I haven't loaded that yet. Probably for the best. memtestCL is showing my card failing the random blocks portion of it's test. I can only test 2048 of the video memory with the test as it fails to allocate memory if I choose more than that, but at least I have a 3rd point of reference to say I have bad video memory. mad.gif (it fails on stock settings) Anyone know if this test is reliable on Ellesmere?

Can help you? - I need to download MemtestCL and check the mem video card?

If you'd like to. I downloaded it from here: http://www.majorgeeks.com/files/details/memtestcl.html

from a command prompt I ran >memtestcl 2048 10

2048 being the size of the memory allocated 10 is the number of loops. I fail random block every loop. I used cmd with administrative privileges but I don't think I needed them.

Yes have memory errors in "random blocks" so probably its not real because in gaming with HWiNFO don't have any of them - and the second time I run the test get a black screen and a blue screen of windows biggrin.gif

Thanks! smile.gif

Sure, don't make any problem about that test, its very old 2010 and probably its not desing for this generation - In practice with this setup of freq and voltage, never have a crash, artifac, memory error, over temp, etc.-

Something I read a few post ago was people with a problem when leave the PC alone, come a few hours later and the system was crashed or strung up well I have that problem in the past, its related with Wattman and the voltages.-
I say probably 20 pages ago, Wattman and GPU Tweak II have problems with that to solve that problem I put in Wattman the last 4 stages at 1175 volts (the max) and the final voltage set in GPU Tweak II in my particular case 1200v (1.20v) and the problems dissapear.-

I run several mv over what would be stable if the clock were power state 7 and haven't had a problem since. So about the same solution.

Thanks for your help. I still might have vmem issues but I haven't found a quantitative test that tells me so yet. Do you have suggestions? I've used VMT, memtestcl, CompuBenchCL, specviewperf, PassMark Performance Test DirectCompute. There might have been some artifacts in CompuBenchCL's T-rex but I don't remember what it's supposed to look like.

The only solution i get for mem errors, was use the HWiNFO and play Metro Last Light, was the best mem error finder, if you play that and dont have memory errors, are you OK my max mem freq with stock mem voltage was 2170 mhz, more than that - Memory errors.-

I don't get memory errors in hwinfo, but the following two problems look like memory errors:








Those are the only three places where I see what appears to be obvious video memory artifacts. The ROTR issue is only obvious with DX12 HBAO+ and SSAA2X or higher. DX12 utilizes a bit more video memory than dx11...

how much mem freq are you using ?
