What thermal compound goes with socket a antlon xp?? HELP!!

hey, i posted before, ive just sold me socket a processor, athlon xp 3000+, i desembled it so i can post it, just as some advice to the buyer when he re-assembles it, what compound should i recommend and how do you clean off the old stuff from the cpu and heatsink???
thanks much appreciated

YES USE COMPOUND
Make sure to remove ALL the old compound from CPU and HS
Clean the HS and CPU die surface thoroughly with alcohol just before installing compound on the processor.
The thermal compound should be applied so thin, you can almost see the text on the die through the compound. Do not use any on the heatsink just the CPU. Some recommend putting compound on the heatsink, then completely wiping it off... I disagree; I prefer that surface to be virgin clean. The compound on the die will do the job. Remember, the less you use the better the heat will transfer. Spread it with a strait razor or a credit card edge.
If you were to remove the heatsink after it has been installed properly, the text from the processor will leave an impression on the base of the heatsink where it came in contact. (of course it will appear reversed)
You can use Arctic silver or other silver based thermal compounds however I have never had a problem with the Radio Shack thermal compound and you do not have to worry about that stuff shorting out your processor like the silver based compound can.

  • Update attempt on iPad2 using Windows PC. Keep getting error 3004. What the **** is going on? Apple care not helping much. And I have downloaded latest iTunes version and restarted and it still says there's an iTunes update available for same version.

    Disgusted

    Your firewall or av software is screwing everything up.
    Turn it off.
    Straight from Apple:
    Errors 3000-3999 (3002, 3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443. This may be because out-of-date or incorrectly configured security or firewall software is interfering, an old version of iTunes is installed, an entry in your hosts file redirecting requests to gs.apple.com (see error 1004 above), or because of your Internet proxy settings. If you are using a proxy, try without using one or with a known-good network. If that does not resolve the issue, follow iTunes for Windows: Troubleshooting security software issues. Error 3014 may indicate that you need to free up more disk space on the computer before trying to restore again. Error 3194 most likely indicates you do not have the latest version of iTunes installed Update to the latest version of iTunes.

  • What may be happening with my macbook pro 17''?

    what may be happening with my macbook pro 17''? I made a few months ago upgtrade 4GB of memory to 16gb, everything was going well until the graphics began to dance and fails, until it gave bluescreen ... never seen it in a mac. Serial Number C0*******F92
    Graphics card Intel HD Graphics 3000 512 MB​​? Was never 512mb graphic, do not know what may be going on .... please help.
    <Personal Information Edited by Host>

    The graphics memory increases to a max of 512 when you upgrade the RAM. The RAM is actually the most likely culprit, since it's been recently changed. Put the original RAM back in and see if your problem goes away.

    I have been interested in computers for a long time. My husband and I had one of the first TRS-80 computers from Radio Shack, and we would have likely followed the Windows path, except a blessed event intervened and our interest in computers was sidetracked by raising
    a toddler.
    I had my first experience with a Mac (a Performa 630 CD) in December of 1994. Our 7-year-old son was using Macs at school, and was as interested in computers as we were. We had been out of the game for a long while by this time, so thought it was wise to buy a computer one of the three of us (7-year-old Zach) could use.
    I thought, "Well, by next year, I'll learn enough to do the income taxes on it." In January, I saw Zach playing around with Quicken, and I saw how easy it would be to do our taxes with it. I had them done faster than I'd ever managed it before.
    I guess that's my big first impression.
    I told Zach he'd be sorry about wanting a Mac because I knew the gaming thing was on the horizon. Sure enough, when he hit his teens, all his friends were gaming on Windows boxes, and he now uses XP. He is in his second year of college, a Computer Science major, and he and his dorm-mates have Vista available as a free download on the college server. Not one of them has installed it. I don't see how Microsoft thinks they can sell it if they can't give it away.
    I tried Windows 98 and Windows XP, and my reaction was "Why on earth am I banging my head against THIS wall, when my Mac does everything I want to do?" And back I went to my Mac.
    With Intel processors and Parallels and Boot Camp, Zachary may come back to the fold. His next computer may be a Mac.

    Ok, I got a vision m for christmas and everything worked fine. I stopped using it for?a couple of months and then my mom got a v plus. I wasn't getting the connection error with the MTP device stuff. Now I plug in my vision m and I am getting the same problem. This is starting to piss me off. I got my mom's to work on my old comp upstairs. But I will not allow mine to be linked to that computer. All my music is on this computer. I don't know what is going with the creative products, but creative you really need to figure it out.

    I agree. I've had problems with my old player (Zen Micro) and my new one (Zen Vision: M) which are connection issues. Sometimes they connect, and others they don't.

  • Really having problems with organising documents in pages. For example, deleting pages deletes the whole section and I cannot insert a section break as its greyed out & sending an object to background deletes several pages - what the **** is going on???

    Really having problems with organising documents in pages. For example, deleting pages deletes the whole section and I cannot insert a section break as its greyed out & sending an object to background deletes several pages and trying to insert a text box autmatically creates new pages- what the **** is going on??? Is this programme really this badly thought out? I thought everything apple was supposed to be intuitive!?!?!? Help.

    You can not insert a section break into a textbox.
    You appear to have a lot of objects with wrap set, that once you take them out of the flow of text (by sending them to the background) causes the text to reflow and contract into fewer pages. Pages is almost unique in the way it forms up pages in Word Processing mode only so long as there is text on them.
    I suspect you probably have hammered away at returns, spaces and tabs as well to position things, which only works to add to the mess.
    Download the Pages09_UserGuide.pdf available under the Help menu and swot up a bit on how it works.
    You may find this a usueful resource as well:

    PS There is quite a lot of programming in OSX that is far from "intuitive". Pages is easy at one level, when using the templates, otherwise it can be quite frustrating.

  • What is the problem with fonts changing to myriad pro? Is this problem ever going to be resolved? Its driving me mad!

    What is the problem with fonts changing to myriad pro? Is this problem ever going to be resolved? Its driving me mad!

    Browser Dog, Amy,
    The default font remains Myriad Pro until you change it, either in the RGB/CMYK Startup files or in the preferences, options depending on versions.
    Concerning missing font names, I believe this may solve it:
    Open System Preferences and go to Accessibility. Next, select Display from the source list along the left, then check the box labelled Reduce transparency.

  • What is the problem with my desktop imac, that ical has frequent pop ups that say I am not connected to the internet, gives me an option of going offline.

    What is the problem with my imac, that ical has frequent pop ups that indicate I am not connected to the server. Gives me an option of going offline. This seems to have started when I began using icloud with all of my devices.

    I discovered a simple work-around that is successful (at this point in time anyways) on my IMAC/Maverick when sending attachments (not inline or embedded) to PC users.
    There are several threads in here on why attachments embed in mac mail when sending to PCs, and I have had similar issues. Not sure where the fault lies, but other than purchasing an additional program to make mac mail work as other mail programs work when it comes to attachments, I found no real solution that worked for my business PC folks. I did all the right things - sent my attachments in mac mail "windows friendly,"  "plain text," and "attachments at the end" and still got complaints when sending to my pc workmates using Outlook.  I tried another suggestion I found here - zipping the files and sending the zipped file, but my workmates did not like that either and still asked why? 
    By trial and error I discovered that when I attach any pdf to the email as well as the questionable jpgs, the attachments arrive in their PC inbox as attachments that can be used as needed. I don't know why this works, but it has made sending attachments a happier task for my business group.
    I would be interested to see if this works for others.

    This issue can be caused by a corrupt local snapshot index. The procedure below will temporarily disable local snapshots and force the index to be rebuilt.
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ If you’re running OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
    Drag or copy — do not type — the following line into the Terminal window, then press return:
    sudo tmutil disablelocal
    You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command.
    To re-enable:

    iPad 2 with iOS 7.0.2 -- safari loads fine as does gmail.  However, Sir,i App Store and youtube among other such things will not connect.  I am at a loss. What could be going on?

    Try a Restart. 
    Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
     Resetting your settings
    You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.
    Resetting your device
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears. Apple recommends this only if you are unable to restart it.
    Or if this doesn't work and nobody else on the blog doesn't have a better idea you can contact Apple. 
    Here is a link to their contacts with most of the information below.

  • IPad (4th Gen) What is a good case that goes with the "iPad Smart Cover"?

    Hi,
    I'm currently looking for a case that covers the aluminum back that also goes with the iPad Smart Cover. Thanks!

    I've bought a ton of back covers. It's been hard trying to find the right one. I've settled on two really good ones though:
    Caudabe Shell: This one's my daily driver, so to speak. I've got the frost version and it looks really good and has held up really well. Price is very reasonable too.
    Switcheasy Cover Buddy: I like this one as well. Only thing is that they don't seem to have a frost version. They just have opaque colors, which I'm not a huge fan of. This is also a little bit more expensive than the Caudabe cover.

  • Thermal compound replacement, RESULTS and PICTURES

    YOU CAN HAVE A MACBOOK PRO THAT ISN'T SCORCHING HOT!!
    (note that this will NOT fix any whine or moo; they are unrelated problems)
    Here's how.
    My Mother's Macbook Pro (Or Cookbook, if you will) Arrived a week ago today. I played around with it to make sure everything is alright because my mother doesn't know how to check for things like dead pixels, bad ram, or cough improperly applied thermal compound.
    One of the first things I noticed after turning on the new MBP is how totally sweet it is! The second thing I noticed is how freaking hot it is: I recoiled in pain from the Fn key bar the first time I touched it. Disappointed, I started searching the web and sure enough, pretty much everyone who owns one is complaining that it's too hot for comfortable use.
    Apple calling this a "notebook" instead of a "laptop" is a total semantic cop-out. It's a PORTABLE COMPUTER and I must be able to trust it around my dogs, children, valuables without the MagSafe burning up or the battery swelling and bursting.
    I don't have objective figures for just how hot it was, but it was right about at my pain threshold above and below the belt, and sometimes over it. I couldn't hold my hand to it for more than a few seconds. In particular the area to the left of the touchpad was of concern. I do have before-and-after figures of the CPU and HDD; I invite yourselves to look at them:
    Before After (Temps in degrees C, ambient 25 C)
    50-60 26-35 CPU (idle)
    76-85 56-65 CPU (load)
    41 33 HDD
    In particular the HDD figures are a great relief. HDDs are notoriously sensitive to temperature and even a few degrees C can cut their lifetimes significantly. Furthermore the area is now cool to the touch and I can once again rest my left palm on it without discomfort. The ranges are due to the fact that the sensor inside the core duo is flaky. In 5 seconds it can run anywhere from +-5 to +-10. Nevertheless it is accurate enough for our purposes. Below are photos, procedure, and a rough outline of test methodologies:

    Here's the idle scenario before the procedure. The computer has been on for hours (days really) and I'm doing the work I normally do on it. TextEdit is open (to a little project I'm working on) with firefox and the temperature monitor. Alt-tab is to show that those are the only programs running. CPU temp is dead at 50 C. This is INSANE for an idle figure on ANY computer; desktop, laptop, "notebook" or otherwise.

    The operation area and stress test. To stress the ATI chip I've jacked up the resolution, run a couple of quartz programs, SNES9x (a hardware emulator; the software shown is called "Energy Breaker") with a brutal multitasking OpenGL hardware renderer, and Google Earth. To get the CPU going I have Adobe's Lightroom processing thumbnails, and again SNES9x. For various I/O I have two shells executing yes > /dev/null, a USB mouse plugged in, and all the HDD access from lightroom. I figure it paints a pretty good picture of the "worst case scenario" of hardware stress for a laptop like this.

    The CPU core(s) is at 76 C. I should note that at this point, as hot as the CPU is, overall the case is really not much hotter than it was before. In other words, it's just as unacceptable.
    At this point I turned her off and dug in. I used a howto from Ifixit to serve as my guide. The procedure went without surprises until I got all the way to the logic board.

    Dear lord!! That is an obscene amount of compound. It's casting a shadow over the rest of the board!! This gray gak is piled on so thick, it's no wonder the cooling system couldn't work effectively. It had even gotten all over components nowhere near the dies. That definitely cannot be good for their lifespan. Here's a shot of the heatpipe:

    Terrible. Thermal compound has been squished out all over the place, including the chassis itself. This explains why it was getting so hot. A photo from the MBP service manual has been floating around the net, illustrating that this gross amount of compound is actually according to procedure.

    Clean as a whistle. After removing the bulk of the compound with q-tips I used ArctiClean 2-step process to emulsify the rest and remove it with paper towels. You can see it's not perfect but it's close enough for me. I'm not overclocking this thing; I just want to run it "in spec" and have it not burn me. At this point, the CPU dies and the heat pipe interfaces should have mirror finishes. It's an overclocker's dream, and Apple already did the work for me.

    This is how I applied Arctic Silver 5 to replace the compound I removed. Squeeze the tiniest little bit out of the syringe directly on to the die, and scrape it across with a flat edge (they recommend a razor blade but I just used a plastic ID card). Take the amount of compound you see on the Core Duo (on the right) and make a flat, even layer like the one you see on the ATI (left).

    Turned it on and went straight for the hard stress test, after making sure everything was OK of course =) Wow! It reads 58 C in the screenshot, and doesn't go above 65C!! Moreover, there isn't even a bit of warmth above the Fn keys, and the HDD area is cool to the touch. I'd call this one a complete success. I'm idling right now and the temperature reads between 26 and 31C. Even the bottom is just slightly warm to the touch. Now I have a real laptop again!
    So why did this happen?
    There's a lot of confusion about the way the Macbook Pro cools itself. I admit it's confusing. Basically, Apple is shipping Macbook Pros with one cooling system, and replacing the thermal compound changes it into a very different system. Let me try to explain what I learned from digging around the hardware.
    1. The built-in thermometer in the CPU is flaky. That's why you have to access it with a kernel extension and all kinds of hacks, and why Apple circumvented it completely in the cooling system. That's right: the MBP cooling system ignores the Core Duo temperature entirely.
    2. The cooling system consists of a convective (my guess, I don't think anyone really knows what kind of) heatpipe which is in the base, directing heat out to two heatsinks which are then to be cooled by two fans if need be.
    3. There are two temperature sensors. One is on the heatpipe itself, and the other one is on the chassis just next to the right fan. Probably the hardware monitors these temperatures and the differential between them to decide when to activate the fans and how long.
    4. Behavior before the replacement procedure: The CPU core would get hot, hotter than I've ever seen a CPU go, at 80-85C. Most people confirm their MBPs also exhibit this. Where was this heat going? Well the fans didn't turn on until I put it at full load. Even when the fans did turn on, there wasn't much warm exhaust coming out of the vents at the back. The chassis heated up until it was unbearable, and most of the excess heat was being radiated away from it.
    To sum up, the ineffective thermal interface between the CPU dies and the heat pipe was inhibiting heat from tripping the fan sensors. This explains why the fans didn't turn on until drastic temperatures were attained, and why the chassis got so hot. Essentially, the chassis was serving as a big heatsink for the CPU, which is the only reason it didn't overheat and shut down.
    Effective, Apple, but not quite appropriate.
    5. Behavior after the replacement procedure: The first thing you notice is that the fans scream from the second you turn the thing on. They aren't going full blast but pretty close to it. An effective thermal interface using an APPROPRIATE AMOUNT of AS5 (anything would do but I figured if I'm applying thermal compound, why not go for the authority) allows the heat to go straight from the cores into the heatpipe, tripping the sensor early and fast. The fans come on, I can feel hot air coming out the back, and the chassis now removed from the thermal equation is cool and comfortable again.
    Of course, the thermal equation is different from before, and from the way Apple has tuned the fans to work from the factory configuration. This is more cooling than we probably need, and I foresee an update to Tiger allowing us to choose the thermal/noise tradeoff for ourselves.
    Well, I hope that explains it, and I hope that those of you still suffering the abuses of your "in spec" MBP can take some hope from my findings, or are emboldened to go ahead and repeat the procedure yourself. I will post informative links here.

    Remember if you ever open up your MBP to NOT BREAK ANYTHING and please, always read the instructions before you reach in. =)

    methanol, my conclusion is that Apple's specifications for thermal grease application are technically sound. As a corollary, I put the postings claiming that isn't so in the Urban Myth category.
    There's a lot of technical literature on design and manufacturing specifications for thermal grease use, the kind of literature that appears in professional technical publications and is written by engineers. That literature supports Apple's thermal grease specifications. Putting it another way, Apple's engineers have a lot more technical training and experience than the average hobbyist who is working from the directions that came with Arctic Silver.
    Yes, my computer has the "messy" looking application of thermal grease. No, it isn't inappropriate and doesn't need to be modified, and Apple did not make a quality assurance/quality control mistake.
    Posts about the thermal grease modification began appearing several months ago, followed by Hardware Monitor charts showing considerable differences in "before fix" and "after fix" temperatures. I found, however, that I could easily replicate those before and after charts, and my computer compared favorably with the "after fix" temperature charts. Why? There was no quality control on the generation of the charts. And of course some owners damaged their computers in the process of taking them apart and putting them back together. Not a good idea, in my opinion.
    Painstaking manual application of thermal grease might result in an insignificant drop in CPU temperature, perhaps 2 or 3C. Trying that in a mass production situation would result in more CPU failures.
    True, some people got very significant reductions of case temperatures. That will happen if the sensors are not working (broken connection) and the fans run full out.
