Ram speed crash windows

[BlackGrim]

Before this i have problem with windows 10 crashing i thought it was because of sata mode it actually because of ram speed so why my ram can only run at 667mhz and crash when it run 800mhz my ram is PC2-6400

because it's unstable. Maybe it degraded overtime (or the CPU's memory controller), maybe the board's degraded so it's not supplying power as expected.

What CPU is it?

 

The modules are dual rank which present some extra load. They're mismatched which probably wont help either. What timing was it trying to use? Maybe the mobo wasn't picking the slowest of the lot. Try manually setting 800 6-6-6 1.8v?

So what should i do?

run it at 667MHz? It cant get that much slower after that

I want run it at 800mhz there are reason why i buy PC2-6400 ram maybe it wont work since i use mismatch ran?

Ok, not familiar with how those ran. You can still try the manual timings like I suggested, but note I edited it to 1.8v as all modules should support that at the loose timings. If that still doesn't work, just go with the lower speed. I'd rate the faster ram as a general "nice to have" but wouldn't worry about running slower on such an old system.

Weird 1.8v on ram voltage seem to work fine for atleast 5 minute and it crash at least something than usual 1 minute in windows and immediately crashing should i increase the voltage?

But i afraid it will kill my ram

Did you also set the timings manually? Up to you want you want to try. As suggested I'd just drop to 667 and leave it. Unless you have a particular need it isn't worth worrying about.

Yes i manually set the timing i think i just leave it be rather than risking breaking my ram thank for you help

not sure, tho I know the offical max supported memory frequency for this CPU on AM2+ is 667MHz, more is considered an overclock
