GD80/UD6 and 750 at 5.2G
Time to start using the Hwbot forums more often; it's too quiet in here!!
 I've been testing the GD80 two months and a couple of days, but only recently I was able to lay my hands on a retail 750 (thank you, Leona from MSI). Got the chip in Beijing, went home, was bored, so threw it under some LN2. The whole session lasted about 5h maximum and wasn't particularly focussed on anything besides getting familiar with the retail i5. Anyway, I'm done talking, let's give some numbers. Chip:  10 sheets of paper towel - no condensation whatsoever. What's all this BS about eraser being the best  Results      For those who are interested, I also did a quick Everest benchmark. This was after I finished the 32M run.  Everything can also be found at the bot. I didn't push VTT higher than 1.55V as the board had some instability issues. Forwarded everything to MSI, so let's hope for improvement. It does seem, though, that all 750's have inferior silicon quality compared to the 800 series as almost everyone maxes out at around 240-246BCLK.

Coldbug and coldboot are a bit of an issue; not only with this motherboard, but probably with the chips. I did all these runs at temps between -60°C and -70°C; -80°C was still pretty much stable, but anything lower than this results in complete instability
Coldboot wasn't a problem as long as you don't mind resetting the CMOS. Everytime I had issues booting I cleared the CMOS and the board could boot up again. Btw, this combo was very vcore/vtt sensitive. You need to find a balance between vcore/vtt to boot, preferably setting vtt higher and vcore lower. With the DIP switches you can adjust the volts quite easily and that's how I did it: low vcore/high vtt boot, +0.1V vcore via the dip switches just before I enter Windows. Oh, right: issues above 1.6V VTT!

I want to say it's the chip, because a lot of people are pointing in that direction, but I can't help but thinking the board is maybe a bit to blaim. I will test my 750 on the UD6 this weekend, so I'll know for sure the board was holding me back or not.
Let me know what you think; i'll forward the stuff to MSI HQ anyway, would be cool to know if I'm the only one having issues or not . Btw, don't try high PCI-e clock, it doesn't really work. 102-103 maximum ... with earlier biosses I could get it running at 110MHz, but it seems they've "fixed" it, hehe. Doesn't matter anyway, it helps maybe 3-4MHz BCLK.

Tested the more more intensively last night; a couple of remarks:
- Had a lot of issues with memory multipliers: couldn't boot over 1500CLx and higher than 1800CLx was quite unstable. Voltage/timing change/B2B didn't change this. - Before I used the 1.5B2 bios and this one had an issue with coldbug on the PCI-e. You know it's this issue when the boot locks at "2E"; just change VGA card from pci-e lane and you are good to go again. In bios 1.5B4 this issue has been fixed *hooray* - On single stage I'm limited to 237BCLK - 1.5B4 still doesn't allow me to use more than 1.6VTT The one score:  I just installed the UD6, let's see what that brings

That's the forced turbo mode function.
Ok, for 750, you have the following turbo modes: 4 cores = 21x 3 cores = 22x 2 cores = 23x 1 core = 24x To open up the forced turbo modes, set EIST to AUTO. Then, if you want 23x or 24x, set number of cores to 2 or 1. You can't force all 4 cores to work at 24x.
