Okay thanks, will see if I can get hold of some dry ice to have a go.

Just trying to figure why it won't go as tight as it should. Frequencies can definitely be pushed more than my previous ocz though.

Only testing with 1M at the moment but it's stable @ 1800mhz with 9-9-9-24

So you will be beating my AMD score then :)

The GEIL's which i think are PSC responded well to voltage increases.
Lower the timings the more volts they needed.
I also found that i had to increase the CPU-NB volts a lot also to keep things stable as the timings got lower.

Possibly it depends what I can pull of with hitting the sweet spot with everything. I can hit just over 2900mhz on the Nb. One stick of the mushkin is a lot better than the other. One hits a wall at around 1816mhz but the other is fine for 1848mhz so far.

I just need to work out the optimum for it all while keeping it under 4040mhz clock speed then I can tighten up the timings


Edit: can't even get into windows with both sticks @ 1600mhz 9-9-9-24 1TI at the moment

Edit edit: into windows seems a bit flaky if I push more than 1.75v through the ram though.

Edit edit edit: can't push the ram frequency and the cpu-nb frequency with two sticks of ram. Currently running 4033mhz cpu 2834mhz nb and 1744mhz in the ram. It boots and stable enough to run 2M so far. Will try 4M followed by 32m to get a baseline to work from then start pushing the timings

I ended up with my CPU-NB up around 1.475V for running at 2882mhz and the ram at 1658mhz 7-8-7-18-17-2T. But I was pushing 2V through the ram to get that stable as 1.95V wasn't enough. From what i can find, my hyperX sticks use elpida BFSE IC's. My corsair dominator modules wouldn't tighten timings from CL9 no matter what voltage. One thing you could try is using cputweaker or memtweakit to adjust the timings on the fly in windows.

8 pack could well be right though, and your cpu may just have a poor imc. I'm still trying to find some better ram for mine.
 
BBSE that is mate. I have some hyperX too good for Cl6 2600. I think I will take a pic of my RAM collection this weekend just to show. Its a serious amount of sticks.
 
I tried cpu tweaker and the changes don't seem apply, cpuz still reports the timings as set in the bios.

Mine doesn't boot with 1.85v or more on the dimms.

I'll see how tight the timings will go as things are then I'll try dropping the memory frequency a touch and pushing the cpu-nb frequency a little higher as I managed 2920mhz or something close on the OCZ ram.

1744mhz on the ram isn't stable failed at loop 14

:eek: Is that the 1600C9 stuff? (if that's the case, my question about ram in the ask 8 pack section might be unnecessary) I couldn't get anywhere close to that. I think my phenom IMC might well be the weak link too then. My system wouldn't post with the frequency much above 1700 no matter how relaxed the timings were. I'm assuming you didn't need to jack the voltage up as high as me?

Hence why i'm a little uneasy about the idea of buying new ram that is "supposed" to clock higher and have much tighter timings. I'd hate to drop £40-60 for it to make almost zero difference.

I'm now thinking a Thuban chip is the next answer. I can't push the ram frequency with the cpu-nb anywhere near 2.8ghz let alone the 2.9 I had it at yesterday.
 
Possibly the CPU yeah. Can always be the cause. Some Haswell, Ivy etc will not go as tight with certain settings than others.
 
What I don't understand is how with the ocz it fine running at 2916mhz cpu-nb with 1619mhz ram yet it can't even get the initial value that high with this mushkin.
 
Try dropping Trfc for DIMM1 and Trfc for DIMM2 down from 90ns to 110ns or 160ns and see if that helps. Most of your sub timings seem quite low, tWRRD in particular.
 
That may well be the problem then. I have all of the options available on my 790FX board but i'll admit to not tweaking them much, maybe i could have gotten more out of my system by relaxing them. Having Trfc lower than 160ns with the kingston modules stopped my system from posting. All my sub timings were set at their stability limits which is how i run my system by default 24/7.
 
I think you're right. My sub timings are totally different if it set my timings to auto in the bios then look in cpu tweaker.
Edit: I flashed a later bios earlier and before that it was running a full 4M loop at 1744mhz on the ram. Won't even do 1M at 1600mhz with the same timings now. Going back to f5

I've concluded this ram is * *****

It's suppose to be 6-8-6-24 1T at 1600mhz it won't even do Superpi 32M @ 9-9-9-30 2T 1600mhz

Please fully star out swearing
