I am new to the world of PCs, well, I've not had one since a Voodoo was good, so effectively new...
I recently built my first PC in 15 years or so: i5 2500k (4.5Ghz), MSI Z68 GD55, 8Gb Vengaence (1600Mhz), 2 x GTX460 1Gb.
I am currently trying to understand graphics card benchmarking and overclocking, what I should try, and what I should look out for etc.
My SLI cards are pre overclocked, and I have been using the EVGA precision tool to bump them further. I am currently at 830, 1660, and 2005 for Core, Shaders and RAM. This seems to be in line with what can be expected in reviews. Everything seems stable, but I am getting odd things happen on screen on teh 3DMark 11 tool. Here is what I have run:
* I have run Furmark, and it happily thrashes along, temps for each card go to approx 70%, no issues seemingly.
* I have run the OC tool from EVGA, and this works fine although I do get the odd artifact here and there listed, but I don't actually know what this means. I can get more if I turn on the CPU test module at the same time. but again, I don't know what this means. Oddly, although the top card gets s little hotter (which I understand), it also runs faster, generating 95%+ load at all times, whereas the bottom card often sits at 70%?
* I can happily play Crysis 2 with the DX11 patch and High Res Texture Pack on Ultra everything (Note, my monitor currently caps out at 1400x900), I'm not sure how to get it to show me a frame rate, but it feels very very fast and smooth, no issues at all.
* The Unigene Heaven benchmark runs really smoothly, just the occasional stutter but nothing other than that.
* But, when I try 3DMark 11, I get wierd green splodges that occassionally flash over the screen at random.
I'm sorry if this seems a basic question, but what are they, are they a result of overclocking too far, and other than irritating are they a problem? The fact that I only see them in 1 benchmark suggests that normal gaming is OK, it's just the benchmarks that are intended to really hurt that exhibit the behaviour? I presume that if it is a result of going too high, then the worst I can have is a graphical bodge on screen, and it isn't like pushing a CPU too far where data corruption will cause a crash? I do get lower FPS in 3DMark than Heaven at a lower resolution, so maybe it's just really really taxing the system hard.
I'll do more testing later with different overclock profiles and see if I can reduce them or make them worse, but in the meantime I'd appreciate any advice to a newcomer
