C_N,
I just did a 15 minute prime blend run at 5 ghz to check the vdroop, because I felt the above example wasn't realistic for what you run your own chips at (since HWinfo was able to monitor the voltages).

BIOS voltage was set to 1.445v. LLC1
here's what I got.



So just as I thought, the board droops the idle voltage more at higher voltages (but as far as I know, ALL boards do this). At 1.25v LLC1, the idle voltage was 1.248v, a 0.002v difference from BIOS (basically, none), and load 1.224v, a delta of 0.024v between idle and load.

At 1.445v, idle voltage was 1.428v, load 1.404v. 0.17v difference between BIOS and idle. The idle to load voltage delta remained at 0.024v.

Didn't test it, but I can assume LLC2 will have the same idle to load delta (hopefully), but the voltage rising at idle (to around 1.462v idle, 1.484v load).

That's if everything goes by the books...
Is this still acceptable or is this a disappointing result?


BTW I stopped prime blend on the next batch loop (256k), after 512k passed (yes I know it was only 15 minutes) because the temps went slowly up to 82C, and that was too much for me.

BTW 4.5 ghz was going blend at 1.236v load (1.265v BIOS), stopped it at 15 minutes (ran two 15 minute tests)...guess that isn't bad, is it?

(My first run passed the first loop at 1.224v load, so I decided to get y and set the BIOS to 1.235v and try to run blend at 1.211v load. Fat chance. Rebooted fast. Tried 1.25v bios (1.224v load) and it rebooted a minute or so into the test. Yay for instant degrade? Set it to 1.265v, ran 15 minutes fine, so I went to 5 ghz and 1.445v bios, ran 15 minutes at 1.404v load, then temps got too hot on 2nd group, went BACK to 4.5 ghz and 1.265v bios, ran 15 minutes (again) at 1.236v and decided to stop wearing down the chip.

I know it's going to degrade more (like yours have done), but if this chip winds up being reasonably stable at 4.5 ghz 1.245v load, and 5 ghz 1.414v load, that's a pretty decent chip, right? (but not "low voltage" like some...)

(Boots X49 without PLL, X50 causes instant OC failed error).
