Gigabyte EX58-UD5/Extreme Discussion Thread

more testing under water with a 3842A937. why did I wait so long for a WC setup

Try Linx, i have a 3842A and was about 8 hrs stable, but linx crashed it in 10min, i need 1.420v vcore to run stable at 4.2 although for 24/7 i have it at 1.375v at 4.0ghz 100% stable.

No the mobo will not shut down the computer if i7 overheats. But the i7 will shut itself down at around 120C, or about 20C over tjmax, if throttling fails to maintain it at 100C from catastrophic cooling failure.

I use realtemp and set my cpu temp at 90C and gpu at 80c, so in case of a pump failure/water cooling failure, realtemp will shutdown the computer. I have tested it many times, works great. You can get latest version in this post:
http://www.xtremesystems.org/forums/...postcount=3443
go to settings, alarm, set to bat file... RTshutdown.bat, then enter any temp for cpu you want. Also if you have nvidia gpu you can enter gpu shutdown temps as well. And just place realtemp in start up folder or use task manager to have it start if using vista or win 7.

good tip on the shut down in case the pump fails I just set mine.

I Agree, but isnt there an options in bios to reduce both power and multiplier? sure it wont shut off if i think moore

good idea actually, im also on water so, failing pump or just something wrong would like me to turn it off, though i leave it on often when im not home.
better put this app to startup or something even though its ma min prog, doesnt coretemp shut off too?

cheers.

[Aberration]

The MoBo wont shut down the system? Are you sure?

On my R2E I set the temp to 90C. Once my wife had turned the fans off on my radiator while I was gone on a trip, she couldnt figure out why the comp keep shutting off.

The UD5 has similar options in the BIOS for CPU temp.

with the same procedure of the ud4, the mod wok's for transforming an UD5 to a EXTREME!!!!

same procedure but using EXTREME bios!

work good on my board....

NOW

[andyr(uk)]

Which port is best to connect a bluray drive to, the Gsata or the sata 2 , i only have the sata 2 enabled at the moment, Thanks

Jupp, flashed mu UD5 to Extreeme yesterday to! with F6i bios, works so far.

to extreme world....

What is the benefit of the extreme BIOS over the UD5?

Exactly - what's the point?

[Tommy L]

just becouse it can be done! and had to try.. must have something to try!

[Andrea deluxe]

What is the benefit of the extreme BIOS over the UD5?

better memory performance with same settings

[tipes]

better memory performance with same settings

Perhaps you would care to elucidate a bit more on that statement - what exactly are you suggesting?

My only complaint about my UD5 is that it fails to do EIST properly. That is, at Bclk above 139, My vcore voltage does not change
dynamically as designed by Intel (although the multiplier does change). Below 140, EIST works right everytime. Has anyone tested this? Results? I reported this bug to Gigabyte and they told me to load optimized values, then EIST will work. Obviously are they are in denial if they think any end user is going to cripple his board's performance by grossly underclocking it. I've tried many bios, all crap out at exactly 140 Bclk. Anyone get this to work at a normal Bclk value?

On the Extreme, CPU voltage throttles down only if it is left on auto in BIOS.
I'm guessing it's the same on the UD5

I believe that is correct across the board for all models/series. Never used it myself, but I think that is by design how it functions.

[tipes]

From the limited feedback on here about bios F6E for UD5 it would seem that it is not good, but we have not seen a new bios for UD5 for a while - anybody know what is going on?

I have not tried bios F6E myself as I am reluctant to because it still does not resume from S3 sleep mode, requires higher voltages for same oc, and to cap it off ithas the flash problem as well ie not easy to return to a previous bios.

Come on Gigabyte lets have a decent bios for the UD5 please.

Any comments?

hy guys, this is my 3836A : http://forum.crazypc.ro/attachment.p...3&d=1232561232

The pic is from Ianuary 21 2009. I used a CM z600 + 2x120mm Antec TriCool @ High for cooling the CPU. The bios was F5f if I remember well.

yes I have the same Eist works till 139 from 140 up it's a no no, sucks

965 btw

[ReverendMaynard]

It's not meant to be used with overclocking, plain and simple. 300 posts on this same subject...it's getting old.

I really don't understand this thread. 90% of the ing is about power saving options and how it fails when overclocking. The two together just sounds absurd to me.

If you're conserving energy...is the i7 even a wise choice?

[annihilus]

Offcourse it should work, when you don't need the horsepower it should clock back (this works) but because it fails to lower the voltage the fans have to be on higher then necessary

Can you imagine your high end gpu doing this?

no it should work, that's why we buy these highend boards

and I can't flash my bios back, it crashes ... sucks

does Eist work with the extreme bios over 140 blck?

Point taken. I've honestly never used it. It's the first thing I disable and have since the E6600. That is the 10000th thing that I would look for in a $450 board. And honestly, I wouldn't care if my GPU's didn't downclock either. It pisses me off actually, and I am positive it affects benchmarking.

There are a few dudes here toting that they have low voltage/high overclocks. The need for power saving options just seems ridiculous looking at this forum and the bigger picture of overclocking.

[Hornet331]

I also dont really care for idel consumption since my computer is always under 100% cpu load, but load consumption could be a bit lower. 350W 10h a day eat quite some money. (~230€ a year) would be worse with 24/7.

[PC_User]

Try Linx, i have a 3842A and was about 8 hrs stable, but linx crashed it in 10min, i need 1.420v vcore to run stable at 4.2 although for 24/7 i have it at 1.375v at 4.0ghz 100% stable.

I'm at the same settings as you also with i7 & UD5. My batch is 3841A.

[annihilus]

Sorry that I am going to say this but imo an o.c. is worthless if things stop working as they supposed to

I now have an o.c. of 4.123 Mhz this I consider my stable o.c. my 965 can do 4522 easy and maybe more but not with gigacrap if things stop working

If I raise Vcore beyond auto Eist stops working, If I go beyond blck 139 Eist stops working, I am mobo limited
