Might ho x99 myself, haswell is too badly factory gimped to be useful to overclockers.

Solder, Quad Channel, DDR4, 6/8 cores 12/16 threads.. Is very tempting.

Can me see grabbing either the cheaper 5820K and then maybe the 8 core 14nm chip next year after saving, Or go all out now (Sell kidney) and grab 5960X :p

Not really interested in the 5930K as it's just the same as 5820K with more PCI-E lanes and higher stock clock. Obviously you wouldn't buy 5820K and run at stock, and if only using 1 GPU 5820K will be fine.

There won't be anything even close to X99 until more X99 chips next year :D

Skylake (Mainstream) looks like it could be disappointing so far, same 4 cores and focus on lower power, and Broadwell just seems focused on IGPU and lower power consumption. Think X99 is where it's at for next couple of years..

ddr4 comes with skylake tho? I think it will be interesting

True, but it looks like they will still only be 4 cores 8 threads. Targeting low power with improved graphics. I bought an AMD APU for a chip with built in graphics, and it's great, but don't want IGPU on high end CPU tbh, just wasting space that could be used for more CPU imho :D

Think the mainstream stuff will be more of the same, want to make the move to X99, just depends between 5820K / 5960X pricing, and how much I can get for kidney..
 
Just had a play at lower the VCCIN.
Was using 1.9v for VCCIN and 1.25v for cpu at 4.8ghz
Jumped straight in at 1.4v for VCCIN and system was unstable. Kept raising the VCCIN by 0.1v and it was unstable each time untill I got back to 1.9v
Was testing stabiliy using IBT

At least it wont be factory gimped like haswell. A product where the customer has to finish the job. Delid it and then it shows up how mediocre the 4820k is. The z79 platform is a joke compared to x99.

yeah i did the exact same thing, its a 8pack myth lol
 
Looks like I may finally have a stable system again, so will get back to overclocking a bit this weekend.

Least I found a use for my 120gb ssd - my oc drive. So if drive gets corrupted during oc, doesn't really matter.

Will see if can get to my previously stable 4.75. Hope so.

Running mine at 4.6 now. So no faster than my 4770k, just a lot cooler

Was your 4770k delidded or stock? Both 4790k's I've had are a bit cooler in games than the 4770k I had. All at stock, though the dc chips were much hotter if stressed.
 
Same cooler used on all three here, just a change of fans from akasa piranhas to corsair sp's. I'll be having a crack at this chip today after I get the pc rebuilt.
 
Well, played a little bit tonight, with my new 4790k and Z97 board.

Seem to be able to get stable 4.7 at 1.23v (on Intel Burn 10 cycles) with temps topping out at 84c (briefly), however no luck at 4.8 at all so far.

still, not unhappy for an hours work. seems an ok chip. will see what refinement I can do tomorrow with a little tweaking of other voltages.

Those are nice volts for 4.7
 
Settled for 1.24v at 4.7 tonight. totally stable so far at that.

What is really interesting for me is what a difference the chip makes with my 780ti sli over my old 2500k at 4.6. I am seeing a consistent 25% to 30% FPS improvement in Vantage, Fire Strike etc.

I didn't realise the bottleneck was that pronounced!

Looks like a decent oc there, temps arent bad either. The 2500k would have held you back in some multi threaded games, particularly with an sli setup.
 
Amazes me how there can be such a difference, I need 1.70 to do 4.6 and yet someone else can do 4.7 with 1.24, the difference is mind boggling.
