Asus P5KC first look

[dinos22]

When you say 850 do you mean 1700MHz or literally 850MHz

i meant 850x2

Would you choose any other DDR3 board if you could ?

[-thc-(cZ)]

FYI, the south bridge is ICH9 and not ICH9R = NO Intel RAID on this board. It has a additional RAID chip, BUT you have to have one HDD hooked up to an internal port and the second HDD to the EXTERNAL SATA port!

definitely

have a look at my DDR3 corsair thread i did some testing

i don't know about u fellas but i took some photos of the phase coil that burnt my finger idling....sitting next to the 4-pin connector

i would definitely not buy this board unless i have a sample

and also my one droops bad >>>>>>>>> 1.36 in bios, 1.336 idle windows and under prime it keeps dropping to 1.31/1.29/1.27/1.26/1.25/1.24 i gave it a couple of strokes where pencil mod is supposed to be NOTHING

at first i thought it was my quad core in there so i replaced with dual core and still the same

honestly asus has really disappointed me over the past 6 months or so, it just might be my opnion and i respect everyone elses too, their highend boards are really nice looking and feature rich, but i have had issues with them they seem to have lost focus on initial bios releases, they have the most bios updates out of any manufacturer, and their low end board are really easy to work with and like stated above, the vdrops are horrible, hopefully they can win me back with x38, so far i am happy with abit right now, i really have this habit of not buying the same chipset based board again from one company if it has given me issues the first time, like the asus p35-delux version, i tried two board i had weird bios issues, post not post, oc fine and than it would loose settings, and sometimes it wont apply my oc settings, no matter what i tried. the settings will be set in bios but it wont just apply my settings.

[dinos22]

i tested all the boards you talk about and i must say from my experience asus P5K vanilla, blitz and all 8-phase P5K boards have been nothing sort of amazing especially with first release bios

abit i also tested and was disappointed and sold it off a few days later....my 625Mhz stock speed RAM(DDR2 PC10000 corsairs) RAM maxed out 580MHz no matter what timings >>> the board droop was pretty bad and some funky going on with it...it was just all round and very disappointing........honestly that board is not even close to asus range (except this P5K3 lol hahah) but P5K3 is a ddr3/ddr2 board so some of the bios issues are understandable

vdroop and that hot coil is what really worries me about the P5KC >>> for some reason droop pencil mod didn't work but P5K vanilla did lol

Hi there!

Thanks for you review and every piece of information you submitted. As I am going to be a owner of a P5KC aswell, I am particularly interested in the story concerning the vdroop.

So here are my questions:

1. How do you read the vCore? Which program is the best to use?

2. Where are the measure points on the mainboard in case I get a semi-professional measuring tool and want to read the vCore directly?

3. in #20 you talked about a pencil mod. Unfortunately I am unable to get how this mod needs to be done exactly. Which pencil am I supposed to use? What must I take care of? I think of things like the width of the line to draw or the type of pencil. Would liquid silver be an appropriate solution?

4. Did you state a link between the power supply and the vdroop?


Thanks for your help and sorry for my english, I am german

anybody having ethernet problems? after 370 fsb i get ethernet problem, it no longer works untill i bring down fsb.

I had major ethernet problems and RMA'd. Read through the newegg product reviews half of them returned their P5KC(including me) because of bad NICs.

And then to top off the bad NIC controller, no Fing Intel RAID, and this other esata raid stuff is BS.

The vcore droop measure with my DMM was horrid, like .09v at 400FSB.

GIGABYTE GA-P35C-DS3R is such a better choice. Mine will be here tuesday. The P35C has 6 Intel Matrix Raid ports, supports ata raid, esata. Has a Realtec nic controller which has no issues.

Moral of the story the P5KC sucks. Ruined my entire week trying to get that nic card working finally I RMAed it for a complete refund. Can't wait until my GA-P35C-DS3R arrives on tuesday.....

I have been a staunch fan on Asus boards but the P5KC REALLY upset me. The last Gigabyte board I used was the DS3 965 and it was a great board.

[johnsally]

does newegg give full refunds? I thought they charge 15% restocking fee?

[Eldonko]

I have a p5Kc sitting here now, will post my results when I get a min. Still trying to figure out the vmods tho. :/

[Brother Esau]

the carpet maybe?

LOL

I'm done with the vdroop and vcore mods, and working fine, will update soon..
and the pics from the capacitor explosion in my P5KC
Today I've repaired it (thx the advices to NewBeetle), and works again fine

I'd like to see those pics!

[Achill3uS]

I'd like to see those pics!

here is the history andy
(sorry pics by phone, cam is not at home)

I've tested my QX6700 CPU on aircooling with P95 smallFFT @ 3.6GHz 1.46v and after 15 minutes I heard a big booom, and big smell, like something was burned.. and after I've seen the "result".. so if you are Quad user, the fets and those capacitors next to the socket must have cooled with a fan, doesn't matter aircooling or extreme!







and replaced with "non solid" 16v 1000uf model, what NewBeetle used too





and for P5KC users some vmods (tested, working fine)

[andyOCZ]

Very interesting. Just the capacitor blew up and nothing else? Did you replace it with the same capacitor type?

Thanks for posting the pics.

[35712]

Hey Achill3us! Thanks for your posts. They are really helpful.

Can you tell exactly why the capacitor exploded? Was it because of its heat? What about those who decided to cool their board with water and who do not have much ventilation inside of their cases? Are they supposed to install a watercooler on these components aswell? If yes, could you please show them again on a better image?

Edit: Some more questions:

- How does to the vdroop-mod exactly? Do I have to use a special pencil? What do I have to consider?
- What does the vCore-mod do in particular? Enable higher VCores than before?

[shteer]

nice work!

Welcome
Yep, just that capacitor.
No, the original cap was solid, and I was asking to NewBeetle what typ he used on his P5K-E, I've buyed the same, and it works us fine I think its a bit stronger, and blow up temp is higher too. --> here it is

hmm, I think you should read a bit after vmodding and overclocking, its hard to explain (for me) If you solder variable resistors to the correct points on the motherboard, you could set higher voltage manually what in the bios adjustable is. I think in my event, the capacitor exploded because of the heat what a Quad Core CPU made at 100% load with the board. Yep if you are watercooler user its hard to cooled this parts down, you need to buy special water blocks.. ect, but its not impossible, just time. But, dont forget, if you are home user, dont overclocks your cpu, the heat are more less on these parts!
sorry, I cant make better pics right now.

[Achill3uS]

thank you my friend

[Eldonko]

Thanks for sharing the vdroop and vcore mods Achill3uS, Ive been trying to figure those out. I added your mods to my photo so its a lil more clear.



Do you know vdimm or mch?

[35712]

What do you mean by 50K VR? I've to admin that I am a noob when it comes to this sort of mods. All I've done so far was painting a line with conducting silver in order to get some more bios options on my old Bad Axe.

As I am going to own this board, I am really interested in the vdroop-mod. Especially as I am planning to do some overclocking which would surely be easier without the droop.

Any ideas how to teach me this lesson?

For you, best is to pencil mod. just "colour" the resistor indicated from end-to-end with a 2B pencil.
