I'm getting stuttering in games with a Bloomfield i7, some a lot, BF3 for example is an unplayable mess unless i turn HT off. but even then its still not perfect.

Is this still the same with Ivy Bridge?
 
I've seen HT blamed for stutter a fair bit but over dozens of setups I've never experienced it or been able to reproduce it myself.

Theres a lot of tweaks for BF3 that can dramatically change how smooth the game is tho i.e. the render ahead setting.
 
Turning HT off fixed it ^^^ 90% anyway....

it shouldn't stutter at all

is it oc or stock? and what speed ram are you running?

Stock (2.8Ghz) its a warm CPU on stock cooling for now.
Set 1333Mhz RAM, default is 1066, capable of 1600 but cannot get it to boot at that.

Performance is no better than my trusty old Phenom II x6 which also loved to be played with and adjusted, nor was there ever any problem doing that.... unlike this.

Me no like it :(

A real poke in the eye, pun intended :eek:

ram speed wont help,1600mhz+ helps a lot on x58 plus stock cpu speed,even a mild 3.6ghz oc would help more

idk what dram voltage your memory is rated at but set it to rated voltage either 1.5v or 1.65v and set the qpi/vtt or dram/vtt (cpu imc)to 1.315v then it should boot

I played countless hours on crysis with my i7 920 and no stuttering at all,and that's a multithreaded game aswell

you need to get a good cooler and oc it,and maybe some 1800mhz ram,but 1600mhz will be fine,1333mhz is too slow imo

Thanks, i will have another go with it tomorrow, its a bit late in the morning now :)
 
yh it is,its more cpu imc voltage that's probably needed for your memory

setting twice what your memory multi is and adding one to it will help for uncore frequency

so 10x ram multi would be 21x uncore (2x+1) and so on
 
If your rendering on an AMD card then use radeonpro or similiar and try settings Flip Queue size to 2 (or could try settings like 0 and 4 but higher values induce input lag). If your using nVidia then change the maximum pre-rendered frames to 1 or 2.

If your using Vsync then try the method of capping framerate to a slightly lower value than the locked Hz rate thats used to reduce input lag IIRC its 59 for 60Hz - it can also reduce stutter on some setups.

Had the same issue on my i7 920. Didn't do it on any other game. However, about 6 months after launch they patched it I thought. I turned HT on and no more stuttering.

Are you sure your up to date on everything?
 
My old i7 920 ate BF3 for breakfast. A f..k was not even given. Though HT didnt help my fps one bit(nor did it make it worse). I would change that stock cooler to something useable.. like a cooler master 212 evo.. its cheap and very good for the money you pay. Also what volts are flowing through it atm? and what mobo is it sitting on. I had all sorts of trouble on a gigabyte x58 ud4p, but the second it got switched for a sabertooth x58 the kitten started to purr.
 
BF3 runs smooth on my 920 with HT on, as others have already pointed out they fixed that quite a while ago. There's probably something else causing it that you haven't found yet.

HT stuttering with i7's was fixed a hell of a long time ago on bf3.

A dodgy RAM module, i spent a lot of time this morning running Memtest as it failed first time round at 44%, identified the faulty module, removed it and turned HT back on, runs fine now :)

Excellent news.

I miss my i7 920, but I only got rid of it the other weekend.
