I've only seen small increases with higher pci and pcie speeds.
Generally these days the mem bandwith doesn't change with an increase of the pci/pcie bus like it used to.
Mainly what I want it for is pcsx2.
That thing is pretty hungry for vga texture upload bandwith.
Increasing to 150mhz might net say 4fps more but I haven't checked.
Lowering from 9t in mem to my 8-9-7t timings got me another 5fps in pcsx2 though.
5fps in pcsx2, is not that small .
Especially when you're fighting to get it past 60fps with a cpu at 4ghz .
(in certain cases, some ps2 games use need alot more power)
What I'de like to do is keep the pcie bus 1:1 with the fsb or 2:1 (500 pcie : 250mhz fsb).
In the past I haven't had much probs getting higher then normal bus speeds.
It all depends on the board.
Some board can clock good, most can't.
This asus ch4 seems like it can though.
150mhz is doable I know it is.
On my dfi ut 790fx-m2r 250mhz pcie, the limit in the bios, was pretty easy to do with a few bumps of the voltages.
Not all cards can doit though.
Most nvidia cards can.
The vga card's mem gets power hungry at higher bus speeds though, always seems to on every single card I've tried.
Sometimes I don't need to do anything, but other timees I need to up the bus voltage.
If I remember right, the south bridge needed a tiny bit more voltage on my older board too, I think it used the pcie bus to comm between the nb and sb.
I should probably double check that on this board...
I just thaught about something.
I redid the heatsinks on this board twice so far.
The 1st time my nb temps got over 60c when before hand it reached around 40c.
I had moved the screws to diff spots on the board, pwm, sb and nb screws.
When I put it back together it worked better.
Back to around the 40's for nb temp.
If the nb was having a prob that would explain my vga card probs, I think the pcie lanes for the top pcie slot are hooked to the nb and not the sb.
At least it was that way on my dfi.
If grinding down all of the screws a few mm helps I might just try that.
Might be my prob right there...
Yeah my cpu is a nice one, I'm surprised it does 4ghz on stock cooling myself.
I do need to replace my modded enermax 350w psu though lmao.
I really think I'm cutting it close with that thing.
I'll brb
Edit:
Cpu voltage: -0.0625v
Cpu-nb voltage: 1.125v
I have c&q enabled, with turbo enabled.
14x cpu ratio, turbo @ 16x.
It works well enough, the voltages are a bit higher then what I really need though.
I'll post my bench in everest.
Some of my secondary timings are higher then what they probably need to be though, I up'ed them thinking I was fixing my vga issue, lol..
