So...I took a Q6600 from my computer (easily overclocks there), and bought a Gigabyte EP45-DS3R, OCZ Vanquisher Cooler, 4 x 2GB's of OCZ Reaper PC2-8500, 580W supply, basic Nvidia card (at his request - the computer is for a sound technician), and 2 x 74GB Raptors....it all works FINE, but if I try to raise the FSB to 286MHz, it fails to boot, and the bios eventually resets to a failsafe condition.
I have tried:
Raising the CPU voltage 100mV
Raising the RAM voltage to 2.1V
Fixing the PCi / graphics to 100MHz (is this correct?)
There are so many overclock options, and I have no time to 'learn' this board before I have to hand it over in about 12hrs.
If anybody out there can help me reach at least 3.2GHz, you will surly be rewarded in Heaven
Remember - this CPU overclocked beautifully in my other computer.
If it is, roadrunner197069 is right. It takes 2.1v stock to get 5-5-5-18 timings. 4 DIMMs are harder on the board. You will probably have to up the RAM voltage to 2.2v to run all 4 DIMMs. You might also have to up the Northbridge voltage to get all 4 DIMMs to run. You should really do more research before trying to throw a computer together for a customer.
Next time dont sell a overclocked computer, without knowing what you are doing.
I haven't seen anybody mention the CPU as the problem. It looks like either the RAM or PSU. Have you run Memtest86+ to test the RAM? You're also just asking for trouble using a POS no-name PSU. There's a very good chance of it blowing up and taking other hardware with it. I would see if you can delay deliver and get a quality PSU from Corsair, PC Power & Cooling, Seasonic, OCZ, Antec, etc...
P.S. Sorry for jumping to conclusions. We see a lot of noobs on here trying to pass their old hardware along to some unsuspecting sucker. I do stand by my comment about doing more research before doing a build for a customer, however.
Shortstuff: yeah no probs. But, he can't wait, at all, we had delivery delays already, so I'm tempted to hand it over @ stock settings until I can negotiate the purchase of a better quality supply with him...
I just updated the bios this second, and just about to boot.
The first thing I would check in addition to the PSU is the RAM. Ideally you would want to run Memtest86+ for at least 8 hours, but I know you don't have that much time. You should really run it for at least a pass or two before delivery. If it comes up with any errors at its rated timings and voltage, you might be dealing with defective RAM.
Well since I build PCs as a side income, I will give you some friendly advive from experience.
Never ever buy generic PSU's "Especially if you want to run a dedicated GPU, and/or overclock!"
The problem is probably the power supply. But just to be sure try your ram @2.2v and try the CPU @ 1.5 just to see if it boots. If it does fine tune the voltage. If it dont you need a new CPU, and it may kill the whole system if left unchanged.
