I know dielectric grease works that way. More specifically I was talking about AS Ceramique. I have never put any into a MB socket to test. (I have done some sub-ambient cooling so I know dielectric grease is good stuff.) I have heard of people using thermal paste as a substitute for dielectric grease. It was more of a specific thought to Ceramique used that way. (Obviously AS5 would not be so good used that way. ;) )

EDIT: I have not personally ever used Ceramique or any other thermal paste other than how it was intended so this is more of a question..... could it be possible?

Sucks you have had this trouble.....nothing worst than having hardware die.

As was said before.....pretty cool pics.

Yup, I know you really liked that 4800+ of yours :( I'm telling you though, that 4600+ I got you isn't exactly what I'd consider an "average" oc'r ;) As the younger brother of OPB's god-like 4600+ (R.I.P.) your 4600+ ran a good 3-4C cooler than his @ the same Vcore. Although the memory controller wasn't quite as strong, it still is one of the better ones I've ever seen on ANY x2. A little OT, but did you notice a cold-bug with that cpu + ln2? Also, are you still planning to send it off to OPB for a few runs @ PCMark? I'm glad to hear the cpu is still up and running. OPB tortured his 4600+ and it handled everything like a champ - until meeting one very screwed up socket :p:

hey mikeguava and dumo,

here it is.

with 3dmark05 we got 97** max atm.


tomorrow benching 780 with ln² with teammembers:D

Dude!! You showed the Q-TIPS!! That is the biggest overclockers secret....now everyone will know how to get awsome scores. :rofl:

try to mount an SP90 on a 7800GTX takes skillz, no everyone can do that.

We play open cards;)

hint: di-electric grease in place of thermal paste ;)

If the board fails to post (4 LED's lit), the pre-CPU detection voltage is given to the CPU.

If you have a low Vcore and high % increase set, I would hate to imagine the sort of voltages being given to the CPU :eek: (about 2.15v worst case from what I worked out)

Thats the bug in the 704 bios for the NF4 series. However, my brother just noticed something on his DFI CF-DR. at auto, his volts were spot on for his x2. MANUALLY set to 1.3V no multi thing, just trying to get it a little cooler, smart guardian read 1.55V - the whole time.

Personally, i think its a bios issue again with regards to Vcore and newer CPU types (fx57 and X2's seem the bad cores)

My brother was on the stock (shipping) bios: any bad luck with the new official beta?

The offical beta has been tons better than the shipping bios for me.

I have a 3800+ venice core i overclocked it to 2.8 ghz one day a wire blocked my heatsink fan and while i was playing quake 4. The pc just shut off so i turned it back on and went into the bios my cpu temp was 95c LOLahhaha. Still works fine you must of done something really bad to cause that. Hell i even overvolted my processor 1.7 vcore and the pc just shut off. I pressed the start button and it turned on normal.

Ummm...mike's not exactly a noob - I think he would know if he installed a cpu and bent some pins in the process.....

it could have got bent in the shipping, on the way to the RMA people. and i cant quite remember if this was the thread or not, if it was, he said earlier that after it died he just tossed it around a lot, even left it on the couch: damage ahoy.

New beta bios at last :) http://www.dfi.com.tw/Support/Downlo...FLAG=B&SITE=US

Cool...lets see how this one goes :)

I got finally my X1800XT and put all togother... and I have serious troubles with this mobo. It wont be stable if oc even little bit (FSB 210). Kind of common warning message is: "MS Windows has detected and recovered from device failure. Save your works..." And resolution before this message is dropped to 640x480. I think it's some how related to GPU card.

Edit: forgot to mention that this error-message come i.e. in 3Dmark when testing CPU.

this reviewer at vr-zone says the pci bus is not locked on the RDX200 http://www.vr-zone.com/index.php?i=2893&s=14

I think this is true as my pci adsl modem can't connect when i overclock to much :/

got to try this latest bios i reckon

Here is one thing that needs to be know? Is the Vdimm feeding both ram and memory controler? If yes then when upping the Vdimm you are upping the voltage beeing feed to the memory controler.

Is there a way to read the voltage to the memory controler to see if this is the case?

It's not the case.

And if it is/isnt?
Are you going to tell DFI/ATi how to design a m/b?

New beta bios has a bug and it doesn't show up the Sil3114 raid bios ... :confused:

But ... the fixed the problem with the 4 leds when you enable usb keyb/mouse support .

say, with the eating cpu problem, is it just a select few motherboards, or 1/4 or 1/2 of the mobo's, and is there any way of finding out weather you have a hungry motherboard or not? i was hoping to get this motherboard, but i only work during christmas and spend all my monies on a pc...
and ited be kinda crap to keep on RMA'ing cpu's every 10 - 20 min that i get it...

Not every RDX200-CF DR is causing this.
I have been running with voltage avg. of 1.66-1.772 on
an fx 55 CH and the cpu its still very much alive.
Don't be scared, if you plan on going CrossFire or want ati chipset board
the RDX200 is best choice for what is currently available for CF boards. :cool:

I got the 2nd CPU back from DFI along with 2 new boards. The CPU still works like a charm!



Board #1 burn out could certainly have been caused by an earlier dry ice run - if the board got messed up without having an intitial damage, which then slowly but surely went further and then eventually killed the cpus. I have run NF4 lanparty boards full of condensation for 24hours for an extreme abuse test and didn't get any problems - this could have just been the one time it did have an impact.

The thing what made me doubt things is that all those deaths were caused during air runs.

Board #2 still is a real mystery to me - especially with the voltage rise that I had seen. I know for SURE that the cpu was clean - but that's all yesterdays news...

I do not know why the second board had the burn marks on the pin socket - I had actually taken both sockets apart and the "burn" were MORE appearent form below the socket. I suspect something wasn't perfect with that board - but didn't cause any damage to any hardware - and if only to itself :-)

DFI had sent me 2 new boards ( I told them to just send me the broken ones - since I had killed 'em...) and eventually I will fire them up again. But no gems will go in for now...but the both should be working great as they had been tested for a while by DFI

THIS IS EXCATELY WHAT I WAS REFERRING TO! BEING A POTENTIAL X2 KILLER

This is what happend to me with board #1 as well as with board #2

I hadn't followed this thread and just saw this. Now I am getting more suspicious again. I still have a brand new untouched RDX board from my first batch and will look for that again when I find the time.

One thing is sure - once all the bios bugs are sorted out - this will be a GREAT board!

Just came to my mind, that maybe my power is too insufficient for this set up? So what kind of powers you guys have? I mean u who have this mobo working fine.

i have a rdx with a 500W psu and its working fine now:)

UPDATE: I finally started up one of the new boards. Within 30mins I managed to get TWICE the same problem - where I get a huge boost in voltage.

There is no doubt in my mind that my X2 went due to the voltage jump that the boards can induce.
Things are becoming much clearer now. I had the voltage set to 1.4V and 104.8% and got 1.6V out (- ouch) and once 1.4V and 102.X% resulted in 1.56V.

The way this happens I am pretty sure is when you switch CPUs - the bios gets stuck in the start-up value ( 1.55V) and adds whatever % you have added. X2 4800 RIP! I will have to confirm that later - to find a sure way to reproduce this problem.

the board this happend was one from DFI directly and on bios 10/11. The boaord is REV3 and has none of the biosreboot problem ( which is nice!)
