BIOS modding for GPU OC fun and profit!!

Once again, what GPU are you running? The 5730 should have next to no throttling problems, and should upgrade to A11/A12.

The 4670 does have throttling problems, and should stick with A09.

I SHOULD upgrade? what are the benefits? Just wondering because mine seems fine. I have the 5730 as well. After I am done my paper i will look up A11/A12 fixes. I wish you could add pipelines!

Well maybe should isn't the right word, but there is no reason not to upgrade if you have the 5730, and there were some small improvements made.

Lol, no, the days of unlocking disabled pipelines are long gone. It's too bad, but I think ATI learned their lesson last time they tried that.

Well I flashed ur mod. That was super simple! I was thinking it had more clicking. Anyway I will see what this baby can do now. In furmark I went from
Min-8 Max-12 Temp-76 to
Min-10 Max 13 Temp-78
Will play Black Ops soon to test it out. Thank you very much! Is the fan supposed to be constantly running? I have not heard it stop yet but Ive only just flashed it. Before it was a very silent machine.

EDIT: Results from OC
I am able to run Black Ops on highest quality with shadows on 1080p without AA and I get 30fps! Sometimes it will hit 60. Taking off shadows improves fps but why would you not have shadows? Playable just wouldn't have it on this setting online with the current bug. On 720p with 4xAA, shadows, highest settings, it is perfect.
Fallout: New Vegas ran nicely as well! Very playable, 1080p. On Ultra i get 30s fps, High i get 40s.
L4D2 i get 288 FPS in the menu! yay! I actually dont know what it was before but the 5730 run this perfectly on highest setting 1080p stock but it is definitely a little smoother which is nice.
Downside is the card hit 81C which is 2C up for before.

That's a good thing and perfectly normal that your temps went up. Correct me if I'm wrong, but it means your CPU is working harder now to keep up with the GPU. The GPU is easily still the bottleneck for games, but it allows the CPU to do more now. And since they share a heatsink, some of that temperature will spill from the CPU to the GPU.

seeker_moc, can you do a mod that will upcap the RAM speed? I am putting new rams into my 1645 that have the speed of 1600MHz and wondering if you can do a mod that to lift the capped speed of 1333MHz so I can fully utilize that speed of 1600MHz?

Unless I'm not understanding what he's asking, you can't do this without increasing the base clock of the entire system. The memory controller is what is limiting the speed here. Much like my XPS 1647 Core i5 mobile is limited to 1033 because of the memory controller, I think the Core i7 mobile memory controllers are limited to 1333.

That is correct. The memory controller for quad cores is on the CPU die, and is limited to 1333 (for the dual cores it's on the integrated GPU die, and limited to 1066). I'd recommend against trying to overclock the entire system, with the heat level / power consumption that the CPU is already hitting at stock speeds.

I understood this, that is why I am asking if you can do something to the CPU controller to change the limit on the RAM or not

It is possible, but I don't know how. There's a lot of threads over in the gaming board about people looking to overclock i5/i7 laptop CPUs, but from what I've read, they've had no success with software tools. You'd have to alter the ACPI tables in the BIOS to do it, but I haven't dug that far into it. Personally, I'm more interested in trying to undervolt the CPU to lower temps, but I just don't have the time to do all the research involved.

If you are interested in doing this, you'd be better off asking over in this forum: Computing Life They are a lot more knowledgeable BIOS mod people over there than around here.
