I've got 4 sticks of 16Gb memory, and it's showing up as quad channel at the default speeds.
I've tried switching on the XMP profile (and it recognizes the ram and looks like it's setting stuff), but it just reboots 2 or 3 times before reverting to the default values again.
I assume I need to adjust some other values in the bios. What should I be looking for?
It's an AsRock Fatal1ty. Memory is GSkill Trident-Z F4-3600C17D-32GTZR (so 2 packs of 2 x 16Gb)
I've managed to get the memory going at 3466 so far without setting any specific voltages. 3600 fails.
Thats pretty good for zen architecture when using 4 double sided sticks - Well Done
Thanks. I know someone with the same memory and CPU but an AsRock Taichi board that's allegedly got it going at 3600. I've asked for details, but it's the weekend, so no doubt he's busy somewhere. I suspect I should be able to use similar settings.
There's so many values that can be changed, I'm not sure what to play with as yet. I also haven't read enough to work out what are reasonable values for some of the fields.
Well, I discovered that the person I thought had it going at 3600, in fact, did not. So, I'll be pioneering. I've got a few things to fix up first before I progress further as I'm doing all my testing using Linux. I've got a special image processing tool I use that has a benchmark test in it. That's run quite sweetly with some excellent results.
I though 3600 for a stable day to day speed was "very good" so that makes a bit more sense to me now
Changed the timings from 17-19-19-19-39 to 16-18-18-18-38, ram volts to 1.37v, ran memtest and that passed successfully @3466.
4x16 gig sticks anything stable over 3200 is very good but stable is a bit of a perspective type term to some its 1000 percent hci memtest on some its just superpi 32 etc so be sure to load it up to test it.
have a hunt around for stilts stuff on overclock.net he has some very nice presets hes testred not sure about 16 gig sticks though
Yeah, stable is perspective - I am going for at least "short-term" stable right now.
I've gone through a thread relating to the board on overclock.net - haven't found much related to 16Gb sticks yet.
Overall, I think if I get it more longer term stable at 3466 for the memory, that will be fine.
I did a few tests between 3466 and 3333 and 3200 on my flarex and really the differences were not huge I settled on 3333 because it was lower voltage better timings and just did well.
3466 hasn't survived over a 3 hours, so I'm going to drop back to 3333 and try to work on that further. I'd like to get lower voltage and timings as well, as I think (from my limited testing) that it had better impact than the increased mhz. What sort of voltages did you get?
on the ram? I am running 1.38 I can get away with 1.35 but decided to nudge it a little. cpu is 1.331 llc4 or 3 can't remember but full laod drops to 1.306 that is prime stable as well
Looks like 3333 for the memory is working for me. Left it at 1.35. I've got it going at 16-18-18-18-38. I set the cpu to 1.225 and level 3 (the other level setting is on 5). Have run various perf tests, will run some more, but it's looking pretty good.
I've also set the CPU to 3.9Ghz with no change to the voltage for it. Haven't worked out how far I can push that yet.
Oh yeah, in another face-palm moment, I realised I wasn't on the latest bios, so I updated to that. The tctl (or whatever it's called) changed upwards, but it was consistent in the bios and as reported on the led (they were out of whack before), and the fan profiles seemed to start working better too. I believe this value reported includes the offset in it. I need to do some longer period testing where I control the ambient fully (i.e. in A/C only and no stupidly high humidity). I think I'm idling a few degrees above ambient (maybe +7C?). Not sure if that's ok or not.
Hit 4.0Ghz but haven't cracked further than that. Got the ram at 16-17-17-17-36 (still at 3333Mhz). No other changes. I think I'll stop there for now. Temps are ok-ish - when the ambient was quite warm (high 20s, maybe low 30s and high humidity), under full load, I hit mid 90s temps (that includes the offset). The system seemed ok with that and wasn't throttling the CPU. Now that it's cooler and less humid, the highest temps are dropping right off.
Now I've got to find time to get my data sorted and do some heavy processing on it - should be great, I think.
