Yes, in
theory it's extra power for graphics, but I've had just about every combination of graphics cards in those slots and I've never needed to use it.
think am gonna take it back to OCUK n see what they say about it allas i aint got the kit to test it
n aint got the cash
If it's broken, then I'm certain they'll just swap it out.
Under DRAM Configuration, it's about the second last option on the menu, next to where you set the 667/800MHz bootstrap.
On 1:1
266MHz CPU = 533MHz RAM (PC4200!)
333MHz CPU = 667MHz RAM (PC5300)
400MHz CPU = 800MHz RAM (PC6400)
Every extra 1MHz on FSB = 2MHz on the RAM
On 1:2
266MHz CPU = 1066MHz RAM (PC8500)
333MHz CPU = 1333MHz RAM (PC10600)
400MHz CPU = 1600MHz RAM (DDR3 anybody?)
Every extra 1MHz on FSB = 4MHz on the RAM
On 1:1.2
266MHz CPU = 667MHz RAM (PC5300)
333MHz CPU = 800MHz RAM (PC6400)
400MHz CPU = 1000MHz RAM (PC8000)
Every extra 1MHz on FSB = 2.4MHz on the RAM
On 1:1.5
266MHz CPU = 800MHz RAM (PC6400)
333MHz CPU = 1000MHz RAM (PC8000)
400MHz CPU = 1200MHz RAM (PC9600)
Every extra 1MHz on FSB = 3MHz on the RAM
Not sure if I need to give my ram some more juice or what. Problem is once it fails I just can't be bothered sitting testing and finding out whats causing the problem
Effort = Results unfortunately.
It's the bootstrap setting. For CPU FSB upto 400MHz, use the 667MHz bootstrap. For CPU FSB's over 400MHz, use the 800MHz bootstrap.
I think this is common to most Intel chipset boards these days. Certainly ASUS and Gigabyte P35 and X38 boards are like that.
Old age? You said it was rock solid for many years before you noticed the click of death. Is it under warranty?
You do indeed need 2 Cossfire cables connected, and they have to be oriented the correct way. They usually say H1 and H2 on them. H1 is the card nearest the CPU, H2 is the card furthest from the CPU. This is not pointed out in the manual, but if you hook them up the wrong way you do sometimes get a warning message about missing or misadjusted cables.
The Command Rate adjustment did indeed disappear between 1.2 and 1.3, so you'll just have to live with 2T I'm afraid. The RAM options haven't changed, so I'm not sure what's up with yours.
It was an off-topic, private, conversation that we've mutually removed.
It's actually pretty straightforward.
What it says is that if you are using a slow CPU (200-266MHz FSB) then you should use the 667MHz bootstrap option on the DRAM Timings page, and for faster CPUs 266-400MHZ FSB use the 800MHz bootstrap option. The rest of it just tries to explain why - the range of multipliers only goes from 1:1 (actually 1:2) to 1:2 (actually 1:4) and that isn't a broad enough range to cover all CPUs with all RAM, so they have provided two bootstrap settings.
I would go back to the V1.3b BIOS if V1.4 is giving you odd results.

If you are running Vista then turn on the AHCI option in the HDD options. It makes most modern drives a fraction faster.
Not clocking an Intel CPU is almost a sin. Even just turn it up to 333FSB with no other options adjusted. It should be pretty much 100% stable, and quite a bit quicker.
I would say it's most likely the RAM, but you talk about having the CPU voltage set to 'stock'. If that's AUTO then it's anything but stock as the AUTO will increase the voltage by quite a lot to keep an overclock going.
And if you haven't dropped the multiplier then you're running 4.2GHz - yes? If so, I'd be quite pleased with that, really.
Yep - you're right - I forgot that the E6750's are 333MHz FSB at stock. You definitely need the 800MHz bootstap when you're running over 400MHz, and, if your RAM is manually set to it's 'correct' settings (4-4-4-12) you might want to put your RAM on AUTO so it will loosen the timings for you. I've had some of that GeIL RAM and I would expect it to run harder than 840MHz - I've seen 1000MHz out of at least one pair at about 5-6-6-15 so you may want to check that out.
I think you may also be needing to turn up the Northbridge voltage a touch too as 420FSB is quite a lot more than 333FSB which is where it probably thinks it's it's running.
On the CPU voltage you're probably looking at about 1.45V to make an impact - seriously! - 1.35V is quite conservative on that CPU.

I'd go back to 1.3b to be honest. It's not broken really, so why not? And one thing's for sure - all the options definitely work in 1.3b.
