Gigabyte P55-UD2..Core i5 750

What a day, got all my components delivered, then when I started putting everything together I realized the HSF I ordered was broken... O no, no i5 goodness for me then... Well, I got the tools out and disected an old intel E2180 stock fan so I could use it on a LGA 1156 socket... it worked, I'll post pics soon.. :)

Components:

Gigabyte P55M-UD2
Core i5 750 (Oem)
2 x 2GB Ripjaw 16000 C9

Testing...

Fan mod? owa thats cool:D

First bit of testing, modded cooler isnt bad, but it's not good either...

keenan,whats the stock vcore on that chip when
everything is at defaults,in the bios what does it set it to?

Stock Vcore is 1.175V

Here is a quick 4Ghz shot.. ;) 1.232V

Not bad voltage at all :)

what batch does this cpu have?

Hey Kylzer, fancy seeing you here.. ;)

Anywho, that wasnt too stable, could'nt even run 3dmark..

But this was tho...

I dont know mate, I'll tell you once I install my watercooling...

Waiting for the mount, still on stock intel cooling..

Hellos :)

i just found out i could run my i7 with lower vcore if push the QPI up to about 1.38 -1.4 maybe you should try that ?

Can anyone list the safe voltages for i5..?

There are quite "officially" high.. 0.65v-1.4vhttp://processorfinder.intel.com/det...px?sSpec=SLBLC
Intel specification for i5 750, i7 860&870 so i guess 1.45 vill be safe too..
So a good 750 (vid 1.100,1.125v) could probably reach 4.2-4.3ghz with 1.4v
on air with a good cooler...:up:
Seems to me that there are some chips with low vid that are kind of equal with midrange 920 DO chips on overclocking, i mean 4.2-4.3ghz it is possible 24/7...Good news..:up:

My roommate got this mobo, and the same processor. I assembled it for him, and it POSTED successfully. During Win 7 setup I got an error message, :banana::banana::banana::banana::banana:ing about some IDE I/O issue, so I adjusted the cable and when I tried to reboot again, all it did was start up all the fans and keep rebooting by itself. I tried removing all the components, installing them one by one...nothing... tried different sticks of ram in different slots, nothing....Any ideas folks?

You tried a bios reset..?

also try booting with bare minimum of components installed, just everything you need to get into the BIOS, and try 1 RAM module too.

Boredom sets in... :eek:

Nice i makes me wana go have a Super pi run :)

nice wants me to upgrade :)

BCLK ~205 24/7 in case possible ?

What's the question..?

hey guys,

just had my board fail after 3 weeks, can anyone list there full bios settings, got an i5 week 24 ,

just want to check i havnt induced this fault

http://img218.imageshack.us/img218/3589/gigap55cpus.jpg

the chips in red have popped, at least 3 or 4 of them..

hopefully i got a dodgy board as it was running all on auto at stock volts when it popped. never had it above 1.375 vcore!!

cheers

Gordy!:down:

Guys,

Anyone who owns Gigabyte P55-UD2, There is new bios updates, Maybe beta bios fixes from pop bad chips on board ?

What bios version do you have now ? did you happen know there is new beta bios F4g might save your board from pop that chip, maybe too late ? take it back for RMA if you can.

Dangit, popping MOSFETs...not good news :( I've read at least one other person (Evilsizer @ OCF) had a failure although I don't know if it was the MOSFETs. What kind of cooling and/or airflow did you have around that area? Would it be helpful to put sinks on those chips? They are pretty small though..

I've been looking around and was really drawn to this board, the combination of features I'll actually use (I don't do multiGPU and I like the slot spacing for very large passive or quiet GPU cooling and my PCIe sound card) and price was perfect. But dying MOSFETs is bad bad. Anandtech said they had theirs running perfectly under (non-xtreme :p) stress and fairly good oc's for a while, maybe they got a cherry board? :-/

Guys,

Updated...bad board burned out mosfet link at http://www.tomshardware.com/reviews/...d,2436-15.html read on.

I still have i5 750 sitting on table for while...I am also backoff plan to buy Asrock P55 Pro, still looking for better brand of mobo, take my time before I get all info first.

A friend of mine has Asrock P55-PRO for 4-5 days...for start he keeps his 860 at 3.8ghz 1.288v http://valid.canardpc.com/show_oc.php?id=744001 and nothing happened.
I think that it's not a general rule, there are some defective boards...at all manufacurers...Gigabyte, Asrock, and MSI.
I mean even high end P55-UD6 -229$ socket "burn" so...
A good motheboard if you can buy is Asrock P55-EXTREME 139$, the cheapest P55 SLI motheboard.

Tell your friend, what rev board does he have 1.0 or 1.03 for Asrock P55 Pro ?

thanks for the replies dudes.... firstly i was on this bios, made no difference! but...was sure it was to solve ram compatiblilty issues, my rig is/was a fully ac ryan meshed sides/top a+blockbuster case (large mesh holes so like having case open really) a scythe zip zang 2 cooler which is massive and awas a vast improvement over stock cooling, also this has a huge 140mm fan on top which blows air down and over the top of the chips, the ram i was running was rip jaw 1600mhz (happily runs over 2ghz) , graphics wise a mere gt2 250 for now and psu issues were ruled out (tagan piperock bz 1100w)

i know going by my settings i wasnt over doing it, even when i was tweaking it....
:confused:

I thought that maybe the MOSFETs were more likely to pop with i7's, more power draw due to HT. But ninjagordy had an i5 :( This looks to go a little fursther than just the occasional board failure given what the THG article says.

The anandtech article says this board was 'originally designed for OEMs and wasn't meant for retail release' Well, OEMs don't overclock :P So maybe they designed it for basic Intel specs or stock voltage (not AUTO which can sometimes jack voltages) rather than high overclocking specs. So much for 'Ultra Durable 3'

Looks like a FET (or controller? can't really see) blew on each phase of your VR's. That means that you were drawing too much current. I'd bet the board is shorted somewhere if you have it on stock volts. Either that, or it wasn't on stock volts ;)

Keenan: whats is the max BCLK that mobo can do?
