Please help, Unstable RAM

Recommended Posts

Hi,

I've been working on this OC for months now and I'm having problems getting my RAM stable. My system is 12 hours Prime stable but I get BSOD's during games, saying theres been a problem with the memory and it has to dump.. Putting my system back to stock fixes the problem so it cant be the actual RAM. I have tried heaps of different dividers and tried loosening the primary timings to no avail. I've tried increasing the voltage to the RAM to 2.7v. I know very little about the secondary settings so I dont really know what I'm doing there. The settings in my sig are different to my current, will fix that soon.. I've even slightly underclocked the RAM and stock timings to still get BSODs.. Please help..

 

These are my current settings..

Do you know what chips are on your gskill? Are they TCCD?

 

For my Gskill TCCD's i use the following timings (also to get the stress from my memcontroller). My timings are behind yours okay?

 

DRAM Configuration Settings:

DRAM Frequency Set............................ - 140=RAM/FSB:07/10

How do I find out what kind of chips they are? I'm trying those settings now. Also I notice in the Genie bios settings that:

DRAM 2.5V Voltage....................2.68V

Is that supposed to be like that?

 

Also, how do i embed that text that i attached like you did:p

 

EDIT: Well its booted ok so now I'm running some memtests, and I'll run through some other tests if that passes:)

Another thing I've noticed is CPU-Z doesn't always report my RAM MHz depending on what divider I use.

The embedded text is simpel. I just copied and pasted the text in your textfile into this window.

 

About the vddr, that's kinda strange, but it also could be a good thing :-) This means that your board overvolts the vddr, but you should pay attention no to overvolt your ram.

LOL, yeah, that was simple... prolly why I didn't do it.

Is it going to kill my RAM having it over volted like that? its nearly 0.2V!! Why would it do that? Could this be causing my problems? Should I RMA it?

I *seem* to be stable now, I'm all good in stress testing, But I always have been, there are two games that generally caused the BSOD's, WoW and Empire Earth, so Ima play a heap of them over the next couple days and see how it goes.. Please keep checkin the thread, thanks heaps for the help so far. So heres my updated settings:

So, I'm still struggling with these RAM settings. Still getting BSODs. I've even tried setting my FSB to 300, x10 CPU multi, and 2/3 RAM divider, which set my RAM back to stock, whitch actually worked great but my system would boot to the part where it 'verifying DMI pool data' and 60% of the time would just reboot again. Any ideas on this? My current settings are:
