I got my 7750BE and set it to 3GHz. I want to test stability with OCCT Linpack but it only loads one core. The regular OCCT test loads both just fine. How can I make Linpack load both cores?

Did you try reinstalling OCCT when you put in the different processor?

OCCT doesnt install iirc, at least the download i have doesnt :ohwell:

Does OCCT detect all cores in its temp monitor? You checked they all exist in Task Manager?

Finally you running the latest version? 3.1.0?

Yep, I redownloaded the zip file (reinstalled it). I see both graphs in task manager. WCG runs two work units at a time. Running latest version of OCCT

I ran the large data set on high priority while I was away for 6 hours. All good, and undervolted too... the chip has a VID of 1.325v, I ran it at 1.3 and it's stable for 6 hours for the regular OCCT test which is pretty good. I'll have to give linx a try.

Linx didn't load both cores either, even though I made sure it was set to 2 threads. What if I just ran 2 instances of linx?

I think I'm going to end up reformatting. God I hate doing that... this is just like when I got that quad core, temp sensors wern't reading properly... ugh.

ok... even after I reformatted it STILL only loads one core. this fucking sucks hard... I have to go through and reconfigure everything, and all for nothing

wait and leave it for a bit. mine dropped to one core occasionally as it filled up my ram, i assume its alternating between tests.

Yep, after about a minute it loaded the other core. So I reformatted for nothing... leet. D:

I want to bend a cast iron skillet with my bare hands

At least I can test out my overclocked undervolted cpu properly... but what about temps? Both coretemp and hwinfo32 don't show my core temps, they show cpu socket temp.

there is nothing more awesome than a CPU that gives you a 25%+ clock increase, at or below stock voltage :D (except one that gives 50%!)

This was an 11% increace. I see people taking them to 3.2 and 3.3 but I'll just leave it at 3, espically since it appears to be stable at 1.3v where stock is 1.325v. That and my motherboard isn't very strong... heh

naw... it was single core, and single core isn't leet
my semprons that i owned (4 of em, when i had my lan cafe) all went from 1.6GHz to 2.4GHz, stock volts and stock cooling - loved those things :D
