Re: Fix for DDR 3 rowhammer corruption issue found!
Interesting. I have to say, I've only ever had these types of issues on Corsair RAM. Never seen it with Kingston or any other brand before.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Fix for DDR 3 rowhammer corruption issue found!
Wouldn't it be dependent on the RAM ICs then, and not the brand? Kingston and Corsair use different brands AFAIK, but Crucial always uses Micron (Because Crucial is Micron). Maybe he was refering to the hammer test failing on all DDR3?
And then I'd be curious about DDR2..."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

Re: Fix for DDR 3 rowhammer corruption issue found!
That setting was known as tRFC in the DDR2 days. And yes, i've had the same kind of issue with Corsair RAM. Hence why i reverted to buying the cheapest RAM i can find for the desired speed. My first time buying Corsair memory was also my last.A working TV? How boring!Originally posted by PeteS in CAComment

Re: Fix for DDR 3 rowhammer corruption issue found!
To me, it looks like all motherboard makers set the wrong DDR 3 refresh rate interval setting by default.
It looks like the default setting results in the RAM not getting refreshed enough.ASRock B550 PG Velocita

Re: Fix for DDR 3 rowhammer corruption issue found!
This problem occurs with *all* DDR 3!
The only possible exception is with the new HyperX Savage DDR 3.ASRock B550 PG Velocita

Even DDR3 ECC? My desktop's running UDIMMs now and I'd imagine something like this would be flagged by the ECC.Comment

Re: Fix for DDR 3 rowhammer corruption issue found!
corsair tends to customise ram for performance.
pushing it to the edge.
explains increased sensitivity to these type of issues.Comment

Re: Fix for DDR 3 rowhammer corruption issue found!
In that case there's a utility to re-write the SPD... It can do this in place with the RAM installed. It used to be free, but now he's charging for it."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine!

Re: Fix for DDR 3 rowhammer corruption issue found!
No. Not all DDR3. There are more exceptions.Originally posted by RJARRRPCGP View Post
There is also ECC memory to consider.
From what I remember reading when Rowhammer was first discussed this is more a worry for Linux users rather than Windows as most Windows users run as admins anyway.Last edited by diif; 05-19-2015, 12:13 AM.Comment

Re: Fix for DDR 3 rowhammer corruption issue found!
Hm, I've never had issues with using DDR3 so far, but I haven't done any fancy memtest things or the like.
Could it be improper design of the memory chips, or the PCB itself? (High speeds need controlled trace length and impedance...)

Re: Fix for DDR 3 rowhammer corruption issue found!
I'd assume it's just a symptom of having everything so densely packed inside one IC.Comment

Re: Fix for DDR 3 rowhammer corruption issue found!
Micron is just as guilty, if not more guilty, with their Crucial division.Originally posted by kc8adu View Post
Crucial with their Ballistix series, loved to overvolt DDR 2 to 2.1 V or 2.2 V, IIRC.
Micron's D9-family DDR 2 chips reportedly failed like XBox 360s!Last edited by RJARRRPCGP; 05-23-2015, 06:12 PM.ASRock B550 PG Velocita

Re: Fix for DDR 3 rowhammer corruption issue found!
all I know is this. I've used GSkill for all my customers. Only bad stick i've had was DDR2. No stability issues related to memory on any of themCap Datasheet Depot: http://www.paullinebarger.net/DS/
