Do you guys enable EIST and Cstates and if so how do you configure Cstates?

RAM frequency matters very little, but if you want to involve more ram into the process, there are two more things that can be modified.
- First is “--rc-lookahead 80” which can be set to 160 and up to 250, and this setting won’t affect other things negatively. This should add ~ 1.2GB of extra ram (for 250)
- Second, you could run the encode on “medium preset” (not to be mistaken with “process priority”). BUT, running on medium preset will affect other things negatively (reduce cpu stress), so i don’t recommend it.

This is a forum on the internet he needs to get use to people asking the same thing over and over, that's what these forums are for. more specifically you in the OP has even encouraged it.

Problems? Ask here! Do not spend 5 minutes, tweak 2 things, get a bad overclock, and rage!
Comments? I'd love to hear it!
Questions? That's what this thread is here for!

So reading this I thought it more than reasonable, versus searching all night, just to ask from the people who OC everyday. Not trying to sound like a jerk, but giving a simple emoticon response is rude, and against the ToS. We should all be understanding and welcoming to nooobs, instead of conveying such a response.


That being said so far my OC stands as 4.5GHz @ 1.325v Uncore at stock. We shall see if it lasts.

Thanks

I tried and logged a few things:

I copied "test" folder into a new directory, modified script you linked and then updated the encoder. I ran it, my performance was terrible - like 2.5fps terrible, and cpu load looked like this - i know you used max of highest thread, but this CPU load stat was usually higher for me:



I undid the changes and ran again, 3x loop, then compared it to old encoder. I used a different (old) batch file by accident though, so need to re-take those results. On it now (checked while writing this post, derp)

pZqru3c.png

Here's old encoder (blue) vs new encoder (green). Red thrown in from the HT changes to batch - i stopped blue early because i needed to write post and rush off to do something else

I think the number difference is mostly just from different amounts of idle time at start. They're quite similar (old and new encoder) but those HT modifications lower CPU usage on max thread and especially total, while also halving encoding speed

As you can see red number for max thread is higher - like 99.6% - but it's worse on the graph. That's just because i started logging after load was applied and stopped before it ended. I think both of the other runs can beat that number, as shown by less dips etc.

This was 500ms sample time

Not sure if i forgot or missed anything, gotta run now so i'l think a bit more later thumb.gif

I let it run to about 100 frames then sampled a minute or so of r24xx encoder w/ new batch (no modifications)



pretty much solid 100% on highest load thread, 98.2 average across 8 thread

That slowness comes from “--me esa” but i thought that it will scale in cpu usage on HT cpu’s (on my non-HT they have the same cpu usage)
From what you are saying, it doesn’t, but you should have let it run for more then a min and a half for the results to be more clear.
Delete “ --me esa” (along with the break in front of it), but leave “--subme” to 11 and try again.

I will edit the post to let others know that it doesn’t improve cpu usage on HT chips.

There is no reason not to run EIST (SpeedStep). A lot of us also have all C-States enabled because we like seeing almost 0v being drawn at idle.

The default for Z87 mobos is to have C6 & C7 disabled. If you have a newer PSU with D2D circuitry you can run C6 and C7. Since many budget PSUs are not capable of C6 and C7, that's why it's off by default.

Here's how I have my EIST C-States set:

Enhanced Intel SpeedStep Technology - [Enabled]
Turbo Mode - [Enabled]
CPU C States - [Enabled]
Enhanced C1 State - [Enabled] (FYI this is sometimes called C1E, now it's called Enhanced C1 State by Asus)
CPU C3 Report - [Enabled]
CPU C6 Report - [Enabled]
C6 Latency - [Short]
CPU C7 Report - [CPU C7s]
C7 Latency - [Short]
Package C State Support - [CPU C7s]

For above post, you made a mistake writing my name, and also in the code box it's still including --me esa i think~

Curious how you got so knowledgeable of encoder, would you like to add me on skype also~?

That being said so far my OC stands as 4.5GHz @ 1.325v Uncore at stock. We shall see if it lasts.

I agree with you. Haswell OCing (any CPU OCing in my experience) can seem like a black box or an arcane art at first.

But it usually boils down to isolating a very few variables and changing those. For Haswell there are only about 5 things to change -- 3 voltages and 2 multipliers:

Voltages
1) VID
2) VRIN / VCCIN / Eventual Input Voltage (I'm sure it goes by other names too)
3) CPU Cache Ratio Voltage (uncore / ring bus)

Multipliers
1) Core multiplier
2) Cache ratio multiplier (uncore / ring bus)

That's it.

There are a lot of other things to mess with like LLC, disabling onboard devices etc., but as for as OCing (non-extreme) that's about it.

Follow the methods in this thread that Darkwizzie and others have mentioned.

1) Isolate core and do not worry about cache ratio
2) Once core is stable, then move on to cache ratio
3) Only change one thing at a time (very slightly) and test for stability. If stable, change again and retest.

thumb.gif

If you're at 1.325v (VID? Vcore?) you probably need to raise VCCIN. The rule of thumb is .5v to .6v above VID for VCCIN. At 1.325v you will probably need ~.6v above your VID, so 1.925 ish. But it could be more or less. I needed less than .5v above VID (my VID is 1.280 @ 4.5GHz) with LLC on Auto to get stable.
