Also, how did you get 6,434 marks on only 4.01Ghz? Thats quite an accojmplishment, I managed 6,525 cpu marks running 4.25Ghz with DDR3 linked @ 1700mhz cas 9. Oddly enough, my cpu physics score was 437. Interesting lol

I guess i just got a pretty good run. the physics however were not up to snuff at all. It seems both of the C0's are run into the ground or just aren't that strong physics score wise. the most i could muster i believe was in the 350s and that was the same run that netted me 6,434 marks. I'd have to guess your physics score is all the ddr3. We aren't talking about physics only though, its all cpu mark #s im sure if someone ended up with a better binned chip/later revision they'd have better physics scores.

I was just impressed that my junky C0s actually show up. Albeit needing A LOT of voltage, they still can put up the #s fairly well even with the ddr2. I just wish i could acquire a 790i board to bench these chips with. I just want to confirm it actually is the ddr2>ddr3 difference, which i am about 95% positive it is.

You've run both though, how did your E0 5470 fair on the ddr2 physics wise? didn't you say your chip jumped like 40-50 points earlier in this thread just from moving from ddr2 >>> ddr3???

I personally am not even out for the highest benches ill be more than happy with my meager almost 6500 score and 350 physics score. This mod really works for what I was trying to do and now that it's done, I think its time for me to move on.

As far as I know AS5 Is not really electrically conductive, it seems to be a myth spread out on the net. I tried measuring a glob of it with ohm meter and did not get a significant reading.
But does not matter as I apply it carefully in small quantity without doing a mess.


No harm intended, but simply put AS5 has micronized silver particles in it's composition. Silver is in fact more electrically conductive than copper, but cost prohibits it's use in normal applications.

According to their website it is only capacitive and they heed warning to it's capacitive nature. My common sense tells me that given it's composition of an electrically conductive material (silver) and in the right circumstances it could potentially fry a component...then there is no reason for me to risk using it.

Let me ask you this...had you spilled even a tiny bit on a resistor say somewhere near your cpu socket...do you think you would be able to remove every tiny particle of silver? You just now have created an electrical bridge even if on a somewhat micrscopic level.

Not to mention the warmer the conditions the greater potential for electrical conductivity. Anywho, I respect your choice to use it, I just wanted you to be aware of the risk smile.gif

Ok got my p35 platinum board in, modded it, threw in my x5460 and it posts but freezes after checking the memory. Possible out of dat bios? It recognizes it as a xeon too. My e8400 boots up fine.

n1sm, in a way you are correct. The DDR3 has attributed to my higher scores, but only in a sense that it gives the CPU it's information faster. It releases the bottleneck that you get with DDR2. The processor is still processing the instructions and information only it's not waiting as long for the RAM to fetch it.

Can someone add the microcode for an E5405 and a X5460 to this BIOS? I am getting an E5405 free and if I need more performance I would like the option to upgrade. This is going to be on a P5B Deluxe so I will post results after I give it a try.

The Letter in the batch code has nothing to do with stepping. Both my X5460 & X5470 have "B' batch codes but are identified as "A" in both CPU-Z and Intel CPU ID utility. I have the read official documentation on the batch code which tells you how to get the manufacture date and assembly location, nothing more. There is nothing official on the letters "A", "B", "C" or proceeding numbers. All I have read on multiple forums is speculation based on information a few users put together on a few CPU's. This is just misinformation that has been passed along because there is nothing official to disprove it. It goes right along with the phrase "I read it on the internet so it must be true" Until I see something official from Intel, I am going to say this is nothing more than a sequential batch number, IE A998, A999, B001 etc. This is why "C" is so rare.

His voltage is fine, I run at 1.375 450 FSB X 9. That's Intel's max recommended voltage. Running it lower may cause stability issues.

Look for 000000's post a bit earlier and check his signature for a guide.

And, it does. Stability is not there @ 1.325 like I originally thought. If you cannot marathon a cpu on blend test at least 8-12hrs I feel it isn't stable for gaming. Most believe its 6hrs but I've had issues with my q8200 when it was overclocked on the same 780i after having it solid for 6hrs. I was getting crashes in bf3 and sound locks ect. Since I've gone to p95'ing my cpus 8-12hrs prior to stamp of approval, I've had no issues.

Still can't believe I finally finished off my gigabyte ep45 though. It wont even boot up now :-p. That isn't abnormal though, if I shift the ram in the slots then it should boot back up. But this board has been on the verge of a total meltdown from when I got it 3yrs ago. I guess I should stay away from Gigabyte boards, I've read that the ud3l had the infinite boot loop and I've experienced it a few times.

At any rate, as soon as I get new thermal paste in i'll lap the cpu on my 780i and i'll clock up to 4.3 or higher and let her hang out in that neighborhood IF I can keep my physics score in the mid 300s.

Still struggling with this.

Conductive and Capacitive, despite related, are not the same thing. What they mean is that the compound has a dielectric value that his higher than air. Like the dielectric fluid in a capacitor, if the compound is applied between two conductive parts, the ensemble might act as a capacitor. But this would likely not be an issue at all unless the two parts are very close to each other, because the total capacitance will grow exponentially with the proximity of the two parts.

So I might get worried say if it got on the pins of one of those Very small pitch SMD chips, where you can barely see the chip legs with your naked eye, those are very close from each other. But even then I do not think it would result in immediate damage, the way a conductive paste would, but rather improper operation.
I have seen some botched Xbox 360 repairs where people had put AS5 all over the place and the console still worked.

I think part of the running conception of arctic silver being dangerous comes from their older product, Arctic silver 3, which was indeed conductive and indeed fried people's hardware all over the place.
Not saying you do not need to be careful with AS5 mind you. Just saying its really not likely to insta-fry your stuff if you spill it. Might cause problems only if you are unlucky and it get the stuff at the total wrong place.

I do use it carefully and dont put it all over the place. I have steady hands and am used to working in electronics. I repair and mod lots of old consoles.

But thanks for your recommendations, I will check those alternative compound. Will likely try something new when Im done with the AS5 tube.
