Hi there

Well done it today:-

Tri-Fire
8 Core Xeon at 3.40GHz
1140MHz Core (Stock voltage)
7160MHz RAM (Stock voltage)
MSI Afterburner 1.6.0 BETA 5 to get higher clocks


Here it is:-

Even more is possible as with the Asus BIOS the cards can hit 1200MHz+ core and 7800MHz+ memory stable.

However for today this shall do, 5000 barrier is smashed. :D


P.S. This is also proof you can Crossfire different models as well, as the master card is running an Asus BIOS, wheras the other two are stock ATI BIOS and Crossfire still performed perfectly. :)

On air (stock cooler) I've managed a stable 1225MHz Core and 7800MHz memory. :)

That is with a modded BIOS though.

This benchmark was run at 1140/7160MHz as did not modify the BIOS on cards.

As such there is a lot more to come, possibly as high as 5500 on this result. :eek:
 
Wow this is getting to be rather impressive. What temps are you reaching at these clocks Gibbo?

Also as this is on stock voltage, have you any idea what maximum unlocked voltage is possible with a custom BIOS? How good is the scaling when overclocking the core?

You guys really have some dream jobs! My PC and I are green with envy (the PC quite literally). :p

1225MHz Core and 7800MHz on a single card is with extra voltage, but within the safe limits of the software, think it was 1.24v for core and 1.7v for memory if I remember correctly. Temperature on a single overclocked card 72c I think, which is up from a previous none voltage increase of 58-62c, so hotter but well within tolerance. :)

Three cards in Tri-Fire with all fans at 100% reached mid 70's temperature wise, so ideally this needs to stay below 95c which will mean fans at least 50% which is quite audible. But just two cards maintain better lower temperatures whilst being more or less silent.
 
When you are running just two cards are you leaving the middle slot free?

When blocks are available, do you think you will build a test rig to see how far they can be pushed under water?
 
well you would not be comfortable to use such high fan speed while gaming , still great result, custom coolers from manufacturers bringing stock 1300mhz+ core should be tasty.
