NX860XL 7900 gs overclocking?

Alright... I'm a bit inexperienced with overclocking notebooks.

I have an NX860XL with the 7900 gs. What would be the best method to go about overclocking this? What programs should I use?

I was confused as to if I should just follow the instructions on the "Official 7900 gs overclock" thread. I know it sounds stupid and it would seem I could, but from what I read on that thread it seems its only for Dell notebooks with the 7900 gs?

So if I should just follow those instructions, let me know, if not... what would be the best program to use for OCing my go 7900 gs GPU?

 

Yeah, you shouldn't have to go through the hell that we e1705 and m1710 owners have to go through. Dell locks the BIOS of its hardware, so the only way to reclock it is the manually reflash the BIOS with the clock setting we want.

You should be able to download xtreme g drivers from tweaksrus.com that will have an overclocking function built in. If not, you can use powerstrip.

 

Hmmm... I'm trying to overclock with Rivatuner, yet it seems whenever I click 'test' and then 'apply' it does not change the settings at all. I have the hardware frequency graphs displaying, and the core frequency does not change at all even when I 'apply' the new core frequency... does this mean they've locked the BIOS, or am I missing something.

 

They could mean they have locked the BIOS. That's the same thing that happens on my Dell. But then again I don't know about Gateway.

 

Nice looking notebook.

You might try posting over on http://www.notebookforums.com/. They have a pretty strong Gateway forum.

 

Thanks for the help. I'll check the Notebook Forums. Although, after looking at some info off of Rivatuner, I'm having some second thoughts about overclocking this thing. The GPU core temp at idle is about 67 and after about a good hour of Oblivion gaming it got up to 90. This thing runs hot... although both of those were with it sitting on a carpet-like table cover. I'm thinking this could be fixed with a laptop cooler.

 

If your temperatures are that high, it would be a good idea to leave the clocks as they are before overclocking. Looks like doing that adds heat pretty quickly to the Go7900GS.

 

Yep, 90C is a bit scary. I would move it off the table cover. When you get a chance please post your clocks. You can use NiBiTor or other utility.

 

My clock, according to Rivatuner, is 375C 500M(?), but that memory clock is ridiculously low... "499.500MHz (999.000MHz effective)" Is the direct report from Riva. When referring to memory clocks, is it the effective that most refer to? According to hardware mhz graphs from Riva its running 499.5.

 

Those temps given were before overclocking... a bit scary.

 

375/1000 is stock... the memory is DDR...500=1000. You hit 90C before or after OC?
You need to get with another 860 qwner to get some default temperture readings, somethings not right if your hitting 90C at stock.

FYI im' running OC 500/1100 on my dell. I use I8kfan during gameplay that gives me peaks of 79-81C.

 

Well, I've elevated the laptop about an inch off the table and removed that table cover, and I'm getting 58 idle and peaking at 77 during gaming... should I go ahead with the OC? I'm thinking get it so it peaks at 81-82 at very max.

 

Well... I went ahead with the overclock, but got the following error when I tried to flash the BIOS.

ERROR: PCI Subsystem ID mismatch

Any ideas?
