damian Posted July 1, 2008 Posted July 1, 2008 Diamond is prepping its ATI Radeon HD 4870 XOC Black Edition graphics card that will be available exclusively with Smoothcreation's systems. The new card is designed with a custom firmware that enables this card to reach a rather impressive core and memory clocks. The default clocks for the new HD 4870 XOC Black edition card are 800MHz for the GPU and 1,100MHz (4.4GHz effectively) for 512MB of GDDR5 memory. Diamond's custom firmware unlocks the GPU and memory clocks so that they could be raised to 950MHz for the GPU and stunning 1,200MHz (4.8GHz effectively) for the memory. The new card should available tomorrow, exclusively at Smoothcreation's website. It is still not clear if this card is made only for Smoothcreation's systems, but we hope that this card will make it to store shelves as well.

Waco Posted July 1, 2008 Posted July 1, 2008 4.8 GHz effective? DAMN. That's approaching the bandwidth of my 2900XT. Share this post Link to post Share on other sites More sharing options...

Uantyv Posted July 1, 2008 Posted July 1, 2008 They will release unlocked version which can clock to 950mhz it will be factory overclocked by 50mhz only :/ Share this post Link to post Share on other sites More sharing options...
SMeeD Posted July 1, 2008 Posted July 1, 2008 I didnt know the GPU and memory clocks were "locked". I didnt think they locked anything like they do on CPUs. Are they unlocking the voltage? Can someone explain this a little or is it a gimmick? I can believe it if these cards only go into smoothcreation systems, I guess its only a matter of handpicking the high overclockers.

Uantyv Posted July 1, 2008 Posted July 1, 2008 Different oc program so you don't have to go bios to increase core etc... At least thats how i understood. And in other news 4850 is mad thing atm 1.45v 950mhz core Share this post Link to post Share on other sites More sharing options...
firestations Posted July 2, 2008 Posted July 2, 2008 That sounds pretty cool, how much will it be? Share this post Link to post Share on other sites More sharing options...
Comp Dude2 Posted July 2, 2008 Posted July 2, 2008 Different oc program so you don't have to go bios to increase core etc... At least thats how i understood. And in other news 4850 is mad thing atm 1.45v 950mhz core You dont have to go into the BIOS (dont think you even can) to overclock graphics cards anyway so i dont know what difference that is going to make. And is 1.45v high for a GPU core? Share this post Link to post Share on other sites More sharing options...
Uantyv Posted July 2, 2008 Posted July 2, 2008 Check XS forums they BIOS mod radeon clocks and volts. Share this post Link to post Share on other sites More sharing options...
Compxpert Posted July 2, 2008 Posted July 2, 2008 Sad that it is a smoothcreations exclusive. Kinda funny that they offer one but you can't put it in any crossfire setups since the only motherboard they offer is one with an nForce 790i chipset.

IVIYTH0S Posted July 2, 2008 Posted July 2, 2008 if this card was able to sustain the number it's boasting I think we can kiss Nshittia good bye :thumbs-up: Share this post Link to post Share on other sites More sharing options...
Puck Posted July 3, 2008 Posted July 3, 2008 You dont have to go into the BIOS (dont think you even can) to overclock graphics cards anyway so i dont know what difference that is going to make. And is 1.45v high for a GPU core? Indeed you can. Both my x1900xts are bios modded for more voltage, higher clocks, and higher fan speeds. It is especially useful to remove any chance of weird multigpu overclocking quirks due to software or driver issues when trying to tweak more then one card at a time. You can then fine tune through the software and not have to worry about huge changes all at once. For the voltage, just like cpus it depends on the core. 1.45 is quite a bit for wolfdales, but not for a 939 venus for example. Old pentiums used well over 3volts vcore and still barely needed a heatsink-nevermind a fan! The only way to be sure is trial and error over time. As the people who pushed their luck have their cards start dying with severly decreased life, then we all know to scale back a bit from there . Also, the cooling will affect how much voltage is "safe", to a limit. For example 1.6v may fry a "x" gpu in a few hours on air, but be fine 24/7 under phase for years.
