System fails Prime 95

Tags:
Last response: in CPUs

Hello,

I recently built a new system containing the following components:

CPU: socket 1155 Intel Core i5 2500
Motherboard: Gigabyte GA-Z68X-UD4-B3
RAM: 4GB Patriot DDR3 1.5 V
Video Card: XFX Radeon HD 6870 1GB
Power supply: Enermax NRXN 600 Watt
Harddrive: 2x western digital caviar black 500GB in RAID 0

I have installed windows 7 64 bit on the machine, however when I run prime 95 the system will freeze right after starting the test. I can get the test to run for about 30 min if I disable all the CPU cores except one.

Does this mean that the CPU is defective? Are there any other tests I can run?

At first I thought it was the RAM so I took it back to the store and they tested it with an AMD system and it ran Prime 95 just fine. At this point I think its either the CPU or Mobo, but I have idea how to test.

Any help is greatly appreciated.

Might want to download CPUz, run and look at the two memory tabs. First tab shows what the memory is running at, the 2nd tab shows what the memory can run at.

So, is your memory being detected properly and running at the correct voltage and are the CL values correct. If not correct and as henydiah indicated download the ISO for Memtest86, create a bootable CD by using the ISO function (Can NOT simply copy to CD. Boot to cd and run test for 4->8 hours.

ok so i ran memtest86+ and it found errors. I returned the RAM bought two new sticks of mushkin 1333mhz DDR3 4GB ram.

Now when I run memtest86+ i get even more errors than before. Did I just get another defective set of RAM, or could it be a CPU problem?

I wouldn't go for Mushkin. Never been a fan of their products. Corasir, GSkill and, although I wouldn't buy them, Super Talent are much more reliable.

If you still get errors from Memtest 86+ after trying three brands then its a possibility that its the motherboard. I doubt the CPU would be bad since, well its pretty hard for a CPU to be bad these days.
