so more VTT is the answer? then probably at stock one board is giving more power on the VTT on. On the UD7 the CPU PLL is overvolted at stock. The VTT is exactly as is read.

the vtt on this board does not move at all from idle to load it is very solid

[Falkentyne]

Sin,as per your chart and Sergio setting ,my LLC level 7 for 1.4600V in BIOS,give me idle 1.5240V and under wPrime go up to 1.5720V?

wow...what happens if you use LLC6 instead?

[owikh84]

not on the M4E, I have a two sets and they can both run 7-9-7-21-1T-88 at 1.66, and with lower vtt, so there is no reason why they can't on the UD7 with the same vdimm

On M4E, i set 1.675v at bios translated into 1.66v in sensor tab, but actual DMM reading is 1.68v.

That is very odd, ill check it again, but i stated under my explanation, that there was some odd stuff going on around level 7 and 1.45v. As i stated i saw a jump to 1. 483v and then back down. It jumped around but i didn't use stuff like wprime and superpi, i used IBT and Prime and had them load for a period of time to get a stable voltage.

What you are seeing is most likely a spike in voltage. But that is very odd, i can't reproduce what you have right there. There is no way it can jump to 1.572v????? that is very weird. What does easytune says?

wprime didn't stress enough, i found that IBT stressed the voltage much better, you just have to wait a few seconds.

[stasio]

wow...what happens if you use LLC6 instead?

Level 6 ,1.4600V in BIOS=>idle 1.51.20...load 1.5360V.
Level 5, 1.4600V in BIOS=>BSOD
Level 5, 1.4700V in BIOS=>idle 1.5120...load 1.5000V.

[sin0822]

here youg o man i used Level7 and 1.46v set, and i used wprime.

try clearing your BIOS. I was looking to see if the voltage could actually jump that high, and i didn't see that type of action.

[sin0822]

Ok so what i posted above was at 4.5ghz, i went up to 5ghz now. I see more vrise, upto 1.502 on the DMM, 1.484 idle and 1.502 load, software shows 1.488v load.

I believe that as you increase frequency LLC also trys to compensate, that is the best explanation I can give. It seems that No ones results are the same, they just follow the same type of trend. This is because we are all at different frequencies, i did all my testing at 4ghz. Chanign to 4.5ghz changes very slightly, and then changing to 5ghz changes even more. i can redo my testing on 1.45 and 1.5v with 4.5 and 5ghz respectably or something like that. i obvuiously can't do 4.5ghz with 1.23v, or 5ghz with 1.35v.

[stasio]

Yeah,in my 5GHZ,Vcore 1.4700V with level 5 in BIOS, voltage in windows is 1.5000-1.5240V.

[sin0822]

interesting. Ill see how much affect the frequency has. Maybe this LLC is more dynamic than initially thought and it compensates differently per current which would be determined by frequency in short.

[Falkentyne]

Stasio:
youre using a B2 crossflashed to B3, right? That may have something to do with that.

I used 5 ghz and LLC5 (not stable in prime though) at 1.450v BIOS and I saw drop down to 1.404v at load (this is on a UD5 B3). 1.445v BIOS->1.390v max drop at load at LLC5.

I'm at LLC6 and 1.440v BIOS and keeping it there for now (usually was 1.424v in blend but saw drops down to 1.404, and 1.404 in small FFT too. Not sure if that will cause problems. I treid LLC6 and 1.445v, but I saw blend running at 1.440v and that was a bit too high for me.

[the_real_7]

actually on the b3 vtt is 1 volt lower as on the b2 it was exact

[the_real_7]

so far so good for my 24/7 setup , running llc6 with 1.460 , giving me 1.440 on load , will lower later but again passed prime 8 hours and did 40 linx passes


prime 8 hour pass

[andressergio]

thanks stasio so im not the only one with that seems that when programs dont stress much like SPI, Wprime etc vcore takes a hit acting like old LLC2 but prime, linx make it go down

as for me i had a bsod on IDLE so i put 1,425Vcore on bios giving me 1,452 IDLE and 1,428 LOAD

but maybe giga has to check that as from LLC5 im noticing that vcore going up

[andressergio]

Tony check on chokes you will see that gamming you will have like 1,5volts if not more...

confirm this so far stasio confirmed and me, he on wprime and me gamming

this is odd as will act like loading a bunch of unneeded volts

Wow sergio its still happening . . . I will check tommorow as these long prime session have me off my pc . . . if that is the case is it worth still running the new llc options

[sin0822]

actually on the b3 vtt is 1 volt lower as on the b2 it was exact

1 volt? like instead of 1.05 its 0.05v?
the voltage drops under load like LLC defines, try higher levels maybe it wont.

[Kent10]

Has anyone else noticed that with the new F3 BIOS (LLC Level 6), the Vcore seems to fluctuate more, at least in the software readings I am getting. I have 1.460 set in the BIOS and on idle the Vcore reading in HWiNFO ranges from a low of 1.452 to a high of 1.488. It is mostly on 1.464 or 1.476 but on the F3h BIOS (LLC Level 1) it was almost always 1.464 idle with very little fluctuation.

[sin0822]

Different load levels, especially light loads, create odd voltage readings, i found this to be true. but if you are complete idle, 0% on all cores in task manager, and then 100% full load, those are my results. I can't tell you what you are going to get when running superpi lol.

So my word of advise, either use the chart or get a DMM because there is no way voltage is always going to match, the idle and load trends will continue. There also is definitely no guarantee that B2 boards BIOS will work exactly the same, even though they should. Good luck, i found that Level 5-6 was pretty good for OCing, but yea voltage fluctuation max and mins are always going to be different, and they will be during different stages, usually not at 0% and 100%.

and sergio i saw that it raised to 1.5v it depends on the clock of the CPU though, i ran wprime and at 5ghz it went to 1.5v. at 100% load with IBT it dropped down, at 0% is was much lower than 1.5v. So that is just light load oddities. I doubt they will be able to do anything about it, and that is why there are 10 levels, some are really weird and some are really great.

[zsamz_]

glad to see you finally hopped on the sandy bandwagon, your going to like it, even if you do have to use a gigabut

after testing both the UD7 and the M4E I can say they are both excellent boards, and I wouldn't mind having either one, but it is a hard choice to pick one so I am gonna keep both of them

now all I need is a 56x or greater cpu

tryin out sandy more out of curiosity than anything else
and i got a good price on the gigabut ud7

good thing i got a few nice sets of ddr3

[Falkentyne]

Wow Andre what crysis were you playing? 1 or 2?
I tried crysis 1 just now and my vcore ranged from 1.428 (maybe 1.416)-1.452v (BIOS=1.440v LLC6).
(this is on UD5).

Sacred 2 fallen angel had a spike to 1.464v at most but was usually lower
And wprime had this range:



I saw you and stasio had crossflashed B3's, but Sin confirmed your result with a native B3...

[nijel]

Crysis 2 barely puts 20-25% load on 2600K like most of the games. But you can see your max Vcore.

[andressergio]

Wow sergio its still happening . . . I will check tommorow as these long prime session have me off my pc . . . if that is the case is it worth still running the new llc options

i still cant find wich one is good, i was happy on LLC7 but today BSOD on IDLE wich sux, then i went to LLC6 and needed LOAD 1,44 to pass prime 1h wich sux again i was passing it at 1,428 LOAD

for now i thing giga needs to adjust this new features, chips could be degrading if you play and load like happens to me

[nijel]

I'm pretty sure SB doesn't like idle voltage under 0.95-1V@1.6GHz. Starting to believe doesn't like high idle Vcore@ high speeds as well.

yea i think they down tuned these LLC levels all together. Who knows they might just take it back to Standard, level1, and level 2. Might be better that way. Level 10 isn't as strong as level 2 was in overvolting, level10 has much more of an offset, but not even close in vrise. I thought those 3 levels were perfect to be very honest, and I think they should take it back. It was just level 2 was overvolting too much and normal users without a DMM could kill their chips easily. Level1 was doing amazing.

I'm pretty sure SB doesn't like idle voltage under 0.95-1V@1.6GHz. Starting to believe doesn't like high idle Vcore@ high speeds as well.

I was starting to think they don't like high idle voltage either, it crossed my mind many times.
