Kingston has a very good record of compatability, especially you are using a 4G kit. I would suggest you to check your power supply, or change it to a more powerful unit to try if you can get one.
There's a 500W PSU in the machine. Brand: Thermaltake. I don't think going higher than this will make a difference? All the parts are brand new...
DDR3 compatibility is likley your issue. Could have a bad second module or bad slot (swap em' to check) , but I'm betting it's compatibility issue. One other possibility is power supply but if it's a quality one, i'd still suspect RAM compatibility problem. Wait for a BIOS update or get different RAM. Not much of a soultion and why i've returned some DDR3 products.
Thanks a lot burfadel and starams5 and all of you for that matter for your explanations and help! This can definitely help a lot of people out there. The power supply wasn't the problem. It's a brand name PSU. It was definitely the ram. It was correct (1.7v ram) so I downgraded it to 1066mhz, got it to run but it would freeze. So I indeed got 2 X KVR1333D3N9/2G and that worked like a charm. Thanks again!
No worries! You wouldn't be the first to have memory problems with the core i3/i5/i7's due to the memory voltage. Its a good thing it didn't work properly, apparently anything higher than standard stuff's the CPU (this can be read online).
Do you mean stop error and reboot? Sounds like it. Probably BSOD'ing and rebooting, because Windows is reporting a corruption error. Reseat the RAM and try again.
The problem was that the memory wasn't compatible RJARRRPCGP. Got new memory sticks and voila! it worked. Thanks
Yeah it vitally important to get the right DDR3 RAM depending on your system, hopefully soon manufacturers just make Core i3/i5/i7 compatible RAM as they should work on all DDR3 systems.
