0.11 is much, much, much better here... thanks :)

on 0.10p1, one LL TF test took about ~8 hours, with 0.11 it takes about ~4.5 hours

Thanks :smile:

what hw are you running? I have not seen an almost-doubling in my tests ... Did you change anything else?

Anyway, it's nice to hear it's working well.

P.S.: Using 64k binary

on chip graphics
 
I am using an i7-3960x with a Radeon HD 7970. mfakto compiles and passes both the self test and the two suggested test worktodo values. When I give it something that takes more that a couple of minutes, I lose my screen (all monitor timeouts are disabled). Sometimes it gives me a messed up screen first. I can only get it back by doing a power on reset. Is there a way to force the system (Win7) to use the onchip graphics and leave the video card for opencl work?

Thanks,

David

Ummm... Connect the monitor to the IGP output?

This simply shouldn't happen. What do you mean by 'all monitor timeouts are disbaled'. I sounds to me like there are either driver issues, or you have a faulty video card and the stress simply shows the bad hardware.

The i7-3960x does not have on-chip graphics, so that's difficult. Do you have another PCIe slot that you could put a cheap low-end Radeon in?

on-chip graphics
 
fivemack is on to something. It looks like the first thing I need to do to force the use of on-chip graphics is use a processor that has it. By "all monitor timeouts disabled", I meant under power settings, among other places, I chose to never turn off the display. I'll give new drivers (if they have come out in the last month) a try and a low-end buddy card (probably my best shot). I sure hope my card is not bad. I'll need to find a non-mfakto way to test it.

Many thanks,

David

God, I hate the designations on the SB-E... I saw the '3' and without thinking assumed it was Ivy Bridge. Good catch fivemack. Damn you and your stupid names, Intel.

+1

Me too. Those are damned confusing.

i7-39xx - hex core +HT LGA2011
i7-38xx - quad core +HT LGA2011
i7-37xx - quad core +HT LGA1155
i7-35xx - quad core no HT LGA1155

LGA2011 - no inbuilt GPU
LGA1155 - on die GPU

It does have some sense to it.
