PCI-E Bus Clock

[Jesta]

I am using the blood iron p35series mobo, Is there a way i can over or under clock the pci-e bus on this motherboard?


edit: nm, easy find when you read the instruction manual heh :)

Be careful there though. Raising the PCIe bus off of the default 100 doesn't do much for performance. There's already enough bandwidth and speed for video cards. I could see raising it 10Mhz on large FSB/MemFreq clocks to time things up a bit closer...but not much more than that.

Report back the good and possible bad once you're done tinkering please!

Risky work there, corrupt data is a possible side-effect. Make sure you back up all for good stuff first. Anyway, best of luck to you!

EDIT: sorry, I was wrong, ive just read on a few places that video card damage isnt likely with this.

i was actually thinking of lowering it, since i have a 9600gt installed.

i havnt done anything yet though.

Lowering it can have the same effect. 100Mhz is the send receive rate. Lowering the number lowers effective bandwidth and can also get data off timed. The 9600GT isn't a low end card that doesn't need the 100Mhz PCIe bus and what it has to offer, it's just midrange based on the 9-series of cards. It's relative, and I'd feel you'd like to keep the 100Mhz bus running as is. Having troubles with it?

yes, it is a complete PoS. And i cant RMA it because it doesnt have a serial number on it.

EVGA basically released a bad batch of cards, they know about it and are offering free RMA's. But I cant get one.

Basically this card has destroyed a brand new build of mine. I have had blue screens and reboots non stop since building it, and Im thinking the constant errors, and it being shut on and off has started to make other things go out. Today it took me 8 tries to get my computer to boot up.

It beeps nonstop and never gives me a screen, or it gets past bios and says drive error and halts, or it will get to the HD and say systemboot error please insert system disk.

Im so frustrated and depressed right now. I made a new computer of supposedly quality parts and it has never worked. I nearly took a hammer to it today. I really wish I just would have bought a PoS dell. As much as i hate them i basically just threw $800 away on this computer.

I doubt a faulty video card would give you those symptoms. I'd lean more on a faulty motherboard/RAM/cpu at this point.
To not let the computer boot or not display anything is one thing, to say "drive error" at BIOS level and the likes is another.

I've been down on eVGA for a while. They have great support because you actually need to use it...a lot. eVGA clocked cards (higher than reference) are becoming known issues really. The fix is usually down clocking the cards you paid more for.

However, the errors you get are useful to try to pinpoint what is actually to blame. System errors give those beeps, and they're in patterns that are telling you what is faulting. Non-stop constant and repeating beeps sound more than just the card, but something more critical...like memory and CPU, which can also be the motherboard and/or settings as Polo states.

And to be a stickler, I really like the rule of having systems in a signature here at HL. Doesn't have to be glam, but just knowing what you have for us to work with is a huge plus!

What kind of Power Supply are you running. I say go in the bios and load defaults for starters.

I have already troubleshot everything. It was the video card, but like i said, 2 months of non-stop crash's seem to have started causing more faults in my computer.


I have down-clocked my video card from 650mhz to 500mhz, and now it runs stable. But nothing else does.

Where as a month ago, everything was stable except the video card.

I have 2 threads already in the trouble shooting forum, with all my computer specs. But, we have already went through everything... twice.
