You can bet that at least the Compusa stuff probably performs rotten but people buy it thinking that it is a decent silver based iterface material.
Maybe, JUST MAYBE its called silver because IT LOOKS LIKE IT IS SILVER AND ACTUALLY ISNT SILVER? If I buy a car named The jet and its in maroon, you think its gonna be a jet/maroon? Cmon guys.
You obviously didn't read the entire article. OCZ claims their product is 70% silver (99.9% micronized). And of course, it's 0.

Exactly. I used AS-III and had no major complaints. I also used the CompUSA goop and you know what??? I use the CompUSA goop now. It goes on easier IMO and I have 2 XP1800's that have never hit 40C yet, as reported by the BIOS and MBM on ASUS and Shuttle boards, after days of running SETI. I also used the old "feel it" test and neither were anywhere near warm. I use the CUSA goop on my XP2400 and it hits 41C after a couple of hours of hard use. Their results are interesting but It could be made from snot and I probably wouldn't care as long as it delivered decent and sustained results. So far the CUSA goop is holding up pretty well. Not sure how it would hold up after more than a year because I can't remember the last time I actually kept a CPU or HS for that long.
Except that, according to the article, the product is advertised as "Made with 99.9% pure micronized silver, Over 70% silver content by weight"
Just one caution, it is entirely possible that other ingredients in the compound interfere with the solution (this solution looks like a standard precious metal testing solution based on nitric acid and potassium dichromate - before anyone trys to repeat this, do bear in mind that these chemicals are highly corrosive, and carcinogenic respectively.
mrgoblin, it's pretty farking obvious they do it to try and create the impression there is actually silver included in the ingredients of the product. Nobody, nobody gives a toss what it looks like.
Unless... would you like to buy this bar of gold-painted lead? Bargain $10,000 gold bar.

Excellent points, Although this article was conducted using a topical test, it should be noted that OCZ Ultra II Silver Premium Compound, and Compusa's Silver Grease was also sent to a Laboratory to validate my results which will be in a Part 2 Article. The Lab report was done with spectroscopy testing (XPS) combined with Elliptical X-Ray Spot testing with 'burn off'.
OCZ Ultra II Silver Thermal Compound and Compusa's Silver Paste are composed of Aluminum Oxide in a Polymeric binder of dimethyl Siloxane (silicone) and it contains an organic Silver coloring to give it a silver 'appearance'. The lab report also states that OCZ Ultra II Premium Silver compound AND Compusa's silver grease were most likely made by the same manufacturer and their chemical makeup was the same . That I found interesting
But OCZ has contacted me and they seem genuinely concerned and are investigating this with their own independent lab testing. We will see if their results concur with my lab results.
So very soon I will release part 2 and we will see where we are at that point.

Mod please delete this redundant reply -thx
Been a long day for me, had to reply to several hundred emails and many many threads (Today I found out how big the internet is)

Yes I expect to see a valid test. Break out the gas chromatographer.
EDIT REPLY TO ABOVE. Just read that. Are these results available?
There is very good chance a vehicle is present that is preventing the simple litmus test from showing a positive.
That aside, thermal transfer tests are more important. Even more important (at least for OEM installs) is stability over the long term. AMD for example, discredits the use of any grease compound and strongly recommends a pad.
Many tests show that Arctic Alumina is *the* best compound that's publicly available. Does it even have Ag?
Cheers!

My tests were solely to determine if silver was or wasn't present. The part 2 article will be run probably tomorrow or Fri.
No wonder this OCZ stuff was so cheap. I got 2 tubes of OCZ for the price of 1 AS5. Reading another review, OCZ also performed poorly.
But I read other reviews before and the stuff beat AS3. There's conflicting reviews... sigh.

The fact remains that I have lab report that despite the wide variety if chemicals that compose thermal grease, clearly shows a Zero percent Silver(Ag) presence. The lab burned off the chemicals and it underwent spectroscopy testing (XPS) combined with Elliptical X-Ray Spot testing with 'burn off'.
All I can tell you is that the supplier is not using Silver in the Compusa Silver Grease and OCZ Ultra II Premium Silver Compound. Hey at least OCZ is looking for the answers, I would have liked to have seen Compusa's or OCZ's MSDS regrding these products or one of their old Lab reports, soon we will knowon OCZ's end anyway what the heck is going on in them thar tubes.

OCZ would like to take this time to address the recent article published at Overclockers.com, which shows that OCZ Ultra 2 thermal compound has no silver content.
OCZ does not manufacture Ultra 2 thermal compound in house, it is provided by a foreign manufacturer with our specifications. Previous independent lab tests conducted at the request of OCZ have shown that the silver compound content in Ultra 2 is 25% by volume and 70% by weight.
In response to this article, OCZ has submitted another batch of Ultra 2 to a third party for extensive lab testing. This Independent lab report show?s that the most recent batch of OCZ Ultra 2 indeed contains less than 1% silver by volume. While simultaneously we have received lab reports from an outside source indicating the silver content to be 30% by weight. This leads us to the conclusion that recent batch(s) of OCZ Ultra 2 from our supplier did not meet the agreed specifications.
We accept full responsibility for these problems and we will be seeking legal action against our supplier.
In order to help solve this problem we have contacted Arctic Silver Inc, and entered into a vendor agreement with them to supply OCZ thermal paste.
Beginning January 22nd 2004 we are issuing a full recall of any and all OCZ Ultra 2.
Any Customers who wish to return OCZ Ultra 2 thermal paste with an invoice will in exchange for their full or partially used tube(s) receive:
1- One (dependant on # of tubes returned) 3-gram OCZ thermal Compound (made by Arctic Silver Inc.) or one OCZ Dominator 2 Heatsink.
2- One OCZ EL DDR T-Shirt
3- One 10 dollar off rebate on any OCZ EL DDR Dual Channel Kit (at participating resellers)
For more Information or instructions on returning your ultra 2 please email recall@ocztechnology.com
I would like to commend OCZ for investigating this once I brought it to their attention and commend OCZ's quick action. I truly was shocked to discover the absence of Silver and I am truly grateful for OCZ's Owner and Staff to quickly find a remedy.
I will write an article or an editorial to praise OCZ's actions shortly. OCZ did not turn a blind eye to this situation like Compusa has, and continues to do.

Well atleast they were quick and efficient about it.
One could think of many reasons why OCZ would be so quick to solve the problem. Not all of which may concern customer satisfaction.
Oh well, tis better in the end.

To be honest I did not think OCZ would act so quickly, but I am extremely pleased OCZ rectified this in short order. Compusa is still in my crosshairs and I do not give up easily, anyone that knows me knows this.
I am absolutly amazed at OCZ's response because at one time they were a terrible vendor that sold junk and would not stand behind the product. I am going to mail them a letter to tell them my feelings and would recommend this co to anyone.

Personally, I'm enormously surprised to see OCZ caught making false advertising claims... NOT. And look at all of you suckers, falling for their show of righteous indignation towards their supplier... where's the typical Internet-dweller's sense of cynicism? Eh?
