This is the Support Log from Giga-byte. Keep in mind that both Corsair and Gigabyte list the 8500c5 as compatable memory. The discussion starts from the bottom and goes up to the top.
Ive contacted Newegg about the issue. I have no doubt they will step up and help out, but this is a bigger issue, and its not fair for NewEgg to keep picking up the peaces.

Question : You must be kidding me...
So you advertise support for memory that isnt supported. Even at 800mhz 4-4-4-12 timings lead to crash and unresponsive computer.
Ok, so now your company has done something wrong, how are you going to fix it. Are you going to provide me a product that will do what you said it will do? Are you going to refund my money for the memory I bought?
The answer you gave me is fair, however you have provided me with little or no way to compinsate me for your companies mistake, miscommunication, misunderstanding, and failure to meet product promisses.
Do you have a product that supports this memory at 1066? If so, then it is time for you to contact NewEgg and get them to get me that product, as an exchange. If you do not, then it is time that I move to another manufacturer. Again, this requires you to contact NewEgg, pay for shipping of the product and to make it fair between you and them. In addition you will have to pay for my return shipping costs.
However I will have to work with NewEgg on this, so that I can exchange this product. You have cost me ALLOT of time and frustration.
I will be contacting newegg on this issue.
Answer - 410775
Answer : unfortunately the motherboard is not guarantee to support 1066 memory, only up to 800mhz.
Response
Memory On Default (optimal) settings
399,9mhz
FSB DRAM 2:3
Timings
5-5-5-18
SPD - there are 2 entries
@400mhz
CAS# LAT 4.0
RAS # to CAS # 4
RAS Precharge 4
Tras 12
TRC 22
Command Rate 2T
@533mhz
CAS# LAT 5.0
RAS # to CAS # 5
RAS Precharge 5
Tras 15
TRC 30
Command Rate 2T
Now 533 has slower timings, but is Much faster overall when set to 533mhz. The lkink Bellow has my memory settings. I cant open it without submitting first, or it may crash.

Answer : Hi
what is the model # of the memory you have and can you provide us with an link for the memory. Is this the same one as you have from the below link?
http://www.corsairmemory.com/corsair/products/specs/TWIN2X2048-8500C5.pdf
Also please download the cpu-z software from www.cpuid.com and let us know what the memory clock speed is detected at on default values.
Thank you
Question : The DDR rate is actually 4 times the FSB on the Core 2 duo.
Hence a 266fsb with a 4 multiplier has a 1066 rate (it actually comes out to be 1067)
I have a X6800 so my Multiplier is 11 and all core 2 duo processors have a stock 266 FSB.
A 533 FSB would require me to run my processor at under 6, without overclocking the processor. And would result in a very high overclock on the motherboard. Hence your answer is a bit off key, and wrong.
The problem has been in some of the language. Gigabyte marks a 533 memory speed at stock values as a 2 x memory multiplier, while many other people consider this to be a 1:1.
What matters to me is that the 266 fsb with a memory multiplier of x4 (1067 mhz) a voltage of +.4 and a timing of 5-5-5-15; will not work. If you look up on corsairs website, and look at the 8500c5 1gig x 2 (2 gig total) memor y modules you will see that these are the specifications they have set for their memory.
You would also notice that I had this running fine on a Asus P5B mobo, on stock settings. I also would like to note, that I am NOT overclocking this motherboard for any of these tests, and once again would like to state that I am running everything on Optimized settings except for manually setting the above.
Now I do not know what the other 4 memory settings should be set to after the 5-5-5-15, and cant seem to find this information, so I leave them to auto. Your Mobo reads the 8500c5 as 800 MHz memory, and yet you list the 8500c5 memory specifically as supported memory in your list.
I have stated that I dont Overclock this machine over and over again, and as you can see, I know what is going on here. I also dont understand why I havent gotten a single answer or suggestion from Giga-Byte, and continue to get a dance around the topic.
If it is a fundimental flaw in the design of the motherboard then I will have to return the MoBo back to NewEgg at your expense. If the problem is BIOS related and is a result of my specific setup (a X6800 with Corsair 8500c5) and you can acknowledge that their is this problem and that it is beign worked on and will be fixed, I will be patient.
I am not happy about the idea of changing Motherboard companies again, due to lack of support, and expect more from Giga-Byte then I do from Asus. I feel a sinking feeling that I am going to be stuck with finding a product that supports my hardware, and once again having to go through the new mobo rutine.
Drain Water Supply, unhook/cut water hosing, remove motherboard, remove waterblock from Mobo, remove CPU, replace hardware on MOBO to protect CPU, Add Waterblock and CPU to Mobo, Put new MOBO in case, Rewire the whole case to fit the new MoBo, re-route water hose on new motherboard. Add more non-conductive, non-corrosive liquid, check for leaks on another powersupply (1 day later), add a floppy drive, Re-install windows, update drivers, install all software, etc...
Please dont waste my time anymore. Tell me what to do and I will do it. If your product works with this configuration, then go down to your lab, install a X6800 processor on the 965 express GS3 product with the $400 Corsair 8500 c5 at 1066mhz with memory timings of 5-5-5-15 and a +.4v and then try and load the product up with windows. If this works, contact me and tell me what to do... If it doesnt, then tell me it doesnt, and then say... "We are looking into it". Then Please keep me informend. I need to know the results of the research that will come from this.
Thanks
Mike
Answer : Hi
Please note that you are running ddr which doubles the data rate. For an 1066 processor it should only be clocked at 533fsb under bios which operates it at 1066.
Anything higher is overclocking the fsb which the results from that are not guarantee
Thank you
Question : When I push Ctrl+F1 and then the MIT option in bios... Load Optimal Settings, it shows the memory at 800mhz, though it is not enabled for change.
I dont know what this CPU-Z software is. I have the CPU OC program and the iCool program.
I dont know if their is anything else I can do. Your memory list shows the 8500c5 under the 800 Mhz list. You dont even have a 1066 mhz list.
This memory was very expensive, and I bought the board because it was listed as supported. Have you even gotten it to run at 1066?
Answer - 408601
Answer : At default spec how fast does it detect the memory at using CPU-Z software?
Question : Its stable until I set it to 1066 Mhz.
I will overclock, and it runs great... Only problem is that the machine farts out as the memory reaches 1ghz!
A change to 1066 at default settings will have it freeze, requiring me to reset the bios to get it going again.
Answer : Hi
with no settings changed and you loaded the defaults under bios will it POST and operates properly?
Question : The machine will not post, and will freeze with your default settings and a Memory Voltage of +.4v, a Memory Multiplier of 4, and either auto or 5-5-5-15 memory settings. It is not overclocked. It MAY have run under the default f4 bios, but I set thoose settings up, then I almost immediate flashed it. After flashing the Bios, the machine would show your Gigabyte is great screen, but nothing would respond.
The Asus ran the machine at 1066mhz.
I love the Giga-Byte. It is running great, and I am able to adjust settings on it... The Asus P5B lists X6800 as a compatible CPU, however it is not. It runs only on default settings.
Answer : Hi
with the conroe processor only 266mhz is required to be set, anything higher would be consider overclocking and may not be fully stable. At default specs with no settings changed any issue?
Question : I have Corsair 8500c5 memory, and am having problems setting it up to run at 1066mhz. I raise the memory voltage to 2.2v, and then try to raise the memory multiplier to 4. It fails to post and all I get is you GigaByte window.
I own a Asus p5B, that didnt seem too compatable with my system, it ran everything fine until you tried to change the settings. Then it would fail Prime95.
When the Giga-Byte fails to post due to a incompatable change in Bios settings, the only way to fix it is to take out the CMOS battery and then short hit the jumper.
Is their a better way to revert to the last BIOS settings on this board. I know that if the ASUS failed to post, all you had to do was turn off the power on the PSU and then it would revert back. The Battery location on this board is in the worst place I have ever seen. And its VERY hard to get too and replace. It can take me 10 minutes to get the thing out and back in.
Thanks
Mike
