CMX512-3200 wont run at 400


i9

Recommended Posts

Hi. I recently bought a used gig of Corsair cmx. Unfortunatly one stick was 3200 and the other was 3200C2.

 

This wouldnt be a problem, except that the 3200's SPD claims that it is actually pc2700. From reading on these forums, Ive seen that some sticks had the 2700 SPD chip put in them. Again this wouldnt be aproblem, except that my mobo cannot override the SPD. So for me to get to 400fsb I have to overclock my proc 40 fsb. Which I am willing to do, but I want my memory to be running at the proper 3200 speeds.

 

Is this something I can RMA the stick and have changed?

 

So you know, I have tried all of the BIOS settings in trying to get it to run at 400 as the base. For example, I currently have my CPU fsb set at 210. But my memory is running at 348. This is with the memory set to manual and 400 in BIOS.

 

thx in advance for your help.

i9']k. Thank You

 

 

Sorry to bother you guys. The guy I bought the RAM from is trying to troll me on it. Refuses even to RMA it for me. Told me just to lie to you and get it RMA'd. I cant use this RAM since it is, in my mind defective. The wrong SPD chip was put on it.

 

Is there no way that I can at least have the SPD chip replaced so it will work the way it was intended? Im not looking to get new RAM out of the deal, just RAM that works right.

 

thx for your answer.

The SPD chip can't be replaced.

 

How To Read the Memory Label

 

Check your version #. I'm guessing it's a v1.x. If so, that means it's normal for it to have a 2700 SPD chip. Doesn't make it defective either way.

 

Also, your mobo CAN override the SPD.

 

BIOS -> Advanced -> Chipset.

 

I wish it could but it wont. I currently have it set to 'manual' and '400', but it still runs at 333. Which means that to get it to the 400 I paid for, I have to o/c my proc 30 some fsb.

 

If you can tell me how to get around this, Id be very grateful.

 

Oh and ya its version1.1

With JUST that one stick, and setting it manually to 400, it runs @ 333? How are you checking that it's actually running @ 333 Mhz? Also have you tried different slots?

 

 

Ya Ive tried different slots, and I only have this one stick of CMX512-3200. The other is the C2 model.

Are you running BOTH at the same time, or just testing the 3200 stick by itself?

 

Something else is wrong though.

 

Real Clock 210 MHz

Effective Clock 210 MHz

HyperTransport Clock 630 MHz

 

Your HTC should be 4x your effective clock. I checked the manual, couldn't find the setting (should be something like HTT or HT bus or LDT or HT multi). What speed is your CPU running at?

I cuirrently have my HT set to 3. Didnt want it to be a factor in wheteher or not the RAM was booting, when I was testing it out, and never put it back.

 

I currently only have the one stick in, the cmx512-3200. It runs at 333 no matter what I do. Just the way the Asus BIOS works I guess. It doesnt have a RAM:FSB ratio or multiplier, just a mhz setting.

 

I am fairly knowledgable about o/cing and getting ratios correct, and this RAM just wont bump up. I even flashed BIOS just to on the safe side, no change.

yesssss???? :biggrin:

 

They'll probably be authorized for a replacement tomorrow (err... today) by Ram Guy, but keep in mind 3200's aren't recommended to run with 3200C2s.

 

 

Thanks a lot. I appreciate the help. Why arent they recommended to be run together?
