OK so Santa came early this year in the form of my friendly neighborhood postie and a package from overclockers uk. For less than £50 I have picked up 4gb (2x2gb)of Crucial Ballistix Tracer (in possibly the most infuriating packet i've ever had to open).

After running round the house looking for scissors I finally got the RAM free of it's plastic prison and took out my old OCZ ram. I popped in the new sticks, booted into the bios and saved before restarting and booting into windows (I got a pleasant suprise when I didnt have to reactive my Vista 64 which I normally have to do if I so much as sneeze near my system). After checking everything booted ok I loaded up CPU-Z to check it was all detected ok.

Now then this is where it starts to get interesting, a picture paints a thousand words so let the pictures commence.

CPU-Z has my Ram at 4-5-5-15-2T Trc19


I have no idea where those timings came from. Following is a picture of the SPD's


After thinking it may have been a bios issue I booted into the bios and tried using both EPP settings and manually setting the RAM as shown below:
Manual:

Auto:


After much tweaking and twiddling with auto options and manual settings I can't get CPU-Z to show the rated 4-4-4-12 2T.

Anyone able to offer advice or point me in the right direction?

1st thing i'd do is check it with another program like everest or memset.

Tried Everest and it's showing the same as CPU-Z. Hmmmm i'm baffled

That's really strange are your BIOS version and chipset drivers up to date?

Even then if you manually change those settings they should be reflected in Everest or CPU-Z

Yup, latest bios and chipset drivers, it's weird.

Am I really losing out that much with the slightly relaxed timings? It's still running Cas4 and 800mhz just a bizarre hybrid mix inbetween.

To be honest I think you are and trying not to go off topic here but showing you an example.

When I first installed this OCZ RAM on my Giga mobo it recognized it as DDR-800 @ SSTL1.8 with a timing of 5-7-7-20. That using Everest Cache and Memory Benchmark got me around 6000 MB/s on read and write .. latency over 90ns.

Adjusting the DDR overvoltage by +0.30V to obtain the rated 2.1V and also forcing the RAM's default timings of 5-5-5-18 improved Everest to over 8500 MB/s on read and write with a latency of 59.6ns.

Anyway as for the timings I am out of ideas here as if you set them manually they should be set. Has the CMOS battery been replaced ?

I've been playing about and it appears it's just a misreading. I set a cpu overclock in the bios which CPU-Z did not correctly report but when I benched the system the increased score was consistent with the overclock.

Thanks for your help Knight_breed and [hobo]eclipse.
