I would like to start this thread off by mentioning that this thread
is not intended to be step by step guide.But rather an overview of what other members are doing with getting optimal performance from their rigs.
.Initially excerpts of this preview section were intended to be added
to an OC guide thread that was to be updated occasionally such as
links,drivers,cooling, and software developments.So your comments and feedback will have a vital impact to enhance this thread.
Evaluate what you would like to gain with your overclock the pros and cons and decide.
Evaluate if your current system is in the prime condition that it needs to be to begin..
Some recommended checks would be the overall quality of the case's airflow, proper cable management,psu quality,as well as aftermarket cooling options
Just because you may see a benchmark with hardware that's similar to yours , you may Not be able to achieve similar results ! & hopefully yours may be better
Case and Airflow
A great example of this with some great graphics can viewed in a Tech Talk @ SilverStone's website
***********saw a temp chart elsewhere on this forum with an egg cooking![:)]
Overall PSU Quality and Calculator
********some PSU links and stuff maybe useful here
Monitoring and Benchmark Utilities
***********just a few to get us started
GPU-Z 0.5.1 **GPU-Z Included in Furmark 1.9.0 GPU-Z has been updated to version 0.5.2
Heaven DX11 Benchmark 2.5 :
*****we can easily add some more and keep it current
IMPORTANT! Please remember that there is always
a risk of damage to your hardware when overclocking. That is why it is
very important to monitor your system and its temperatures while overclocking. The
information in this thread is of a voluntary nature supplied by the members of
this forum. The forum members and HOT HARDWARE will not be held
responsible for any damage caused by improper overclocking!
[ thanks 4hams for allowing me to 'borrow' the Disclaimer ]
***********Note to members we can easily update & modify the above sections to suit this community .So your comments and feedback will benefit all of us.
Even though I do not have the best of systems, and need ALL the help I get from you guys,. I thought I would simply kick start a new thread and post with some screen-shots.
Hope that others may join and share their expertise, specs,clocks,temps, benchmarks.,and how they go about it .

FurMark 1.9.0 Download
FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms
to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that's why FurMark is also a
perfect stability and stress test tool (also called GPU burner) for the graphics card.
The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection,
window size, duration.
This benchmark requires an OpenGL 2.0 compliant graphics card: NVIDIA GeForce 5/6/7/8 (and higher),
AMD/ATI Radeon 9600 (and higher) or a S3 Graphics Chrome 400 series with the latest graphics drivers.
The startup interface allows you to tweak the benchmark features such as:
GPU-Z 0.5.1 :
GPU-Z is a lightweight utility designed to give you all information about your video card and GPU.
GTS, 8800 Ultra, 8600 GTS, 8500 GT, 8800 GS, 9600 GSO, 8800 GT, GTS 250,
background and only appear when an update is available (manual update
check is unchanged)
here is a screen of mine at idle with default & modest OC..
MSI Afterburner v2.1.0 (2011-02-15)
**Note one of the first thing you should is In the msi afterburner folder you will find MSIAfterburner.cfg,
open it with Notepad and change the value
EnableUnofficialOverclocking = 0 TO
EnableUnofficialOverclocking = 1Save it over the old file, ** this way should you need to make other changes , other 'tweaking optionsare available
>>>MSI Afterburner Was used to OC the 5770 ..simply by increasing core in increments of 5 and memory in increments of 10 ..monitoring the temps and taking short tests with Furmark while 'tweaking'' the fan profile just a bit....
let's fire up Furmark !
Here's a sceenshot of Furmark in Burn-in mode [Xtreme burn] & setings
Furmark 1.9.0 Bench NO Anit-alias
Furmark 1.9.0 Bench 2X MSAA
>>>Notes: I noticed in the newer version of Furmark my temps initially seemed a bit high so I checked and reapplied TIM with Tuniq TX-2 & did not take pics at the time but noticed and overall lower temps of about 7C on average from factory application.
*** Next Heaven 2.5 Benchmark ...
Current version: 2.5 (2011-03-02)
Heaven Benchmark is a DirectX 11 GPU benchmark based on advanced
Unigine™ engine from Unigine Corp. It reveals the enchanting magic of
floating islands with a tiny village hidden in the cloudy skies.
The distinguishing feature of the benchmark is hardware tessellation,
a scalable technology aimed for automatic subdivision of polygons into
smaller and finer pieces, so that games gain drastically detailed and
more elaborated look almost free of charge in terms of performance.
There are three tessellation modes available in this version of the benchmark:
Moderate ModeThis mode is targeted to provide reasonable performance on a wide range of DX11 hardware.
Normal ModeDefault mode available in the benchmark shows optimal
quality-to-performance ratio. That's the way to achieve prominent visual
difference with hardware tessellation technology.
It is designed to meet the perspectives of the next
series of DX11-capable hardware pushing up the tessellation level to the
extreme in the next 1-2 years
Graphics card: ATI Radeon HD 2xxx and higher or NVIDIA GeForce 7xxx and higher.
Tessellation feature REQUIRES both video card with DirectX 11 support and MS Windows Vista / 7!
Heaven DX11 Benchmark Pro is available for purchase in the official Unigine online store.
Basic edition of this product is distributed completely free of charge, please visit downloads section of the website.
Unigine 'Heaven' DX11 Benchmark 2.5 Download
*** I chose to start with Heaven Benchmark because it easy to use, works great with a variety of GPUS ,and is priced right !
Vsync ON 910/1350 60C / 50% fan average
Vsync OFF 910/1350 60C / 50% fan average
*** So far so good ! always room for improvement and a good start .........
Nvidia - Furmark EVGA Precision & OCCT
Since many have Nvidia Cards and use OCCT
For this section I removed the ATi HD 5770 and and installed a Zotac GTS 250 [DX10 card!}
**Note this is an ECO version of the G92 Nvidia chip ZT-20109-10P Dual 6-pin to 8-pin PCI Express Power Cable 675MHz 2000MHz
With the GTS 250 all previous ATi Catalyst drivers were uninstalled and completely removed using Driver Sweeper.Initially installed Nvidia Driver 266.58... the latest driver for the GTS 250 & did not particularity care for it's performance with this card.Better results with the latest Nvidia Beta Driver 267.24 along with EVGA Precision.2.0.2.
EVGA, once again, sets itself apart from the rest with the EVGA
Exclusive Precision Overclocking Utility. This program allows you to
fine tune your EVGA graphics card for the maximum performance possible,
with Core/Shader/Memory clock tuning, real time monitoring support
including in-game, Logitech Keyboard LCD Display support, and
compatibility with almost all EVGA graphics cards.
Features: * Independent or Synchronous control for fan and clock settings in a multi-GPU system * Allows up to 10 profiles, and ability to assign hotkeys to these profiles to allow in-game * Ability to view temperatures in the system tray * Fan profiling system * Core/Shader Clock Link/Unlink capability * Fan Speed manual or auto adjustment * Real-Time on-screen display support for ingame temp, framerate, and clock monitoring * Logitech Keyboard LCD Display support * In-app temp/clockspeed monitoring of GPU's * Information button shows device, driver, memory size, BIOS Revision and SLI mode * Ability to choose different skins, and make your own! * Now you can save screenshots from your favorite games!
Stock GTS 250
***Noticed that even at idle the temps seemed a bit high and I would have liked a more reasonable GPU fan profile; Furmark is really great for this by simply 'toggling' the Furry Doughnut ! So I checked and replaced TIM.and may post it later in this thread..
****Which is why it always a Very Good Idea to Evaluate & Monitor Temps before launching something like OCCT !
Its features : * 3 different test types o CPU = no RAM tested, alot of heat generated on the CPU, errors are usually CPU-centered o RAM = Maximum error detection, tests the whole chain CPU-Chipset-Memory o Mix = CPU and RAM alternated * 3 tests modes o Auto = 1h long Mix test o Custom (Infinite) = Infinite loop of the test type of your choice o Custom (fixed) = A test of the type of your choice, and of a duration of your choice * Integrated monitoring and System information thanks to CPU-Z and HWmonitor engine * External Monitoring Program support through plugins (Everest, Speedfan, and many more) * Graph output showing temperatures and voltages of your computer

*** Notes :One of the first things to do is to check your settings in the Options for safe CPU Temps and Monitoring !
>>Strongly Recommend that users Evaluate their OC - CPU & GPU running several short 'custom ' stress tests before stressing their systems with OCCT for an hour !!
Looks like there is enough general information here to bring confidence to users optimizing their GPU safely ..
Updated notes and suggestions can easily be added to the above posts.
and encourage others to share with what works for them and how they go about it so that all of us can benefit.[:)]
Nice work rrplay!
nice work guys
Nice work rrplay!
Nice work rrplay!
thanks 4hams !
[quote user="Der Meister"]
Thank you Der Meister !
thanks guys that means a lot and most appreciated
any feed back you can give is certainly going to help with that additional content in the above posts that need additional work
you guys probably have some others to add ..some monitoring apps burn in apps ? screen shots of your own with likely better hardware ?
Even though i posted the OCCT info for CPU in the bios thread for convenience
the full power suppl;y OCCT stress tests should probably be posted here because the full CPU GPU PSU are stressed
*** should getting a new CPU cooler installed 3/16/11 and I 'll be sure to update in this thread and the Bios thread with the new OC ! ashould be interesing to see about getting a comforatable 3.7 ot 3.8 out the i7 870 on air ,a bit more room on the hyper x, cause the Silevratone 600 W 80+ looks like it would have no problem we ill see. heck that's what the graphs in OCCT are for !
Already have a Debain Linux install with Ati drivers and plan on posting some additional info to OC the HD 5770 in Linux
same for swapping the Nvidia vid card
.... dunno probably best to have a separate thread for the ATi / Nvidia / Phoronix Linux stuff
So how do you read this?
hey neil thanks for posting
thats looks great ! and its simple to read
you have the cpu OC to 4.297 ran the furmark burn in a 1680x1050 W with 4X Anti Alias great 60 C temps !! the only things we do not see in your post of the Furmark screeni is the GPU-Z specs and GPU-Z sensors info like the little example screeni in above posts showing those screens
if you play around with Furmarks furry doughnut & toggling' it in and out with the GPU-z sensors screen open you'lll notice the load and fan info change to reflect the loads ...something like that and pretty handy if you want to curve or step a fan profile that ' s may be why i chose to use the EVGA precision with that Zotac GTS 250 card to step a profile with that particular card.
Note that I posted with a lowered 'windowed resolution' to quickly evaluate and lighten the load a bit before a full screen test n bench.
what utility did you use with your 560 Ti ?
Maybe this will give more info,....
Maybe this will give more info,....
hey neil thanks for posting and helping out with Tessmark [:)]
It gives quite a bit more info especially with more current cards such as yours . & I can run it with the Ati HD 5770 not the GTS 250
****Edited the 1st post in this thread to include Tessmark along with your reference to it
and will likely make a similar post as the Furmark above showing the Tessmark GPU tool; when I swap out the cards.[unless you want to post it ? ]
Was also planning before swapping to the Ati HD 5770 to do a another sceenshot post with OCCT / Nvidia GTS 250 and the monitoring apps
> showing the GPU Z sensors tab in real time may be useful & include some shots showing the 'toggling' furry doughnut' graphs with Furmark and GPU-Z sensors tab.
here is a screenshot with Furmark 'Furry doughnut' ftoggled with loads ,temps & fans info
Pretty simple to check out senors tab in GPU Z along the way to monitor averages peaks etc, before full screen runs , some may find this useful
Screen shot of OCCT Power Supply test windowd to show Core Temps etc
From the look oft the graphs that OCCT save after a run loks like I have
quite a bit more headromm on the SilverStone 600W 8+ PSU especially
using the ATi HD 5770 for spu OC and higher OC on GPU
** will have to update new CPU OC in bios thread after 3/15/11 post install of new cpu cooler
