yeah i'd say HD vid editing uses more cpu, but believe me.. high end audio mixing eats up your CPU like you would not believe... most engineers opt for a DSP oboard add on card to
handle the load of the plug-ins so they can keep latency low while tracking.... i'm often on the 50% cpu load levels while just mastering tracks with RTAS plug ins... once full mixing its a lot closer to 75%.. latency while tracking and the need to increase my buffer zones throws up flags all over the place if over-clocking is not stable...

im aware it is not obviously like the torture of a 'proper' 12 hour test... but overclocking over the years i've got all i need to know from intelBurntest... any other gremlins my software is sure
to pick up along the way as I mix.. if you know your way around PRO TOOLS its pretty easy to see when its not stable.... . which is why i'm sticking with 4.5Ghz.. i'm not about to push voltage levels up to 3.65V just to gain that little increase in horsepower... its not worth it..

at the end of the day this machine is absolutely solid... win 7 64bit and pro tools hd 10 are so perfectly set up together there is no such thing as a full on box crash while tracking... you start to see the track meters skip a beat much quicker than that... HD NATIVE is a PCIE 2.0 card that handles my ins and outs... it locks up my system to my converters/ tube pre-amps and outboard interfaces via word clock , i have yet to hear of anybody just LOOSING tracking ability in the middle of a take... things slow down a bit, going by the old days that is... and little glitches are very evident, allowing you to throttle back, if i'm seeing forced throttling just on intelBurnTest i'm pretty damn certain i would see gremlins in PTools,... dunno how high i'd have to go for the box to actually turn itself off as a defense mechanism... heck even FireFox starts complaining when you've got an unstable over-clock... hahahha...

I am at 38x125 alright, but unstable before 1.39V...mad.gif
Temps hover around 78oC for the hottest core, 74oC for the cooler one, under SA SB-E - only run a couple of hours of prime.
Folding was 3 or so degrees less. Left it overnight and just found it doing great.
My 4x 30nm Samsung 4GB are still @ 2000MHz and relaxed timings / 2T till I figure out the CPU.

Left home with Prime95 x64 running @ 4,75ghz, only to return 10 hours later and find that my XFX Pro850 XXX gave in and blew...
I just hope that it did not take anything else with it...mad.gifmad.gifmad.gifmad.gifmad.gifmad.gif

Better to have a problem whilst testing with P95 than to have one in the middle of some video editing work or whatever.

This.
On paper this was the best quality PSU I could get for the price, and Prime95 or not it could not have been stressed pass 40% of its rated capacity.
Also my rig would not have been used just for casual gaming, will often stay @ 100% utilization - mainly multi-hour rendering sessions - you know, those that an 30% O/C would actually reduce by something much more meaningful than the few seconds here and few fps there. I cannot accept that @ 4.75GHz, even @ 1.4V I've introduced a "extreme scenario" for the PSU that forced its cap to blow.

It was just a part failure (bad QC somewhere down the supply line), but having a PC that was up for just 4 days fail like that (and no backup PSU to test if I've lost more than just the XFX) is surely not a happy feeling.

Shorting the green state cable will not fire up the PSU, so I have it packed and ready to be shipped back...probably for a refund, my feet are too cold to get the same one.

Get a Corsair AX850 if you want the same amount of power as your previous PSU. I've owned if for 2 months already and I haven't run into any problems with it. I highly recommend it.

I was trying to save some money - as the corsair/seasonic units were kinda overpriced. Also 80+ gold wasn't something i had to have, so a $120 unit being silver and also re-branded seasonic seamed a good deal. It is not like there are no random failures with any PSU brand - top of the line Corsair/Seasonic and Enermax included.

I am leaning towards a CM Silent Pro right now, as CM has rebate program that makes them more desirable. Trying to stay out of the Corsair/Seasonic trust if I can...saving some money while doing so.

I have been reading this thread for a bit. What is the speed a 3820 does most of the time? Not counting golden chips. I mean if I buy one and a decent mobo and I want to keep HT on. I am putting it under water btw. Will it clock higher than a 3770k or similar? Ivy seems to go to about 4.6.

Just keep in mind that higher efficiency means that you will be able to save money on electricity bill and the initially high price will give you a reduced cost on the long run. Just something to think about when going for a quality PSU.

i think you're missing the point mate... you need to really know how to set up your own box before you start messing around with
the kind of software we're running... and believe me... we know its solid within 1 week of running the kind of mixes and or projects
we have going already...

i've done my research well ahead of time and have been down this hallway several times... prime95 is an unrealistic torture chamber..
and like you said... I will probably never reach those levels with my own software... so its a bit of a moot point to push it to those levels
now isnt it!??? considering i'm already running the top of the line, industry standard HD Audio Editing software...

i mean i see people running the damn thing for a week!! *** for!! and then they pull up their hardcore game with touches maybe 50% of
their machines capabilities on the weekend... i really cannot see what the point of killing your hardware is... these machines, while a great
deal, still are no chump change... i spend my money on great hardware, so it will last me 8 years +///...

at the end of the day... benchmark racing is for noobs... the pro's are out there working... on their more than capable machines...

i dont know many people in their right mind who would go out and purchase a brand new Corvette and just to make sure their fancy supercharger
works properly would take it out to Nurburgring for a week of 24/7 all out racing!!!

its extremely naieve to think you' will ever put it through that kind of
torture while driving to and from work... hell your gearbox will probably give out long before your engine ever actually sees that much use...

dont sell yourself short Dtolios... XFX is a high quality PSU manufacturer.. i did not even know they existed... only knew how much power i would need for my hardware/software needs... my local supplier is the one that pulled it off the shelf for me as I was picking up my new DAW rig, it has been absolutely solid for the past 5 months!! and believe me i've been putting it through the grind...
