There's a wealth of advice on p67 motherboards and Sandybridge cpu in the relevant hardware sections, but i would rather get a prospective from someone that has/will be using it in the folding/crunching arena and what there particular thoughts are.

Been wanting to upgrade from x58 for a while, as a novice overclocker i found it way to confusing, i have put hours of patience into achieving a good solid overclock not very successfull i have to admit.

So the general consensus the way i see it is an i5 2500k or i7 2600k cpu should be relatively easy to get and maintain a solid 4.5Ghz overclock non?

I read a lot of forum posts and threads eventually decided on a gigabyte ud4-b3. Given that i like my power would i really see an improvement from the 2500k to 2600k i know the latter will give me 4 extra processing threads which would come in handy but an extra £80 hmmmm just not sure.

Now given that your all power mad and believe in wringing the last drop of performance from your hardware :eek:;) what would you do? Am aware of the voltage requirements so its memory shopping today, any thoughts or advice on what might be best please chip in. Would like to get remainder of system ordered over the weekend for a wednesday setup.

Be happy to hear your comments/criticism/input but please keep the "nutter" comments to a minmum :(

Thanks peeps much appreciated in advance :)
 
I've had quite a good experience with the OCZ platinum kits, low voltage so fine for sandy and its been stable as a rock, if anything more stable than the Geil value it replaced, can't comment on how it overclocks though, although thats irrelevent with sandy. If you upgrading then a 2500k is going to be a downgrade if anything so I'd be spending the extra for the 2600k
 
Folding on a 2600K allows the bigadv units and they make one hell of a difference. Pointless to get a 2500K for folding compared to the 2600K.
 
Oh, and I'm on an Asrock Extreme4 because it has holes for 775 coolers allowing me to re-use my existing waterblock, cheap memory because it really isn't that important for Sandybridge and a happy 4.6GHz yielding between 70000ppd and 85000ppd depending on the units.

Yup your right pointless trying to do it on the cheap (wish i hadn't spotted the 580 in mm :)) Will get the i7 2600k, now as far as the memory goes i know you can use triple channel in a dual channel setup, just that i've sold r3 and i7 930 and am left with 12gb corsair xms3 ddr3 pc3-12800c9(1600Mhz)Platinum series.
would you foresee any problems in my using these?
Appreciate the input sah :)

Thanks for that MikeTimbers i will go 2600k but have got a new gpu as well so seeing as seti is my first love...ahem :o then i will split the use between bigadv and gpu crunching on seti. Besides i would get sent to coventry if i were to use 2 580 for folding - be ran out of the country more like :D
Thanks for the input much appreciated :)
 
I cant see any problems with the ram, is it 3x4gb or 6x2gb? If you can get a board with 6 DIMM slots you'll be fine as your running in dual channel, if not could you live with running 8gb in either 2x4gb or 4x2gb configurations.

:) Its 6 x 2gb the ud4 has only 4 memory slots but to heck with it nay more outlay, egg n chips for another month what the heck it's progress :D

Thank you sah and have a good bh weekend :)
 
You can't go triple channel in a P67, it will not do your performance any good. I did the same thing going from i7 920 to 2600K and went from 6GB to 4GB and didn't notice a blind bit of difference. Memory wise I've been ok with OCZ platinum and you'll see it in a lot of my builds. My 2600K however is on Crucial Ballistix, which seems ok so far :)

You will definitely have to go -smp 7 to keep the 580's fed for Seti at the same time as folding on the cpu, see how it goes, you might be able to make up the performance defecit by running bigadv in a vm.

Evening Mr Biffa sah :)

I retract my last statement, looks like egg n chips for another 6 weeks :mad:
Ok so i best be ordering some ocz platinum to get me crackalakking for wednesday build day ...the joy.

Am sure i will find a way of splitting equally between the 2 not ran a vm for years lost my touch on that subject.
Well i can but try, whatever works gets the vote whatever poops gets booted.
Thanks for letting me know Mr B much appreciated :)
 
I was running my 2600K at 4.4GHz on an MSI P67A-GD65 until I took it apart to have the mobo replaced. I was using 4 x 2GB Corsair XMS but have 2 x 4GB RipJawsX (and a Prolimatech Genesis!) for the rebuild. There'll be some Corsair XMS kits in the MM soon.......
 
Hi Snapshot :)

Did you have any problems or are there any dissadvantages to having 4 x 2gb sticks as opposed to 2 x 4gb sticks.
This memory lark has me well flummoxed(don't know if thats a real word) everything else was straight forward.
Some memory at ocuk shows as 1.5-1.65 and given that reccomended volts are 1.5 is that completely safe.
Am not interested in hammering it, having said that a nice stable 4.5 overclock would be nice :)

Thanks for your input much appreciated :)
 
I believe 1.5 is intels recommended for 1155 chips, I'd personally go for some low voltage stuff that runs a 1.35v or there abouts for piece of mind due to Ram voltage being quite unhealthy fro what I recall of chip dying on launch
 
As the memory controller is now part of the CPU, it's believed that two sticks of RAM is less of a load then four so might help the overclock. Intel have admitted that you can take the voltage over 1.5V and the XMS3 ran happily at 1600MHz at just over 1.5V but I thought I'd just give it every chance I could as I was rebuilding anyway. The RipJawsX 2 x 4GB CL8 is on special offer this week and is well worth considering.
 
Thanks guys as allways you've been a hive of information. I realised i could have carried on using the old memory from my i7 ddr3 setup but have settled on the Ripjaws as i was having a lot of trouble finding anything lower than 1.4. But given that Intel have stated the above and OcUk still honour warranty then i will go with the new stuff.

Thanks all i really appreciate it :)
 
The memory controller was part of the CPU in the Westmere i7's as well. But yes 2 is better than 4 in some situations when overclocking although I think thats more to do with suicide runs and extreme overclocking which doesn't really apply when crunching as yes its nice to have fastest, but fast and stable is better :)

My ballistix is 1.65v and hasn't batted an eyelid in my SB setup (version 1)
 
Tbag - Any luck with your new shiney stuff arriving?

I'm still waiting and still no tracking details.

Annoying thing is, I got shipping confirmation at 1.50pm Thursday (last week).

:(
 
Funny you should ask, yup all shiny stuff just arrived even though it said dispatched on the 25th. There was something going on with dxsecure yesterday, i think they had scanned all the items onto the system but then realised they did not have enough room on the trailer so there's a small reason for a delay but not from last thursday.

I had put this off for far too long, on the rampage 3 i had a power and reset button which proved handy as i never got around to wiring these switches up, but until i get the rig up and running i don't have access to the saved files which included a detailed "how to" on wiring.
Am on second machine at the minute and have the 2 switches in the pic, after a bit of uncle google i see that terminals 3 and 4 are to be used if used as a regular power switch - no joy on that theory. Alternatively i have the switch on the right, i would have pulled the last hair on my head out but then i realised i had anumber 2 all over at the weekend :)

Any ideas Mr Loudbob sah? indeed can anyone point me in the right direction :confused:

Much appreciated in advance....shelf full of shiny and hindered by a switch :rolleyes:

 
Have you got a pic of the pins? (reverse side)

Me be thinking there are 6 pins, two will be for led power, two to connect to motherboard and 2 not connected.

Pins 1 & 2 - not connected

Pins 3 & 4 - to motherboard power on switch

last two pins - Power LED from motherboard or from 12v supply (+ & -)

Try google searchon '6 pin vandal switch wiring guide'

Oh ells bells do i need to connect the leds as well? just thought i could use the power switch header on mobo and 3/4 on switch.
Thanks for the help Mr Loudbob sah :)
