Overclocking and overvolting acer aspire 6920g GPU and CPU

After the motherboard went on my sager a few months back, I had to go back to using the acer 6920g full time. I had some free time this past weekend, so I finally decided to ground the pin on my clock generator and overclock my CPU with setfsb.

< Here is a picture of the solder job before I cut the wire and soldered it on to the nearest screw hole in the motherboard.


I had to pull my video card clock down, and bump the voltage of the video card performance profile up to 1.16v with a bios edit/flash to even out the power draw across the board. I'm running a stable overclock of 3025mhz and video card clocks of 620/1515/950 (core/shader/ram).


With the SSD I have in this machine, the OC definitely added quite a bit more 'zip' to the system, and some really nice frame rate jumps in CPU intensive games like crysis 2, battlefield 3, and battlefield bad company 2. My bfbc2 frame rates jumped from about 33 to 58 even though I had to pull back the video card clocks to achieve 3ghz.

I might see if I can pick up an x9000 and may even upgrade my mobo to one out of a 6935g if I can find one for a good price. I still love playing with this rig :thumbsup

 

Good work! New MoBo (if it fits) seems to be the way to go.

 

Can anyone confirm the q9000 cpu working with the 6935g motherboard? I heard it was the only quad core that would work with 6930/6935.

 

Here's a way how you can get all of them working. Other than that, I think there were two revisions of the MoBo, or it was for the 18"? Most likely it wont work, even if it does, it's really slow for anything else but video-encoding.

 

I'm mostly wanting a quad core for gaming. And at $50, if I upgrade the motherboard, I might as well try one

I saw one post about a q9000 in a 6930 here, but no confirmation. It looks like the 6930 and 6935 have the same chipset, and hopefully the same FSB as the 6920. My current FSB chip is a ICS9LPRS365BGLF and the 6935g is the same, just without the 'BGLF' from what I have seen so far. So I'm hoping I can use the same method to overclock. Can anyone confirm?


I haven't checked yet, but I assume the bios on the 6930 is a phoenix and I know the one on the 6935 is not.


I have been overclocked wide open for a couple of days now gaming/browsing etc. And no bluescreen yet. I just wish my fan exhaust didn't blow out on my lcd :/ that much heat can't be good for it. As far as core temps though, I'm still staying in the 60-70c range when stress testing

 

As I said, I doubt that a quad would work on any 6xxx without modifications. For gaming Q9000 is worse than high clocked X9100. QX9200/9300, or don't bother going quad. Then again, what are you expecting from your machine? If you play MMORPG, then yes, a quad would be of benefit, for almost everything else, my current setup is perfect, given that I'm playing @1280x800.

 

I play Supreme Commander (RTS), with a mod to use all cores, as well as Homeworld 2 complex mod. I also would like a quad so I can dedicate 2 cores to a virtual machine. And I just want a quad What do you think it would take to get one to work? Is it not possible at all?

 

I've posted a link couple of posts above. It requires some soldering and a lot of schematics reading
