High Performance DDR2 Compatibility

[TopChip7]

hey guys.

looking at building a new system but unsure if the memory i've chosen is compatible with the mobo.

Mobo: http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=491417
EVGA 122-CK-NF68 NF680i SLI, S775, PCI-E(x16), DDR2 1200/533/667/800

DDR2: http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=533871
Corsair PC2 10000 (1250mhz @ 5.5.5.18)

Mobo states ok for upto 1200, memory is at 1250mhz.

Can anyone shed light on this please.

Cheers.

The RAM will always be able to clock down, so no worries there. But supporting such a high RAM speed is not easily done. The mobo may have ways of going that high, but of course you're into the realm of OC'ing, where there is no support of any kind. I'm not sure if you could get that mobo up to a PC2 10000 rating. Such things are inconceivable (and unforseeable) for the most part right now, given the stringent "official" RAM support in current chipsets.

The only good answer for a question like this is "go ahead and try it!".

Thanks Saph - You been on holiday?

So is the worst that can really happen if I can't o/c the mobo, is I will have to underclock the ram by 50mhz?
Or better still, are you aware of any quality mobo's about to be released that will support PC 10000 @ 1250mhz?

Can I ask one more please? What size PSU considering 8800GTX, X6800, above ram, X-Fi, and 2 x raptorX hdds - Will 700watt Xclio be enough with a little room for upgrading (not SLI, just xtra hdd, fan controllers etc etc)

Thanks

You been on holiday?Sort of...

I started playing WoW. :D Takes up a lot of time, but at least I can see results in the form of higher numbers (gear, money, levels, etc). This is in stark contrast to work. :p I have many characters on WoW now, but if you ever see a char running around with the name "saphalline"... ;)

Anyways, yes, the RAM will work either way, as long as you give it enough juice. Double-check the reviews and manual of any OC'ing mobo you're looking at to make sure it supports the voltage of your PC2 10000 RAM. If the RAM needs 2.3V and the mobo can only supply 2.0V to the DDR2 RAM slots, then that won't work. Also beware of messing around too much with the timings. Most uber-speed RAM is designed for OC'ing and actually won't work at standard JEDEC specs. So don't count on being able to clock the RAM down to PC2 8000 speeds and lower the timings to 4-4-4-12.

As for the mobo to do it with, the high-end Asus mobo's are your best bet, with other manufacturers like Abit and Gigabyte being secondary. So... what's the most expensive Asus mobo right now? ;)

What are the specs on that PSU? Does it have at least two 6-pin PCIe power connectors? At least four SATA power connectors? A 24-pin main ATX 3.0+ power connector? How about two 4-pin square +12V power connectors, or a single 8-pin? Two or more +12V rails? If it meets the requirements for being an ATX 3.0+ PSU, then 700W should be enough.

lol - could do with a job like yours ;)

Think most expensive Asus at moment is the Striker Extreme with 3 x PCI-e (2@16, 1@8 for SLI Plus a PhysX Card) Unfortunately here in the UK it is still around £250 GBP - Ouch!!!)

As for the PSU it meets all of your stated requirements and at £64 GBP I think it is a bargain (considering the lesser 650W costs £6 more?????)

However - it only has 1 fan (14cm) - wonder if the manufacturers idea of "Ultra Quiet" is actually quiet????

Cheers Saph.


Anyone want to buy my PC????? Make me an offer!!!

Oh, I don't get to play at work. I just meant that it's nice to see progress when you're playing a game. When you work on computers, you don't always see progress! :p

Yeah, that's the one! I told you to look for the most expensive Asus mobo because I knew you'd find that one. ;) It's a beast of a mobo! And from a techie standpoint, it's all pretty and stuff. :p

Even so, it's quite expensive. Check the prices here in the US and you'll see what I mean. I've never seen a consumer-level enthusiast mobo cost so much! Then again, "enthusiast" is constantly being re-defined. Especially in these days of multi-core CPU's and SLI/CrossFire and 8GB of RAM, etc.
