PC Specs Core i7-6800k 32GB G.skill TridentZ RGB CL14(4x8 qual channel) MSI X99 Gaming7 MB RTX 3090 Gaming X Trio Driver Version 460.89 Default BIOS Window10 Enterprise 64bit 1903 When I uses MSI KOMBUSTOR TO "burn"(or test) VRAM, I opens 3x6500MB window and it's fine. VRAM usage is about 20GB. But when I opened another 1700MB window, as the VRAM usage rises to about 21GB, the software and the driver crashes. Error Code in eventmanager as shawn in the attached image https://imgur.com/FEIhJ2T https://imgur.com/nA3qii8 Tried: Reboot the computer Clean installing the drive Set the fan speed of the card to max using the msi afterburner The card could reach an VRAM usage of 23.7GB with using on the OCCT(uses 19.5GB VRAM), and GPU Memtest v1.2(uses 3454MiB VRAM) together, no errors occurs Have not tried: Use DDU to Uninstall and then install graphics drive Reinsatll the system Really appreciate if someone could help!
Use different app or software for VRAM testing, something like Blender or LuxMark if you are use OpenCL, don't use Kombustor for that Hope this helps Thanks, Jura
Well, I did open three 6500 MB windows one by one. With an interval of several seconds, it would work fine(as long as a use a small testing window resolution, if I use for example 3840x2160 for each testing window, the card would stop working when I opens the third window, these windows are all identical and consumes 6500MB of vram regardless of the resolution) But when I opens one more 1700MB window, the card would stop working at about 21000MB VRAM usage. The maximum ram speed I could slow down is -500mhz in AB(equivalent frequency) Doesn't seem to have help Still, thanks
Well, just want to test if my card is fully functional The card could reach an VRAM usage of 23.7GB with using on the OCCT(uses 19.5GB VRAM), and GPU Memtest v1.2(uses 3454MiB VRAM) together, no errors occurs
I tried LuxMark but is uses little VRAM, I turned every VRAM consuming options on but still it uses only a few gigs of VRAM. Could you help? Thanks
Same card here. I get what you're trying to test, but not convinced you're using the right tool for it. Got any real OpenCL application to run from?
I’m a gamer and not really know much about these. Could you recommend a few programs or benchmarks to test that would use all of the VRAM and test to see if they function properly? That would be a lot of help Thanks.
If you want to push game testing, maybe consider running games at 8K. with DSR/DLSS Ray Tracing. Here CoD: Modern Warfare Campaign is running at 8K using DSR, with Ray Tracing. It's using 18.5Gb VRAM. Same with Horizon Zero Dawn at 8K
the funniest thread how about no DLSS. anyway only 18,5 GB; he needs 24 GB easily the funniest thread
Game at 8K + Chrome opened on Amazon prime with a bunch of tab with The Expanse episodes then ! (+another game opened at 4K?) Anyway, a game at 8K sounds more relevant than a couple instances of the synthetic MSI VRAM bench. (never tested it, don't intend to test it btw)
You can try Blender and use subdivision and tessellation etc, create custom scene etc My scenes usually takes up to 10GB easily and I'm already limited by VRAM, rendering with single RTX 3090 is okay but rendering with RTX 3090 and 2*RTX 2080Ti's then is properly quick I optimise my scenes, reducing polys, textures or removing some parts which are not visible I recommend downloading Blender and find some larger scenes and test there VRAM usage Or you can try GPU RAM drive and install game on VRAM Hope this helps Thanks, Jura
