ATi Radeon HD 6950 to HD 6970 Mod
AMD Radeon HD 6950 to HD 6970 Mod
Introduction
A few weeks ago AMD released the Radeon HD 6970 and Radeon HD 6950. Both cards are based on AMD's new Cayman core which is their first graphics processor to use a VLIW4 shader configuration.
Just like on all other similar products, AMD's two Cayman variants, called Cayman Pro and Cayman XT, are based on the exact same GPU silicon. The model variant a GPU chip becomes is decided after the die is produced, at some point before it is put on the card. Creating new SKUs from the same silicon by locking features has been common practice in the industry since at least the Radeon 9500 in 2002. This article is to unlock the Radeon HD 6950. The HD 6970 has nothing that can be unlocked.The picture above shows the disabled HD 6950 shaders in red. When unlocked, these deactivated units become active, resulting in a substantial performance increase. AMD has two methods of locking the shader count on all of their recent GPUs. The first one relies on fuses inside the GPU, or on the substrate - a mechanism similar to Intel's multiplier locking. It is not reversible as far as we know. The second mechanism is the one we are interested in, AMD can configure the VGA BIOS in a way that it disables extra shaders, in addition to the ones disabled via the on-die fuses. This method is mostly used to create engineering samples or reviewer cards that match the target specifications. Usually production cards come with the shader count configured in the fuses, so that it can not be changed. Apparently currently shipping Radeon HD 6950 cards from all manufacturers - which actually are all the same card with different sticker - have their shaders locked via the BIOS method, so we can exploit it easily.
Unlocking the shaders
Unlocking the additional shaders is done by flashing the card with a HD 6970 BIOS. You can find a few in our VGA BIOS collection. Any of these BIOSes will work on any reference design HD 6950 card. You could use the ASUS BIOS which comes with higher clocks & Overdrive limits and enables voltage changes via SmartDoctor, or stick with one of the reference BIOSes in case you are afraid the clocks might be too high. I will describe the method for flashing from within Windows, which is safe enough on these cards because of the dual BIOS feature that enables easy recovery. - Grab ATI Winflash from here (32 & 64-bit).
- Download HD 6970 BIOS. The Sapphire one I linked to will work on all reference design cards from any vendor.
- Make sure the BIOS switch on the card is set to the 1 position (pictured further down if you don't know where it is).
- Run ATI Winflash, click Save to save your BIOS, so you have a backup in case something goes wrong.
- Load the HD 6970 BIOS into Winflash by clicking Load Image, followed by Program.
- Let the flashing process complete and reboot your system.
- Check the shader count using GPU-Z, it should show 1536. Make sure you use version 0.5.0 or newer, the official 0.4.9 version does not support HD 6900 Series properly. If you see a shader count of 1600, your GPU-Z version is outdated.
- To ensure maximized performance open Catalyst Control Center, go to the Overdrive tab and set the PowerTune slider to the +20% setting. The "Testing" section of this article has more data on that.
- Check stability in Windows desktop applications and games.
Testing
We can see that enabling the shaders without any clock increases improves performance. Once the clock speeds are adjusted to match the HD 6970, the card effectively performs just as well as a full blown Radeon HD 6970. 
I did some additional power consumption tests and it seems that AMD's PowerTune power limiting system does not get "upgraded" by the BIOS flash. We see that even when modded, the HD 6950 (at HD 6970 shaders and clocks) runs into the PowerTune limit earlier than the regular HD 6970 which results in reduced power draw but also reduced performance in Furmark. With a power consumption of 202 W, the modded HD 6950 is well below the 225 W specification limit of the HD 6950 power configuration. Once we up the power limit in Catalyst Control Center by +20%, we see that the modded HD 6950 draws 252 W, which exceeds its specification (225 W) by 27 W. This move also improves rendering performance by a good deal, so I would recommend it to all users who perform this mod and have a half-decent power supply. Going 12% beyond the specified power limit will not have any ill effects on your hardware and is well covered by manufacturing tolerances and overspeccing, but it reduces the possibility of stuttering or other performance slowdowns caused by AMD PowerTune. What if something goes wrong?
So you flashed the BIOS and your card doesn't work for one reason or the other? If your card boots fine but does not work reliably in 3D, you can just boot the card and flash back the original BIOS of your card (that's why you should always save your BIOS before doing any flashing experiments.
In case your card does not boot at all you can use AMD's new backup BIOS feature: - Set the BIOS switch (pictured above) in the 2 position to enable the recovery BIOS and restart the computer. This will let you boot the card without problems.
- Boot into Windows/DOS prompt and get ready to flash the card - do not start the flashing process just yet.
- Set the BIOS switch in the 1 position with the system running and ready to flash.
- Flash your saved BIOS to the card.
- Reboot, done.

The latest in hardware and gaming
Looks like Santa brought an extra present for us hardware enthusiasts this year. Thanks to a less secure locking method AMD's new Radeon HD 6950 can be unlocked to a full blown HD 6970 with a few mouse clicks. As detailed in our article, you can safely perform the flashing process from within Windows. In case something goes wrong it is easier than ever to recover the card thanks to AMD's new Dual-BIOS feature. We tested the unlock on three HD 6950 cards: one AMD engineering sample, one HIS media sample and one ASUS retail card. All of them unlocked perfectly and run at HD 6970 speeds now. More success reports are compiled into a table at the end of the modding article.

Upgrade ESX 4 Update 2 to ESX 4.1
Problems with VUM (VMware Update Manager) lead me to upgrade our ESX 4 U2 hosts to ESX 4.1 using the command line. During the upgrade, I was getting an error about a certain rpm package that would not uninstall properly (esxupdate error 15), so I've included that as part of my instructions.
To prepare for the upgrade, you need to download the ESX pre-upgrade zip file as well as the 4.1 upgrade zip file. I used WinSCP to copy them to the /tmp directory on each ESX host, then put the hosts in maintenance mode using vCenter before doing the upgrade. The whole process is pretty quick once you've downloaded and staged the zip files.
Note these instructions assume you use sudo for admin tasks, if not, leave it out.
1. install pre-relase patch: sudo esxupdate update --bundle=/tmp/pre-upgrade-from-ESX4.0-to-4.1.0-0.0.260247-release.zip
2. install upgrade: sudo esxupdate update --bundle=/tmp/upgrade-from-ESX4.0-to-4.1.0-0.0.260247-release.zip
3. remove RPM from update 2 that won't remove autmatically (the first command checks to see if it is still installed, the second removes it if it is still there): sudo rpm -q vmware-esx-apps-4.0.0-2.17.261974 sudo rpm -e vmware-esx-apps-4.0.0-2.17.261974
4. reboot sudo reboot
5. Afterwards, you can log back in and check the host version: sudo vmware -v
Jerry Blogger's Prediction
On , there would be a big accident in around Toronto area which would involve a good amount of people.
I sense it half year ago actually. A very strong feeling that would occur on the Mid-night of 27th or maybe 28th since it would be a the moment of date changing.
So, I suggest people stay home on 26th to 28th
