Slight problems with stutter - HELP

[RockingDude]

I just upgraded most of my computer.
D920 > e6300
4200ddr2 > 6400ddr2
7800gs > x1950xt
foxconn > gigabyte s3

I'm now getting severe slowdown when doing HD intensive, and computer intensive tasks(copying files, Oblivion). So much that many times my (dialup ) internet disconnects, and sound gets garbled/fuzzy.

My cpu is only at 1.25v ram 2.1v @ 429 1:1 so cpu is about 3 ghz.

I don't like going over that because for some reason my arctic 7 is only keeping cpu at 54c at idle according to TAT. Orthos hits 60c and TAT hits 70c.

1. Why am I getting this severe slowdown?
2. What's with my high idle temp at that low voltage?

Thanks for any help!

Have you done fresh OS installation? Do you have the latest platform and video drivers?

 

[RockingDude]

Brand new OS installation, had to install a few times because when I disabled Marvell gigabit lan, my computer would massively slow down, I still don't know why that happens, but I figured it out and kept this install. I upgraded to v8 bios, and all other drivers are up to date.

Check to make sure your HD is in Ultra DMA mode, not PIO mode.

 

[RockingDude]

One was in pio, so I corrected it, but when doing things intensive things, I still have mass lag. I can't tell if it's power related or what, it's really frustrating when it's all new components.

 

[RockingDude]

Well, I tried running Vista, and it seems to be running fine, but I haven't done much intense things, I'll try some and repost.

My setup is almost exactly the same except for the cooler and I don't have temps those high (or voltages that low). Either try reseating the HSF and reapplying the thermal paste or get a better cooler? It does sound like something is wrong with some drivers, though. Have you tried getting the latest version of everything from the gigabyte website?

 

[Paperdoc]

I'm thinking along the same lines as Roguestar. Your computer slows down significantly when you run heavy jobs, and the CPU temp is VERY high. That looks like a heat removal failure, and the system is just using its normal protection devices to slow down the CPU and avoid overheating. Try addressing the heat / temperature problem first. After that's resolved you can look for software and driver oddities if the problem persists.

What Paperdoc said-- from Intel "If it runs too hot, the CPU has inbuilt protection and may go into a thermal throttling condition to avoid damaging itself. In the worst case, the system may shut down." Make sure your HSF is properly seated on the CPU and you are using just a hint of thermal compound (too much will hamper heat dissipation to the HS)

Maybe add another case input or exhaust fan? All if the issue is heat.

In the first example, you can see how the game on the screen (FPS) bogs down very quickly with a little added heat in the system.

Your HSF is good enough. It keeps my processor in the low 40's under load. Fair chance there's a problem with how it's attached.

 

[RockingDude]

My 4 pins are all attached into the mobo correctly, and I'm using the default spread of thermal compound that came with the ac7. Could I just have a hot chip? It's an engineering sample B0. Gigabyte's thermals say 20-30c but tat's say 54-60c.. I don't get it.

I'm also having a problem in both xp and vista with my x1950xt's vivo. The video in is constantly jerky, it will play for 2 seconds and then loop like a .2 second frame.
