ATI Radeon HD 5770 in MacPro 1,1

Hi Grant,

Ok perfect with regards to 5770, I havent noticed the issue you linked too but thanks for this!

WiFi is good and internet connection good to, the video always loads quickly but playing is always very stuttery, sound is good though but video lags behind.

RAM is a possible which I have thought of, for now getting to know wether to upgrade or not and hoping it maybe a simpler cheaper soloution... Running 6gb 667Mhz DDR2 FB-DIMM RAM atm..possible cause for upgrade?

I've noticed that Firefox is always running 100%+ CPU or there or there abouts, indicative of ram upgrade?

Green/Free - 225mb roughly

Blue/Inactive - 1,70 gb

Red/Wired - 504 mb

Yellow/Active - 3.74 gb

Page outs - 4.67 bg (0 bytes/sec)

Thanks for the prompt response

Those numbers indicate you are running short of Real RAM for all the programs you are running at once. Solutions include Quitting Applications you are not using before starting a Video, or adding more real RAM.

A non-trivial number of PageOuts since startup is indicative of more than once when there was absolutely no spare RAM available.

Ok, thing is, I'm not running alot of programs whilst this issue is happening, firefox could be sucking up alot of the ram though!?On Sys mem real memory is at 3.3 gb ram for firefox, I've 6 installed!?

I've quit almost all programs and the issue still remains!?

Any other possibilities other than ram?

Whats a "normal" pageouts? Does this stay with the machine once it has maxed out, rebott put this back into a normal range?

Cheers

If you are not running a lot of stuff while this is happening, you may need more real RAM.

The PageOuts counter is a cumulative counter since last Startup, with current amount (in parentheses). A good value for it is near zero, since it is indicative that you had to endure paging active stuff out to make room for paging something else in.

Mavericks uses memory compression and uses memory somewhat differently, and this display changes for Mavericks and later.

To reduce Browser memory consumption, reduce History tracking to ONE DAY. You will save a lot of RAM, but may occasionally have to retype a URL or re-Search instead of autocompleting it.

Ok, thanks thats answered a few of my issues and questions, I'm unable to give points on this one, your a star in my book though 😉

Many thanks for all your help with this and the other post!

Have a good one!

Cheers

Hi again Grant,

Since speaking to you last about my stuttering web video streaming, i've purchased new ram(22gb in total now) My machine is running much better generally and have many apps open without any delays, but, the video issue still remians... Any further advice or ways I can elimenate other things which might be causing the issue?

I have a SSD boot drive so it also makes everything run that little bit quicker so now i'm at a loss to what is causing this, all plugins for FF are up-to-date, system software is up-to-date....

Your advice and help is very much appreciated and i'm looking forward to hearing your thoughts on this..

Cheers

Hi and thanks for the prompt response.

I've had the SSD for a while now, just the RAM upgrade - 2x8gb + 6gb already installed.

I Installed trim enabler when I installed the drive, I went back and checked and it wasn't enabled, now sorted.

Using WiFi, airport extream base station. Using a 3g system to connect to the net with the airpot on bridge mode to extend the distance. 3G WIBE device, cabled(Bridge) to airport base station and connect MP to airport wirlessly. Good DL/UL speeds, video loads fine but still jittery.

The WIBE device also has a wirless signal so 2 networks show up on MP, airport is always used though.

If the internet speed is good and loads the video, would this still cause issues?

Other options other than networking?

RE: SSD and Trim Enabler:

If you have another source of full Mac OS X software, 10.6.8 or later, that you can boot from, Install TRIM Enabler on that also. Then run Disk Utility (Repair Disk) for your SSD with TRIM Enabler fully functioning. The last line will be "TRIM-ing Unused blocks" and it will pause for as long as a minute while all the Deleted Data are removed. Very satisfying and may speed up your SSD.

WiFi:

Whether your WiFi could be a pinch point depends on those readings. Good signal Strength and good Transmit speed (not slowed down from maximum speeds due to interference) indicate a solid connection that will not likely be an issue. Marginal signal strength, slowed down Transmit speed, and using 2.4 GHz band with a dozen Networks around you are Red Flags indicating you could be in trouble from a marginal connection.

Hi Grant,

Well after following you advise above regarding repair disk from a bootable clone or similar, this has solved the issue, I'm sure the additional RAM has helped no end but this has been the thing where i've seen noticable differences, streaming works like a charm, no stutter what-soever. Big thank you Grant, that was really ******* me off 🙂 #legend

Have a great weekend!!

What that procedure does is to free all the deleted data that the SSD drive has been carting along, since without TRIM Enabled, it does not get told when blocks are deleted. Once the SSD knows there are more than a handful of freed blocks available, it can combine them (through its internal garbage collection) into pre-erased SuperBlocks, ready for immediate Writing when needed. That is what provides the speedup.
