Can't overclock PCI-E !

[27MaD]

Hello guys , I've decided to increase the PCI-E frequency in the bios , but the problem is when i try to increase the frequency and restart the pc the frequency always returns to the stock value! (the same problem with CPU FSB).
so what could be the problem? i am using an overclock software that applies the OC at startup and it doesn't have PCI-E frequency OC.

Pc specs and whats the name of OC software?

You aren't supposed to be overclocking the PCI-e. From my understanding, value of PCI and PCI-e is always supposed to stay stock.

Why in gods name you want to up the PCI-E?

 

[BadFrog]

I was gonna ask the same question. Curious what OC software op is using for pcie overclocking....

you can find all the specs on system specs under my name , easy tune 5 pro

I think he means GPU, so he can finally play Pong on his microwave oven.

I call nonsense on that.

Some 3rd part overclocking software does not work well with some of the older boards, in my experience if you don't have options to overclock the PCI-E Bus in the Bios it's often locked, I have owned boards that do allow it in the Bios however even just a couple of Mhz can make things unstable, I think in the past the most I ever got a board to fully stable was 105mhz, so marginal it made little to no difference in any case.

Edit: I would not think with your graphics card even if you did manage to get it up a little you would see much difference.

I've read lots off posts on different website about overclocking PCI-E and it looks like it's a good thing.

Well , this is the overclocking software that comes with my super old motherboard (downloaded it from Gigabyte's website).
Also , there is a PCI-E frequency control in the bios but it doesn't accept any value i set.(the same problem with CPU FSB).

Don't you think that if it was a good idea AND PRACTICABLE that these autotune/Autoclock Software programs would include this in their options

PS Quoting your 1st post in your 1st post kinda stupid

From everywhere else I've seen besides what you linked nobody else has had any big performance bumps, and from everywhere else and further in that thread, by upping pcie clocks you can cause data corruption on your hard drives and potentially screw with them for very little gains. If you aren't on a purpose built extreme oc motherboard I can see why they wouldn't allow you to change it. Also worth a note that in that thread the only person who tried it was the op, which sends a red flag to me.

There were Many posts and threads "in years past"
of people having data corruption problems usual diagnosis was overclocking and many boards not having the Bios Ability
To lock the PCI Bus speed to avoid data corruption most of the problems arose if pci was raised to beyond 105%

I would guess this would be something Semi similar to FSB overclocking ,which is basically a last ditch effort when you have no other option left. Your best bet is to overclock the device you have plugged in to the PCI lane ,not the lane itself . if the only source is from that angry little munchkins website, then I don't have much faith in its benefits, never put much stock in anustechtips

Raising the FSB also raises the PCI Bus speed as with non specialized (Overclocking ) Motherboards they are on a locked Raito
Motherboard's Suitable for overclocking ( High end) have the PCI Bus locked separately from an adjustable FSB.

Overclocking the PCIe bus offers absolutely no advantage.

 

[sneekypeet]

NTune used to always clock the pci-e bus on socket 939. In those days you couldn't go much more than 104 to 105, but there was an advantage in scores with benchmarks. Is it worth doing versus corruption, not likely, but there was an advantage for those of us looking for the next place up the list in benchmarking threads here.

It is only a benefit if the PCI-E bus bandwidth is actually limiting the card, which is isn't with current graphics cards and PCI-E 3.0.

And as for that link, I can tell you the OP in that thread is 100% full of sh*t. How can I tell? He is claiming a 10% overclock on the PCI-E clock is yeilding almost a 15% performance improvement. I have never once, in my entire life, seen an overclock yield a greater % performance improvement than the % of overclock.

That mental image... ...the best part is I don't even have to change how his voice sounds in my head - already spot on.

I didn't know anybody wanted to OC the PCIE bus. Always thought that was sort of a "last port in Maine" type of deal. I remember... ...and this is going way back... having it happen as a side effect of having to turn up the FSB to sort of emulate a clock speed boost. But it was a side-effect. I wasn't trying to speed up the PCIE lol. I only wished there was a way to speed up only the CPU. I hadn't even heard of people trying to speed it up intentionally for performance gains until this thread

There's no reason to worry about clocking the PCI-E bus. Even the GTX1080 only loses about 6% when stuck on the old, slow PCI-E 1.1 x16 interface.

[Final_Fighter]

some of these replys are pretty darn harsh. hat is spot on with his reply. what the op is trying to do is not uncommon for the era of hardware he is using. there is not going to be any benefits of overclocking the pcie unluss for some reason a bottle neck exists. ive done this on some old socket 939 boards and the benefits were small and not noticeable.

 

[MrGenius]

The statements about there needing to be "a bottleneck" for any gains to be seen are false. I'm not going to go too deep into it(like trying to describe it in terms of bandwidth, which is just too confusing). It's actually a very simple concept to grasp. All you need to know is by increasing the speed of the bus you increase the speed of all the data travelling over it. "Bottleneck" or not. Don't overthink it.

Well ask them at those sites then.

Stop screwing with it.

Its a Technique used during AGP years, really isn't noticible.

As you said , i want to pair a GTX 750 TI with my PCI-E 1.1 *16 and it's a PCI-E 3.0 Card , so i think it's limiting the card .

It's not , I ran benchmarks on my 1060 on PCIe 1.1 and the differences where within the margin of error. And to put things into perspective that's a card about 4-5 times faster.
