PCIe overclock benefits

Kuzma

So my internet's been out for the past 3-4 days and I've taken advantage of it to fine tune my overclocks and stuff, I increased my PCIe frequency from 100 to 110 and I had a jump in Unigine Heaven 4.0 Extreme preset from 1660~ to 1880~ with a change in average FPS from ~58 to ~75 and my Cinebench opengl score went up from 58.48 to 77.05; are performance increases like this normal or...... ?

I kinda feel silly for not doing this in the past now xD.

Most googling has come up with X58 motherboards so I have no idea but I'm probably not going to go further than this since I've heard about HDD corruption at any higher.

people moan because you could potentially lose your HDD or whatever, but I personally don't think an OC to 110 could do much harm, however this is my cap.

Yeah same, the crazy part is that my minimum FPS has gone up the most; maybe my 290 was being bottlenecked in some way idk but maxed out tomb raider was hitting lows of 45ish during big mountain scenes or high action scenes but now I'm seeing 60 fps constant (Dynamic V-Sync via RadeonPro)

it's harmless imo, I'd keep it that way if the performance increase was that much.

well i guess its time to test this with my lightning 780 :D

setting pcie at 200mhz basically makes your Graphics card run at 2 times the speed of its clocks.... so basically if you have a 1ghz gpu, your performance will be like at its 2ghz state.

How does an overclock of the pcie effect performance??

The thing is overclocking my 290 to 1100Mhz or even 1200Mhz doesn't yield the same performance increases.

i dont see the logic : /

neither do i but if it works then it works

Yeah and youll burn out your pc. If you can prove otherwise i invite you to.

I don't think it's quite that extreme but you may be onto something, I believe it's more the speed that your GPU communicates with your CPU.

i would agree. I just did a small test for the heck of it with my 780 lightning, stock on both the pci and gpu then mem oc on the gpu. then i oc'd the pci lane to 110 same as you (i have an extra sata power on my mobo for pci lanes as well) ran the gpu stock then did a memory oc again and the gains are rather huge, i think you've stumbled on to something pretty awesome xD

I'm super intrigued about this now. Anyone know exactly how safe it is do and how exactly to do it? Any help is much appreciated :D

I think as long as you keep your settings just right and dont push it past 110 youll be good unless you have a watercooled mobo. find what voltages correlate to the pci clock and set them manually if possible. i just bumped mine to 110mhz and left it though lol had to reduce my cpu frequnecy though

don't you guys even know that your Graphics card will eventually bottleneck the pcie frequency? OC'ing pcie will make any data of the card run at the stated speed, that's what i'm telling you lol.

not like you gain twice the performance....

yes but you need to account for the added power needed to run it...

he means in theory, I think he is smart enough to know that taking your PCI slots up to 200 isn't really a viable option.

 

Also, I've done this in the past but thought I'd rather not since I didn't find stability where I wanted, but that was back when I didn't want my voltage on my system to go up to more than stock voltage since it was rather new.

I also tried to overclock my PCIe, however I didn't actually find any option called PCIe Frequency in the BIOS of my Rampage IV Gene LGA 2011 (latest BIOS). All I found was something called PCIe CLK Skew, which I bumped up to +1 then +5 and lastly to +10. There was 0.2 FPS difference between the Unigine Vally runs, which could easily be called tolerance between the different runs. Has anyone tried this on an LGA 2011 board (preferably an ROG one), help me out here guys. :)
