Hey, I just started to mess with the boost states - GPC, XBAR, L2C & SYS. I have some questions for those of you who have tried doing this yourselves.
My questions are:
- Can these states affect the highest stable core clock speed?
- If so, how? If you set lower boost states, can you raise the core clock higher? Or is it weird and awesome and the higher the boost states are set, the higher the possible core clockspeed?
- Stemming from the questions above - does a higher offset on boost states equate to more potential for raising the core clock?
e.g. someone with a stable +200 on boost states is closer to an extra +13MHz on the core than someone with only +50 on boost states.
I am offsetting the original values by the same amount as some people have suggested, giving me an offset of +183.5 from the default BIOS. I tried higher values and setting them all to be the same, and this gave the best results in Firestrike Extreme -
I don't know how truly stable this is, but I see no issue so far. I'm going to stick with this BIOS for a while and see how stable it really is. The values seem crazy high to me, but if it works, it works! The high values are also making me think that there is more potential for the core clock on this card than what I've managed to get it to, which is why I asked the third question above ^.
Before this, I found my max stable core clock to be 1455MHz with all boost states at default except for GPC, which I changed to match the core clock (actually meant I downclocked the GPC).
My final question is should I try to raise the core clockspeed now that I have raised the boost states, or after lowering the boost states to below what they are in the default BIOS?
Or would I just be wasting time and electricity?
I've been using this thread to 'bake in' my overclocks for maxwell GPUs for a few years now, this is an excellent resource! If anyone can share their advice I would be very grateful.
