Post Re: i7 3770K overclocking
i've been searching and googling around and can't find anything. i think if it's anything, it's probably a really old version.

can you run Fire Strike with physics handled by the cpu? that's how I ended up running prime on my SB-E and finding that prime fails on it at stock. so far it's had no other impact on me though, so i haven't bothered to replace it yet

just saying, might be a way to test it with something else

what's fire strike

edit: never mind, i just looked it up. been out of 3dmark scene for so long. just don't really care for it.

so i just run the fire strike scene? do i need to do anything special like enable phsyx or anything. how many times should i run it.

and do you mean you had Prime95 running at the same time as FireStrike runs? or what did you mean.

Post Re: i7 3770K overclocking
ok. here it is.

i got the new chip. it's cooler, faster and requires a lot less voltage to run. the last chip ran 1.2v at stock speed, as this one runs 1.1v at stock. due to this, i was able to clock it up to 4.8ghz for a stable 24/7 run.

now here's the deal. i ran the new chip at stock speed and guess what, it failed prime95 V27.9 within an hour. so i was thinking, there's no way!. so i decided to turn turbo off, and without turbo, the chip runs at 3.5ghz 1.02v, as oppose to 3.7ghz 1.1v. and fired up prime again, and this time one of the workers failed within the first 8 mins. so i was baffled.

so 3.7ghz @ 1.1v (with turbo) - Auto vcore, auto everything
3.5ghz @ 1.02 v (without turbo) - auto vcore, auto everything.

then it got me thinking... could it be that intel's stock voltage is too conservative. could it be that the SVID is too conservative. so just for testing purpose, without turbo, i bumped up the voltage to 1.1v just to see if the stock voltage really was too lean. and it turned out Prime95 V27.9 ran 5 hours straight without any workers failing.

so with this knowledge i was able to scale up to 4.8ghz @1.37v.

one question still remain, why is Intel's SVID so lean. do they just not expect people to run extreme burnouts? do they assume people won't be doing hardcore calculations? as the only program in the market today that'll utilize AVX extension to stress the CPU are V27.9 of Prime95, and newest version of IBT. so these are the only two stress programs that really maxes out the procs to the highest temp, and highest FPU stress. do intel just assume that people won't be using AVX extension calculation for crunch? i mean at stock speed? com'on.....

so at the end of the day, i learned that Intel's new Ivy is very lean on stock voltage, depending on what you do. for average joe, one might never run into a problem. but for advanced users, people who do a lot of intense rendering, mathamatical calculation, especially ones that utilize AVX extension, you might even run into issues at stock speed unless you bump up the voltage.

the silver lining of the day, i got a MUCH better chip. one that'll run 4.8ghz daily and load temp remaining at high 60's low 70's.

So it fails on Intel's tool too?

inte's IBT for some reason isn't as stressful as V27.9 of Prime95. although the temp is slightly higher in comparison. what i could pass for IBT sometimes crashes with Prime95 V27.9.

Well as long as all your games/apps are stable, that's what I consider "good enough". It's very rare that your CPU would ever undergo that sort of load.

well. call me old fashion. i'd like to have the peace of mind. plus if you encode a lot of X264, the latest X264 utilizes AVX.

Been a long time since we've had a good old-fashioned "inside baseball" tech talk in here. It's nice.

:D

anyway we can implement some kind of Like button or Reputation system in here. sometimes when you agree with someone, it's just too much work to type "i agree". :lol:

It's on the list. I think first comes an upgrade to vBulletin.

Not my fault you don't want to pony up the money and buy real hardware ;)

That being said, stlouis likely has me beat with his SLI'd GTX780s.

Since the last time i posted a video of my rig was back in 2008 when i first built the case. i thought now might be a good time to update it with the new parts. :mrgreen:

I'm not sure i have you beat. I posted screens around here somewhere didn't I?

I'm thinking in a couple months I may buy one of the new IB-E's to replace my SB-E since it fails prime95 and firestrike with physx running on CPU.

Either way, seems we have ourselves a good little hardware race here going. I'm gonna have to get a bigger psu and do some overclocking ;)
