Must be nice having a decent watercooling system! My D-14 at 4.5 GHz gets up to 90 on 1 core, but mostly high 70's. Still don't understand the correct temps for this chip. I run 1.116V at 4.2GHz, max temp is 60c on core 2. rest are at 56-58c. I'd like to get to 4.5 but not sure about my temps.

Incase you didn't notice - he's not running prime with AVX!

Neither was the guy I was comparing to :p It's equally fine on the AVX version at 4.5 @ 1.2v, although 4.6 @ 1.235v got rounding errors it didn't on the older Prime. It managed a good few rounds though so I'd guess it'd get away with 1.25 or so.

The thermal paste seems to have set now, if anything the temps are lower than before, 15 minutes in and 65 degrees max.
 
BrainB what volts you pushing though at 4.5? You maybe able to lower you CPU PLL to help shave a few degrees at 4.5 I was able to drop my CPU PLL down to 1.450 a shaved 3 degrees off for free :-)
 
Yeah bought the 570 and have it here with me now, ill probs sell the 460 to bro for £75 so its what £55 total it really cost me? Not too bad i reckon overall for a gfx card upgrade which should last longer than the 460 plus the 20fps extra it gives in a lot of games at 1080p will be nice too (according to benchmarks and reviews).

If i dont get on with the 570 for whatever reason i think i could make my money back easily enough i mean if i payed £130 for one of the nicer 570s (phantoms i hear are hard to get hold of) then im sure someone else would pay that for it.
 
Lol no way would i pay £200 for a card. My max ever for a gfx card would be 120-130 and would be 2nd hand to make sure i got a strong card at a price i could get. Plus selling whatever card i have at the time before they go too cheap is another thing i do so it pays for half the new card i get. Least i try to.
 
Yeah I paid 330 for my card, but sold the games off that came with it for about 35 quid and made about 120 quid on my cards at the time, they'd of dropped massively in price by now so only paid quite a little for a decent upgrade.

It compared to stock speeds of the intel cpu's.

Would still get demolished when overclocked it seems.

depends how it overclocks tbh though and its only had certain benchmarks done.

Need to wait for something a bit better until we really see what its like.

Some gaming benchies would be nice.

Hopefull can get a 25% OC from it up to 5ghz.
 
The cores are still barely any faster, all they have really done is bumped up multithreaded performance by increasing the base clock.

So in summary, it looks like Piledriver is going to be 15% faster in the few areas where Bulldozer is strong (encoding etc) and only 4% faster in the majority of applications where Bulldozer is slow.

IMO its only hope now is being able to easily hit 5ghz on air, which I would say is doubtful given that the turbo frequency has hardly increased at all.

P.S. most of those graphs are multithreaded benchmarks and so are best case scenarios for Piledriver.

Making the move to ib this weekend, currently using an i7 920 @4.2ghz, Asus p6t deluxe v2 and 12gb of kingston hyperx. Going to the following.

3570k
Asus P8 Z77 v pro
8gb Corsair vengeance lp

Cooling will be An Alpenfohn k2.
 
Got a stable 4.6ghz OC on 3770k

VCORE 1.280 (or 1.275 cant remeber, im at work :()
LLC on High 50%
Memory 2000mhz (never stable on my XMP profile 2133mhz for some reason)

Does full water cooling make any difference with Ivy? I'm running the same temps as above on 1.280vcore 65-70c Antec 620.

No not really, mines under water and my temps are as high as every one else, I think it would help to delid but I can't afford another if I break it.
 
Just starting with OCing my i5 3570k manually.
When using the auto OC to 4.4ghz via the Asus tool it puts vCore at 1.325, which seems fairly high.

Using ROG connect to see if I can get this down. I had it really low and got errors in Prime95 and then some boot issues.

I did notice that the manual 1.325v set my the asus tool drops when running prime to 1.266v..... I have no idea why though. When running Super Pi it stays around the 1.325v mark.

EDIT.
From reading up on the drop in volts under load, then this is known as VDroop. I have a Asus V Gene board, which was to Medium LLC (25%), upping this to High LLC (50%) makes to between 1.29v and 1.3v, so 0.03 roughly.

EDIT2.
Setting LLC to Very High (75%) means the voltage stays fairly solid under load. Should hopefully now be able to reduce vcore a bit.

Had to get a few more things before i move to my new setup. Bro is having my old system more or less just minus my hx620 psu, and hard drives now so im waiting on a new case and a psu for his and a ssd for his and a dvdrw for mine as ill just leave the one i had in his.

Most stuff should come monday i.e the case and the psu, the ssd i duno depends when ocuk post it which probs be monday and wont arrive til wed probably and the dvdrw around thursday due to free slow delivery from somewhere. Probs have it built all up by end of next weekend tho.

Man im itching to see what the new get up is gona be like :) I just hope i backed everything i think id need up from ssd on to a hdd.
