DDR500 Memclock @ 234 in CPUZ?

top · Post by **top** » Mon May 21, 2007 8:08 pm

I got the Mushkin 2x 1GB DDR500 (3-3-2-8/2.6v-2.9v) and put it in my AN832-SLI Deluxe motherboard. I set the DDR Vcore to 2.8V and I manually entered the stated timings from the brand ( 3-3-2-8 ), and I also set the Memclock to limit to 250MHz.

When I boot up, the POST screen states DDR500 instead of DDR400. But when I get into Windows and see what CPU-Z has to say, everything is right except for the memclock frequency. It reads 234.6Mhz and not 250. Is it me or did I forget to configure something else in Bios?

I tried 2.9V and I still get the same thing. Just trying to get the best outta my memory :D

What motherboard and CPU are you using?

Can you post a screenshot of CPUZ? The main tab and the memory tab.....

You should try reset the bios, especially with new ram!

doesn't sound right... make sure you're using CPU-Z 1.40 or later and post up the screenshot!

Here's the screenie of CPU-Z 1.40:

Well the motherboard default is to read memory up to DDR400, so by resetting bios, it would just go back to 400Mhz.

Although if I set each stick to run @ 250, the POST screen does state DDR500

Bump.

Here's some more screenshots of the BIOS settings and the screenshot of POST:

Change "AI Overclocking" to manual and set the FSB to 200.

That didn't work either. I was given an option to overclock the NB to SB to 250 and I still have 234 in CPU-Z, but as far as trying to do that, everything at default is at 200, even the CPU FSB.

I tried to OC the CPU FSB to 250 and it crashed Bios. Luckily this board has a crash free bios system :D

You could try lowering your CPU multi (FID/VID) and then overclocking the FSB to 250 (leaving the mem on the 200 divider)....it's just another way to get the same results!

I see what you mean. I just figured it out how to do, but it increased my processor speed, no big deal. I set the FSB to 215 now I'm at 3.0GHz and 250Mhz for the ram each.

I'll try that other thingy if I ever decide to go back to 2.8Ghz on the processor.

Thanks for your help!

I know this topic is a couple of weeks old now but i did notice you have BIOS version 1205, you should update the BIOS to 1303, or even the new Beta BIOS release 1405.

I am using 1303 and i won't use the Beta release because i don't see any point in doing so. I will wait until the final release. It's till good to know Asus is working on a new BIOS for our motherboard.
