Yes, No, and No

Disabling HT in the BIOS will mean you can only run 4 threads (one per core) and will help you push the envelope better. Currently it will not hurt any games performance either. Even BF4.

I got a 4770K because of the presumed increase in highly threaded games coming out. But for now, non of them use it.

You also have to think about voltage though. Just how much voltage is "safe"? If you're ditching prime and the thermal envelope is being maxed out while you play BF4, you're pushing the voltage hardcore (or you have a bad cooling solution). It's hard to measure the effect HT has on temps though.

I think an overclocked Haswell is good enough to last for a very long time. By the time games really need that HT for performance reasons show up, I would've probably changed CPUs. Because for the newer games are just going to be more and more GPU intensive too, especially on my 1440p screen. If you were there for the really really cheap sale on 4770k for Microcenter though, you could've gotten them for not much more than a 4670k.

I'd like Prime to pass with my OC because then at least I have the reassurance that if I ever do need so much hyperthreading power it will at least be stable but I also want my 4.5Ghz so I'm at a cross roads at the moment with what to do

Well it's like I said, for 1.25v I'm getting around 50 degrees for BF4, 60 for Aida and 85 for Prime (until it BSOD's) so I wouldn't say it's pushing it and you're right it's going to be a long long time before games come out that push a CPU as hard as Prime and by then it'll be time for an upgrade anyway.

Still not sure what I want to do with the OC though, kinda feels like cheating saying it's stable for everything but prime

There's a difference between a CPU bottleneck and an application that pushes the CPU into driving insane volts and/or temperatures. I can't predict the future but running Crysis 3 on a 1.3ghz Celeron is not going to cause it to go to 100C. 100% load is 100% load. You'd get similar temps with Crysis 3 on a 1.3ghz Celeron compared to the same CPU running chess (which is 100% load on all cores) or rendering or folding. Prime is something else entirely. But yes, it will be quite a while until you're so CPU limited to the point where spending an extra $100 on HT is more worthwhile than putting it on a GPU, gaming wise.

Yes, it seems that Mantle is benefiting even more GPU heavy systems then people currently recommend. I don't like speculating on the future though. I don't know how many future games will use Mantle and whether their implementation will be good. You're also locked into AMD gpus. And right now AMD gpu prices are way up from bitcoin miners. 

If you want HT stable I don't see why you ought to be Prime stable. You can use HT in whatever programs that normally use HT. I think rendering does? Folding maybe? Chess will do it.

How is it cheating by saying it's stable for everything but prime? This isn't a contest. THis is about finding the right OC for you, not others. The only way to actually cheat is to post fake verification photos or lie about how stable you are. Why are we all so fixated on Prime anyways? What version of prime? Why not Linpack on max memory? How long on Prime? It's based on personal opinion. You're merely limiting your opinions of what stable is based upon what programs software developers happen to decide to make. If somebody made UltraPrime which makes stock unstable, will that be cheating too? We have an application like that, it's called Linpack.

Again, it's about whether you're crashing doing what you like to do on your computer. If you're happy with it, you're happy with it.

2400Mhz Timing: 10-12-12-31-313-2T I also have the uncore at 4.5Ghz. On that, I thought it would be interesting to vary uncore frequency to see what affect that had on it:

4.5Ghz 1157 marks (original run)
4.2Ghz 1152 marks
3.9Ghz 1145 marks

I also varied the memory settings to see it's affect (core/uncore at 4.5Ghz):

2400Mhz 1157 marks (original run)
2133Mhz 1136 marks
1600Mhz 1020 marks

Finally, I pushed my Vcore up (from 1.33 to 1.41) to handle a 4.6Ghz core run (uncore 4.5, RAM 2400hz) and got 1175 marks.

Thanks for the suggestion but at those settings windows fell over trying to boot (blue screen complained about a missing file). I might wonder if running quad channels makes the settings more sensitive?

But I did try a more modest change of going from 2T to 1T (at 4.5/4.5) and it was now at 1172 marks. That's a pretty good boost. I'll have to run some more of my previous stability tests to see if that setting is a keeper.

I observed a large temperature gap with HT on/off in x264 and other threaded loads

assuming a reasonable case temp, my max temp with HT off was ~44c above that (second hottest core) after 2 runs of x264 bench with a speed of 18.4fps

HT on, max temp was 53c above. (so +44c vs +53c - quite the temperature gap) though speed went to 21.07fps.

HT will give you extra performance in some cases, but when it does it'll increase power usage and heat too. By design, it's better scaling than increasing clock speed and voltage - if something scales with it, it's more efficient to use HT than to bruteforce extra mhz. That doesn't mean it gives you extra performance with no added power draw or heat, though.

Does that include BF4 ? smile.gif

I created an OC profile in the Asus BIOS for straight stock settings just for my son when he borrows my PC to play BF4 w/ his friends. It still crashes 4-5 times a night.

I have found RoG Real Bench to be a good barometer ..... tho in addition to above Metro 2033 gave me issues but I think it was the game also. One spot in the game it would freeze....only instance and always in same spot and at another point, all the bad guys were "statues" and AI was unfunctional.

Well BF4 ain't going to crash with 101 or 124 unless your OC is off.
