What's your memory assessment speed?

Great score for DDR2 doveman

What is your configuration, 6X2GB or 3X4GB?

What does the CPUZ Memory tab say?

Having 8 out of 12 is not good, have you tried re-seating them?

CPUZ sees 12 gigs. I have swapped ram around. My Intel dealer replace the ram. We have sent the motherboard back to Asus, got the same one back. I have tried 3 different bios. Run the bios at default (Auto) and many many o/c and everything I could find on line. Re-seating cpu cooler many times. I can't get over 1600 with the ram because it won't boot trying all kinds of settings. 6X2, 2 sets of matched ram.

what does the BIOS show?

------------------------------------
In the bios it shows 8184 MB.

How does it score with just 6gb in the correct slots layback Bear? What speed is the ram (sorry if I missed it).

Corsair Dominator DDR2 4GB (running at 1000Mhz, NB 2250Mhz)

Very nice! I really wish the Dominator I got recently worked... You've got the 800MHz version, right?

Thanks. It's 1066 actually, I'm just running it at 1000Mhz as that's where it ends up with a 250FSB.

I don't need to point out you have some serious issues here.

Must be a bad mobo? Did they test the mobo with 12gb in before sending it back?

Sounds like you have exhausted all other avenues.

Thanks, I knew all that tweaking would be worth it eventually

I tested with MaxxMemm when I was tweaking and was surprised at how much difference some settings made (and how little others made). I'll try and find my notes!

I found this, not sure if it works -

i7 930, ASUS P6X58D, 12GB OCZ DDR3 Showing up as 8GB - My fix - Overclock.net - Overclocking.net


Edit, sorry I know its not your memory but the mobo is the same and he had the same issue

As mentioned below in Paul's link, with more than two RAM cards and 4GB RAM or more you might need to bump the integrated memory controller voltage, QPI/DRAM, sometimes the DRAM voltage may need a little bump also.

You can run memtest86+ to test the RAM and motherboard slots.
Have a look at this tutorial.
RAM - Test with Memtest86+
Run it for 8 full passes, with 12GB RAM this may take more than several hours, best to run overnight.
If you get any errors you can stop the test.
Check your DRAM and QPI/DRAM voltages in your BIOS, let us know what they are and we can suggest a bump.

Post a CPUZ tab snip of the CPU, Mainboard, Memory, and SPD tabs.

Let us know if you have any questions.

Nice speeds! That's a Vengeance kit, right? I'll be getting the CMZ4GX3M2A1600C9 (2x2GB) kit with my next upgrade... In theory it should be pretty close to yours.

I have upgraded to 16gig of corsair vengeance LP now. On stock speeds which is 9-9-9-24 CR2 DDR3 1333.

Pity about your CPU only supporting 1066/1333 memory speeds. I bet your RAM will outlast your CPU next time you upgrade...

Depends if I upgrade to a ddr3 cpu or not I guess. Thats one reason I havent sold my ddr 8 gig ram I now got spare now tho, so if I do upgrade and then keep this i5 as a secondary system the old 8 gig is still there to use with it.

Although I want vt-d which this hasnt got (wish I got i7-860 now), I dont see why I should bother with sandy bridge, its only 1 gen up. I could overclock to get the ram running at its max speed but this pc is pretty powerful and is enough for what I need it for.

I must admit, I am slightly confused by that... According to this page, the i5-750 is DDR3 1066/1333..? DDR3 slots aren't backwards compatible with DDR2, so if you're currently running DDR3 then your CPU supports it, just not at their full speeds.

Although I want vt-d which this hasnt got (wish I got i7-860 now), I dont see why I should bother with sandy bridge, its only 1 gen up. I could overclock to get the ram running at its max speed but this pc is pretty powerful and is enough for what I need it for.

That's a valid point... It might change when Ivy Bridge comes out though, according to a note on Wiki, it's expected to have about a 20% increase in CPU power compared to Sandy Bridge... And it's apparently going to be backwards compatible with the Sandy Bridge platform.

I have an i5 750, and am running 1600MHz Ram. I always assumed it was the Motherboard that determined what Ram can be used? A Guy
