Solved Windows 7 does not boot with 4 ram sticks (16gb)

[TBoyd]

I'm no overclocking guru, but from experience I've found that overclocking is very touchy (no matter what brand of mobo) when you have the max amount of ram installed. When the CPU is strongly overclocked, ram will barely run at stock speed. If you push the ram speed up you're limited on the CPU speed options.

Someone please correct me if I'm wrong. - Still learning.

I think it depends on what you are running. An intel system is a completely different animal than an AMD system. A Sandy Bridge is different still. I'm a long way from a guru on overclocking, but I have had all 3 systems and each is different. Amd systems at default sets ram, no matter what kind you have, to 1333 9-9-9-24. Adjustments have to be made to run it any other frequency. Intels work diffetent. Sandy Bridge, you are not overclocking the CPU per se, you are OC the turbo function.

I think that is maybe what is happening here,
Whoops I am talking rubbish, sorry just got up and still asleep lol
The RAM needs to be set to auto or 1333MHz

Pooch, I think you are right. CPU overclocking is set to manual, he has set the dram frequency and the target frequency on top of the screenshot tells alot.

Yes that is what I think, but I really do not understand why the RAM has been keyed in so low, unless its a leftover from the original problem.

Agreed. Most people want their ram to run faster.

I set everything back to auto in the BIOS and loaded the systems normal settings. The cpu is running at 3.2GHz and the dram is @1333 9-9-9-24. The M5A88-V EVO motherboard comes with some overclocking and systems utilities. According to the manual, You can push the cpu from 3.2GHz up to 3.9GHz and the ram up to DDR3 2000 (O.C.) but I found out the system doesn't boot or it becomes unstable. I'll leave it set to normal. Once I learn more about it I will change some settings. Thanks to everyone for helping.

I'm glad you got it running stable. As far as the ram. I think what it is saying is that if you install DDR3-2000, the machine will automatically set it to 1333, but you can overclock it to get your DDR3-2000 ram to run at 2000. 1333 ram will not run at 2000. It is good that you have it stable now. Good luck.

Oh ok, I get it. thanks.

Just because your BIOS allows you to overclock your system, it doesn't mean to say that you can or that you will be able to upto the limit permitted by the BIOS. Overclockability depends very much on your hardware (CPU/RAM), and you will find that some are more tolerant to overclocking than others.

Dwarf, to emphasize your point, I was reading on Overclockers net when the 2600K's first came out. They were seeing how high they could overclock them. They found that some were better than others and started making lists of batch numbers. They narrowed it down to which batch numbers to look for because some overclocked much better than others.

To narrow it down even further, even CPUs that originated as neighbours on the same wafer during manufacture can have very different overclocking capabilities.

Yeah I found that out the hard way . the system is ok for now.

Yes all the CPU's on a wafer are tested, those that pass high tests will become the i-7 extreme or Phenom X6 Black Editions. those that fail some tests will become i3's and Athlons or Semprons.

This is why the high end CPU's cost more. Fewer of them meet the criteria per wafer.

Good!! I hope it stays that way
Did you read the link I sent you? It will help you too overclock your system but you have to do it slowly, in steps, testing all the way.

Not yet, I will when I get home. Thank you.

Sorry, actually I did read it. That's where I got the link to the article talking about AMD processors and DRAM settings.
