Buffalo 3700 reads as 2700???

got a 512 meg stick of Buffalo technology PC3700 DDR466 ram from newegg yesterday, but sisoft sandra (2003) reports it as pc2700, is the memory mismarked or is sandra screwy?


legacy electronics ddr reads as-
Memory Module 2 : 87L5EDL0-1RDG 256MB 16x(32Mx4) DDR-SDRAM PC3200U (CL0 up to 200MHz) (CL429496729.1 up to 167MHz) (CL429496728.6 up to 34MHz)

buffalo tech reads as-
Memory Module 3 : 512MB 16x(32Mx8) DDR-SDRAM PC2700U-2533-700 (CL2.5 up to 167MHz) (CL2 up to 133MHz)

i was thinking that maybe sandra is messed up since it's saying the first module is capable of cas latency zero upto 200mhz (ya right) but cpu-z reports it as MELCO DDR-SDRAM PC2700 512MB

cas 2.0
ras to cas 3
ras precharge 3
cycle time 6

Having two speeds of memory really ****s things up.

Also most programs would not read PC3500 and up as PC3500 since its hasnt been approved :D I believe the max official speed is PC3200.. So most programs would only read it up to that...

i know having two speeds screws things up, but i'm running it on a 166mhz fsb, well below 200 so they SHOULD be fine... still shouldn't read the 3700 as 2700, unless it is somehow misenterpreting the 3 for a 2, just wondering it anyone else's buffalo 3700 reads as a different speed...

Take all of your RAM out leaving only the Buffalo RAM.
Of course in slot 1. Now see how Sandra reports it.

same thing...i'm starting to think it's been relabeled. not to accuse newegg, since they are a highly reputable company but it's the only conclusion i can think of, anyone got any ideas?

What version of Sandra are you using? Oh wait.. 2003??? Did you download Sandra MAX3?

Here let me see what my PC3500 says...

You do know it is possible your board is reading the SPD incorrectly :)

Other then that I do not know.. Maybe someone sent it back to newegg with the old swap and newegg resold it as new????

But my PC3500 is reported as PC3200...

You can always just have them swap it out for you... If you are not sure.. Can you post a pic of it?

it's max3...i'll mess with the bios and see if it's the SPD thing messing it up, post a pic of the sandra reading or of the ram stick itself?

The ram stick and if you can get the chip numbers readable :)

That can help.. I can compare it to other Buffalo PC3700 and see if the chips match...

I buy my RAM at a local shop, a couple of times they have given me the wrong RAM. I took it back, they replaced it apologizing. Someone had put it in the wrong bin.

read the numbers off the chips

yeah...cpu-z reads mine as melko pc2700...***???

some crazy **** happened. i turned off "detect by spd" and set it manually, rebooted, xp loads then wants to scan C: like i shut the pc off without shutting down or something, i dont think much of it, then it reboots and the desktop wont load, i hit ctrl+alt+del and explorer isnt running, i try to manually run it, it doesnt exist...i go to my backup drive and copy explorer.exe over, reboot and it works, run norton antivirus and 2 files were infected with Trojan.ByteVerify ...interesting. anyways i'm curious to see if speedy's chip #'s are the same as mine, here is what the chips say

Winbond
317WE
W942508BH-5

Those are the right chips :)

cool, but why is it reading as pc2700, happening to speedy too...should we just not worry about it?

i know mine are 314WE BH-5. I don't have the rest of the numbers on me though...the stickers on the ram say pc3700 and that's all cool, but it registers as Melko DDR-SDRAM PC2700. This is really crazy...:confused:

crazy indeed, i think i'll send it back to newegg if it registers the same on my new board when it gets here... something is screwey.

Memory reads as whatever speed the motherboard is running it at. If you clock it as pc2700, Sandra will say its pc2700. If you clock it at pc2100, Sandra will say its pc2100. Just like your processor.

thing is....it reads it as pc2700 no matter what the bus speed is, i had it at 150 before now its at 166, same thing. by the way i notice in your sig your using a Athlon 500 & SD11 as a footstool, i used run a 500@700 with a goldfinger on that board, everyone said it was the junkiest most unstable board out there but i found it to be the most stable...as a rock, weird. still have the board and processor in the closet, cpu has a really long resistor hanging off the back from a botched soldering mod job i did

yeah...I dont even think that 3700 has a JDEC spec out...dont think 3500 had one until recently...so 3700 is going to be an overclocked version of something.

Its highly possible that what you have is a stick of 2700 that OCs really well, so they stamped it as 3700...

I havent heard of a JDEC for PC3500... I still think PC3200 is the max so far :(

hmm...

either way I wouldnt trust Sandra or whatever to properly ID my hardware.

got a reply from buffalo tech...

Hello so and so,

Sandra is reporting it correctly. That part number was released before the final Intel spec for PC3200 in March.

It is programmed to be backwards compatible with the available computers at that time. It is up to the enduser to set it for whatever speeds their computer can overclock to in the BIOS.


so it appears all if ok...

Yeah, I heard that too - either we got lucky or everyone else sucks. I'm betting on the latter :D As of a couple of days ago, that PC got resurrected as a temporary cad workstation at my office.

Makes sense. I'll take a closer look at what Sandra says about mine anyway. I didn't even realize there was any way for the motherboard to detect what kind of memory you have in it. Usually you have to set it. I know for sure that my post screen reads my cpu as the nearest one to the clock speed I'm running at. Right now it says I have a 2800+. I was pretty sure my memory reads the same way.
