I have an Asus P5Q Premium motherboard and have 4GB (2x2) of OCZ DDR2 PC2-6400 Vista Performance Gold 4GB Dual Channel ram which works fine.
I have upgraded to Windows 7 Ultimate 64 bit and as I have another 2GB (2x1) of the same ram (OCZ Gold XTC OCZ2G8001G (2x1GB)) I thought I would be able to use it with the 64bit OS, but not so.
Both sets of ram work fine seperately but when I add the two 1GB sticks the PC starts (fans , lights, HDDs etc) but it won't boot or go into the BIOS. All settings in the BIOS are set to AUTO.
Although the ram is supposed to be the same speed, CPUZ reports the timings as different.
2x1 as 5 5 5 15
2x2 as 6 6 6 18
I have tried setting the timings manually in the BIOS to both sets of timings without success.
Although I have built a few machines in my time, I'm a newbie when it comes to ram timings.
Any suggestions would be welcome.
Thanks
