Need help with RAM, new GSkill Memory not working... - Page 2

post #11 of 13
Thread Starter 
Actually you guys won't believe this - I FINALLY GOT IT WORKING!!!! doh.gif

I had the RAM boxed up, I was about to RMA it. But I went through some reviews on New Egg for the RAM, someone has the same exact board and had issues with it, G Skill answered them and posted all the timings / voltages. I decided to give it one last go - I duplicated their numbers and now the RAM is running stable, just finished three matches of BF3, couldn't play for more than three minutes before. Stress tested in Windows Diagnostic Tool and Super Pi, no issues! I don't want to get my hopes too high but right now everything "feels right" with it. I can tell if something is wrong, FPS/lag, even when Windows starts up, everything seems OK.

For those who ever get this RAM or find this on Google here is the solution. First off, with "quad" channel, when using four sticks, they stated specifically AMD doesn't natively support more than two sticks of RAM running at 1866Mhz (and this was for someone who was using a high end bulldozer CPU, the 8150 I believe). Running two already is considered overclocking, in fact anything past 1600Mhz is. I was trying to push all four channels at 1876Mhz or so, a little higher due to my overclock, but even with the FSB dropped so it would be at 1866Mhz it wouldn't run. I took it down to around 1600Mhz with the multiplier and now it's working flawlessly so far. Although I did try that earlier bringing it down to 1600Mhz, I had the timings/voltage off I believe...

Bios Changes:
- I increased the northbridge voltage - one of you guys recommended that. I did actually increase it but not by much before, so I pushed even more juice into it, I think just under 1.200 volts or so. I also added a few extra incremental volts to the "CPU NB VID" (did not touch this before)
- The RAM, especially on Gigabyte motherboards, natively needs a little more juice, I gave it 1.655V. A
- RAM timing, exclusively has to be set to 9-10-9-28 / 2T - even on my 1333Mhz RAM, as soon as I tried "fine tuning" the speeds I would get into some troublesome areas.

There's a couple reasons why I got this RAM. I knew going in there could be issues with the higher speed on an AMD system. But number one, this ram is manufactured to support higher speeds on a stable system. Like I said, I'm getting into liquid cooling, assuming I can get more out of my CPU (it's already at 3.8Ghz on air), the FSB is going up more, and with that, my RAM speed will go up. I wanted something more stable in the 1600Mhz range with room to spare (also I might upgrade to the AMD Bulldozer next year if I can't get more out of the 1045t). Second - it's future proofed! In future builds, I'm sure this RAM will do just fine at it's stated speeds as technology/motherboards/CPUs improve.

Lastly, this RAM DOES support AMD according to G Skill, it's not an intel-exclusive item. It DOES have better support on Intel, but on AMD it will still run. Phenom II chips aren't the best for getting to 1800+ speeds. Eventually I want to upgrade to the FX series so maybe I'll have more luck there. I'll post back here if I have bad news, but it seems like the problems are now a thing of the past, I am going to test it more but I think I'm in the safe-zone now. thumb.gif

So... the issue is that you weren't using the exact timings, or some secondary timings were off. Hey, it happens!

If the bandwidth concerns you, lowering the timings at DDR3-1600 can give you similar gains to the 266Mhz.

Exactly, sure it doesn't 100% match the performance, but tigher timings do help make up the difference overall.
