Intel I850EMV2 MoBo + 1066 RDRAM - Will it work correctly?

[RalfHutter]

I know it's not officially supported but will it actually run at 1066 in this board? Does anyone have any experience with this combo, or links to anyhting that talks about it? Apparently Tom's had their 850EMV2 working OK for this review, but I've never seen anything else written about this.

There's a guy posting in the CPU forum who's having trouble with this combo. Is this normal, or an isolated occurance?

Are there any brands of RDRAM that will work better than others in this board?

Just got back from vacation and saw your thread. There shouldn't be a problem running PC1066 on that Intel board or any i850E board with a 533MHz P4 (the only reason that Intel doesn't officially support PC1066, is that they haven't yet completed their validation of those modules). As a matter of fact, when the BIOS (on Intel boards) detects PC1066 RIMMs, it alerts you as follows:
Serial Presence Detect (SPD) is reporting that PC1066 is installed. PC1066 is not a validated memory speed. Do you wish to attempt to boot PC1066? (Y/N) Press [Y] to continue or [N] to shutdown... Well (FWIW), I pressed [Y] to continue on my Intel D850EMD2 as I'm running 4 x 256MB Kingston PC1066 (along with a P4 2.53) and it's not only rock-stable, it's screaming fast!

None of my friends who are running other i850E boards are experiencing any problems with PC1066 either. One of them has the Gigabyte GA-8IHXP and that beauty is loaded with features! Oh BTW, I recommend Samsung PC1066 or the Kingston modules which I have (they use Samsung chips).

Cheers,,,

Thanks for your reply. In the interim I decided to stick with DDR. Seems to have a future where RDRAM doesn't. Plus it's cheaper. $400 for a gig of Corsair PC3200 XMS vs. $600 for a gig of Kingston 1066 RDRAM.

I got an Asus P4B533-E MoBo and am running my 2.26B at 140FSB (out of the box, first stab at OCing this board) and my Corsair XMS at 187Mhz. Getting memory scores in Sandra about 2900 at 2-3-3-6CL.

Will run Prime95/Memtest86 tonight and (hopefully) go up from there.

That's cool -- enjoy your rig!
