Overclocking preventing my USB 3.0 card from being detected?

Hey gang,

I thought I would start a thread here as I identified the overclock on my machine as being the culpirit to my Akasa USB 3.0 card not being detected in my Gigabyte GA-P31-DS3L/Q6600 when OC'ed to 3.6 (400 x 9)

Original thread here

Where I am at now is that with the OC applied, I tried to set the PCI frequency to 101 in the BIOS and this failed (same for 100, its default to auto btw), resetting the BIOS.

I allowed this standard spec to boot and low and behold, the card was detected and is working as expected now, lovely.

BUT...

I want my OC back, BADLY, so I would appreciate some help in working out what part of my overclock was preventing the USB 3.0 card from being detected in any of my PCIe x1 slots?

I also noted that my USB headers are not working on my motherboar (just the case front ones, the rear panel ones are grand)

Could these have been affected by the same problem? (cant test them again right now)

Anyway....

GIGABYTE BIOS OVERCLOCKERS......ASSEMBLEEEEEEE!

Look forward to your help

Regards
Andy

Tried a DEEP CMOS clear. I've had lots of issues with the multi colored vomit products of needing this. There BIOS chips seams to get pretty confused.

Pull power plug
Press case power button to discharge PSU
Pull CMOS battery out
Jump any CMOS pins
If you smoke go smoke
If you drink pub
Make a brew, mines mile & 2 please

Give it 30 mins. Sometimes over night is needed or even all the above and a few hours in the freezer.

As you said most of the port onbord fail so it might a buggy board RMA
 
Not sure I get you boss...

The board works perfectly on the standard clock

Just my overclock kills it

I got the USB stuff sorted, I was just being a **** when it came to the pinout arrangement on my PlusView 1000 case.....

Still, I cannot apply my Overclock.

When I do, my USB 3.0 disappears

:/

Help

I cant RMA a 4 year old mobo man.....

I have noted that my GFX overclock is unstable now too.

This has to have something to do with the PCIe stuff surely.

Anyone>

Why can i not set my PCI frq to 100/101 or 98?

When i run with the oc the PCI usb card disapprears

PCI should be locked for starters.

IF GFX is also unstable it could be PSU, OS problem! Revert everything to stock and stress test it.

It all works flawlessly when stock.

Currently, the CPU is stock and the GFX is oc'd..........no problems

If i lock the pci to 100 now, no problems

When i start to ramp up the fsb, boom.......reset back to stock.

Bear in mind, if i dont touch the pci frequency at all, i can hit 3.6 using 400 x 9 on this setup no problem.

The usb does not show because the pci frequency is then out of whack

HELP

Why is the PCI-E frequency out of whack?

It's a PCI-E card so you should lock the PCI-E frequency.

If you lock it before you overclock it shouldn't change.

I was under the impression that my overclock which has been rock solid for 3 years now was causing this problem as when it is applied, i do not see the USB 3.0 card?

I have never had the PCI frequency locked and everything has been fine, even with the gFX overclock in the PCIe x8 socket

So the minute I lock my PCI frequency, my overclock fails.

Why?

Right everyone......really want to get this sorted while my pc is offline for a while (nowhere to put it atm)

So, the deal is.....I have a Gigabyte GA-P31-DS3L with a Q6600 as per my sig and it has been running faultlessly for about 3 years @ 3.6 (400 x 9)

I also have a wee GTX275 OC running very mildly overclocked.

System performance is great and gaming performance is perfect for my needs, only when running these OC's though. When both CPU and GPU are stock, the FPS drop is most certainly noticeable. My main food lately was Crysis 2 and I have been banging through the Stalker series again. All the candy turned up as far as I could to give a pleasant FPS.

However.....i bought an external USB3 drive to backup everything and keep it with me at all times.

To take advantage of this, i bought an Akasa USB3 card from OCUK.

However, when I initiallty put this in my machine (in an OC'd state), it wasnt detected.....at all, regardless of what i tried.

Now, out of curiosity....I pulled the CPU OC and low and behold...the card was detected and it was business as usual from there, albeit in a slower state of tune.

Now, regardless of what I try.....i cannot OC my rig at all without this card disappearing.

I had been advised to lock the PCI Frequency to 100 (ish) but when I do this, even the slightest OC fails.

Someone please help me......I dont understand why locking the PCI frequency to 100 or thereabouts is causing my OC to fail drastically, again....with it having worked with PCI to auto for so long.

Please help

Andy

You need to look into why this is, I take it you mean that simply overclocking via the multiplier is not successful?

Your PCI bus has probably been overclocked all this time, some cards will work others won't that's just how it is... that's why I think you need to look for the reasons for your overclock failing when you lock the bus.
 
Hey dude, sorry....should have been clearer.

Multiplier overclocking works fine, though I always preferred fsb clocking because of the bandwidth increase, you know?

So you are saying my gfx card was cool with the pci ramping up but the USB card not so much? Could this pci increase have been helping my gfx performance or hindering it?

So what on earth could be causing this?

Any fsb oc failed with pci set to auto.

Could it need more volts?

Thanks
Andy

It may have been helping GPU performance by about 0.001% but the pci-e bus has so much bandwidth I doubt it would be anything noticeable, you're most likely to see stability problems when overclocking the buses rather than any tangible performance improvement.

I remember the days when it was not possible to lock the buses at all and overclocking was a lot more difficult because overclocked buses would affect all the peripherals in strange ways.

I don't know probably just the Core 2 architecture, it might need more volts. You should probably just try locking your PCI-E and starting your overclocking all over again, see how far you can go. make sure you have latest bios.

Ok, so I seem to have been talking turd for a part.

I set the PCI freq to 100 tonight and was able to bump the FSB to 340 giving me a 3.06 speed on the Q6600.

No more though as the multiplier only goes up to 9.

I absolutely cant get past that figure however.

So without the PCI Freq set to 100 I can oc the FSB to 400

With it set to 100 I can only bump the FSB to 340


Ideas?
