Can a Bottleneck (CPU or GPU) Freeze a System?

[Aderes Devorah]

Hi all

I know that any number of things can cause a PC to crash, but mine is still seizing up completely and needing a forced reboot (at the plug).

The last time was when I was doing some rendering. Before that it had gone a good five days and I was hoping it had resolved itself.

Surely my 8350 and 7950 are well matched? Is it likely that one is bottlenecking the other?

I was going to treat myself and go Crossfire this Christmas. Until I sort this, that idea has "Gone for a Burton"!

Cheers in advance for any help.

Best

A bottleneck shouldn't cause a freeze.

Most likely your OC is not stable.
If you have the thermal headroom increase your vcore.

Try running with the standard 200Mhz FSB with 22.5x multi and 1600Mhz RAM.
Don't push NB speeds too high, don't go over 2400.

It isn't a bottleneck causing your lockups.
Seems your ignoring the obvious here and going of on a tangent.

Assuming your rendering is purely on the CPU and not on the GPU it does sound like a CPU OC problem. It's nothing at all to do with bottlenecking. Obvious question, but have you changed anything?

It could also be a failing PSU, or even memory issues - but I would try increasing the voltage a little as suggested, and if it doesn't help, go back to stock clocks/voltage to rule out the OC.

Either unstable CPU overclock (as above) your Un-stable RAM overclock.. More likely the RAM.. As a failed CPU overclock tends to BSOD.

Sage advice. Thank you. You may very well be correct about my tangential logic.

Makes sense. Thank you. I am going to re-seat the RAM as well just in case.

Will do. Thank you.
