That's exactly what I have been doing when finding a stable spot. I tuned the vcore using small fft for about 4 complete loops. I then moved onto the NB/memory and tested with large fft for another 4 loops, then ran 25 large linpack, followed by 12 hours of blend, so I can quite easily get stable as far as I'm concerned.
It's just the GTL tuning which I really thought I was getting somewhere with until I returned after this weekend and powered up with the same settings.
Like I've said, I got better results with -ve GTLs after I lowered vcore to make it unstable and blended. When testing and comparing -55,-5,-55,-5 (and upwards) to +50,+10,+50,+10 (and many combinations in both directions) the -ve ones (with a 50mv gap) gave me an average of 25 minutes of extra stability (well into 8k, and often into 12k, as mentioned before) which made sense to me (even though it seemed a bit odd given the VTT of 1.32, the 50mv gap, and the equation). When testing the +ve GTLs I got blend failures within 10 minutes of 1024 which indicated much more instability.
If I up the vcore to one notch below a completely stable vcore (1.45v when at 3.6GHz) and try to find the GTLs when I'm seemingly 98%+ stable already (i.e able to prime for hours before failure/reset) this is clearly going to take far too long. The trickiest thing is the fact it keeps rebooting which although seems like a sign of greater instability, doesn't help when you have to keep staring at your screen ever 30 seconds to find out how long it lasted or look through log files if you miss it!
The only reason I went back to tuning the GTLs after being 100% stable is because I read a lot about the GTLs helping to lower vcore if tuned right (although I understand this isn't always the case).
After discovering that -ve GTLs worked better and gave me 8K stability with 1.425vcore (I needed 1.44v with +ve) I thought this was worth persisting with, but after returning this weekend, it all went out of the window!
I'll wait for my PSU and see how things go from there and probably make a decision about what to do. The inconsistencies I'm experiencing is now the main problem I'm having, nothing to do with getting stable, I just want to tune it properly!
