Hello,

My daughter got a computer as a christmas present yesterday. Since I couldn't afford a completely new computer, I have used some old parts and some new. All parts works. What I don't know is if there is som campatible issue with the memory.

I build the computer and put in two sata drives and the above parts. The first time I use Kingston ram 4gb dual channel 1333mhz instead of the corsair above. I installed Windows 7 and my daughter have used the computer a couple of days now, playing WOW and other things. It has worked perfectly. Second time I remove the memory and install the above from corsair. It also worked perfectly at the beginning. I don't know for how long time, but an hours, two hours or so. Then she left the computer. After we had seen a movie she went back to the computer and it had shut down for som reason I don't understand. I tried to turn it on, but nothing happen, as if it was dead. I tried several times without luck. I opened the case and removed the powerswitch cables and inserted them again. Then I closed the case and started the computer. Now it start but I get error on post sceen: Overclocking failed and it tells me to get into bios to change configuration. I press to get into bios, but it hangs. I restart and Windows starts. Now it works as it should.

But why the error? I haven't tried to overclock and the only thing I have done in Bios is to change the boot sequence to be able to install from DVD. Since the problem arise after installing the ddr3 8gb dualchannel 1600mhz, I guess the problems lies in new ram. It is 1600mhz, but doesn't show 800mhz, instead it show half of 1333 (667mhz).

I have read something about MB that doesn't support 1600mhz get default 1333, but this MB does support 1600mhz and the frequency should be 800mhz with dual channel. The memory is inserted correct in first and third slot with the same color. Are these memory incompatible with the MB anyway?

From the beginning we bought the corsair memory to my boyfriends computer, a gigabyta 890fxa-ud5, but the dram frequency only show 667mhz. We searched with google and did find out that his MB didn't support 1600mhz at all. Therefore we tried to use them on the Asus M5A87 instead.

Shouldn't we use the corsair memory in any of the two above Mobo? Can we damage something? Are there any settings we should do? Clear cmos or in bios reset to default?

I am worried the computer will shut down again, because there must be something wrong when it shut down the first time.

That mobo will support memory at 1600MHz only when Overclocked. Firstly.
The Processor too support 1333MHz by default, so you will get a downclocked mem of 1333MHz.
The PSU should be sufficient enough to run the rig.
Now you can have just 2 major problems, one is a Bad RAM or a malfunctioning PSU. During the shutting down of the rig, it could either be overheating of the Mobo, or the fluctuation in power.
Yes, you could try a BIOS reset and try to boot into windows.
A good Idea would be to keep a watch on temps and currents in the rig.
You can use a free utility called HWMonitor to do that if you want.

I noticed that I have bought the right memory to my boyfriends computer with mobo ga-890fxa-ud5. The model of the memory is CMZ8GX3M2A1600C9 and not cmx8gx3m4a1600c9. His motherboard are listed as compatible on the corsair site. We have installed them in his computer again, since my daughters computer did shut down again. Her computer has run a lot of hours now and I hope it will continue to do so. If it will shut down again, the problem should be the power supply, since I'm sure the memory, motherboard, harddrives and the cables are function good. The graphic card and cpu I can't know for sure, but both are totally new products, so I suppose they are ok.

Anyway, we have another question. My boyfriend wants to make the memory to run at 1600mhz and not 1333mhz and he is planning to change settings in bios. I want to know how to do this? Can he damage something? Will he gain some performance? Advice?
