okay.. sorry that dont waste my time to photoshop or I havent a photo studio :mad:

[michaLcoughliN]

he means. Carpet = Static electricity. meaning. Suicide for electronics

[Bail_w]

What a way to handle computer components lol, anyway good results maybe you should test your p5k vanilla.

[Achill3uS]

I allways put things on it, I report you guys if my woolen carpet kills them :ROTF:
OMG, everybody is going to crazy, its too hot? :D:hitself:

[eklipze]

mmhm.. crazy hahah!. i want to see some comparison on the 2 boards. hopefully. thanks. like to know

[Solarfall]

i would like to see 3dmark scores, if thats not too much trouble :D

btw does anyone know what does the C stand for in the product name.

[jugeen]

here is really hot, but never mind being crazy till you don't insert your CPU upside-down :rofl:

[RPGWiZaRD]

btw does anyone know what does the C stand for in the product name.

"Combo" as in MSI P35 Neo Combo or Gigabyte GA-P35C-DS3R which all come with both DDR2 and DDR3 slots. I'm gonna pick either the Gigabyte or ASUS one myself, just dunno which but if this ASUS one really does max out at similiar FSBs as P35C-DS3R (usually just above 500 FSB) then I'd rather pick ASUS due to the extra features I'd get, firewire and eSATA support and more USB ports and also ASUS lets you manually specify frequency for memory vs Gigabyte still uses dividers (if I understood that right). So 520 FSB was max you were able to reach with this chip?

[Solarfall]

@RPGWiZaRD ah of course.. :doh: how could i not remember that.. well thanks for the info. :up:

[over@locker886]

Sorry , I have very bad news:(

My teammate mobo's maybe randomly died.:shrug: He is very sad,because mobo one day old, and he waited for mobo 2 weeks.:( If mobo will works, he will post new results, or he will send back RMA.

[LogAn'sRun]

the carpet maybe?

[over@locker886]

the carpet maybe?

LOL..NO. We never bench on carpet, only he made photos...

Not surely mobo died yet. maybe vga.

[OBR]

Looks like good DDR2+DDR3 mobo ... but show us DDR2 and DDR3 scores, on some boards with DDR2+3 slots ive tested (MSI, Giga) was mem performance very low ...

[K.I.T.T.]

I'm assuming this board doesn't have vCore damper built into the BIOS?

Seems a nice board for the price :)

[TyphooN]

Achill3uS, I have a P5K in the mail, since you have both boards.. Should I return it for the P5KC? I was planning to do the vdroop mod on the P5K but you say that the P5KC doesn't really have a vdroop problem, which is my main interest.. Other than that, does this board perform better in any way?

[Aivas47a]

Looks like good DDR2+DDR3 mobo ... but show us DDR2 and DDR3 scores, on some boards with DDR2+3 slots ive tested (MSI, Giga) was mem performance very low ...

I've been wondering whether memory performance on the combo boards would suffer vs. boards designed for one type of memory (ddr2 or ddr3). Some comparison tests on that issue would be most excellent! :D

[Achill3uS]

I'm back :) my vga card died in this crazy hot (in my city 41°C outside :eek: )
So testing continue.. tomorrow I will do a compare test with my friend's Corsair 1333 DDR3 :D
The P5K I used to 2 month, as I tested this board is no way slower!
And about vdroop, at higher voltages, is not so little as I write, around ~0.05v, with damper enabled or disabled.

[Achill3uS]

some bad news :( the mobo (with latest bios) dont working with Corsair DDR3 1333DHX memo's, I could go to bios, but 1333 even as 1066 CL9 dont give signal.. (the max vddr was 1.7v what I tryd) :shakes:

but I think this would be useful :up:

http://img504.imageshack.us/img504/9108/vdroopnc9.jpg

[Electricview]

My question is, does the p5kc in fact not have the memory speed boost feature that asus boasts for the p5k on their website? (it doesnt mention it for the p5kc which is why i ask... i was considereing these 2 boards but when i compared every stat on asus's website it seemed like the p5k was edging out the p5kc in a lot of things except ddr3 support.

[Jasy]

Can you test this mobo with DDR2?

[ginnz]

LOL..NO. We never bench on carpet, only he made photos...

Not surely mobo died yet. maybe vga.

dude.

it has nothing to do with benching on the carpet, or photos on the carpet. what were getting at is putting a MB on the carpet MAY CAUSE DAMAGE due to static electricity. comprende?:confused:

[Devious]

i want to know if the voltage damper works on this model.

[jeffyjaixx]

Nice.

Did you have to update the bios or did it ship with bios 0701?

[Fr3ak]

I am testing this board right now. Voltage damper exists in the bios, but does not work at all. Same vdroop with it being enabled and disabled.

Vdroop is driving me crazy. 1.4875V set in bios results in 1.448V idle and 1.4V under load...

It seems to clock DDR2 quite good, but I haven't tested these GMH in another board, so I cannot compare their performance.

I can boot into Windows and run 32M with 450MHz, but 32M stable is just 420MHz, no matter what FSB or chipset voltage I set. 420 seems to be rockstable with all voltages to the lowest possible.

I am using a E6750ES for the record.

I am not allowed to do any mods on the board, so I cannot vdroop-mod the board :/

If I have the time, I will make some DDR3 tests when I am done with DDR2.

I just bought this board as well... vdroop is high as well. 1.60 in bios and 1.50 idle and 1.4 load. Is it my psu?

Thanks Fr3ak! I'll wait for your next tests ;)

I am not allowed to do any mod on this board, it's not my own board.

[Achill3uS]

i want to know if the voltage damper works on this model.

dont works, like in P5K "V" :mad:

Fr3ak:
could you test the mobo with DDR3?
and one more thing with DDR2, in the yellow slots except the 1:1 dont works fine the other memory settings, hell stable clocks like 1000cl4 dont give me signal after saving.. only on the black slots..
this is the only problem what I've find, maybe later will be corrected..

upper was question with Quad CPU's, yes they overclocks fine..

[Fr3ak]

The yellow slots seem to work fine for me, but I will trythe black ones to see if it makes any difference. I am using a X6800 retail now to test max FSB of the board, but it seems to OC worse with that CPU then it did with the E6750ES . . .
I thought the CPU was limiting with the E6750 as just 1 core failed and I could not get it stable above 420MHz FSB no matter what voltage settings of the board I used. 420 runs with everything at lowest values.

What bios are you using btw? I am using the stock bios that came with the board, which is 0502.

[bichi]

Achill3uS,

Can you do me a favor and tell me what the part number of the BIOS chip is?
- or take a closup of that part?

Thanks!

[Fr3ak]

Fr3ak,

It says:
25X80VAIZ
0714

:)

[Jasy]

bichi, why do you want to know that?

[Fr3ak]

btw the 701 bios looks like a winner. With the old 502, I could not clock the X6800 higher than 400MHz FSB (dual 32M stable that is). Now 430MHz FSB has just passed, so there is even room for more.

I will do some DDR3 tests, most likely tomorrow. But no heavy OC stuff, just some tests to see if it works ok with the board.

[bichi]

It says:
25X80VAIZ

Many Thanks, Fr3ak!


bichi, why do you want to know that?

Jasy,
- appears some P5K series boards have BIOS chips soldered to board (might be a cost saving trend for future boards)
- part number verifies it's in Winbond's 25X80 serial flash family (8-Pin PDIP (socketed) and the SOIC 208mil (surface mount, soldered)
- if I do decide on a PK5 board with soldered BIOS chip, I know which part to have as backup, in case I pooch a BIOS flash
- (only pooched one BIOS flash in 20yrs, but when it did happen, it was at the absolute wrong time...)

[Fr3ak]

OK I have to admit that he board is not as bad as I originally thought. Surprisingly the vdroop is not as heavy as it seems. The readings of CPU-Z and Asus Probe 2 are lower than what the actual voltage is.
For example:
1.5250V set in bios
1.440V according to the bios hardware monitor
1.408-1.424V CPU-Z load, CPU-Z reads the wrong voltage when idling
1,46V Asus Probe 2 idle
1.42V Asus Probe 2 load
1.487-1.488V idle measured
1.460-1.470V load measured

Too bad I am not allowed to do the pencil mod right now. I bet it would help a lot. But then again the question is why Asus doesnt replace that single resistor. I bet its worth less then a cent. . .

[Jasy]

They don't do it because people instead of buying deluxes(etc.) would buy this one... Not a board for enthusiasts (by now).

If you could do the mod...

try to do the pencil mod, for me it helps much, vdroop is more than bios set :D 1.40 is real 1.41-1.42v

and yes, I'm using 0701 too.

I'm waiting for your DDR3 tests how your mobo like's them.. "May the Force Be With You" :D

[Jasy]

Can you oc it with all the vmods to see the maximum fsb?
When you post ddr3 scores, post ddr2 too. Please :)

[Liquid3D]

What's the best DDR3 overcklock? I've been on the fence and have an order waiting for a X3210 and a P5KC from my friends the Nooks up North, great prices but then they pull the Canadian "Hat trick" on your arse.

1.) Shipping prices all of which add a minumim of $23 ~ $37

2.) must buy insurance $5.50 ~ $11

3.) Even with $37.50 FedEx Priority Air it's five ~ seven days.

Total $410 for X3210 (which might not even work in the board, 775 platform or not) and P5KC for me that's no eat this month and pay half cable bill (I'm disabled and I can add Menatl Disability if I do this)

EDIT: should have got it instead of the Slacker Q6600

[Achill3uS]

Can you oc it with all the vmods to see the maximum fsb?
When you post ddr3 scores, post ddr2 too. Please :)

the vmod points are not the same as P5K Vanilla or Deluxe, I've find the vdroop & vdimm mods, vcore and vmch still not, but if you are not extreme overclocker you dont need them, I post one result from my maxfsb, easy 530 for the mobo, but the cpu has there fsb wall. Today the P35 boards max fsb is usually more than your cpu.
btw what ddr2 test you want to see? :)

[Jasy]

That's a good fsb :)
I just want to know the max you can get with the ddr2 and some superpi 1M/32M.
Comparing this board with the p5k wich one is the best?

edit: When you find all the vmod/reading points, post some images.
Thanks ;)

[dinos22]

i have this board for testing along with corsair PC10000 DDR2 and Corsair 1600MHz CAS7 DDR3 sticks

i've had some quick tests with DDR3 and pushed it to ~850 but seems there is a frequency limit of some sort as it was around 2v with CAS7/8/9

will do a pencil mod as droop reported in CPUz is bad and my E6700 has trouble booting at 4GHz which it should not

will do some decent tests and post some results in a new thread to avoid clutter here :up:

[Liquid3D]

Can't thank you enough for that update, you may hve just saved me many hours of headaches and the money which I don't have to spen on the board.

This is what DIY community should be all about. Of course I do hope your able to correct the problem.

[coldpower27]

Are there any undervolting options for the CPU voltage on this board, this looks like the perfect board for me, and since this is P5K standard with DDR3 support is this 4 phase Power?

[Eldonko]

the vmod points are not the same as P5K Vanilla or Deluxe, I've find the vdroop & vdimm mods, vcore and vmch still not.The vmods aren’t the same as vanilla? Do you have some vmod pics to share plz?

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!

[dinos22]

Would you choose any other DDR3 board if you could ?

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 :( :shrug: unless i have a :banana::banana::banana::banana: 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 :eek: 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 :down: >>> the board droop was pretty bad and some funky :banana::banana::banana::banana: going on with it...it was just :banana::banana::banana::banana: 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 :D

[35712]

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&#37; restocking fee?

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!

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?

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 (http://homepage2.nifty.com/NewBeetle/original_replaced.jpg)

hmm, I think you should read a bit after vmodding and overclocking, its hard to explain (for me) :D 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.

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?

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.

Yes, deja vu..

Tomorrow, I will talk with one person from Asus Hungary and tell these problems.

[Eldonko]

35712, a 50k VR is just a variable resistor with 50k resistance. Basically you solder it between the two points marked and adjust until vdroop is gone. But if you are new at that type of thing it is probably best go with cadaveca'a advice and do the pencil mod.

[Achill3uS]

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

I know the vdimm too just need to test it, vmch I dont need but maybe could show you where could be find.

So I called ASUS today and they tell me that only Kingston DDR2 mem is supported by the board lol. So apparently because my D9GMH is Mushkin and Crucial and not Kingston I'm SOL for support.. They dont even know how to say the different types of chips properly, ie qimonda, elpida and they base their support on manufacturers instead of particular chips. Ridiculous. :mad:

[Eldonko]

Ok so with the help of Brian @ Mushkin and Jimmy @ ASUS we got the divider issue sorted, whoo hoo! :clap: :clap: :clap:

First off, forget using auto on any RAM secondaries when changing DRAM freq. BIOS sets them too tight and you get no boot. So disable DRAM Static Read control and set secondaries as follows:

TWR: 5
TRFC: 42
TWTR: 11
TRRD: 3
TRTP: 5

5:6 and 4:5 dividers now confirmed to be fine! My issue was static read had to be disabled and twr was too tight. Now that I have this thing working properly I can do the mods. :)

EDIT: H20 FSB test, 510, shooting for more sub zero.

Yeah, I know what you mean. Last night I measured those fets with fluke and they hit 75-80C orthos loaded! Tonight I am going to add a 120mm directly over that area, should help a lot. I'm pretty sure that is why your cap exploded, that is the hottest area of the board, right at the base of that cap.

Try 4B or an other pencil not all of them works fine.

sorry :) extreme oc'ing isn't safe, especially with LN2. I've given to more voltage, this mobo has got only 3phase, cant handle so much voltage to a Quadcore CPU :(

but back to your problem, CPUZ didnt correct, its only estimated. if you wont to know the real vcore you need to measure it, with a multimeter where I signed the vcore measure points on the mobo. http://img517.imageshack.us/img517/343/vdrooplb7.jpg

[pak]

Well I keep my multimeter at work. I'll have to bring it home tommorow to be certain on the vcore. Aslong as the vcore stays in check close enough to what I set it at, I am fine. Before the mod, its seemed like the vcore would continue to drop after a few hours of P95.

I currently have my vcore set to 1.4 and it is staying at 1.4 loaded. It booted at 1.392 then moved up again after a few moments in P95. W/e the case I am satisfied. I currently have my quad at 375x9 which I couldn't achieve even at 1.5625 vcore previously.

Has anyone had any bad side affects because of this vdroop mod so far?

Thanks again!

No way, from only vdroop mod I dont think that ever one mobo died :) But dont forget something, the vdroop mod is like the name, its for dissolve vcore drop under load, but bios set voltage not every case will be the same. Like with my P5K mobo. I do the vdroop mod but still it was 0.01-0.02v difference to bios set and real voltage.

does this board have bios options to run ram at ddr3 1600mhz?

[Bradbury]

I can’t wait to try that pencil-mod when I get home from work! I switched my B3 for a G0 yesterday, and tried it at 3.5Ghz with the vCore sat to 1.675v in Bios but it dropped to 1.4 under load. That’s insane! To make things worse, under full load, the multiplier drops to 6 after a minute or two, then it jumps back and forth between 6 and 9. And that is with Speedstep disabled.

[WSX]

sounds like it's not disabled to me.

[Bradbury]

sounds like it's not disabled to me.
Well, it is.

The frequency remains perfectly fine on 3.5Ghz while it's idle, but the multiplier drops after Prime95 has been running for a minute or so. CPU-use is still on 100 % while this is going on, and Prime does not fail.

When the multiplier is at 9, temps are about 68°c and vCore is at 1.400
When the mult drops to 6, temps drop to around 64-65 and vCore jumps to around 1.460

[WSX]

the only thing that I know that would cause a multi to drop to x6 is C1E, is it disabled in bios.

[Bradbury]

the only thing that I know that would cause a multi to drop to x6 is C1E, is it disabled in bios.
Yes it is. But my last post should explain well enough that it isn’t a matter of Speedstep (C1E). If it was, then the multiplier would drop while the CPU was idle, not the other way around.

Edit: Nice, the pencil-mod worked. Only just trying it out now. On 3Ghz with the vCore sat to 1.4v in Bios, it fell to 1.224 before the mod, now it's 1.312. Not perfect, but much better. With the B3 I had before, it was at 1.208.

PM me mate, i could help you, mine was repaired too. but, my advice is to replace the mobo, its weak for quadcore :(

[Eldonko]

Yeah this is true, even with vdroop mod it could not hold load and after about an hour of priming poof. What makes me mad about all of these P5K is the vreg is so crap you either get 0.25v less that you set in bios for load or you droop mod and it blows up because the ic cant handle it.

Cant someone make a board that can hold load without droop or fire? :mad:

After seeing the last two pictures from Donko, I hope that my watercooling block can handle the heat from the vdroop and a 1,45V Quad Core...

Do I need to worry about anything? What settings did you run?

[Eldonko]

That was pretty low volts, I just had vdroop mod done so instead of drooping like hell to save the transistor, it blew. I wouldnt worry about it, just put a fan over that area if you can. :)

[35712]

I have it on water. 22&#176;C - 27&#176;C. Should be enough to survive the 1,5VCore I am currently running for the next 4 1/2 hours. And if not :rofl: :down:

Hi!

This is not an overclocking issue, but I have read about ethernet problems with this mobo here so that's why i am posting here. Maybe you can help..
I have a new asus p5kc and it has a weird ethernet problem. If I try xdcc-ing on irc (http://en.wikipedia.org/wiki/XDCC), the whole connection dies. I mean not only the internet connection (which is through a router), even the LAN is unreachable until I reboot. After that everything is ok again.
I have tried using a PCI card, and it has no troubles with xdcc (and of course i never had problems with it before the new system). I had an older driver for the integrated one, so i've updated it to the latest to see if that solves the problem but it didn't. I use torrent and ftp and a lot of other protocols but none of them seems to kill the connection like xdcc does. Xdcc uses ports from 1024-5000 so i have tried modifing them to see if the problem has anything to do anything with ports, but the result were the same (after like 15 seconds disconnected). A friend of mine has p5kc as well and has no problems with xdcc-ing so not all of the p5kc-s has this problem.

I can return it, but what if I get the new one and it has the same problem? :) So I wanna try everything to solve it before i go for a new one.

Any idea?

[ZorK]

Is the P5K Pro the same with P5K C when it comes to oc-ing quads?Cause I would like to buy one p5k pro and a 8200 and I was thinking that maybe in the feature i would go for a quad

Is there any board with the same price or lower with P5k PRO that is doing well with oc-ing quads?

Or should I try a cheaper mobo and good oc for now with 8200 and when it's time for the quad,get a new and good budget board for the quad(hopping that in the future would born new mobos that would do oc easy quds)

thank you!

but im swearing off asus for this board
may last 3 or 4 years lol

I had an older driver for the integrated one, so i've updated it to the latest to see if that solves the problem but it didn't. I use torrent and ftp and a lot of other protocols but none of them seems to kill the connection like xdcc does. Xdcc uses ports from 1024-5000 so i have tried modifing them to see if the problem has anything to do anything with ports, but the result were the same (after like 15 seconds disconnected). A friend of mine has p5kc as well and has no problems with xdcc-ing so not all of the p5kc-s has this problem.

I can return it, but what if I get the new one and it has the same problem? :) So I wanna try everything to solve it before i go for a new one.

Any idea?


I don't think too it is an o/c pb .

After reading some posts on forums related to this mobo , I definitively point at attansis drivers which looks very buggy .

My ethernet port is recognized under windows but once worked after I plug , then no more .installed drivers several time without success then let it down ! :mad:

Actually using a PCI card and very happy with ( realtek like ) :yepp:

forgot about my attansis gigalan ........

Hi all!

Did anyone figure out, where is the Vdimm measurement point, in this mobo ?

[johnysb]

asus should try making a new stable bios, cause 1001 and 1105 are totally failure.
dont try those two

some bad news :( the mobo (with latest bios) dont working with Corsair DDR3 1333DHX memo's, I could go to bios, but 1333 even as 1066 CL9 dont give signal.. (the max vddr was 1.7v what I tryd) :shakes:

but I think this would be useful :up:

Back to the future....

Has somebody tried the new fast low voltage DDR3 on this MB?

Some of the new Gskill "P67" DDR3 is super fast and has low voltage.
