PC 133 mhz SDRAM on intel 810e

[geejo]

When i put 256 MB PC133 SDRAM on intel 810e motherboard it shows only half the size (128MB). But when i put it on my p4 system is shows 256 MB itself

No matter which ever size PC133 SDRAM put on the 810e it only shows the half the size. But if PC100 SDRAM is used it shows the correct size

Why is this so??

Is there any way i could get PC133 SDRAM to work on full capacity on p3 systems with intel 810e boards..

Try a BIOS revision but, and I may be looking at bad info.. but from what I've read the 810e chipset only supports PC-100... It supports PC-133 for the vid card, but not for the DIMMs... probably the problem.

Yeah, I did some more searching around and the 810e chipset only supports SDRAM 100/66 doesn't go for the full 133, that's probably why you're running into issues, you could try a BIOS flash, but I doubt it'll help. Anyone else?

PC133 MHZ works fine on intel 810e but the problem is that it will show only half the orginal capacity

eg -- 256MB will show only 128MB

could any one suggest a work around for this problem

It is the difference between low and high density memory. The board only supports low density ram, that's why your high density PC133 shows up as half. You need to get low density ram for it.

Got to a site like crucial.com or memman.com that has a memory selector.

If you had a stick of high density PC100, it would do the same thing.

Different guy, same problem, I explained it pretty well in my post on that thread.

Short answer: it's a limitation of the chipset. No software revision can overcome it.

Thanks guys for ur help

Yes intel 810e supports only low density ram . The one i was having was high density....it had nothing to do with PC133 FSB

I have just ordered a PC133 FSB 256MB ram from crucial.com its bit costly ($80) but its rare to find so the price fine..

Thanks Ryoga fo making 16 mb thumb rule which u explained in another topics .It cleared all doubts .
