I think i did a really bad mistake here.
When ordering my new PC, i should have checked the feedbacks on this RAM kit (OCZ3G1333LV4GK), because a lot of peoples says it makes their computer crash, updates failing and BSODs.
Here are the specs of my new PC, normally:
Board: Asus P7P55D-E LX
CPU: Intel Core i5 750 (with Prolimatech Megahalems + Nexus 120mm fan)
Case: Antec Three Hundred (with Noctua S12B FLX and P14 FLX on the back)
RAM: OCZ3G1333LV4GK (2 x 2gb)
Video card: eVGA Geforce GTS 250 512mb
Sound card: Sound Blaster X-FI XtremeGamer PCI
OS: Windows 7 Home Premium 64bit
I tried so many different things to try to isolate the problem, such as trying a different hard disk, video card, removing the sound card, installing latest drivers, updating to the latest BIOS, manually setting the RAM to the advertized timings and voltage. Nothing worked to fix the problem.
I tried games such as Crysis, Unreal Tournament 3, and a few MMORPGs, the computer SOMETIMES would run, but showing freezes momentarily, and sometimes would just crash the game and Windows telling me something about restoring the NVidia driver.
Strangely, 3DMark06 doesn't crash the computer, but my guess is this 3D benchmark only use the video RAM!
I did ran a CPUMark05 test also, and it DID failed 1 test, and i DID saw the "black screen" or "black flicker" of the screen once.
Also, while trying to update Windows with the latest patches, at the end, it would tell me, for example on 30 patches, it failed to download 25 patches while it successfully downloaded 5 of them, and when rebooting, sometimes it would fail on applying them and "rolling back" and rebooting again.
I tried running the latest version of Memtest86+ on the RAM sticks, and it gave me no error at the end. I also used HDAT2 for a SMART extended test, and no error either.
The NCIX tech support guy told me, at the beginning, that it might be a RAM problem. I did set the proper voltage and timings and everything, it doesn't fix the problem. A friend of mine also told me it might me a RAM problem. But this friend also told me that even if the RAM is ok, your RAM might be in conflict with the main board itself.
So what i did is sent a message to NCIX support, complaining that the assembly and testing team didn't do their job at checking if everything work great. I did paid for that service to be sure my PC would work fine without any hiccup, but the only thing they did is a 3DMark06 test and checking is it boot up fine in Windows, they didn't checked if the RAM is ok as i asked them to, they didn't install any Windows patch, they didn't tested the system with a real game. They could have done this and detected the problem and told me about it before sending the whole thing to me!
I also asked in the message, if possible, to replace the RAM for a 2 x 2gb RAM kit of Corsair CMV4GX3M2A1333C9 which is a lot more reliable, and i did checked the Corsair website and it's garanteed to work on my board!
Previously, i did asked on the OCZ support forum if this RAM kit is supposed to work on this PC, an official OCZ tech support guy told me that it will work, but i think this RAM is unstable or get in conflict with something on this board. As i said before, this RAM seem to have a lot of troubles to a lot of peoples.
The computer seem to work ok in Windows, but the moment i try to update it, try to play a 3D game...it just crash. Before formatting the hard disk, i even got a few blue screens. Trying to install Windows XP 32bits on this PC, during the installation, after booting the install program, it gives me a blue screen. Also, once during the Windows 7 installation, it gave me an error saying it couldn't continue installing Windows. I had to restart the install process to install it.
I remember something similar happening with this Athlon 64, when i tried to add more RAM, i bought a set of 2 x 1gb RAM sticks from someone, and it's a known brand, called Transcend, well it DID worked, but i occasionally got BSODs for no reason...i removed those RAM sticks soon after and no more BSODs, since i had 2gb already, it was no big deal.
So what do you think? is it really a RAM conflict problem? Should i get them replaced by the Corsair memory?
