Help! Intel 945 Express Chipset, OC Possible?

post #1 of 9
Thread Starter 
This is my first time posting.. I've been scouring overlock.net and google, no answers yet so here's my post:

I purchased an HP Mini (See Sig) for presentations. As of right now I am obssessed with trying to squeeze as much performance out of it as I can. Please don't question my motives, I know this machine wasn't built for graphics, it's not why I bought it either, but I want to OC for the sake of OC'ing!

I've upgraded the memory from 1GB Elpida chips to 2GB/low latency G.Skill memory. This had a great performance gain of course, and was statistically the best chip with the best ratings, that I could find.

I will be upgrading the 1.8" HD to a SDD shortly.

As for now I'd REALLY like to know 2 things:

1: Is there a way to overlock Intel's integrated chips and how?
2: Is there a way to force shared memory? BIOS is fully updated and lacks the functionally to increase shared memory allocation. Intel's drivers/software do not allow this either. The closest thing I can do is increase the chips memory footprint....not the same thing.

Riva & ATI tool do not work either ;(

Any help would be much appreciated! Thanks!

I seriously doubt a software based overclock will work on it, but you could try ClockGen. Laptops are not the best dissipaters of heat so if you can overclock it you need to be very careful. I have not seen anything about overclocking an Atom, yet...

Thanks losttsol, that's a way cool tool.

The laptop stays relatively cool all day, with the RAM being the only exception as it gets warm.

Now to find a tool that will supply the chip with more shared memory!

Any ideas?

Do you mean force shared video memory? I don't know how to do that, but it sounds possible with the right driver perhaps. You could increase your virtual memory, but I doubt that would help it do what you want.

shared memory / shared video memory, same thing. shared memory doesn't really have another partner to be shared with, other than a possible ramdisk, but this is a post under graphics cards, so we'll rule that out!

Increasing virtual memory wouldn't help ;( Right now VM is disabled. 2GB is enough to run my apps and games without the need to spill over to VM. And VM on a 4200 RPM HD is horrible. The biggest benefactor in getting the 2GB SO DIMM was the ability to disable the VM entirely as I'd raised the PM ceiling 2 fold.

Performance would be a lot better if I could get the Intel 945 to use more of the new physical memory. currently the system is 1920MB/128MB System/Video memory. 1792/256 is what i'd like to achieve.

From best I can tell the 945 chipset can only address a maximum of 224MB video memory. With a locked BIOS you may be out of luck. If you could flash to an unlocked BIOS then perhaps.

im sure overclocking an integrated graphics chip on a laptop is asking for trouble

Exactly, that's why they handicap the BIOS so you won't do it.
