Thoughts on OCing for the masses

I thought that I would pose these observances to this August crowd for edification as well as comments:

While I consider myself a rank novice compared to some on this board, I'm far from a nooby. My tech career started in the 70's as a bench tech. I got to handle some of the worlds first CPU's (4004, 8008, etc). Technology has come a long way since then. Several years back I decided to start building my own PC's and have built a few 486's. I played with OCing a little in those days but wasn't very successful as there weren't many that had the knowledge and we didn't have the hardware (water cooling, big heat sinks)to accomplish the task.

Enough of the past and on to meat of my topic. My previous build a single core AMD Athlon 64 for a combination of gaming as well as some other IT/Tech work. I successfully OC'd my processor nearly 500 mHz on a stock air cooled heat sink. Well this got my feet wet and I decided to embark even further on any future builds.

Last year I was able to accumulate what I would call a small fortune, considering I'm a displaced IT person, to build a better more potent rig than my old AMD 64. So I decided, after some considerable gleaning on the internet, to build a new i7 rig. After much consternation and research my meanderings brought me to building an i7 - 860 rig as it gave me the best bang for my buck considering my limited funds. So I purchased some of my components form a local brick and mortar as well as New Egg. I got the CPU at a great price (less than $200 US) and a HAF 932 for a steal. The rest I bought from New Egg. After expending nearly all of my resources, I managed to complete the build (with little difficulty).

Once the machine was up and running, I decided to delve into the dark arts of some serious OCing. With the help of my online resources I was able to OC my new rid to 3600 with no problems. The Corsair H50 seemed to take my little OC well in stride. While I'm sure TT will be aghast that I didn't decide on a Noctua for my cooling chores, I had a stable rig.

I then decided that maybe I could go a step further and see what this new rig would really do. So after some more time on the web, I learned the i7 - 860 could go a little further. So upping the BCLK I did. This brings me to my observations. Keeping temps in mind, I noticed that I could vary my multiplier and base clock and get similar results. To my untrained eye the only differences were the temps. This got me to thinking, what else was I missing. Why would folks only use BCLK to OC as opposed to adjusting the multiplier? Also, I noticed what I considered a strange phenomenon. It seems that while the results of the OCing seem similar they effected the power usage of the rig in different ways. It seems that if I were to utilize a lower multiplier and more BCLK the power usage on the CPU whet down nearly 20 watts. Also, the effect on the CPU temps when utilizing Prime95 were significantly different. The changes lowered my temps several degrees.

So has anyone really checked out the effects of their OCing on system resources? Certain combinations of OCing, utilizing different multipliers and BCLK settings, resulting in significant reductions in power usage. So this is the crux of my questions. Dose anyone ever truly monitor these effects? Or do we just see how much performance we can eek out of our current configuration with out any thoughts on what effects they may have on system resources? Could we get the same performance without upping the strain on the PSU and in turn reducing the stress on other components in the rig (due to heat)? Would we be able to cut power consumption significantly enough to cut wear and tear on other components as well as reduce heating our environs (computer rooms)? As I noticed form many of TT's reviews OCing his systems seems to greatly effect the ambient temps of his computer testing facility.

So I open this topic for comments in hopes it will generate some thoughts concerning my observances. Also, please excuse the length of this topic.

Thanks
 
i, myself using win7ult64, disable all the system services i will never need and set the ones that i use occasionally to manual.

windows is set up, by install default, for utter noobs. it has certain resources that an experienced user knows are eating away at threads and using idiotic chunks of memory.

resources management should be the first thing any serious overclocker does, before attempting to get better clock speeds.

ie: i disable these...

  • Windows Search
  • Windows Media Player Network Sharing Service
  • Media Center Extender Service
  • Microsoft .NET Framework NGEN (after first run)
  • Routing and Remote Access
  • Windows Media Center Receiver Service
  • Windows Media Center Scheduler Service
  • Internet Connection Sharing (ICS)
  • Multimedia Class Scheduler
  • Software Protection
  • Net.Tcp Port Sharing Service
  • WWAN AutoConfig
  • WLAN AutoConfig
  • Windows CardSpace
  • Windows Biometric Service
  • Tablet PC Input Service
  • Superfetch
  • Smart Card Removal Policy
  • Smart Card
  • Secondary Logon
  • Remote Registry
  • Remote Access Auto Connection Manager
  • Remote Desktop Services
  • Remote Desktop Services UserMode Port Redirector
  • Link-Layer Topology Discovery Mapper
  • HomeGroup Listener
  • Fax
  • Bluetooth Support Service
  • Adaptive Brightness

others things like hibernation, screensavers, system restore and virtual memory can also be switched off.

by doing this, system speeds will increase significantly with even doing any OC-ing at all

today congratulations in order are, no more padawan you shall be known as

fun and games aside yes but i do it more for temp/performance reasons than to reduce my power draw as tbh i could care less about that, i wouldnt oc if i did.

to me its a game and intel set the rules for me to bend. intel claim my cpu needs 1.2875v to run @ 2.8ghz i know it needs 1.05v for that speed, i know 1.2875v is enough for a little over 3.8ghz and in normal air temps (under my cooler) it will max out just over 4.4ghz on 1.4v which takes my £140 cpus performance into the same range as people get from the then top of th line qx9750 at a quarter of the price. for what its worth i run it 24/7 @3604mhz on 1.168v with the ram 4:3 @ 565mhz which is plenty fast enough for media center and opera

now with the be and k range of cpu the game has changed, for better or worse its changed but im part of the old school me. its not that hard to knock up the multi until it falls over then increase the juice till its stable again but i enjoy the challenge of balencing the multi/fsb/ram ratio/latencies/straps/volts/temps while tweaking refs and seeking the performance at the ragged edge of stability.

each to their own i guess, i dont like the fancy gui of the uefi yet others think its great :|

dug you want to disable a few more than thos for benching mate
laugh.gif
 
when (and if) i start benching, i won't be using win7... as i know XP is much better for it
smile.gif

Use TinyXP for all 3d benching other than vantage really.

The difference between win 7 and tinyXP was a much as 2000 3dmarks in some benches. Aquamark gives you a shed loads more.
 
Thanks for all the responses.

I find that my new settings use 20 watts less from the system resources and is a bit cooler. That being said, I look for the most bang for my buck when it comes to OCing. I don't want to run the rig into the ground trying to get that last mGhz from the CPU and GPU. There is that pesky law of diminishing returns. Why push the OCing further and cause overdue strain on all the components. I just wondered if anyone else was looking at these things.

this the "overclock3D.net" - lol

a general-use CPU & GPU has a enthuiast's lifetime of 1 or 2 years, being pushed to it's max.

in that time newer CPU/GPUs are released, and we upgrade.

i, for one, do this. i either sell my old rig to reimburse some of the cost of upgrading, or give away the old rig to friends or for prizes in charity raffles.

a new PC is 'old' in 18-24months

The more time I spend on these forums the more nooby I feel.

I know that disabling things that run in the background will free up more resources and make your system run a little faster but I have no idea what half of those are let alone how to disable them.
ohmy.gif


EDIT: How? A guide on the forums might help us noobs eke that extra performance out of our systems.

Wink, wink. Nudge, nudge. Say no more!

agreed still we must learn somewhere right and who could ask for better teachers:)....TO GOOGLE! lol
 
okay guys...

this quickie guide assumes you are running vista or win7, and are an administrator...

  1. right-click on the taskbar and select start task manager
  2. select processes
  3. then click user name to order the running system processes easier
  4. items listed under your username or SYSTEM can be tweaked (LOCAL SYSTEM is a bit harder to do)
  5. leave this window opened
  6. click on the start button and select run
  7. in the box type msconfig.exe
  8. in this system configuration panel select startup
  9. uncheck all the "run on windows start" items that are non-essential
  10. click apply and exit that box
  11. right on my computer and select manage
  12. click services and applications
  13. click services
  14. then click startup type to order the system processes easier
  15. double-clicking on each of these will give you the option to start/stop these, and to choose their startup type

you can use the list that i posted earlier as a guide to what services and apps to disable
biggrin.gif


also...

with the control panel, select programs and features, then select turn windows features on or off

i deselect these:

  • windows DVD maker
  • windows media center
  • all print and document services
  • remote differential compression
  • tablet pc components
  • windows gadget platform
  • and the XPS services and viewer

i hope this helps
 
Some services on this list that I have not stopped so thanks for the heads up
smile.gif
I will try these all tomorrow and see what Super pi says.
