Well, I do :)
But I have electronics background from school. Funny description always helps understanding things.
200amps seems kinda high to me, as well as 100amps. I dont know of any PS that can put out that much power.
Or am I missing something?
haha thanksQuote:

I all of a sudden thought hmm can i make it like a comic book? i honestly have never read a comic book, so i am not too sure if its any good. Of course we never really covered SMPS DC/DC as much as I have had to learn on my own, but its been very interesting.Quote:

Anyways during my testing i found that the CPu can have the VRm pull upto 260watts at 4.2ghz when i set 1.63v. I did some pretty harsh testing, i am surprised it lived. I tested out things such as claims that go the DrMOS are to blame for the droop, which is incorrect, b/c i did the mod, and the voltage increases under load, just like it does for the CPU-NB voltage stock. Then ppl said the heatsink gets hot, and i concur it gets very heated, i cannot touch it when doing extreme testing, but the DrMOS lived with hours and hours of extreme heat and no good airflow, i used the stock cooler ......Quote:

Apparently you have to update the backup BIOS manually to make sure it's the same revision as the main BIOS.
http://i132.photobucket.com/albums/q...th_ud5bios.png
To get the system Information window press F9 in the main BIOS view
To update the backup BIOS press alt+F12 when booting to get into the backup screen
Before updating my backup BIOS was at version F3.
http://i132.photobucket.com/albums/q..._ud5bios_2.png
I didn't know this and assumed that the backup BIOS was automatically updated when flashing a new BIOS
using QFlash, which is the official recommended way of flashing.
Sometimes it pays to read official guides on how to do things :shocked:
OMFG. Better not post that usbscope jokes in reviews. Seriosly, PLEASE.
I know, you will post anyway, but then at least set proper probe mode :D

don't insult my scope, at least its not a stingray :), it actually has very good specs, better than one used on sites for PSU testing, and what I am measuring at isn't even at its finest resolutions, 20mv/1ms is nothing for this scope. If you check USB scopes are almost everywhere now, they even use them in universities. BTW if you tell me not to use a USB scope in my review, you should tell every review site that uses them, and I don't know one that doesn't. Times are changing, there is no need for my to haul a rusty used POS to measure ripple.Quote:

I like the pass fail test, i run it and it tells me how often it passes the threshold i set, it is very interesting to see max ripple spike, and then see how many times that spike occurs, the results are surprising. I can capture clear images, record videos, capture 10,000 data points whenever i feel like it. Apart from that I can run FFT tests and so on. From my previous use of desktop scope at school, this scope is just as good, if not easier to use once you read the software manual. I also don't have to worry about isolating the ground. It might not be a $1 tektronics unit, but its good enough. But wait how about I use the same timescale for all my testing......... i looked at your review a bit closer this time Tin...
its in AC coupling, what are you talking about? you want me to measure ripple in DC mode? LOL
I am using the same timescales you used, and ill test the UD7, and if my results are like yours then nothing is wrong, but I am not going to go measure most at 1ms and then switch to 40ns for one.
No comments.
If you so sure about very good specs of USB scope (there are few of them which are good, but they are priced much more than few hundreds of bucs, and still limited compared to normal desktop scope), why you even bother me with PM asking what is wrong, and how to make it right?
I don't owe you anything, nor other reviewers sites, they can use any devices they want, even ancient plotters if they want to. Somehow I wanted to see your reviews better, that's my fault :)

I will not help you this time, take care of yourself, you have EE background in university, right? It's very basics.
Now you see numbers and nice graphics, and do wierd buble-speach images, but you still unable to see what that numbers mean.
Sorry for being wrong, scope is not a problem in case of wrong meas setup, no matter if it's done by USB or 50k$ LeCroy, it will be same wrong. Continue please, let other EE have fun :)
i am sorry? :shrug: what you want me to do it at 10x instead of 1x so the load on the PSU wont be as much, don't worry Tin. I know there is a lot of noise on those results, besides under transients during wPrime i did end up with about 110mv Vpp, i am not fooling anyone. And FYi i know how to use a scope very well, please don't insult, those were not my final images. You enjoy trying to discredit me, don't you? :) i can add smile faces as well when I feel like being :).
I understand that 10x has great impedance on most probes than 1x. But I have a problem with using 10x, and that problem is the signal I am trying to measure is super small, and 10x decreases my accuracy 10x. So its give and take, i am working on trying to find a better probe(one at 1x and with very high impedance), but for the time being, I will show 10x compensated and 1x compensated, and i know how to compensate a BNC, and yea my USB "junk" as you call it has a 1khz compensation signal
Anyways Tin, at 1x i could be loading the output i am measuring, as 10x is much moer typcial and loads my circuit less. But i am loading 100-200watts, i doubt it'd make much difference, so Ill do a little test.
over here some guy posted the BIOS F4C, said it improved his vdroop a bit.

New BIOS for the UD5 ... : http://forum.giga-byte.co.uk/upload/...XA-UD5_F5c.zip
I have no idea what's new or changed. Running with it now. No change in vdroop :down:
Will look for new options in the BIOS.

I heard of vdroop issues with the new gb 990fx boards but I didn't think it would be anything like what I'm experiencing. Bios setting is +.2v (stock is 1.4) so effective 1.6v. Initial idle in windows is 1.648v, load in p95 is 1.552-1.564, during 3d its around 1.62, then later idle is 1.472-1.488. I really don't understand WTF is going on with this board. I'm not super concerned with the voltage with this chip, max temp on p95 is 44c, but I am concerned about how this could affect BD.
System is stable but these voltages are crazy. Also, first boot bios sets stock voltage to 1.475 (should be 1.4). After entering windows, restarting, entering bios, default voltage drops to the correct 1.4. WTF is that? Comments/concerns/ideas?
my friend also mess up with those droop on UD7
Just built a new computer for my GF with the 990FX-UD3, now i need the new bios since F2 bugs out on boot if i try to enter bios.
Already installed windows with ACHI on a crucial M4 128GB so i dont want to disable achi either.
I believe you have turbo core on or some C1E or some type of power saving for idle to drop to 1.47.

Am reviewing the UD7 atm.
The 990FX-series from Gigabyte supposedly have trouble with unlocking too. I'm running an PII X2 555 on X4 B55 3.8GHz usually. UD7 doesn't accept X4 (but any combination of X3, 123 // 124) under load. Prime95 and LinX on X4 stock freq is insta-freeze, whilst any X3 runs 3.8GHz+ no probs.
Also in on the massive vdroop / vdrop.
Finnally finished up my review here
Great review sin! The results from the vdroop mod is very interesting. It would be great if they had worked in a bios option for that instead of requiring a hard mod. I guess we'll see what happens with zambezi (at least before modding myself). But post mod the board does perform exactly how you'd want, increasing voltage based on increased load. Right now the board does the exact opposite!
So to keep idle vcore down, but keep 3D stable (tested w/ SC2, vantage, 06) I'm using these settings: CnQ Enabled, Turbo Core Off, Bios V Core: +.125 (base 1.4) = idle 1.4v, 3D 1.545v, prime 1.477v (fail immediately, BSOD), max under light load 1.573v. This isn't ideal but it seems a lot better than running 1.6v+ 99% of the time. Also, CnQ is adjusting multipliers (4x-14x) without issue. Maybe others will have similar... success? :shrug:
Hey thanks, but honestly i run without the mod, as its pretty harsh on the increase voltage. Its the exact opposite of the vdroop, so you gain what you would lose under droop. When I did my max OCes i did all that with vdroop and with the vrise instead i had no luck in increasing the OC.
I honestly recommend not doing the mod and waiting for a better BIOS or somthing.
Currently in contact with Gigabyte engineer via PR.
Issues:
- Full unlock of X2 to X4 gives instant freeze at load
- Voltage issues
New BIOS:

i am ready to buy a mobo, leaning toward the ud5 but if they arent going to fix it probably just go with chV. so anyone know what their plan is?
I'm sure there's 'something' different to it, but in the future I'll be asking for changelogs or so, because the F4g didn't do anything voltage- nor unlocking-wise.
I don't know whether they can fix the droops through BIOS changes, but if they can't they simply delivered a badly designed piece of hardware. In regard to the unlocking, the engineer responded that they use the method as with any previous models with the same option, so it should work. To that I replied it still doesn't, so something must be different ;)
I'm willing to give Gigabyte a good while on optimizing the board, as there won't be many early-adopters (due to Zambezi not being released) and many that obtain a board of this calibre won't have a petty X2 that happens to unlock to X4.
Noted :)Quote:

I had the same locking up issues with a 550 on my ud3 which ran unlocked all its life in a previous board.

The unlock issue is because of the changes AMD made to the AGESA code. It can be fixed with some BIOS rework though. I had the same issue on the C5F and ASUS had a fix to me within 3 days of me reporting it.
I've also updated to this bios to see how it feels in terms of general stability and oc.Quote:

This is how vcore performs in my system during prime95 latest version 64 bit torture test, in idle goes up to 1.456v
i have bios F3f for the UD3 if anyone is interested.
Not sure on the changelog but its fresh out the kitchen, have not had a chance to try improve my overclock.

Thank you!Quote:

it appears that the higher you set the vcore the more droop there will be. also the move vboost you will have at idle.
ex. lets say you set vcore in bios to 1.4v, in idle it may be at something like 1.43v but at load it will drop down to 1.35v. now if you bump up your vcore in bios to 1.55v then there will be bigger boost at idle and bigger droop at load so if you set 1.55v in bios idle may sit around 1.62v but load will drop all the way to 1.45v.
i am not positive on all this but from the research i have been doing about boards this the conclusion i have come to. i picked up a ud3 since it does not use the new driver mosfets so it does not experience the vcore issues. hopefully giga will release a rev.2 or something, i may switch to ud5 if they do.
just thought i would post what i have been finding in case anyone is still interested.

yes 3-4 of my friends sell UD7 (VCore issue)
im having no luck unlocking any core at all with my UD3. Got a xII 555Be and the cores dont even show up. Enabling core unlock freezes after saving changes and restarting. I was able to unlock this chip on my previous board. I think Gigabyte has a broken unlock feature. Has anyone been able to unlock anything with a gigabyte 9xx board?
It's a common problem even with the new F3G bios but i'm slowly finding stability improving like my 550 unlocked to 3 cores will last for hours on load but then randomly crash.Quote:

The board still unlocks the CPU to quad (from dual) and the wall is on quad enabled - haven't tried HTT performance on locked (dual) yet.
Previously i had a GA-890GPA-UD3H that reached 4GHz on the same cpu so i'm a bit disappointed in Gigabyte here as they have regressed somewhat.
I remember reading that someone on another forum mentioned that F3f performs well on the x5.33 memory divider whereas F3g performs well on the x6.66 divider - haven't tried that myself yet but it's my next step to see if it's RAM that's limiting HTT clocks.
I also have the searingly hot northbridge and get annoying clicks out of my speakers (realtek and HDMI). It's unfortunate that the 990FX board with the best slot layout is really a POS for the CPU we have available.....i'm just hoping it's completely geared to bulldozer so K10 is suffering a bit.
Im still on the B bios but words cant describe how dissapointed i am with this board. Forget about using a USB keyboard with it. Major instability. Come on gigabyte its 2011! And with no changelogs posted im reluctant to spend alot more time on this POS and swapping bios's. Did anyone notice any kind of improvement with the newer ones?Quote:

To me it looks like people are too sensitive to vCore fluctuations. For me vCore issue never caused system instability and OC I'm getting out of this board is slightly better than what I had on ASUS CH IV F with no vCore problem.
Good experience all around in a system filled with hardware like: RAID 0 array, SSD, Blu-Ray, HDDs, USB cam, Logitech G15 and G9, Flight Sim USB stick, iOmega REv USB drive, 2xHD6970, 2x4GB RAM and so on.
BTW my computer now is under 100% load 24/7 for good month thanks to BitCoins, not a single problem.
Of course I understand other people can experience issues on same product and personally feel Gigabyte could be doing better on BIOS side.

EDIT
Still overvolts at Idle and drops around 0.1v under LinX load, so no change there.
Haven't seen any changes in BIOS so far.
Ok, bit of an update here of my testing with UD3 over the last couple of days.
F3g beta bios didn't make a difference to me.....couldn't overclock well at all and bios definitely feels buggy. F3 full release then downloaded and this is definitely much much better. As i suspected there was previously something going on with the ram. I can now overclock much closer to what i could previously (with 890GPA-UD3H) and if i left the RAM timings set to AUTO the timings set were MUCH looser than F3f/g.
Then tried F4 (gigabyte must be on the coffee as that's two bios in two days) and it's exactly the same as F3 performance-wise.
The board still seems to have a problem with the high HTT though and successful passes of memtest/intelburn then turn into a no boot when board is restarted and i then have to clock the HTT back up again as it resets to stock. Frustrating.
The bios is definitely getting better but gigabyte are taking their time on what is a known and already very mature platform.
I'm sure that CPUZ/HWMonitor can't read this board totally correctly as my VCore isn't reported properly in either. It's not Vdroop as a 0.2V drop wouldn't allow Intelburn to run and pass although i might be getting some droop but not be able to tell without getting my DMM out.
I just hope i don't have to go through all of this bios work when bulldozer hits.......

I am wondering if ASUS's VRM are the problem, or if it is the northbridge is heating everything up so much ?

Yes I would like that answered as well, I'm upgrading soon to either the ud5 or the Asrock Fatal1ty board(which is deemed one of the better boards). I love performance but i also love aesthetics.
Yup:mad: my 550 and 555 are not stable yet Unloncked @ 4200 or even lower
My Ud4p Unlocked them flawless:yepp:.
On this Ud5( In Normal Core Mode) thier just fine above 4200mhz. I am liking this mobo despite that unlock buggyness . Raid and the boot up times are nice, upgraded to 2100mhz ddr3 and having Xfire in 2X16 vs 2X8 for dual cards is huge. Tweaking mobo with some Voltage. It does OV a little and i run my Vdimm on ram a little higher too.
F5 bios im atm determined to get my 555 fully stable while unlocked . Then ill need more cores hahaa
No luck with unlocking my 555 on ud3 with latest bios. As soon as i enable core unlock it doesnt boot. Why have this option if it doesnt work.
most 900 series mobo any brand have core unlock problem
good bios update help
my 555be only unlock 3:), using bios F5 and cant wait for bulldozer.

@ 4300 1.65v cpu/vcore and Nbvid@1.35v @2700mhz with 1800mhz on da ram ....

UD5 needs a better Bios but i am unlocked again above 4200mhz:D
Haha gOtVoltage, I love your CPU
However 1.65v for long will pretty much insta-degrade and kill CPUs over time. Since Thuban, and since ~week 1015-1020 Deneb, AMD has switched to a Low-K dielectric layer (at least we think so, since these newer Denebs act like more like Thuban than ever, and definately not like early C3 deneb) in their CPU's for lower TDP, working voltage and better OC ability.
1.5v is really the limit for these things on air, I'd feel sort of safe up to 1.525-1.55v on water. Validations not really past 1.6v.
A lot of newer Denebs are hitting air/water frequencies like never before however it seems to me cold scaling has suffered a bit. (Thuban worse LN2 scaling vs better air clocks reveal this)
Some CPU's even do 4.1-4.2 Ghz on a measly 1.45v or less, it's crazy stuff. Some guy here unlocked his X2 to X4 and his CPU did 4.2 stable at 1.45v.
Unfortunately my Thuban does "only" 4.1 @ 1.5v+, 100 to 250 Mhz behind most CPU's. Hopefully my luck of bad CPUs will turn around with FX.
As far as needing more voltage to unlock?...not really.
These 900 series boards are very touchy as the unlock is part of AGESA code and manufacturers are focused on FX right now. Heck, performance and OC ability is bad on them too. However, if a CPU doesn't run stock frequency on stock volts with an unlock attempt, more voltage is not going to fix the problem. It's not worth unlocking at that point.
990FXA-UD5 new bios ....

what does it mean d???
I dont know but will try the F6d soon... hoping for a more stable max unlock biosQuote:

This CPU is epic. i cant wait to try a 6 or BD core now that i have a true ddr3 AM3+ setup :)
UPDATED now on the F6D
Ok F6D is way buggy with ht and volt settings,, multiple reboots when trying to get 1800mhz ram stable at 4300mhz... atfter some tweaking i managed 2700 on the Nb while at 270fsb using 666 divider for 1800+ on the PDP 2133 sticks.
This B3 unlocked dosnt like to go past T1 @1850mhz too much. Also Running loose or tight , swapping T1 and T2 are very close to the same between F5 and F6D Bioses.
F6D you must manually set the Ram! and set Ram volts up or down a setting from where it should be.
Prepare for some tricky HT and Ram multipliers and dont use auto for the Ram.
In all the Bios is workable and i have yet to go above 280FSB unlocked.
, Also decided to see what the mobo has foe volts!!!!
It can and will volt the Crap outa whatever you want ta cook:up:

Maybe its Beta version D? I have F6E for my GA-990FXA-UD7 motherboardQuote:

Does anyone know if the UD3 can lock individual cores of BD? Like done here,
http://www.xtremesystems.org/forums/...-Threaded-Perf.
can i ask you why you want to do that? i am just curious
I dont need another PC, just want something to toy with. Want to do direct 4 core comparisons against my 2500K and Deneb, along with some other tests. Gives me something to do. Also, if the single threaded performance really is that much better, it should be cooler then having all 8 threads active and OC a bit higher with air/basic water.Quote:

TO UD3 OWERS:
If you load f5a bios onto UD3 make sure you have another bios on flash drive in case f5a gives you problems. for me it would not boot to OS, just hang on "loading o.s." screen and it seems like a lot of ppl have had that issue with f5a. i loaded f4 onto it and its working fine again. i know f5a has latest agesa so maybe it will be fine with BD but it gave me problems with thuban
990fx UD5.................. F6D bios is touchy................ after a few days i decided to go back to F5
As of Today ,,F6D has been removed from the Bios list and F5 is now the most recent!. Unlocking does fully work with F5 and you just have to tweak settings for some Vdroop. hopefully well get a Bios that helps the Droop and gives us a little more tweakage.
They also removed F6E for 990FXA-UD7 motherboardsQuote:

There are many variations of the BIOSes, the letters really don't mean much for users. The thing is that the latest Betas for BD were taken down, and I am to tell you guys to use the official, as that is what GB wants. i think those betas were up so reviewers could use the latest microcode.

sin does this GA-990FXA-UD7 F6E look legit? http://rghost.net/25234551
Im a bit worried.
lemme know if you think its fishy I found it in this thread

OK there is a new F6 for 990fxa-UD5...
The F6D didnt work wirth beans and i am others have unlock problems with known good unlockable chips on UD3 and so forth...
so far none,, not one of the official or beta Bioses work to unlock my 555 or 550 (((((with out crashing..))))))
.Both Chips work past 4200+mhz on my UD4P!!!!
These are unlockable chips that work 100% stable on other Mobo's......
GIgabyte,,
please,,
at least one working,,
Unlockable Bios would be nice,,
a good BD bios while your at it too lol,,
smashes head on desk,,
You know like you had for 790/890 chipsets..!
