5930K OC stock speed and OC experiences

[escrow4]

I originally shelved my X99 upgrade plans but now with all these fat old AAA games its back on (buying in a few hours). Looking at a 5930K and X99-A. Question, how is this at stock settings? I've never been interested in super high OC's (or overclocking at all TBH), and at stock all six cores will run @ 3.6GHz. What have you gotten your K's up to? Will there really be a large difference between 3.6GHz and 4.2Ghz or so? I have a Noctua NH U14-S.

EDIT: Out of stock, adjusting to 5930K and Asrock X99 Extreme 4.

Bought and installed. Activated MCE for a solid 3.7GHz across all cores, everything on Auto for now. Auto voltage is max 1.1v or just over, usually dipping way less under 1v. Me like. A LOT.

So how much faster is it?

I have mine stable at 4.6 ghz vcore around 1.36v vinput is 1.8-1.9 . I know it can go faster just havent tried yet.

Seems like you might have gotten a pretty good chip. What are your temps at 3.7? I would think you could go 4.0 or so easy.

3.7GHz is less than 50 celsius. 4.0GHz freezes @ 1.2v, 4.2GHz freezes @ 1.24v or so, looks like overclocking is rather a dud. Not shoving 1.3v through for 4.2Ghz ish. I only play single player so another 500MHz isn't an issue. Not yet anyway.

what wattage is your psu powering your system escrow?

Just an idle thought, having come across this thread before coffee and breakfast.

Consider. With any of these chips, you get either six cores or eight, depending on whether it's the 5960X, the 5930K, or the 5820K. That's either six or eight physical cores.

Who is overclocking these chips with Hyper-threading enabled? Who is overclocking with HT disabled? I assume that OC in raw Mhz will be greater with HT disabled.

It's never been very clear from posts about OC'ing these chips as to what folks are actually doing with them.

I don't consider disabling HT really a valid overclock, that's like the people who disable cores and run single channel memory at ridiculously low speed to get a high cpu-z validation score. I've not tried to disable HT on my 5960X or X5670, it didn't help one bit on my 3930k. It did gain quite a bit of clockspeed on my W3520, right at 200MHz, temps dropped too.

I guess the Sandy Bridge E experience would prove it, as you say. I'm still convinced that disabling HT would get me an extra 100Mhz on my SB-K processors, though. I just don't see the need . . . for such a small slice of extra speed . . .

 

[YBS1]

Probably going to depend on the individual chip, like I said it didn't help my 3930k but I was pretty maxed out to begin with, got a pretty golden chip. It does drop temps so that alone will give some people some more headroom.

1000w FSP Aurum Gold which though slightly old got a decent review at [H]. I don't really overclock anymore anyway. The option is there if I want to go nuclear but when 6 Haswell cores @ 3.7GHz become slow and can't hit 60FPS, a new hexa will be out.

Well you just did overclock. Stock is 3.6 GHz on 6-core loads in the 5930k.

I understand what you are saying, but in the real world, it's quite likely that with 8 full cores at his disposal, escrow might be better off with HT off, regardless of the overclock.

 

[YBS1]

Oh, I agree. On something you know can't use more than eight threads, with it disabled you at least know the work is going to be assigned to a physical core.
Edit - He has six, same idea though.

 

[crashtech]

My bad, 6 cores, yes.

 

[xanderkeys]

I'm not sure if HT is disabled .I wanna say it is but i could be wrong my 3770k didn't like it while overc locked. I dont know much on Haswell
It's definitely been easier to oc my 5930k . I'll update the post I'm out of town so i cant look if its on or off.

Casually, I'd bet on it like I might bet on the horses: either temperatures will subside a tad, or a higher clock can be achieved -- if only at a margin.

Actually I was thinking of partially loaded scenarios where the scheduler might pick an HT resource instead of an adjacent underutilized core; it's highly load dependent whether HT confers a benefit or actually induces a slight regression. I haven't had a hexacore to play with, but it seems that the partially loaded scenario would be even more common with them than it is with the HT quads, and regressions have been seen with them quite commonly.

I only wish I could switch easily between HT "Enabled" and HT "Disabled." Anyone, of course, will ask "How is that a problem?"

It's a problem with my Media Center configurations. It is as though the extant WMC setup suddenly sees "a new processor" when I disable HT.

So if I want to keep using WMC, I either have to choose HT or no HT and re-run the WMC configuration process. Very . . . freakin' . . . incon-freakin'-venient. . . .

 

[xanderkeys]

HT is enabled while stable at 4.6 and even at times have seen it jump to 5.4 ghz but it throttles down in a split second . No problems so far .

So you are forced to re-run the config? I don't think it would make any difference to WMC either way with the amount of CPU power you have available.

Of course it's not a problem for WMC. WMC is such a low-level process that I can run my TV as a second monitor while gaming on the desktop monitor, and the CPU usage barely clips 5% with WMC alone -- if that.

The problem is the HDCP factor. So, yeah, I need to re-run digital cable advisor or "whatever" if I change from HT enabled to disabled or vice-versa.

Just such a pain, really. Freakin' . .. Jack Valenti, Media Nazis and HDCP. I looked into the Windows 10 upgrade thing, to discover "no WMC." Then downloaded KODI to give it a try -- NO . . . FREAKIN' . . . PREMIUM CHANNELS!

I wanna kill! Blood, guts 'n' veins in ma teeth!
