Hello all.

I have just completed my first build and much to my dismay the rig will not even POST. Here is the spec:

Case: Thermaltake VA8000
MOBO: Gigabyte GA-MA770-DS3
CPU: AM2 Brisbane 5000+ Dual Core 2.6GHZ
Video card: EVGA GeForce GTX 260
RAM: G.SKILL 4x1GB DDR2 1066
PSU: PC Power & Cooling S75QB 750W
Monitor: Hanns.G Hi-221DPB 22" LCD
HDD: 250GB Seagate SATA
optical: ASUS DVD-ROM

And it looks like I should've done my homework before buying that RAM: http://www.gigabyte.com.tw/Products/...ProductID=2722


Quote:
* DDR2 1066 is supported with combination of AM2+ processors and DDR2 1066 memory modules, please refer "Memory Support List" for detail memory support information.


So here are my questions:

1. Is it normal for the system to not even be able to boot into BIOS in this situation?

2. If so, is there any way to get the system to boot into BIOS without having to either get new RAM or new CPU? People have said that 1066 is just an overclocked/unstable version of 800...so maybe it's possible to "underclock" it back to 800 if I can get the system to boot into BIOS?

Thanks for your help!

1. Make sure everything is plugged in properly.

2. take out 3 sticks of ram

^ Yes, boot with only 1 stick. If this works, you can get in and set the voltage, timings, speeds, etc to make all 4 work correctly. You may have to up the voltage slightly beyond spec, or loosen the timings to get all 4 sticks to work.
You know it would have been far better to buy 2-2gig sticks, right?
