Something wierd with my hypertransport
Hello, im a light overclocker and dont know all that much about it, i sorta understand about each thing that happens when you overclock and AMD64 but this hypertransport just baffles me . . . just when i thought i got it figured it just gets weirder
Ok i have a K8N Neo2 mobo with a amd64 3200+ seated and happily running at 2.2ghz at about 113f (45c) under full load and 103 under idle. Temps provided by speedfan. The cpu cooler is the Scyth Universal Heatlane cpu cooler paired with Nanotherm PCM. Komusa 3700 dual channel ddr ram (512)
Ok my thing is when i try to manually overclock my cpu to 220 with my ht at 5x i cant seem to get the pc to reboot without having to drop the ht to 4x or without lowering the fsb to 205. . . now thats manual. . .Right now im running the fsb 220 and have the ht at 5x . . .the way i was able to acheive this was using the auto overclocker under core center. BTW im running 100% stable, i have been able to run multiple apps paintshop pro9 editing a picture at pixel ranges of @ 15000x11000 with a bunch of apps running in the background, windows media with a dvd playing, trillian pro2 running idle aswell. SiSandra's burn-in ran fer like 4 hours with no problem. I have been able to run super pi no problem too, i dont know if that would be enough proof of stabilty fer you heavy overclockers out there, i have been running more than 8 hours each day fer 3 days at this new setting. I cant test nE games my msi nx6800-td128 is on its way fer a second RMA. so i cant acutally test under a heavy game. Im running a heavily stressed ati rgace xl pci card, which has been showing graphical glitches and oddities since i put it in when my first msi vid card went funky. I hate this card, i got help from ati tech and they told me it was being stressed in my machine . . but meh
1. why was i not able to achive these clockrates while trying to manually set the settings to what i have achived with the msi core center auto-overclocker?
2. has anyone else been able to achieve this with a similar setup?
3. and do pci graphic cards actually get mejorly stressed on 64bit machines?
thanks fer any kind of reply, i just thought my HT results were wierd. . and not seeing anybody post anything similar to this . . i thought i should share. So am i lucky or is this something that someone could explain to me @.@
thats what my understanding was aswell, maybe there is something im missing . . . I just didnt get why i can do that software and not by the bios, i did ferget to mention that everytime i start the pc i have to reset the overclocked setting but it works fine after i do so. . i am just looking fer an answer to why i can do this via corecenter and not hardware. I didnt know about having to drop it 3x when clocking to 250 LOL but i have been able to overclock my cpu while at 4x to about 236, then my ram craps out on me, but im happy at 220.
Sorry the signature in my last post was not updated, its fixed with my current config now. but anywho i did notice a lag once and a while while running my machine like that fer a long while under load . . .but i guess that would be normal. hopefully somebody will be able to help enlighten both of us on this, its certianly got me puzzled still lol

Google said something wierd is going on on my computer...
Today, when I woke up I had Google notice on my gmail account that something wierd is going on on my computer. I had to enter my telephone number, then Google sent me SMS with code so that I could enter my account. Then I had to change my password. In my mailbox I found that someone was sending mails from my e-mail acccount. How is that possible? Did someone break in my iMac? Do I need additional software for Firewall and Antivirus?
Thank you in advance for your answers.
Kind regards,
KlemenHello k:
I do not use Gmail. However, the problem is, I think, on the Google end. The mail resides on a Google server, not anything to do with Apple.
I seriously doubt if the penetration was to your Mac.
I would definitely not buy A/V software. There are NO viruses that affect a Mac running OS X - NONE.
You should, if you have not done so, be sure that the built-in OS X firewall is on.
FWIW, I had a similar problem with one of my AOL mail accounts. The problem was definitely on the AOL side.

Wierdness with NIO socket on Solaris 2.10 part I
i tried the following NioClient and MockServer, and saw some weird behavior.
1. If i run both the client and server on the same machine on Windows, the client connects to the server, queries the instrument and gets the list of instruments back.
2. if i run both client and server on the same Solaris 2.10 box, the NioClient doesn't get anything back from the MockServer, not even an ACCEPT
3. if i run the client and the server on different solaris 2.10 machines, they work fine.
have anyone seen this before? can sometone sheds some lights?

My phone wont let me download anything even free stuff or update.it keep saying something wrong with my billing info so i fix it but still cant download.I signed out sign back in still nothing please help i'm getting angry
If it says your billing info is wrong that means that your credit card issuer is refusing to approve your account. You will have to solve the problem with your bank or credit card company.

I bough a used Macbook Pro mid 2009 that came with OS 10.8.9 it didn't have a backup restore disk with S/N W8******66D
When trying to view some youtube videos; a window would pop up saying "it needs adobe flash player is required for video play back get the latest flash player" but after downloading the file and during installation would have errors and will not installed.....tried to reboot and install again.....but still the same.
The othe thing I had noticed is when using a good Bose headset with mic the sound output would noticed the headset and then switch from headset to Internal speekers and headset.....thinking that there might be something wrong with the plug in port of the computer or the headset.....the headset works with no issues on my iPad so there must be something wrong with the computer.....tried to move the plugin around the port but no change....while the headset is plug in can hear a short clicking noise and the sound would get lost and back again......but with nothing plugin to the port there is no issue with the sound or mic.
Thanks for your feed back......it looks like I have two different issues one is a software issue and the outher is a hardware issue
<Edited By Host>The "restore disk" is built into the Mac. See About Recovery.
Need more specifics about what error messages you got while installing Adobe Flash.
However, you can almost avoid Flash altogether by setting YouTube to play the HTML5 version instead.
Click the Try something new! link at the bottom of the YouTube page.
I don't know about the sound issue. Might be hardware as you think. Try other headphones to check. -

There is something wrong with the volumes buttons in my macbook pro, every time i pressed the one who raises the volume, it leads me to the screen where (i do not no what its called) the background is black with the date and time and a calculator. However, when i lower it, my safari tab goes out of the screen. What do you guys think i should do? I'm getting very nervous.
hey HAbrakian!
You may want to try using the information in this article to adjust the behavior of your function keys to see if that resolves the behavior:

I synced my ipod to my computer and all my music disappeared. I tryed resyncing it and it would only sync my apps and not my music. I cant add music to my ipod. I something wrong with the USB port in the IPOD, the USB Cord, or ITUNES itself. Itunes still shows that all my music is there on my ipod. Itunes is recognizing that my ipod is connected, but it doesnt recognize that theres no music on my ipod anymore. Im so sad. Someone please help me. I miss my music.
The music sync is one way - computer to ipod. The only exception is itunes purchases.
The ipod is not a storage/backup device. It simply mirrors the selected content of your computer.
As the music came from your computer in the first place, it should still be there and in your backup copy of your computer. -

Installs fine for me, so I'd guess you got an incomplete or corrupt download. See the Further Information area of Troubleshooting issues with iTunes for Windows updates for direct links and download a fresh copy of the installer.

Something wrong with my CD/DVD drive??
I think there is something wrong with my CD/DVD drive. here are the things I notice:
At time the CD drive will act up and make a little noise (same normal noise as when mac starts up) but for no reason
When I put my mac on stand by, my CD drive decided to make some noise and then it woke the computer from sleep mode
Any suggestions? What could be the problem here?
Thanks.

Good luck hope it works. -
Is there something wrong with this table row definition?
I have am supporting a coldfusion app that manipulates several forms. One one particular page, there is a form that consists of several tables. The last 3 lines of the last table are

Now whne the form is displayed on my page, I always see the line of text Description and the line of text Direct expenditure to benefit a candidate or officholder (in bold above). But I never see the line of text Is expenditure a contribution to a candidate... (in italics above). It seems so simple but I can't figure out why that line does not display!! Is there something wrong with that tr/td definition?Have you tried removing the ID? Just to see if some CSS might be using that ID with a display:none or visibility:none statement?

Is there something wrong with a Oscar Gomez Fuentes 2Channel oscilloscope
Is there something wrong with a Oscar Gomez Fuentes 2Channel oscilloscope or are my devices configured wrong. I have DAQCard-6036E and SCC-2345 with SCC-Ft01 and SCC-A10 modules. The problem is that when I am measuring with A10 it effects to FT01's RMS and DC values. But when I am measuring with Ft01 everything is ok. So what's wrong?? I attached a picture of a front panel.
Attachments:

Do any of the signals you are measuring have high output impedances (> 1 kOhm)? If so, you may be seeing cross-talk (or ghosting). Below, I have included links to a number of documents that discuss this issue and methods for eliminating it:
