Possible issues with F3-12800CL9D-4GBRL

[mithrilrider]

Motherboard: ASRock 870 Extreme3 (latest bios)
Memory: F3-12800CL9D-4GBRL
CPU: Phenom II x2 555BE

When starting up my computer it would freeze on the windows loading screen. I went into the bios and I checked my auto settings. The timings were ok but the speed was 1333 and voltage was 1.645 instead of 1600 and 1.5v. So, I manually put in those and the correct timings (9-9-9-24-2N). Then it would not even post. I looked on here and saw recommendations to raise the voltage gradually. So I did that and had to go to 1.6 to get them to boot. However, I am now getting random freezes.

I used memtest86+ on each stick individually and had trouble posting. Both also froze within a couple minutes of memtest86+. With both of them in I ran memtest86+ for 5 passes. Two were error free. One had 4 errors and two had 2 errors. All of these errors were in Test #5. It did not tell me which channel the errors were in but the addresses were all between 1500mb and 2100mb. I'm not sure what else to try here, or if the stick are bad. Help would be appreciate. Thanks.

DRAM Frequency DDR3-1333
CPU Host/Bus Frequency 240
DRAM Timings 9-9-9-24
DRAM Voltage 1.50V

Then test one module at a time.

I tried this and neither stick would post at 1.5v. I had to go to 1.6v to get them to always boot. Neither stick made it past 5 minutes in memtest86+ without freezing.

Could try raising the CPU/NB by .05 to .1 and the DRAM at 1.55.....what's your vCore?

[mithrilrider]

My vCore is at 1.47 right now. NB Frequency is 2400 and voltage is 1.3. Computer will not post consistently with 1.55 DRAM.

[Tradesman]

Did you raise NB? Should be safe up to 1.6 or so w/DRAM and up to 1.4 on NB

[mithrilrider]

I've had to raise DRAM to 1.6 to have it boot constantly but it was still freezing. Thats a .2v increase for me on the NB over stock. I'll try it at 1.4 and see how it goes.

Did you run memtest on each stick individually?

[mithrilrider]

I raised the NB voltage to 1.4. I rebooted the computer and logged in then left for a few hours. When I came back it was frozen. I didn't even open a single thing after I logged in.

Neither stick will get through memtest86+ at any speed and voltage settings I have tried. The longest a test has lasted is 6 minutes until it froze. I can get through a pass with 2 of them in dual channel, sometimes with no errors, sometimes with up to 4 in Test #5. I'm going to try each one individually and only do Test #5 to see if I can get through it before it freezes.

Have you checked if your settings and changed settings work on anyother system with same specs?

[mithrilrider]

Unfortunately, I don't have access to another system to try the stick out in. Nor do I have access to any other DDR3 sticks to try in mine.

[GSKILL TECH]

Send the memory in for a new kit to see if that works better.

Should I go through you guys or through New Egg?
