Intel i9, HyperThreading and Adobe CC Apps...

[DMacX]

Hi all,

I recently built a new rig:

Intel i9 7940X
Aorus Gaming Ultra X299

HyperX Predator 4x8GB Modules

EVERY time LR is run, I get BSOD - I've tried numerous BIOS versions etc etc etc. Literally tried everything, Re-install of Win10, different service pack, different drivers - currently running the most optimal dirvers and every single component driver is up to date. I've overclocked, de-clocked, Manually adjusted voltages for CPU as suggested by some users, reset to optimised defaults, ran MemTest for 24 hours.... you can imagine I've spent weeks.

Sometimes I can use LR for an hour also before BSOD... othertimes I open LR/Adobe and it crashes.

***ONLY SOLUTION SO FAR IS...***

I disabled HT.... and now have no issues.

Does anyone else have BSOD issues when HT is enabled??? I'm now running 14 Cores instead of 28 threads, kinda a pisstake the software does not work with this hardware?

Thanks.

Just so I can follow along ... what is HT?

[DMacX]

HT is Hyper Threading my friend.

In my computer learnings which have nothing to do with Lightroom, Blue Screen of Death is almost always caused by hardware malfunction or driver problems. I would have said this 10 years ago before Lightroom existed, or even if I had never used Lightroom. Lightroom is not the cause of this.

The fact that sometimes it works for an hour and sometimes it crashes instantly, plus turning off hyperthreading might indicate a heat buildup problem, caused by some malfunction in the cooling system.

Adding: there are lots of help forums on the Internet where they have some excellent and very knowledgeable people debugging blue screen of death problems.

Thanks for your reply.

BSOD only happens when running PS/LR. Nothing else. Not even Prime95 for 3 hours.

If I disable HT - I can use Adobe fine - so again - why is it LR/PS does not work with HT technology in intel CPU's - I can play games, watch 4K movies - but as soon as I start importing or working in LR... BSOD. (Unless I disable HT in which case I can work several hours without issues).

You can imaigne, spending x amount on a CPU and getting lesser performance is frustrating - it really is only linked to LR/PP - PS not so much.

This has been discussed many times. LR (and PS) put more stress on the hardware than other software, but in the absence of a hardware malfunction or bad driver, you do not get the BSOD (which is what most people experience, no BSOD).

Also, this does not seem to be the forum where there are experts in diagnosing BSOD. There are other forums that have much better resources for this problem.

The DJ_Paige - I'll upload my minidmp files and get them assessed and then revisit here to update. In the mean time I really refuse to believe a game like COD uses less cpu then my basic image processing in LR - but yes, perhaps it does.

[dj_paige]

But that's what the CPU is telling you, LR requires more horsepower, and your prior belief really doesn't match the reality of the situation.

Importing and exporting lots of photos is often a situation where people find their CPU heats up (and this can cause BSOD if the cooling system malfunctions).

My CPU is 23C and 55C under load. I'm custom watercooled . Heat is not an issue.
