Just remember to erase the vmod when you guys want to sell it off 2nd hand. you never know if the person you are selling has any idea how to maintain a modded GPU...

Aiyo...every card different lah. Sometimes you are lucky, sometimes you are not. I can go 900/1333 without vmod on default voltage but I hate the damn noisy fan on my HIS.

hey guys, any of you tried overclocking in crossfire mode using other tools beside catalyst?

Here's the problem im facing, both of my HD3870 has been pencil modded to 1.45v and both has been tested and is confirmed to be stable @ 950/1300. Then theres a problem, on ati CCC overdrive, max clock is only 880. So... i used rivatuner instead, and yes it works... but only on the main card, when overclocking the second card, it always reverts back to its stock speed.

Is there any ways to run both of the card at the same speed? does anyone knows any link to mod the bios? im thinking to set 950/1300 as bios stock speed so that both card will run and stay that speed without having to install too many apps.

Since you are brave enough to vmod, I don't see why you are still thinking (read=hesitating) of moding your BIOS tongue.gif

Push your OC-ability to the max but don't ever use it. Let's prolong the life of that GPU...

Hey man...you can increase your CPU's speed up to 3.5GHz. Try OC it a lil more. Mine's 3.5GHz at 1.38750v.

come on guys, 3870 is highly ocable.
it just needs more voltage tongue.gif

Not everyone is as daring as you lah...Most people wants to have a peace of mind, knowing that the card will not die prematurely before the release of the next generation of graphics card so that he/she can sell his current one 2nd hand...And I'm one of them. Although I know how to vmod and maintain it, I'm not too sure the next person in line to own my card would like to own a *scarred* card. It can be reverted easily, yes, but my conscience is not clear...

Thermalright don't use copper, so it's relatively light. It won't break the card lah...

Your GPU core is not properlly OCed. Look at the Rivatuner chart. It goes up and down. Try turning off all those power saving features for your card and use the Rivatuner to OC.
