Hi there


Right setup/built the following system with the intention to overclock:-
Intel X6800 ES Processor
Zalman 9500 CPU Cooler
Intel 975X Bad Axe Motherboard
Corsair PC6400-C3/PC8500-C5 2GB Kit
HIS X1900 Crossfire Master ICEQ3 Card
HIS X1900 XTX ICEQ3 Card
WD Raptor 36GB
Antec P180 Case with fans installed
Sparkle 700W PSU
Zalman fan bracket with 120mm attached blowing over memory, northbridge and graphics
Windows XP Pro
Intel Drivers and updated BIOS along with Catalyst 6.7 drivers.


Here are the results:-

Maximum stable CPU overclock with 1.55v with temps around 60-65c underload

This speed was not 100% stable due to not enough voltage for the CPU and things getting a little too toasty as this system would fall over under extreme strain.


Maximum stable FSB with all BIOS options at maximum voltage

This was the boards maximum FSB attainable, it would boot at 475FSB but would soon fall over, at this setting these were 99% stable, dropping FSB to approx 455MHz was rock stable. Again this was the board not the memory as the Corsair memory was just not breaking a sweat.


CPU Benchmark at 3.90GHz

Memory benchmark whilst at 466FSB

Some 3D Mark Results for you to drool over. The Graphics cards were in Crossfire mode set to performance with clock speeds at 730MHz core and 1750MHz memory. These benchmarks were all ran with the CPU at 3.90GHz accept for 3D Mark 2006 which refused to run at anything higher than 3.8GHz:-


3D Mark 2001 SE

3D Mark 2001 is still my favourite as it actually measures system performance too and loves good FSB and memory.


3D Mark 2003

3D Mark 2006

The results are pretty staggering! If I was running the Machine 24/7 for my own personal use I'd accept a nice stable 3.7GHz on approx a 450FSB which was taking approx 1.45v - 1.50v with temperatures remaining around 55c even in the recent hot weather. Conroe/Alendalle is certainly the new performance king when you consider you can buy the lower end E6300, E6400 and E6600 processors which are too great overclockers for so little money.

So there you go! Anybody on the forum able to challenge these results as I know soon many of you will have Core 2 DUO Systems now that OcUK is shipping product.

I would have liked to have tried the much raved about Gigabyte DS3 as I think that may have got my CPU upto 4GHz and along with a 500MHz system BUS which would be even quicker. As the 965P chipset is no slower than the 975X and at the moment the Gigabyte DS3 seems the best overclockers board on the market.
 
I'm suprised that the Extreme Edition couldn't do much more,


But those are some very nice 3dmark scores :cool: :)
 
Pretty impressive I must say!

That 3dMark 01 score is over twice mine!! :eek:

My DS3 doesn't like OC'ing in the bios at all, so I'll swap you my DS3 for your Badaxe if you like?! ;)
 
Well I can beat your memory score m8 with my 6300.

Nice one m8 :)

Try the Scythe Ninja Plus Heatpipe CPU Cooler with a fan on to cool things down a bit as the P180 and that cooler get rid of the heat in the case pronto,my x6800 @3.2ghz 25c idle and just over 30c load :D

<maddness>, that has to be at least a quad Opty or something? I suspect that system has 8 cores.

No AMDs have SSE4 yet. Thus it must be an Intel or a photochop. ;)

Gibbo, can we have a Folding@Home benchmark? Pretty please? Pretty please with a 486 on top? :p

Well spotted! Its integer and floating-point scores make it 54.6% faster than Gibbo's. If it's a standard C2D, multiply by Gibbo's 3.90Ghz and you get 6.03Ghz? :eek:
