Corsair Obsidian 750D Windowed ATX case

Bits from existing PC:

Sapphire R9 295x2
Sapphire Reference 290x
Samsung 512GB 850 Pro
Samsung 256GB 840 Evo
3TB Hard Drive

Waiting for:
Swiftech H240X AIO Watercooler


Hoping for 4.5 Ghz overclock but can't do anything with it at the moment :(

I've finally got myself stable on a nice 5960X 4.3Ghz Core overclock, 4.3Ghz uncore overclock with 3200Mhz memory tuned in at CL12. Happy days. :)

Just don't ask how much voltage I'm using LOL.

3200C12 isn't really possible with 100% stability, least not on ambient with Hynix. If you're stable when loaded up properly with 16 threads then you're probably using too much voltage. If it's over 1.45v it's too much

I assume - you may correct me, that 1.35v and below is best for 24x7? According to temps also of course>

It's not so much the temps, 1.4v shouldn't get them much over 30c if you've good airflow. It's both the current and voltage that will do the damage. Nobody, even seasoned beta testers know at-what voltage degradation will occur. But 1.45 and above is serious voltage for these.

The main point regardless was that I doubt Matt has C12 fully stable. If he is using the timings he posted recently, the chipset will be correcting a few of them. To run that latency at 3200 and have the system fully stable is unlikely to say the least. This is why you should test with HCI mem test and load up all threads.
 
I was using 12-15-15-30-1 and tight seconds and thirds. It was stable, then it became unstable so now I've relaxed it to CL13 and all seems good. Lowered the cores to 42 for 24.7 as well just to keep temps lower. Was using about 1.39v for 4.3, so yeah my chips a stinker. 42 needs just under 1.3v.
 
;)

C13 T1 is still a bit fantastical for daily use bud. Post up timings, will see if there is anything that can be changed. You should at least stress the memory on 12 instances for 200-400% or else you're stabbing in the dark

I'll give that a go, cheers.

One thing I've noticed and I'm guessing this is a sign that things are not 100% stable is sometimes when i restart the pc it turns itself on and off again, then continues as if nothing happened. The annoying thing is, it passes RealBench just fine giving off the impression it's stable. Will have to try that thing you recommend.

EDIT

What was the name of it?

Hey Matt,

You will probably find that the double boot issue is because of memory training settings in the bios - have a look and set it to maybe not train memory every boot.

The turning off and on is because the IVR is crapping itself. Normally cache instability or too little input / vcore

Or if it's only doing it pre-post it'll be memory training. If it's doing it continually at this point it's struggling to retrain the memory.

You can turn mem training off when the machine is stable, you may find you have to do this with how you are running the ram, as there will no doubt be drift in training. Be sure to re-test the memory after disabling training. This is because when it retrains one final time on reboot there may be drift that has caused instantly. I would imagine you will end up raising latency furter before you're fully stable.

For HCI mem test pro run 16 instances (open 16 times) for one per thread. Load 85% memory. 786 per instance. Test for 400-600%. If you cannot pass this long the RAM isn't stable.

I took the plunge and changed from my i7 2600k yesterday.

Thinking something must have been wrong with my old setup because the new one is startlingly faster in games.

I used the 980's in SLI with the old Z77 sabertooth and they performed okay in games really but benchmarked really low.

I've just used the Asus software to overclock and its running really well at 4.4 with my memory clocking 3100 MHz.

Temperature of my 5930 doesn't exceed 40 degrees which makes me wonder if it's capable of being pushed much further?

Really glad I upgraded, Was worried that I might have spent a fortune and not seen the benefit.

You can push for more but voltage will be your problem what are you running your cache at.

I'm a bit of a noob when it comes to overclocking and have only used the 5 step optimisation Asus programme so not sure if that would impact on cache settings?

Changed the multiplier so now running at 4.7 ghz and seems really stable, well at least it hasn't crashed or caught fire after a couple of hours of playing DA Inquisition :)

Will probably leave it as it is not and move to overclocking my 980s.

Never realised how satisfying overclocking can be, ran the shadows of Mordor benchmark about 100 times lol
