Question Need info with changing PCI-e x16 frequency on a 680i-SLI

[MajorPager]

From when I posted the first thread about this system I recently got I noticed it is far too slow, even with a 960 and Windows 7 installed, although the HDD and RAM aren't doing it any justice, I need to know how to make it faster.

I bought a Intel Core 2 Extreme QX6850 to replace the weak C2D, and if the C2E doesn't work I'll try a Intel Core 2 Quad Q6700.

I was going to do some overclocking but the CPU is maxed out and the only other thing I could think of doing is increasing the PCI-e x16 frequency, but I need to know how without frying the entire system. Just what frequency should I set for the 960 without it either frying or glitching? Will it even boost any performance?

SYS: Alienware Area 51 7500 R5
Long story short, I bought this system to switch it's board out with another better board that I still have but I found out that the 680i-SLI in it actually accommodates to my wants and needs hardware wise, but it's simply too slow, and I don't want to tear it apart since it's such a perfect system.

There's zero purpose to doing this. You don't have a GPU bandwidth problem.

If you want faster performance, you'll need a platform that's not going on 20 years old. There's no magic shortcut.

Well I guess it was worth a try. Although I had an Optiplex 745 from 06' that had a C2Q and a GTX-745 in it and it did well, so I don't suppose that using that same processor would yield the same results I had before.

I finally figured out that it was the FSB speed that I have to mess around with, but since I don't really know anything about overclocking I'm hoping I don't ruin anything.

I put FSB at 1670 and Core Voltage at 1.5 and it seems fine. I am running Windows 7 so I don't get the luxuries of Windows 10's task manager so I have to use system info to check stuff.

EDIT 2: Set it to 3.5GHz at 1.5V since it really wasn't happy with 3.7GHz and it's somewhat better, I feel like I could push it more with the C2D but without the new CPU I ordered it can't get much better.

FSB overclocking was awkward when these parts were new; you're basically overclocking *everything* and that can have nasty effects. For an extremely old PC, the real-world gains are going to be so miniscule in 2024 terms that there's no benefit. Sure, one can try to mod their 1990 Honda Civic, but it's still going to be a 1990 Honda Civic and if that's the car they need to get to work, then, mostly bad things can happen.

I get what you're saying, but it never hurts to test anything; Until it does; Then you just have to fix it all and try again.

What exactly are you trying to do here? I get that you want to overclock your hardware, but why? If you want more performance, just upgrade the parts.

Get better performance for gaming and streaming.

I figured out how to somewhat do that, just to make it a little bit faster.

Well that was my first intention, but after I found out that every part on this system worked properly I wanted to keep it as stock as possible, except for the CPU and a few other things of course.


Although I'll probably use it as just a retro gaming machine as it's nowhere near powerful enough to run some of the games I have. Despite that It's still a cool unit to own.
