i was going to get a e8600 and oc to 4ghz, but now im thinking to get a Q9550 and oc to 4ghz... it seems possible....
is it?

if so what is the best mb for this? DDR2 i assume..

The best mobo for OCing any Intel CPU is a Intel based chipset. The Asus P5Q Pro is a great one as it has the P45 chipset and unless you plan on CF it will run at full PCIe 2.0 as well as 8GB of DDR2.

The Q9550 can hit 4GHz, will be a bit harder than the E8600 though and will need a bit better cooling than most air HSFs provide.

Then go for the P5Q Pro. Best mobo for OCing any Intel chip and is only about $140.

It should OC fine but not near as wlel as thee P5Q Pro.

It may be cheaper but trust me its a great quality mobo. I have the P35 version, the P5K-E, and its great. OCed my Q6600 to 3GHz with ease and its stable and cool as a rock. Asus makes great mobos and the P35/P45 chipsets are some of the best available.

do the q9550 all have the same stepping? or should i be looking for one particular

There are many q9550 steppings.
However, I am not sure if there are any significant differences. (like with some CPUs)
I just hope to get the newest when I order mine.

Is there a way to order a CPU with specific stepping?

Actually yes there is a newer better stepping. The E0 stepping is said to be like the G0 stepping but for the 45nm quads. From most etailers there is no way to. Some do offer it.

What you would want to do is email the retailer and ask if they can gurantee the newer stepping in your shipment. For the Q9550 the newest is the E0 and has a spec number of SLB8V. You will want to ask if they can gurantee that spec number for your order. But as I said most wont be able to gurantee it and chances of getting a ewer stepping when it is just released is hard. The G0 stepping of the Q6600 took a few months before they were almost 100% guranteed by everyone.

there's only two Q9550 steppings. the first one being C1 and the latest being the E0

SLAWQ (C1)
SLB8V (E0)

when you buy a processor, outside of the box, there is a sticker to the side that has those corresponding numbers, which would tell you what stepping the processor inside is. so look around for it. you can't tell what VID the processor is though. i say the easiest way to get a certain stepping that you want is go to a place like frys electronics or microcenter and buy the processor. you can check for yourself on the box which stepping it is, and if it's the wrong one, tell the person to go back and get you another processor. e-tailers would be harder but give customer service a try when you order.

yeah im in the UK and we dont have many places like that. all online retailers... i have emailed Overclockers.co.uk
October 21, 2008 1:59:54 PM

I'm willing to buy the Q9550.
I'll use it with my Asus P5Q-E which I bought on Ebay for $155.
I think that the P5Q-E is much better than the P5Q Pro.

I don't plan to overclock the Q9550 since I'll use it mainly for gaming and also I want to use the EPU-Engine on the mobo.

Will the price of the Q9550 fall with the introduction of the Nehalem CPU?

whats the difference between the two boards? i DO want to oc.

yes, i also would like to know. but until they come out i guess we wont...

Normally not much. Some little things. Like the best one, the P5Q Premium, has a 16 phase power system the P5Q Pro has a 8 phase power system. That means the P5Q Premium will be a bit better for OCing but will also normally cost a bit more.

Also some are mATX mobos so they may have only 1 PCIe slot and 1 PCI slot and are made for smaller cases. I would go with either the P5Q Pro, P5Q-E or the P5Q Premium. Just look at each one and decide which one you want more.

cheers.
any particular fantastic memory for these suckers?
a c 127 à CPUs

My personal preference is Corsairs XMS2 PC2 8500. I have 4GB of it and its very good. Running it at 4-4-4-12 timings in dual channel DDR2 1333 for a nice 1:1 ratio. Thats what I would suggest as it will give you higher OCing potential. Or you could try the DDR2 1333 RAM. It will allow even better OCing room without having to OC the memory.

ok, im stuck between the P5Q Premium and the P5Q Deluxe.

I think the only diff is the premium has 3 lan and 4 pci-e, deluxe has 2 lan and 3 pci-e... which is fine... if thats it then ill get that one?

also put some Corsair 2GB DDR2 XMS2 Dominator PC2-8500C5 TwinX in the basket.

For the mobo just get the Deluxe. Not sure what anyone would need 3 Lan connections for lol.

As for the memory, great choice. I have that same set, well 4GB of it, and it runs stable at 4-4-4-12 which is lower than the stock 5-5-5-18. One tip though. Once you get the system setup go into the BIOS and set the timings and memory voltage manually. For some reason my mobo set it to 1.8v which was way to low from the required 2.1v and was causing BSoD.

IMO wait for Nehalem i7 to arrive and start selling... but the best time is about 1 month after Xmas time, beggining new year, when the consumer market slows down and prices really drop a lot.

So, one more comment....

yeah agreed. its just trying to hold out, plus if my mate is gonna buy my old bits, dont want him deciding not too...

grr:

I also noted the same price change in my local shop... What could be the reason?

The reason outside the US is that US Dollar is getting atronger against foreign currencies. The prices will drop after Nehalem i7 comes out.
