First Overclock ~ A Failure

[Nick R]

I've just built a pc with the following specs;

2.4GHz G0 Q6600

2GB Corsair Dominator DDR2-1066 2.1v 5-5-5-15

ASUS P5KC (P35 Chipset)

XFX 9600 GT XXX 512MB/700/2000

580W Hiper PSU

OCZ Vendetta CPU Cooler

2 IDE Hard Drives (40 gig, 160 gig)

SATA DVD Drive

My first issue is the fact that the ram is running at DDR2-800 1.8V 5-5-5-18. I attempted to clock it up to the rated specifications but after saving, the machine reboots but the monitor doesn't recieve a signal. If I reboot again then I get the message;

Overclocking Failed! Please enter Setup to re-configure your system.

Press F1 to Run SETUP

Press F2 to load default values and continue

Do you guys have any idea what the issue could be, any help would greatly be appreciated.

Thanks,

Nick.

The RAM-clock problem is very common, as far as I know, it was the same for me. Did you set the voltage and timings manually?

 

[nepas]

have you set the ram voltage first?try only one stick of ram

 

[Nick R]

Ok, just tried setting to 2.1 rebooting and then setting to 1066 but on the second reboot I had the same issue. I'm trying with 1 stick now.

There is nothing to worry about though mate, this is a common error for overclockers.

Just go into the bios and try again.

Set voltages manually, CPU and Ram.

 

[Nick R]

Exact same issue with just one stick.

Have you tried giving the NB voltage a little nudge. This sometimes helps with memory problems.

 

[Nick R]

Ok, noob question, what's the default NB Voltage?

 

[w3bbo]

Load default settings (everything on auto) reboot, then check the hardware monitor in the power section - it should tell you what voltage you NB is running at with stock settings.

Harsh words. I`d be more inclined to say it "didn`t work", but we`ll get it going

 

[Nick R]

The only voltages I get in the Hardware Monitor section are just the vCore and the 3.3/5/12v's.

The options I have for NB Voltage are;

1.25

1.4

1.55

1.7

 

[Nick R]

I've tried 1.4 on both the NB and the front side bus termination to 1.4 (on a whim) but that still didn't help. It runs at 890 MHz (closest to 1066MHz) absolutely fine.

Are the memorysticks SLI-ready? If so, there should be an option in the OC-section of the BIOS called SLI-ready memory. Try setting it to "Expert". When I did it, it set the RAM automatically to 1066. Anyway, if you don't do this, you still have to set the timings manually.

 

[Nick R]

Unfortunately not.

Well I clocked the CPU to 3.2 GHz (400x8/1.425 in BIOS 1.375 in Windows) and have the ram running 1000/2.1. OCCT just failed 4 minutes in so I'll up the voltage a bit more, it drops to 1.25 with OCCT running.

Don't change the multiplier, just the FSB. The Q6600 works best with the standard multi.

Sucks Bro better luck next time.

Have you flashed the BIOS at all? It could be some problems with an older BIOS, as far as I know, it should be able to clock well with the memory running at their original speeds, and with the multi at 9 you should be able to draw some nice nice clocks out of it, with only the smallest change in the vCore.

 

[Nick R]

I currently have it running at 320x9, I was going to have another go later today. vCore is currently set to 1.425 and runs at 50 after an hour of stress testing.

Now running at 1.35v 356x9, 50C under load. I have some major disk issues with my ancient IDE drives at the moment so I'll have to sort that out before I can do anything else.
