with the voltage nearest to the one you selected, that being 1.265v? (or what i'm trying to say is something similar you write in the FAQ "various things may happen") Or just use the voltages that were available with the original BIOS and ignore all other values in the different 4870 BIOS to be safest?
Regarding changing BIOS with another 4870 BIOS, how "viable" is it. I'm asking this because of the huge BIOS database you can select on this website. Is there a reason why to use this method vs changing the settings yourself (to the same settings you would find the the other BIOS you want to switch) in your own BIOS?
A new question. If the clocks for the core and memory decrease, you save power. By decreasing the voltages also, I guess you save even more.
Now if my BIOS has 200/500 @ 1.10v, 500/500 @ 1.20v and 750/900 @ 1.26v (1.26v being the max), and I want to change the value to 200/900 (first value), is it safer to just set it @ 1.26v rather than 1.20v?
Another question: What exactly is that Hysteresis % value. I mean I have read the FAQ, wikipedia the word (not native english speaker), read the guru3d forum explanation by unwinder, but I just can't exactly get it. If you could just give me an example what is the difference having hysteresis % - 4 and hysteresis % - 24, everything else identical.
