Something in my setup ain't right...

I'm quite an overclocking newbie, and have been trying to overclock my Opteron 144 CABNE on a K8N Neo2 Platinum.

Say for example I want to overclock to around 300Hz with a 9x multiplier. I have to reduce my memory to 133, put the HT Frequency to 3x and disable cool and quiet.

But even at 245Hz-250Hz, the system's very unstable, and sometimes fails to boot. I'm sure it's just because I'm missing something, but what is it???
 
Hmm

Have a read through Praetor's OC 101. Have you raised the Vcore? If not, then that could be your problem. As to the above post, I would expect more maturity.

ok, he expects to get 2.7 out of his system when hes probably not supporting right volatges, etc, how is this an 'immature post'

its the truth

this is an immature post.
keep it up and you find out what happens to people that lack the maturity and friendliness required to stay a member of a place like this.

calling someone an idiot when they clearly state that they are new to overclocking is more idiotic that not being able to figure out why they are having problems overclocking.

jan's suggestion of reading the OC101 should give you a few good pointers for your system. remember to keep the speed and voltage increases small and you should be fine, keep an eye on the temp under load conditions.
also, make sure that the PCI/AGP lock is set in your bios as this is one of the most overlooked aspects of overclocking when you're trying overclocking for the first time.
 
I wasn't trying to get 2.7 on stock voltages, for your information, like I said I wasn't able to clock over 245Hz, 300hz that was my final target, and since plenty of people have been able to get stable overclocking of 2.6-2.7 on stock volts with this processor, I was not expecting the problem to be a volt one.

What I had forgot about, which Hairy Lee had kindly pointed out, was the AGP lock. I knew I was overlooking something, and that was it.

To Ctcoyote16:

If I am able to swallow my pride over a basic overclocking error, I'm sure you should be able to be mature enough to not flame someone when it is clear that you have nothing constructive to add to this thread.

Everyone else: thanks.



Edit: I thought the AGP lock was automatic on this board? It's certainly set at 66, so wouldn't that do it?

OK, I've discovered what the problem was. Apparently using the first two SATA ports actually overrides any PCI/AGP lock that I put on. So even though the lock was saying active in the bios, it didn't really matter.

Looks like i'll have to invest in another HD now...
 
buy a sata controller card, it runs through the pci slot so there's no problem with the agp lock and its much cheaper than buying a new drive

1. Dont call people idiots for no reason. Someone comes for help and you call them stupid, which doesnt say much about you.
2. 2.7 Ghz isnt high for that processor if you want to get technical

Magicman where did you manage to find that processor? I thought CABNEs were'nt being made anymore... lucky :P

Hehe, yeah I was. I contacted the vendor (scan.co.uk) before I bought it, and they said all they had in stock were CAB2E's. Imagine my delight when I opened it! It's a 0545, so not as good as the earlier ones, but still.

I'm still not getting very far with this overclock. I've unplugged SATA's 1&2, but still it's not getting past 245hz. At 250hz the monitor never turned on and after resetting the CMOS jumper found the overclock had corrupted my windows installation, but I was able to recover it with a repair install...

Surely this shouldn't be happening??? Im at a loss as to what the cause is. OK I'm an overclocking newbie, but I've read plenty of guides, including the one on this forum courtesy of Praetor, and am running out of ideas.

To summarise: I've underclocked the memory to 133, put the HT Frequency to 3x, raised the HTT to ~250, locked the AGP at 66, unplugged SATA's 1&2 and disabled C&C.

Any ideas? This is turning into a bit of a mess.
 
Turn your multi down to around 4-5 and LDT to 2-3, then start rasing the FSB. That way you can find out if its motherboard HTT limitation or your just htting a CPU wall.
 
Right well did as you suggested, lowering everything but the FSB, and it failed to POST at 245hz. When I reset the jumper and went back into windows, it took ages to load stating it had found new hardware, such as floppy and ethernet. They had already been successfully installed before the overclock.

From that do you think my motherboard's faulty? Or could it still be an AGP lock issue? The windows installation is on an IDE drive, and my hard drive on SATA port 3 is always stable. But as stated above it's already corrupted an IDE installation.

Thanks for all the help so far guys.
 
Ok, so that cuts the CPU out of the problem.

Its either something not locking (AGP, PCI, SATA), or just a motherboard that doesnt like high FSBs. You said it still wont post at 245 even if the RAM is at 133 Mhz right?

How did you lock the AGP? I know some boards you have to set it to 67 Mhz to lock. Make sure you are locking the PCI slots also. Just out of curiosity try turning down the speed of these slots.

Whats your vcore?

Also try raising the chipset voltage. 250 Mhz is usualy where most boards need more juice.

I'v been reading around now and it seems that that board maxes its HTT at around 300 Mhz anyway... so if you want to hit 3 Ghz you're might need a new board. But see how far you can get your CPU on this board first.

Ram definately was at 133. I will try setting AGP to 67 and get back to you. As far as the PCI slots are concerned, there's not a seperate setting for them in the BIOS, I thought setting the AGP to 66 automatically set the PCI to 33. Is that right? 66 is the minimum speed as it is. Vcore is reported in Core Center as being 1.39v-1.41v, but it's set at 1.5. This review states the maximum FSB is 450 Mhz. Is that wrong? I'm not expecting to get anywhere near 3Ghz. I'd be happy getting close to FX57 speeds, since it's a later batch of CABNE's.

I'll get back to you with the AGP lock issue. Cheers.
 
i would consider checking on the manufacturer's website for a bios update cos i've read about some bios's not implementing the agp lock properly
 
The AGP@67 didn't make any difference. I've got the latest bios version, and I can't find any option to raise the chipset voltage on my mobo. I've got options for CPU Vid and CPU Voltage only.
