That should not be the case with modern CPUs, since the TSC should be
constant+invariant (non-stop) and therefore won't change when the clock
speed does. It has had these properties on Intel since at least Nehalem.
I believe that it is also synchronized between cores on modern CPUs.
With these
last time I checked (before the '66 fps' update) it happened both on
windows and on linux.
The biggest effect I experienced was when running with speedstep AND turbo
boost enabled: it made the frequency jump from 1.something GHz to 2.8 GHz
on a i7-920 cpu. Servers were running at 72 ticks instead
If anyone has steps to reproduce this, including the specific Linux kernel or
Windows version, I'd love to know about it. Thanks!

On my existing dedicated server i rent, its a dual core and at one time there
were 3 servers and with all servers full (3x 20 slots) - there were no lag
spikes or performance issues and the servers werent even locked to using a
specific core.
When i had my new servers built, i couldnt afford

That's wrong.
Srcds reported CPU speed is *not* used for timing, I'm pretty sure it's
sole purpose is for benchmarking. It definitely has *no* effect on
gameplay.

SRCDS definitely DOES use the benchmarked speed for timing, hence the
problems seen when a server is started on a non-turbod core. Once the
core becomes boosted, the game runs much faster than it should, and
hence vice versa if the core is boosted prior to launching the server
and the speed is
Can you reproduce this on a reasonably vanilla kernel? I see no reason why this
would be the case.

Would Intel's Turbo Boost negatively affect server performance?
P.S. Intel Turbo Boost is a built-in feature of certain processors that
dynamically overclocks the base frequency of the processor (eg. going from
3.50Ghz to 3.80Ghz) during periods of high load.
Overclockers tend to turn it off since it can cause instability of the
system is already manually overclocked (it's tweaked after default stock
clock). If you hadn't overclocked, it's safe to keep it on. At best case it
improves perfomance, at worst it's the same as running without it.
On Wed,
Yeah, in an overclocked system it attempts to underclock the processor
back to its base frequency, which can at best removes the whole point
of an overclock, and at worse causes severe instability.
But as was stated, if you havnt overclocked the machine I don't see
why it would effect performance.
It helps me a lot. As far as I know it hasn't done anything negative,
except maybe turning off due to some SuperMicro power saving feature that
you cannot seem to disable.

if you see cores frequencies that keep changing, you will probably want to
disable it.
Also you should keep in mind that SRCDS runs a benchmark of the CPU the
first time it starts: if it starts when the box is

Turbo Boost is supposed to be controlled by the OS, and there is a lot
of noise about it not working at all with linux. Has anyone here running
linux verified that Turbo Boost actually works?
AMD uses TurboCore, but I disable it on my boards and just up the clock
a couple hundred MHz. YMMV,

Yes, it does work, if you are running the correct kernel version
Yeah, i figured it would cause some problems.
Thing is, im planning on putting between 4 to 8 SRCDS servers on each machine (i
have 2 machines).
The specs are:
Intel® Core™ i7-2600K Processor (8M Cache, 3.40 GHz, Multi-Threading Enabled)
500GB Raid-0
16GB Dual Sided Memory
