Unstable memory? need held diagnosing a problem.

post #1 of 6
Thread Starter 
Hello, theres something wrong with computer and have a few question.

I'm having is really bad crashing while gaming. This has happened on two of my games recently. When the crash happens my games video starts to flash erractically followed by the game itself crashing and which sometimes also crashes steam. One time my whole computer crashed and I couldnt get into the task manager to close the processes that werent working. I had to hit the reset button. Does this sound familiar to anyone?

Recently I've made changes in the bios for overclocking the CPU and setting the ram to 1600 speed.
For now I will go into the bios and set everything back to stock settings.

here are all my current setting changes, hardware specs in my sig.

1090t overclocked to 4Ghz
Multiplier x20
CPU voltage 1.45 volts

Kingston HyperX ram, x2 DIMMS DDR3 8GB
speed 1600
DRAM Frequency 803. MHz
DRAM voltage 1.64
timings 9-9-9-27
^
maybe my ram is crappy? I also have 8GB worth of ADATA ram, 2GBper stick that I can try.

I've been trying to download maxxmem2 but it looks like their site it down. I can download it from other sites but my virus software says its installing malware when I run it. Also the version I have doesn't give me Memory Latency.

Any help is appreciated.
Thanks,

Matt

I'd start by running Memtest86+ to check the RAM for error.

When OC'ing you should always stress test the system with Prime95, OCCT, Linpack or similar to see if the CPU/GPU temps are good under max load - similar to heavy gaming. If either the CPU or GPU gets too hot it can cause data errors and crashing. I recommend the latest version of "Core Temp" to monitor the CPU core temps during stress testing to see if you have a thermal issue.

OK thanks. I will try to run memtest. Its looks a little complicated that I have to make a bootable disks and all but i'll figure it out. I may have an easier time making a bootable floppy seeing as I actually have a floppy disk drive that I can temporally install for that purpose.

Concering CPU temps, I thought it was fine although I never did run a 24 hour prime95 stress tests. I frequently bring up CPUID HW monitor to check cpu temp right after gaming and temps on the CPU seem perfectly within limits. This picture shows some kinda awesome cpu temps when running prime 95 with the cores loaded but I only ran it for ten minuets to get this picture. I did have the air conditoiner in the room cranked and all computer fans turned up though.

If you have a usb flash drive you can download the usb flash drive one. It will format the flash drive and make it bootable for you. Thanks

Cool thanks, maybe I'll give that a try.

I was having this issue on my i5-750 Oc'd to 3.8ghz and 2 HD 6670s. The problem has been helped by boosting my PCI-e Frequency in BIOS. Take it one step at a time, but it will help to sync up the CPU Speed, vs the Mem Speed, vs your 6870's bandwidth output.

Check this out for PCIe Frequency explained.

EDIT: Oh ya and Frequency is listed under the Ai tweaker Menu, and PCIe Frequency will only show if Ai Overclocking is set to manual.

Edit 2: You might also look at your Ram Voltage. I've Heard of people benefiting from boosting 4gb sticks of DDR3 to 1.66v-1.68v for better stability.
