4x2GB on a P5B Deluxe?

[TooNice]

Its not limited by the sata1 interface that afterall would lead to 1.5gb/sec transfer speed which is obviously a stupid amount of speed in theory ssd would be able to reach this speed but it will be good few years before we do...... there is the I-ram on scan which is ddr and I saw on some american forum a similar product by a different company which used ddr2 these adapters are rare though.........

The original SATA interface is 1.5 Gigabit. 1.2 Gigabit without the minus the overhead. Which translate to 150MB/sec as previously mentioned. If you've read the reviews, you'd see that the i-RAM's performance is nowhere as glorious as you'd expect, if you thought that it was going at 1.5GB/sec.

The i-RAM's DDR2 successor (again, unreleased as of yet), was meant to be called 'GC-RAMDISK' when it was first announced. Confusingly enough, that name is used interchangeably with the current i-RAM, which received several revisions (but retain DDR RAM).

Edit: I wonder how the ZeusIOPS perform. The Samsung SSD, as I recall reading about is a start, but not exactly putting even the Raptor to permanent retirement yet. What sort of interface does it run on though? 44x quicker than a hard drive is quite a claim, unless you put a lot of weight in access speed (where SSD would stomp even the fastest SCSI drive).

Yes, I guess so, not read it yet though.

It's a serious amount of money to be spending, so long as it isn't mine.

It uses "SLC NAND flash, which is very high-speed (I should hope so, at that price), upto 44 times quicker than a hard drive"

In the last para of the artical it states, "it may not be suited to every operation, and only really shines when running massive databases".

They also do them in 36GB@£12,050, 73GB@£17,275 and 146GB@£25,265

Good grief, you could by 32x2Gb FB DIMMs for less than the price of the 36GB model. Maybe not perminant storage, but you could always make a copy of it to disk every 5 minutes or so and on power down.

A friend of mine recently did this upgrade himself and had a few issues.

He was using the Corsair DDR2-800 2GB modules and found that he had to reduce his FSB to 266MHz (he was running 333MHz before) before it would work.

Hmmm, now that's not too promising. I won't be running them at 400 anyway, but I need 333 really. Or at least want, in order to get the CPU up to 3GHz. A bit worrisome that....

Guess I'll see what Corsair says about these particular modules. In any case I'll give it a go, the modules can always be returned if they won't work. That'd be real sad though. I guess an i-RAM drive would be an alternative, though a far slower and somewhat less satisfying one.

The P5K might be better able to deal with big RAM modules if you find you're having problems, kinda makes sense using an up to date NB on bleeding edge modules anyway. The P965 is pretty old now.

[Thorburn]

I know of at least one person running 8GB (4 x 2GB) DDR2-800 with an nForce 680i based board and P35, P965's successor, should be launching soon.

When it does I'll dig through the datasheets to find out what it says abouts memory support, as the P965 has some caveats when using 2GB modules.

[Agrippa]

Cheers Thorburn, that'd be awfully nice!

I have considered the P5K Deluxe too, but the fact that an 8800GTX will obstruct at least one of the SATA ports and likely 2, kinda rules it out unfortunately. I could go for one of the Gigabyte offerings though, so I'm certainly not ruling out P35. I know most people would rather have the new and shiny stuff, but personally I prefer the true, tested and mature stuff which won't subject me to unfinished BIOSes and all sorts of niggles. Been there and done that, way too many times. These days I just want things to work exactly as is stated on the tin.

Edit: Ah, hang on. Seems the SATA ports can be used after all then. Goodie goodie, perhaps I'll go for the new and shiny thing after all then.

What sort of interface does it run on though? 44x quicker than a hard drive is quite a claim, unless you put a lot of weight in access speed (where SSD would stomp even the fastest SCSI drive).

The interface is a 2GB dual-port FC-AL (arbitrated loop fibre channel), this fibre optic interface is rarely found in PCs, more commonly to connect storage area networks, and provides up to 4GB/s of bandwidth. The ZeusIOPS has 2 FC-AL ports, so can supply either 200MB/s (single mode) or 400MB/s (dual), using suitable s/ware eg. Veritas Storage.

If you wanted to connect one to your pc you'll need a controller card such as the QLogic QLE2462, which is 4x pci-e (finally a use), this costs £919.78 (but this won't be a concern if you've already handed over £x000's what's another grand?).

It does mention (now I've read some of it, that because of the way most of Windows OS, and common apps arewritten, they are unable to take full advantage of the ZeusIOPS's incredible performance (and there I was with CC in hand, bummer)

About those 8GB again. Having rooted around some more I see Corsair lists the very modules I want as having been tested and verified with the P5B Dlx. Maybe I'll just be real stupid and order those 2 4GB sets right away seeing as they're in short supply and all....

Which modules are you looking at?

As I said a friend has Corsair 4 x 2GB modules and is limited to 1066FSB and DDR2-667.

P965 datasheets explicitly state it does not support the density of memory modules used in 2GB DDR2 at DDR2-800, only DDR2-667.

TWIN2X4096-6400C5DHX

I know theres no official support for them, but having checked at http://www.corsairmemory.com/corsair...or_search.html they come up as tested a found not wanting vs the P5B Dlx.

Well, I just clicked a button and am now poorer. Wish me luck, won't ya?

[aidanjt]

Good luck
